Abstract
Background and objective A significant proportion of the adult population in the United States (US) live with some form of mental illness. The more prevalent conditions of depression and anxiety are typically managed in primary care settings rather than specialty care. The aim of this study was to determine the efficacy of a novel, measurement-driven psychiatric treatment platform delivered via an online telemental health platform as compared to treatment as usual (TAU). Methods The TAU dataset and the telemental health platform (Brightside) dataset were constructed based on the total populations of adult patients receiving care for depression from January 2018 through December 2020 (November 2018 through March 2021 for the Brightside group). Patients in both groups had a primary mental health diagnosis of depression and the presence of a positive screen for depression as measured by the Patient Health Questionnaire-9 (PHQ-9) upon initiation of treatment. HITLAB, an independent digital health verification and testing lab, conducted comparative analyses of the two groups using the Chi-square test of independence. Results Close to 80% of telemental health platform patients experienced a reduction of 5 or more points from their baseline PHQ-9 score as compared to 52% of TAU patients. The mean reduction in PHQ-9 score was slightly higher in the Brightside group (-11.5) versus the TAU group (-10.1). Chi-square tests of independence [x2 (1, n=6281) = 256.75, p≤0.001] for meaningful reduction and for remission [x2 (1, n=6281) = 105.50 p≤0.001] were highly significant. Conclusion The telemental health platform patients performed significantly better than those under psychiatric TAU in terms of reduction in symptoms of depression in adults.

Abstract
Abstract
Modified nucleosides are the core precursors for the synthesis of artificial nucleic acids, and are important in the field of synthetic and medicinal chemistry. In order to synthesize various triazolo-compounds, copper and ruthenium catalysed azide–alkyne 1,3-dipolar cycloaddition reactions also known as click reaction have emerged as a facile and efficient tool due to its simplicity and convenient conditions. Introduction of a triazole ring in nucleosides enhances their therapeutic value and various photophysical properties. This review primarily focuses on the plethora of synthetic methodologies being employed to synthesize sugar modified triazolyl nucleosides, their therapeutic importance and various other applications.

Abstract
Background: COVID-19 pandemic resulted in lockdown affecting all businesses globally. Everyone was forced to work from home (WFH) leading to challenges in productivity and motivation. Methodology: One thousand working professionals who worked from home participated in the online survey with semi-structured questionnaire using nonprobability Snowball sampling technique. Descriptive statistics was used to analyze the findings and to collect data method. Results: Participants were asked about their biggest worries during lockdown COVID-19 situation and their biggest worry was infection to COVID-19/death. Professionals were asked whether they were affected or not affected due to “WFH” in COVID situation. The questionnaire items were clubbed into six major categories of job role overload, lifestyle choices, family distraction, occupational discomfort, job performance, and distress, and majority categories were affected. Conclusion: Thus, it is observed that the increase in work commitments leads to distress among employees while distractions from family members disrupt the quality of work. While good job performance contributes to life satisfaction, distress significantly diminished it. This paves the way for more studies to be done on work–life balance under WFH arrangements for as long as the pandemic of COVID-19 is prevalent.

Abstract
BACKGROUND The cigarette smoking and its effect on the inflammatory cytokine levels in the smoker's saliva depicted the influence of electronic cigarettes on oral cytokine levels in oral fluids are scarce in the literature. OBJECTIVES The present trial was conducted to compare and determine the proinflammatory and anti-inflammatory cytokines in whole stimulated saliva samples of electronic cigarette smokers, conventional smokers, and participants with no smoke exposure. MATERIALS AND METHODS Sixty adult participants were divided into the following four groups of nonsmokers, current smokers, smokers smoking both conventional and e-cigarettes, and e-cigarette smokers. The saliva samples were assessed for Interleukins (IL-1B, 6, 8, 10, and IL-1RA), C-reactive protein (CRP), and tumor necrosis factor-alpha (TNF-α) using enzyme-linked immunosorbent assay. Plaque scores and Gingival Index, and body mass index were also calculated. RESULTS Statistically significant (P < 0.05) and remarkable relationship was seen in plaque scores and IL 1RA, 1 β, and 10 with the respective values as-0.285, 0.268, and 0.267. Regarding anti-inflammatory cytokines, CRP, IL-10, and IL-RA had the P-value of 0.073, 0.945, and 0.834 respectively. When these values were evaluated for proinflammatory cytokines, the P values were 0.0001, 0.019, 0.991, and 903 for TNF-α, IL-1 β, IL-6, and IL-8, respectively. These results were statistically significant for TNF-α (P = 0.001). CONCLUSION Within its limitations, the present study concludes that smoking e-cigarettes whether solely or in combination with conventional smoking increases the levels of proinflammatory cytokines such as TNF-α and IL-1 β with decreased counter IL-1RA levels.

