Components related to ethical decision making in medical science students: A structural equation model.

BACKGROUND: Evaluating moral principles in the Society of Medical Sciences and health care workers (HCWs) is imperative due to their direct contact with the community and the significant impact of their attitudes and decisions on people's lives. This study aimed to determine the components related to ethical decisions in medical sciences students. METHODS: One thousand two hundred thirty-five eligible students in the Alborz University of Medical Sciences participated in this descriptive study. We gathered their socio-demographic information, assessed their moral reasoning, and used the ethical decisions questionnaire, Lutsen moral sensitivity questionnaire, and general health questionnaire (GHQ) for data gathering. The data were analyzed with SPSS software version 25 and LISREL version 8.8. RESULTS: According to the path analysis test findings, ethical reasoning significantly correlated with ethical decision-making (B = 0.40). The number of clinical courses passed, moral sensation (moral sensitivity), and the total number of passed academic semesters had the greatest positive and negative association with ethical decision-making, respectively. (B = 0.54), (B = 0.524) and (B = -0.11). CONCLUSION: Based on the findings of the moral reasoning test, the moral sensation was associated with ethical decision-making, which indicates the necessity of attending to ethical aspects, promoting moral reasoning, sensitivity, and students' accuracy.

Determination of molecular epidemiologic pattern of human T-lymphotropic virus type 1 (HTLV-1) in Alborz province, Iran.

Human T-cell lymphotropic virus type 1 (HTLV-1) is linked to two debilitating diseases, adult T-cell leukemia/lymphoma (ATLL) and HTLV-1 associated myelopathy tropical spastic paraparesis (HAM/TSP), which are prevalent in various parts of the world, including the Alborz province in Iran. Understanding the prevalence and evolutionary relationships of HTLV-1 infections in these endemic areas is of utmost importance. In the realm of phylogenetic studies, long terminal repeat (LTR) region of HTLV-1 stands out as highly conserved, yet more variable compared to other gene segments. Consequently, it is the primary focus for phylogenetic analyses. Additionally, trans-activator of transcription (Tax), an oncoprotein, holds a pivotal role in the regulation of gene expression. This cross-sectional study delved into the phylogenetic analysis of HTLV-1 among individuals in Alborz province of Iran. To confirm infection, we amplified partial sequence LTR (PLTR) and HTLV-1 bZIP factor (PHBZ). For phylogenetic analysis, we sequenced the full sequence LTR (FLTR) and full Tax sequence (FTax). The FLTR and FTax sequences underwent analysis using BioEdit, and phylogenetic trees were constructed using MEGA-X software. Out of the roughly 15,000 annual blood donors in Alborz, 19 samples tested positive for HTLV-1, indicating a 0.13% HTLV-1 positivity rate among blood donors. Furthermore, the HTLV-1 virus prevalent in the Alborz province belongs to subtype A (cosmopolitan) subgroup A. The findings revealed that while mutations were observed in both the LTR and Tax genes, they were not significant enough to bring about fundamental alterations. Despite positive selection detected in three Alborz isolates, it has not led to mutations affecting Tax function and virulence.

Oral Lactobacillus species and their probiotic capabilities in patients with periodontitis and periodontally healthy individuals.

OBJECTIVES: This study aimed to identify oral Lactobacillus species and characterize their adhesion properties and antibacterial activity in patients with periodontitis compared with periodontally healthy individuals. MATERIALS AND METHODS: Three hundred and fifty-four isolates from the saliva, subgingival, and tongue plaque of 59 periodontitis patients and 59 healthy individuals were analyzed. Oral Lactobacillus species were identified through the culture method in the modified MRS medium and confirmed by molecular testing. Moreover, the radial diffusion assay and cell culture methods were used to determine the antibacterial activities of oral strains against oral pathogens and their adhesion activity in vitro. RESULTS: 67.7% of the cases and 75.7% of the control samples were positive for the Lactobacillus species. Lacticaseibacillus paracasei and Limosilactobacillus fermentum were the dominant species in the case group, whereas Lacticaseibacillus casei and Lactiplantibacillus plantarum were dominant in the control group. Lactobacillus crispatus and Lactobacillus gasseri had higher antibacterial effects against oral pathogens. Moreover, Ligilactobacillus salivarius and L. fermentum demonstrated the highest ability to adhere to oral mucosal cells and salivary-coated hydroxyapatite. CONCLUSION: L. crispatus, L. gasseri, L. fermentum, and L. salivarius can be introduced as probiotic candidates since they demonstrated appropriate adherence to oral mucosal cells and salivary-coated hydroxyapatite and also antibacterial activities. However, further studies should be conducted to assess the safety of probiotic interventions using these strains in patients with periodontal disease.

