Physical and functional evaluations in oncological patients elective to medium and large operations.

PURPOSE: To evaluate the risk of sarcopenia on the length of hospital stay and deaths in preoperative cancer patients as well its relation to physical and functional capacity. METHODS: Preoperative patients admitted to the Cancer Hospital of Mato Grosso comprised the sample. Sociodemographic data, lifestyle data, and a questionnaire for sarcopenia screening were collected. Subsequently, total body mass, height, muscle strength, muscle mass, and physical performance were evaluated. The primary, secondary and tertiary outcomes were sarcopenia, length of stay and death, respectively. The data were tabulated and analyzed using the statistical software SPSS (25.0). The significance level was 5%. RESULTS: We observed 12 (7.4%) patients with low muscle strength, 20 (12.3%) patients with low muscle mass, 11 (6.8%) patients with low physical performance, and 18 (11.1%) patients with scores for possible sarcopenia. When the risk of sarcopenia was observed, 44 (27.2%) patients had at least one risk related to muscle disorder. When analyzing the prevalence and association of sarcopenia with sociodemographic variables, we observed that education level was associated with sarcopenia (p = 0.031). In addition, there was an association between preoperative sarcopenia and postoperative death (p = 0.006). Finally, there were important correlations between muscle strength and physical performance (p < 0.05), between muscle strength and the sarcopenia questionnaire (p < 0.001), and between physical performance and the sarcopenia questionnaire (p < 0.05). CONCLUSION: The results suggest the need for counseling and the need to evaluate patients for risk of sarcopenia, since early intervention, such as dietary supplementation and physical exercise, may favor a better postoperative prognosis, possibly corresponding to shorter hospital stays and longer survival and quality of life for patients, especially those who will undergo surgical procedures.

The impacts of COVID-19 pandemic on service delivery and treatment outcomes in people living with HIV: a systematic review.

INTRODUCTION: The COVID-19 epidemic and various control and mitigation measures to combat the widespread outbreak of the disease may affect other parts of health care systems. There is a concern that the COVID-19 pandemic could disrupt HIV services. Therefore, this study aimed to systematically evaluate the effect of the COVID-19 pandemic on service delivery and treatment outcomes in people with HIV. METHODS: In this study, a systematic search was conducted using the keywords in the online databases including Scopus, PubMed, Web of Science, and Cochrane databases. The retrieved articles underwent a two-step title/abstract and full-text review process, and the eligible papers were selected and included in the qualitative synthesis. RESULT: We selected 16 studies out of 529 retrieved records that met the inclusion criteria for this review. Study populations of the selected studies were either HIV-positive patients or HIV clinics and healthcare providers. Most studies were focused on adhering to and obtaining medication and attending clinical appointments and their decrement during the pandemic. Other aspects of HIV care (alternative healthcare settings, viral suppression, psychological care, etc.) were discussed to a lesser extent by the included studies. CONCLUSION: Interruption in in-person visits and medical follow-up services, loss of adherence to treatment, and subsequent increase in mortality due to the COVID-19 pandemic complications in PLHIV have led to growing concerns. Other challenges were psychological disorders such as anxiety and depression, an increase in substance abuse, and a rise in experienced stigma and discrimination. However, the use of telemedicine in some countries helps to alleviate the situation to some extent and is recommended in similar settings in the future.

Current ART, determinants for virologic failure and implications for HIV drug resistance: an umbrella review.

OBJECTIVE: The purpose of this study is to investigate the incidence of determinants for virologic failure and to identify predisposing factors to enhance treatment efficacy. Tackling this global public health issue is the key to reducing the rate of virological failure and increasing the success of treatment for those living with HIV. METHODS: This umbrella review delves into various aspects of current anti-retroviral therapy (ART) which is the primary treatment for human immunodeficiency virus (HIV) infection. Comprehensive searches were conducted in online databases including PubMed, Embase, Scopus, and Web of Science, up to May 26, 2023. Following the screening and selection of relevant articles, eligible articles were included in the data extraction. This study adhered to the PRISMA guideline to report the results and employed the NIH quality and bias risk assessment tool to ensure the quality of included studies. RESULTS: In total, 40 review studies published from 2015 to 2023 were included. The bulk of these studies concurred on several major factors contributing to HIV drug resistance and virological failure. Key among these were medication adherence, baseline and therapeutic CD4 levels, the presence of co-infections, and the advanced clinical stage of the infection. CONCLUSION: The resistance to HIV drugs and instances of determinants for virologic failure have a profound impact on the life quality of those infected with HIV. Primary contributors to this scenario include insufficient adherence to treatment, decreased CD4 T-cell count, elevated viral levels, and certain treatment regimens. Implementing appropriate interventions could address these issues. Sub-Saharan Africa exhibits elevated rates of determinants for virologic failure, attributed to the delay in HIV testing and diagnosis, and late initiation of antiretroviral therapy (ART). It is essential to undertake further research aimed at enhancing the detection of resistance in HIV patients and mitigating viral failure by addressing these underlying causes.