Abstract
Abstract
Introduction/Objective
Biliary strictures are often considered malignant until proven otherwise. While the majority of malignant biliary strictures represent a primary neoplasm, secondary involvement by metastasis also rarely occurs. Primary cholangiocarcinoma and metastatic disease have different treatment considerations and likely different prognoses. The aim of this study is to look at the clinico-pathological characteristics of metastatic neoplasms of the bile duct.
Methods/Case Report
We retrospectively searched the pathology archives for biliary biopsies between 1991-2020. Patients with primary biliary, gallbladder, pancreatic, ampullary and hepatic malignancies and all cases of lymphoma were excluded from the study. A total of 20 cases were included.
Results (if a Case Study enter NA)
The median age of the patients was 63 years with a M:F ratio of 1.9:1. The biopsies were taken from the common bile duct (n=17), common hepatic duct (n=2) and left hepatic duct (n=1). 8 patients had synchronous and 12 had metachronous presentation. The overall median interval between the bile duct metastasis and primary was 18 months (Range: 0-100 months) for all patients and 33 months for metachronous cases. For 13 tumors, the primary site of origin was in the gastrointestinal tract (colon: 7; stomach: 4; anal canal: 1; gastro-esophageal junction: 1). Other primary sites included breast (3 cases), lung, endometrium and adrenal (1 each). One case presented with metastatic melanoma with an occult primary. Adenocarcinoma was the most common histological subtype seen in 17 cases. Other histological subtypes were squamous cell carcinoma, adrenocortical carcinoma and melanoma.
Conclusion
Secondary involvement of the bile duct by metastasis is rare. Most cases are metastasis from the lumenal gastrointestinal tract, with colon being the most common primary site. They are more likely to have a metachronous presentation with rare instances of bile duct metastasis as the first presentation. Awareness of secondary involvement of the biliary tree by metastasis is important as they can have prognostic and therapeutic significance.

Abstract
Abstract
Background
Implantable loop recorders (ILRs) have come to play an important role in the workup of patients with recurrent syncope of uncertain origin. In addition to detecting bradyarrhythmias related to syncope, which is the main diagnostic focus in these patients, ILRs are also capable of uncovering subclinical atrial fibrillation (AF).
Purpose
We sought to determine the percentage of patients monitored with an ILR for unexplained syncope who have AF detected and to describe clinical actions taken in these patients.
Methods
Patients enrolled in the Reveal LINQ Registry who received an ILR for unexplained syncope and had at least one follow-up form were included. The device automatically detects AF episodes lasting ≥2 minutes. Patients were considered to have AF based on an AF diagnosis made by the treating physician during follow-up or if device-detected AF was adjudicated as true AF by an external reviewer. AF detection rates were calculated using Kaplan-Meier methods.
Results
In total, 498 patients (aged 61.8±20.0 years, 49.6% female, CHA2DS2VASc score 2.2±1.7) were included and followed for 22±12 months. A history of AF was present in 97 (20%) patients, while 401 patients had no history. By 18 months, the incidence of AF was 70.9% (95% CI, 60.8%, 80.3%) in patients with a history of AF and 21.4% (95% CI, 17.4%, 26.1%) in patients without (Figure). AF detection in those with (30.4%) and without (30.1%) syncope during follow-up was similar. By the end of follow-up, and among patients with newly detected AF, 29/86 (33.7%) were on oral anticoagulation, 7 (8.1%) underwent AF ablation, 6 (7.0%) underwent other type of ablation, and 2 (2.3%) received cardioversion. Other actions among the whole cohort included implant of an IPG, ICD, or CRT in 98/498 (19.7%).
Conclusion
Among patients monitored with ILRs to determine the cause of recurrent syncope episodes, approximately 1 in 5 patients had new AF detected. In addition to improving the management of patients with syncope, ILR data served to support AF-related clinical decisions.

