Phylogenetic analysis, biofilm formation, antimicrobial resistance and relationship between these characteristics in Uropathogenic Escherichia coli.

BACKGROUND: In the present study, we examine the prevalence of phylogenetic groups, O-serogroups, adhesin genes, antimicrobial resistance, the level of gene expression associated with biofilm formation, and the presence of extended-spectrum beta-lactamase (ESBL) in UPEC strains isolated from both pediatric and adult patients. METHODS: In this cross-sectional study, 156 UPEC isolates were collected from UTI patients. ESBL-producing isolates were detected using the double-disc synergy (DDS) method, and biofilm formation was assessed through a microplate assay. The presence of O-serogroups, adhesion factors and resistance genes, including ESBLs and PMQR genes, was detected by PCR, and isolates were categorized into phylogenetic groups using multiplex PCR. Additionally, the quantitative real-time PCR method was also used to determine the expression level of genes related to biofilm. RESULTS: During the study period, 50.6% (79/156) of the samples were obtained from children, and 49.4% (77/156) were from adults. The highest rate of resistance was to NA (91.7%), while FM (10.9%) had the lowest rate of antibiotic resistance. In addition, 67.9% (106/156) of UPEC isolates were ESBL producers. Most of UPEC isolates belonged to phylogenetic group B2 (37.1%). This study revealed that blaCTX-M and qnrS are widely distributed among UPEC isolates. The mean expression levels of fimA genes were significantly higher in non-biofilm producers than in biofilm producers (p < 0.01). CONCLUSIONS: The high antibiotic resistance rates in this study highlight the significance of local resistance monitoring and investigating underlying mechanisms. Our findings indicate the dominance of phylogroup B2 and group D as the prevailing phylogenetic groups. Consequently, it is imperative to investigate the epidemiological aspects and characterize UPEC isolates across diverse regions and time frames.

Prevalence of cognitive frailty and its associated factors in a population of Iranian older adults.

BACKGROUND: In recent years cognitive frailty has emerged as an important predictor of adverse health outcomes in older adults. Herein, we aimed to investigate the prevalence and associated factors of cognitive frailty in a population of community-dwelling older adults in Iran. METHOD: This cross-sectional study was conducted as part of the second cycle of the Amirkola Health and Aging Project (AHAP). Physical frailty and cognitive impairment were evaluated using the FRAIL questionnaire and the mini-mental state examination (MMSE) respectively. Cognitive frailty was defined as co-existence of frailty and cognitive impairment without presence of dementia. Depression and disability were assessed using the Persian version of geriatric depression scale (GDS) and instrumental activities of daily living (IADL) questionnaire. RESULTS: Overall 1775 individuals (47.1% female) with mean age of 69.7 ± 7.3 years were included in the final analysis. The prevalence of cognitive frailty was 12.0%. The prevalence of cognitive frailty among males and females was 4.3% and 20.7%, respectively. After adjusting for all possible confounders through binary logistic regression analysis, factors such as older age (OR 1.06, CI 1.03-1.09), female gender (OR 2.25, CI 1.42-3.57), illiteracy (OR 3.84, CI 2.03-8.29), more comorbidities (OR 1.21, CI 1.12-1.31), depression (OR 2.01, CI 1.40-2.86), and greater IADL disability (OR 1.68, CI 1.44-3.96), were independently and significantly associated with cognitive frailty. CONCLUSION: In this population of Iranian older adults, prevalence of cognitive frailty was consistent with its estimated mean global prevalence. Age, gender, illiteracy, comorbidities, depression and IADL disability were associated with cognitive frailty. Further research is required to develop screening tools and prevention strategies.

Challenging the angiosome concept: Delineating peripheral arterial disease patterns in diabetic foot ulcers.

