As per the goals of the family physician program, it is essential to pay attention to the effectiveness and performance of FPP. Although the implementation of the FPP program is an important development in the discussion of rural health insurance and the provision of health services and referral systems in the country, the evidence suggests that by identifying challenges and taking appropriate action, this plan can be improved. This study aimed to investigate the challenges of rural Family Physician Policy (FPP) in northern Iran. This study comprised a mixed method. The former intended to identify the challenges of rural FFP using the narrative review method. To achieve a comprehensive list of challenges, a narrative review and content analysis were performed and semi‑structured interviews were held with key stakeholders of FPP in the north of Iran, including physicians, managers, and policymakers. Identified challenges were categorized into eight categories including the weakness of the health insurance system, low comprehensiveness of executive guidelines, inappropriate recruitment and maintenance of human resources, weakness of cultural context, low efficacy of health information management system, poor educational effectiveness, inappropriate motivational mechanisms, and weakness of the referral system. As per the quantitative findings, “weakness of the referral system” and “inappropriate recruitment and maintenance of human resources” had the lowest and highest weaknesses, respectively. To address existing challenges in the rural FPP, a comprehensive plan of action should be developed with an emphasis on human resource management, health information management system, comprehensive rural health insurance, and legislation.

The family physician program (FPP) is one of the most significant health care reforms in Iran; however, many studies showed that this program has not been able to achieve its intended objectives because of a variety of challenges. This program, despite the existing challenges, is going to be expanded across the country. To improve the likelihood of its success, identification of the structural and infrastructural challenges is necessary. This systematic review was conducted to assess the structural and infrastructural challenges of FPP in Iran. This systematic review of the literature was conducted in order to investigate the infrastructure and structure needs of the current program in Iran. All published articles related to the FPP in Iran were the subject of this study. The eligibility criteria included original articles, reviews, or case studies published in English or Persian during 2011–2021 related to the challenges in the referral system of FPP in Iran. Data were extracted based on Sample, Phenomenon of Interest, Design, Evaluation, Research type technique and were reported based on the structure of Preferred Reporting Items for Systematic Reviews and Meta‑Analyses. International credible scholarly databases were searched. The search strategy was defined based on keywords and the search syntax. This study identified different challenges of the referral system in the areas associated with legal structure, administration, and social structure. The identified challenges in this program should be addressed in order to ensure that this program will lead to improved quality of care and equity in Iran health care system.

Research has examined the relationship between salivary lactate dehydrogenase (LDH) levels and head and neck squamous cell carcinoma (HNSCC) screening and prognosis. Due to biochemical changes in cancer cells and increased production of lactate products in the body. The present systematic review aims to evaluate the changes in salivary LDH levels in HNSCC patients.

The present study is a systematic review and meta‑analysis. The data were collected by searching PubMed, Science Direct, Scopus, Web of Science, and Google Scholar from 2000 to 2021. The heterogeneity of the articles was analyzed using I2 and TAU2 .

After searching the databases, of 988 articles, 665 duplicated articles were excluded by adopting the inclusion and exclusion criteria. So, 25 articles were primarily selected to be reviewed and evaluated for quality. Finally, 19 articles were selected and analyzed according to the Newcastle–Ottawa checklist. A total of 642 HNSCC patients were reviewed. The meta‑analysis showed salivary LDH levels in the HNSCC group were higher than the control group (mean difference = 0.675, standard error = 0.058) (P < 0.001).

As the research results showed, a significant correlation was observed between salivary LDH levels and HNSCCs. So, LDH can be employed as a valuable and minimally invasive biomarker in head and neck cancer screening and prevention.

In the present study, we investigated the effect of two doses of atropine eye drops versus placebo on myopia progression in children and adolescents.

