Abstract
Background
Gastric cancer with portal vein tumor thrombus (PVTT) is poor prognosis, and the treatment remains challenging. Regarding surgery, there are only reports of highly invasive laparotomy. We report some techniques of the completely robotic total gastrectomy with thrombectomy and portal vein reconstruction for the patient with gastric cancer and PVTT for the first time.

Case presentation
A 79-year-old man was diagnosed with a 5-cm gastric cancer on the side of the lesser curvature from the middle of the gastric body to the cardia. Computed tomography revealed a massive PVTT extending from the left gastric vein to the portal trunk (28 x 16 mm). There were no other distant metastases. After 3 cycles of the chemotherapy, the PVTT shrank to 19 x 12 mm. After obtaining informed consent from the patient, robotic total gastrectomy with regional lymphadenectomy and thrombectomy were performed. We used the da Vinci Xi Surgical System. A 3-cm incision was made at the umbilicus, and a wound retractor was placed. Five additional ports were placed. The right side suprapancreatic lymph nodes were performed at the time of the thrombectomy. It was important to identify the precise extent of the PVTT with intraoperative ultrasonography before the thrombectomy. After PVTT identification, the portal trunk was clamped above and below the tumor thrombus with vascular clips. The membrane on the anterior wall of the portal trunk around the PVTT was carefully incised with da Vinci Scissors. The tumor thrombus was completely enucleated without separation. The incised part of the portal trunk was reconstructed with continuous 5-0 synthetic monofilament nonabsorbable polypropylene sutures. After removing the vascular clamps, we made sure there was no leakage from the portal vein and no tumor thrombus remnants with intraoperative ultrasonography. Robotic total gastrectomy with lymphadenectomy and Roux-en-Y reconstruction were performed. The patient was discharged without complications. The patient has remained alive for 30 months after surgery.

Conclusions
Robotic total gastrectomy with thrombectomy and portal vein reconstruction is a safe, minimally invasive, and precise surgery. It may contribute to improved prognosis of gastric cancer with PVTT when combined with chemotherapy.
Magnitude and determinants of male partner involvement in PMTCT service utilization of pregnant women attending public health facilities of Ethiopia, 2021: a systematic review and meta-analysis
Authors: Melis Tamirat , Fikadu Yohannes 
Published: February 2022

Abstract
Background
Infant antiretroviral prophylaxis has an important role in reduction of Human immune virus transmission from mother to child during the postpartum period. Male partner involvement was considered as a priority aforementioned area needs to be enhanced in Prevention of Mother-To Child Transmission (PMTCT). PMTCT service utilization can minimize the risk of the transmission of HIV from mother to child and related mortalities. Adequate utilization and adherence to this service has been challenging for some of the women if their partners are not aware or do partners do not support the women. The aim of this study is to assess the magnitude and determinants of male involvement in PMTCT service in Ethiopia.

Methods and materials
We had conducted an extensive search of literature as indicated in the guideline of reporting systematic review and meta-analysis (PRISMA). We had used PubMed, Google Scholar, and cross reference for searching articles. We had used the Joanna Briggs Institute (JBI) Meta-Analysis of Statistics Assessment and Review Instrument for critical appraisal of studies. Met-analysis and meta-regression were computed to present the pooled prevalence and determinants of male partner involvement with a 95% confidence interval using Revman.

Results
Among a total of 338 studies, 11 studies were included in this analysis. The estimated pooled magnitude of male partner involvement was 40% (95% CI: 29.11–50.69). Knowledge of husband on PMTCT (2.30, 95% CI 1.75, 3.02), perceived responsibility for the women (4.22, 95% CI 2.31, 7.71), being government employee (2.89, 95% CI 2.02, 4.12), cultural barriers (3.44, 95% CI 2.54, 4.65) and educational status of husband (2.4, 95% CI 1.79, 3.50) were the determinants of pooled estimates of male partner involvement in PMTCT activities.