Prescribing pattern of antibiotics by family physicians in primary health care.

PURPOSE: Irrational prescription of antibiotics is an ongoing global public health concern, leading to antibiotic resistance. Understanding the prescribing pattern of antibiotics is important to tackling mal-prescription and antibiotic resistance. We aimed to investigate the pattern and factors affecting outpatients' antibiotic prescribing by family physicians in Primary Health Care (PHC). METHODS: A cross-sectional study was conducted in 19 PHC facilities in Alborz province. Prescribing pattern of antibiotics was evaluated among 1068 prescriptions by family physicians. Prescribing pattern of antibiotics included prescriptions containing antibiotics, the number of antibiotics per prescription, type, name of antibiotic, and mal-prescription. Multiple logistic regression analysis was used to estimate the adjusted odds ratios and 95% confidence intervals. RESULTS: Overall, 57% of the prescriptions had ≥ 1 antibiotic and the average number of antibiotics per prescription was 1.27. Amoxicillin was the commonly prescribed antibiotic. There was a significant relationship between age, sex, type of health insurance, work experience of the physician, and seasons with antibiotic prescribing (P < 0.05). In 59.31% of antibiotic prescriptions at least one of the scientific criteria was not fulfilled. In the final analysis, after adjusting for the potential confounders, field experts of physicians (OR = 1.59; 95% CI: 1.08-6.17), female sex (OR = 2.23; 95% CI: 1.18-4.21), and winter season (OR = 3.34; 95% CI: 1.26-8.15) were found associated factors with antibiotic prescribing. CONCLUSION: The average number of antibiotics per prescription and the percentage of irrational prescriptions were relatively high in this study. There is need to improve antibiotic prescribing patterns among family physicians working in primary health care.

The Effectiveness of Auriculotherapy on Women's Sexual Function: A Randomized Controlled Trial.

Objective: Majority of breastfeeding women experience changes in sexual function. The present study was designed to assess effectiveness of auriculotherapy on improving sexual function in breastfeeding women. Method : In this randomized sham controlled trial, accomplished from January 2018 to May 2019 in a referral sexual health clinic in city of Qom, Iran, 60 eligible participants were assigned to either intervention and control groups via block randomization. In the intervention group, electrical stimulation was applied for 15 seconds on Shen Men, Zero, Thalamic, Master Cerebral, Libido, Relax, Excitement, Ovary, and Uterus points in 10 auriculotherapy sessions. Then, Vaccaria seeds were stuck on these points. The control group received the same procedure with the device off as a sham method. Data were gathered using the Female Sexual Function Index (FSFI) at three different time points. Results: At baseline, mean scores of sexual function dimensions were not significantly different between the intervention and control groups except for orgasm. Post-intervention, the results showed significant differences in sexual desire (P = 0.002), sexual arousal (P = 0.008), lubrication (P = 0.001), sexual satisfaction (P = 0.001), and orgasm (P = 0.009). One month after the intervention, the results showed significant differences in sexual desire, sexual arousal, lubrication, sexual satisfaction (P = 0.001), orgasm (P = 0.006), and dyspareunia (P = 0.015). Differences in mean score of sexual function in post-intervention and one-month follow-up were only significant in the intervention group (P = 0.001). Conclusion: Based on evidence from this study, auriculotherapy is an effective technique for improving sexual function in breastfeeding women.

