Analysis of Factors Affecting Hematopoietic Stem Cell Mobilization Efficiency and Early Hematopoietic Reconstruction Indicators during Autologous Peripheral Blood Hematopoietic Stem Cell Transplantation.

Purpose To analyze the factors affecting the mobilization efficiency of hematopoietic stem cells and hematopoietic reconstruction indicators during autologous peripheral hematopoietic stem cell transplantation. Methods The clinical data of 54 patients who underwent autologous peripheral blood hematopoietic stem cell mobilization and transplantation at Xuzhou Central Hospital from May 2016 to April 2023 were retrospectively analyzed. The gender, age, disease type, mobilization regimen, number of chemotherapy sessions, G-CSF (granulocyte colony-stimulating factor) dosage, and platelet number at the time of collection were also collected. Moreover, the relationship between these indicators with mobilization results and hematopoietic reconstruction was analyzed. Results Results showed that age, disease type, and number of collections were significantly related to the mobilization results (number of CD34+ hematopoietic stem cells). Furthermore, multivariate analysis showed that the number of collections was an independent factor affecting mobilization efficiency. Similarly, age, platelet value at the time of collection, CD34+ stem cell value during collection, white blood cell count, and number of chemotherapy times were significantly related to the time of megakaryocytic hematopoietic reconstruction. Multifactor analysis found that age and platelet count were independent factors affecting the reconstruction time of the megakaryocytic system. However, no factor was related to the time of granulocyte hematopoietic reconstruction. Conclusion Platelet count and age when collecting hematopoietic stem cells are closely related to megakaryocytic hematopoietic reconstruction and are key indicators of early hematopoietic reconstruction after autologous hematopoietic stem cell transplantation.

Corrélation entre la réfraction et la longueur axiale du sujet Albinos

To investigate the relationship between refraction and ocular axial length in albinos. A cross-sectional, analytical study was carried out from June to November 2021 at the Central Hospital of Yaounde (Cameroon), which included consenting albino subjects aged over 15years. All subjects underwent visual acuity testing, axial length measurements and objective refraction under cycloplegia. We included 51 albino subjects. The mean age was 26.06±9.47years, and the sex ratio was 0.5. Type 2 oculocutaneous albinism (OCA2) was predominant, representing 82.4% of cases. The mean uncorrected visual acuity was 0.93±0.25 logMAR, and the most common ametropia was myopic astigmatism (52.9%). The mean axial length was 24.65±2.54mm with extremes of 21.54 and 30.33mm. Eyes with myopia and myopic astigmatism had significantly longer axial lengths than those with hyperopic and mixed astigmatism. A strong, significant negative correlation (r=-0.93; P˂0.001) between the spherical component of the refraction and axial length was found. The spherical component of the refraction decreases significantly with increasing axial length in albinos.

Shared decision-making support program for older patients with advanced cancer using a question prompt list and geriatric assessment: A pilot randomized controlled trial

IntroductionOlder patients with cancer are less likely to express their treatment preferences than younger patients. Question prompt lists (QPLs) facilitate communication between patients and physicians. Geriatric assessment (GA) is recommended when older patients with cancer make treatment decisions. This study estimated the effect size of a shared decision-making (SDM) support program combining QPLs with GA in terms of patients' subjective evaluation of the SDM process for a future definitive randomized controlled trial. We also evaluated the number and quality of aging-related communication during consultations, and feasibility and acceptability of the study for exploratory purposes. Materials and MethodsThis is a pilot study with randomized allocation and blind evaluation. Patients aged 65 years or older at the National Cancer Center Hospital, Tokyo, Japan, scheduled to discuss the changes of their treatment, were randomly assigned in a 1:1 ratio to the SDM support program or usual care. This program consisted of 30–60 min of face-to-face coaching, with QPLs and GA provided before the coaching. As the primary endpoint, the decisional conflict scores given by the patients immediately after the consultation were compared between the two groups. For the secondary endpoints, the number and quality of aging-related communications during the consultations were assessed by evaluators (blinded) using audio-recordings. Adherence, burden, and usefulness were assessed for evaluating feasibility and acceptability of the SDM support program. ResultsForty patients were enrolled. All patients completed the GA questionnaire, for which 70% did not require any individual assistance. Answering the questionnaires took approximately 11 min. The decisional conflict scores were mean [standard deviation (SD)]: 19.3 [10.8] vs. 18.0 [11.1] (effect size: Cohen's d = 0.12) for the SDM support program and usual care groups, respectively. The number of aging-related communications during the consultation for the new treatment was higher in the SDM support program group than the usual care (mean [SD]: 3.3 [1.2] vs. 2.2 [1.5], effect size: cohen's d = 1.32). Patients felt that the SDM support program was useful but not burdensome or difficult. DiscussionThe SDM support program was considered useful and feasible for older patients and able to facilitate communication regarding aging-related concerns. Trial registration numberThe study protocol was registered on September 23, 2020, in the UMIN Clinical Trials Registry (UMIN000041867).

