Afghan refugees in Iran, estimated at over 5 million, represent a large vulnerable population whose attitudes towards COVID-19 vaccination are cru

Background: Multi-organ dysfunction syndrome and multi-organ failure are the leading causes of late death in patients sustaining severe blunt trauma. So far, there is no established protocol to mitigate these sequelae. This study assessed the effect of hemoperfusion using resin-hemoadsorption 330 (HA330) cartridges on mortality and complications such as acute respiratory distress syndrome (ARDS) and systemic inflammatory response syndrome (SIRS) among such patients. Methods: This quasi-experimental study recruited patients ≥ 15 years of age with blunt trauma, injury severity score (ISS) ≥ 15, or initial clinical presentation consistent with SIRS. They were divided into two groups: the Control group received only conventional acute care, while the case group received adjunctive hemoperfusion. P-values less than 0.05 were statistically significant. Results: Twenty-five patients were included (Control and Case groups: 13 and 12 patients). The presenting vital signs, demographic and injury-related features (except for thoracic injury severity) were similar (p > 0.05). The Case group experienced significantly more severe thoracic injuries than the Control group (Thoracic AIS, median [IQR]: 3 [2–4] vs. 2 [0–2], p = 0.01). Eleven and twelve patients in the Case group had ARDS and SIRS before the hemoperfusion, respectively, and these complications were decreased considerably after hemoperfusion. Meanwhile, the frequency of ARDS and SIRS did not decrease in the Control group. Hemoperfusion significantly reduced the mortality rate in the Case group compared to the Control group (three vs. nine patients, p = 0.027). Conclusions: Adjunctive Hemoperfusion using an HA330 cartridge decreases morbidity and improves outcomes in patients suffering from severe blunt trauma.

Since the pandemic began in December 2019, SARS-Cov2 has accentuated the wide gap and disparities in socioeconomic and healthcare access at individual, community, country, and regional levels. More than two years into the current pandemic, up to three-fourths of the patients are reporting continued signs and symptoms beyond the acute phase of COVID-19, and Long COVID portends to be a major challenge in the future ahead. With a comprehensive overview of the literature, we found that most studies concerning long COVID came from high and upper-middle income countries, and people of low-income and lower-and-middle income regions and vulnerable groups with comorbid conditions have been neglected. Apart from the level of income, there is a significant geographical heterogeneity in investigating the Post-Acute Sequelae of COVID-19 (PASC) or what we call now, long COVID. We believe that these recognizing health disparities is crucial from equity perspective and is the first step toward global health promotion.

The aim of this study was to investigate the COVID-19 vaccination acceptance rate and its determinants among healthcare workers in a multicenter study. This was a cross-sectional multi-center survey conducted from February 5 to April 29, 2021. The questionnaire consisted of 26 items in 6 subscales. The English version of the questionnaire was translated into seven languages and distributed through Google Forms using snowball sampling; a colleague in each country was responsible for the forward and backward translation, and also the distribution of the questionnaire. A forward stepwise logistic regression was utilized to explore the variables and questionnaire factors tied to the intention to COVID-19 vaccination. 4630 participants from 91 countries completed the questionnaire. According to the United Nations Development Program 2020, 43.6 % of participants were from low Human Development Index (HDI) regions, 48.3 % high and very high, and 8.1 % from medium. The overall vaccination hesitancy rate was 37 %. Three out of six factors of the questionnaire were significantly related to intention to the vaccination. While ‘Perceived benefits of the COVID-19 vaccination’ (OR: 3.82, p-value<0.001) and ‘Prosocial norms’ (OR: 5.18, p-value<0.001) were associated with vaccination acceptance, ‘The vaccine safety/cost concerns’ with OR: 3.52, p-value<0.001 was tied to vaccination hesitancy. Medical doctors and pharmacists were more willing to take the vaccine in comparison to others. Importantly, HDI with OR: 12.28, 95 % CI: 6.10-24.72 was a strong positive determinant of COVID-19 vaccination acceptance. This study highlighted the vaccination hesitancy rate of 37 % in our sample among HCWs. Increasing awareness regarding vaccination benefits, confronting the misinformation, and strengthening the prosocial norms would be the primary domains for maximizing the vaccination coverage. The study also showed that the HDI is strongly associated with the vaccination acceptance/hesitancy, in a way that those living in low HDI contexts are more hesitant to receive the vaccine.

Purpose: We aim to review our experience of transperitoneal laparoscopic ureterolithotomy (TPLU) for proximal ureteric stone more than 15 mm. Patients and methods: Between June 2017 to December 2020, sixty patients with a history of unsuccessful Extracorporeal shock wave lithotripsy (ESWL) and/or failed ureteroscopy for impacted ureteral calculi more than 15 mm who accepted TPLU were enrolled in our study. The patients' demographic information and post-treatment results were gathered and analyzed, retrospectively. Results: The patients' mean age was 46.25 ± 12.56 years. The mean size of the stone was 20.11 ± 4.76 mm. 37 (61.7%) patients had severe hydronephrosis (HDN) and 46 (76.7%) stones were radio-opaque. Almost all of the patients underwent TPLU by a single urologist. The mean operation time was 72.86 ± 6.07 minutes without intraoperative complication (only 3 stones had upward migration to the pyelocaliceal system). The main operative blood loss was 88.86 ml. The average length of stay in the hospital was 45.8 ± 8.11 hours. The stone free rate (SFR) at discharge was 57 (95%). The overall complication rate was 27 (45%). Regarding early complications, fever was found in 8 (13.3%) patients, and 3 patients (5%) had paralytic ileus. The rate of urine leak was 8.3%, and 8 (13.3%) patients required blood transfusions. In multivariate analysis, the multiple stones, bigger stone in size, incomplete SFR, longer duration of hospital admission, and severe HDN were associated with a high early complication rate (p = 0.05, 0.04, < 001, 0.03, and 0.01, respectively). Conclusions: TPLU is a harmless option for managing proximal ureteric stone as a primary procedure or salvage procedure with good outcomes and acceptable complication rates.
