Purpose: Varicoceles can be a source of elevated seminal oxidative stress (OS) and sperm DNA fragmentation (SDF). However, it remains unclear whether varicocele repair (VR) could reduce these parameters. This systematic review and meta-analysis (SRMA) aims to investigate the impact of VR on SDF and seminal malondialdehyde (MDA). Materials and Methods: A literature search was performed in Scopus, PubMed, Ovid, Embase, and Cochrane databases. This SRMA included randomized controlled trials and observational studies reporting the pre- and postoperative levels of SDF and seminal OS in infertile men with clinical varicocele that underwent VR. Subgroup analyses included techniques of VR and SDF testing. The effect size was expressed as standardized mean difference (SMD). Results: Out of 1,632 abstracts assessed for eligibility, 29 studies with 1,491 infertile men were included. The analysis showed a significant reduction in SDF after VR, compared to preoperative values (SMD −1.125, 95% confidence interval [CI] −1.410, −0.840; p<0.0001) with high inter-study heterogeneity (I2=90.965%). Reduction in SDF was evident with microsurgical technique and non-microsurgical inguinal approaches (SMD −1.014, 95% CI −1.263, −0.765; p<0.0001, and SMD −1.495, 95% CI −2.116, −0.873; p<0.0001), respectively. Reduction in SDF was significant irrespective of testing was done by sperm chromatin dispersion (SMD −2.197, 95% CI −3.187, −1.207; p<0.0001), sperm chromatin structure assay (SMD −0.857, 95% CI −1.156, −0.559; p<0.0001) or TUNEL (SMD −1.599, 95% CI −2.478, −0.719; p<0.0001). A significant decrease in seminal MDA levels was observed following VR (SMD −2.450, 95% CI −3.903 to −0.997, p=0.001) with high inter-study heterogeneity (I2=93.7%). Conclusions Using pre- and post-intervention data, this SRMA indicates a significant reduction in SDF and seminal MDA levels in infertile men with clinical varicocele treated with VR. These findings may have important implications for the future management of this selected group of infertile patients.

Aims: The main objective of the present study was to study the diversity of endophytic fungi from Ruta graveolens, an important medicinal plant. The alkaloids produced by this plant have been used in many medical applications. The endophytic fungi that inhabit the plants are also recognized as rich sources of secondary metabolites. This study was aimed to isolate, identify and study the diversity of endophytic fungi in R. graveolens and to screen the isolates for their antimicrobial activities. Methodology and results : A total of 12 different fungal genera were isolated from R. graveolens collected from various sites in and around Bangalore. The species richness and colonizing frequency of endophytic fungi in this plant are comparatively less than other plants. This may be due to the secretion of the plant's phytochemicals, as it has antimicrobial activity and more than 120 phytochemicals in it. Screening of antimicrobial activity of all 10 isolates was done by agar well diffusion method, of which 80% of the fungal isolates could produce antimicrobials. Conclusion, significance and impact of study To conclude R. graveolens being a good medicinal plant along with its rich source of endophytes and their medicinal properties, can be exploited for the therapeutic applications.

Gastrointestinal mucormycosis is a rare disease with a significant mortality rate, even when promptly diagnosed and treated. An unusual complication was observed in India during the second wave of coronavirus disease 2019 (COVID-19). Two incidences of gastric mucormycosis were found. A 53-year-old male patient with a history of COVID-19 one month earlier came into the intensive care unit. After admission, the patient developed hematemesis, which was initially treated with blood transfusions and digital subtraction angiography embolization. Esophagogastroduodenoscopy (EGD) revealed a large ulcer with a clot in the stomach. During an exploratory laparotomy, the proximal stomach was necrotic. Histopathological examination confirmed mucormycosis. The patient was started on antifungals, but despite rigorous therapy, the patient died on the tenth postoperative day. Another patient, an 82-year-old male with a history of COVID-19, arrived with hematemesis two weeks earlier and was treated conservatively. EGD revealed a large white-based ulcer with abundant slough along the larger curvature of the body. Mucormycosis was verified by biopsy.He was treated with amphotericin B and isavuconazole. He was discharged after two weeks in a stable condition. Despite quick detection and aggressive treatment, the prognosis is poor. In the second case, prompt diagnosis and treatment saved the patient’s life.

Purpose: Despite the significant role of varicocele in the pathogenesis of male infertility, the impact of varicocele repair (VR) on conventional semen parameters remains controversial. Only a few systematic reviews and meta-analyses (SRMAs) have evaluated the impact of VR on sperm concentration, total motility, and progressive motility, mostly using a before-after analytic approach. No SRMA to date has evaluated the change in conventional semen parameters after VR compared to untreated controls. This study aimed to evaluate the effect of VR on conventional semen parameters in infertile patients with clinical varicocele compared to untreated controls. Materials and Methods: A literature search was performed using Scopus, PubMed, Embase, and Cochrane databases following the Population Intervention Comparison Outcome (PICOS) model (Population: infertile patients with clinical varicocele; Intervention: VR [any technique]; Comparison: infertile patients with clinical varicocele that were untreated; Outcome: sperm concentration, sperm total count, progressive sperm motility, total sperm motility, sperm morphology, and semen volume; Study type: randomized controlled trials and observational studies). Results: A total of 1,632 abstracts were initially assessed for eligibility. Sixteen studies were finally included with a total of 2,420 infertile men with clinical varicocele (1,424 patients treated with VR vs. 996 untreated controls). The analysis showed significantly improved post-operative semen parameters in patients compared to controls with regards to sperm concentration (standardized mean difference [SMD] 1.739; 95% CI 1.129 to 2.349; p<0.001; I2=97.6%), total sperm count (SMD 1.894; 95% CI 0.566 to 3.222; p<0.05; I2=97.8%), progressive sperm motility (SMD 3.301; 95% CI 2.164 to 4.437; p<0.01; I2=98.5%), total sperm motility (SMD 0.887; 95% CI 0.036 to 1.738; p=0.04; I2=97.3%) and normal sperm morphology (SMD 1.673; 95% CI 0.876 to 2.470; p<0.05; I2=98.5%). All the outcomes showed a high inter-study heterogeneity, but the sensitivity analysis showed that no study was sensitive enough to change these results. Publication bias was present only in the analysis of the sperm concentration and progressive motility. No significant difference was found for the semen volume (SMD 0.313; 95% CI -0.242 to 0.868; I2=89.7%). Conclusions This study provides a high level of evidence in favor of a positive effect of VR to improve conventional semen parameters in infertile men with clinical varicocele. To the best of our knowledge, this is the first SRMA to compare changes in conventional semen parameters after VR with changes in parameters of a control group over the same period. This is in contrast to other SRMAs which have compared semen parameters before and after VR, without reference to a control group. Our findings strengthen the available evidence and have a potential to upgrade professional societies’ practice recommendations favoring VR to improve conventional semen parameters in infertile men.

