    Purpose

    Parkinson disease is a prevalent neurodegenerative illness of the central nervous system that causes significant disability. Neurological and memory impairments are hallmarks of dementia, which has significant therapeutic implications for patients with Parkinson disease and is associated with elevated mortality. Non-motor symptoms, in addition to the traditional motor symptoms, were commonly acknowledged components of the clinical picture. Cognitive decline, including problems with memory and attention, was a crucial feature of the disease since it adds a great deal of burden to both the patient and caretakers. So, this study aims to find the effectiveness of cognitive behavioral therapy and aerobic exercise on the attention and memory in Parkinson disease dementia.

    Methods

    A pilot study was conducted with 30 patients diagnosed with Parkinson disease dementia who had mild to moderate impairments in cognitive functions such as attention and memory. The participants were randomly divided into two groups, and the study was conducted in a private setting. Group A (n=15) received cognitive behavioral therapy, and group B (n=15) received aerobic exercise for 6 weeks daily for 30 minutes. Parkinson disease-cognitive rating scale and mini-mental state examination were used as outcome measures. 

    Results

    Cognitive behavioral therapy demonstrated a significantly greater improvement in cognitive functions than aerobic exercise (P<0.001), evidenced by paired and unpaired t-tests.

    Conclusion

    The study concluded that cognitive behavioral therapy significantly outperforms aerobic exercise in enhancing attention and memory in dementia associated with Parkinson disease. These findings highlight the effectiveness of cognitive behavioral techniques as a key therapeutic intervention for improving cognitive function in this population.

    Purpose

    The scientific methods for evaluating muscle activity involve the use of various techniques. Biofeedback, which consists of equipment providing individuals with real-time feedback regarding their physiological responses, is crucial in enhancing neuromuscular function. Despite its potential, the effectiveness of biofeedback interventions on motor performance remains a topic of debate. This study aimed to investigate the effectiveness of different biofeedback interventions on motor performance improvement in hand. This study contributes to a more comprehensive understanding of the role of biofeedback in motor function improvement in hand.

    Methods

    A total of 60 individuals were randomly assigned to one of four groups: Aircraft, visual gauge, pattern-tracking, and a control group. Preintervention and postintervention assessments were performed to evaluate motor performance in hand. Statistical analysis was conducted using the paired t-test to compare the root mean square error between groups.

    Results

    The pattern-tracking group demonstrated significant motor performance improvement, with a statistically significant difference in root mean square error (P<0.001). This finding suggests that this specific biofeedback approach may effectively enhance motor performance in hand.

    Conclusion

    The study’s findings support the task-oriented approach, which emphasizes the importance of adaptability to environmental changes, and the part versus whole training theory, which argues that breaking down a motor task into smaller components improves performance. The results highlight the importance of similar practices to the final objective for motor function improvement in the hand area. The study’s findings have implications for developing effective biofeedback interventions for motor performance improvement in individuals with hand-related motor impairments. Furthermore, the conclusions can be applied to various populations, including athletes and individuals in different lines of work, who can benefit from improved motor performance in their hands.

    Purpose

    Karate is one of the most popular martial arts in the world, but its practice carries the risk of injury. This study examines the mechanisms and prevalence of injuries in female elite kumite karate players.

    Methods

    This retrospective study investigated the prevalence of acute and chronic injuries during the last 6 months in black-belt female Karate players. The Oslo standard questionnaire was used in this study. This questionnaire covers musculoskeletal system care, comprising the severity of the injury, the location of the injury, the type of injury, the mechanism of injury, and the time of injury.

    Results

    Results indicated that the knee was the most common location of acute injuries (χ2=248.052, P=0.001), and the lower back was the most common location of chronic injuries (χ2=129.342, P=0.001). Also, the findings showed that acute contact injuries are more prevalent than non-contact injuries (χ2=7.936, P=0.05), and these injuries have occurred more during training (χ2=7.263, P=0.064). In addition, the results demonstrated that sprain and fracture have the highest percentage in acute injuries (χ2=154.356, P=0.001) and other injuries and tendonitis have the highest rate in chronic injuries (χ2=7.263, P=0.064).

    Conclusion

    The knees and lower back are more prone to injury than other body areas. Coaches and athletes should consider preventive programs to help decrease the risk of injury in these areas.