OBJECTIVES: The angiosome concept has significantly impacted diabetic foot ulcer management by highlighting the vascular anatomy's role in wound healing. However, its clinical applicability and validity remain debated due to complexities in foot blood supply and ulcer location determination. METHODS: A cross-sectional study was conducted on 84 individuals with diabetic foot ulcers undergoing lower limb angiography. Demographics, ulcer characteristics, and angiographic data were collected and analyzed using descriptive statistics and relevant tests. RESULTS: Digital subtraction angiography assessed 89 limbs with diabetic foot ulcers; males comprised 54.8%, primarily type 2 diabetes (96.4%), averaging 64.36 ± 10.09 years. Of 129 angiosomes, angiosome 2 (40.3%) had the highest ulcer incidence. Posterior tibial artery (PTA) involvement was predominant (72.9%), while external iliac artery (EIA) and profunda femoris artery (PFA) were least affected (2.4% each). Posterior tibial artery showed 46.5% complete occlusion. Angiosome 2 correlated notably with anterior tibial artery (ATA), peroneal artery (CPA), and PTA, but categorizing angiosomes by supply patterns showed no significant artery correlation (p > .05). CONCLUSIONS: The research indicates inconsistent support for below-the-knee artery involvement correlating with foot ulcer locations in angiosomes. While aiding vascular comprehension, the angiosome concept may not fully elucidate lower limb vascular complexities and ulcer genesis. Factors like collateral circulation should be noticed to understanding ulcer localization and severity, extending beyond angiosomal arterial supply.

Relationship Between Visceral Adipose Tissue and Bone Mineral Density in Older People: Results from AHAP Study.

INTRODUCTION: Due to discrepancy of the relationship between visceral adipose tissue (VAT) and bone mineral density (BMD), this study was performed to determine the relationship between BMD and VAT in the elderly. METHODOLOGY: This cross-sectional study is part of the second wave of Amirkola Health and Ageing Project (AHAP), including 1,200 people aged 60 years and older. BMD and VAT were measured by dual-energy X-ray absorptiometry (DXA) in Hologic equipment. Based on the amount of VAT, individuals were divided into four quartiles. Then, the data were statistically analyzed by SPSS22 software using chi-square, ANOVA, Pearson correlation coefficient and logistic regression. RESULTS: The mean age of the participants was 69.6 ± 6.9 year and the mean VAT was 862.6 ± 337.8 gram. In this study, people with osteoporosis had less VAT (p<0.0001). Furthermore, with the increase in the amount of VAT, BMD increased in the femoral region and lumbar spine (p<0.0001). There was a positive and significant correlation between VAT and BMD in the femoral region (r = 0.267) and lumbar spine (r = 0.197) (p<0.0001). After performing multiple logistic regression analysis in the presence of factors such as age, gender, body mass index and especially lean mass, the protective role of VAT against osteoporosis was maintained (OR=0.510, CI95% (0.290-0.895)) (P = 0.019). CONCLUSIONS: This study has shown that VAT can independently have a positive association with BMD in the elderly.

Predictors of quality of life and mental health in breast cancer survivors in Northern Iran.

BACKGROUND AND PURPOSE: The global incidence of breast cancer is the highest among all cancers and is the primary reason for cancer-related fatalities. Our study aimed to assess the predictors of quality of life (QOL) and mental health in breast cancer survivors in Northern Iran. METHODS: This cross-sectional study was done on 96 female breast cancer survivors between the ages of 20 and 65 and was based on convenience samples. We gathered information through demographic and fertility data, a QOL survey, and the Hospital Anxiety and Depression Scale (HADS). A significance level of P < 0.05 was set for the analysis. RESULTS: In this study, results showed that 11.5% of women had the optimal quality of life, 31.3% favorable quality of life, and 57.3% undesirable quality of life. The average HADS score was 20.14 ± 3.07, with anxiety scores of 10.21 ± 2.31 and depression scores of 9.93 ± 1.64. On multiple linear regression, marital relationship and the number of children were predictors of quality of life (ß=-17.624, p = 0.023 and ß=-7.427, p = 0.016, respectively), as well as the husband's education and having no history of other cancers in the woman, were the most important predictors of HADS (ß = 0.763, p = 0.039 and ß=-0.528, p = 0.016, respectively). CONCLUSION: It is crucial to provide exceptional care to breast cancer patients during treatment and post-recovery. Emotional and psychological support is a fundamental requirement for their well-being.

The impact of social support, physical and psychological performance on sleep outcomes in Iranian older adults: a case-control study.