The effectiveness of Jacobson's progressive muscle relaxation technique on maternal, fetal and neonatal outcomes in women with non-severe preeclampsia: a randomized clinical trial.

Background: Preeclampsia (PE), as the most common major pregnancy disorder, has serious maternal, fetal and neonatal complications, and outcomes. The present study was designed to determine the effectiveness of Jacobson's progressive muscle relaxation technique on maternal, fetal, and neonatal outcomes in women with non-severe preeclampsia (PE). Methods: This is a randomized clinical trial conducted from March 21, 2021 to July 22, 2021 in the Kamali referral center in Karaj, Iran. A total of 88 eligible participants were assigned to intervention and control groups (44 in each group) via blocked randomization. The intervention group (6 groups of 6 participants and one group of 8 participants) received Jacobson's progressive muscle relaxation technique in addition to receiving routine care, twice a week for 6 weeks (4 face-to-face sessions and 8 online sessions). The control group only received routine perinatal care. A checklist collected data before and after the intervention. Data were analyzed in SPSS software v.23. To analyze the obtained data, independent t-test, Paired t-test, Mann-Whitney, Chi-square, and Fisher test were used. Results: The results showed a statistically significant difference between intervention and control groups in terms of Systolic Blood pressure (SBP) (P < 0.001), Diastolic Blood pressure (DBP) (P < 0.001), 24-hour urine protein level (proteinuria) (P < 0.001). and Fasting Blood Sugar (FBS) (P < 0.001), birth Weight (BW) (P = 0.01), baseline Fetal heart rate (BFHR) (P < 0.001) and Number fetal movements based on non-stress test (NFMsN), during 20 min (P < 0.001) after intervention (P < 0.001).Also In the intervention group, the results showed a statistically significant difference in Amniotic Fluid Index (AFI) (P = 0.01), SBP(P < 0.001), DBP(P < 0.001), proteinuria (P < 0.001), FBS(P < 0.001), BFHR based on non-stress test (NST) (P < 0.001), and NFMsN during 20 min (P < 0.001) in the intervention group before and after the intervention. There was no statistically significant difference in the control group. Conclusion: This study's results showed the effectiveness of progressive muscle relaxation technique on the improvement of SBP, DBP, proteinuria, FBS, FHR and NFMsN during 20 min based on NST and BW in women with non-severe PE. Therefore, it is recommended to perform this technique in health centers.

The effect of a tele-educational intervention on modifying dysfunctional sexual beliefs of pregnant women: a randomized controlled trial.

BACKGROUND & AIM: Some cultural scenarios in pregnancy and childbirth reinforce dysfunctional sexual beliefs that reverse changes in the couple's sexual life. The present study aimed to investigate the effect of education by sending text messages on modifying dysfunctional sexual beliefs in pregnant women. METHODS & MATERIALS: This study is a randomized clinical trial, and 82 eligible pregnant women referred to educational-medical centers to receive prenatal care were randomly assigned to intervention or control group. The intervention group received 24 text messages during eight weeks (three text messages per week), and the control group received only routine care. Data was collected through a demographic questionnaire, reproductive profile, Spinner's Dyadic Adjustment Scale (DAS), and dysfunctional sexual beliefs questionnaire. Both groups completed the questionnaires before and one week after the intervention. Independent t-test, paired t-test, and analysis of covariance was used to analyze the data. RESULTS: The findings revealed no statistically significant difference in the baseline Dyadic Adjustment mean scores of control (132.4 ± 11.01) and intervention (130.10 ± 10.66) groups. Paired t-test analysis showed that the mean score of dysfunctional sexual beliefs was significantly decreased from (29 ± 7.61) at baseline compared to one week after intervention (10.54 ± 6.97) (p < 0.001). Analysis of covariance test to compare the scores of dysfunctional sexual beliefs in the intervention group (10.54 ± 6.97) and control group (26.80 ± 7.80) showed a statistically significant difference (p < 0.01) with an effect size of 0.67. CONCLUSION: This study showed that sending text messages to mobile phones of pregnant women has corrected their dysfunctional sexual beliefs. Therefore, this approach can be used in pregnancy care to promote women's sexual health. TRIAL REGISTRATION: Clinical trial registry: IRCT20161230031662N9 .