In this double‑blind, randomized clinical trial, 67 patients aged 6 to 18 years with myopia of ‑2 to ‑6 D were enrolled and randomized to receive a placebo eye drop, atropine 0.1%, or 0.01% ophthalmic solution (one drop per night for 6 months). All participants were followed‑up with for one year after the beginning of the study (at zero, one, three, six, and 12 months) and their spherical equivalent (SE), axial length (AL), anterior chamber depth (ACD), and far and near visual acuity (VA) and the eye drops side effects were recorded. A comparison among the groups was performed using SPSS software, version 24.0.

Spherical equivalent, AL, and ACD decreased and far VA improved in atropine groups to a greater extent than the placebo group (P < .05) at the 6‑month follow‑up. The most common side effects of atropine 0.1% eye drop included photophobia and decreased near VA. At the end of the study (six months after the cessation of atropine), a rebound effect was observed; this effect was especially severe in the 0.1% atropine group.

Atropine eye drops are effective for slowing down and preventing myopia progression. However, without long‑term treatment, they will have a rebound effect. A lower dose (0.01%) is suggested for reducing the side effects and rebound effects.

Ulcerative colitis is one of the major phenotypic forms of inflammatory bowel diseases. The present study aimed to investigate the effect of force swimming exercise on clinical symptoms (disease activity index; DAI), colon histopathology, inflammation and fibrosis, and oxidant/antioxidant balance in dextran sulfate sodium (DSS)‑induced colitis mice.

Male C57BL6 mice were randomly divided into five groups (𝑛 = 6 each): control, exercise, colitis, colitis + sulfasalazine, and colitis + exercise. Exercise was performed by forced swimming six weeks before and during the experiment. Colitis was induced by 1.5% DSS in drinking water. The animals were evaluated for body weight changes and DAI (including changes of body weight, stool consistency, rectal bleeding, and prolapse) during the induction of colitis and treatment. At the end of experiment, colons and spleens were evaluated by H and E and Masson Trichrome stainings. Oxidant (Malon dialdehyde; MDA), and antioxidant markers [total thiol groups, superoxide dismutase (SOD), and catalase activity] were also measured in colon tissue.

Results indicated that exercise in colitis mice significantly improved DAI, colon length, spleen weight, and histological injury score and alleviated fibrotic changes in colon tissue that were comparable to sulfasalazine group. Exercise also restored the oxidant/antioxidant balance in colitis mice by reducing MDA and increasing antioxidative markers including total thiol groups, SOD, and catalase activity.

Taken together, aerobic exercise could improve clinical symptoms and colonic inflammation through, at least, the balancing the oxidative stress markers. Thus, it can be considered in management of colitis patients as effective method.

Sodium arsenate (Na 3As0 4, Sodium As) is an important toxic substance that leads to nephrotoxicity. Due to having bioactive molecules, such as polyphenols and tyrosol, olive oil plays a significant role in scavenging free radicals. This study aimed to investigate the effects of olive oil and tyrosol on As‑induced nephrotoxicity.

In our study, 42 adult male BALB/c mice were randomly divided into six groups: control (normal saline), olive oil (0.4 ml/d, gavage), tyrosol (5 mg/kg/d), Sodium As (15 mg/kg), olive oil + Sodium As, and tyrosol + Sodium As (olive oil and tyrosol received one hour before Sodium As). Drugs were administreted once daily for 30 consecutive days. On the 31st day of the study, oxidative stress parameters in kidney tissue, FRAP in plasma, renal function parameters in serum, and histopathological assays were performed.

Sodium As‑induced renal damage as characterized by a significant increase of creatinine and BUN (P < 0.001) and histopathological changes. Also, Sodium As markedly altered oxidative stress biomarkers such as a significant increase in MDA (P < 0.001) and significantly decreased in FRAP and GSH (P < 0.01). Olive oil and tyrosol administration significantly improved the renal antioxidant defense system and decreased MDA concentration, markedly preserving the tissue structure and functional markers of kidney. However, these effects were more effective for tyrosol than olive oil.

Our results suggest that olive oil and tyrosol can be used as a protective agent in preventing Sodium As‑induced nephrotoxicity due to antioxidant property.