Conclusion
The pooled prevalence of male partner involvement was lower than the study conducted in sub Saharan Africa. Knowledge of husband on PMTCT, perceived responsibility for women, occupational status, cultural barriers and educational status of husband were determinants of male partner involvement. Therefore, the existing strategies to improve male involvement should be strengthened.

Published: February 2022

AbstractBackgroundPeriprosthetic joint infection (PJI) is a devastating complication after total hip arthroplasty (THA) or total knee arthroplasty (TKA). It is scarce and contradicting evidence supporting the use of serum D-dimer to diagnose PJI in revision THA and TKA. This systematic review and meta-analysis aimed to investigate the accuracy of D-dimer in the diagnosis of periprosthetic infections.MethodsThe PubMed, Embase, Web of Science were systematically searched from the inception dates to August 15, 2020. We included all diagnostic studies of D-dimer in the diagnosis of periprosthetic infections. The literature's quality was evaluated by the QUADAS-2 tool, and Stata16 and Revman5.3 software carried out the meta-analysis.ResultsOf 115 citations identified by the search strategy, 10 studies (comprising 1756 participants) met the inclusion criteria.The literature quality assessment results show that most of the literature is low-risk bias literature. The combined sensitivity of D-dimer in diagnosing periprosthetic infections was 0.81 (95% confidence interval [CI] 0.71–0.88), combined specificity was 0.74 (95% CI 0.61–0.84), combined positive likelihood ratio was 3.1 (95% CI 2.0–5.0), combined negative likelihood ratio 0.26 (95% CI 0.16–0.41), combined diagnosis odds ratio 12 (95% CI 5–27), area under the Summary Receiver Operator Characteristic Curve (SROC) is 0.85 (95% CI 0.81–0.88). The data are statistically significant.ConclusionD-dimer has a high diagnostic value in diagnosing PJI and has clinical significance in diagnosing periprosthetic infection. In addition, there are relatively few studies on the threshold of D-dimer, different sampling types, different laboratory detection methods, and different races, so more prospective trials with large samples, multi-centers, and scientific design should be carried out in the future.
Deciphering mechanisms of immune escape to inform immunotherapeutic strategies in multiple myeloma

Published: February 2022

AbstractMultiple myeloma is an incurable cancer characterized by the uncontrolled growth of malignant plasma cells nurtured within a permissive bone marrow microenvironment. While patients mount numerous adaptive immune responses directed against their disease, emerging data demonstrate that tumor intrinsic and extrinsic mechanisms allow myeloma cells to subvert host immunosurveillance and resist current therapeutic strategies. Myeloma downregulates antigens recognized by cellular immunity and modulates the bone marrow microenvironment to promote uncontrolled tumor proliferation, apoptotic resistance, and further hamper anti-tumor immunity. Additional resistance often develops after an initial clinical response to small molecules, immune-targeting antibodies, immune checkpoint blockade or cellular immunotherapy. Profound quantitative and qualitative dysfunction of numerous immune effector cell types that confer anti-myeloma immunity further supports myelomagenesis, disease progression and the emergence of drug resistance. Identification of tumor intrinsic and extrinsic resistance mechanisms may direct the design of rationally-designed drug combinations that prevent or overcome drug resistance to improve patient survival. Here, we summarize various mechanisms of immune escape as a means to inform novel strategies that may restore and improve host anti-myeloma immunity.
Responding to foot health needs of people experiencing homelessness: the role of a publicly funded community‐based podiatry service