    Purpose

    Plantar fasciitis (PF) is a leading cause of foot discomfort and significantly impacts the overall quality of life. Trigger points dry needling is an alternative treatment for heel pain. 

    Methods

    This study aimed to evaluate the effect of the quadratus plantae muscle dry needling on pain and variations in the thickness of the plantar fascia among individuals with plantar fasciitis using ultrasound imaging. Forty patients in the intervention and control group were taught to massage and stretch the plantar fascia for 2 weeks. The patients in the intervention group underwent quadratus plantae muscle dry-needling twice a week for 2 weeks. Plantar fascia thickness and pain were measured with ultrasound and visual analog scale, respectively. Study variables were measured before the first and last sessions in both groups. To analyze the data, paired t-test, and independent t-test were used with a significance level of 0.05. 

    Results

    No significant difference in pain reduction was shown in between-group comparison (P=0.077). Between-group comparison after 2 weeks of treatment indicated a significant decrease in plantar fascia thickness following dry needling (P<0.001 with a moderate effect of 0.33). 

    Conclusion

    The results of the present study showed that quadratus plantae muscle dry needling is significantly effective in improving pain and reducing plantar fascia thickness in patients with plantar fasciitis.

    Purpose

    Many available questionnaires fail to distinguish between the severity of symptoms and functional limitations caused by neck pain in different areas. Therefore, determining symptoms and functional limitations that are associated with existing neck pain is difficult. The lack of a specific questionnaire for functional symptoms and constraints related to neck pain in Persian has made it necessary to develop new and reliable tools in this field. Therefore, this research aims to localize and validate the Persian version of this questionnaire. 

    Methods

    The questionnaire was finalized after necessary corrections were made using the translation back-translation method. The content validity index (CVI) and content validity ratio (CVR) were used to ensure content validity. The internal consistency test (Cronbach α) reliability and test re-test reliability were assessed. 

    Results

    The CVI results indicated that all questions scored above 0.79 in communication, clarity, simplicity, and ambiguity. The questionnaire demonstrated a high level of content validity with an S-CUI/Ave (scale-level. CVI. based on the average. method) of 0.94. Statistical analysis revealed high internal consistency for the symptoms (27 questions, Cronbach α=0.91) and functional limitations (20 questions, Cronbach α=0.93) sections of the questionnaire.

    Conclusion

    After conducting the questionnaire, it is possible to identify people with varying levels of pain and functional limitations associated with neck pain. It can help determine the progression of symptoms and limitations.

    Purpose

    Low back pain (LBP) is a health problem. Rehabilitation could be a suitable therapy for LBP patients. Nonetheless, the effectiveness of movement pattern training on LBP patients has not been assessed scientifically. So, this research examined the effects of movement pattern exercise on general lower limb muscular co-contraction in patients with non-specific chronic LBP during walking.

    Methods

    The current research was quasi-experimental. Forty male adults who experienced non-specific chronic LBP voluntarily enrolled in this study. Twenty samples were assigned in the intervention group and 20 in the control group. The exercise protocol used in this study was based on the Harris-Hayes et al. protocol, which takes 18 supervised training sessions (during 6 weeks). The assessments were conducted before the intervention and again after 6 weeks. General co-contraction of the lower limb muscles was recorded using electromyography while walking, and the total activation of the muscles that abounded the joint was calculated. 

    Results

    The findings indicate a significant decrease in general co-contraction of the ankle in the intervention group at propulsion (P=0.011, ƞ2=0.160). Also, the results show that at the loading phase, general knee co-contraction is greater in the experimental group compared with the control group (P=0.037, ƞ2=0.110).

    Conclusion

    Our research reveals that the training program improves the general co-contraction of the lower limb muscles in individuals with LBP.

    Purpose

    Opioid use disorder has increased worldwide in recent years, and Iran ranks first in terms of opium smoking in the world. Opium smoking by traditional methods, in addition to dependence on morphine, is a behavioral addiction in Iran. The body position during opium smoking is usually non-ergonomic. This study aims to compare sway-back posture and musculoskeletal problems between opium smokers and non-drug users. 