Seroconversion following the first, second, and third dose of SARS-CoV-2 vaccines in immunocompromised population: a systematic review and meta-analysis.

BACKGROUND: Immunocompromised (IC) patients are at higher risk of more severe COVID-19 infections than the general population. Special considerations should be dedicated to such patients. We aimed to investigate the efficacy of COVID-19 vaccines based on the vaccine type and etiology as well as the necessity of booster dose in this high-risk population. MATERIALS AND METHODS: We searched PubMed, Web of Science, and Scopus databases for observational studies published between June 1st, 2020, and September 1st, 2021, which investigated the seroconversion after COVID-19 vaccine administration in adult patients with IC conditions. For investigation of sources of heterogeneity, subgroup analysis and sensitivity analysis were conducted. Statistical analysis was performed using R software. RESULTS: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, we included 81 articles in the meta-analysis. The overall crude prevalence of seroconversion after the first (n: 7460), second (n: 13,181), and third (n: 909, all population were transplant patients with mRNA vaccine administration) dose administration was 26.17% (95% CI 19.01%, 33.99%, I2 = 97.1%), 57.11% (95% CI: 49.22%, 64.83%, I2 = 98.4%), and 48.65% (95% CI: 34.63%, 62.79%, I2 = 94.4%). Despite the relatively same immunogenicity of mRNA and vector-based vaccines after the first dose, the mRNA vaccines induced higher immunity after the second dose. Regarding the etiologic factor, transplant patients were less likely to develop immunity after both first and second dose rather than patients with malignancy (17.0% vs 37.0% after first dose, P = 0.02; 38.3% vs 72.1% after second dose, P < 0.001) or autoimmune disease (17.0% vs 36.4%, P = 0.04; 38.3% vs 80.2%, P < 0.001). To evaluate the efficacy of the third dose, we observed an increasing trend in transplant patients after the first (17.0%), second (38.3%), and third (48.6%) dose. CONCLUSION: The rising pattern of seroconversion after boosting tends to be promising. In this case, more attention should be devoted to transplant patients who possess the lowest response rate.

Cascade of care in people living with HIV in Iran in 2019; how far to reach UNAIDS/WHO targets.

Systematic HIV program evaluation requires looking at all steps of the HIV cascade of care, from diagnosis to treatment outcomes. Our study was carried out to assess the treatment cascade of people living with HIV (PLWH) in Iran in 2019. We used data from the HIV Case Registry System of Iran through December 2019. We estimated the number of PLWH in 2019 by using Spectrum, and then the proportion of them being diagnosed, linked to care, received antiretroviral treatment and suppressed viral load. We estimated that there are 59,314 (UI: 32,685-125,636) PLWH in Iran, of whom 22,054 people (37% of PLWH) were diagnosed. At the end of 2019, of whom, 14,685 (25% of PLWH) people received antiretroviral therapy. Also, of whom 6338 (11% of PLWH) people had viral load suppression by 2019. Our results showed that about one-third of total PLWH were diagnosed, while this defect is somewhat less in children than adults. To reach the 90.90.90 targets Iran needs to developed the current national HIV care guidelines, which recommend best strategies to scale up the case finding and linkage to care among undiagnosed people specifically those who infected by sexual contact in general and key populations as well.

Social Support Associated with Condom Use Behavior Among Female Sex Workers in Iran.

