Preeclampsia (PE) is a pregnancy‑related syndrome with moderate mortality. Early diagnosis of the condition remains difficult, with the current diagnostic modalities being ineffective. The varying microRNAs (miRNAs) as a novel biomarker pose an alternative solution with their potential to be reviewed.

This study follows the Preferred Reporting Item for Systematic Review and Meta‑Analysis Extended for Scoping Review (PRISMA‑ScR). PubMed/ MEDLINE, CENTRAL/Cochrane, ProQuest, Science Direct, and Wiley Online Library were used for this review. We only include observational studies. A critical appraisal was assessed in this study using QUADAS‑2.

We retrieved 30 observational studies fulfilling the set criteria. Data extracted were synthesized qualitatively based on miRNAs that are more prominent and their area‑under‑the‑curve (AUC) values. In total, 109 distinct dysregulated miRNAs were identified in comparison to healthy controls, with 10 of them (mir‑518b, mirR‑155, mirR‑155‑5p, miR‑122‑5p, miR‑517‑5p, miR‑520a‑5p, miR‑525‑5p, miR‑320a, miR‑210, and miR‑210‑3p) being identified in two or more studies. A brief look at the results shows that 49 miRNAs are downregulated and 74 miRNAs are upregulated, though the fold change of the dysregulation in all studies is not available due to some studies opting for a visual representation of the differences using whisker plots, bar charts, and heat map diagrams to visualize the difference from the reference control.

This study has analyzed the potential of varying miRNAs as potential diagnostic biomarkers and how they might be used in the future. Despite this, potent miRNAs identified should be more emphasized in future research to determine their applicability and connection with the pathogenesis.

Bisphenol‑S (BPS), as a new human public health concern, was introduced to the plastic industry by BPA‑free labeled products following the restrictions of Bisphenol‑A (BPA) as a safe alternative. However, recent research has revealed a controversial issue. In this regard, the present study aimed to review the relationship between BPS exposure and reproductive system dis/ malfunction.

PubMed and other databases were searched up to January 2021. The standard mean difference (SMD) with a 95% confidence interval (CI) was calculated for the main parameters using the random‑effects model. Finally, 12 studies with 420 subjects were included in this research. Forest plot, meta‑regression, and non‑linear dose‑response effect were calculated for each parameter by random‑effects model.

Based on the results of in vitro assessment, a significant increase was found in the oxidative stress parameters, including superoxide dismutase (SMD: 0.63, 95% CI: 0.321, 0.939), thiobarbituric acid reactive substances (SMD: 0.760, 95% CI: 0.423, 1.096), and reactive oxygen species (SMD: 0.484, 95% CI: 0.132, 0.835). In addition, the hormonal assessment revealed a significant decrease in male testosterone concertation (SMD: ‑0.476, 95% CI: ‑0.881, ‑0.071). Moreover, in vivo examination revealed a significant decrease in hormonal parameters, such as female testosterone (SMD: ‑0.808, 95% CI: ‑1.149, ‑0.467), female estrogen (SMD: ‑2.608, 95% CI: ‑4.588, ‑0.628), female luteinizing hormone (SMD: ‑0.386, 95% CI: ‑0.682, ‑0.089), and female follicle‑stimulating hormone (FSH) (SMD: ‑0.418, 95% CI: ‑0.716, ‑0.119). Besides, linear and non‑linear correlations were detected in the main parameters.

In conclusion, based on the current meta‑analysis, BPS was suggested to be toxic for the reproductive system, similar to the other bisphenols. Moreover, a possible correlation was indicated between oxidative and hormonal status disruption induced by BPS in male and female reproductive systems dis/malfunction.

The aim of the study was to assess the prevalence and correlates of cardiovascular health (CVH) status among adults in Afghanistan.

In a national cross‑sectional household survey 3,447 adults completed CVH measurements in Afghanistan. Criteria for ideal CVH (ICVH) were physical activity, healthy diet, non‑smoking, fasting blood glucose (<100 mg/dL), body mass index (<25 kg/m2 ), total cholesterol (<200 mg/dL), and blood pressure (<120/<80 mmHg).

More than one‑third (34.3%) of participants had 5‑7 ICVH, 45.7% 3‑4 ICVH, and 20% had 0‑2 ICVH. In adjusted logistic regression analysis, secondary or more education (AOR: 1.80, 95% CI: 1.22‑2.66) was positively associated, and older age (45‑69 years) (AOR: 0.33, 95% CI: 0.26‑0.42), and urban residence (AOR: 0.67, 95% CI: 0.51‑0.88) were inversely associated with 5‑7 ICVH.

The prevalence of ICVH was low in Afghan adults. Population measures may be used to improve CVH targeting identified associated factors.

This study aimed to design and evaluate the cooling power of local cooling coats for the head, neck, ankles, and wrists.

Local cooling coatings were designed using Iranians workers’ existing 50th anthropometric percentile data. After immersing the cooling coats in water for 5 minutes, they were placed in a chamber at 30°C, 35°C, and 40°C and 30% and 60% humidity and 0.2‑0.4 m/s air velocity for 120 minutes. The amount of water evaporation was measured by weighing each coat before and after entering the chamber, and then the cooling power of each coat was calculated based on the amount of water evaporation.