    Methods

    This cross-sectional research is a comparative study. We selected 80 people with opium use disorder (whose main method of their consumption was smoking) and 74 non-drug users. We compared them regarding sway angle (sway back posture) and musculoskeletal complaints (NORDIC questionnaire), and the association of possible risk factors was investigated. We analyzed data using the Kolmogorov-Smirnov test, correlation coefficient, and paired t-test using SPSS software, version 23. 

    Results

    Two study groups were significantly different in terms of sway back posture (P=0.007), neck (P<0.001), upper back (P<0.001), and lower back (P=0.006) musculoskeletal complaints. Homelessness had a significant correlation with sway back posture and musculoskeletal complaints. Also, the daily duration of opium smoking (in minutes) and opium smoking duration in lifetime (in months) were significantly correlated. Homelessness was the strongest predictor and had the strongest correlation. 

    Conclusion

    In general, increasing the duration of sitting in non-ergonomic positions can increase sway angle and sway back posture and increase musculoskeletal complaints of the neck, upper back, and lower back due to the non-neutral posture of opium smoking. It seems that plasticity and structural and functional adaptations of the posture occur due to opium smoking. So, further studies are recommended.

    بیماری های قلبی عروقی عامل اصلی مرگ و میر در جهان محسوب می شوند. بر اساس آمار سازمان بهداشت جهانی، در سال 2022 این بیماری ها موجب مرگ نزدیک به 8/19 میلیون نفر در سراسر جهان شده است. یکی از اصلی ترین چالش های پیش رو در مدیریت این بیماری ها تشخیص زود هنگام و درمان به موقع این بیماری ها است. به طور کلی برخی از نشانگرهای مورد استفاده در حال حاضر اختصاصیت چندانی ندارند، لذا نیاز به نشانگرهای اختصاصی تری در این بیماری ها به شدت احساس می گردد. اگزوزوم ها، به عنوان یکی از ویزیکول های خارج سلولی تقریبا در تمامی سلول های یوکاریوتی تولید می شوند. این میکرووزیکول ها با یک غشای دولایه فسفولیپیدی پوشیده شده اند و پروتئین ها، اسیدهای نوکلئیک، لیپیدها و... را حمل می کنند.

    مواد و روش ها

    مطالعات انجام شده در این زمینه از طریق یک مقاله مرور روایی مورد بررسی قرار گرفتند و مقالات موجود در پایگاه های بین المللی PubMed، Scopus و Web of Science را در بر می گیرد.

    یافته ها

    عوامل متعددی از جمله استرس، آسیب سلولی، داروها و سموم بر تولید و ترشح اگزوزوم ها تاثیر می گذارند. اگزوزوم ها نقش مهمی در ارتباطات بین سلولی ایفا می کنند و می توانند به عنوان نشانگرهای زیستی برای استراتژی های تشخیصی و پیش آگهی عمل کنند. همچنین اگزوزوم ها دارای پتانسیل درمانی هستند و به عنوان ناقل های زیستی برای ارائه داروها به شیوه هدفمند به قلب عمل می کنند.

    بحث و نتیجه گیری

    استفاده از اگزوزوم ها در تشخیص و درمان بیماری های قلبی عروقی می تواند به مدیریت بهتر این بیماری ها کمک کند، اما این کاربرد با چالش هایی در زمینه بالینی مواجه است. این مقاله به بررسی پتانسیل اگزوزوم ها به عنوان ابزاری نوین در این زمینه می پردازد.

    Background

    Cardiovascular diseases (CVD) are considered the leading cause of mortality worldwide. According to World Health Organization statistics in 2022, these diseases resulted in the deaths of nearly 19.8 million people globally. The early diagnosis and timely treatment are among the main challenges in managing these diseases. Generally, since some of the currently used biomarkers lack specificity; therefore, a stronger need for more specific markers in this area is felt. Exosomes, as one of the extracellular vesicles, are produced in almost all eukaryotic cells. These microvesicles are covered with a bilayer phospholipid membrane and carry proteins, nucleic acids, lipids, etc.

    Materials and Methods

    The current narrative review research included studies available in the international databases of PubMed, Scopus, and Web of Science.

    Results

    Various factors, including stress, cellular damage, medications, and toxins can influence the production and secretion of exosomes. Exosomes play a crucial role in intercellular communications and can serve as biological markers for diagnostic and prognostic strategies. Additionally, exosomes have therapeutic potential and act as biological carriers for targeted drug delivery to the heart.

