RESUMO

BACKGROUND: Sex reassignment surgery (SRS) is a necessary step in transitioning into the desired gender for male-to-female transgender individuals. This study focuses on a rare complication developed following SRS, aiming to highlight potential complications associated with this procedure. CASE PRESENTATION: This report describes a 49-year-old transgender woman with a history of SRS who developed bloody diarrhea and neovaginal bleeding 10 years later. A colonoscopy revealed features compatible with ulcerative colitis, which was confirmed by a biopsy. CONCLUSIONS: The unpredictable clinical course of this phenomenon may prompt surgeons to reconsider the use of a rectosigmoid colon to create a neovagina. This case report underscores the necessity of long-term monitoring for gastrointestinal complications in transgender women post-SRS when a rectosigmoid colon segment is utilized for neovaginal construction.

RESUMO

INTRODUCTION: The quality of care and patient satisfaction is closely linked with dignity, which is a crucial component of therapy and care. However, there is very little study on dignity in the context of mental health care. Planning for ongoing patient care might benefit from an understanding of the notion of dignity by exploring the experiences of patients, caregivers and companions of patients who have a history of hospitalization in mental health institutions. To retain patients' dignity while they were being treated in mental wards, this study sought to understand the experiences of patients, caregivers and companions of patients. MATERIALS AND METHODS: This investigation was qualitative. Semistructured interviews and focus groups were utilized to collect the data. The purposeful sampling method was employed for participant recruitment, which continued until data saturation. Two focus group discussions and 27 interviews were conducted. Participants included 8 patients, 2 patients' family members (companions), 3 psychologists, 4 nurses and 11 psychiatrists. Two focus group discussions were held with seven family members or companions of patients. Thematic analysis was used for data analysis. RESULTS: The primary theme that emerged was the infringement of patients' dignity, through negative guardianship, dehumanization and violations of their rights. Subthemes included dehumanization, worthlessness and namelessness, patient rights violations and stripping patients of authority. CONCLUSION: Our results suggest that, regardless of the severity of the illness, the nature of psychiatric illness significantly compromises patients' dignity. Mental health practitioners, due to their sense of guardianship, may unintentionally treat patients with mental health disorders, thus compromising the patient's dignity. PATIENT OR PUBLIC CONTRIBUTION: The research team's experiences as a psychiatrist, doctor and nurse informed the study's objectives. Nurses and psychiatrists who work in the healthcare industry designed and conducted the study. The primary authors, who are healthcare providers, collected and analysed the required data. Furthermore, the entire study team contributed to the writing of the manuscript. Study participants were involved in the data collection and analysis.

RESUMO

BACKGROUND: The combination of sofosbuvir and daclatasvir has shown preliminary efficacy for hospitalized patients with COVID-19 in four open-label studies with small sample sizes. This larger trial aimed to assess if the addition of sofosbuvir/daclatasvir to standard care improved clinical outcomes in hospitalized patients with COVID-19. METHODS: This was a placebo-controlled, double-blind, randomized clinical trial in adults hospitalized with COVID-19 at 19 hospitals in Iran. Patients were randomized to oral sofosbuvir/daclatasvir 400/60 mg once-daily or placebo in addition to standard of care. Patients were included if they had positive PCR or diagnostic chest CT, O2 saturation <95% and compatible symptoms. The primary outcome was hospital discharge within 10 days of randomization. Secondary outcomes included mortality and time to clinical events. The trial is registered on the Iran Registry of Clinical Trials under IRCT20200624047908N1. RESULTS: Between July and October 2020, 1083 patients were randomized to either the sofosbuvir/daclatasvir arm (n = 541) or the placebo arm (n = 542). No significant difference was observed in the primary outcome of hospital discharge within 10 days, which was achieved by 415/541 (77%) in the sofosbuvir/daclatasvir arm and 411/542 (76%) in the placebo arm [risk ratio (RR) 1.01, 95% CI 0.95-1.08, P = 0.734]. In-hospital mortality was 60/541 (11%) in the sofosbuvir/daclatasvir arm versus 55/542 (10%) in the placebo arm (RR 1.09, 95% CI 0.77-1.54, P = 0.615). No differences were observed in time to hospital discharge or time to in-hospital mortality. CONCLUSIONS: We observed no significant effect of sofosbuvir/daclatasvir versus placebo on hospital discharge or survival in hospitalized COVID-19 patients.

