RESUMEN
PURPOSE: Cancer survivors may experience a subsequent primary cancer that affects their survival and quality of life. This study aimed to investigate the epidemiology of multiple primary malignant neoplasms (MPMNs) in Kerman province, southeast Iran during 2014-2020. MATERIALS AND METHODS: In this retrospective cohort study, all patients who had been diagnosed with primary cancers and registered with the Kerman Cancer Registry Program (KPBCR) during 2014-2020 were included. MPMNs were defined as primary malignant tumors arising in different sites and/or were of different histological or morphological origins. If the second malignancy was diagnosed within the first six months from the diagnosis of the first tumor it was considered synchronous, and if after six months it was defined as metachronous. Logistic regression was used to analyze the relationship between age, sex, and primary cancer site with incidence and survival of secondary in the entire population. RESULTS: Of 26,315 patients registered with a primary cancer diagnosis, 492 (1.86%) developed subsequent primary cancers. The most common type of secondary cancer was skin and mucosa (n=131, 26.63%) followed by urogenital (n=115, 23.37%), followed by, gastrointestinal (n=62, 14.45%), and breast neoplasms (n=57, 11.59%). Most patients had metachronous tumors (n=350, 71.13%). The primary cancer site (Skin and mucosa, urogenital, and breast) was significantly associated with developing subsequent cancer among cancer survivors. The overall 5-year survival of MPMNs cases was over 50%. Older age at diagnosis (HR= 1.02) and having synchronous tumors (HR=1.41) were negatively associated with the survival time of patients with MPMNs. CONCLUSION: Both patients and physicians should be taught about the importance of prevention and the provision of care and screening services among cancer survivors. Studying the epidemiology, susceptibility, and risk factors of MPMNs among cancer survivors will open windows to a better understanding of this phenomenon and policy making.

OBJECTIVES: Bladder-Sparing Approach was presented in patients who are not willing or not suitable for Radical Cystectomy (RC). There have been inconsistencies in the literature regarding the comparison of survival rates of these two methods. Our objective is to evaluate the survival rate of patients with muscle-invasive bladder cancer (MIBC) undergoing different treatment methods. DESIGN: Retrospective cross-sectional study. SETTING: A secondary care, multicenter study in Kerman, Iran 2008 to 2016. PARTICIPANTS: All 200 patients who were diagnosed with Muscle Invasive Bladder Cancer and were admitted to our hospitals. Patients with inaccessible medical files and patients with pathologies other than TCC were excluded. MAIN OUTCOME MEASURES: Radical cystectomy and different methods of bladder preservation were compared based on their survival rate. INTERVENTIONS: Radical cystectomy or bladder preservation. RESULTS: Overall survival of the patients was 2 years [95% CI: 1.37-2.63]. The overall 5-year survival rate of patients with MIBC was 32%. Having a 6.4 years overall survival, the RC group showed the highest survival compared with others (p = 0.01); the overall survival of patients undergoing TMT, TURT, chemotherapy, or radiotherapy monotherapy was 3.15 years [95% CI: 2.242-4.061], 4.06 [95% CI: 3.207-4.931], 2.58 [95% CI: 1.767-3.399], and 3.14 [95% CI: 1.614-4.672] years, respectively. Patients younger than 65 undergoing RC had an overall survival of 7 years, compared with 2 years for the TMT group. (p = 0.0001). CONCLUSIONS: The Bladder-Preservation method, as a replacement for RC, showed a lower overall survival rate in our study. A prospective randomized clinical trial may declare the best treatment.