    Conclusion

    Based on the findings obtained, the use of the exosomes in the diagnosis and treatment of cardiovascular diseases could aid in the better management of these conditions; however, its application may be clinically challenging. Moreover, the present study explores the potential of using exosomes as a novel tool in the medical field.

    مقدمه

     تغییرات پایدار در روان درمانی بر پایه مکانیسم های زیربنایی آن شکل می گیرند. یکی از این مکانیسم های کلیدی تثبیت مجدد حافظه (Memory Reconsolidation) می باشد. این فرآیند زیستی شامل به روز رسانی و اصلاح اطلاعات حافظه بوده و به عنوان مکانیسم بنیادی تغییر در روان درمانی که منجر به تغییرات تحول آفرین می شود، معرفی می گردد. بنابراین هدف این پژوهش، بررسی تثبیت مجدد حافظه به عنوان مکانیسم بنیادین تغییر درمانی که پلی میان علوم اعصاب و روان درمانی است، می باشد.

    مواد و روش ها

    این مطالعه یک مرور روایتی بر گرفته از رساله دکتری روانشناسی است که مقالات مرتبط با کلید واژه های (Memory Reconsolidation، psychotherapy و therapeutic change) از طریق جست وجو در پایگاه های علمی معتبر PubMed،ScienceDirect ،  PsycINFO، Scopus و موتور جستجوی Google Scholar در بازه زمانی 2024-1985 جمع آوری شده اند. در مجموع از بین مقالات انگلیسی زبان دارای متن کامل، 48 مقاله مرتبط با موضوع و اهداف پژوهش استخراج شدند.

    یافته ها

    مطالعات نشان می دهند که تثبیت مجدد حافظه مکانیسم تغییر مشترک در بین رویکردهای روان درمانی بوده و از طریق تغییر در ساختار حافظه، به روزرسانی و اصلاح خاطرات ناسازگار و در نهایت بازسازی شناختی-هیجانی می تواند باعث تغییرات پایدار و عمیقی در بهبود مشکلات و اختلالات روانی شود.

    بحث و نتیجه گیری

    نتایج نشان دادند که همگرایی علوم اعصاب و روان درمانی از طریق مکانیسم تثبیت مجدد حافظه به عنوان گامی نوین در توسعه شیوه های درمانی کارآمدتر در نظر گرفته می شود. بر همین اساس تمرکز بر تثبیت مجدد حافظه در روان درمانی می تواند اثربخشی درمان را به طور معناداری ارتقا داده و موجب تغییرات عمیق و پایدار در مراجعین شود. بنابراین، پیشنهاد می شود پژوهش های آتی بر توسعه مدل های درمانی مبتنی بر مکانیسم تثبیت مجدد حافظه متمرکز شوند.

    Background

    Sustainable changes in psychotherapy are formed based on its underlying mechanisms. One of these key mechanisms is Memory Reconsolidation. This biological process involves updating and modifying memory information and is introduced as a fundamental mechanism of change in psychotherapy that leads to transformational changes. Therefore, the purpose of this research is to investigate memory reconsolidation as a fundamental mechanism of therapeutic change that bridges neuroscience and psychotherapy.

    Materials and Methods

    This study is a narrative review derived from a PhD dissertation in psychology, in which articles related to the keywords (Memory Reconsolidation, psychotherapy, and therapeutic change) were collected through searches in the reputable scientific databases PubMed, ScienceDirect, PsycINFO, Scopus, and the Google Scholar search engine, within the time frame of 1985-2024. In total, 48 articles related to the topic and objectives of the research were extracted from the full-text English language articles.

    Results

    Studies show that memory reconsolidation is a common mechanism of change among psychotherapy approaches, and through changes in memory structure, updating and modification of maladaptive memories, and ultimately cognitive-emotional reconstruction, it can cause lasting and profound changes in psychological problems and disorders.

    Conclusion

    The results showed that the convergence of neuroscience and psychotherapy through this mechanism is considered a new step in the development of more efficient treatment methods. Accordingly, focusing on memory reconsolidation in psychotherapy can significantly enhance the effectiveness of treatment and lead to profound and transformational changes in clients. Therefore, it is suggested that future research should focus on developing therapeutic models based on the mechanism of memory reconsolidation.