RESUMO

BACKGROUND: The combination of sofosbuvir and daclatasvir has a well-established safety profile and improves clinical outcomes in HCV patients. In silico and in vitro studies suggest that sofosbuvir/daclatasvir may show antiviral activity against SARS-CoV-2. METHODS: Three clinical trials comparing sofosbuvir/daclatasvir-based regimens with a comparator in hospitalized COVID-19 patients were combined in a meta-analysis. The primary outcomes measured were clinical recovery within 14 days of randomization, time to clinical recovery and all-cause mortality. A two-step approach was used to analyse individual-level patient data. The individual trial statistics were pooled using the random-effects inverse-variance model. RESULTS: Our search identified eight studies of which three met the inclusion criteria (n = 176 patients); two studies were randomized and one was non-randomized. Baseline characteristics were similar across treatment arms. Clinical recovery within 14 days of randomization was higher in the sofosbuvir/daclatasvir arms compared with control arms [risk ratio = 1.34 (95% CI = 1.05-1.71), P = 0.020]. Sofosbuvir/daclatasvir improves time to clinical recovery [HR = 2.04 (95% CI = 1.25-3.32), P = 0.004]. The pooled risk of all-cause mortality was significantly lower in the sofosbuvir/daclatasvir arms compared with control arms [risk ratio = 0.31 (95% CI = 0.12-0.78), P = 0.013]. CONCLUSIONS: Available evidence suggests that sofosbuvir/daclatasvir improves survival and clinical recovery in patients with moderate to severe COVID-19. However, the sample size for analysis was relatively small, one of the trials was not randomized and the designs were not standardized. These results need to be confirmed in larger randomized controlled trials.

RESUMO

Resistance-Nodulation-Division (RND) efflux pumps are responsible for multidrug resistance in Pseudomonas aeruginosa. The present study aimed to evaluate the overexpression of RND efflux pumps and its role in the antibiotic resistance of P. aeruginosa clinical isolates. A number of 122 isolates were obtained from three military hospitals in Tehran, Iran. In order to determine the antibiotic resistance, the isolates were identified and assessed by the disk diffusion and agar dilution methods. This study investigated the gene expression of four multi-drug efflux pump systems (MexAB-OprM, MexCD-OprJ, MexEF-OprN and MexXY (-OprA)) and its correlation with antibiotic resistance. The isolates indicated that the highest resistance rate was against ticarcillin (80%), followed by ciprofloxacin (74%) and meropenem (71%). Most of them expressed mexB (69%), mexC (28.7%), mexE (43.4%), and mexY (74.6%), suggesting that mexB and mexY were highly expressed in the studied strains. The overexpression of mexB and mexY was significantly more prevalent in the ICU wards (p = 0.033). Furthermore, there was a significant correlation between the expression of RND-type efflux pumps and the resistance to most anti-pseudomonal antibiotics.

RESUMO

This study aimed to investigate the validity and factor structure of the Self-Assessed Wisdom Scale (SAWS; Webster in J Adult Dev 10:13-22, 2003) in an Iranian population. Participants (235 male, 340 female) were recruited in Tehran, Iran and ranged in age from 17 to 88 years. Cronbach alpha's for the subscales ranged from .63 to .81, and their inter-correlations ranged from .42 to .53. Exploratory factor analysis extracted 5 factors that were similar with the original structure. Confirmatory factor analysis supported 5-factor model of the SAWS. The SAWS's total and subscale scores positively correlated with two other measures of wisdom (indicating convergent validity). The SAWS correlated weakly with age. Women scored higher in the SAWS subscales of emotional regulation, reminiscence/reflectiveness, and humor, which accounted for a significant gender difference in total wisdom. Although the age differences are consistent with prior research, the gender differences are relatively novel. Overall, results indicate that the SAWS has excellent psychometric properties and can be used in cross-cultural work.