Published: February 2022

AbstractBackgroundPeople experiencing homelessness are known to suffer from poor health and can be reluctant to seek healthcare except in crisis. Foot and ankle problems are a concern; as well as causing discomfort and pain, they may escalate from a minor problem to a very serious one without timely and appropriate treatment. Little is known about the foot and ankle problems of people experiencing homelessness.This paper describes a podiatric service specifically for people experiencing homelessness, which includes a fixed site as well as outreach services. The service operates as part of the Homelessness Team program at Cohealth, a large community health service in Melbourne.MethodsThe study used routinely collected data. Every person who was seen by the podiatrist in the Cohealth Homelessness Team in 2019, whether on site or on outreach, was included in the study (n = 295). Of these, 156 were attending for the first time and 139 were returning clients. People who used the service were predominantly rough sleeping (45.2%), with 32.2% in unstable or insecure housing and 22.6% recently housed.ResultsSkin and nail pathologies (68.1%), inadequate footwear (51.9%) and biomechanical issues (44.1%) were the most common presentations. People sleeping rough were particularly likely to present with biomechanical issues (50.8%), acute wound care needs (17.4%) or traumatic injury (10.6%). Most people presented with more than one issue (mean = 2.4), and new clients (mean = 2.53) and those rough sleeping (mean = 2.69) had more issues than others.Outreach was the most effective way to reach clients in the most difficult circumstances (48.9% of those in unstable housing, 34.8% of rough sleepers). Most of the clients (81.4%) had connections with other services offered by Cohealth, such as social work or physiotherapy.ConclusionsThis study demonstrated that reaching and intervening on foot and ankle problems of people experiencing homelessness who may not seek care on their own could be achieved through a publicly funded health service, using simplified pathways to care including outreach. In addition to the long‐ and short‐ term benefits of the immediate podiatric treatment, building trust and connections through footcare may provide an entry point into accepting other health and welfare services.

Published: February 2022

AbstractBackgroundObstructive sleep apnea (OSA) is due to the obstruction of the upper airway during sleep. This condition is often associated with multiple symptoms and co-morbidities. There are many treatment options mentioned in the literature to manage OSA, among which interventional option of continuous positive airflow (CPAP) and non-interventional option, i.e., mandibular advancement device (MAD), which is an oral appliance (OA), are the most preferred ones. This study aims to evaluate the efficacy of customized maxillary oral appliances with mandibular advancement devices in moderate OSA patients.MethodsA prospective interventional study with a randomized controlled trial will be carried out involving 40 participants (sample size), with an apnea-hypopnea index (AHI) > 15–30, recorded on polysomnography (PSG). Study participants will be randomly divided into the following treatment groups: control group or group subjected to mandibular advancement device (MAD,n=20) and second group subjected to customized maxillary oral appliance (CMOA,n=20). Baseline assessment of apnea/hypopnea index (AHI), oxygen saturation in blood, percentage of rapid eye movement, electroencephalogram, electrocardiogram, oro-nasal airflow via a pressure transducer, and Epworth Sleepiness Scale will be done. Then both study group participants will receive their respective appliances. And after one month and three months of delivery of the appliance, all the parameters, i.e., AHI, oxygen saturation in blood, percentage of rapid eye movement, electroencephalogram, electrocardiogram, oro-nasal airflow via a pressure transducer, and Epworth Sleepiness Scale will be re-evaluated and compared with the baseline measurements. Descriptive and analytical statistics will be done. SPSS (Statistical Package for Social Sciences) Version 20.1 will be used as statistical software. The statistical significance between the two groups after one month and three months will be evaluated atp< 0.05.DiscussionWe expect, customized maxillary oral appliance to be more efficient in managing moderate OSA, in comparison with MAD. If the hypothesis of the present study is confirmed, then this customized maxillary appliance will be quoted as a “gold standard” for managing moderate OSA.Trial registrationCTRI/2020/07/026936Registered 31 July 2020.

Published: February 2022

Abstract
Background
Tendon-ligament injuries (TLIs), including Achilles tendinopathy, cruciate ligament injury, tennis elbow, rotator cuff injury, patellar tendinopathy, and tibial tendinopathy, are common musculoskeletal soft injuries during physical activity. Matrix metalloproteinase-3 (MMP-3) gene polymorphisms have been implicated in the etiology of TLIs in several genetic association studies with inconsistent results. The purpose of this study was to collect and synthesize the current evidences on the association of MMP-3 polymorphisms and TLIs.

