Published: August 2020

Background Percutaneous drainage as the initial procedure for severe pancreatitis (SP) may not always be optimal. Our aim was to identify the characteristics of patients who failed percutaneous drainage and compare their outcomes with patients who underwent surgical intervention as the initial approach. Methods A retrospective review of a prospectively collected emergency general surgery registry of patients admitted to a tertiary-care, academic center with the diagnosis of SP who underwent an intervention was performed (2010-2018). Patients were divided into successful drainage (SD), drainage failure (DF), and surgery first (SF) groups. DF was defined as the need for surgical intervention. Results The study included 129 patients. Fifty (38.8%) patients underwent SF as their initial management modality. Among 79 patients who underwent drainage, 34 (43.0%) were in the DF group and progressed to surgical intervention. Within that group, 19 (55.9%) underwent open necrosectomy. The DF group was more likely to have lower rates of peripancreatic fluid collections, a higher rate of necrotizing pancreatitis, and a higher Acute Physiology and Chronic Health Evaluation (APACHE) II score when compared with the DS group. Mortality was higher in the DF and SF groups, and total length of stay and ICU length of stay were highest in the DF group. Discussion Patients who experience failure of drainage for SP have high morbidity and mortality rates and fare worse overall than patients who undergo surgery as the primary intervention. Patients with necrotizing pancreatitis and a higher APACHE II score might warrant surgical intervention over a drainage-first approach.

Published: August 2020

Background The management of flat epithelial atypia (FEA) on core needle biopsy remains controversial. The upstaging rates after surgical excision are variable. In this study, we seek to determine the upstaging rate of FEA at our institution. Methods Patients with a diagnosis of FEA were identified from the institution’s pathology database from 2009 to 2018. Patients were included in the study if FEA alone, without atypia or cancer, was identified on core needle biopsy. Patient demographics, imaging, management, and pathology characteristics were obtained. Statistical analysis performed using IBM SPSS 26.0 (Armonk, NY, USA). Results FEA was diagnosed on core needle biopsy in 235 patients from 2009 to December 2018. Forty-eight patients met the inclusion criteria. The majority of patients presented with calcifications on mammogram (n = 21, 64%) with the remainder as masses (n = 6, 18%) or architectural distortion (n = 6, 18%). Of those, 15 (31%) patients declined surgical excision, of which none developed cancer over a mean follow-up of 4.4 years. Of the 33 (69%) patients undergoing excisional biopsy, 17 (52%) confirmed FEA, 11 (33%) had benign findings, and 3 (9%) demonstrated atypical ductal hyperplasia on final pathology. One (3%) case revealed ductal carcinoma in situ (DCIS) and 1 (3%) was upgraded to invasive cancer for an overall upstaging rate of 4% (2/48). After a mean follow-up of 3.4 years, none of the excisional biopsy patients developed invasive breast cancer. Adjuvant therapy was used in the cases of DCIS and invasive cancer; however, chemoprevention with raloxifene or tamoxifen was not chosen by any of the remaining patients. Conclusion In our cohort, expectant management of FEA alone appears to be a safe option as our upstaging rate to DCIS or invasive cancer for FEA diagnosed on core biopsy was only 4%. Our study suggests that close follow-up is a safe and feasible option for pure FEA without a radiographic discordance found on core biopsy.

Background: Bipolar disorder is associated with a high risk of suicide. Routine neuroimaging examination exhibited that bipolar disorder with suicidality was associated with brain structural and functional changes. However, the alterations of brain dynamics have still remained elusive. Purpose: To investigate the alterations of brain dynamics in unmedicated bipolar disorder II depression with suicidality and predict the severity of suicidality. Materials and Methods: This prospective study included 106 bipolar disorder II participants (20 with suicidal attempt, 35 with suicidal ideation, 51 without suicidal ideation) and 50 healthy controls who underwent resting-state functional magnetic resonance imaging between February 2016 and December 2017. We first used sliding window analysis to evaluate the dynamic amplitude of low-frequency fluctuations. Then, we predicted the severity of suicidality using a multivariate regression model. Results: One-way analysis of covariance revealed that the dynamic amplitude of low-frequency fluctuations in the right temporal pole, inferior temporal gyrus, superior temporal gyrus and the bilateral precuneus/posterior cingulate cortex was significantly different among the four groups. Post hoc pairwise comparisons revealed that dynamic amplitude of low-frequency fluctuations was remarkably decreased in the bilateral precuneus/posterior cingulate cortex in the three bipolar disorder II groups compared with that in healthy controls group. Increased dynamic amplitude of low-frequency fluctuations was found in the right superior temporal gyrus and inferior temporal gyrus in the suicidal attempt group compared with that in the other groups, and in the right temporal pole in the suicidal attempt group compared with that in the suicidal ideation and healthy controls groups. Importantly, these temporal variabilities could be used to predict the severity of suicidality ( r = 0.330, p = 0.036), whereas static amplitude of low-frequency fluctuations couldn’t ( r = –0.050, p = 0.532). Conclusion: Our findings indicated that alterations of temporal variability in the precuneus/posterior cingulate cortex are such a common feature of bipolar disorder patients. Besides, the severity of suicidality could be predicted by the dynamic amplitude of low-frequency fluctuations abnormalities rather than static amplitude of low-frequency fluctuations abnormalities, which is the first evidence of dynamic brain alterations in bipolar disorder patients with suicidality. The proposed predictive model may be advantageous for clinical applications.