RESUMO

BACKGROUND: Currently no effective antiviral therapy has been found to treat COVID-19. The aim of this trial was to assess if the addition of sofosbuvir and daclatasvir improved clinical outcomes in patients with moderate or severe COVID-19. METHODS: This was an open-label, multicentre, randomized controlled clinical trial in adults with moderate or severe COVID-19 admitted to four university hospitals in Iran. Patients were randomized into a treatment arm receiving sofosbuvir and daclatasvir plus standard care, or a control arm receiving standard care alone. The primary endpoint was clinical recovery within 14 days of treatment. The study is registered with IRCT.ir under registration number IRCT20200128046294N2. RESULTS: Between 26 March and 26 April 2020, 66 patients were recruited and allocated to either the treatment arm (n = 33) or the control arm (n = 33). Clinical recovery within 14 days was achieved by 29/33 (88%) in the treatment arm and 22/33 (67%) in the control arm (P = 0.076). The treatment arm had a significantly shorter median duration of hospitalization [6 days (IQR 4-8)] than the control group [8 days (IQR 5-13)]; P = 0.029. Cumulative incidence of hospital discharge was significantly higher in the treatment arm versus the control (Gray's P = 0.041). Three patients died in the treatment arm and five in the control arm. No serious adverse events were reported. CONCLUSIONS: The addition of sofosbuvir and daclatasvir to standard care significantly reduced the duration of hospital stay compared with standard care alone. Although fewer deaths were observed in the treatment arm, this was not statistically significant. Conducting larger scale trials seems prudent.

RESUMO

BACKGROUND: Meaning in life is one of the psychological domains that is most severely affected in patients with life-threatening illnesses. The importance of meaning-making mandates the development of reliable tools to assess this construct. Steger's Meaning in Life Questionnaire (MLQ) is one of the most valid and reliable instruments that determines the search for and presence of meaning in life. The present study was conducted to provide psychometric data on the MLQ in a sample of patients with life-threatening illnesses. METHODS: The MLQ was completed by 301 patients (aged 20-80 years) diagnosed with life-threatening illnesses (cancer and multiple sclerosis) and referred to hospitals. Confirmatory factor analysis and Pearson's correlation test were used to determine the construct validity of the questionnaire. RESULTS: The confirmatory factor analysis supported the original two-factor model of the MLQ, comprised of the presence of meaning (five items) and search for meaning (five items). The responses to the MLQ did not differ by sociodemographic factors. Most importantly, contrary to previous findings, the correlation between the two subscales, i.e., search for meaning and presence of meaning, was significant and positive. CONCLUSION: The results showed that the MLQ is a valid and reliable measure for assessing meaning in life that can be applied in research on meaning in life among other patient populations.

RESUMO

BACKGROUND: Acute pancreatitis is a serious complication of endoscopic retrograde cholangiopancreatography (ERCP). The aim of this noninferiority study was to evaluate the effectiveness of pancreatic duct (PD) stenting plus pharmacological prophylaxis vs. pharmacological prophylaxis alone in the prevention of post-ERCP pancreatitis (PEP) in high risk patients. METHODS: In this randomized, controlled, double-blind, noninferiority trial, patients at high risk of developing PEP were randomly allocated to pharmacological prophylaxis (rectal indomethacin, sublingual isosorbide dinitrate, and intravenous hydration with Ringer's lactate) plus PD stenting (group A) or pharmacological prophylaxis alone (group B). The rate and severity of PEP, serum amylase levels, and length of hospital stay after ERCP were assessed. RESULTS: During 21 months, a total of 414 patients (mean age 55.5 ±â€Š17.0 years; 60.2 % female) were enrolled (207 in each group). PEP occurred in 59 patients (14.3 %, 95 % confidence interval [CI] 11.1 % - 17.9 %: 26 patients [12.6 %, 95 %CI 8.6 % - 17.6 %] in group A and 33 [15.9 %, 95 %CI 11.4 % - 21.4 %] in group B). There was no significant difference between the two groups in PEP severity (P = 0.59), amylase levels after 2 hours (P = 0.31) or 24 hours (P = 0.08), and length of hospital stay (P = 0.07). CONCLUSIONS: The study failed to demonstrate noninferiority or inferiority of pharmacological prophylaxis alone compared with PD stenting plus pharmacological prophylaxis in the prevention of PEP in high risk patients.