The average cooling power of cooling coats with covering areas (two wrists 933.75 cm2 , two ankles 1467.37 cm2 and head and neck 1270 cm2 ) that the total area of the cover is 3671.12 cm2 , i.e., about 20% of the body at 30% relative humidity in 30°C, 35°C and 40°C was 67, 77 and 89 watts, respectively. At the mentioned temperature and in 60% relative humidity, the cooling power was 34, 40, and 55 watts. As the relative humidity increased, the cooling power of the coats decreased.

Local evaporative cooling coat on the head, neck, wrists, and ankles can reasonably repel excess heat entering the body. The best performance of these coats is in hot and dry environments. Probably, if used in conjunction with cooling vests in environments with high temperatures and heavy activity, it can act as a supplement to cooling vests and have a significant effect on improving functions.

Background’:

 India is ranked second in the world in terms of tobacco use and tops the list of eight high‑burden countries that account for two‑thirds of the new tuberculosis (TB) cases globally. As tobacco smoking among TB patients is associated with unsuccessful TB treatment outcomes, effective smoking cessation interventions for TB patients is essential to combat this double pandemic.

The study determined the effectiveness of nicotine replacement therapy (NRT) on smoking reduction and cessation among pulmonary TB patients. Settings and Design: The study included 300 pulmonary TB patients undergoing antitubercular treatment in government health care centers of Dakshina Kannada district in southern India.

The participants in this two‑armed, single‑blinded, placebo‑controlled, block‑randomized trial were divided equally (n = 150) for experimental arm (brief advice + NRT) and control arm (brief advice + placebo). The total duration of treatment and follow‑up was 6 months. Unadjusted relative risk (URR) and adjusted relative risk (ARR) were calculated for treatment outcomes at 95% confidence interval (CI). Generalized linear regression analysis was performed upon variables with P value less than 0.2.

After 6 months of intervention including follow up, there was a significant reduction in self‑reported smoking (ARR = 1.08, 95% CI 1.01–1.17, P = 0.03) in the experimental arm compared with the control arm. Biochemically verified smoking abstinence was not significantly different between the two arms (ARR = 1.01, 95% CI 0.72–1.38, P = 0.97).

The study showed statistically significant effectiveness of NRT for self‑reported smoking reduction.

As a public health emergency, coronavirus disease 2019 (Covid‑19) is a threat to our future; therefore, appropriate health system responsiveness (HSR), as an important criterion, is of crucial importance. This study aimed to evaluate the different dimensions of responsiveness of healthcare centers, both public and private, providing COVID‑19 services in Tehran.

Following a cross‑sectional design, this study was conducted in Tehran (the capital city of I.R. Iran) from May to November 2020. Data were collected using the World Health Organization (WHO) questionnaire on responsiveness. Two hundred questionnaires were filled out through face‑to‑face or phone call interviews in two public and private hospitals (100 in each) providing Covid‑19 services. Participants were selected using the convenience sampling technique among all those who received Covid‑19 services during the past six months in the city of Tehran.

The mean age of participants was 45.9 ± 15.9 and 51.5% were female. On an average, 52.6% of the respondents evaluated at least one dimension of responsiveness as appropriate and/or strongly appropriate. Communication obtained the highest score (58.2%), followed by confidentiality (56.5%), dignity (56%), and prompt attention (52%). Meanwhile, autonomy and choice were evaluated as poor (moderate, weak, and strongly weak) by 63.5 and 52.5% of respondents. There was no significant association between the type of healthcare center (i.e., public or private) and responsiveness (p‑value = 0.896). However, there was a significant difference between gender (p‑value = 0.036) and education level (p‑value = 0.014) with responsiveness. According to the respondents, prompt attention and choice were the most and least important dimensions, respectively.

Evaluation of HSR in the era of COVID‑19 not only provides a tool for qualitative assessment of services but also plays an important role in providing feedback to policymakers to adopt effective policies.

Eye health is essential for quality‑of‑life. The present study aimed to design an eye care behaviors assessment instrument for the student community and evaluate its psychometric properties.

The present mixed‑method cross‑sectional study was conducted in two sections using Creswell and Plano Clark methods for instrument development. The study was conducted in Isfahan, Iran, in 2021. The first section (textual analysis and qualitative research) explained and developed the instrument’s fundamental items. This section included in‑depth, semistructured interviews with 21 students and eight experts. The second section measured the psychometric properties of the instrument. Twenty students assessed the instrument’s qualitative and quantitative face validity in this section. The instrument’s content validity ratio (CVR) and content validity index (CVI) were evaluated. In addition, exploratory factor analysis (performed by 251 students) was used to establish construct validity. Internal and test–retest reliability was determined using Cronbach’s alpha and intraclass correlation coefficients (ICC), respectively.

