RESUMO
BACKGROUND: The success of the strabismus surgery can hinge on several factors. One of these factors is refractive condition like hyperopia or myopia. Our study seeks to evaluate the surgical outcomes in patients with esotropia and myopia. METHODS: This case-control study encompassed all surgical cases of esotropia at Torfe and Negah Hospital between 2016 and 2021, which satisfied our specified inclusion criteria. The initial variables from electronic medical records were collected, including demographic, clinical, and surgery-related factors. At the final follow-up appointment, the level of eye deviation, both at distance and near, was recorded. We considered the operation a "success" for patients with a post-surgery distance eye deviation of 10(Pd) or less. Patients with greater deviation were classified as surgery failure. Statistical analyses were executed using SPSS software (version 16.0), and a P-value less than 0.05 was considered significant. RESULTS: Of the 194 patients evaluated, 112 were incorporated into the study. Surgical failure was observed in 14.29% of myopic patients, 29.79% of hyperopic patients, and 31.82% of emmetropic patients. The myopia group displayed a 0.19 odd ratio for surgical failure compared to the combined hyperopia and emmetropia groups, not statistically significant (OR: 0.19, CI 95%: 0.03-1.02). Additionally, patients diagnosed with Lateral Rectus Under-action were found to be 6.85 times more likely to experience surgery failure(OR: 6.85, CI 95%: 1.52-30.94). An elevated risk of surgical failure was also identified in patients who underwent Inferior Oblique Weakening procedure, indicated by a 3.77-fold increase in the odds ratio for failure(OR: 3.77, CI 95%: 1.08-13.17). CONCLUSION: In our study, despite numerical disparities, there was no statistical difference among the success rates of all esotropia patients with different refractive errors. The patients with LRUA or IOOA showed lower success rates. Myopic patients had higher post-op overcorrection with lower reoperation rates compared to hyperopic or emmetropic patients.

PURPOSE: The purpose of this study was to investigate the donor risk factors and environmental conditions associated with poor-quality corneas using the database of the Central Eye Bank of Iran over 4 years. METHODS: This cohort study was conducted on the recorded data of all donated corneas at the Central Eye Bank of Iran database from March 2018 to March 2022. Donors' characteristics and tissue variables were extracted from the database. The final corneal quality was determined based on slitlamp biomicroscopic observations and the results of specular microscopy. Environmental variables were also obtained from reliable resources. Risk factors for poor-quality corneas were calculated using logistic mixed-effect regression analysis. All analyses were performed with STATA 17.0. The significance level of 0.05 was considered for all the analyses. RESULTS: The data of 20,625 eyes of 10,601 donors were evaluated. We found that donor age had an inverse correlation with endothelial cell density (r = -0.28, P < 0.001). The trend of donated corneal poor quality decreased between 2018 and 2021. Several factors, including intoxication (odds ratio [OR] = 1.29), obesity (OR = 1.34), diabetes mellitus (OR = 1.63), hypertension (OR = 1.52), and pseudophakic eyes (OR = 1.56), were associated with the poor quality of donated corneal tissues. The outdoor temperature over 26°C was associated with higher odds of poor corneal quality (OR = 1.31), whereas high relative humidity decreased the odds of poor corneal quality (OR = 0.82). CONCLUSIONS: This study revealed that the cause of donor death, obesity, donor comorbidities, pseudophakia, and environmental factors could affect the corneal quality and make the donated corneas less suitable for transplantation.