BACKGROUND: Sleep quality is one of the most important factors to improve the quality of life in older adults and physical and mental health plays an essential role in better sleep quality. This study aimed to determine the impact of social support, and physical and psychological performance on sleep outcomes in Iranian older adults. METHODS: In this case-control study, 400 elder people, who were exposed to sleep problems, and 400 people without sleep problems were randomly selected during 2016-2017 in Amirkola, Iran. Subjects in the case and control groups were matched in terms of gender and age. The demographic characteristics, Duke Social Support Questionnaire (DSSI), Physical Activity Scale for the Elderly (PASE), Activity of Daily Living (ADL), Instrumental Activity of Daily Living (IADL), Mini-Mental State Examination (MMSE), and Pittsburgh Sleep Quality Questionnaire (PSQI) questionnaires were used to collect data. T-test, Chi-square, Pearson Correlation coefficient, and multiple Logistic regression were used for data analysis. RESULTS: The mean score of DSSI and its domains including social interaction (DSSI.Int) and social satisfaction (DSSI.Sat) were 28.15 ± 3.55, 9.31 ± 1.23, and 18.84 ± 2.88 in the case group and 28.87 ± 3.20, 9.48 ± 1.10, and 19.83 ± 2.44 in the control group, respectively. In this study, the mean scores of MMSE, PASE, ADL, and IADL were 25.36 ± 3.95, 101.71 ± 56.99, 13/97 ± 0.37, 20.59 ± 2/79; respectively. There was a significant inverse correlation between poor sleep quality with DSSI score (rho = -0.165, P < 0.0001), DSSI.Int (rho = -0.113, P < 0.001), DSSI.Sat (rho = -0.160, P < 0.0001), PASE (rho=-0.160, P < 0.0001), and IADL (rho = -0.112, P < 0.001) score. Therefore, more social support and physical activity improved the quality of sleep. There was a significant negative relationship between DSSI, and its domains with sleep quality in terms of gender. DSSI (rho = 0.25, P < 0.0001), DSSI.Int (P < 0.0001, rho=-0.18), and DSSI.Sat (P < 0.0001, rho=-0.22) was significant in men but not in women. The results of the adjusted logistic regression revealed a significant association between sleep quality problems and DSSI (p < 0.045, OR = 1.40), the use of hypnotic drugs (p < 0.0001, OR = 7.56), and occupation (p <0.03, OR= 12.66). CONCLUSIONS: The results of the present study suggest that low social support and all its domains, PASE, IADL, and using hypnotic drugs may play a role in the development of sleep problems. It can be used as an effective, safe, and low-cost strategy for promoting sleep quality in older adults.

Association of age-related eye diseases with cognitive frailty in older adults: a population-based study.

BACKGROUND: Age-related eye diseases and cognitive frailty (CF) are both important predictors of adverse health outcomes in older adults, however, little is known about their association. AIMS: To demonstrate the association between age-related eye diseases and cognitive frailty in a population of Iranian older adults. METHODS: In this cross-sectional, population-based study, we included 1136 individuals (female n = 514) aged 60 years and older (mean 68.8 ± 6.7 years) who participated in the second cycle of the Amirkola Health and Aging Project (AHAP) between 2016 and 2017. Cognitive function and frailty were evaluated based on Mini-Mental State Examination (MMSE) and the FRAIL scale respectively. Cognitive frailty was defined as coexistence of cognitive impairment (CI) and physical frailty (PF), excluding confirmed cases of dementia such as Alzheimer's disease. Cataract, diabetic retinopathy (DR), age-related macular degeneration (AMD), elevated intraocular pressure (IOP ≥ 21 mmHg) and glaucoma suspects (vertical cup to disc ratio (VCDR) ≥ 0.6) were diagnosed based on standardized grading protocols. Associations between eye diseases and cognitive frailty were evaluated through binary logistic regression analysis. RESULTS: Overall, CI, PF and CF were observed in 257 (22.6%), 319 (28.1%) and 114 (10.0%) participants respectively. After adjusting for confounders and ophthalmic conditions, individuals with cataract were more likely to have CF (OR 1.66; p-value 0.043), while DR, AMD, elevated IOP and glaucoma suspects (OR 1.32, 1.62, 1.42, 1.36, respectively) were not significantly associated with CF. Furthermore, cataract was significantly associated with CI (OR 1.50; p-value 0.022), but not with frailty (OR 1.18; p-value 0.313). CONCLUSION: Older adults with cataract were more likely to have cognitive frailty and cognitive impairment. This association demonstrates the implications of age-related eye diseases beyond ophthalmology and substantiates the need for further research involving cognitive frailty in the context of eye diseases and visual impairment.