RESUMEN
Background: Cervical cancer is the fourth leading cause of cancer-related death among women worldwide. We aimed to identify the factors affecting the survival rate of cervical cancer patients, as these factors are vital for preventing the progression and effective treatment of cancer. Methods: In this retrospective cohort study, 254 patients with cervical cancer who were registered in The Kerman Population-Based Cancer Registry (KPBCR) between 2012 and 2022 and whose status was known to be alive or dead were enrolled. Since the proportional hazard assumption was not established for the type of treatment, the extended Cox model was used to determine the variables influencing the survival of the patients. Results: The mean survival time of the patients was 91.28 ± 3.02 months. The results of fitting the extended Cox model showed that the risk of death increases by 1.02 per year of age at diagnosis (HR=1.02; 95% CI: 1.00, 1.04). Moreover, for a one-unit increase in body mass index (BMI), the risk of death increased by 0.93 (HR=0.93; 95% CI: 0.88, 0.98). The risk of death in patients with disease stages III&IV was 3.08 times that of patients with disease stages I&II (HR=3.08; 95% CI: 1.05, 9.03). The risk of death in patients receiving at least one of the radiotherapy and chemotherapy treatments after 18 months was 7.11 times that of patients undergoing surgery (HR=7.11; 95% CI: 1.69, 29.91). Conclusion: The age of diagnosis, BMI, disease stage, and type of treatment significantly affect the survival of patients. Thus, raising women's awareness of periodical examinations and early diagnosis can reduce the risk of death and prevent cervical cancer progression.
RESUMEN
Background: Obesity has increasingly become a health threat in the Middle East and North Africa (MENA) countries. This study aimed to investigate the scientific publications on obesity in the MENA countries during 2008-2020. Methods: A longitudinal analysis of 13 years (2008-2020) of bibliographic data from obesity-related articles was performed. Web of Science core collection (WoS) was searched for bibliographic data. The bibliometric indicators including overall productivity and collaboration along with the prevalence of obesity and socioeconomic status were used to assess and compare the context of obesity research efforts in the MENA region. Results: The overall obesity-related articles of the MENA countries cumulated to 23680 publications. The MENA region accounted for a 6.5% global publication share in obesity research. Turkey contributed the highest rate of total publications (n=6162) followed by Iran (n=5302) and Israel (n=2847). Iran and Turkey had the lowest rates of international collaborations. The overall obesity research was not significantly associated with socio-demographic index (SDI) measure (r=-0.26, P=0.27). No significant association was found between Gross National Income (GNI) per capita and the overall production of obesity research (r=0.41, P=0.08). Additionally, obesity research was not significantly associated with the prevalence of obesity in the countries (r=0.24, P=0.30). Conclusion: This study observed an increased share of scientific productivity in the field of obesity from the MENA countries. Neither SDI, GNI per capita, nor obesity prevalence was not significantly associated with the overall productivity of the region.
RESUMEN
OBJECTIVE: The COVID-19 pandemic exposed significant gaps in Iran's and other health systems' risk communication. The accompanying infodemic undermined policy responses, amplified distrust in government and reduced adherence to public health recommendations among the Iranian population. This study aimed to develop a conceptual framework for health risk communication and infodemic management (RCIM) during epidemics and health emergencies in Iran that could have potential applications in other contexts. DESIGN: This study was designed in two phases. Phase 1 involved semistructured qualitative interviews with key informants to explore effective RCIM strategies across public health settings in Iran and to develop a conceptual framework. Phase 2 involved revising the framework based on feedback from an online expert panel regarding its comprehensiveness and validity. SETTING: Provincial/national public health settings in Iran. PARTICIPANTS: Twenty key informants from provincial and national public health authorities who contributed to COVID-19 response programmes participated in interviews. Nine experts from diverse academic disciplines, provincial and national settings, and geographical locations participated in an online expert panel. RESULTS: The conceptual model was created based on qualitative interviews and expert panel discussions and was structured according to six pillars of the WHO health system framework: leadership and governance, information, health workforce and financial resources, along with media and community. Leadership and governance, including trustworthy leaders, were recommended as the foundation for developing RCIM in Iran. Developing an official strategy with information infrastructures, including high-quality surveillance systems, identified personnel and training for specialists among the health workforce, financial resources, communication channels and community engagement were recognised as other dimensions for developing health risk communication in Iran. CONCLUSION: The proposed framework represents a step toward establishing a national RCIM strategy in Iran. Further validation of the conceptual framework and experiments on how it could potentially influence policy and practice is recommended. This model has the potential to be applied in other contexts in its current form or as the foundation for customised local versions.