     ناهنجاری های الکتروکاردیوگرام و آریتمی های قلبی بعد از سکته مغزی بسیار رایج هستند. این مطالعه به بررسی اثر IC87201، یک مولکول موثر بر مسیر سیگنالینگ درون سلولی گیرنده NMDA، بر کاهش طولانی شدن فاصله QT، به عنوان شایع ترین تغییر الکتروکاردیوگرام پس از ایسکمی مغزی، در موش های صحرایی نر پرداخته است.

    مواد و روش ها

    در این مطالعه، 15 سر موش صحرایی نر بالغ به طور تصادفی به سه گروه MCAO، MCAO+DXM (دکسترومتورفان هیدروبروماید مونوهیدرات، آنتاگونیست گیرنده NMDA)، و MCAO+IC87201 تقسیم شدند (5=n). دو ساعت پس از ایسکمی، در این سه گروه به ترتیب حلال، DXM و IC87201 به صورت داخل صفاقی تزریق شد. امتیاز رفتاری پیش از ایسکمی و چهار و چهل و هشت ساعت پس از آن با استفاده از آزمون نقص عصبی (NDS) سنجیده شد. تفاوت های آماری با استفاده از آنالیز واریانس با مقادیر تکراری (ANOVA repeated measures) بررسی شد (05/0<p).

    یافته ها

    فاصله QT به طور قابل توجهی پس از ایسکمی طولانی شد. تجویز IC87201 این فاصله را به طور معنی داری کاهش داد، در حالی که DXM چنین اثری نداشت. نسبت LF/HF، به عنوان شاخص تعادل سیستم عصبی خودمختار بر عملکرد قلبی، چهل و هشت ساعت پس از ایسکمی افزایش معنی دار یافت. این عدم تعادل چهل و هشت ساعت پس از تزریق هر دو ترکیب IC87201 و DXM بهبود یافت.

    بحث و نتیجه گیری

    نتایج نشان می دهند که ایسکمی مغزی می تواند باعث افزایش فعالیت سیستم سمپاتیک و در پی آن طولانی شدن فاصله QT شود. تجویز IC87201 ممکن است با کاهش این فاصله در بهبود آن موثر باشد؛ بنابراین، IC87201 احتمالا می تواند به عنوان یک گزینه مناسب برای کاهش عوارض قلبی پس از سکته مغزی در نظر گرفته شود.

    Background

    Abnormalities of electrocardiogram and cardiac arrhythmias after stroke are very common. This study investigated the effect of IC87201, a molecule affecting the NMDA receptor intracellular signaling pathway, on reducing QT interval prolongation, as the most common electrocardiogram change after cerebral ischemia, in male rats.

    Materials and Methods

    In this study, 15 male adult rats were randomly divided into three groups: MCAO, MCAO+DXM (dextromethorphan hydrobromide monohydrate, NMDA receptor antagonist), and MCAO+IC87201 (n=5 each). Two hours after ischemia, solvent, DXM, and IC87201 were injected intraperitoneally into these three groups, respectively. Pre-ischemia, four hours, and forty-eight hours post-ischemia neurological-behavioral scores were assessed using the neurological deficit score test. Statistical differences were measured using repeated measures analysis of variance (P<0.05).

    Results

    QT interval significantly prolonged after ischemia. Administration of IC87201 significantly reduced this interval, whereas DXM did not have such an effect. The LF/HF ratio, as an index of autonomic nervous system balance on cardiac performance, significantly increased forty-eight hours after ischemia. This imbalance improved forty-eight hours after the injection of both IC87201 and DXM.

    Conclusion

    The results of this study indicated that cerebral ischemia could lead to an increase in sympathetic activity, which in turn causes prolonged QT interval. The administration of IC87201 may be effective in improving this condition by reducing the QT interval. Therefore, IC87201 may potentially be considered a suitable option for reducing cardiac complications following stroke.

    مطالعه حاضر میزان شیوع انگل های روده ای در افرادی که به بیمارستان های تحت پوشش دانشگاه علوم پزشکی واقع در شهر زاهدان در سال های 1398 تا 1402  مراجعه کرده اند را مورد بررسی قرار داد.