Association between Toxoplasma gondii Infection and Nephrotic Syndrome Risk in Children: A Case-Control Study and Systematic Review.

Some evidence suggests toxoplasmosis as an etiology of nephrotic syndrome (NS) in children; however, no observational study evaluated this relationship. In a case-control study, we enrolled 35 children with NS and 37 healthy children. All participants were examined for anti-Toxoplasma immunoglobulin G and M (IgG and IgM) antibodies using enzyme-linked immunosorbent assay. We also systematically reviewed the literature to assess this relationship. Prevalence of anti-Toxoplasma IgG was 17.4% and 13.5% in cases and controls, respectively, indicating a non-significant association (adjusted odds ratio, 1.22, 95% confidence interval, 0.35-4.41). No subjects were seropositive for IgM. In a systematic review, we found that acute toxoplasmosis can induce NS in some children and anti-Toxoplasma treatment is effective in the remission of NS in these cases. In pediatrics with NS, acute toxoplasmosis should be considered as a neglected causative factor.

Global, Regional, and National Burden of Calcific Aortic Valve and Degenerative Mitral Valve Diseases, 1990-2017.

BACKGROUND: Nonrheumatic valvular diseases are common; however, no studies have estimated their global or national burden. As part of the Global Burden of Disease Study 2017, mortality, prevalence, and disability-adjusted life-years (DALYs) for calcific aortic valve disease (CAVD), degenerative mitral valve disease, and other nonrheumatic valvular diseases were estimated for 195 countries and territories from 1990 to 2017. METHODS: Vital registration data, epidemiologic survey data, and administrative hospital data were used to estimate disease burden using the Global Burden of Disease Study modeling framework, which ensures comparability across locations. Geospatial statistical methods were used to estimate disease for all countries, because data on nonrheumatic valvular diseases are extremely limited for some regions of the world, such as Sub-Saharan Africa and South Asia. Results accounted for estimated level of disease severity as well as the estimated availability of valve repair or replacement procedures. DALYs and other measures of health-related burden were generated for both sexes and each 5-year age group, location, and year from 1990 to 2017. RESULTS: Globally, CAVD and degenerative mitral valve disease caused 102 700 (95% uncertainty interval [UI], 82 700-107 900) and 35 700 (95% UI, 30 500-42 500) deaths, and 12.6 million (95% UI, 11.4 million-13.8 million) and 18.1 million (95% UI, 17.6 million-18.6 million) prevalent cases existed in 2017, respectively. A total of 2.5 million (95% UI, 2.3 million-2.8 million) DALYs were estimated as caused by nonrheumatic valvular diseases globally, representing 0.10% (95% UI, 0.09%-0.11%) of total lost health from all diseases in 2017. The number of DALYs increased for CAVD and degenerative mitral valve disease between 1990 and 2017 by 101% (95% UI, 79%-117%) and 35% (95% UI, 23%-47%), respectively. There is significant geographic variation in the prevalence, mortality rate, and overall burden of these diseases, with highest age-standardized DALY rates of CAVD estimated for high-income countries. CONCLUSIONS: These global and national estimates demonstrate that CAVD and degenerative mitral valve disease are important causes of disease burden among older adults. Efforts to clarify modifiable risk factors and improve access to valve interventions are necessary if progress is to be made toward reducing, and eventually eliminating, the burden of these highly treatable diseases.

Comparison of Bone Formation After Sinus Membrane Lifting Without Graft or Using Bone Substitute "Histologic and Radiographic Evaluation".