Abstract
BACKGROUND Common mental disorders (CMD) are among the largest contributors to global maternal morbidity and mortality. Although research on perinatal mental health in India has grown in recent years, important evidence gaps remain, especially regarding CMD. Our study aims to improve understanding of CMD among perinatal and non-perinatal women of reproductive age across two settings in India: Bangalore (Karnataka) and Tanda (Himachal Pradesh). METHODS The study is embedded within the Maternal and Perinatal Health Research Collaboration India (MaatHRI). This mixed-methods observational study comprises three consecutive phases: (i) focus group discussions and individual interviews to explore women's knowledge and seek feedback on CMD screening tools; (ii) validation of CMD screening tools; and (iii) prospective cohort study to identify CMD incidence, prevalence and risk factors among perinatal and non-perinatal women. Results of the three phases will be analyzed using inductive thematic analysis, psychometric analysis and multivariable regression analysis, respectively. CONCLUSION Improving understanding, detection and management of CMD among women is key to improving women's health and promoting gender equality. This study will provide evidence of CMD screening tools for perinatal and non-perinatal women in two diverse Indian settings, produce data on CMD prevalence, incidence and risk factors and enhance understanding of the specific contribution of the perinatal state to CMD.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) patients who have Clostridioides difficile infection (CDI) have worse outcomes. AIMS We aimed to determine whether such outcomes are the result of CDI or whether CDI occurs in patients who have more severe IBD. METHODS This was a retrospective study of patients hospitalized for ≥ 2 IBD flares from 2010 to 2019. The primary outcome was time to IBD flare between hospitalizations. First, time to flare was compared between patients who were hospitalized for a flare complicated by CDI and subsequently for a CDI-negative flare (cohort A, denoted +/-) versus patients who were hospitalized for two CDI-negative flares (cohort B, -/-). Second, time between flares was compared within the subset of cohort A patients who had three flares (cohort C, -/+/-) before and after CDI. RESULTS Time between flares was a median of 4 months (IQR 1-9) among 51 cohort A patients versus 12 months (IQR 6-38) among 51 cohort B patients (log-rank P < 0.01). In contrast, the median time between flares was similar within cohort C before and after CDI (log-rank P = 0.54). At time of the second IBD flare, patients in cohort A (+/-) were more likely to have moderate or severe disease compared to patients in cohort B (-/-). CONCLUSIONS Patients with prior CDI had shorter time to subsequent IBD flare relative to their CDI-negative counterparts. This is not likely due to CDI itself because there was no difference in time between flares before versus after acquiring CDI. Rather, patients who acquire CDI may have more severe IBD.

Abstract
Background: The use of membrane with the guided bone regeneration (GBR) has been a controversial aspect of the implant placement, which helps achieve the primary graft stabilization and inhibit early graft loss. Objectives: The present clinical trial was aimed to determine the results of GBR with nonresorbable (expanded polytetrafluoroethylene [e-PTFE]) and resorbable (collagen) membrane both clinically and radiographically for 2 years with dental implant placement. Materials and Methods: 16 subjects having 32 sites for implant placement in a split-mouth pattern were included in the study. The sites for implant was prepared and grafted with the autogenous graft procured from the mandibular ramus area followed by graft coverage with either e-PTFE or collagen membrane. Various radiographic and clinical parameters were assessed for 2 years at an interval of 6 months each. The collected data were recorded for each study subject for all the implant sites and were statistically analyzed. Results: The mean values for periodontal probing depth at 6 months, 12 months, 18 months, and 24 months were 2.25 ± 0.17, 2.67 ± 1.84, 2.64 ± 1.21, and 3.01 ± 0.52, respectively, for the e-PTFE group. For the collagen group, the probing depth mean values at 6 months, 12 months, 18 months, and 24 months were 2.30 ± 0.14, 2.59 ± 1.76, 2.62 ± 1.30, and 2.98 ± 0.81, respectively. The corresponding clinical and radiographic parameters at all time intervals were nonsignificant on the intergroup comparison. Conclusion: Dental implants placed with simultaneous GBR have an acceptable survival rate at the end of 2 years irrespective of the resorbable or non-resorbable membrane used.