    مواد و روش ها

    مطالعه حاضر توصیفی و به صورت مقطعی صورت گرفته است و شامل 5976 از افرادی هست که با علائم گوارشی به بیمارستان مراجعه کرده اند. برای توصیف داده ها از میانگین (انحراف معیار) و تعداد (درصد) برحسب گروه های مورد مطالعه استفاده گردید.

    یافته ها

    نتایج نشان داد که تعداد  1510 نفر از لحاظ آلودگی مثبت تشخیص داده شدند. بیشترین میزان شیوع آلودگی ها به تک یاخته های روده ای مربوط به ژیاردیا با 528 نفر (8/8 %) و کمترین میزان شیوع مربوط به اندولیماکس نانا با 10 نفر (16/0 %) بود. بیشترین میزان شیوع آلودگی ها به کرم های روده ای مربوط به انتروبیوس ورمیکولاریس با 64 نفر (07/1 %) و کمترین میزان شیوع مربوط به تریکیوریس تریکیورا 19 نفر (31/0 %) بود.

    بحث و نتیجه گیری

    با مقایسه درصد آلودگی در مطالعه اخیر و سایر مطالعات مشابه در سالیان گذشته شیوع بیماری های انگلی روده ای در تمام مناطق کشور به طور قابل ملاحظه ای کاهش یافته است. در عین حال میزان آلودگی به تک یاخته های روده ای به نحو قابل ملاحظه ای بیشتر از کرم های روده ای بود که می تواند به واسطه انتقال مستقیم و ساده تر آن ها نسبت به  انتقال تخم ها و یا لاروهای کرمی باشد.

    Background

    The present study investigated the prevalence of intestinal parasites in individuals who referred to hospitals affiliated with Zahedan University of Medical Sciences, Zahedan, from 2019 to 2023.

    Materials and Methods

    The present descriptive study was conducted cross-sectionally and consisted of 5,976 individuals referring to the hospitals with gastrointestinal. To describe the data, mean (standard deviation) and number (percentage) were used according to the studied groups.

    Results

    The results of the study showed that 1,510 people were diagnosed positive. The highest rate of infection by intestinal protozoa was related to Giardia, affecting 528 people (8.8%), while the lowest rate of infection was related to Endolimax nana, affecting 10 people (0.16%). The highest prevalence rate of infections by intestinal worms was related to Entrobius vermicularis, with 64 people (1.07%), whereas the lowest prevalence rate was associated with Trichuris trichiura, with 19 cases (0.31%). 

    Conclusion

    The comparison of the percentage of pollution in the current study with other relevant studies in the past years showed that the prevalence of intestinal parasitic diseases in this region has decreased significantly, similar to other regions of the country. At the same time, the rate of infection by intestinal protozoa is significantly higher than by intestinal worms. This issue can be due to their direct and easier transmission compared to the worm eggs or larvae.

    The results showed a significant decrease in pain response time at 0.2 doses of Valepotriate in acute and chronic pain phases compared to Formalin (P<0.001). Valepotriate active ingredient also exerted its inhibitory effect on xylene-induced inflammation, with the best inhibition percentage observed for 0.2 mg/kg dose and dexamethasone with extract at 0.2 mg/kg (P<0.01).

    Conclusion

    According to the results, Valepotriate has a relatively strong analgesic effect. It is likely that the mechanism of analgesic action of the extract is at least relatively similar to that of morphine based on opioid receptors. In the inflammation test, the extract was able to inhibit inflammation in a way similar to dexamethasone.

    مقدمه

    نقش پیش بینی کننده شاخص های خونی میانگین حجم پلاکت (MPV) و پهنای توزیع گلبول های قرمز (RDW) در بیماری های قلبی_عروقی ثابت شده است. تمرینات تناوبی با شدت بالا (HIIT) یک روش پایدار و موثر برای بهبود آمادگی قلبی_تنفسی است؛ لذا هدف از پژوهش حاضر بررسی تاثیر 8 هفته HIIT بر MPV ، RDWدر زنان غیرفعال دارای وزن طبیعی و چاق بود.