Methods
The search was conducted using PubMed, Web of Science, EMBASE, Cochrane Library, CNKI and Wanfang databases, prior to July, 2021. Newcastle Ottawa Scale was used to appraise the study quality. Strengths of association were represented by odds ratios (ORs) and 95% confidence intervals (95% CIs).

Results
Thirteen studies with 2871 cases and 4497 controls met the eligibility criteria, and each study was in high quality. The overall analyzes suggested rs3025058 was associated with an increased TLIs risk (5A vs. 6A, OR = 1.20, 95% CI 1.03–1.40, P = 0.020). However, the association was not found for rs679620, rs591058, and rs650108 polymorphisms. Subgroup analysis by injury type suggested that rs679620 polymorphism was associated with a reduced risk to Achilles tendon rupture (AA + AG vs. GG, OR = 0.46, 95% CI 0.25–0.87, P = 0.020), and rs3025058 was associated with an elevated risk to anterior cruciate ligament injury (5A5A + 5A6A vs. 6A6A, OR = 1.46, 95% CI 1.03–2.06, P = 0.030). When stratified by ethnicity, the findings indicated that rs3025058 polymorphism was associated with an increased TLIs risk among Caucasians (5A6A vs. 6A6A, OR = 1.55, 95% CI 1.09–2.42, P = 0.020) and Brazilians (5A5A vs. 5A6A + 6A6A, OR = 2.80, 95% CI 1.44–5.45, P = 0.002).

Conclusion
Findings of this study suggest that rs679620 polymorphism is associated with a reduced Achilles tendon rupture risk, and rs3025058 polymorphism contributes to an increased TLIs risk in Caucasians and Brazilians. However, rs591058 and rs650108 polymorphisms do not show any association with TLIs.

Published: February 2022

Abstract
Objective
To describe the clinical profile of minimal invasive procedures performed in gynecology at the national referral hospital in Bhutan. A review of such procedures performed in gynecology was needed to assess the baseline information and generate our own experience. We conducted a descriptive study with a review of hospital records of minimal invasive procedures performed from 1st January to 31st December 2020 at the Department of Gynecology. Data were extracted into a structured pro forma. Descriptive statistics were used to express the results.

Results
The mean age of the patients was 33.9 ± 8.6 years of which the maximum was in the age group 25–34 years. 28 (17.5%) and 132 (82.5%) patients underwent emergency and elective procedures respectively. 142 (88.8%) and 18 (11.2%) patients underwent laparoscopic and hysteroscopic procedures respectively. Ovarian cystectomy was the most commonly performed procedure. The median operating time was 100 min (IQR 62.5–157.5). The overall complication rate was 2.5%. The median postoperative length of hospital stay was 24 h (IQR 3–24). Using our data and experience, we recommend a new health policy to recognize MIS in gynecology as a subspecialty and strengthen the existing service in gynecological MIS.
Quality control of compaction with lightweight deflectometer (LWD) device: a state-of-art
Authors: Duddu Sidhu Ramulu , Chennarapu Hariprasad 
Published: February 2022

AbstractThe infrastructure plays a vital role in stimulating economic growth. Any infra project requires proper planning, design, construction, quality control (QC), and quality assessment (QA). It is important to comply with QC and QA to avoid failure and enhance the long-term pavement performance in order to provide a safe and solid system of transportation. Researchers were replacing laborious and time-consuming density-based methods (sand cone and/or core cutter) with advanced stiffness or modulus-based NDT devices for the QC of compacted geomaterials. The lightweight deflectometer (LWD) is such a highly advanced and sophisticated device that was developed to evaluate the deformation modulus (ELWD) of compacted geomaterials as an alternative of density test. This device is portable, light-weight, user-friendly, and it is ideally suitable for all constructional geomaterials. This study is intended to provide a state-of-the-art on the LWD device as well as presented the ranges of deformation modulus for various geomaterials from several studies. For instance, in the case of soils, aggregates, and asphalt materials deformation modulus values were found to be in the range of 35–60 MPa, 80–120 MPa, and 120–170 MPa respectively. In addition, several studies have been compiled to completely comprehend the relationship between LWD and various devices.