Abstract
RadiaBeam has developed a 6 MeV accelerator that is compact and light enough to be placed on a robotic arm or light truck. The main drivers of size and weight in conventional accelerators are the power source and the shielding. Small dimensions are enabled by operation at 9.3 GHz frequency (X-band), which allows reducing the size and weight of all accelerator components. Thanks to the robust design of the accelerating structure, the accelerator can be used as a source for novel cargo inspection and radiotherapy techniques. In this paper, we present the linac design and its components, as well the results of the experimental demonstration of beam acceleration.

Abstract
Stress management is becoming very important part of cancer patient care. Chronic stressors lead to boost tumorigenesis and promote cancer development, recurrence, and drug resistant leading to poor health outcomes. The Hypothalamic-Pituitary-Adrenal (HPA) axis, which is activated by stress, also regulates Hypothalamic-Pituitary-Thyroid (HPT) axis. Stress related changes in immune function and inflammatory response also leads to reduced immune surveillance resulting in tumorigenesis. This article explores the hormonal axis impacted by stress and how chronic stress can lead to poor outcome of a cancer patient.

Abstract
SARS-CoV-2 enters host cells by binding angiotensin-converting enzyme 2 (ACE2). Through a genome-wide association study, we show that a rare variant (MAF = 0.3%, odds ratio 0.60, P=4.5×10-13) that down-regulates ACE2 expression reduces risk of COVID-19 disease, providing human genetics support for the hypothesis that ACE2 levels influence COVID-19 risk. Further, we show that common genetic variants define a risk score that predicts severe disease among COVID-19 cases.

Abstract
BACKGROUND Student psychological health has been an increasing concern. The COVID-19 pandemic situation has brought this vulnerable population into renewed focus. OBJECTIVE Our study aims to conduct a timely assessment of the effects of the COVID-19 pandemic on the mental health of college graduates and postgraduates. METHODOLOGY We conducted online survey with 550 students to understand the effects of the pandemic on their psychology and well-being. The data were analyzed through quantitative and qualitative methods. RESULTS Of the 550 students, 138 (71%) indicated increased stress and anxiety due to the COVID-19 outbreak. When asked about how the lockdown in COVID-19 situation affecting them, 97% said that it is severely affecting them. When asked about what the problems do you faced during online class, 5% said the Internet, 83.8% said noninteractive, and 11.2% said lack of explanatory mediums. When asked about number of hours spent on the Internet, 100% said more than 10 h. When asked about the activities to keep yourself busy during lockdown in COVID-19 situation, 37% said social media followed by 23% who mentioned cooking. CONCLUSION Due to the long-lasting pandemic situation and onerous measures such as lockdown and stay-at-home orders, the COVID-19 pandemic brings negative impacts on education. The findings of our study highlight the urgent need to develop interventions and preventive strategies to address the psychological health of college students.

The Colonic Mucosal MicroRNAs, MicroRNA-219a-5p, and MicroRNA-338-3p Are Downregulated in Irritable Bowel Syndrome and Are Associated With Barrier Function and MAPK Signaling. Gastroenterology 2021; 160:2409-2422.e19.