Several animal studies have shown the protective effect of silymarin (the extract of Silybum marianum seeds) against anti‑tuberculosis drug‑induced hepatotoxicity (ATDH). However, the knowledge of ATDH of silymarin in humans is scarce. In this study, we aimed to clinically evaluate it.

During this randomized controlled clinical trial, 36 new cases of tuberculosis (TB) were enrolled to receive either silymarin 150 mg twice daily for two weeks along with a standard anti‑TB therapeutic regimen (experimental group; n = 16) or standard anti‑TB therapeutic regimen alone (control group; n = 21). Liver function tests (serum AST, ALT, ALP, and total bilirubin) at the end of weeks 1 and 2 as well as the rate of ATDH during the study were determined and compared between the groups.

No significant differences between the experimental and control groups were observed at the end of the first week regarding liver function tests; However, at the end of the second week, the mean serum levels of AST (P = 0.03) and ALP (P = 0.04) were significantly lower in the experimental group. ALT (P = 0.016) and ALP (P = 0.027) levels in the experimental group significantly decreased during the study, while the changes in the control group were not significant. Two patients in the control group (9.5%) developed ATDH, while no one in the experimental group manifested this adverse effect.

Our study suggests that silymarin use has the potential for the reduction of anti‑TB drug‑induced hepatotoxicity.

Hematological inflammatory indices are currently suggested to assess systemic inflammation. This study aims to investigate a vitamin D supplementation effect on hematological indices of inflammation in rats.

Forty‑eight middle‑aged male rats were allocated into a normal diet (ND) group (10% fat) and a high‑fat diet (HFD) group (60% fat). The animals were fed for 26 weeks. After this period, each group was randomly divided into three subgroups, each of 8 rats: Group (1): animals were fed the ND and HFD containing 1 IU/g vitamin D for 4 months, group (2): animals were fed the ND and HFD containing 6 IU/g vitamin D for 4 months and group (3): animals were euthanized to evaluate the HFD effect. Serum 25‑hydroxyvitamin D level, white blood cell count (WBCs), platelet count, platelet crit (PCT), mean platelet volume (MPV), platelet distribution width (PDW), platelet‑to‑lymphocyte ratio (PLR), neutrophil‑to‑lymphocyte ratio (NLR), monocyte‑to‑lymphocyte ratio (MLR) were measured.

The HFD, significantly increased body weight, PCT, PDW, PLR, NLR, and MLR and significantly reduced serum vitamin D levels compared to the ND (P < 0.05). There was a significant decrease in food intake, MPV, PDW, and NLR after vitamin D supplementation in the ND‑fed group (P < 0.05). A significant reduction in platelet count, PCT, and MLR was observed after vitamin D supplementation in HFD‑fed rats (P < 0.05).

In our study, some hemogram‑derived inflammatory indices were higher in the HFD‑fed group, and vitamin D supplementation lowering effects on some hematological indices were seen in both ND and HFD groups.

The COVID‑19 pandemic has created several challenges for countries all over the world. Different countries have taken different measures to fight this pandemic and reduce its challenges depending on their cultural, economic, and social structures. This study aims to understand and explain the Iranian health system’s response to fighting the COVID‑19 pandemic from the managers’ and authorities’ perspective.

This study is a basic applied research performed under a qualitative approach. In the survey, 30 experts including the managers of health centers and deputies and heads of the Ministry of Health and Medical Education and Medical Universities were selected by purposive snowball sampling and participated in semi‑structured interviews from March to May 2020. The researchers explained the actions of the Iranian health system in fighting the COVID‑19 pandemic in 2020 by content analysis.

As a result, 14 subthemes were found and classified into four major themes, including the informative and regulative actions (two subthemes), administrative and supportive actions (six subthemes), preventive and curative actions (three subthemes), and resource‑related actions (three subthemes).

Due to its strong health structures, such as urban and rural health networks, various general and specialized hospitals, experienced doctors, and committed health staff, Iran has taken practical actions in fighting the COVID‑19 pandemic. However, the findings of this study and its relevant measures can help combat this pandemic in countries with similar social and cultural structures or counter future similar crises.