Assessment of liposuction cannulas' interior: insights from visual inspection using a borescope

Introduction: Alterations in liposuction cannulas compromise their use and patient safety in healthcare services. Aim: to evaluate the interior of liposuction cannulas through visual inspection aided by a borescope. Design: this is a descriptive, quantitative study conducted at a materials and sterilization center of a public hospital in Minas Gerais, Brazil, from October 2023 to January 2024. Liposuction cannulas were randomly selected, chosen systematically. Visual inspection assisted by a borescope was conducted, and the data were recorded in a semi-structured instrument, analyzed using descriptive statistics. Results: Liposuction cannulas of sizes 3.0 mm and 4.0 mm were evaluated with equal frequency, as they are reusable devices without control regarding the number of sterilizations they have undergone since acquisition. The majority exhibited alterations detected through the borescope (66.7%), with notable occurrences of oxidation, stains, and/or discoloration (60.0%), residues or debris (33.3%), and grooves (25.0%). Implications: Tracking of liposuction cannulas identified alterations that compromise their usage, observed with the assistance of a borescope. The findings call for changes in current legislation within sterilization centers due to the absence of indication of this equipment as mandatory for aiding visual inspection.

Development and internal validation of a clinical prediction model for osteopenia in Chinese middle-aged and elderly men: a prospective cohort study

BackgroundEarly identification of patients at risk of osteopenia is an essential step in reducing the population at risk for fractures. We aimed to develop and validate a prediction model for osteopenia in Chinese middle-aged and elderly men that provides individualized risk estimates.MethodsIn this prospective cohort study, 1109 patients who attend regular physical examinations in the Second Medical Centre of Chinese PLA General Hospital were enrolled from 2015.03 to 2015.09. The baseline risk factors included dietary habits, exercise habits, medical histories and medication records. Osteopenia during follow-up were collected from Electronic Health Records (EHRs) and telephone interviews. Internal validation was conducted using bootstrapping to correct the optimism. The independent sample T-test analysis, Mann_Whitney U test, Chi-Square Test and multivariable Cox regression analysis were utilized to identify predictive factors for osteopenia in Chinese middle-aged and elderly men. A nomogram based on the seven variables was built for clinical use. Concordance index (C-index), receiver operating characteristic curve (ROC), decision curve analysis (DCA) and calibration curve were used to evaluate the efficiency of the nomogram.ResultsThe risk factors included in the prediction model were bone mineral density at left femoral neck (LNBMD), hemoglobin (Hb), serum albumin (ALB), postprandial blood glucose (PBG), fatty liver disease (FLD), smoking and tea consumption. The C-index for the risk nomogram was 0.773 in the prediction model, which presented good refinement. The AUC of the risk nomogram at different time points ranged from 0.785 to 0.817, exhibiting good predictive ability and performance. In addition, the DCA showed that the nomogram had a good clinical application value. The nomogram calibration curve indicated that the prediction model was consistent.ConclusionsOur study provides a novel nomogram and a web calculator that can effectively predict the 7-year incidence risk of osteopenia in Chinese middle-aged and elderly men. It is convenient for clinicians to prevent fragility fractures in the male population.