Abstract
BACKGROUND & AIMS Alterations in microRNA (miRNA) and in the intestinal barrier are putative risk factors for irritable bowel syndrome (IBS). We aimed to identify differentially expressed colonic mucosal miRNAs, their targets in IBS compared to healthy controls (HCs), and putative downstream pathways. METHODS Twenty-nine IBS patients (15 IBS with constipation [IBS-C], 14 IBS with diarrhea [IBS-D]), and 15 age-matched HCs underwent sigmoidoscopy with biopsies. A nCounter array was used to assess biopsy specimen-associated miRNA levels. A false discovery rate (FDR) < 10% was considered significant. Real-time polymerase chain reaction (PCR) was used to validate differentially expressed genes. To assess barrier function, trans-epithelial electrical resistance (TEER) and dextran flux assays were performed on Caco-2 intestinal epithelial cells that were transfected with miRNA-inhibitors or control inhibitors. Protein expression of barrier function associated genes was confirmed using western blots. RESULTS Four out of 247 miRNAs tested were differentially expressed in IBS compared to HCs (FDR < 10%). Real-time PCR validation suggested decreased levels of miR-219a-5p and miR-338-3p in IBS (P = .026 and P = .004), and IBS-C (P = .02 and P = .06) vs. HCs as the strongest associations. Inhibition of miR-219a-5p resulted in altered expression of proteasome/barrier function genes. Functionally, miR-219a-5p inhibition enhanced the permeability of intestinal epithelial cells as TEER was reduced (25-50%, P < .05) and dextran flux was increased (P < .01). Additionally, inhibition of miR-338-3p in cells caused alterations in the mitogen-activated protein kinase (MAPK) signaling pathway genes. CONCLUSION Two microRNAs that potentially affect permeability and visceral nociception were identified to be altered in IBS patients. MiR-219a-5p and miR-338-3p potentially alter barrier function and visceral hypersensitivity via neuronal and MAPK signaling and could be therapeutic targets in IBS.

Occurrence of exotic whitefly, Paraleyrodes minei Iaccarino (Hemiptera: Aleyrodidae) and other whitefly species on fruit crops in Maharashtra, India. 3 Biotech 2021; 11:264.

Abstract
Severe incidence of an exotic whitefly species Paraleyrodes minei Iaccarino (Homoptera: Aleyrodidae) was noticed in the Pune region of Maharashtra state, India, on the fruit trees guava (Psidium guajava L.), jamoon (Syzygium cumini L.), mango (Mangifera indica L.), chiku (Manilkara zapota L.), custard apple (Annona squamosa L.), citrus (Citrus spp.), banana (Musa spp.) and coconut (Cocos nucifera L.). Additional host plants of P. minei are neem (Azadirachta indica L.), Asoka (Saraca asoca (Roxb.) and temple tree (Plumeria alba L.). The identity of the pest was established based on sequences of the mitochondrial cytochrome oxidase 1 (mtCO-I) region amplified from genomic DNA of single whitefly. The incidence of P. minei was 100% on guava, jamoon, and custard apple; wherein under the surface of the infested leaves looks completely white with cottony wax. In the case of, coconut, guava, chiku, and banana, P. minei was co-colonising along with the rugose spiralling whitefly (Aleurodicus rugioperculatus Martin). Star gooseberry (Phyllanthus acidus L., new host record) plants were severely infested with less frequently collected whitefly, Bemisia bryniae (Singh). Pomegranate (Punica granatum L.) was infested by whitefly Siphoninus phillyreae (Haliday). The study highlights the need for continuous monitoring of invasive whitefly species population on important fruit crops for timely application of management practices to prevent losses of potential yield.

Abstract
The objective of this study was to describe the authors' long-term experience with the management of odontogenic keratocysts (OKCs). All OKC cases treated at the study centre between 1999 and 2015, with a minimum of 5 years of follow-up by December 2019, were reviewed retrospectively. Operative procedures including decompression/marsupialization, enucleation (E), E+Carnoy's solution (CS), E+CS+peripheral ostectomy (PO), and resection were assessed for complete resolution, partial resolution, and recurrence rates. In the parakeratinized non-syndromic group, E+CS+PO resulted in the lowest recurrence rate among the minimally invasive procedures (4.3%), while enucleation resulted in the highest rate (60%). Regarding the other modalities, recurrence was 12.5% for decompression, 11.5% for marsupialization, 16.7% for E+CS, 26.7% for E+PO, and 0% for resection. In the syndromic group, marsupialization resulted in a significantly higher recurrence (23.1%), while E+CS+PO cases showed no recurrence. No recurrence was observed in the orthokeratinized group patients treated with marsupialization or with E+CS. Based on clinico-radiographic features and observed results, it is concluded that OKC, although having a high recurrence rate, is a benign lesion and responds well to conservative procedures in most cases. Radical procedures should be reserved for unresponsive lesions and those with extensive tissue destruction.
