Abstract
Background
We explored the analgesic outcomes on postoperative day (POD) 1 in patients undergoing robot-assisted laparoscopic prostatectomy (RALP) who received intravenous patient-controlled analgesia (IV-PCA), rectus sheath bupivacaine block (RSB), or intrathecal morphine with bupivacaine block (ITMB).

Methods
This was a prospective, observational clinical trial. Patients were divided into three groups: IV-PCA (n = 30), RSB (n = 30), and ITMB (n = 30). Peak pain scores at rest and with coughing, cumulative IV-PCA drug consumption, the need for IV rescue opioids, and Quality of Recovery-15 (QoR-15) questionnaire scores collected on POD 1 were compared among the groups.

Results
The preoperative and intraoperative findings were comparable among the groups; the ITMB group required the least remifentanil of all groups. During POD 1, the ITMB group reported lower levels of pain at rest and with coughing, compared with the other two groups. During POD 1, incidences of severe pain at rest (10.0% vs. 23.3% vs. 40.0%) and with coughing (16.7% vs. 36.7% vs. 66.7%) were the lowest in the ITMB group compared with the RSB and IV-PCA groups, respectively. After adjustment for age, body mass index, diabetes mellitus, hypertension, and intraoperative remifentanil infusion, severe pain at rest was 0.167-fold less common in the ITMB group than in the IV-PCA group, while pain with coughing was 0.1-fold lower in the ITMB group and 0.306-fold lower in the RSB group, compared with the IV-PCA group. The ITMB group required lower cumulative IV-PCA drug infusions and less IV rescue opioids, while exhibiting a better QoR-15 global score, compared with the other two groups. Complications (nausea and pruritus) were significantly more common in the ITMB group than in the other two groups; however, we noted no ITMB- or RSB-related anesthetic complications (respiratory depression, post-dural headache, nerve injury, or puncture site hematoma or infection), and all patients were assessed as Clavien-Dindo grade I or II during the hospital stay.

Conclusion
Although ITMB induced complications of nausea and pruritus, this analgesic technique provided appropriate pain relief that enhanced patient perception related to early postoperative recovery.

Paraganglioma in the posterior mediastinum: a case report
Authors: Nam Jong-Ho , Park Jong-Seon , Choi Joon Hyuk 
Published: November 2020

Abstract
Background
Paragangliomas are tumors that arise from extra-adrenal chromaffin cells. Herein, we present a rare case of a functional paraganglioma in the posterior mediastinum.

Case presentation
A 36-year-old man presented with paroxysms of chest pain and headache. At presentation, the patient’s blood pressure was 190/120 mmHg. Chest computed tomography and magnetic resonance imaging revealed a left paravertebral mass in the posterior mediastinum. 123I-metaiodobenzylguanidine scanning revealed focally high tracer uptake in the left paravertebral area. The metanephrine level in the urine was elevated, confirming a rare, catecholamine-producing, functional paraganglioma in the posterior mediastinum. Before surgery, the patient was prepared by orally administering α- and β-adrenergic blockers. The mass was then resected via a lateral thoracotomy. The metanephrine level in urine was normal 24 h after surgery.

Conclusions
Paragangliomas in the posterior mediastinum are very rare, but more than half of all cases are functional. The associated symptoms are curable with complete resection, and long-term follow-up for recurrence is important.
Comparison of QT dispersion in patients with ST elevation acute myocardial infarction (STEMI) before and after treatment by streptokinase versus primary percutaneous coronary intervention (PCI)

Published: November 2020

Abstract
Background
QT dispersion (QTD) represents inhomogeneous ventricular repolarization such that an increased QTD may predispose the heart to malignant ventricular arrhythmias (VAs). This study was conducted to compare QTD in patients with ST-elevation myocardial infarction (STEMI) before and after treatment by streptokinase (SK) versus primary percutaneous coronary intervention (PCI).

Methods
The present case–control study was conducted on 185 STEMI patients who received SK (115 cases) or underwent primary PCI (70 cases). QTD and QT corrected dispersion before and 24 h after treatment. Likewise, they were also found to correct fatal arrhythmias (VT and VF) during the first 24 h after admission, and ejection fraction (EF) 24 h after treatment was evaluated.

Results
QTD decreased in the primary PCI group, though no significant difference was seen between the two studied groups (P > 0.05). A significant increase was detected in the EF mean values for the primary PCI-treated patients (P = 0.022). Moreover, there was a significant reduction in QTD of patients with fatal arrhythmias in the primary PCI group (P = 0.022).