Characteristics of her2-positive breast cancer, and the current use of anti-her2 therapy and its related factors

ABSTRACT Objective: To describe the characteristics of patients with HER2-positive breast cancer and to identify the proportion of patients using anti-HER2 therapy, and treatment-making related factors. Methods: An analytical cross-sectional study was conducted on 79 patients with BC and HER2-positive diagnosed by immunohistochemistry (IHC) or with FISH at the Oncology Department of Hue University of Medicine and Pharmacy Hospital and Oncology Center of Hue Central Hospital from 1/2021 to 12/2022. Clinical and pathological features, type of drug, number of cycles using anti-Her2 therapy were recorded using medical documents. The decision-making related factors were recorded by questionnaire interviewing patients and relatives. Exclusion criteria included recurrent or previously treated tumors; having contraindications with anti-HER2 therapy; not being willing to participate in the study. SPSS 22.0 was used for the analysis. Results: Mean age was 54.14 ± 11.03. Patients with right-sided BC accounted for 53.1%. 60.8% of tumors were located in the upper right quadrant of the breast. Patient’s self-report of lumps was the most common cause of hospitalization (77.2%). By ultrasound, 60.2% of participants had a tumor size of 2 - 5cm. Abnormal lymph nodes were identified in 40.8% of patients. Histopathologically, invasive ductal carcinoma was found in the majority of tumors (75.9%). Stage II was predominant with 59.5% and 7.6% of patients with stage IV. The rate of treatment with Trastuzumab in our study was 27.8%. The main reason that patients refused anti-HER-2 therapy was financial problems (96.5%). The awareness of anti-HER2 therapy among patients and their relatives was significantly associated with the treatment decision (p = 0.007). Conclusion: Regarding the positive-HER2 BC patients, invasive ductal carcinoma was the major histopathological finding. More than half of the patients were classified as stage II of the disease. The rate of patients undergoing antiHER2 therapy was 27.8%. Financial problems were found to be the main reason for refusal of treatment. Awareness of anti-HER2 therapy is significantly associated with the patient’s decision on treatment.

Survey of patient satisfaction with genetic counseling services in Korea.

Since the 1990s, genetic clinics have been established in South Korea, enabling the provision of clinical genetics services. However, genetic counseling services are not widely used in the medical system. In contrast, recently, the demand for genetic counseling has increased due to the rapid development of genomic medicine. Therefore, it is important for medical geneticists and genetic counselors to collaboratively provide genetic counseling services. This study aimed to evaluate the perception and satisfaction of patients with rare genetic diseases and their families regarding genetic counseling services provided by a genetics team at the medical genetics center of a tertiary general hospital for rare genetic diseases. From April to November 2021, a survey was conducted with 203 individuals, including 111 and 92 individuals in the patient and family groups, respectively. Overall, 164 individuals (80.8%) responded that they were aware of genetic counseling services, and 135 individuals (66.5%) responded that they were aware of the role of genetic counselors. Patients and their families wanted to receive information about the following from genetic counseling: clinical manifestation and prognosis of the diagnosed disease (78.8%), treatment and management of the disease (60.6%), risk of recurrence within the family (55.7%), treatment options and alternatives for family and prenatal testing, and various support services. The score of satisfaction with genetic counseling services provided by the genetics team was 8.19 ± 1.68 out of 10. Patients with rare genetic diseases and their families were satisfied with genetic counseling services regarding their diseases, test results, and treatment options. Moreover, the patients could receive psychosocial support and referrals to other medical service providers and support services. As a genetic team approach, collaboration between medical geneticists and certified genetic counselors would be useful in providing information and in diagnosing, treating, and managing patients.