BACKGROUND: Despite the widespread knowledge about social support and health, there is little information about the association between social support and HIV risk behaviors such as condom use among female sex workers (FSWs) in Iran. This study aimed to determine the association between social support and frequency of condom use among FSWs in Tehran, Iran. METHODS: Using mixed sampling methods, we recruited 170 FSWs in Tehran in 2017. We measured self-reported social support by face-to-face interviews using a standardized questionnaire. Linear regression was used to assess the association between socio-demographic characteristics (age, education level, marital status, and place of living), transactional sex characteristics (age at first transactional sex and frequency of transactional sex in the last month), HIV knowledge, social support network characteristics (social network size, duration of tie, intimacy, social support), and condom use behavior. RESULTS: Of the total of 1193 persons in FSW's social networks, 615 (51%) were sexual partners, 529 (44%) were peer sex workers, and 36 (5%) were family members. The participants perceived moderate social support from sexual partners, low from peer sex workers, and very low from family members. Adjusted for individual and other network characteristics, peer sex worker social support (b = 0.28, 95%CI 0.06, 0.50), and family support (b = 1.12, 95%CI 0.028, 2.23) were significantly associated with condom use. CONCLUSION: Family and peer sex worker social support are associated with condom use, but less strongly than HIV knowledge or place of living. However, very few FSWs are socially connected with families. Interventions to promote condom use among this vulnerable population should also consider social and familial support.

Predictors of the chest CT score in COVID-19 patients: a cross-sectional study.

BACKGROUND: Since the COVID-19 outbreak, pulmonary involvement was one of the most significant concerns in assessing patients. In the current study, we evaluated patient's signs, symptoms, and laboratory data on the first visit to predict the severity of pulmonary involvement and their outcome regarding their initial findings. METHODS: All referred patients to the COVID-19 clinic of a tertiary referral university hospital were evaluated from April to August 2020. Four hundred seventy-eight COVID-19 patients with positive real-time reverse-transcriptase-polymerase chain reaction (RT-PCR) or highly suggestive symptoms with computed tomography (CT) imaging results with typical findings of COVID-19 were enrolled in the study. The clinical features, initial laboratory, CT findings, and short-term outcomes (ICU admission, mortality, length of hospitalization, and recovery time) were recorded. In addition, the severity of pulmonary involvement was assessed using a semi-quantitative scoring system (0-25). RESULTS: Among 478 participants in this study, 353 (73.6%) were admitted to the hospital, and 42 (8.7%) patients were admitted to the ICU. Myalgia (60.4%), fever (59.4%), and dyspnea (57.9%) were the most common symptoms of participants at the first visit. A review of chest CT scans showed that Ground Glass Opacity (GGO) (58.5%) and consolidation (20.7%) were the most patterns of lung lesions. Among initial clinical and laboratory findings, anosmia (P = 0.01), respiratory rate (RR) with a cut point of 25 (P = 0.001), C-reactive protein (CRP) with a cut point of 90 (P = 0.002), white Blood Cell (WBC) with a cut point of 10,000 (P = 0.009), and SpO2 with a cut point of 93 (P = 0.04) was associated with higher chest CT score. Lung involvement and consolidation lesions on chest CT scans were also associated with a more extended hospitalization and recovery period. CONCLUSIONS: Initial assessment of COVID-19 patients, including symptoms, vital signs, and routine laboratory tests, can predict the severity of lung involvement and unfavorable outcomes.

Combination of resistance and aerobic exercise for six months improves bone mass and physical function in HIV infected individuals: A randomized controlled trial.

To evaluate the effect of combined resistance and aerobic training (RT+AT) on regional bone mineral density (BMD) and physical performance in people living with HIV (PLWH). Forty PLWH (20 men and 20 women) were randomized into RT+AT group (n = 20; age = 38.3 ± 4.9) or non-exercise control group (n = 20; age = 37.9 ± 5.1). The RT+AT group was required to perform a nonlinear periodized resistance training program targeting large muscle groups followed by 20 min aerobic exercise at 65-80% of maximal heart rate. Participants in RT+AT performed three supervised sessions per week for 6-months, whereas participants in the control group were instructed to continue with their current lifestyle habits. The primary outcome was bone mineral density (lumbar spine (L2-L4), femoral neck, and distal 1/3 radius). Secondary outcomes included physical function, anthropometry, inflammatory markers, and growth factors. The RT+AT group demonstrated a significant increase in BMD at follow-up for the Lumbar spine (L2-L4), femoral neck, and 1/3 radius (all, P < .05), and There were no gender differences in the training response between men and women for any of the BMD regions. Similar findings were also observed for lean body mass, IGF1and Adiponectin (P < .001). We observed a decrease in percent body fat, fat mass, IL-6, TNF-α, and myostatin in the RT+AT group (P < .001). Finally, there was a significant increase in handgrip strength and gait speed for both women and men in the RT+AT group (P < .001). A combination of resistance and aerobic training appears to be a feasible and effective means for counteracting bone loss and improving various inflammatory markers, physical function, and growth hormones in PLWH.