Bladder cancer (BC) is the 10th most common cancer in the world. While there are FDA-approved urinary assays to detect BC, none have demonstrated sufficient sensitivity and specificity to be integrated into clinical practice. Telomerase Reverse Transcriptase (TERT) gene mutations have been identified as the most common BC mutations that could potentially be used as non-invasive urinary biomarkers to detect BC. This study aims to evaluate the validity of these tests to detect BC in the Kerman province of Iran, where BC is the most common cancer in men. Urine samples of 31 patients with primary (n = 11) or recurrent (n = 20) bladder tumor and 50 controls were prospectively collected. Total urinary DNA was screened for the TERT promoter mutations (uTERTpm) by Droplet Digital PCR (ddPCR) assays. The performance characteristics of uTERTpm and the influence by disease stage and grade were compared to urine cytology results. The uTERTpm was 100% sensitive and 88% specific to detect primary BC, while it was 50% sensitive and 88% specific in detecting recurrent BC. The overall sensitivity and specificity of uTERTpm to detect bladder cancer were 67.7% and 88.0%, respectively, which were consistent across different tumor stages and grades. The most frequent uTERTpm mutations among BC cases were C228T (18/31), C250T (4/31), and C158A (1/31) with mutant allelic frequency (MAF) ranging from 0.2% to 63.3%. Urine cytology demonstrated a similar sensitivity (67.7%), but lower specificity (62.0%) than uTERTpm in detecting BC. Combined uTERTpm and urine cytology increased the sensitivity to 83.8%, but decreased the specificity to 52.0%. Our study demonstrated promising diagnostic accuracy for the uTERTpm as a non-invasive urinary biomarker to detect, in particular, primary BC in this population.

BACKGROUND AND AIMS: Violence against pregnant women is a significant public health problem, resulting in disability and various physical and mental health disorders. This systematic review and meta-analysis explored the prevalence of physical, verbal, sexual, psychological, emotional, economic, and other types of violence among pregnant women in Iran. METHODS: Bibliographic databases including PubMed, Embase, Web of Science (WoS), and Scopus, and also Iranian databases including Scientific Information Database (SID), Magiran, and Civilica were searched from 2002 to September 16, 2020. Following a random-effects meta-analysis, we estimated the pooled prevalence of exposure to different types of violence among Iranian pregnant women. Overall, 61 articles that met the inclusion criteria were analyzed in this systematic review. RESULTS: The prevalence of physical violence was 19.0% (95% confidence intervals [CI]: 14.0, 24.0), verbal violence was 42.0% (95% CI: 24.0, 61.0), sexual violence was 26.0% (95% CI: 20.0, 32.0), psychological violence was 37.0% (95% CI: 28.0, 46.0), emotional violence was 51.0% (95% CI: 40.0, 62.0), economic 39.0% (95% CI: 19.0, 60.0), and the prevalence of other types of violence was 54.0% (95% CI: 46.0, 62.0). CONCLUSIONS: This study revealed that Iranian pregnant women are often exposed to different types of violence. Therefore, screening for violence in this vulnerable group seems necessary due to the sensitive nature of pregnancy and its importance in maternal health. This alarming rate of violence calls for adopting upstream policies and interventions to reduce violent practices against pregnant women in Iran.

ABSTRACT: Condomless sex is the most proximal risk for HIV acquisition among female sex workers (FSWs). We performed a systematic review and meta-analysis to summarize the evidence for the prevalence of condomless sex among FSWs in Iran. A random-effect meta-analysis model was used to pool the prevalence estimates and their 95% confidence intervals (CIs). The pooled prevalence of condomless sex at last sex with a paying client and a nonpaying partner was 34.23% (95% CI: 27.83-40.93) and 48.34 (95% CI: 38.43-58.32), respectively. Last-month inconsistent condom use was 49.01% (95% CI: 21.64-76.71) with paying clients and 60.21% (95% CI: 31.27-85.73) with nonpaying partners. The pooled prevalence of lifetime condom nonuse with any partners/clients was 15.26% (95% CI: 10.68-20.49). These findings indicate that a substantial proportion of FSWs engage in high-risk sexual practices. Community-led programs should be stimulated to improve consistent condom use among FSWs.