    مواد و روش ها

    در تحقیق نیمه تجربی از میان جامعه زنان چاق و با وزن طبیعی سالم غیرفعال در دامنه سنی 30 تا 45 سال، 24 نفر انتخاب و در دو گروه آزمایشی 12 نفری (با وزن طبیعی و چاق) قرار گرفتند. هر دو گروه به مدت 8 هفته در یک پروتکل HIIT ایستگاهی، سه جلسه در هفته با شدت 90%Hrmax  شرکت کردند. خونگیری در پیش و پس آزمون پس از 12 ساعت ناشتایی، 48 ساعت پس از آخرین جلسه تمرینی انجام شد. از آزمون آماری تحلیل کوواریانس (ANCOVA) برای تحلیل متغیرها در سطح معناداری 05/0> P استفاده گردید.

    یافته ها

    نتایج این مطالعه نشان داد که بین دو گروه چاق و با وزن طبیعی از نظر متوسط کاهش MPV (045/0=P)، متوسط کاهش RDW (001/0=P) و متوسط افزایش HDL (045/0=P) اختلاف آماری معناداری وجود دارد.

    بحث و نتیجه گیری

    تمرینات با شدت بالا احتمالا باعث تعدیل شاخص MPV و دیگر شاخص های خطر بیماری های قلبی_عروقی مانند شاخص توده بدنی بالا و درصد چربی بدن بالا در زنان میان سال شده و به عنوان یک روش غیردارویی کارآمد، ارزان و در دسترس برای کاهش خطر بیماری های قلبی_عروقی پیشنهاد گردد.

    Background

    The predictive role of mean platelet volume (MPV) and red cell distribution width (RDW) in cardiovascular diseases has been proven. High-intensity interval training (HIIT) is a sustainable and effective method for improving cardiorespiratory fitness. Therefore, the present study aimed to investigate the effect of eight weeks of HIIT on MPV and RDW in inactive, normal-weight, and obese women.

    Materials and Methods

    In this semi-experimental research, 24 participants were voluntarily selected from a population of inactive, healthy, obese women and healthy women of normal weight aged 30 to 45 years. They were divided into two experimental groups, each consisting of 12 participants (normal-weight and obese). Both groups were in a circuit HIIT protocol for eight weeks, three sessions per week with an intensity of 90% HRmax for related exercises. Blood sampling was taken on two occasions: once before and once after a 12-hour fasting period and again 48 hours after the last training session. The analysis of covariance (ANCOVA) statistical test was employed to analyze variables at a significance level of P < 0.05.

    Results

    The results indicated that there was a statistically significant difference between the two obese and normal weight groups in the average decreases in MPV (P=0.045), red blood cell distribution width (RDW) (P=0.001), and high-density lipoprotein (HDL) (P=0.045).

    Conclusion

    High-intensity exercise may modulate MPV and other cardiovascular disease risk factors, such as high body mass index and high body fat percentage in middle-aged women, suggesting an effective, inexpensive, and accessible non-pharmacological method for reducing the risk of cardiovascular diseases.

    Background

    Leptomeningeal carcinomatosis involves the diffuse infiltration of neoplastic cells in the central nervous system, affecting 5-8% of leukemia, breast, and lung cancer cases. Gastric cancer instances are rare, mostly in poorly differentiated adenocarcinomas. We report the first Peruvian case, featuring gastric adenocarcinoma.

    Case Presentation

    A 51-year-old woman presented with severe headache, vomiting, dizziness, blurred vision, tinnitus, bradyphrenia, reduced verbal fluency, sixth cranial nerve paresis, and non-reactive anisocoric pupils. Pleocytosis was found, with positive cytology for metastatic adenocarcinoma in cerebrospinal fluid, and a solid gastric mass defined as poorly differentiated adenocarcinoma. Due to her condition, the patient did not receive oncological management, evolving unfavorably and passing away twenty days later.

    Discussion

    Leptomeningeal carcinomatosis should be considered in patients with advanced cancer and meningeal symptoms. It is more predominant in women, with an average age of 53.84 years. Clinical presentation of leptomeningeal carcinomatosis varies, and diagnosis involves neuroimaging and cerebrospinal fluid cytology. Prognosis is unfavorable, often leading to fatality. Treatment protocols lack standardization, and personalized approaches, including targeted and systemic therapies, are explored for improved outcomes. The exceptional aspect of our case lies in the unique diagnosis of an abdominal tumor following the manifestation of neurological symptoms.