Comparative study of CNR1 and CNR2 cannabinoid receptors expression levels in COVID-19 patients with and without diabetes mellitus: Recommendations for future research targets.

BACKGROUND AND AIMS: The COVID-19 pandemic has prompted researchers to look for effective therapeutic targets. The effect of endocannabinoid system against infectious diseases is investigated for several years. In this study, we evaluated the expression level of CNR1 and CNR2 genes in patients with COVID-19 with and without diabetes to provide new insights regarding these receptors and their potential effect in COVID-19 disease. METHODS: In this study, peripheral blood monocytes cells (PBMCs) were isolated from eight different groups including COVID-19 patients, diabetic patients, and healthy individuals. RNA were extracted to evaluate the expression level of CNR1 and CNR2 genes using real-time PCR. The correlation between the expression levels of these genes in different groups were assessed. RESULTS: A total of 80 samples were divided into 8 groups, with each group consisting of ten samples. When comparing severe and moderate COVID-19 groups to healthy control group, the expression levels of the CNR1 and CNR2 genes were significantly higher in the severe and moderate COVID-19 groups. There were no significant differences between the mild COVID-19 group and the healthy control group. It was found that the expression levels of these genes in patients with diabetes who were infected with SARS-COV-2 did not differ across COVID-19 groups with varying severity, but they were significantly higher when compared to healthy controls. CONCLUSION: Our study suggests the possible role of endocannabinoid system during SARS-COV-2 pathogenicity as the expression of CNR1 and CNR2 were elevated during the disease.

Tele-counseling based on motivational interviewing to change sexual behavior of women living with HIV: a randomized controlled clinical trial.

Sexual transmission accounts for the majority of new HIV infections in Iran. More than 80% of HIV-positive persons are sexually active, and nearly 68% reported never using a condom. The present RCT study was conducted on a group of HIV-positive women using internet-based motivational interviewing. The participants, including 100 HIV-positive women, were randomly assigned to an intervention or control group. The intervention group received five weekly internet-based group motivational interviewing sessions focused on reducing risky behaviors, and the control group received routine care. Follow-ups occurred one month and three months after the end of the intervention. The participants completed demographic information, sexual behaviors, HIV knowledge, condom negotiation skills, and HIV-specific perceived social support scales before, one month, and three months after the intervention. Motivational interviewing was effective in improving knowledge about HIV/AIDS, condom negotiation skills, and HIV-specific perceived social support in the intervention group compared to controls. The intervention significantly increased using condoms in vaginal or anal intercourse in the last three months. Still, it was not effective at consistent condom use in all vaginal and anal sex. Further investigation or a larger RCT needs to confirm the using tele-counseling for women living with HIV.

Contribution of obesity and cardiometabolic risk factors in developing cardiovascular disease: a population-based cohort study.

This study aims to assess the effects of central and general adiposity on development of cardiovascular diseases (CVDs) mediated by cardiometabolic risk factors and to analyze their degree of dependency for mediating their effects. To this end, data from the the Tehran Lipid and Glucose Study cohort with 6280 participants were included in this study. The hazard ratios were calculated using a 2-stage regression model in the context of a survival model. Systolic blood pressure (BP), total serum cholesterol, and fasting plasma glucose were designated as mediators. Assessing the interactions revealed that BP was the most important mediator for general ( (HRNIE: 1.11, 95% CI 1.17-1.24) and central obesity (CO) (HRNIE: 1.11, 95% CI 1.07-1.15) with 60% and 36% proportion of the effects mediated in the total population, respectively. The proportion of mediated risk for all three metabolic risk factors was 46% (95% CI 31-75%) for overweight, 66% (45-100%) for general obesity and 52% (39-87%) for central obesity. BP was the most important mediator for overweight and central obesity in men, comprising 29% and 36% of the risk, respectively. The proportion of the risk mediated through all three metabolic risk factors in women was 23% (95% CI 13-50%) for overweight, 36% (21-64%) for general obesity and 52% (39-87%) for central obesity. Based on the results of this study, cardiometabolic mediators have conciliated more than 60% of the adverse effects of high BMI on CVDs in men. Controlling the metabolic risk factors in women does not efficiently contribute to decreasing CVDs as effectively.