BACKGROUND: Bladder cancer disproportionally affects the communities. While it is the ninth most common cancer in the world, in some parts of Iran including Kerman province it is the most common cancer among men. This study aimed to determine potential risk factors of bladder cancer in Kerman province, Iran. METHODS: During February to July 2020, in this matched hospital-based case-control study, 100 patients with bladder cancer and 200 healthy individuals (matched in age and sex) were recruited. Socio-demographics status, occupational exposures, common diet, history of drug use and family history of cancer, were collected using a structured questionnaire. Bivariable and multivariable logistic regression were applied and crude and adjusted odds ratios (AOR) along with their 95% confidence intervals (95%CI) were calculated. Data were analyzed using Stata version 14 software. RESULTS: Opium consumption, cigarette smoking and low level of income were associated with increased chance of bladder cancer. Compared to never use, use of opium up to 18000 Gram -year was associated with increased chance of bladder cancer (AOR: 6; 95% CI =2.3, 15.5). The chance was higher among those who used opium more than 18,000 Gram - year (AOR: 11.3; 95% CI =2.3, 15.5). In comparison with never smokers, the chance of bladder cancer increased among those who smoked up to 20 pack-year cigarette) (AOR: 3.4; 95%CI= 1.3, 8.9) and those who smoke ≥ 20 pack-year (AOR: 15.8; 95% CI= 5.9, 42.4). CONCLUSIONS: The observed strong dose-response association between opium consumption, cigarette smoking and bladder cancer highlights the need for extension of harm reduction programs especially in regions with high burden of disease.

There is a lack of conceptual clarity about the role of delivering private hospital services (DPHS) accompanied by major gaps in evidence. The purpose of this systematic scoping review was to identify and map the available evidence regarding the developing countries to scrutinize the participation of DPHS exclusively in the universal health coverage (UHC) through providing graphical/tabular classifications of the bibliometric information, sources of the records, frequent location, contribution of the private hospital services in the health system, and roles of DPHS in UHC. This study was performed following the published methodological guidance of the Joanna Briggs Institute for the conduct of scoping review, applying some major databases and search engines. In addition, a narrative-thematic synthesis integrated with the systematic analysis using the policy framework of the World Health Organization was employed. The 28 included records in English which met the inclusion criteria were found between 2014 and January 2020. The chronological trend of records was progressive until 2019. India was the most frequent location (12%). China and Sri Lanka on the one end of the spectrum and Somalia along with South Korea from the other end were, respectively, the least and the most contributed countries in terms of DPHS. Overall, 90% of the roles were concerned with UHC goals. Although evidence has revealed inconsistency in the identified roles, a continuous chain of positive or negative effects in the UHC objectives and goals was observed. Some knowledge gaps about the roles, causes of the increasing and decreasing DPHS contribution, and its behaviors around the privatization types and circumstances of the delivery were recommended as prioritized research agendas for evidence-based policymaking in future.