Olfactory and gustatory dysfunctions due to the coronavirus disease (COVID-19): a review of current evidence.

INTRODUCTION: It is reported that coronavirus disease (COVID-19) can affect the sense of smell and taste of infected people. The pathobiology of this virus is still incompletely known, and it is therefore important to explore the impact of COVID-19 infections on olfactory and gustatory functions. We aimed to review current evidence on olfactory and gustatory dysfunctions caused by COVID-19. METHODS: This study was a narrative review performed in 2020 to investigate the olfactory and gustatory dysfunctions of the COVID-19. We searched eight keywords in six databases to determine the related documents on the main objective of the study. To discover studies meeting the inclusion criteria, the authors screened the titles and abstracts of the identified articles. The appropriate studies were included and their results were discussed to make the final selection. RESULTS: We have studied 24 current articles on the olfactory and gustatory dysfunctions due to COVID-19. A review of current studies has shown that we have a surge in the spread of olfactory and gustatory dysfunctions that happened during the epidemic of COVID-19 infection. Most studies (95.8%) have confirmed the symptoms of anosmia in patients with SARS-CoV-2 infection. A review of current studies showed that, in addition to anosmia, evidence of ageusia and dysgeusia (parageusia) was also seen in patients with COVID-19. CONCLUSION: The results of our study support recent reports that SARS-CoV-2 may infect oral and nasal tissues and cause olfactory and gustatory dysfunctions. These findings may aid future research on the diagnosis, prevention, and treatment of COVID-19 consequences.

Barriers and associated factors for adequate antenatal care among Afghan women in Iran; findings from a community-based survey.

BACKGROUND: Almost a third of Afghan women living in Iran are at childbearing age. Antenatal care (ANC) is an inextricable part of healthy pregnancy and could prevent the adverse birth outcomes. Almost 97% of Iranian expectant women are receiving adequate ANC (4 or more visits). However, the situation for pregnant Afghan women is unclear. Some studies indicated low access to ANC among Afghan women. In the present study, we aimed to explore the sociodemographic factors and potential barriers associated with adequate ANC among Afghan women in Iran. METHODS: A cross sectional study was conducted between June 2019 and August 2019. Using time location sampling (TLS), we recruited 424 Afghan women aged 18-45 years old at three health centers in south region of Tehran. The data were collected on sociodemographic characteristics and the reported reasons for inadequate ANC using a questionnaire and analyzed applying bivariate, and multivariate analyses. Factor analysis was performed to reduce the number of potential reasons for inadequate ANC in order to improve the precision of regression analysis. RESULTS: Almost a third of Afghan women in this study had adequate ANC (≥ 8 visits). The women in older age group, those with higher education and family income, women with longer length of stay, those of legal status were more likely to have adequate ANC. In multivariate analysis, the poor knowledge and attitude toward ANC (AOR = 0.06; 95% CI [0.03-0.15]), the poor quality of services (AOR = 0.17 95% CI [0.07-0.41]); and to some extent, the difficulties in access (AOR = 0.33; 95% CI [0.11-1.00]) were the main obstacles toward adequate ANC among the study population. CONCLUSION: Our study emphasized the important role of the personal knowledge and attitude toward ANC with adequate antenatal care among Afghan women in Iran. This could be addressed by well-oriented interventions and health education for Afghan women. The collaboration between central government with international agencies should be directed toward enhancing the social support, promoting the awareness and knowledge, and expanding the safety net services to improve the access and quality care among Afghan women in Iran.

"It is good, but I can't afford it " potential barriers to adequate prenatal care among Afghan women in Iran: a qualitative study in South Tehran.