Comparison of an ephedrine infusion with lidocaine %5 for prevention of hypotension during spinal anesthesia in cesarean section.

BACKGROUND: Spinal anesthesia is the method of choice for cesarean section and in most cases causes hypotension. OBJECTIVE: The aim of this study was to treat hypotension by ephedrine in order to prevent maternal and fetal complications, and also to determine the effective amount of ephedrine for reducing arterial hypertension in order to prevent its complications, including cardiac arrhythmias. METHOD: This cross-sectional descriptive study was conducted on 131 patients. Mean arterial blood pressure (MAP) of the candidates for cesarean section in the supine position was measured and recorded as mean baseline blood pressure. 75 mg of lidocaine (5%) was used as spinal anesthesia, following which the average blood pressure was measured every 1 min. In the event of a decrease in the mean arterial blood pressure of at least 20% of the mean baseline blood pressure, ephedrine 0.1/mg/kg was injected intravenously and after 1 min of MAP was measured. RESULT: The prevalence of hypotension was 89.30%. 25.60% of patients with hypotension had 30-34.99% reduction in MAP compared to baseline MAP. 12% patients had 40% drop in their MAP. 4 min following spinal anesthesia, the incidence of hypotension reduced by 20%. The average dose of ephedrine required to reduce the incidence of hypotension was 20.5 mg. CONCLUSION: Reduction in MAP following spinal anesthesia using lidocaine is common. Ephedrine at the dose of 20 mg is effective to reduce the incidence of perioperative hypotension.

Comparison of echocardiographic findings in women with late preeclampsia and healthy pregnant women: a case-control study.

BACKGROUND: Preeclampsia is one of the most common types of pregnancy disorders, and it is essential to know its cardiovascular complications. Therefore, we aimed to compare echocardiographic findings in women with late preeclampsia and healthy pregnant women. METHOD: In this case-control study, 80 women with late preeclampsia and 80 healthy pregnant women were randomly selected and echocardiographic findings were determined and compared in the two groups. RESULTS: Evaluating the relationship between late preeclampsia and echocardiographic variables in pregnant women showed a significant relationship between diastolic disorder (15% in the case group vs. 5% in the control group) (p = .035), systolic artery pressure (p = .002), and TR gradient (p = .003) with late preeclampsia; However, this relationship was not observed with other echocardiographic variables (p > .05). CONCLUSION: Since the role of transthoracic echocardiography in the management of women with preeclampsia has been emphasized by international groups, the results of this study suggest that increased TR Gradient and diastolic dysfunction are the most important echocardiography findings in patients with late preeclampsia.

Epidemic size, trend and spatiotemporal mapping of SARS-CoV-2 using geographical information system in Alborz Province, Iran.