RESUMEN
BACKGROUND: Some patients with coronavirus disease 2019 (COVID-19) have been reported to have developed mild to severe kidney injuries. The current systematic review and meta-analysis was carried out to estimate the prevalence and incidence of acute kidney injury (AKI) among COVID-19 patients. STUDY DESIGN: A systematic review and meta-analysis . METHODS: PubMed, Embase, Scopus, Web of Science, and MedRxiv databases were searched from December 1, 2019, up to July 27, 2020. Two independent co-authors completed the screening process, data extraction, and quality assessment of the retrieved records. Random-effects meta-analyses were used to determine the pooled prevalence and 95% confidence interval (CI) of AKI among COVID-19 patients. RESULTS: Out of 2,332 unique identified records, 51 studies were included in the review. Overall, the studies were carried out on 25,600 patients. A total of 6,505 patients (in 18 cross-sectional studies) were included to estimate the pooled prevalence of AKI, and 18,934 patients (in 27 cohort studies) were included to determine the pooled incidence of AKI. The pooled prevalence of AKI was estimated as 10.08% (95% CI: 4.59, 17.32; I2=98.56%; P<0.001). Furthermore, the pooled incidence of AKI was 12.78% (95% CI: 7.38, 19.36; I2=99.27%; P<0.001). The mean (95% CI) values of serum creatinine (SCr), blood urea nitrogen (BUN), potassium, and sodium were 76.10 (69.36, 82.84), 4.60 (4.04, 5.30), 3.94 (3.78, 4.11), and 139.30 (138.26, 140.36) mmol/L, respectively. CONCLUSION: The AKI is a considerable complication among COVID-19 patients and should be screened for on clinical examinations. The BUN, SCr, potassium, and sodium levels were within the normal ranges.

BACKGROUND: Illicit drug use is a prevalent risk behavior among female sex workers (FSWs) as it increases the vulnerability of this marginalized population to negative health outcomes, including HIV infection. This systematic review and meta-analysis aimed to estimate the prevalence of injection and non-injection drug use among FSWs in Iran. METHODS: Systematic searches of PubMed, Embase, Web of Science, Scopus, and PsycINFO (for English records), along with Iranian databases including IranMedex, Iran Psych Magiran, Scientific Information Database, and Irandoc (for Farsi records) were conducted for studies published from inception through to July 2020. We included quantitative studies on injection and non-injection drug use among FSWs. The pooled prevalence and 95% confidence intervals (CI) of recent and lifetime drug injection and non-injection were estimated using random-effects meta-analysis. RESULTS: Of 458 screened records, 19 met the inclusion criteria. The pooled prevalence of recent non-injection drug use and injection drug use was 56.94% (95% CI: 44.68, 68.78) and 5.67% (95% CI: 2.09, 10.73), respectively. Opium (33.00%, 95% CI: 24.53, 42.05) and crystal methamphetamine (20.68%, 95% CI: 13.59, 28.79) were the most prevalent recent non-injection drugs used. Additionally, the pooled prevalence of lifetime non-injection drug use was 76.08% (95% CI: 66.81, 84.27) and injection drug use was 10.72% (95% CI: 7.02, 15.07). CONCLUSIONS: This systematic review shows that drug use, both injection and non-injection, is prevalent among FSWs in Iran. These findings highlight the importance of evidence-based harm reduction and treatment programs to reduce the burdens of drug use and its associated potential consequences among these underserved women.

Several studies have reported the characteristics of Coronavirus disease 2019 (COVID-19), yet there is a gap in our understanding of the ocular manifestations of COVID-19. In this systematic review and meta-analysis, we investigated the prevalence of ocular manifestations in COVID-19 patients. We searched Pubmed, Embase, Scopus, Web of Science, and medRxiv from December 1, 2019 to August 11, 2020. Two independent reviewers screened the articles, abstracted the data, and assessed the quality of included studies in duplicate. Thirty-eight studies were eligible after screening of 895 unique articles, with a total of 8,219 COVID-19 patients (55.3% female; n = 3,486 out of 6,308 patients). Using data extracted from cross-sectional studies, we performed random-effects meta-analyses to estimate the pooled prevalence of ocular symptoms along with 95% confidence interval (CI). The prevalence of ocular manifestations was estimated to be 11.03% (95% CI: 5.71-17.72). In the studies that reported the details of observed ocular symptoms, the most common ocular manifestations were dry eye or foreign body sensation (n = 138, 16%), redness (n = 114, 13.3%), tearing (n = 111, 12.8%), itching (n = 109, 12.6%), eye pain (n = 83, 9.6%) and discharge (n = 76, 8.8%). Moreover, conjunctivitis had the highest rate among reported ocular diseases in COVID-19 patients (79 out of 89, 88.8%). The results suggest that approximately one out of ten COVID-19 patients show at least one ocular symptom. Attention to ocular manifestations, especially conjunctivitis, can increase the sensitivity of COVID-19 detection among patients.