PURPOSE: Sinus floor elevation without using autogenous bone graft or bone substitute will eliminate donor site morbidity and reduce the cost and the risk of infection. We evaluated the bone gain after sinus membrane elevation without graft or using bone substitute in the same maxilla. Dental implants were inserted simultaneously as a 1-stage procedure. PATIENTS AND METHODS: In a split-mouth design, we conducted a randomized double-blinded clinical trial performing sinus lifts and simultaneous implant insertion in 10 healthy patients (n = 20). On the 1 site, we performed graft-less sinus lift (group 1) and on the other site Cerabone was used as bone substitute (group 2), respectively. The quantity and quality of bone gained in each sinus were evaluated and compared radiologically and histomorphometrically. RESULTS: After 6 months, the average gain of bone height was 6.21 and 9.58 mm in group 1 and 2, respectively, as measured radiologically (P < .001, P < .001). Histomorphometric examination showed significantly higher thickness of trabeculae and bone formation in group 1 (P = .003 and P = .002). However, the neovascularization was higher, but not significantly (P = .288). CONCLUSIONS: Radiological bone gain was similar in both groups. However, histomorphometric examination showed superior bone formation in graft-less group as compared to the Cerabone group. The blood clot seems to be an adequate filler and excellent medium for bone formation. More studies in split-mouth design are needed to compare different bone substitutes.

Global trends of hand and wrist trauma: a systematic analysis of fracture and digit amputation using the Global Burden of Disease 2017 Study.

BACKGROUND: As global rates of mortality decrease, rates of non-fatal injury have increased, particularly in low Socio-demographic Index (SDI) nations. We hypothesised this global pattern of non-fatal injury would be demonstrated in regard to bony hand and wrist trauma over the 27-year study period. METHODS: The Global Burden of Diseases, Injuries, and Risk Factors Study 2017 was used to estimate prevalence, age-standardised incidence and years lived with disability for hand trauma in 195 countries from 1990 to 2017. Individual injuries included hand and wrist fractures, thumb amputations and non-thumb digit amputations. RESULTS: The global incidence of hand trauma has only modestly decreased since 1990. In 2017, the age-standardised incidence of hand and wrist fractures was 179 per 100 000 (95% uncertainty interval (UI) 146 to 217), whereas the less common injuries of thumb and non-thumb digit amputation were 24 (95% UI 17 to 34) and 56 (95% UI 43 to 74) per 100 000, respectively. Rates of injury vary greatly by region, and improvements have not been equally distributed. The highest burden of hand trauma is currently reported in high SDI countries. However, low-middle and middle SDI countries have increasing rates of hand trauma by as much at 25%. CONCLUSIONS: Certain regions are noted to have high rates of hand trauma over the study period. Low-middle and middle SDI countries, however, have demonstrated increasing rates of fracture and amputation over the last 27 years. This trend is concerning as access to quality and subspecialised surgical hand care is often limiting in these resource-limited regions.

The burden of unintentional drowning: global, regional and national estimates of mortality from the Global Burden of Disease 2017 Study.

BACKGROUND: Drowning is a leading cause of injury-related mortality globally. Unintentional drowning (International Classification of Diseases (ICD) 10 codes W65-74 and ICD9 E910) is one of the 30 mutually exclusive and collectively exhaustive causes of injury-related mortality in the Global Burden of Disease (GBD) study. This study's objective is to describe unintentional drowning using GBD estimates from 1990 to 2017. METHODS: Unintentional drowning from GBD 2017 was estimated for cause-specific mortality and years of life lost (YLLs), age, sex, country, region, Socio-demographic Index (SDI) quintile, and trends from 1990 to 2017. GBD 2017 used standard GBD methods for estimating mortality from drowning. RESULTS: Globally, unintentional drowning mortality decreased by 44.5% between 1990 and 2017, from 531 956 (uncertainty interval (UI): 484 107 to 572 854) to 295 210 (284 493 to 306 187) deaths. Global age-standardised mortality rates decreased 57.4%, from 9.3 (8.5 to 10.0) in 1990 to 4.0 (3.8 to 4.1) per 100 000 per annum in 2017. Unintentional drowning-associated mortality was generally higher in children, males and in low-SDI to middle-SDI countries. China, India, Pakistan and Bangladesh accounted for 51.2% of all drowning deaths in 2017. Oceania was the region with the highest rate of age-standardised YLLs in 2017, with 45 434 (40 850 to 50 539) YLLs per 100 000 across both sexes. CONCLUSIONS: There has been a decline in global drowning rates. This study shows that the decline was not consistent across countries. The results reinforce the need for continued and improved policy, prevention and research efforts, with a focus on low- and middle-income countries.