    Conclusion

    It is important to suspect this condition among the causes of meningitis, especially in the presence of an underlying malignancy.

    Background

    Pulmonary alveolar proteinosis (PAP) is a rare disease caused by the accumulation of surfactant in the lung's alveoli, as a result of malfunction in the cleaning function of alveolar macrophages. The major symptoms include cough and dyspnea. Computed tomography scan usually reveals crazy-paving pattern. Lung biopsy confirms the diagnosis by showing accumulations of periodic acid-schiff-positive lipoproteinaceous materials.

    Case Presentation

    In this report, we present a middle-age man with progressive dyspnea on exertion, and frequent cough with no noteworthy medical history. The results of initial examinations and laboratory tests were non-diagnostic, so imaging studies were requested for the patient. After imaging and suspecting PAP as a differential diagnosis due to results of high resolution computed tomography, a transbronchial biopsy was performed to confirm the diagnosis. Then, according to the histopathology reports, the diagnosis of PAP was made. During the biopsy procedure, the patient developed pneumothorax, and accurate treatment approaches were considered for this complication.

    Conclusions

    In patients with chronic progressive dyspnea and cough, appropriate and timely imaging and other paraclinic investigations must be considered by the physicians.

    Background

    Medication errors are a significant cause of adverse events in cancer patients. The study aimed to investigate unintentional medication errors during chemotherapy regimen prescription.

    Methods

    During the six months’ follow-ups, 201 adult patients admitted to outpatients’ chemotherapy ward of Omid Hospital, Isfahan, Iran were examined. An information checklist by the aim of data gathering including patients' demographic information, laboratory data, medications history, chemotherapy drug doses and protocol of administration, pre-medications drugs, and supportive treatment was prepared. The data was compared by standard guidelines and data were presented in percent and frequency.

    Results

    Among the enrolled patients, 327 errors were identified. Sixty-five percent of patients were females and the mean age of patients was 49.2±2.8 years old. Gastrointestinal and breast cancers were among the most frequently reported cancers. The highest frequency of errors (67.27%) was attributed to the prescription of pre-medication drug administration primarily in the management of chemotherapy-induced nausea and vomiting. Medication errors in selection and volume of infused serums (20.18%) and in adjusting the dosage of chemotherapy regimens (10.39%) were the most observed errors. 

    Conclusion

    This study highlighted the important areas to improve cancer management at the medical center. By addressing these challenges and implementing necessary changes, the center can enhance the quality of care provided to cancer patients, ensure adherence to international standards, and improve patient outcomes.

    Background

    Chemotherapy regimens with anthracyclines, widely used in treating breast cancer and lymphoma, are associated with significant cardiac toxicity. While previous studies have primarily focused on left ventricular (LV) function, limited research exists on right ventricular (RV) function. This study aimed to evaluate RV echocardiographic function in breast cancer patients undergoing anthracycline-based chemotherapy.

    Methods

    A cohort of 72 breast cancer patients receiving anthracycline treatment at Ghazi Tabatabai and Madani Hospitals from April to March 2022 participated in this study. Echocardiography was performed before treatment initiation, 15 days after the second chemotherapy session, and 15 days after the final session. Cardiotoxicity levels were calculated using SPSS V22 software with inferential statistical methods, including repeated measures analysis and the Friedman test.

    Results

    RV-free wall strain remained stable 15 days after the second treatment session compared to baseline but showed a statistically significant decrease 15 days after the final session (P = 0.044). The prevalence of abnormal RV-free wall strain increased significantly during the final assessment (P = 0.037). Tumor regression grade (TRG) also demonstrated significant changes over time (P = 0.003). Right ventricular systolic pressure (RVSP) increased significantly throughout the study (P = 0.035), while no significant changes were observed in other parameters such as LVEF, E/E', LAVI, or TAPSE.

    Conclusion

    Anthracycline-based chemotherapy leads to a decline in RV-free wall strain over time, highlighting the importance of monitoring RV function alongside LV function during treatment. Advanced echocardiographic techniques, including strain imaging, may help detect subclinical RV dysfunction earlier.