RESUMEN
INTRODUCTION: Disciplinary-based information literacy (DIL) or professional-related information literacy has not been widely studied in the academic context, including medical sciences. This study aimed at investigating the status of DIL among medical students in an Iranian medical university. MATERIALS AND METHODS: This study was a cross-sectional survey. A random sample consisting of 298 students majoring in general medicine at Tehran University of Medical Science, Tehran, Iran, in the academic year of 2018-2019 completed a valid and reliable 20-item questionnaire on DIL. Data were analyzed using SPSS statistical software. RESULTS: Participants' DIL was less than expected, especially in the skills related to professional information access and evaluation. The majority of them had low DIL level. However, medical students in their last 2 years of study had significantly high scores in DIL than those in their first 2 years of study. CONCLUSION: Information literacy has not been seriously considered in health-related higher education in Iran. It is needed to consider DIL in the medical curriculum for training students to be proficient specialists in medical practice.
RESUMEN
BACKGROUND: With the growing rate of tumors, cancer has become one of the most important health concerns in Iran. The urgency with which Iranian researchers and health professionals address this challenge leads to a load of scientific materials. METHODS: To reveal gaps in produced knowledge and suggest future research directions, applying well-validated scientometric tools, we assessed the trends of Iranian published scientific articles and citations in the field of oncology. The inclusion criteria consisted of all oncology-related articles that were data-based, and peer-reviewed; with at least an abstract published in English; and authored by at least one researcher affiliated with Iranian institutions. RESULTS: Amongst 5063525 oncology research records indexed in at least one of PubMed, Scopus, or Web of Science Core Collection (WoS) from the start to February 2019, Iranian researches accounted for about 24867 (0.49%). Published articles on all cancers by Iranian researchers had a sharp continuously ascending trend, with the same pattern for citations received. Some important topics such as complementary and alternative medicine (CAM) therapies have been missing and some such as diagnostic and pharmaceutical innovations have been less investigated. The most collaborative country was the United States, while no close collaboration was observed with China that was introduced as the most productive country in the field of oncology over the past decades. CONCLUSION: Despite the progressive trend in most oncology fields, some significant practical topics are still missing. Systematic reviews of produced theoretical innovations and translating them to functional knowledge can be of importance to fulfill the mentioned gaps.

Introduction: The epidemiology of common cancers in Kerman province, southeast of Iran, was assessed based upon results of the Kerman Population-Based Cancer Registry Program (KPBCR). Methods: in this retrospective study, all patients diagnosed with primary cancers and registered with the KPBCR were included. New cancer cases registered from 2014 were identified from pathological labs, medical reports of 48 health facilities providing cancer diagnosis or treatment services and the national death registry program. Data for patients who were referred to neighboring provinces to access health services were also collected from national referral registries. Results from autopsies was additionally extracted from regional forensic and legal medicine centers and added to the registry periodically. Age standardized incidence rates (ASRs) per 100,000 person-years for all cancers were computed, using direct-standardization and CanReg methodology. Mortality to incidence (M:I) ratios and microscopically verified (MV) proportions were calculated as quality measures. Results: A total of 2,838 cases of cancer were registered in Kerman province, 2014. Of these 45. 6% involved women (n=1,293). Individuals aged 60-64 years represented the largest proportion (11.6%) of the total cancer prevalence, followed by those aged 55-59 years (10.86%) and 65-69 years (8.99%). The ASRs for all cancers were 155.1 and 118.90 per 100,000, in men and women, respectively. In women, breast (ASR: 26.4), skin (ASR: 13.0), thyroid (ASR: 9.2), leukemia (ASR: 8.0) and colorectal (ASR: 7.70) were the most common cancers. In men, bladder (ASR: 24.70), skin (ASR: 16.80), lung (ASR: 14.6), leukemia (ASR: 14.50), and stomach (ASR: 10.8) were found to be the most frequent. Conclusion: This study provided latest evidence on epidemiology of cancer in the southeast of Iran that could be used to empower prevention and control interventions in a developing country.