Published: August 2020

Purpose: The Hijra community is a cultural and gender grouping in South Asia broadly similar to western transgender communities, but with literature suggesting some differences in gender experience and patterns of psychosocial adversity. The present study aims to describe patterns of mental illness and psychoactive substance use in Hijra subjects and study their association with gender experience and psychosocial adversity. Methods: Fifty self-identified Hijras availing HIV-prevention services in New Delhi, India, were interviewed. Data on mental disorders, psychoactive substance use, quality of life, discrimination, empowerment, violence and gender identity were assessed using structured instruments. Results: Subjects were mostly in their mid-twenties, and had joined the Hijra community in their mid-teens. More subjects (46%) were involved in begging than in traditional Hijra roles (38%). Sex work was reported by 28% subjects. The rates of lifetime mental illness was 38%, most commonly alcohol abuse (26%); others had anxiety or depressive disorders (8% each), somatoform disorders (6%) and bulimia nervosa ( n = 1). Disempowerment was mostly experienced in domains of autonomy and community participation; 52% had experienced sexual or psychological violence. Discrimination was attributed to gender (100%), appearance (28%) or sexual orientation (28%). There were negative correlations between the physical domain of WHO-QOL and physical violence and depression scores; and between discrimination and WHO-QOL environmental, physical and psychological domains. Conclusions: This Hijra group showed high rates of mental disorder and substance involvement, related to QOL domains and experiences of discrimination and disempowerment.
Opinion on Immune Tolerance Therapeutic Development
Authors: Radi Zaher A. , Wynn Thomas A. 
Published: August 2020

Immune tolerance is defined by an active state of immune system unresponsiveness to foreign and self-antigens. Loss of immune tolerance to self-antigens and the resulting overexpression of autoantibodies can lead to tissue injury and development of various autoimmune diseases. In drug development, the goal of newly emerging immune tolerance therapies is to treat autoimmune disorders by restoring the immunoregulatory capacity of the immune system. Development of immune tolerance targets is initiated with the establishment of pharmacological efficacy in relevant disease animal models, followed by their stepwise translation to humans. This review discusses the major challenges to developing tolerance inducing pharmaceutical drugs, including the selection of appropriate disease models to establish efficacy, adequate, and acceptable in vitro and in vivo safety assessments, relevant biomarkers of human safety and efficacy, and finally, some regulatory guidelines to successfully develop immune tolerance therapeutics.

Quantifying and Categorizing ADRs in Psychiatric Residential Long-Stay Patients Utilizing UKU-SERS Scale
Authors: Mathew Joelin , Varghese Amruta , Sajith Manjusha 
Published: August 2020

Background: Psychotropic drugs are essential but not devoid of adverse drug reactions (ADRs), which lead to non-compliance and further failure of therapy, hampering the patient’s quality of life. Methods: A cross-sectional, observational study was carried out in a residential nursing home in Pune, India, from October 2018 to March 2019. Psychiatric inpatients of both genders and all ages receiving psychotropic drugs for at least one month were enrolled. Patients who were not alert or oriented enough to give a detailed history and response to a questionnaire, including dementia patients, and those who were not willing to give informed consent were excluded. The ADRs were categorized, and their management was documented using the Udvalg for Kliniske Unders gelser (UKU) side effect rating scale. ADRs were assessed for causality and severity using the WHO-Uppsala Monitoring Centre (WHO-UMC) causality assessment scale and the Modified Hartwig and Siegel scale. Results: In our study, 115 patients (76.6%) experienced 273 adverse drug events. Atypical antipsychotics accounted for the maximum number of ADRs (54.94%; n = 150). The most common ADRs were weight gain, constipation, and tremors. The majority of ADRs were “mild” and had a “possible” causality relationship. Conclusion: The study demonstrated a high incidence of ADRs, which was primarily managed either by reduction of dose or continued drug use with the treatment of side effects.