RESUMO

BACKGROUND: Cognitive status is important for performing the assessment and treatment of dysphagia. Nonetheless, the cognitive neuropsychological profile of patients with stroke and dysphagia is not studied as deeply enough as it should be. On the one hand, focal and non-focal brain lesions may lead to dysphagia and cognitive disorders, and on the other hand, the cognitive status possibly affects swallowing. In this study, cognition is supposed to be a mediator between brain lesion and swallowing disorder (dysphagia). The role of cognition and attention as mediators between brain lesion and dysphagia was evaluated via three causal models in which the causal mechanisms of swallowing were explained. METHODS: Eighty-eight patients with their first stroke (34 women and 54 men) in the acute phase (mean: 3.5 days after stroke; SD: 2.7) participated in this research. The data of dysphagic and non-dysphagic patients were entered into structural equation models. Two relationships were estimated: a direct relationship between brain lesion and dysphagia and an indirect association between brain lesion and dysphagia through cognition and attention. RESULTS: The goodness-of-fit indices confirmed the three models. Our first model proved a good fit [CFI = 1.00; TLI = 1.00]. The second model revealed an appropriate goodness of fit [CFI = 1.00; TLI = 1.00]. Our third model also showed a good fit [CFI = 1.00; TLI = 1.00]. CONCLUSION: It is suggested that in the assessment and treatment of dysphagia, cognition is better to be considered as a mediator along with physical aspects of dysphagia.

RESUMO

BACKGROUND: Limited data available about the mechanisms of dysphagia and areas involving swallow after brain damage; accordingly it is hard to predict which cases are more likely to develop swallowing dysfunction based on the neuroimaging. The aim of this study was to investigate the relationship between brain lesions and dysphagia in a sample of acute conscious stroke patients. MATERIALS AND METHODS: In a cross-sectional study, 113 acute conscious stroke patients (69 male mean [standard deviation (SD)] age 64.37 [15.1]), participated in this study. Two neurologists and one radiologist localized brain lesions according to neuroimaging of the patients. Swallowing functions were assessed clinically by an expert speech pathologist with the Mann Assessment of Swallowing Ability (MASA). The association of brain region and swallowing problem was statistically evaluated using Chi-square test. RESULTS: Mean (SD) MASA score for the dysphagic patients was 139.61 (29.77). Swallowing problem was significantly more prevalent in the right primary sensory (P = 0.03), right insula (P = 0.005), and right internal capsule (P = 0.05). CONCLUSION: It may be concluded from these findings that the right hemisphere lesions associated with occurring dysphagia. Further studies using more advanced diagnostic tools on big samples particularly in a perspective structure are needed.

RESUMO

BACKGROUND: Any loss or deviation in body function and structure is considered impairment, whereas limitations on activities are fundamental to the definition of disability. Although it seems intuitive that the two should be closely related, this might not be the case; there is some evidence that psychosocial factors are more important determinants of disability than are objective impairments. However, the degree to which this is the case has been incompletely explored. QUESTIONS/PURPOSES: The purpose of this study was to determine if disability (as measured by the Disabilities of the Arm, Shoulder and Hand [DASH] and the Michigan Hand Questionnaire [MHQ]) and pain intensity correlate with impairment (as measured by the American Medical Association [AMA] impairment guide). Secondary study questions addressed the effect of pain intensity and symptom of depression on predicting disability. METHODS: Impairment and disability were evaluated in a sample of 107 hand-injured patients a mean of 11 months after injury. Impairment rating was performed prospectively. From the patients who came for therapy, they were invited to fill out the questionnaire and evaluated for impairment rating. Response variables of DASH, MHQ, and visual analog scale pain intensity values were collected at the same setting. Other explanatory variables included demographic, injury-related, and psychological factors (symptoms of depression measured with the Beck Depression Inventory). Initial bivariate and multivariate analyses were performed to determine correlations of disability and pain to impairment rating and other exploratory variables. RESULTS: Disability as measured by the DASH showed intermediate correlation with AMA impairment (r = 0 .38, beta = 0.36, p = 0.000). Together with gender, it accounted for only 22% of the variability in DASH scores. Similarly, MHQ score correlated with impairment rating (r = -0.24, beta = -0.23, p < 0.05). However, together with age, injured hand accounted for only 19% of the variability in MHQ scores. However, pain intensity did not correlate with impairment (r = -0.46, p > 0.05). Interestingly, pain intensity did correlate with the time passed from surgery but it was correlated with symptom of depression (r(2) = 0.10, beta = 0.33, p = 0.001). CONCLUSIONS: The limited correlation between impairment and disability emphasizes the importance of factors other than pathophysiology in human illness behavior. These may include physical (pain, dominant injured hand) and conditional factors (time since surgery) or psychological factors such as depression and adapting; all mentioned can be considered as personal factors that may be different in each patient. So considering personal difference and any other condition except the impairment alone can help to better plan interventions and also diminish disability level. LEVEL OF EVIDENCE: Level III, therapeutic study.