This study is to determine the effect of the family‑centered intervention (FCIS) on the key indicators of diabetes management and Control control in patients with type‑2 diabetes.

The present study is a quiz‑ experimental study with a randomized control group. Participants were 64 patients with type‑2 diabetes visiting Ali Asghar Hospital of Isfahan in 2018. The eligible patients were assigned to either the intervention group or the control group (i.e., patient‑center care) through block randomization. FCIS were implemented in 4 two‑hour sessions as home visits while the patients and their caregivers were present. Data were collected twice‑i.e. before the intervention and 12 weeks after it‑ and were analyzed, by running a t‑test (α = 0.05), using SPSS‑21.

The mean ± SD age of participants was 50.4 ± 8.5. There was no significant difference between the two groups in the mean weight, serum levels of FBS and A1C, physical activity, energy intake, and BMI before intervention. But, a significant improvement in the mean values of these variables in the intervention group after the intervention, compared with the control group was indicated (P < 0.05).

This study suggests that FCIS are more effective than patient‑center care in the management and control of type‑2 diabetes. Therefore, it is recommended that the family be considered in educational interventions.

One of the most effective strategies to improve the access of community members to health services is to regionalize health services. The purpose of this study is to examine and prioritize measures that could help to counteract obstacles and problems in implementing the regionalization of healthcare in Iran.

The study relied on a mixed research method, including qualitative and quantitative phases. First, by conducting semi‑structured interviews and analyzing them through qualitative content analysis, the obstacles and measures were identified. In the quantitative phase, the obstacles identified were weighted using the fuzzy best‑worst method (FBWM), and the measures were then prioritized through the fuzzy TOPSIS (FTOPSIS) method.

The obstacles were categorized into four main dimensions: “infrastructural,” “political,” “human resources,” and “managerial.” Among the 15 obstacles identified, “absence of performance guarantees” was the most important obstacle, while “insufficient education” was the least important obstacle to the regionalization of healthcare services in Iran. Meanwhile, the following eight measures that could help to overcome the obstacles were extracted from the interviews: “conducting a needs assessment,” “providing clinical guidelines,” “employing specialized human resources,” “reinforcing the referral system,” and “preparing electronic health records,” “enhancing education and information dissimilation,” “building executive support,” and “providing cost‑effective equipment and technology.” “Employing specialized human resources” was also the most effective measure to overcome the obstacles.

Iranian healthcare policy‑makers can use the empirical findings of this investigation to accelerate the implementation of Iran’s regionalization plan to improve the access of community members to healthcare services.

Each research roves around the P value. A value less than 0.05 is considered to be statistically significant. Very few researchers are aware of the history, real‑world significance, statistical insight, and in‑depth criticism about this monumental alphabet of research. This article will provide detailed insight into the most common molecule of research which will be rewarding for the young students and researchers in the primary world of research. It is not a simple value; it is the longest and broadest description of research squeezed to a number for the ground level worker to the principal investigator. The present review will provide a detailed and unique insight into the P value which would be rewarding for the primary care physicians toward translating research into their clinical practice.

Since the emergence of COVID‑19, governments of the world have adopted diverse measurements for containing its propagation. Airborne transmission is the main route of contagion, and wearing masks and social distancing have been specially considered. Many epidemiology experts, the WHO, local authorities, and social media have strongly advocated such strategies.

Dear Editor, The spread of COVID-19 in December 2019 and the spread of this infection led to a global epidemic, and as of October 26, 2021, more than 243 million confirmed infected cases, and over 4953,246 deaths were reported globally.

Dear Editor, The rapid spread of Covid-19 vaccines has led to distrust and concerns about the safety of vaccines, which has directly increased the general suspicion of vaccine injection.[1] In global health emergencies (such as the COVID-19 epidemic), a more comprehensive range of information sources is often used to inform health-related measures.