BACKGROUND: An estimated 96% of registered refugees in Iran are Afghan. Almost half of them are young women at the reproductive age. The adequate maternity care is crucial for healthy pregnancy. There is limited knowledge regarding the access and adequacy of maternity care among Afghan women in Iran. The reports from ministry of health (MOH) implicate higher prevalence of perinatal complications in Afghan population. This mainly attributed to the inadequate prenatal care during pregnancy. Therefore, this paper explores the potential barriers to prenatal care among Afghan women in Iran. METHODS: Using convenience sampling, thirty pregnant Afghan women were recruited at three community health centers with the highest number of Afghan visitors in Tehran, the capital city of Iran. Data were collected through face-to-face interviews in Persian language using an interview guide. The interviewers were two bilingual Afghan graduate midwifery students. Each interview lasted for an hour. The questions regarding the concerns and experienced obstacles in seeking prenatal care were asked. The interviews were transcribed into original language (Persian) and analyzed using content analysis and further translated back into English. The main themes were extracted grouping the similar codes and categories after careful consideration and consensus between the researchers. RESULTS: The financial constraints and lack of affordable health insurance with adequate coverage of prenatal care services, particularly the diagnostic and screening tests, were the most frequent reported obstacles by Afghan women. In addition, personnel behavior, transportation issues, stigma and discrimination, cultural concerns, legal and immigration issues were also mentioned as the source of disappointment and inadequate utilization of such services. CONCLUSIONS: The findings of present study emphasize the necessity of available and most importantly, affordable prenatal care for Afghan women in Iran. Providing an affordable health insurance with adequate coverage of prenatal and delivery services, could reduce the financial burden, facilitate the access, and ensure the maternal and child health in this vulnerable population. The issues of fear and concern of deportation must be removed for at least illegal Afghan mothers to ensure their access to maternity care and improve the health of both mother and offspring.

Effect of 8 Weeks of Hospital-Based Resistance Training Program on TCD4+ Cell Count and Anthropometric Characteristic of Patients With HIV in Tehran, Iran: A Randomized Controlled Trial.

Ghayomzadeh, M, SeyedAlinaghi, S, Shamsi, MM, Rezaei, S, Earnest, CP, Akbarnejad, S, Taj, L, Mohraz, M, Navalta, JW, Ghasemi, P, and Voltarelli, FA. Effect of 8 weeks of hospital-based resistance raining program on TCD4+ cell count and anthropometric characteristic of patients with HIV in Tehran, Iran: A randomized controlled trial. J Strength Cond Res 33(4): 1146-1155, 2019-We examined the effects of an 8-W circuit resistance training (RES) program using elastic bands and body weight on TCD4+ cell counts and anthropometry in patients with HIV. Patients (N = 21) receiving antiretroviral therapy were randomly assigned to resistance training (RES; n = 14) or control (CON; n = 7) groups. RES (3/W) consisted of training with elastic bands and bodyweight training focusing on major muscle groups. CON received standard care. Statistical analyses were performed using general linear models adjusted for age, sex, length of infection, and respective baseline measures. The primary outcome was TCD4+, and secondary outcomes were anthropometry indices. Tertiary assessments explored Pearson correlations surrounding the relationship between changes in anthropometry and TCD4+. We observed significant increases in TCD4+ count accompanying RES training (105.50 cells·mm, 95% confidence interval [CI], 47.42-163.59), whereas CON significantly decreased (-41.01 cells·mm, 95% CI, -126.78 to 44.76). Significant between-group differences were noted (p < 0.02; n = 0.42). We also observed significant reductions in fat mass for RES (1.18 kg, 95% CI = 1.80 to -0.56) vs. increased fat mass for CON (1.21 kg, 95% CI, 0.31 to 2.11). Significant between-group differences were noted (p = 0.001, n = 0.64). Similar effects were noted for lean body mass. No significant changes were observed for body mass. Significant correlations were observed for fat mass (r = -0.699, p = 0.001) and lean mass (r = 0.553, p = 0.017), but not body mass (r = -0.390, p = 0.109) vs. changes in TCD4+. Our results suggest that the RES program used in this study is effective for improving TCD4+ status and body composition in patients with HIV.

Fabrication of long-acting insulin formulation based on poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) nanoparticles: preparation, optimization, characterization, and in vitro evaluation.