Abstract
Background
Shrinking lung syndrome (SLS) is a rare manifestation of systemic lupus erythematosus (SLE) characterized by decreased lung volumes and diaphragmatic weakness in a dyspneic patient. Chest wall dysfunction secondary to pleuritis is the most commonly proposed cause. In this case report, we highlight a new potential mechanism of SLS in SLE, namely diaphragmatic weakness associated with myositis with CD20 positive B-cell aggregates.

Case presentation
A 51-year-old Caucasian woman was diagnosed with SLE and secondary Sjögren’s syndrome based on a history of pleuritis, constrictive pericarditis, polyarthritis, photosensitivity, alopecia, oral ulcers, xerophthalmia and xerostomia. Serologies were significant for positive antinuclear antibodies, anti-SSA, lupus anticoagulant and anti-cardiolopin. Blood work revealed a low C3 and C4, lymphopenia and thrombocytopenia. She was treated with with low-dose prednisone and remained in remission with oral hydroxychloroquine. Seven years later, she developed mild proximal muscle weakness and exertional dyspnea. Pulmonary function testing revealed a restrictive pattern with small lung volumes. Pulmonary imaging showed elevation of the right hemidiaphragm without evidence of interstitial lung disease. Diaphragmatic ultrasound was suggestive of profound diaphragmatic weakness and dysfunction. Based on these findings, a diagnosis of SLS was made. Her proximal muscle weakness was investigated, and creatine kinase (CK) levels were normal. Electromyography revealed fibrillation potentials in the biceps, iliopsoas, cervical and thoracic paraspinal muscles, and complex repetitive discharges in cervical paraspinal muscles. Biceps muscle biopsy revealed dense endomysial lymphocytic aggregates rich in CD20 positive B cells, perimysial fragmentation with plasma cell-rich perivascular infiltrates, diffuse sarcolemmal upregulation of class I MHC, perifascicular upregulation of class II MHC, and focal sarcolemmal deposition of C5b-9. Treatment with prednisone 15 mg/day and oral mycophenolate mofetil 2 g/day was initiated. Shortness of breath and proximal muscle weakness improved significantly.

Conclusion
Diaphragmatic weakness was the inaugural manifestation of myositis in this patient with SLE. The spectrum of myologic manifestations of myositis with prominent CD20 positive B-cell aggregates in SLE now includes normal CK levels and diaphragmatic involvement, in association with SLS.
A six-chambered heart: cor triatriatum sinister with double-chambered right ventricle in association with ventricular septal defect
Authors: Jaswal Vivek , Rana Pratyaksha , Bansal Vidur , Gourav Krishna Prasad , Sharma Arun , Thingnam Shyam Kumar Singh 
Published: February 2022

Abstract
Background
Cor triatriatum has been described as a heart with three atria in which the left atrium (cor triatriatum sinistrum) or right atrium (cor triatriatum dextrum) is divided into two compartments by a fold of tissue, a membrane, or a fibromuscular band. Double-chambered right ventricle, on the other hand, is identified by the presence of an anomalous muscle bundle dividing the right ventricle into two chambers.

Case presentation
Here, we describe the case of a child who had a combination of both of these rare entities, effectively creating a heart with six chambers. The child underwent a successful intracardiac repair.

Conclusions
The association of CTS with DCRV forming a “6-chambered heart” is extremely rare. Awareness of its existence and accurate preoperative diagnosis has important implications in its surgical repair with all the components of this disease spectrum, further increasing the complexity of a successful surgical repair.