BACKGROUND: The first confirmed cases of COVID-19 in Iran were reported in Qom city. Subsequently, the neighboring provinces and gradually all 31 provinces of Iran were involved. This study aimed to investigate the case fatility rate, basic reproductive number in different period of epidemic, projection of daily and cumulative incidence cases and also spatiotemporal mapping of SARS-CoV-2 in Alborz province, Iran. METHODS: A confirmed case of COVID-19 infection was defined as a case with a positive result of viral nucleic acid testing in respiratory specimens. Serial interval (SI) was fitted by gamma distribution and considered the likelihood-based R0 using a branching process with Poisson likelihood. Seven days average of cases, deaths, doubling times and CFRs used to draw smooth charts. kernel density tool in Arc GIS (Esri) software has been employed to compute hot spot area of the study site. RESULTS: The maximum-likelihood value of R0 was 2.88 (95%, CI: 2.57-3.23) in the early 14 days of epidemic. The case fatility rate for Alborz province (Iran) on March 10, was 8.33% (95%, CI:6.3-11), and by April 20, it had an increasing trend and reached 12.9% (95%,CI:11.5-14.4). The doubling time has been increasing from about two days and then reached about 97 days on April 20, 2020, which shows the slowdown in the spread rate of the disease. Also, from March 26 to April 2, 2020 the whole Geographical area of Karj city was almost affected by SARS-CoV-2. CONCLUSIONS: The R0 of COVID-19 in Alborz province was substantially high at the beginning of the epidemic, but with preventive measures and public education and GIS based monitoring of the cases,it has been reduced to 1.19 within two months. This reduction highpoints the attainment of preventive measures in place, however we must be ready for any second epidemic waves during the next months.

Molecular study of metallo-ß-lactamases and integrons in Acinetobacter baumannii isolates from burn patients.

BACKGROUND: Productions of metallo-ß-lactamases enzymes are the most common mechanism of antibiotic resistance to all beta-lactam classes (except monobactams) in Acinetobacter baumannii. MBLs are usually associated with gene cassettes of integrons and spread easily among bacteria. The current study was performed to detect the genes encoding MBLs and integron structures in A. baumannii isolates from burn patients. METHODS: This study was performed on 106 non-duplicate A. baumannii isolates from burn patients referred to Shahid Motahari Hospital in Tehran. Antibiotic susceptibility of A. baumannii isolates was performed using disk diffusion and broth microdilution method in accordance with the CLSI guidelines. The presence of class 1 integron and associated gene cassettes as well as MBLs-encoding genes including blaVIM, and blaIMP were investigated using PCR and sequencing techniques. RESULTS: In this cross-sectional study all (100%) of the A. baumannii isolates examined were multidrug resistant. All isolates were sensitive to colistin and simultaneously all were resistant to imipenem. PCR assays showed the presence of blaVIM and blaIMP genes in 102 (96.2%) and 62 (58.5%) isolates of A. baumannii respectively. In addition, 62 (58.5%) of the A. baumannii isolates carried integron class 1, of which 49 (79.0%) were identified with at least one gene cassette. Three types of integron class 1 gene cassettes were identified including: arr2, cmlA5, qacE1 (2300 bp); arr-2, ereC, aadA1, cmlA7, qacE1 (4800 bp); and aac(3)-Ic, cmlA5 (2250 bp). CONCLUSION: A high prevalence of MBLs genes, especially blaVIM, was identified in the studied MDR A. baumannii isolates. In addition, most of the strains carried class 1 integrons. Furthermore, the gene cassettes arrays of integrons including cmlA5 and cmlA7 were detected, for the first time, in A. baumannii strains in Iran.

A cross-sectional study on evaluation of complete blood count-associated parameters for the diagnosis of acute appendicitis.

BACKGROUND AND AIMS: Acute appendicitis is one of the common causes of abdominal surgeries, however, the rate of negative appendectomy is as high as 20% as the diagnosis of appendicitis is challenging. The study aimed to evaluate complete blood count (CBC)-associated parameters among positive and negative appendectomy patients and determine their diagnostic importance. METHODS: In this cross-sectional study, patients who suspected of acute appendicitis were included. Preoperative blood samples taken from these patients for a complete blood count. Following parameters evaluated from their CBC: white blood cell (WBC), platelet (PLT), mean platelet volume (MPV), neutrophils-to-lymphocytes ratio, platelets-to-lymphocytes ratio, red cell distribution width (RDW), and platelet distribution width (PDW). These parameters analyzed for the positive and negative appendectomy patients using statistical analysis. RESULTS: Of 200 patients included in the study, 30 patients (15%) underwent negative appendectomy. The mean neutrophils, WBC, red blood cells, neutrophils-to-lymphocytes, and platelets-to-lymphocytes ratio was significantly high among positive appendectomy patients, (P < .05), whereas MPV to platelet ratio was significantly less in this group. The highest diagnostic power for the diagnosis of appendicitis was of neutrophils-to-lymphocytes ratio with the sensitivity of 83.5% and the specificity of 90%. CONCLUSION: The findings of our study indicate that neutrophils-to-lymphocytes ratio alone is not sufficient for preoperative diagnosis of acute appendicitis and other CBC-related parameters did not have good sensitivity and specificity. Further studies are therefore required in this area.