The purpose of this research was the fabrication, statistical optimization, and in vitro characterization of insulin-loaded poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) nanoparticles (INS-PHBV-NPs). Nanopar-ticles were successfully developed by double emulsification solvent evaporation method. The NPs were characterized for particle size, entrapment efficiency (EE%), and polydispersity index (PDI). The NPs also were characterized by scanning electron microscopy (SEM), Fourier transformed infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and circular dichroism (CD). The optimum conditions were found to be 1.6% polyvinyl alcohol (PVA), 0.9% of PHBV, and 15 mg/ml of insulin with the aid of the Box-Behnken experimental design results. The optimized NPs showed spherical shape with particle size of 250.21 ± 11.37 nm, PDI of 0.12 ± 0.01, and with EE% of 90.12 ± 2.10%. In vitro drug release pattern followed Korsmeyer-Peppas model and exhibited an initial burst release of 19% with extended drug release of 63.2% from optimized NPs within 27 d. In conclusion, these results suggest that INS-PHBV-NPs could be a promising candidate for designing an injectable sustained release formulation for insulin.

Evaluation of Acquired HIV Drug Resistance among People Living with HIV Who Have Taken Antiretroviral Therapy for 9-15 Months in 14 Triangular Clinics in Iran, 2015-2016.

AIMS: The aim of this study was to evaluate drug resistance patterns among Iranian people living with HIV who have taken antiretroviral therapy for 9-15 months. METHODS: A cross-sectional study was conducted between December 2015 and May 2016. Two hundred fifty-two blood samples were collected from all eligible HIV-infected patients at fourteen healthcare settings, located in major provinces in Iran. The samples were examined for presence of drug resistance strains and viral load level. Moreover, a phylogenetic tree, using neighbor joining, was constructed and HIV subtypes were determined. RESULTS: The most common subtypes were CRF35-AD (47.6%) and A1 (42.8%), followed by 45_CPX (4.8%) and C (4.8%). The resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs), nucleoside reverse transcriptase inhibitors (NRTIs), and protease inhibitors was reported as 19.2, 19.2, and 10.3%, respectively. M184I/V mutation was the most frequent (31.6%) mutation among NRTI-based regimens. Moreover, K103E/N was the most frequent (34.2%) NNRTI mutation. CONCLUSIONS: This is the first study to illuminate the emergence of the CPX genotype among Iranian patients. The drug resistance rate of NNRTIs was similar to that of NRTIs. By assessing drug resistance, it is possible to evaluate the efficacy of treatment and patient adherence to treatment.

Antiretroviral drug resistance among antiretroviral-naïve and treatment experienced patients infected with HIV in Iran.

Resistance to antiretroviral therapy (ART) threatens the success of programs to reduce HIV morbidity and mortality, particularly in countries with few treatment options. In the present study, genotype and phenotype data from ART-naïve and experienced hospitalized patients infected with HIV in Tehran, Iran were used to assess the prevalence and types of transmitted (TDR) and acquired drug resistance (ADR) mutations. All 30 participants naïve to ART and 62 of 70 (88.6%) participants receiving ART had detectable viral loads. Among participants receiving ART with sequencing data available (n = 62), 36 (58.1%) had at least one drug resistance mutation; the most common mutations were K103N (21.0%), M184V (19.4%), and the thymidine analogue mutations. Seven (11.3%), 27 (43.5%), and two (3.2%) of these participants had resistance to one, two, and three drug classes, respectively. High-level resistance to efavirenz (EFV) was more common among participants on EFV-based regimens than high-level lopinavir/ritonivar (LPV/r) resistance among those on LPV/r-based regimens (55.3% vs. 6.7%, P < 0.0001). Two (6.7%) antiretroviral-naïve participants had K103N mutations. These findings document an alarmingly high frequency of multiple HIV drug class resistance in Iran, confirm the presence of TDR, and highlight the need for systematic viral load monitoring and drug resistance testing, including at diagnosis. Expanded access to new antiretroviral medications from additional drug classes is needed.

The effectiveness of discharge planning on the knowledge, clinical symptoms and hospitalisation frequency of persons with schizophrenia: a longitudinal study in two hospitals in Tehran, Iran.