Probiotics are considered as -immunomodulatory agents; their efficacy as an adjunct therapy option for rheumatoid arthritis (RA), however, remains controversial. The main aim of the present meta-analysis, therefore, was to compare available data from the published randomized, controlled trials (RCTs) recruiting adults with RA which compared probiotics with placebo. The English literature search was performed using Ovid version of Medline, EmBase, Web of Science, and the Central Cochrane library through October 2016 and supplemented by hand searching reference lists. Among 240 citations identified, 4 RCTs (153 participants; 89% female) were included. All data were pooled using a standardized mean difference (SMD) with a 95% CI. Compared to the placebo, probiotics did not change the inflammatory parameters (erythrocyte sedimentation rate, tumor necrosis factor [TNF]-α, interleukin [IL]-1ß, IL-6, IL-10, and IL-12) and oxidative stress indices (total antioxidant capacity and malondialdehyde) significantly. The borderline significant reduction as a result of probiotic administration was only determined in C-reactive protein [SDM - 0.32 (95% CI - 0.65 to 0.00)]. Among disease activity indices (disease activity score [DAS], tender joint count, and swollen joint count), DAS showed a significant improvement following probiotic treatment with a SMD (95% CI) of - 0.58 (- 0.97 to - 0.19). The number of trials was too small to determine if a strain-, dose-, or duration-response effect was present. Probiotics seem to be less effective in RA; however, to reach a firm conclusion, we need further evidence.

BACKGROUND: Schizophrenia is a chronic, disabling and severe mental disorder, characterised by disturbance in perception, thought, language, affect and motor behaviour. Chlorpromazine and clotiapine are among antipsychotic drugs used for the treatment of people with schizophrenia. OBJECTIVES: To determine the clinical effects, safety and cost-effectiveness of chlorpromazine compared with clotiapine for adults with schizophrenia. SEARCH METHODS: We searched Cochrane Schizophrenia's Trials Register (last update search 16/01/2016), which is based on regular searches of CINAHL, BIOSIS, AMED, Embase, PubMed, MEDLINE, PsycINFO and clinical trials registries. There are no language, date, document type, or publication status limitations for inclusion of records in the Register. SELECTION CRITERIA: All randomised clinical trials focusing on chlorpromazine versus clotiapine for schizophrenia. We included trials meeting our selection criteria and reporting useable data. DATA COLLECTION AND ANALYSIS: We extracted data independently. For binary outcomes, we calculated risk ratio (RR) and its 95% confidence interval (CI), on an intention-to-treat basis. For continuous data, we estimated the mean difference (MD) between groups and its 95% CI. We employed a random-effects model for analyses. We assessed risk of bias for included studies and created a 'Summary of findings' table using GRADE. MAIN RESULTS: We have included four studies, published between 1974 and 2003, randomising 276 people with schizophrenia to receive either chlorpromazine or clotiapine. The studies were poor at concealing allocation of treatment and blinding of outcome assessment. Our main outcomes of interest were clinically important change in global and mental state, specific change in negative symptoms, incidence of movement disorder (dyskinesia), leaving the study early for any reason, and costs. All reported data were short-term (under six months' follow-up).The trials did not report data for the important outcomes of clinically important change in global or mental state, or cost of care. Improvement in mental state was reported using the Positive and Negative Syndrome Scale (PANSS). When chlorpromazine was compared with clotiapine the average improvement scores for mental state using the PANSS total was higher in the clotiapine group (1 RCT, N = 31, MD 11.50 95% CI 9.42 to 13.58, very low-quality evidence). The average change scores on the PANSS negative sub-scale were similar between treatment groups (1 RCT, N = 21, MD -0.97 95% CI -2.76 to 0.82, very low-quality evidence). There was no clear difference in incidence of dyskinesia (1 RCT, N = 68, RR 3.00 95% CI 0.13 to 71.15, very low-quality evidence). Similar numbers of participants left the study early from each treatment group (3 RCTs, N = 158, RR 0.68 95% CI 0.24 to 1.88, very low-quality evidence). AUTHORS' CONCLUSIONS: Clinically important changes in global and mental state were not reported. Only one trial reported the average change in overall mental state; results favour clotiapine but these limited data are very difficult to trust due to methodological limitations of the study. The comparative effectiveness of chlorpromazine compared to clotiapine on change in global state remains unanswered. Results in this review suggest chlorpromazine and clotiapine cause similar adverse effects, although again, the quality of evidence for this is poor, making firm conclusions difficult.