Conclusion
An overall QTD reduction in the primary PCI group and a significant decrease in QTD of patients with fatal arrhythmias in the primary PCI group show that this treatment strategy is more efficient than thrombolytic therapy. As an important indicator of proper myocardial function, EF can independently predict improved myocardial function in the primary PCI group.
Right-sided infective endocarditis in association with a left-to-right shunt complicated by haemoptysis and acute renal failure: a case report
Authors: Hellwege Rubi Stephani , Gawaz Meinrad 
Published: November 2020

Abstract
Background
Infective endocarditis has a relevant clinical impact due to its high morbidity and mortality rates. Right-sided endocarditis has lower complication rates than left-sided endocarditis. Common complications are multiple septic pulmonary embolisms, haemoptysis, and acute renal failure. Risk factors associated with right-sided infective endocarditis are commonly related to intravenous drug abuse, central venous catheters, or infections due to implantable cardiac devices. However, patients with congenital ventricular septal defects might be at high risk of endocarditis and haemodynamic complications.

Case presentation
In the following, we present the case of a 23-year-old man without a previous intravenous drug history with tricuspid valve Staphylococcus aureus endocarditis complicated by acute renal failure and haemoptysis caused by multiple pulmonary emboli. In most cases, right-sided endocarditis is associated with several common risk factors, such as intravenous drug abuse, a central venous catheter, or infections due to implantable cardiac devices. In this case, we found a small perimembranous ventricular septal defect corresponding to a type 2 Gerbode defect. This finding raised the suspicion of a congenital ventricular septal defect complicated by a postendocarditis aneurysmal transformation.

Conclusions
Management of the complications of right-sided infective endocarditis requires a multidisciplinary approach. Echocardiographic approaches should include screening for ventricular septal defects in patients without common risk factors for tricuspid valve endocarditis. Patients with undiagnosed congenital ventricular septal defects are at high risk of infective endocarditis. Therefore, endocarditis prophylaxis after dental procedures and/or soft-tissue infections is highly recommended. An acquired ventricular septal defect is a very rare complication of infective endocarditis. Surgical management of small ventricular septal defects without haemodynamic significance is still controversial.

Abstract
Background
There are often specific endoscopic findings caused by deposition of lanthanum (La) in the gastric mucosa of patients taking lanthanum carbonate (LaC), a novel phosphate binder for patients on hemodialysis. We conducted a retrospective study to investigate the clinical significance of La deposition in the gastric mucosa, and the association between endoscopic features and histologic findings in the same population.

Methods
We compared background factors in patients taking LaC with and without La deposition in their gastroscopic biopsy specimen. We also investigated the relationship between gastric endoscopic biopsy specimens with La deposition and the concurrent endoscopic images.

Results
There was a significant difference in the total dose of LaC between the La-positive and La-negative groups (990 g [180–3150 g] vs. 480 g [225–1328 g]; p = 0.013). In 27 biopsy specimens with specific whitish mucosa, 10 showed mild histiocytic infiltration and 17 showed severe infiltration. In contrast, among 24 specimens with non-whitish mucosa, 5 showed no histiocytic infiltration, 10 showed mild infiltration, and 9 showed severe infiltration. There was a significant relationship between endoscopic features and the degree of histiocytic infiltration (p = 0.026).

Conclusions
We demonstrated that La deposition in the gastric mucosa depended on the total dose of LaC and was not affected by background factors. The specific endoscopic features of La deposition are associated with the infiltration of histiocytes, which represents the body’s normal response to foreign bodies.

Physical therapy interventions for older people with vertigo, dizziness and balance disorders addressing mobility and participation: a systematic review
Authors: Regauer Verena , Seckler Eva , Müller Martin , Bauer Petra 
Published: November 2020

Abstract
Background
Vertigo, dizziness and balance disorders (VDB) are among the most relevant contributors to the burden of disability among older adults living in the community and associated with immobility, limitations of activities of daily living and decreased participation. The aim of this study was to identify the quality of evidence of physical therapy interventions that address mobility and participation in older patients with VDB and to characterize the used primary and secondary outcomes.

Methods
A systematic search via MEDLINE (PubMed), Cochrane Library, CINAHL, PEDro, forward citation tracing and hand search was conducted initially in 11/2017 and updated in 7/2019. We included individual and cluster-randomized controlled trials and trials with quasi-experimental design, published between 2007 and 2017/2019 and including individuals ≥65 years with VDB. Physical therapy and related interventions were reviewed with no restrictions to outcome measurement. Screening of titles, abstracts and full texts, data extraction and critical appraisal was conducted by two independent researchers. The included studies were heterogeneous in terms of interventions and outcome measures. Therefore, a narrative synthesis was conducted.