Early acute kidney injury in sepsis and septic shock

ABSTRACT Background: Acute kidney injury is one of the severe conditions in hospitalized patients. Acute kidney injury can develop early from admission, usually within the first 24 hours of ICU admission. In Vietnam, there have been limited studies monitoring the progression of acute kidney injury in the early stages. This study aims to investigate the incidence, severity, clinical, laboratory characteristics, and progression of acute kidney injury in patients with sepsis and septic shock within the first 48 hours. Methods: This study is a cross-sectional descriptive analysis of 101 patients who are 15 or older and have been diagnosed with severe infection and septic shock. These patients were treated in the Intensive Care Unit of Hue Central Hospital. The patient had treatment in accordance with a standardized protocol while being closely observed. Samples were collected for diagnostic testing, and the patient’s urine output and blood creatinine levels were diligently checked. Results: The prevalence of acute renal injury (AKI) was 60.40%, with stage 1 accounting for 50.82% of cases, stage 2 accounting for 22.95%, and stage 3 accounting for 26.23%. The cohort of individuals diagnosed with AKI exhibited an advanced age, with a mean age of 60.72 ± 17.41 years, and predominantly consisted of male subjects. Patients diagnosed with acute kidney injury showed a statistically significant decrease in urine output and an increased incidence of shock (p < 0.05). Additionally, these patients demonstrated lower levels of Hct, blood pH, and bicarbonate while exhibiting higher levels of blood urea, blood creatinine, AST, ALT, total bilirubin, PCT, and blood lactate (p < 0.05) compared to individuals without AKI. Patients with AKI had significantly elevated SOFA and APACHE II scores compared to individuals without AKI, as indicated by statistical analysis (p < 0.05). Upon admission, a significant proportion of patients, precisely 81.97%, experienced the development of AKI. Furthermore, a observation was made about the prompt recovery of these patients within the initial 24 and 48 hours following admission. Conclusion: The prevalence of AKI was accounted for 60.40%. Among the cases of AKI, stage 1 accounted for 50.82%, while stage 2 and stage 3 accounted for 22.95% and 26.23%, respectively. There were observed variations in urine output and rates of shock among individuals diagnosed with AKI. Additionally, SOFA and APACHE II scores were elevated. The percentage of AKI was 81.97% of patients upon their initial hospital admission, with a significant proportion seeing early recovery within the first 24 to 48 hours.

Does on-site computed tomography matter? A cross-sectional study of stroke patients' door-to-scan-time in rural hospitals.

Many rural Australian hospitals lack on-site computed tomography (CT). These hospitals often refer patients to local off-site private radiology clinics or to central hospitals, challenging the achievement of time-sensitive scans. For stroke patients, timely access to CT affects treatment options. This study questions whether on-site CT matters in rural hospitals by investigating stroke patients' door-to-scan-time (DTST) and CT scan sequence referrals. A retrospective chart audit was completed across four rural hospitals; two with on-site CT and two without. Adult emergency stroke presentations were randomly sampled. Comparisons between on-site and off-site CT hospitals were made for DTST and CT sequence referrals using Mann-Whitney U-tests and Fisher's exact tests. A total of 120 charts were audited (on-site CT, n = 60; off-site CT, n = 60). DTST was longer for off-site vs. on-site CT hospitals (median = 4.30 h vs. median = 0.70 h; U = 338, p < 0.001) regardless of whether presentations occurred in business hours or out of hours (p < 0.001). Off-site CT hospitals ordered less CT angiography or perfusion scanning (32% vs. 85%, p < 0.001). Off-site CT hospital patients had longer DTST and received less angiography or perfusion scanning. These findings suggest that on-site CT matters to rural stroke patients by improving equitable access to CT and appropriate scan referrals.