AIMS AND OBJECTIVES: To investigate the effectiveness of discharge planning on the knowledge, clinical symptoms and frequency of hospitalisation of persons with schizophrenia. BACKGROUND: Discharge planning is associated with decreases in the duration of hospitalisation, readmission to hospitals and decreases in medical costs. Yet, there is little known about the effectiveness of discharge planning among persons with schizophrenia in Iran. DESIGN: Longitudinal clinical trial. METHODS: In this longitudinal clinical trial, 46 persons with schizophrenia admitted to psychiatric hospitals were selected and classified into either intervention or control groups. For the intervention group, the discharge planning was designed using the nursing process model. The intervention was implemented across six sessions in the hospital and six sessions in patient's home (up to three months after discharge). Friedman test, independent t-tests, chi-squared test, Mann-Whitney U-test and Mc-Nemar's test were used to analyse demographic characteristics, knowledge scores, clinical symptoms and the frequency of hospitalisation. RESULTS: The intervention group demonstrated improved clinical symptoms between the time of discharge and three months after discharge and had higher knowledge levels compared with the control group. In addition, the frequency of patients' hospitalisation preintervention and three months postintervention was statistically significantly lower in the intervention group, while no such differences were found among the control group during this same time period. CONCLUSION: This study suggests that there are a number of advantages to discharge planning including an increase in the knowledge of patients, a decline in clinical symptoms and a reduction in the frequency of admission to hospitals. RELEVANCE TO CLINICAL PRACTICE: Due to high frequency of relapse, rehospitalisation and high remedial costs of persons with schizophrenia, it is important to consider discharge planning as a therapeutic approach for patients.

Managing Hepatotoxicity Caused by Anti-tuberculosis Drugs: A Comparative Study of Approaches.

BACKGROUND: Tuberculosis (TB) is one of the oldest and most well-known diseases that has been associated with humans for many years and remains a global health challenge today. Timely diagnosis and proper treatment are crucial for controlling and preventing the spread of the disease. While anti-TB drugs offer many benefits, inadequate monitoring can lead to a range of side effects, including hepatotoxicity, which is a major concern and can cause treatment discontinuation. The aim of this study was to determine the approach to the hepatotoxicity of anti-TB drugs and to investigate potential relationships between demographic factors, underlying medical conditions, and successful retreatment outcomes for hepatotoxicity induced by anti-TB drugs. METHODS: For this study, we reviewed the medical records of patients who experienced hepatotoxicity due to anti-TB treatment and were admitted to the infectious ward of Imam Khomeini Hospital between April 2015 and February 2019. The data were collected using a questionnaire. RESULTS: The findings indicated that the female gender, weight loss at the beginning of hospitalization, hepatitis C virus, hepatitis B virus (HBV), heart disease, and high levels of aspartate aminotransferase (AST) and alanine transaminase (ALT) at the beginning of hepatotoxicity are risk factors for failure to the retreatment of hepatotoxicity. There were two different approaches to the anti-TB retreatment regimen. The first approach involved gradually starting the drugs in full dose, while the second approach encompassed starting the drugs in the minimum dose and then increasing to the maximum dose. The results demonstrated no significant difference between the two approaches to managing hepatotoxicity induced by anti-TB drugs. CONCLUSION: Drug-induced hepatotoxicity is a common occurrence that often results in treatment discontinuation. Understanding the prevalence of this complication and identifying appropriate methods of rechallenge treatment is crucial to reducing complications and mortality rates.

The prognostic significance of insulin resistance in COVID-19: a review.

Objectives: Emerging publications indicate that diabetes predisposes patients with COVID-19 to more severe complications, which is partly attributed to inflammatory condition. In the current review, we reviewed recent published literature to provide evidence on the role of insulin resistance (IR) in diabetes, the association between diabetes and COVID-19 severity and mortality, the impact of COVID-19 infection on incident new-onset diabetes, mechanisms responsible for IR in COVID-19 patients, and the predictive value of different surrogates of IR in COVID-19. Method: The literature search performs to find out studies that have assessed the association between IR surrogates and morbidity and mortality in patients with COVID-19. Results: We showed that there is a bulk of evidence in support of the fact that diabetes is a potent risk factor for enhanced morbidity and mortality in COVID-19 patients. COVID-19 patients with diabetes are more prone to remarkable dysglycemia compared to those without diabetes, which is associated with an unfavourable prognosis. Furthermore, SARS-COV2 can make patients predispose to IR and diabetes via activating ISR, affecting RAAS signaling pathway, provoking inflammation, and changing the expression of PPARÉ£ and SREBP-1. Additionally, higher IR is associated with increased morbidity and mortality in COVID-19 patients and different surrogates of IR can be utilized as a prognostic biomarker for COVID-19 patients. Conclusion: Different surrogates of IR can be utilized as predictors of COVID-19 complications and death.
