Prevalence and Diffusion of Gastrointestinal Parasite Infections in Swamp Water Buffalo (Bubalus Bubalis) Populations from Marshlands of Iraq

Background and objectives: New information on the epidemiology of gastrointestinal (GI) parasite infection in water buffaloes is crucial for understanding their risk factors and transmission. The objectives of this study were (1) to determine the prevalence of GI parasites in buffaloes in the Marshland areas of southern Iraq, and (2) to evaluate the association of risk factors with the parasitic infections.Materials and Methods: A total of 166 water buffaloes from the Marshland in the north of Basra (n=75), and Thi-Qar (n=91) provinces from November 2016 to April 2017 were enrolled. Fecal samples were collected and examined for the presence of helminth eggs and protozoal oocysts using sedimentation-flotation and centrifugal flotation techniques.Results: The overall prevalence of infection in buffaloes was 82% (136/166), with the highest number of single parasite infection (64%), followed by those with double (29%) and triple (7%) parasite infections. The most frequently identified parasites were Fasciola spp. (23%, 39/166), Eimeria spp. (19%, 32/166), Toxocara vitulorum (13%, 21/166), Trichostrongylus spp. (12%, 20/166), and Oesophagostomum spp. (10%, 10/166). Moniezia spp. was the only identified cestode with a prevalence of (8%, 13/166). A significant association was reported between feeding type and parasitic infections with Eimeria spp., Trichostrongylus spp., Moniezia spp., Trichuris spp., and Ostertagia ostertagia.Conclusion: The prevalence of GI parasitic infection in buffaloes raised in the Marshlands is high, indicating a high intensity of natural infection. The findings of this study imply an urgent need for the implementation of efficient control measures against parasitic infections in the Marshlands

Evaluation of Rezum therapy as a minimally invasive modality for management of Benign Prostatic Hyperplasia: A prospective observational study

Objective: To evaluate safety and efficacy of Rezum therapy as a minimally invasive modality for management of benign prostatic hyperplasia in patients with prostate volume 80cc. Methods: Between June 2020 and February 2023, A total of 98 patients diagnosed with BPH and managed by Rezum were included in this study. Patients were divided based on their prostate volume of either less than 80 cc or greater than 80 cc. We evaluated several parameters related to their condition, including prostate volume, post-voiding residual (PVR) before and after surgery, number of treatments received, maximum urine flow rate (Qmax) before and after surgery and mean follow- up periods. Results: The mean age was 68 years (SD 11.2). The median prostatic volume was 62 cc (IQR 41, 17). A maximum of 9 treatments were administered. Six months was determined to be the average post-operative follow-up period (IQR: 3.5-7.2). The mean preoperative total PSA was 2.7 (IQR 1, 2), preoperative mean PVR was 79.8 cm3, preoperative mean Qmax was 8.2 ml/s (IQR 4.7-10.5), and median post-operative days until catheter removal was four days (IQR 3,1). Post-operative PVR was 24.7 cm3 (IQR 18.2, 29.4) and the mean post-operative Qmax was 18.3 ml/s (SD 6.3). Qmax levels significantly increased, by an average of 8.2 ml/s (SD 7.13) (p < 0.001). Similarly, a decrease of average PVR of 97.28 cm3 (SD 95.85) (p < 0.001) was detected, which is a substantial reduction. Between prostates less 80cc and those over 80cc, there were no appreciable differences in Qmax or PVR (p-values: 0.435 and 0.431, respectively). Conclusions: From our study, we conclude that Rezum water vapor thermal therapy, as a minimally invasive modality, is an effective and safe surgical option for management of benign prostatic hyperplasia of men with moderate to severe lower urinary tract symptoms (LUTS). This procedure has been shown to be effective in patients with varying larger prostate volumes

Is quadratus lumborum block combined with low dose-spinal anesthesia an effective alternative to general anesthesia in patients undergoing percutaneous nephrolithotomy?

Background: General anesthesia in high-risk patients has many complications and needs long preoperative preparations and postoperative intensive care unit (ICU). Therefore the present study aimed to evaluate the efficacy of combined low-dose spinal anesthesia with quadratus lumborum block (QLB) as an alternative to general anesthesia for patients undergoing percutaneous nephrolithotomy. Patients and methods: A prospective study was conducted at the urology department of Al-Azhar University Hospitals in Cairo, Egypt, from January 2021 to January 2022. The study included 60 patients of ASA ll-lll scheduled for percutaneous nephrolithotomy. All patients received low-dose spinal anesthesia (5 mg bupivacaine) and QLB (QL1-QL2-QL3) approaches. The primary observation parameter was the efficacy of this technique as an alternative to general anesthesia. The secondary parameters measured were evaluation of need for intraoperative narcotics, postoperative pain score (VAS), and patients satisfaction as assessed using a 5-point Likert Scale. Results: None of the patients was given general anesthesia, and intraoperative sedation was given to nineteen patients (32.2%). No hemodynamic changes were observed in all patients. There was a significant correlation between the use of intraoperative sedation and stone site, intraoperative blood loss, and hospital stay. Pain intensity on VAS at rest and movement was low until the 24th postoperative hour. Patient satisfaction score was 3, 4, and 5 in 1 (1.7%), 4 (6.7%), and 55 (91.6%) patients, respectively. Conclusions: Combined low-dose spinal anesthesia with quadratus lumborum block is an effective alternative to general anesthesia in patients undergoing PCNL procedures with good postoperative analgesia. Patients with lower calyceal punctures have a lower incidence of intraoperative sedation requirements