Results
A total of 20 randomized and 2 non-randomized controlled trials with 1876 patients met the inclusion criteria. The included studies were heterogeneous in terms of complexity of interventions, outcome measures and methodological quality. Vestibular rehabilitation (VR) was examined in twelve studies, computer-assisted VR (CAVR) in five, Tai Chi as VR (TCVR) in three, canal repositioning manoeuvres (CRM) in one and manual therapy (MT) in one study. Mixed effects were found regarding body structure/function and activities/participation. Quality of life and/or falls were assessed, with no differences between groups. VR is with moderate quality of evidence superior to usual care to improve balance, mobility and symptoms.

Conclusion
To treat older individuals with VDB, VR in any variation and in addition to CRMs seems to be effective. High-quality randomized trials need to be conducted to inform clinical decision making.

Published: November 2020

Abstract
Background
World Health Organization estimated that 779 million people are at risk of getting schistosomiasis (SCH) and 240 million people were infected worldwide. SCH due to Schistosoma mansoni (S. mansoni) is a wide public health problem in Ethiopia. The aim of the survey was to quantify national and district disaggregated treatment coverage status for SCH and compare validated coverage with the one reported.

Methods
Community based cross-sectional survey was conducted in April 2019 among households with school age children (SAC) 5–14 years in seven purposively selected districts of the country. Segments to be surveyed were randomly selected and households to be interviewed from each segment were determined using systematic sampling technique. A total of 3378 households visited and 5679 SAC (5–14 years) were interviewed.

Results
Overall reported treatment coverage of Praziquantel (PZQ) against SCH was 4286 (75.5%). Males were 27% more likely to swallow the drug (AOR = 1.27; 95% CI: 1.09, 1.47) than females. SAC with age 10–14 years were 45% more likely to swallow the drug compared with their counter parts (5–9 years), (AOR =1.45; 95% CI: 1.25, 1.69). There is statistically significant association between PZQ swallowing status with school enrollment. (AOR = 20.90, 95% CI: 17.41, 25.08). Swallowing status of PZQ against SCH significantly higher for SAC treated in districts applied integrated treatment approach (87.5%) compared with SAC treated in vertical treatment approach (72.5%); P-value < 0.001. SACs were asked for reasons for not taking the drug and the main reported reason for not swallowing PZQ in the present study was none attending of the school.

Conclusions
Over all treatment coverage of PZQ against SCH in the present study was 75.5%. Although it is in accordance with WHO recommendation for Ethiopia, national programmatic improvements are necessary to achieve higher coverage in the future. To increase treatment coverage for PZQ against SCH in Ethiopia, school based training should target all schools. Moreover, mobilization, sensitization and implementation of the community wide treatment need to be improved.
The predicted impact of tuberculosis preventive therapy: the importance of disease progression assumptions
Authors: Sumner Tom , White Richard G. 
Published: November 2020

Abstract
Background
Following infection with Mycobacterium tuberculosis (M.tb), individuals may rapidly develop tuberculosis (TB) disease or enter a “latent” infection state with a low risk of progression to disease. Mathematical models use a variety of structures and parameterisations to represent this process. The effect of these different assumptions on the predicted impact of TB interventions has not been assessed.

Methods
We explored how the assumptions made about progression from infection to disease affect the predicted impact of TB preventive therapy. We compared the predictions using three commonly used model structures, and parameters derived from two different data sources.

Results
The predicted impact of preventive therapy depended on both the model structure and parameterisation. At a baseline annual TB incidence of 500/100,000, there was a greater than 2.5-fold difference in the predicted reduction in incidence due to preventive therapy (ranging from 6 to 16%), and the number needed to treat to avert one TB case varied between 67 and 157. The relative importance of structure and parameters depended on baseline TB incidence and assumptions about the efficacy of preventive therapy, with the choice of structure becoming more important at higher incidence.

Conclusions
The assumptions use to represent progression to disease in models are likely to influence the predicted impact of preventive therapy and other TB interventions. Modelling estimates of TB preventive therapy should consider routinely incorporating structural uncertainty, particularly in higher burden settings. Not doing so may lead to inaccurate and over confident conclusions, and sub-optimal evidence for decision making.

Authors: Sah Mukesh Kumar , Singh Abanish , Sangroula Raj Kumar 
Published: November 2020

Abstract
Background
COVID-19 is an emerging respiratory disease caused by a novel coronavirus. There is not much evidence assessing the knowledge of dental surgeons regarding COVID-19. This study was conducted to assess the knowledge of COVID-19 among dental surgeons of Nepal.

Methods
A web-based cross-sectional study was conducted among registered dental surgeons of Nepal. Ethical approval was obtained. Consent was taken, and knowledge on COVID-19 was assessed via a pre-tested structured questionnaire using Google form. The form was emailed to the participants. Descriptive analysis was performed using frequency, percentage, median and inter-quartile range. Man-Whitney test and Kruskal-Wallis tests were carried out to see the difference in knowledge score. P-value < 0.05 was considered statistically significant.