Epidemiology of facial fractures: incidence, prevalence and years lived with disability estimates from the Global Burden of Disease 2017 study.

BACKGROUND: The Global Burden of Disease Study (GBD) has historically produced estimates of causes of injury such as falls but not the resulting types of injuries that occur. The objective of this study was to estimate the global incidence, prevalence and years lived with disability (YLDs) due to facial fractures and to estimate the leading injurious causes of facial fracture. METHODS: We obtained results from GBD 2017. First, the study estimated the incidence from each injury cause (eg, falls), and then the proportion of each cause that would result in facial fracture being the most disabling injury. Incidence, prevalence and YLDs of facial fractures are then calculated across causes. RESULTS: Globally, in 2017, there were 7 538 663 (95% uncertainty interval 6 116 489 to 9 493 113) new cases, 1 819 732 (1 609 419 to 2 091 618) prevalent cases, and 117 402 (73 266 to 169 689) YLDs due to facial fractures. In terms of age-standardised incidence, prevalence and YLDs, the global rates were 98 (80 to 123) per 100 000, 23 (20 to 27) per 100 000, and 2 (1 to 2) per 100 000, respectively. Facial fractures were most concentrated in Central Europe. Falls were the predominant cause in most regions. CONCLUSIONS: Facial fractures are predominantly caused by falls and occur worldwide. Healthcare systems and public health agencies should investigate methods of all injury prevention. It is important for healthcare systems in every part of the world to ensure access to treatment resources.

Burden of injury along the development spectrum: associations between the Socio-demographic Index and disability-adjusted life year estimates from the Global Burden of Disease Study 2017.

BACKGROUND: The epidemiological transition of non-communicable diseases replacing infectious diseases as the main contributors to disease burden has been well documented in global health literature. Less focus, however, has been given to the relationship between sociodemographic changes and injury. The aim of this study was to examine the association between disability-adjusted life years (DALYs) from injury for 195 countries and territories at different levels along the development spectrum between 1990 and 2017 based on the Global Burden of Disease (GBD) 2017 estimates. METHODS: Injury mortality was estimated using the GBD mortality database, corrections for garbage coding and CODEm-the cause of death ensemble modelling tool. Morbidity estimation was based on surveys and inpatient and outpatient data sets for 30 cause-of-injury with 47 nature-of-injury categories each. The Socio-demographic Index (SDI) is a composite indicator that includes lagged income per capita, average educational attainment over age 15 years and total fertility rate. RESULTS: For many causes of injury, age-standardised DALY rates declined with increasing SDI, although road injury, interpersonal violence and self-harm did not follow this pattern. Particularly for self-harm opposing patterns were observed in regions with similar SDI levels. For road injuries, this effect was less pronounced. CONCLUSIONS: The overall global pattern is that of declining injury burden with increasing SDI. However, not all injuries follow this pattern, which suggests multiple underlying mechanisms influencing injury DALYs. There is a need for a detailed understanding of these patterns to help to inform national and global efforts to address injury-related health outcomes across the development spectrum.

Epidemiology of injuries from fire, heat and hot substances: global, regional and national morbidity and mortality estimates from the Global Burden of Disease 2017 study.