COVID-19 Associated Mucormycosis and Risk Factors: A Case-Control Study from Turkey

Background: Mucormycosis, a fatal fungal infection, has increased during the COVID-19 pandemic and posed significant challenges for clinicians. Objectives: Our research focused on identifying the clinical traits of patients with COVID-19-associated mucormycosis (CAM), comparing them with a control group, and identifying risk factors for the development of CAM. Methods: Our study was conducted on 39 CAM patients and 78 control patients from September 2020 to October 2022 at a tertiary education center and regional hospital. The control group was selected blindly in a 1:2 ratio among patients who did not develop mucormycosis, were hospitalized due to COVID-19, and were either discharged or deceased. The control group was matched to the case group regarding age and hospitalization date. To test potential risk factors for CAM, we performed a binary logistic regression analysis. The variables included in the multivariate binary logistic regression model were gender, diabetes, cumulative steroid dose (dexamethasone equivalent), duration of steroid treatment, and tocilizumab/anakinra treatment. Results: In our study, 39 patients were diagnosed with CAM. The average age of the patients was 66 ± 11.5 years. Of the patients, 54.7% (n = 64) were male, with a statistically significantly higher proportion of men in the CAM group (74.4% vs. 44.9%, P = 0.003). The diabetes rate was 51.3% (n = 60) among all patients, and it was higher in the CAM group (69.2% vs. 42.3%, P = 0.006). Regarding in-hospital mortality, the rate was higher in the CAM group (56.4% vs. 14.1%, P &lt; 0.001). The median length of stay in the hospital was 37 days for the CAM group and 10 days for the control group (P &lt; 0.001). The cumulative steroid dose was elevated in the CAM group compared to the control group (191 ± 61.4 mg vs. 117 ± 69.8 mg, P &lt; 0.001). The duration of steroid treatment was 16.5 ± 6.2 days in the CAM group, compared to 9.8 ± 4.7 days in the control group (P &lt; 0.001). Among CAM cases, paranasal involvement was the most common (56.4%), followed by rhino-orbital involvement (33.3%). In binary logistic regression analysis, male gender (OR, 3.9; 95% CI, 1.4 – 11.3), diabetes mellitus (OR, 4.4; 95% CI, 1.5 – 12.4), more than ten days of steroid use (OR, 5.5; 95% CI, 1.3 – 22.4), and tocilizumab/anakinra use (OR, 0.23; 95% CI, 0.06 – 0.8) were identified as risk factors for the development of CAM (p values 0.011, 0.005, 0.019, and 0.020, respectively). Conclusions: Male gender, diabetes mellitus, and steroid use for more than ten days were identified as positive risk factors, while tocilizumab/anakinra use was identified as a negative risk factor for the development of CAM.

Knowledge, attitudes, and practices towards urinary system stones among the Chengdu population

This cross-sectional study aimed to explore the knowledge, attitudes, and practices (KAP) regarding urinary system stones among the general public in Chengdu, China. Conducted between January and June 2023, this research targeted individuals undergoing physical examinations at the Health Management Center of Sichuan Provincial People's Hospital. Structured questionnaires were administered to collect demographic information and assess KAP related to urinary system stones. Following meticulous scrutiny, 1014 valid questionnaires were retained for analysis. The computed scores for knowledge, attitude, and practice were 9.36 ± 4.23 (possible score range 0–17), 37.75 ± 7.20 (possible score range 11–55), and 30.77 ± 4.00 (possible score range 10–50), respectively. These outcomes suggested insufficient knowledge and moderately positive attitudes and practices among the participants. Structural Equation Modeling (SEM) analysis revealed a direct impact of knowledge on attitude (β = 0.967, P < 0.001), with attitude subsequently exerting a direct influence on practice (β = 0.167, P < 0.001). This indicated an indirect impact of knowledge on practice. Additionally, there was a direct effect of knowledge on practice (β = 0.167, P < 0.001). In conclusion, the general populace in Chengdu exhibited insufficient knowledge and moderate attitudes and practices concerning urinary stones. These findings underscore the imperative for targeted educational interventions aimed at enhancing public awareness and fostering positive attitudes and practices toward urinary stone prevention and management.

Development and validation of a novel nomogram for predicting good neoangiogenesis after encephaloduroarteriosynangiosis in patients with moyamoya disease and type 2 diabetes mellitus: a case-control study.