Background: Brief contact interventions such as telephone-based contacts appear to be useful in individuals who attempted suicide. Most studies of telephone-based contacts in such individuals typically consisted of frequent phone reminders for adherence to treatment and seeking help for mental health issues. Telephone-based psychosocial interventions that incorporate elements of supportive and problem-solving strategies are of interest in Indian settings due to their potential application in mitigating the wide mental health gap. Feasibility studies of telephone-based psychosocial interventions could help ascertain the difficulties that arise in the implementation of such treatments. Methods: A multicentric randomized controlled trial (RCT) is currently underway in general hospital settings in two Indian cities to study the efficacy of telephone-based psychosocial interventions in individuals with a recent suicide attempt, with routine telephone contacts (TCs) serving as the comparator. Prior to that RCT, this feasibility study was conducted to assess the acceptability of the telephone-based intervention and telephone contacts. Feasibility was assessed using dropout rates. Acceptability was assessed using participant-rated Likert-based visual analog scores from 0 to 10, with higher scores indicating greater acceptability. Results: Dropout rates and mean acceptability scores for telephone-based psychosocial interventions were 38.5% and 8.63, while those for TCs were 41.7% and 7.57, respectively. Conclusions: Telephone-based psychosocial interventions are feasible and acceptable in individuals with a recent suicide attempt.

Objective To evaluate the efficacy of the figure-of-eight (FOE) suture technique in the treatment of tunnel bleeding after femoral artery puncture compared with manual compression (MC). Methods This prospective, randomized, controlled study enrolled patients that had received transfemoral coronary artery angiography or percutaneous coronary intervention and then developed tunnel bleeding. They were randomly assigned into two groups: FOE suture group (ES group) and manual compression group (MC group). Total treatment time, performance frequency, performance time, rate of deep vein thrombosis (DVT) and in-hospital time after the procedure were compared. Results A total of 152 patients were enrolled in the study (ES group, n = 63; MC group, n = 89). Compared with the MC group, the total treatment time (mean ± SD: ES 22.3 ± 5.4 h versus MC 26.8 ± 6.8 h), performance frequency (mean ± SD: ES 2.1 ± 0.7 versus MC 2.6 ± 1.1), performance time (mean ± SD: ES 8.9 ± 2.5 min versus MC 12.3 ± 4.1 min), in-hospital time after the procedure (mean ± SD: ES 3.5 ± 1.2 days versus MC 4.8 ± 2.1 days) and DVT rate (ES 0.0% versus MC 6.7%) were significantly lower in the ES group. Conclusion The FOE suture technique effectively treated tunnel bleeding after femoral artery puncture.

Objective In recent years, a number of case–control studies have focused on the association between the DJ-1 g.168_185del polymorphism and the risk of Parkinson's disease (PD). However, the results have been conflicting. To estimate the relationship between the DJ-1 g.168_185del polymorphism and PD susceptibility, a comprehensive meta-analysis was performed. Methods Eligible studies concerning the DJ-1 g.168_185del polymorphism and PD susceptibility were searched for in the PubMed, Web of Science, Embase, Wanfang, CNKI, and VIP databases. Odds ratios and 95% confidence intervals were calculated to estimate the strength of the associations. In total, 11 studies were included in this meta-analysis, including 13 case–control studies with 2890 cases and 3043 controls. Results This meta-analysis revealed that DJ-1 g.168_185del variants are associated with PD susceptibility in the non-Asian population, but not in the Asian population. Conclusions Our meta-analysis suggests that DJ-1 gene variants are not associated with the risk of PD in the overall population.

Published: August 2020

Background Cerebral proliferative angiopathy is a vascular malformation associated with compromised blood-brain barrier and with migraine-like headache. Treating blood-brain barrier-compromised patients with erenumab, an anti-calcitonin gene-related peptide receptor monoclonal antibody, may be risky. Case We describe a case of a 22-year-old chronic migraine patient with cerebral proliferative angiopathy who presented to our hospital in status epilepticus 2 d after his first dose of erenumab. Serial magnetic resonance imaging (MRI) studies demonstrated progressive areas of diffusion restriction including the brain tissue adjacent to the cerebral proliferative angiopathy, bilateral white matter and hippocampi. His 6-month post-presentation magnetic resonance imaging was notable for white matter injury, encephalomalacia surrounding cerebral proliferative angiopathy and bilateral hippocampal sclerosis. He remains clinically affected with residual symptoms, including refractory epilepsy and cognitive deficits. Conclusion The evidence presented in this case supports further investigation into potential deleterious side effects of erenumab in patients with compromised blood-brain barrier, such as individuals with intracranial vascular malformations.
A Word of Caution for Future Studies in Patellofemoral Pain: A Systematic Review With Meta-analysis
Authors: Grant Camila , Fick Cameron N. , Welsh Judith , McConnell Jenny , Sheehan Frances T. 
Published: August 2020