During face and content validity assessment, a 37‑item questionnaire was finalized. Exploratory factor analysis led to the identification of three factors, including “examinations and glasses‑related behaviors,” “symptom‑related behaviors,” and “screen‑related behaviors.” The three extracted factors accounted for 37.9% of the variance. Cronbach’s alpha was equal to 0.874 when evaluating internal consistency, and the ICC value for the total score of the questionnaire was 0.885 (0.810–0.941), indicating excellent test–retest reliability.

These results demonstrate the questionnaire’s validity and reliability. This instrument assesses the prevalence of university students’ most significant eye health risk behaviors. Consequently, it helps prevent eye problems.

COVID‑19 is a respiratory disease caused by infection with severe acute respiratory syndrome Coronavirus 2 (SARS‑CoV‑2). Thrombotic complications appear to be of particular importance in patients with COVID‑19. This study aimed to investigate Changes in the level of Antiphospholipid antibodies (Anticardiolipin and Anti‑β2‑glycoprotein‑I) and thromboembolic indices in COVID‑19 patients during 3 weeks.

This cross‑sectional study was performed on adults with Covid‑19 hospitalized at Al‑Zahra Hospital in Isfahan. The case group includes the patients admitted to the internal ward or ICU who despite receiving prophylactic or anticoagulant doses suffer from thrombotic complications and the control group includes COVID‑19 patients without thromboembolic events. The sample size of 120 people was considered. Anticardiolipin and anti‑β2‑glycoprotein‑I antibodies, coagulation profiles including Fibrinogen, PTT, PT Troponin, ESR, CRP, and D‑dimer were examined. After collection, the data were entered into spss24 software and analyzed.

The results showed that there was no statistically significant difference in the changes of anticardiolipin and anti‑beta‑2 glycoprotein in IgM and IgG as well as in the changes of ESR, CRP, PTT, PT, and fibrinogen in the two groups (P > 0.05).

Our study showed that there was no statistically significant relationship between anti‑phospholipid antibodies (anticardiolipin and anti‑beta‑2 glycoprotein) and thromboembolic events. Therefore anticardiolipin and anti‑beta‑2 glycoprotein is probably the puzzles causing thrombosis in COVID‑19 patients, and other inflammatory responses should be examined among the cases.

This study aimed at evaluating the accuracy of the pediatric appendicitis scoring method in differentiating nonspecific abdominal pain (NSAP) from appendicitis.

This cross‑sectional study was conducted on 391 children who were hospitalized in the emergency ward due to acute abdominal pain suspected of appendicitis . Pediatric Appendicitis Score (PAS), C-reactive protein (CRP), and appendicitis pathology results of patients undergoing surgery were recorded.

The results showed that the no significant difference was found among patients in the three experimental groups (appendicitis, specific abdominal pain except appendicitis, and NSAP) with respect to temperature (p = 0.212), but the other variables were significantly different. Findings showed that high CRP frequency, pain migration to right lower quadrant (RLQ), tenderness in right iliac fossa (RIF), anorexia, leukocytosis, high neutrophil, and mean tenderness in RLQ in the appendicitis group were higher than those in the other two groups (p = 0.001). The PAS questionnaire can also be used as a reliable questionnaire with appropriate sensitivity (0.929) and specificity (0.993), and this questionnaire along with detailed clinical examinations could reduce the rate of negative appendectomy to less than 1%.

This study showed high accuracy of PAS in diagnosing children with appendicitis and differentiating appendicitis from cases of NSAP and specific abdominal pain other than appendicitis. The PAS system could also significantly reduce cases of negative appendicitis. Although high CRP had an excellent ability to diagnose appendicitis, its accuracy was lower than PAS.

Dear Editor, The World Health Organization, abbreviated as WHO, is one of the United Nations agencies established on April 7, 1948, with the approval of the United Nations General Assembly.[1,2] The WHO is responsible for guiding, coordinating, and promoting the health of the world’s people within the framework of the United Nations. In fact, it provides control, organization, provision of consulting, diagnostic, control, and therapeutic measures and measures to countries around the world.

Dear Editor, According to the WHO, preventive medicine means empowering people to control the determinants of health at three levels of individual, community, and environmental, to achieve complete physical, mental, and social well‑being.[1] Preventive medicine has three components. This includes the following: guiding people to what they need to do to stay healthy, believing that the benefits of prevention outweigh the disadvantages, and finally believing that its recommendations are correct.[2] Preventive medicine aims to eliminate the disease, either by preventing the disease or by stopping the disease and preventing its incidence.[3] COVID‑19 epidemic highlighted the importance of early diagnosis, action, and strengthening of public health systems, of which preventive medicine is one of the most critical tools to address such a need.[4]

Dear Editor, The new coronavirus‑2019 (COVID‑19), which was named by the International Committee on Taxonomy of Viruses as a Severe Acute Respiratory Syndrome Corona Virus 2 (SARS‑CoV‑2),[1] has spread rapidly around the world, and on October 11, 2021, it caused more than 237,383,711 of confirmed cases, over 4,842,716 deaths; this is the largest known pandemic that the world has ever experienced.[2] The disease is rampant around the globe, however, the number of cases and deaths in the developed regions, such as Europe and North America, is excessive, and this raises questions