Diabetes is often linked to poorer outcomes in patients with moyamoya disease (MMD). However, experience has shown that certain individuals with diabetes have favorable outcomes after encephaloduroarteriosynangiosis (EDAS). The authors aimed to develop a nomogram to predict good neoangiogenesis in patients with MMD and type 2 diabetes mellitus (T2DM) to aid neurosurgeons in the identification of suitable candidates for EDAS. Adults with MMD and T2DM who underwent EDAS between June 2004 and December 2018 were included in the analysis. In total, 126 patients (213 hemispheres) with MMD and T2DM from the Fifth Medical Centre of the Chinese PLA General Hospital were included and randomly divided into training (152 hemispheres) and internal validation (61 hemispheres) cohorts at a ratio of 7:3. Univariate logistic and least absolute shrinkage and selection operator regression analyses were used to identify the significant factors associated with good neoangiogenesis, which were used to develop a nomogram. The discrimination, calibration, and clinical utility were assessed. A total of 213 hemispheres in 126 patients were reviewed, including 152 (71.36%) hemispheres with good postoperative collateral formation and 61 (28.64%) with poor postoperative collateral formation. The authors selected 4 predictors (FGD5 rs11128722, VEGFA rs9472135, Suzuki stage, and internal carotid artery [ICA] moyamoya vessels) for nomogram development. The C-indices of the nomogram in the training and internal validation cohorts were 0.873 and 0.841, respectively. The nomogram exhibited a sensitivity of 84.5% and specificity of 81.0%. The positive and negative predictive values were 92.1% and 66.7%, respectively. The calibration curves indicated high predictive accuracy, and receiver operating characteristic curve analysis showed the superiority of the nomogram. The decision-making analysis validated the fitness and clinical application value of this nomogram. Then a web-based calculator to facilitate clinical application was generated. The nomogram developed in this study accurately predicted neoangiogenesis in patients with MMD and T2DM after EDAS and may assist neurosurgeons in identifying suitable candidates for indirect revascularization surgery.

Development and validation of a HPLC method simultaneously assisted with diode array and evaporative light scattering detection for the quantification of clinical mAb infusion bags in hospital pharmacy

To secure the supply chain of the monoclonal antibody (mAb) standardized infusion bags, a reversed phase (RP) HPLC analytical method assisted with a diode array detector (DAD) and an evaporative light scattering detector (ELSD) was implemented in the pharmacy department of the university hospital center of Besançon (UHCB). For a well-defined batch, the concordance between the two detections evaluated using the Lin’s concordance correlation coefficient (CCC) (Lin’s CCC = 0.9858) and a Bland–Altman plot was excellent. The analytical quantification of the different dose-banded (DB) of the infusion bags prepared in advance were achieved using this new reversed HPLC-DAD/ELSD analytical method in less than 4 min. For a same batch of mAbs, DAD generated nearly uniform response and showed a slightly superior accuracy than did ELSD. Their agreement in terms of calculated dose is excellent. In the event of a breakdown of one of the two detectors, this allowed the mAb infusion bags to continue to be monitored and thus improved the drug supply chain safety. As well our optimized method was able to monitor degradation mAbs created by accidental stress during the time period of stockage.

DEVELOPMENT OF A HUB–SPOKE NETWORK FOR TRANSCATHTER AORTIC VALVE IMPLANTATION: THE INTERVENTIONAL CARDIOLOGY UNIT OF IRCCS SAN RAFFAELE HOSPITAL (OSR HUB–SPOKE)