RESUMO
INTRODUCTION: This study explores the trend of urolithiasis in various countries and categorizes the countries in terms of how their urolithiasis incidence rate has changed over time. METHODS: The incidence rate of urolithiasis in 204 countries from 1990 to 2019, extracted from the Global Burden of Disease study, has been analyzed. RESULTS: According to the results, all regions had experienced an increasing trend in urolithiasis rate, except for Eastern Europe, Central Europe, and Southeast Asia regions (decreasing rates of -71.4, -56.2, and -9.2 per 100000, respectively). Moreover, the Caribbean region had the highest increasing trend of urolithiasis rates, and Central Asia was in the next rank (increasing rate of 48.3 and 34.3 per 100,000, respectively, p-value < .05). Also, African regions revealed significant increasing trends over time (p-value < 0.05). The outstanding findings in cluster analysis showed that Afghanistan, Andorra, and Comoros had the most decreasing trend in urolithiasis rates over time (decreasing rate of -128.2 per 100000, p-value < .001). Cuba, Cyprus, Czechia, the Democratic People's Republic of Korea, Denmark, and Djibouti were in the next rank in terms of decreasing rate (decreasing rate of -92.3 per 100000, p-value < .001). In addition, urolithiasis rates in Congo, Eswatini, Gabon, and Grenada have the most increasing trend (increasing rate of 116.1 per 100000, p-value < .001). CONCLUSION: The trend of urolithiasis rates was significantly increased in most countries, and Congo, Eswatini, Gabon, and Grenada had the highest trend among others. Also, Afghanistan, Andorra, and Comoros revealed the most decreasing rates, and the trend has dropped remarkably in several other countries.

PURPOSE: Concomitant kidney diseases raise the mortality rate due to the SARS-CoV-2 virus as an independent factor. Although a qualitative PCR test's result is sufficient for diagnosis, Cycle threshold value may present relevant information to the physicians in providing faster treatment in patients with chronic conditions, including kidney diseases, to prevent morbidity and subsequent mortality. Thus, the present study was conducted to determine the relationship between the Cycle threshold value and clinical outcomes in renal patients with the coronavirus 2019. METHODS: This retrospective study was conducted on renal patients with the coronavirus 2019 infection admitted to Labbafinejad Hospital in Tehran, the capital of Iran, within a period of one year, from late February 2020 to February 2021. Data were collected per the prepared checklist. Cycle threshold values were measured by performing PCR on nasopharynx and oropharynx swab samples of patients. RESULTS: According to the adjusted analysis, having high viral load increased the odds of in-hospital mortality (aOR = 11.65, 95% CI 3.93-34.54), ICU admission (aOR = 5.49, 95% CI 2.16-13.97), and invasive ventilation (aOR = 7.18, 95% CI 2.61-19.74). Having high viral load also increased the odds of O2 therapy (aOR = 3.08, 95% CI 0.79-12.01), although the difference was not statistically significant (P = 0.105). CONCLUSION: Cycle threshold value was a significant predictor of mortality in renal patients. Nevertheless, further studies are required on how to render optimal use of the Cycle threshold value, given that the quality of the test sample and the different groups of patients under study affect the effectiveness of this marker in predicting disease severity.

This study aimed to determine the relationship of death anxiety with quality of life and social support in hemodialysis patients. This cross-sectional research was conducted on 226 patients with chronic renal failure. The results indicated that the means and standard deviations of MSPSS, QoL, and death anxiety of patients were 57.4 ± 10.1, 28.8 ± 5.9, and 42.5 ± 4.1, respectively. A significant negative correlation was found between QoL scores and death anxiety in hemodialysis patients (p = 0.007, r = -0.179). However, there was no statistically significant relationship between MSPSS scores and patients' death anxiety. The total score of patients' death anxiety decreased with increasing the total QoL score (p < 0.001, b = -0.18). Different variables that can affect death anxiety and QoL should be identified in the patient examination process. Also, the health care system should consider necessary planning to increase the QoL and reduce death anxiety.
RESUMO
Background: Appropriate respiratory support is crucial for improving the clinical outcomes of critically ill patients infected with the SARS-CoV-2 virus. This study aimed to investigate the different modalities of respiratory support and clinical outcomes in patients with COVID-19 in intensive care units (ICUs). Materials and Methods: In a retrospective study, we enrolled 290 critically ill COVID-19 patients who were admitted to the ICUs of four hospitals in Mazandaran, northern Iran. Data were extracted from the medical records of all included patients, from December 2019 to July 2021. Patients' demographic data, symptoms, laboratory findings, comorbidities, treatment, and clinical outcomes were collected. Results: 46.55% of patients died. Patients with ≥2 comorbidities had significantly increased odds of death (OR=5.88, 95%CI: 1.97-17.52, P=0.001) as compared with patients with no comorbidities. Respiratory support methods such as face mask (survived=37, deceased=18, P=0.022), a non-rebreather mask (survived=39, deceased=12, P<0.001), and synchronized intermittent mandatory ventilation (SIMV) (survived=103, deceased=110, P=0.004) were associated with in-hospital mortality. Duration of respiratory support in nasal cannula (survived=3, deceased=2, P<0.001), face mask (survived=3, deceased=2, P<0.001), a non-rebreather mask (survived=3, deceased=2, P=0.033), mechanical ventilation (survived=5, deceased=6, P<0.019), continuous positive airway pressure (CPAP) (survived=3, deceased=2, P<0.017), and SIMV (survived=4, deceased=5, P=0.001) methods were associated with higher in-hospital mortality. Conclusion: Special attention should be paid to COVID-19 patients with more than two comorbidities. As a specific point of interest, SIMV may increase the in-hospital mortality rate of critically ill patients with COVID-19 connected to mechanical ventilation and be associated with adverse outcomes.