Herein, the synthesis of nanocomposites based on polymers, along with their classification as conductive hydrogels and bioscaffolds, is comprehensively discussed. Furthermore, their implementation in numerous tissue engineering and regenerative medicine applications is also described. The limitations of tissue engineering are also discussed here. The present review highlights and summarizes the latest progress in the tissue engineering domain directed at functionalized nanomaterials.

Traumatic orbital haemorrhage is an unfortunate complication with potential vision-threatening consequences.[1-3] The collection of blood can occur anywhere along the potential free orbital spaces,[4] but the subperiosteal collection of the blood is an important clinical variant where careful and timely intervention can give commendable rewards to the surgeon as well as to the patient.[1,2] Subperiosteal hematoma could be traumatic or non-traumatic, in turns, the non-traumatic cases may be due to bleeding tendency as in cases of leukaemia, blood dyscrasia and haemophilia or could be due to vascular malformation, venous congestion, infection, inflammation and neoplastic and non- neoplastic causes.[4] Here in this report, we elaborate the advantage of continuous ultrasound-guided needle drainage of the post-traumatic subperiosteal hematoma to enhance the clinical accuracy and to avoid the untoward complications.

OBJECTIVES: Open-source Electronic Health Record (EHR) systems have gained importance. The main aim of our research is to guide organizational choice by comparing the features, functionality, and user-facing system performance of the five most popular open-source EHR systems. METHODS: We performed qualitative content analysis with a directed approach on recently published literature (2012–2017) to develop an integrated set of criteria to compare the EHR systems. The functional criteria are an integration of the literature, meaningful use criteria, and the Institute of Medicine's functional requirements of EHR, whereas the user-facing system performance is based on the time required to perform basic tasks within the EHR system. RESULTS: Based on the Alexa web ranking and Google Trends, the five most popular EHR systems at the time of our study were OSHERA VistA, GNU Health, the Open Medical Record System (OpenMRS), Open Electronic Medical Record (OpenEMR), and OpenEHR. We also found the trends in popularity of the EHR systems and the locations where they were more popular than others. OpenEMR met all the 32 functional criteria, OSHERA VistA met 28, OpenMRS met 12 fully and 11 partially, OpenEHR-based EHR met 10 fully and 3 partially, and GNU Health met the least with only 10 criteria fully and 2 partially. CONCLUSIONS: Based on our functional criteria, OpenEMR is the most promising EHR system, closely followed by VistA. With regards to user-facing system performance, OpenMRS has superior performance in comparison to OpenEMR.

PURPOSE: The Z0011 trial showed that axillary lymph node dissection (ALND) can be safely avoided in breast cancer patients with low nodal burden (LNB). ALND can be performed in patients with high nodal burden (HNB). We aimed to determine whether HNB in early breast cancer patients can be predicted preoperatively to avoid sentinel lymph node biopsy (SLNB). METHODS: Early invasive breast cancer patients (cT1-2cN0) were retrospectively reviewed. We excluded patients with neoadjuvant chemotherapy and incomplete data. The patients were divided into the following groups based on surgical histology: no positive (N0), LNB, and HNB, defined as 0, 1–2, and ≥ 3 metastatic lymph nodes (LNs), respectively. Of the patients with metastatic nodal disease, only those with ALND were included in the analysis. Clinical, radiological, and histological parameters were evaluated using logistic regression analysis as predictors of HNB versus LNB and N0 combined. RESULTS: Of the 1,298 included patients, 832 (64.1%), 286 (22.0%), and 180 (13.9%) had N0, LNB, and HNB, respectively. Univariate logistic regression analysis revealed that sonographic features of breast tumor size (p < 0.0001), number of abnormal LNs (p < 0.0001), cortical thickness (p = 0.0002), effacement of the fatty hilum (p < 0.0001), and needle biopsy being performed (p < 0.0001) were indicators of HNB. Breast tumor grade (p = 0.0001) and human epidermal growth factor receptor 2 status (p = 0.0262) were also statistically significant. Among these significant features, multivariable stepwise logistic regression showed that the number of abnormal LNs is the sole independent predictor of HNB (p < 0.0001, area under the curve = 0.774). The positive predictive value of HNB in patients with ≥ 4 abnormal LNs was 92.9%. CONCLUSION: The detection of ≥ 4 abnormal LNs on ultrasound can help to identify HNB patients who require upfront ALND and thus avoid SLNB.