Abstract Background The growing prevalence of aortic stenosis determined in recent years an increase in candidates for percutaneous aortic valve replacement (TAVI), bringing out a difficult access to this procedure. In order to reduce waiting lists and to guarantee the training of the Interventional Cardiologists of Centers not equipped with on–site cardiac surgery, we implemented a TAVI protocol with one Hub center, the Interventional Cardiology Unit of IRCCS San Raffaele Scientific Institute, Milan, and two participating Spoke Centers: the ASST–Franciacorta Chiari Center and Valduce Hospital, Como.The aim of this study is to report in hospital outcomes of patients treated using this model of Hub–Spoke Network. Methods Patients included in this model were selected in the Spoke center where baseline clinical evaluation with echocardiography and CT scan were performed (inclusion and exclusion criteria attached). The cases were then discussed with a multidisciplinary team on–line and the procedure planned (access, valve type size). Once the procedure was scheduled, the patients underwent a single day transport to the Hub Center where they underwent TAVI and a same day return to the Spoke Center. A bailout hospitalization in the Hub Center was available in case of major complication. All Spoke Centers patients who underwent TAVI procedures in our Center according to our protocol were included in this analysis. The primary study objective was in hospital major adverse cardiac events (all cause or cardiovascular mortality, stroke, myocardial infarction); secondary study objectives were technical success, prolonged recovery in Hub Center and major vascular complications. Results Since 2019, a total of 69 patients underwent TAVI with the Hub and Spoke model. Mean age was 83 years ± 6 and mean ejection fraction was 59% ± 7%. Two patients (2.9%) had a prolonged hospitalization in the Hub center for a major vascular complication and an intra–procedural cardiac arrest, successfully resuscitated. Technical success was reached in 97.1% of patients. One patient experimented an ischemic stroke after the return in the spoke center: in hospital MACE was than 1.4%. Conclusion Considering the growing prevalence of aortic stenosis, The Hub Spoke Model for TAVI guarantees reduction in waiting lists, "access to care" for patients referred to Spoke centers, involvement and improvement of skills of their Interventional Cardiologists, keeping a high level of safety and efficacy.

Factors influencing implementation of simulation in nursing and midwifery training in Malawi

Background: The study explored factors influencing implementation of simulation-based education (SBE) in nursing and midwifery education in Malawi.Aim: This study aimed to identify factors influencing nursing and midwifery educators in selected training institutions and clinical sites.Setting: The study covered one district and four central hospitals, five professional training institutions, Ministry of Health and Nurses and Midwives Council of Malawi officials.Methods: Using mixed-methods approach, quantitative data were gathered from 293 participants, including 149 final-year nursing and midwifery students, and 144 clinical instructors. Qualitative data were obtained from 24 faculty members, 11 clinical instructors and two key informants. Researchers conducted 37 in-depth interviews, 10 focus group discussions and eight desk reviews. Descriptive statistics were used to analyse the quantitative data, while content analysis was used for qualitative findings.Results: Five themes emerged from qualitative data: absence of simulation in regulatory body syllabi, insufficient formal training, demand for knowledgeable clinical instructors, inadequate human and material resources, and resistance to change. Survey results indicated that 83% of the participants had theoretical SBE knowledge but lacked practical skills, with only 13% considering SBE as a current teaching method. Educators emphasised lack of infrastructure, skills laboratories, teaching hospitals, equipment, and a deficit in formal training as critical barriers to SBE implementation.Conclusion: The study concluded that skilled educators, appropriate infrastructure and resources could facilitate SBE implementation in Malawi.Contribution: Recommendations included regulatory body support, formal training for educators, utilisation of low-fidelity simulators, and establishment of SBE centres and corners in health facilities.

Three-Dimensional Laparoscopic Nephrectomy for Benign Nonfunctioning Kidneys: A Single-Center Initial Experience.