RESUMO
AIM: To evaluate the degree of CD3, CD20, Th17, and Tregs infiltration in kidney biopsy of the patients with acute cellular rejection and the possible relation with graft outcome. MATERIALS AND METHODS: In this retrospective study, fifty patients with Acute T Cell-Mediated Rejection (ATCMR) were enrolled. Previous and one year clinical follow-up data were collected. The kidney specimens were evaluated for infiltration of CD3, CD20, FOXP3, and Th17 with IHC. According to the serum creatinine level in one-year follow-up of the patients after rejection therapy and function of the transplanted organ from the day admitted into the hospital, they were respectively categorized in Stable graft function versus impaired graft function; appropriate response to treatment versus failure to response. RESULTS: Treg (P = 0.96) and Th17 (P = 0.24) cells were more in the unstable group than the stable group, but the difference wasn't significant. On the other hand, the FOXP3/Th17 ratio was higher in the stable group (P = 0.22). Moreover Treg (P = 0.1) and Th17 (P = 0.15) were higher in failure to response group, but FOXP3/Th17 was higher in proper response group (P = 0.8). CONCLUSION: From the results, it can be concluded that TH17 infiltration has a more significant effect on graft outcome and response to rejection therapy.

INTRODUCTION: Cardiovascular disease is considered as the main cause of mortality and morbidity in HD-patients and AS is a fundamental cause. This study was conducted to investigate whether intradialytic BP changes can use as a surrogate clinical marker. METHODS: Fifty-one patients on maintenance hemodialysis, for at least 12 hours per week, were included in a prospective cohort study. Intradialytic BP was measured using validated automated device. PWV was performed to assess Augmentation Index (AIx) as marker of arterial stiffness. All measurements were repeated in alive individuals after 5 years of follow-up. Patients with 5% reduction of intradialytic BP were considered as HD-responsive and Several statistical analyses were employed based on responsiveness to HD. RESULTS: After 5-year follow-up the findings demonstrated BP response to HD was an important and independent determinant of mortality (P < .05). Augmentation index (AIx) (P < .05), heart rate (P < .05), and calcium phosphate product (P < .05) as well as log PTH (P < .05) were significantly different between two responsive and non-responsive to HD. Pearson's Correlation studies revealed a significant relationship between the BP response to HD and heart rate (r = 0.4, P < .05), LVEF (r = -0.4, P < .05) and PTH (r = -0.3, P < .05). BP response to HD and log-PTH remained significant even after age and gender adjustment (P < .05). CONCLUSION: BP-response to HD can use as a clinical and surrogate marker of AS which is significantly associated with mortality and LVEF. Arterial stiffness and intradialytic BP can predict the changes in Ejection Fraction (EF). DOI: 10.52547/ijkd.6810.