Background: Patellar maltracking is widely accepted as an underlying mechanism of patellofemoral pain. However, methodological differences in the literature hinder our ability to generate a universal quantitative definition of pathological patellofemoral kinematics (patellar maltracking) in patellofemoral pain, leaving us unable to determine the cause of patellofemoral pain. Purpose: To systematically review the literature to provide evidence regarding the influence of confounding variables on patellofemoral kinematics. Study Design: Systematic review and random effects meta-analysis of control-case studies. Methods: A literature search of case-control studies that evaluated patellofemoral kinematics at or near full extension and were written in English was conducted using Embase, PubMed, Scopus, and Web of Science up to September 2019. Cases were defined as patients with patellofemoral pain. Studies were eliminated if they lacked quantitative findings; had a primary aim to assess therapy efficacy; or included participants with osteoarthritis and/or previous trauma, pathology, or surgery. A quality assessment checklist was employed to evaluate each study. Meta-analyses were conducted to determine the influence of confounding variables on measures of patellofemoral kinematics. Results: Forty studies met the selection criteria, with quality scores ranging from 13% to 81%. Patient characteristics, data acquisition, and measurement methods were the primary sources of methodological variability. Active quadriceps significantly increased lateral shift (standardized mean difference [SMD]shift = 0.33; P = .0102) and lateral tilt (SMDtilt = 0.43; P = .006) maltracking. Individuals with pain secondary to dislocation had greater effect sizes for lateral maltracking than had those with isolated patellofemoral pain (ΔSMDshift = 0.71, P = .0071; ΔSMDtilt = 1.38, P = .0055). Conclusion: This review exposed large methodological variability across the literature, which not only hinders the generalization of results, but ultimately mitigates our understanding of the underlying mechanism of patellofemoral pain. Although our meta-analyses support the diagnostic value of maltracking in patellofemoral pain, the numerous distinct methods for measuring maltracking and the limited control for cofounding variables across the literature prohibit defining a single quantitative profile. Compliance with specific standards for anatomic and outcome measures must be addressed by the scientific and clinical community to establish methodological uniformity in this field.

Published: August 2020

Background: There has been a shift toward functional nonoperative rehabilitation in the treatment of Achilles tendon rupture (ATR) despite a shortage of studies directly comparing nonoperative functional rehabilitation with traditional nonoperative immobilization. Purpose: To compare patient-reported outcome measures and functional outcomes for nonoperatively treated ATR with traditional cast immobilization or functional rehabilitation in a walking boot. Study Design: Randomized controlled clinical trial; Level of evidence, 2. Methods: In a single-center nonblinded study, 140 patients were randomized to compare treatment for acute ATR in (1) an immobilizing cast in reducing degrees of equinus over a 10-week period with 8 weeks of nonweightbearing mobilization or (2) a walking boot for 8 weeks with reducing equinus and immediate full weightbearing. Exclusion criteria were delayed presentation >2 weeks after injury, tendon reruptures, and latex allergy. Analysis was undertaken on an intention-to-treat basis. Results: A total of 69 patients (median age, 41 years [interquartile range, 33-50.5 years]) were randomized to walking boot treatment and 71 patients (41 [32-49]) to cast treatment. At 6 months, patients treated in a walking boot reported better Short Musculoskeletal Function Assessment (SMFA) dysfunction index (6.62 [2.21-12.50] vs 10.66 [4.96-13.42]; P = .050), SMFA bother index (7.29 [2.08-14.58] vs 10.42 [5.73-19.27]; P = .04), Achilles Tendon Total Rupture Score (71.5 [53.50-84.25] vs 54.0 [37-76]; P = .01), and Foot and Ankle Questionnaire core score (91 [81.89-97.55] vs 85 [78.25-92.09]; P = .04). At 1 year, there was no difference in SMFA dysfunction index (2.21 [0.74-5.88] vs 2.94 [1.47-6.62]; P = .25), SMFA bother index (2.08 [0-9.38] vs 5.21 [0.52-11.98]; P = .25), Achilles Tendon Total Rupture Score (92 [72.50-96] vs 87.5 [66.0-94.75]; P = .21), or Foot and Ankle Questionnaire core score (97.75 [89.46-99.00] vs 95.50 [90.88-97.50]; P = .18). Rerupture occurred in 5 and 11 patients ( P = .075) and venous thromboembolism in 2 and 3 patients ( P = .67) in the boot and cast groups, respectively. Fifteen patients in the boot group but none in the cast group had skin problems ( P < .001). Patients treated in a boot returned to driving at a median 12 weeks (vs 13 weeks for cast; P = .045), but there was no difference in time to return to work ( P = .48). Conclusion: Functional rehabilitation with early weightbearing is a safe alternative to traditional immobilizing treatment for ATR, giving better early functional outcomes, albeit with a higher incidence of transient minor skin complications.