RESUMO

OBJECTIVES: Acute pancreatitis is the most common adverse event of endoscopic retrograde cholangiopancreatography (ERCP). Recent data suggest that indomethacin can reduce the risk of post-ERCP pancreatitis (PEP) in high-risk individuals. However, whether the combination of indomethacin and sublingual nitrates is superior to indomethacin alone is unknown. Therefore, we aimed to evaluate the efficacy of rectally administered indomethacin plus sublingual nitrate compared with indomethacin alone to prevent PEP. METHODS: During a 17-month period, all eligible patients who underwent ERCP were enrolled in this study. We excluded patients who had undergone a prior endoscopic sphincterotomy. In a double-blind controlled randomized trial, patients received a suppository containing 100 mg of indomethacin, plus 5 mg of sublingual nitrate (group A), or a suppository containing 100 mg of indomethacin, plus sublingual placebo (group B), before ERCP. Serum amylase levels and clinically pertinent evaluations were measured in all patients after ERCP. RESULTS: Of the 300 enrolled patients, 150 received indomethacin plus nitrate. Thirty-three patients developed pancreatitis: 10 (6.7%) in group A and 23 (15.3%) in group B (P=0.016, risk ratio=0.39, 95% confidence intervals (CI): 0.18-0.86). More than 80% of the patients were at high risk of developing pancreatitis after ERCP. Absolute risk reduction, relative risk reduction, and number needed to treat for the prevention of PEP were 8.6% (95% CI: 4.7-14.5), 56.2% (95% CI: 50.6-60.8), and 12 (95% CI: 7-22), respectively. CONCLUSIONS: Combination of rectal indomethacin and sublingual nitrate given before ERCP was significantly more likely to reduce the incidence of PEP than indomethacin suppository alone. Multicenter trials to confirm these promising findings are needed.

RESUMO

Central neuropathic pain (CNP) is a complicated medical problem that involves both the spinal and supraspinal regions of the central nervous system. Estrogen, a neuroprotective agent, has been considered a possible candidate for CNP treatment. In this study, we examined the effects of a single dose of 17ß-estradiol on glutamate levels in the ventral posterolateral (VPL) nucleus of the rat thalamus. Furthermore, we determined whether there was a correlation between glutamate levels and neuropathic pain induced by unilateral electrolytic spinothalamic tract (STT) lesion. STT lesioning was performed in male Wistar rats at the T8-T9 vertebrae; rats were then administered 17ß-estradiol (4 mg/kg, i.p.) 30 min after injury. Glutamate samples were collected using a microdialysis probe and quantified by high performance liquid chromatography. Mechanical allodynia (MA) and thermal hyperalgesia (TH) thresholds were measured pre-injury and 7, 14, and 28 days post-injury. We found that STT lesion significantly increased glutamate levels in the ipsilateral VPL nucleus 14 and 28 days post-injury; this was accompanied by allodynia and hyperalgesia in the hind paws of the rats. Administering 17ß-estradiol to the rats decreased glutamate levels in the ipsilateral VPL nucleus and significantly increased MA and TH thresholds. These results suggest that glutamate in the VPL nucleus of the thalamus is involved in the pathology of neuropathic pain after STT injury; furthermore, 17ß-estradiol may attenuate this neuropathic pain by decreasing glutamate levels.