INTRODUCTION: Continuous renal replacement therapy (CRRT) is an effective dialysis method in critically ill patients. Citrate and heparin are commonly used as anticoagulants to prevent premature circuit clotting. The aim of this study was to evaluate the safety and efficacy of using low dose systemic heparin while on CRRT in liver transplant recipients. METHODS: We retrospectively evaluated and analyzed data from 29 liver transplant recipients undergoing CRRT in the postoperative course in this cross-sectional study. Numerous variables were recorded, such as coagulation parameters, duration of intensive care unit (ICU) stay, duration of dialysis, heparin dose, circuit life span, and anticoagulant complications. RESULTS: Out of 29 recipients, there were 16 (55%) female and 13 (45%) male. All participants underwent whole organ liver transplantation with a median age of 45 years. Overall, 98 successful dialysis sessions were recorded in this study with a mean circuit life span of 36 hours. Mean ± SD duration of CRRT for each recipient was 4.8 ± 3.1 days. The median total dose of heparin used for each recipient was 25,000 units , and the median dose of heparin per-day for each recipient was about 3,300 units. There were no episodes of anticoagulant-related bleeding complications. Thirteen (13.2%) episodes of premature circuit clotting occurred. We found a significant association between the first dose and total dose of heparin usage with first postoperative INR and PTT level (P < .05, P < .05, P < .001, and P < .05). CONCLUSION: In liver transplant recipients, low dose heparin during CRRT for patency of circuit is well tolerated.

INTRODUCTION: The recommended position for measuring Intra-Abdominal Pressure (IAP) is the supine position. However, patients put in this position are prone to Ventilator-associated pneumonia. This study was done to evaluate the relationship between bed head angle and IAP measurements of intubated patients in the intensive care unit. METHODS: In this clinical trial, seventy-six critically ill patients under mechanical ventilation were enrolled. IAP measurement was performed every 8 hours for 24 hours using the KORN method in three different degrees of the head of bed (HOB) elevation (0 ° , 15 ° , and 30 ° ). Bland-Altman analysis was performed to identify the bias and limits of agreement among the three HOBs. According to World Society of the Abdominal Compartment Syndrome (WSACS), we can consider two IAP techniques equivalent if a bias of <1 mmHg and limits of agreement of - 4 to +4 were found between them. Data were analyzed using SPSS statistical software (v. 19), and the significance level was considered as 0.05. RESULTS: The prevalence of intra-abdominal hypertension was 18.42%. Mean ± standard deviation (SD) of IAP were 8.44 ± 4.02 mmHg for HOB angle 0°, 9.58 ± 4.52 for HOB angle 15 ° , and 11.10 ± 4.73 for HOB angle 30o (p = 0.0001). The IAP measurement bias between HOB angle 0°and HOB angle 15° was 1.13 mmHg. This bias was 2.66 mmHg between HOB angle 0° and HOB angle 30°. CONCLUSION: Elevation of HOB angle from 0 to 30 degree significantly increases IAP. It seems that the measurement of IAP at HOB angle 15° was more reliable than 30°.
RESUMO
BACKGROUND: The outbreak of COVID-19 is an unprecedented challenge to the health systems in Iran. We aimed to assess the psychological impact of this outbreak on nurses in the hospitals of Guilan University of Medical Sciences that is one of the top provinces of incidence of COVID-19. METHODS: In a web-based cross-sectional study, 441 nurses working were selected from the hospitals, from 7 to 12 April 2020. Anxiety and depression were measured using the Generalized Anxiety Disorder-7 and the Patient Health Questionnaire-9, respectively. Simple and multiple logistic regression models were used to identify the factors related to anxiety and depression. RESULTS: The majority were in contact with suspected or confirmed COVID-19 cases (93.4%) and their relatives had been infected with COVID-19 (42%). The mean of anxiety-7 and depression total scores were 8.64 ± 5.60 and 8.48 ± 6.19, respectively. Female (OR = 3.27, 95% CI = 1.01-10.64), working in COVID-19 designated hospital (OR = 1.82, 95% CI = 1.13-2.93), being suspected with COVID-19 infection (OR = 2.01, 95% CI = 1.25-3.26), and insufficient personal protective equipment (OR = 2.61, 95% CI = 1.68-4.06) were associated with anxiety. Depression was significantly associated with female sex (OR = 4.62, %95 CI = 1.24-17.16), having chronic disease (OR = 2.12, 95% CI = 1.20-3.74), being suspected or confirmed with COVID-19 infection (OR = 3.44, 95% CI = 2.11-5.59, and OR = 2.21, 95% CI = 1.04-4.70, respectively), and insufficient personal protective equipment (OR = 1.86, 95% CI = 1.19-2.91). CONCLUSION: The finding declares healthcare workers are at high risk for mental illness. Continuous supervision of the psychological consequences following infectious diseases outbreaks should be a part of the preparedness efforts of health care systems.