BACKGROUND: Chlorpromazine, a widely available and inexpensive antipsychotic drug, is considered the benchmark treatment for schizophrenia worldwide. Metiapine, a dibenzothiazepine derivative, has been reported to have potent antipsychotic characteristics. However, no evidence currently exists on the effectiveness of chlorpromazine in treatment of people with schizophrenia compared to metiapine, a newer antipsychotic. OBJECTIVES: To compare the effect of chlorpromazine versus metiapine for the treatment of people with schizophrenia SEARCH METHODS: We searched the Cochrane Schizophrenia Group's Study-Based Register of Trials in November 2015 and 2016. SELECTION CRITERIA: All randomised controlled trials (RCTs) focusing on chlorpromazine versus metiapine for adults with schizophrenia. We included trials meeting our selection criteria and reporting useable data. DATA COLLECTION AND ANALYSIS: We extracted data independently. For binary outcomes, we calculated risk ratio (RR) and its 95% confidence interval (CI), on an intention-to-treat basis. For continuous data, we estimated the mean difference between groups and its 95% CI. We employed a random-effects model for analyses. We assessed risk of bias for included studies and created 'Summary of findings' tables using GRADE. MAIN RESULTS: We included three studies randomising 161 people with schizophrenia. Data were available for only two of our seven prestated main outcomes. Clinically important improvement in global state was measured using the Clinical Global Impression (CGI). There was no clear difference between chlorpromazine and metiapine groups (2 RCTs, n = 120, RR 1.11, 95% CI 0.84 to 1.47, very low quality evidence) and numbers of participants with parkinsonism at eight weeks were similar (2 RCTs, n = 70, RR 0.97, 95% CI 0.46 to 2.03, very low quality evidence). There were no useable data available for the other key outcomes of clinically important improvement in mental state, readmission due to relapse, satisfaction with treatment, aggressive or violent behaviour, or cost of care. AUTHORS' CONCLUSIONS: Chlorpromazine has been the mainstay treatment for schizophrenia for decades, yet available evidence comparing this drug to metiapine fails to provide high-quality trial based data. However, the need to determine whether metiapine is more or less effective than chlorpromazine seems to be lacking in clinical relevance and future research on this comparison seems unlikely.

BACKGROUND: Fracture repair is a complex process. An inappropriate diet is a contributing risk factor for fracture nonunion. The aim of this study was to extract dietary recommendations for fracture healing according to traditional Persian medicine (TPM) literature. METHOD: The contents relevant to diets in fracture healing were selected from main textbooks in TPM like Al Qanon fi Al-teb ( The Canon). Other reference textbooks in traditional medicine were also used for a comprehensive study in this respect. Finally content analysis was used for summarizing and describing the results. FINDINGS: Food stuffs are classified in TPM according to their nutritive value, their assimilability, and the quality of achieved chyme. Some light meals like chicken soup are recommended for the early days of fracture and high-nutrient and dense foods such as goat's or sheep's head and nuts are advised in following days for fracture healing acceleration and callus formation. Several recommendations are also provided for pacing the healing process. CONCLUSION: A comparison of Avicenna and other Persian sage's recommended regimens with the recent evidence revealed the potential positive effects of their regimen for bone healing acceleration. It can shed light on a part of history of orthopedics and add to current knowledge about bone fracture and its management.