RESUMO

BACKGROUND: This study assessed the prevalence of gastroesophageal reflux disease (GERD) in a general adult population in Iran. The association between GERD and various factors was also evaluated. METHODS: We performed a cross-sectional study on 163,018 individuals aged over 35 who were enrolled in the PERSIAN cohort. GERD was defined as the occurrence of heartburn and/or regurgitation symptoms at least several days a month. Survey design analysis for pooled data was performed and multiple regression analysis was conducted to determine the independent risk factors for GERD. RESULTS: The prevalence of GERD in our study was estimated at 21.86% (95% confidence interval:17.4%-36.4%). The mean age of the participants was 49.84 years±9.25 (35-70) and 44.75% of the participants were male. Symptoms of heartburn and regurgitation were reported in 18.65% (n: 29,170) and 6.06% (n: 9,717) of participants, respectively. In the multivariate analysis, several factors were found to be associated with a higher prevalence of GERD: female sex, age >50, current smoking, opium use, weekly consumption of fried foods, frequent consumption of hot tea, less than 6 hours of sleep per night, psychiatric disorders, usage of NSAIDs, and poor oral hygiene, were associated with a higher prevalence of GERD. Conversely, higher education levels and average physical activity were found to be less commonly associated with GERD. CONCLUSION: We found a relatively high prevalence of GERD (21.86%) in this population-based study in Iran. By identifying modifiable risk factors, this research offers opportunities for targeted interventions and lifestyle modifications to reduce the burden of GERD.

RESUMO

Background: Opium use is a significant social and public health issue. There are numerous effects of opium documented as affecting the pancreatobiliary system. The aim of the study was to assess the pancreatobiliary changes in patients with opium addiction by endoscopic ultrasonography (EUS). Methods: During the study period, consecutive patients who were referred for EUS of submucosal upper gastrointestinal lesions were included. The history of opium addiction and clinical symptoms were recorded prospectively. Diameters of the common bile duct (CBD), pancreatic duct (PD), size of the ampulla of Vater, and gallbladder abnormalities were evaluated using EUS. Results: A total of 254 patients (53.1% male, mean age of 55.4±14.2 years) were studied. A history of opium addiction was present in 56 patients (22.0%). Choledocholithiasis was found in two patients (3.6%) and one control (0.5%) patient (P=0.06). Gallbladder stones were found in 13 opium-addict (23.2%) and 16 control (8.1%) patients (P=0.002). The mean diameter of the CBD, size of the ampulla of Vater (P<0.001), and PD (P=0.04) were all significantly greater in patients with opium addiction. Conclusion: Dilation of the biliary and PDs is seen more commonly in patients addicted to opium. However, the clinical implications of these findings need to be further evaluated in future studies.

RESUMO

BACKGROUND: SARS-CoV-2 may affect vital organs. The present study investigated the histopathology of pulmonary and cardiac tissues with clinical correlation in deceased patients with COVID-19. METHODS: We obtained pulmonary and cardiac tissues from 30 deceased patients with COVID-19 in Tehran, Iran, from January to May 2021. Sampling was performed through a percutaneous needle biopsy. After slide preparation, two expert pathologists studied them. We assessed the correlation between clinical and pathological data by Fisher's exact test. RESULTS: The mean age of the patients was 73.8±13.4 years, and the male-to-female ratio was 23/7. The most common underlying disease was hypertension (HTN) in 25 patients (83%). Fifty-five tissue samples were achieved, including 28 pulmonary and 27 cardiac samples. Our results showed that all patients (100%) developed diffuse alveolar damage (DAD), and 26 (93%) developed hyaline membrane formation. The most common phase of DAD was the exudative-proliferative phase in 16 (57.1%). Three cardiac samples (11%) revealed myocarditis, and seven (26%) showed cardiomyocyte hypertrophy. In univariate analysis using Fischer's exact test, myocarditis had significant relationships with C-reactive protein (CRP) levels higher than 80 mg/dL (P=0.008) and elevated cardiac troponin levels higher than two-fold (P=0.01). CONCLUSION: COVID-19 can affect the major vital organs. However, only myocarditis had a significant relationship with the circulating levels of inflammatory factors.