Safety and efficacy of percutaneous nephrolithotripsy in comorbid patients: A 3 years prospective observational study

Purpose: To report the result of percutaneous nephrolithotripsy (PCNL) via standard nephrostomy tract in a single training institution. The perioperative complications in relation to the comorbid state are particularly assessed. Patients and methods: A prospective interventional study between January 2019 to November 2022, included 210 patients scheduled for PCNL. The average age was 40.3 ± 11.8 years (range 18- 67 years). Patients were categorized into two groups. The first group comprised 146 cases (69 .5%) with no associated co-morbidities while the second group 64 (30.5%) had co-morbidities such as obesity in 4 cases (1.9%), hypertension (HTN) in 24 cases (11.4%) cases, diabetes mellitus (DM) in 17 (8.1%) cases, history of recurrent stone surgery in 11 (5.2%) cases and more than one in 8 cases (3.8%). Co-morbidities, stone burden, location of stone, time of surgery, stay in the hospital, further operations, and negative events were among the reported data. Complications and the stone-free rate were the main outcome indicators. Results: Intraoperative complications were reported in 40 (18.8%) patients (18 group 1 and 22 group 2) during PCNL. Bleeding occurred in 22 (10.5%) patients (9 group 1 and 13 group 2), blood transfusions were needed in 4 (1.9%) (2 group 1 and 2 group 2), extravasation was observed in 11 patients (5.2%) (6 group 1 and 5 group 2) and cardiac arrhythmia in 3 (1.4%) (1 group 1 and 2 group 2) patients. Postoperative complications occurred in 61 patients (29%) (24 group 1 and 37 group 2) in the form of fever in 10 patients (4.8 %) (3 group 1 and 7 group 2) and prolonged leakage in 50 patients (23.8%) (21 group 1 and 29 group 2). One patient of group 2 died from postoperative sepsis. Extravasation and postoperative leakage were higher in diabetic patients than in non-diabetics. Stonefree rate was 60.5% (127 of 210). Clinically significant residual fragments (CSRFs) found in 70 cases (33.3%) (33 group 1 and 37 group 2). In 13 cases (6.2%) (5 group 1 and 8 group 2), clinically insignificant residual fragments (CIRFs) were found. In 8 (3 group 1 and 5 group 2) of the 13 cases, spontaneous stone passage was observed within 4-6 weeks of surgery. Residual stones in three cases (1 group 1 and 2 group 2) were asymptomatic and 4 mm or less, whereas stones increased in two cases of group 2. Among all factors studied, stone burden was significantly correlated to both intraoperative and postoperative complications. The occurrence of postoperative fever increased with large stone burden. Conclusions: PCNL is a therapeutic modality that is effective, feasible, and safe for a wide range of patients with concurrent medical issues. A steep curve is required to reduce intraoperative and postoperative complications

Twelve-month observational study of children with cancer in 41 countries during the COVID-19 pandemic

Introduction Childhood cancer is a leading cause of death. It is unclear whether the COVID-19 pandemic has impacted childhood cancer mortality. In this study, we aimed to establish all-cause mortality rates for childhood cancers during the COVID-19 pandemic and determine the factors associated with mortality. Methods Prospective cohort study in 109 institutions in 41 countries. Inclusion criteria: children &lt;18 years who were newly diagnosed with or undergoing active treatment for acute lymphoblastic leukaemia, non-Hodgkin's lymphoma, Hodgkin lymphoma, retinoblastoma, Wilms tumour, glioma, osteosarcoma, Ewing sarcoma, rhabdomyosarcoma, medulloblastoma and neuroblastoma. Of 2327 cases, 2118 patients were included in the study. The primary outcome measure was all-cause mortality at 30 days, 90 days and 12 months. Results All-cause mortality was 3.4% (n=71/2084) at 30-day follow-up, 5.7% (n=113/1969) at 90-day follow-up and 13.0% (n=206/1581) at 12-month follow-up. The median time from diagnosis to multidisciplinary team (MDT) plan was longest in low-income countries (7 days, IQR 3-11). Multivariable analysis revealed several factors associated with 12-month mortality, including low-income (OR 6.99 (95% CI 2.49 to 19.68); p&lt;0.001), lower middle income (OR 3.32 (95% CI 1.96 to 5.61); p&lt;0.001) and upper middle income (OR 3.49 (95% CI 2.02 to 6.03); p&lt;0.001) country status and chemotherapy (OR 0.55 (95% CI 0.36 to 0.86); p=0.008) and immunotherapy (OR 0.27 (95% CI 0.08 to 0.91); p=0.035) within 30 days from MDT plan. Multivariable analysis revealed laboratory-confirmed SARS-CoV-2 infection (OR 5.33 (95% CI 1.19 to 23.84); p=0.029) was associated with 30-day mortality. Conclusions Children with cancer are more likely to die within 30 days if infected with SARS-CoV-2. However, timely treatment reduced odds of death. This report provides crucial information to balance the benefits of providing anticancer therapy against the risks of SARS-CoV-2 infection in children with cancer