Methylation of TGM-3 Promoter and Its Association with Oral Squamous Cell Carcinoma (OSCC).

BACKGROUND: Oral Squamous Cell Carcinoma (OSCC) is among the ten most common cancers worldwide. Hypermethylation of CpG sites in the promoter region and subsequent down-regulation of a tumor suppressor gene, TGM-3 has been proposed to be linked to different types of human cancers including OSCC. In this study, methylation status of CpG sites in the promoter region of TGM-3 has been evaluated in a cohort of patients with OSCC compared to normal controls. METHODS: Forty fresh tissue samples were obtained from newly diagnosed OSCC patients and normal individuals referred to dentistry clinic for tooth extraction. DNA was extracted, bisulfite conversion was performed and it was subjected to PCR using bisulfite-sequencing PCR (BSP) primers. Prepared samples were sequenced on a DNA analyzer with both forward and reverse primers of the region of interest. The peak height values of cytosine and thymine were calculated and methylation levels for each CpG site within the DNA sequence was quantified. RESULTS: Quantitative DNA methylation analyses in CpG islands revealed that it was significantly higher in OSCC patients compared to controls. DNA methylation at CpG1/CpG3/CpG5 (p=0.004-0.01) and CpG1/CpG3 (p=0.001-0.019) sites was associated with tumor stage and grade, respectively. Male OSCC patients had higher methylation rate at CpG3 (p=0.032), while smoker patients showed higher methylation rate at CpG6 (p=0.045). CONCLUSION: These results manifested the contribution of DNA methylation of TGM-3 in OSCC and its potential association with clinico-pathologic parameters in OSCC.

Educational needs on safe motherhood from the perspective of suburban women: A qualitative study.

BACKGROUND: Maternal mortality resulting from pregnancy and delivery complications is a sensitive indicator of women's status in the society, access to care services, and sufficiency and quality of healthcare and is the major indicator of a country's developmental status. The present study aimed at determination of educational needs regarding safe motherhood from suburban women's perspective. METHOD: This qualitative study with conventional content analysis approach was conducted in suburban healthcare centers of Alborz University of medical sciences from 23 October to 22 December 2019. The participants included 15 eligible Iranian suburban women who were selected through purposive sampling. The data were collected via in-depth semi-structured interviews and focus groups. Data were analyzes with MAXQDA10 software. RESULTS: Three main themes emerged from the analysis of the data (barriers against safe pregnancy, accountability multidimensional training, and threats and opportunities of distance learning), six categories, 11 subcategories and 547 codes. DISCUSSION: The results indicated that suburban women were less probable to be present in healthcare centers and receive the required information compared to their peers due to their conditions; provision of accessible training services appropriated to their conditions can greatly contribute to elimination of these problems.

Effect of Ammonium Chloride in addition to standard of care in outpatients and hospitalized COVID-19 patients: A randomized clinical trial.