Results
Total 227 dental surgeons responded to the questionnaire (male: 46.4%; female: 53.7%). Almost two-third (65.2%) of the respondents were B.D.S. (Bachelor of Dental Surgery) graduates. Only 29.1% worked in the government hospitals. 17.6% were currently involved in COVID-19 management. Of the participants, 87.7% knew about the condition of the requirement of Personal Protective Equipment (PPE) but only 29.1% could correctly answer the framed question for PPE. The median knowledge score calculated was 14.0 (8.0–18.0). The bivariate analysis showed a statistically significant difference in knowledge score among the age group ≥30 years and < 30 years (p = 0.013); M.D.S. (Master of Dental Surgery) graduate and B.D.S. graduate (0.041); dental surgeons of government healthcare facilities and other healthcare facilities (p <  0.001); dental surgeons of COVID-19 centers and non-COVID-19 centers (0.002).

Conclusion
The dental surgeons of Nepal have a good knowledge of COVID-19, and they can be utilized for assisting in the management of COVID-19 cases in Nepal.

Abstract
Background
Genetic factors may influence the susceptibility to high-risk (hr) human papillomavirus (HPV) infection and persistence. We conducted the first genome-wide association study (GWAS) to identify variants associated with cervical hrHPV infection and persistence.

Methods
Participants were 517 Nigerian women evaluated at baseline and 6 months follow-up visits for HPV. HPV was characterized using SPF10/LiPA25. hrHPV infection was positive if at least one carcinogenic HPV genotype was detected in a sample provided at the baseline visit and persistent if at least one carcinogenic HPV genotype was detected in each of the samples provided at the baseline and follow-up visits. Genotyping was done using the Illumina Multi-Ethnic Genotyping Array (MEGA) and imputation was done using the African Genome Resources Haplotype Reference Panel. Association analysis was done for hrHPV infection (125 cases/392 controls) and for persistent hrHPV infection (51 cases/355 controls) under additive genetic models adjusted for age, HIV status and the first principal component (PC) of the genotypes.

Results
The mean (±SD) age of the study participants was 38 (±8) years, 48% were HIV negative, 24% were hrHPV positive and 10% had persistent hrHPV infections. No single variant reached genome-wide significance (p < 5 X 10− 8). The top three variants associated with hrHPV infections were intronic variants clustered in KLF12 (all OR: 7.06, p = 1.43 × 10− 6). The top variants associated with cervical hrHPV persistence were in DAP (OR: 6.86, p = 7.15 × 10− 8), NR5A2 (OR: 3.65, p = 2.03 × 10− 7) and MIR365–2 (OR: 7.71, p = 2.63 × 10− 7) gene regions.

Conclusions
This exploratory GWAS yielded suggestive candidate risk loci for cervical hrHPV infection and persistence. The identified loci have biological annotation and functional data supporting their role in hrHPV infection and persistence. Given our limited sample size, larger discovery and replication studies are warranted to further characterize the reported associations.
Mice lacking global Stap1 expression do not manifest hypercholesterolemia
Authors: Kanuri Babunageswararao , Fong Vincent , Haller April , Hui David Y. , Patel Shailendra B. 
Published: November 2020

Abstract
Background
Autosomal dominant familial hypercholesterolemia (ADH; MIM#143890) is one of the most common monogenic disorders characterized by elevated circulatory LDL cholesterol. Initial studies in humans with ADH identified a potential relationship with variants of the gene encoding signal transducing adaptor family member protein 1 (STAP1; MIM#604298). However, subsequent studies have been contradictory. In this study, mice lacking global Stap1 expression (Stap1−/−) were characterized under standard chow and a 42% kcal western diet (WD).

Methods
Mice were studied for changes in different metabolic parameters before and after a 16-week WD regime. Growth curves, body fats, circulatory lipids, parameters of glucose homeostasis, and liver architecture were studied for comparisons.

Results
Surprisingly, Stap1−/− mice fed the 16-week WD demonstrated no marked differences in any of the metabolic parameters compared to Stap1+/+ mice. Furthermore, hepatic architecture and cholesterol content in FPLC-isolated lipoprotein fractions also remained comparable to wild-type mice.

Conclusion
These results strongly suggest that STAP1 does not alter lipid levels, that a western diet did not exacerbate a lipid disorder in Stap1 deficient mice and support the contention that it is not causative for hyperlipidemia in ADH patients. These results support other published studies also questioning the role of this locus in human hypercholesterolemia.