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

The effect of transplantation of adipose-derived stem cells to spinal cord on the recovery of urinary bladder function in patients having spinal cord injuries: a urodynamic study

Introduction Stem cells transplantation, as a therapeutic intervention for spinal cord injury (SCI), has been extensively studied by researchers in recent years. Our study aimed to study the effect of transplantation of adipose-derived stem cells into spinal cord by intrathecal injection on the recovery of urinary bladder function assessed by a urodynamics study in patients having SCIs. Patients and methods A total of 69 patients who had cervical incomplete tetraplegia were divided into two groups: group 1 had 37 patients who were treated with adipose-derived stem cells transplanted into spinal cord via intrathecal injection and were assessed by a urodynamic study before stem cell transplantation and then 6 months and 1 year after transplantation, and group 2 had 32 patients who underwent rehabilitation program only and were assessed by a urodynamic study before starting rehabilitation and then 6 months and 1 year after program. Results Eight (21.62%) patients benefitted from stem cells transplantation into spinal cord regarding urinary bladder function as assessed by urodynamics in varying degrees, but there was no significant difference between both groups. Conclusion Stem cells transplantation is a promising treatment for patients having SCI

Diuresis and inversion therapy to improve clearance of lower caliceal stones after shock wave lithotripsy: A prospective, randomized, controlled, clinical study

Objective: To improve the clearance of lower caliceal stones (LCSs) after shock wave lithotripsy (SWL) using a combination of intra-operative forced diuresis and inversion therapy. Materials and Methods: One hundred and fifty-seven consecutive patients with symptomatic, single LCSs of 5-20 mm size were prospectively randomized into two groups. The first (study group, SG) underwent SWL at the time of the maximum diuresis with the patient in the Trendelenburg position with an angle of 30 degree, while the second group (control group, CG) underwent standard SWL. After the last SWL session, patients were followed-up regularly using plain abdominal X-ray and renal ultrasound. The primary endpoint of the study was the stone-free rate (SFR) at 12 weeks. Results: A total of 141 patients completed the study treatment protocol and follow-up: 69 patients in SG and 72 patients in CG. Both groups were comparable in baseline data. SG showed significantly higher SFR at all follow-up time points. At week 12, 78.3% of SG were rendered stone free, whereas only 61.1% were stone free in CG (P = 0.030). Also, there was a significantly higher SFR for larger stones (>10 mm) and stones with higher attenuation value (>500 Hounsfield units) in SG than CG. Mild non-significant complications were reported in both groups. Conclusion: SWL with intraoperative forced diuresis and inversion seems to be an effective measure with minimal extra cost to improve LCS clearance post-SWL

Is scoring system of computed tomography based metric parameters can accurately predicts shock wave lithotripsy stone-free rates and aid in the development of treatment strategies?

Objective: The objective was to determine the predicting success of shock wave lithotripsy (SWL) using a combination of computed tomography based metric parameters to improve the treatment plan. Patients and Methods: Consecutive 180 patients with symptomatic upper urinary tract calculi 20 mm or less were enrolled in our study underwent extracorporeal SWL were divided into two main groups, according to the stone size, Group A (92 patients with stone ≤10 mm) and Group B (88 patients with stone >10 mm). Both groups were evaluated, according to the skin to stone distance (SSD) and Hounsfield units (≤500, 500–1000 and >1000 HU). Results: Both groups were comparable in baseline data and stone characteristics. About 92.3% of Group A rendered stone-free, whereas 77.2% were stone-free in Group B (P = 0.001). Furthermore, in both group SWL success rates was a significantly higher for stones with lower attenuation 830 HU (P 10 mm but total number SWL sessions and shock waves required for the larger stone group were higher than in the smaller group (P 830, SSD 90 mm and SSD >120 mm, respectively. On the other hand, SFR was 52.6% and 28.57% for stone >10 mm, mean HU >830, SSD 120 mm, respectively. Conclusion: Stone size, stone density (HU), and SSD is simple to calculate and can be reported by radiologists to applying combined score help to augment predictive power of SWL, reduce cost, and improving of treatment strategies