BACKGROUND: Past research has shown how fires, heat and hot substances are important causes of health loss globally. Detailed estimates of the morbidity and mortality from these injuries could help drive preventative measures and improved access to care. METHODS: We used the Global Burden of Disease 2017 framework to produce three main results. First, we produced results on incidence, prevalence, years lived with disability, deaths, years of life lost and disability-adjusted life years from 1990 to 2017 for 195 countries and territories. Second, we analysed these results to measure mortality-to-incidence ratios by location. Third, we reported the measures above in terms of the cause of fire, heat and hot substances and the types of bodily injuries that result. RESULTS: Globally, there were 8 991 468 (7 481 218 to 10 740 897) new fire, heat and hot substance injuries in 2017 with 120 632 (101 630 to 129 383) deaths. At the global level, the age-standardised mortality caused by fire, heat and hot substances significantly declined from 1990 to 2017, but regionally there was variability in age-standardised incidence with some regions experiencing an increase (eg, Southern Latin America) and others experiencing a significant decrease (eg, High-income North America). CONCLUSIONS: The incidence and mortality of injuries that result from fire, heat and hot substances affect every region of the world but are most concentrated in middle and lower income areas. More resources should be invested in measuring these injuries as well as in improving infrastructure, advancing safety measures and ensuring access to care.

Effectiveness of extracorporeal blood purification (hemoadsorption) in patients with severe coronavirus disease 2019 (COVID-19).

BACKGROUND: Extracorporeal blood purification has been proposed as one of the therapeutic approaches in patients with coronavirus infection, because of its beneficial impact on elimination of inflammatory cytokines. METHODS: This controlled trial has been conducted on critically ill COVID-19 patients admitted in the state hospital affiliated to Babol University of Medical Sciences, Iran who received different antiviral and antibacterial drugs, and different modalities of respiratory treatments and did not have positive clinical improvement. No randomization and blindness was considered. All of the participants underwent three sessions of resin-directed hemoperfusion using continuous renal replacement therapy with a mode of continuous venovenous hemofiltration (CVVH). RESULTS: Five men and five women with a mean age of 57.30 ± 18.07 years have been enrolled in the study; and six of them have improved after the intervention. Peripheral capillary oxygen saturation (SpO2) changed after each session. Mean SpO2 before the three sessions of hemoperfusion was 89.60% ± 3.94% and increased to 92.13% ± 3.28% after them (p < 0.001). Serum IL-6 showed a reduction from 139.70 ± 105.62 to 72.06 ± 65.87 pg/mL (p = 0.073); and c-reactive protein decreased from 136.25 ± 84.39 to 78.25 ± 38.67 mg/L (P = 0.016). CONCLUSIONS: Extracorporeal hemoadsorption could improve the general condition in most of recruited patients with severe coronavirus disease; however, large prospective multicenter trials in carefully selected patients are needed to definitely evaluate the efficacy of hemoperfusion in COVID-19 patients. TRIAL REGISTRATION: The research protocol has been registered in the website of Iranian Registry of Clinical Trials with the reference number IRCT20150704023055N2 .

Effect of Alpinia officinarum Hance rhizome extract on spermatogram factors in men with idiopathic infertility: A prospective double-blinded randomised clinical trial.

Despite scientific advances, many of the treatments in male infertility remained indeterminate. In recent years, the attention to herbal remedies as an effective treatment for male infertility is considerable. We designed this study to determine the effects of Alpinia officinarum on the results of semen analysis in men with idiopathic infertility. In this clinical trial, seventy-six participants with idiopathic infertility were included in the intervention (plant treatment: n = 31; placebo: n = 29). Participants were randomised to take capsules containing dried extract of A. officinarum rhizome or placebo on a daily (total daily dosage of 300 mg) basis for 3 months. After 12 weeks of intervention, the sperm count and total number of spermatozoa with normal morphology were increased in participants treated with A. officinarum extract compared with the placebo group. The mean sperm count was initially 52 × 106  ± 24 × 106 /ml which changed to 71 × 106  ± 23 × 106 /ml, after intervention (p = 0.043). Also, the mean percentage of spermatozoa with normal morphology was 14.34% ± 9.16% before the treatment which significantly increased to 19% ± 14.89% (p < 0.001). Alpinia officinarum, a traditional medicine remedy, can be effective in the improvement of sperm morphology and sperm count in idiopathic infertility without causing adverse effects.

Stoss therapy using fortified biscuit for vitamin D-deficient children: a novel treatment.