There are several types of benign renal diseases, such as urological stones, ureteropelvic junction obstruction, renal vascular disease, and inflammation, which are responsible for nonfunctioning kidneys. Laparoscopic nephrectomy (LN) is the gold standard for treating nonfunctioning kidneys with complications. This study presents the results of our initial experiences with 3D laparoscopic nephrectomy (3D-LN) for benign, nonfunctioning kidneys. From July 2021 to July 2023, 40 consecutive patients who underwent 3D transperitoneal laparoscopic nephrectomy were retrospectively evaluated at the Department of Urology and Department of General Surgery, Hue Central Hospital, Hue, Vietnam. Patient demographics, intraoperative and early postoperative results, postoperative recovery, complications, and three-month follow-up results were recorded. The mean age was 58.35 ± 14.9 years. There were 13 (32.5%) male and 27 (67.5%) female patients. Flank pain was the main reason for hospitalization in 33 cases (82.5%); the common cause of a nonfunctioning kidney was urological stones (62.5%). Twenty-three out of 40 patients underwent a left nephrectomy. The average operative time was 92.57 ± 28.69 minutes. A statistically significant difference in surgery time was found between the group with no adhesion and the group with mild adhesion, as well as between the first 19 patients and the last 18 patients (p <0.05). The mean blood loss was 51.62 ± 24.35 ml. Three cases were converted to open surgery due to severe adhesions. The postoperative complications rate was 8.1%. The average length of the postoperative hospital stay was 7.89 ± 3.59 days. Three-dimensional laparoscopic nephrectomy is a safe and effective method that increases depth perception and spatial orientation for surgeons and can compensate for the remaining shortcomings of traditional 2D systems.

Enhanced tuberculosis diagnosis with computer-aided chest X-ray and urine LAM in adults with HIV admitted to hospital (CASTLE study): A cluster randomised trial.

People with HIV (PHIV) admitted to hospital have high mortality, with tuberculosis (TB) being the major cause of death. Systematic use of new TB diagnostics could improve TB diagnosis and might improve outcomes. We conducted a cluster randomised trial among adult PHIV admitted to Zomba Central Hospital, Malawi. Admission-days were randomly assigned to: enhanced TB diagnostics using urine lipoarabinomannan (LAM) antigen tests (SILVAMP-LAM, Fujifilm, Japan and Determine-LAM, Alere/Abbot, USA), digital chest X-ray with computer aided diagnosis (dCXR-CAD, CAD4TBv6, Delft, Netherlands), plus usual care ("enhanced TB diagnostics"); or usual care alone ("usual care"). The primary outcome was TB treatment initiation during admission. Secondary outcomes were 56-day mortality, TB diagnosis within 24-hours, and undiagnosed TB at discharge, ascertained by culture of one admission sputum sample. Between 2 September 2020 and 15 February 2022, we recruited 419 people. Four people were excluded post-recruitment, leaving 415 adults recruited during 207 randomly assigned admission-days in modified intention-to-treat analysis. At admission, 90.8% (377/415) were taking antiretroviral therapy (ART) with median (IQR) CD4 cell count 240 cells/mm3. In the enhanced diagnostic arm, median CAD4TBv6 score was 60 (IQR: 51-71), 4.4% (9/207) had SILVAMP-LAM-positive and 14.4% (29/201) had Determine-LAM positive urine with three samples positive by both urine tests. TB treatment was initiated in 46/208 (22%) in enhanced TB diagnostics arm and 24/207 (12%) in usual care arm (risk ratio [RR] 1.92, 95% CI 1.20-3.08). There was no difference in mortality by 56 days (enhanced TB diagnosis: 54/208, 26%; usual care: 52/207, 25%; hazard ratio 1.05, 95% CI 0.72-1.53); TB treatment initiation within 24 hours (enhanced TB diagnosis: 8/207, 3.9%; usual care: 5/208, 2.4%; RR 1.61, 95% CI 0.53-4.71); or undiagnosed microbiological-confirmed TB at discharge (enhanced TB diagnosis, 0/207 (0.0%), usual care arm 2/208 (1.0%) (p = 0.50). Urine SILVAMP-LAM/Determine-LAM plus dCXR-CAD diagnostics identified more hospitalised PHIV with TB than usual care. The increase in TB treatment appeared mainly due to greater use of Determine-LAM, rather than SILVAMP-LAM or dCXR-CAD. Poor concordance between Determine-LAM and SILVAMP-LAM urine tests requires further investigation. Inpatient mortality for adults with HIV remains unacceptability high.