OBJECTIVE: The COVID-19 pandemic has called an urgent need for drug repurposing to improve the outcome of the disease. Quaternary ammonium compounds have been demonstrated to have antiviral effects and may be of use against SARS-CoV-2 infections. DESIGN: In this double-blind, single-center study, we enrolled patients with positive PCR test and/or CT findings for COVID-19. The participants of each group were randomly assigned to Diphenhydramine Compound (Diphenhydramine + Ammonium Chloride) plus standard of care or to Diphenhydramine alone and standard of care groups. The primary outcome was all-cause mortality within 30 days of randomization. Secondary outcomes include viral burden, clinical status, assessed by a 5-point ordinal scale, and length of stay in hospitalized patients. RESULTS: A total of 120 patients were included in the trial, 60 of which were assigned to the Ammonium Chloride group. The primary endpoint was not statistically different between the two groups (HR: 3.02 (95% CI, 0.57-16.06; p = 0.195)). Recovery time and viral burden were significantly lower in the Ammonium Chloride group, corresponding to an odds ratios of 1.8 (95% CI, 1.15-2.83; p = 0.01) and 7.90 (95% CI, 1.62-14.17; p = 0.014), respectively. CONCLUSION: The findings of this study advocate the careful addition of Ammonium Chloride to standard of care for COVID-19 patients.

Effect of counselling on maternal-fetal attachment in unwanted pregnancy: a randomised controlled trial.

Purpose: The present study aimed to determine the effect of group counselling on Maternal-Fetal Attachment (MFA) in mothers with unwanted pregnancy.Methods: This study was a randomised clinical trial. The participants were 80 mothers with unwanted pregnancy during 28-34 weeks of pregnancy who referred to health centres of Karaj to receive prenatal care in 2018. The women were randomly assigned into intervention (N = 40) and control groups (N = 40). The intervention group received four weekly group counselling sessions to promote MFA and the control group received routine care. Cranley's Maternal-Fetal Attachment Scale was used to assess the attachment of mother to fetus at baseline and two weeks after counselling. An ANCOVA test was performed to evaluate the effect of intervention and the number of parity.Results: There was no significant difference between the two groups in terms of general health scores and attachment of mother to fetus at baseline, but after the intervention, the mean scores of MFA in the intervention group had a significant difference with the control group (p < 0.001); the ANCOVA test indicated that attachment scores were significant in terms of intervention and pregnancy group and attachment scores indicated further increase in the primipara group compared to the multipara group (p = 0.041).Conclusion: Considering the effectiveness of group counselling in improving MFA in unplanned pregnancy, it can be used in prenatal care.

Prediction of Stress Urinary Incontinence Using the Retrovesical (ß) Angle in Transperineal Ultrasound.

OBJECTIVES: The accurate, rapid diagnosis of stress urinary incontinence (SUI) in women can profoundly improve their sexual and psychosocial life. In this study, the diagnostic power of SUI was assessed by transperineal ultrasound. METHODS: In this hospital-based case-control study, married women who were referred to the gynecologic and ultrasound wards with negative urinalysis and culture results were enrolled by random sampling. Patients with positive cough signs based on the urodynamic testing data were considered cases, whereas control women showed no cough symptoms and were recruited from the same ward. RESULTS: There was a significant difference (P < .001) in bladder neck descent (mean ± SD, 10.89 ± 5.51 versus 7.08 ± 2.60 mm, respectively; P = .0001) and the retrovesical (ß) angle with the Valsalva maneuver (144.22° ± 19.63° versus 111.81° ± 24.47°; P < .001) between the case and control groups. Also, the ß angle without the Valsalva maneuver was higher in the case group (112.35° ± 23.10°) than the control group (120.17° ± 25.16°; P = .001). There was no case of a urinary leak, urethral diverticulitis, a bladder stone or mass, and cystourethrocele in the patients of each group. The results of multivariate logistic regression with a backward method showed that bladder neck descent (odds ratio [OR], 1.24; 95% confidence interval [CI], 1.09-1.40), the ß angles with and without the Valsalva maneuver (OR, 1.1; 95% CI, 1.06-1.13; and OR, 1.04; 95% CI, 1.01-1.06) were the predictors of SUI. A ß angle higher than 127° with the Valsalva maneuver, with an area under the curve of 0.89 (95% CI, 0.75-0.96), could very well predict the SUI response. This finding shows that it can be very well used to distinguish between normal and non-normal responses, with 89% sensitivity and 79% specificity. CONCLUSIONS: The ß angle with the Valsalva maneuver could very well predict the SUI response.