BACKGROUND: To evaluate the efficacy of stoss therapy using fortified biscuit for vitamin D-deficient children. METHODS: A total of 108 children aged 30-72 months with vitamin D deficiency were studied in a randomized single-blind clinical trial. The deficient children were assigned to three groups, namely, vitamin D-fortified biscuit (BG), capsule vitamin D (CG), and ampoule vitamin D (AG). Capsules and biscuits containing 50,000 IU of cholecalciferol were consumed twice per week for 3 consecutive weeks. Ampoules with 300,000 IU of cholecalciferol were injected intramuscularly in a single dose. Three weeks after treatment, serum 25(OH)D concentrations were measured, and the three groups were compared. RESULTS: Each method of treatment could increase the mean serum 25(OH)D concentration to optimal level. Serum 25(OH)D concentrations ≥100 ng/mL were observed in six children, including four from AG and two from CG (P = 0.09). The comparison of the mean serum 25(OH)D concentrations after treatment showed between ampoule and capsule (P = 0.3) and capsule and biscuit (P = 0.62) were insignificant; however, the ampoule and biscuit groups differed significantly (P = 0.012). CONCLUSION: Stoss therapy using fortified biscuit may be an effective way to improve compliance in children who cannot take capsules without adverse effects and may also be recommended for prevention purposes.

Comparison of the Effect of Dexamethasone and Tranexamic Acid, Separately or in Combination on Post-Rhinoplasty Edema and Ecchymosis.

BACKGROUND: Dexamethasone and tranexamic acid are used to decrease post-rhinoplasty periorbital edema and ecchymosis. We compared the impact of each medication separately or in combination in this regard. METHODS: A prospective, randomized triple-blinded study was undertaken on 60 patients who underwent primary open rhinoplasty. They were divided into four groups: Group D (n = 15) received 8 mg dexamethasone, group T (n = 15) received 10 mg/kg tranexamic acid, group DT (n = 15) received both 8 mg dexamethasone and 10 mg/kg tranexamic acid, and group P (n = 15) received neither medication and served as the placebo control group. The medications were given intravenously (IV) 1 h before and three doses every 8 h postoperatively. Digital photographs were taken on the first, third and seventh postoperative days. One expert examiner blinded to the study evaluated the periorbital edema and ecchymosis on a scale of 0-4. Periorbital edema and ecchymosis were examined in all groups. RESULTS: In group D, group T and group DT, periorbital edema and ecchymosis ratings were significantly lower compared with the control group (p < 0.01). No statistically significant difference was seen in preventing or decreasing both periorbital edema and ecchymosis among group D, group T and group DT. CONCLUSION: Tranexamic acid and dexamethasone, separately or in combination, had similar effects in reducing periorbital edema and ecchymosis in open rhinoplasty. Combined application did not show a significantly higher beneficial effect in this regard. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Citalopram and group psychotherapy in breast cancer patients: A randomized clinical trial.

Background: Depression is a common psychiatric disorder in breast cancer patients. This study was designed to evaluate the clinical efficacy of group psychotherapy on breast cancer patients with depressive disorder who took citalopram. Methods: This clinical trial was conducted on 40 breast cancer patients with depressive disorder. The control group received citalopram 20-40 mg/ day for 12 weeks and the intervention group participated in 8 sessions of group psychotherapy in addition to the same dose of citalopram. At the baseline and 3, 6, and 12 weeks after treatment, patients were followed- up. Treatment outcomes and quality of life were compared between the 2 groups. Results: Overall, the depression score of Hospital Anxiety and Depression Scale (HADS) at baseline with the mean of 11.6±1.6 was signed in the range of clinical depression and after intervention it declined to 8.8±3.6 (in the 3rd week), 7.1±3.9 (6th week), and 5.9±4.5 (12th week). Furthermore, HADS anxiety score at baseline with the mean of 12.6±2.6 was signed in the range of clinical anxiety and after intervention it declined to 9.1±3.0, 7.3±4.1, and 6.0±4.0, respectively. This improvement was significantly more in the combined therapy intervention group (p<0.001). The mean score of quality of life based on WHO QOL-BREF questionnaire increased by 1.85 fold in the case group, improved from 44.09 to 81.70, while the slight change was observed in the control group (p<0.001). During the treatment, no significant adverse drug event was observed in the 2 groups (p>0.05). Conclusion: Group psychotherapy has a significant effect on improving depression, anxiety, and quality of life in breast cancer patients.
