RESUMO
OBJECTIVE: We provide evidence-based recommendations regarding the treatment of interstitial lung disease (ILD) in adults with systemic autoimmune rheumatic diseases (SARDs). METHODS: We developed clinically relevant population, intervention, comparator, and outcomes questions. A systematic literature review was then performed, and the available evidence was rated using the Grading of Recommendations, Assessment, Development, and Evaluation methodology. A panel of clinicians and patients reached consensus on the direction and strength of the recommendations. RESULTS: Thirty-five recommendations were generated (including two strong recommendations) for first-line SARD-ILD treatment, treatment of SARD-ILD progression despite first-line ILD therapy, and treatment of rapidly progressive ILD. The strong recommendations were against using glucocorticoids in systemic sclerosis-ILD as a first-line ILD therapy and after ILD progression. Otherwise, glucocorticoids are conditionally recommended for first-line ILD treatment in all other SARDs. CONCLUSION: This clinical practice guideline presents the first recommendations endorsed by the American College of Rheumatology and American College of Chest Physicians for the treatment of ILD in people with SARDs.

OBJECTIVE: We provide evidence-based recommendations regarding screening for interstitial lung disease (ILD) and the monitoring for ILD progression in people with systemic autoimmune rheumatic diseases (SARDs), specifically rheumatoid arthritis, systemic sclerosis, idiopathic inflammatory myopathies, mixed connective tissue disease, and Sjögren disease. METHODS: We developed clinically relevant population, intervention, comparator, and outcomes questions related to screening and monitoring for ILD in patients with SARDs. A systematic literature review was performed, and the available evidence was rated using the Grading of Recommendations, Assessment, Development, and Evaluation methodology. A Voting Panel of interdisciplinary clinician experts and patients achieved consensus on the direction and strength of each recommendation. RESULTS: Fifteen recommendations were developed. For screening people with these SARDs at risk for ILD, we conditionally recommend pulmonary function tests (PFTs) and high-resolution computed tomography of the chest (HRCT chest); conditionally recommend against screening with 6-minute walk test distance (6MWD), chest radiography, ambulatory desaturation testing, or bronchoscopy; and strongly recommend against screening with surgical lung biopsy. We conditionally recommend monitoring ILD with PFTs, HRCT chest, and ambulatory desaturation testing and conditionally recommend against monitoring with 6MWD, chest radiography, or bronchoscopy. We provide guidance on ILD risk factors and suggestions on frequency of testing to evaluate for the development of ILD in people with SARDs. CONCLUSION: This clinical practice guideline presents the first recommendations endorsed by the American College of Rheumatology and American College of Chest Physicians for the screening and monitoring of ILD in people with SARDs.

Introduction: Alleviating pain and anxiety of patients during procedures is an essential skill for an Emergency Physician (EP). Several sedatives and dissociative agents are used for PSA (Procedural Sedation and Analgesia). In this study, we aimed to compare two drugs that is, ketamine and fentanyl for procedural sedation in adults with isolated limb injuries in the Emergency Department (ED). Materials and methods: In this prospective, randomised controlled interventional trial, patients aged between 18 to 65 years with isolated extremity injury requiring PSA in the ED were recruited. A total of 200 subjects were included in the study and randomly allocated to either the fentanyl (n=100) or the ketamine (n=100) group. Patients were blinded to the intervention and subsequently premedicated with Midazolam. Following this, they received either ketamine or fentanyl based on the group they were allocated to. Vital signs, including but not limited to the level of sedation, were measured at predetermined time intervals. A Modified Aldrete Score of >8 was used as a criterion for disposition from the ED. Data were collected in a pre-designed proforma. We aimed to compare the effectiveness as well as ascertain the safety profile of the two drugs for PSA in the ED. Results: There was no significant difference between the two groups when age, gender, mechanism of injury and comorbidities were compared. We found that there was no statistically significant difference between the two groups when blood pressure, respiratory rate and depth of sedation were compared. In both groups, there was a significant decrease in pain on the Numerical Rating Scale (NRS) following drug administration from 8 to 3 (p<0.001). Patients in the fentanyl group had an increased incidence of transient oxygen desaturation (p<0.001). Vomiting was more common in the ketamine group (p<0.001). Conclusion: PSA is a safe and efficacious procedure for patients undergoing painful procedures in ED. Patients in both the groups maintained hemodynamic stability throughout the procedure. From our study, we were able to conclude that both ketamine and fentanyl are similar in efficacy for PSA in the ED for adults with isolated limb injuries. In addition, no significant cardiovascular adverse events were noted in either group in our study.
RESUMO
PURPOSE: To assess whether Ultrasound guided dry needling is adequate for both common extensor tendon tears and tendinosis or whether ultrasound guided platelet rich plasma (PRP) has a superior outcome when compared to dry needling when there are tears of the common extensor tendon. MATERIALS AND METHODS: This is a single-centre, single-blinded, randomised controlled trial conducted between November 2018 and April 2020. 40 patients diagnosed with lateral epicondylitis based on clinical and sonographic features and having comparable baseline characteristics were randomly assigned to the two study groups (dry needling and PRP). Inclusion criteria were patients aged 20 years or more who were symptomatic for at least 3 months with sonographic evidence of lateral epicondylitis. Exclusion criteria were complete tear of common extensor tendon confirmed on ultrasound and presence of other associated diseases like osteoarthritis of shoulder and elbow. RESULTS: There was significant improvement in the visual analogue scale pain score in PRP group compared to the dry needling group at 9 months. However, this difference was not evident at 3 and 6 months follow-up. Mean improvement in common extensor tendon thickness in PRP group (5.1 mm at 3 months and 4.3 mm at 6 months) was slightly better than dry needling (4.4 mm at 3 months and 4.0 mm at 6 months). There was no difference in tear (if present) healing between both groups at 3 months. However at 6 months follow up, PRP demonstrated significant (mean-2.5) healing in tear compared to dry needling (mean-3.1). CONCLUSION: Two injections of Ultrasound guided PRP are more beneficial non operative treatment compared to ultrasound guided dry needling, in lateral epicondylitis.

BACKGROUND: Understanding relationships between HIV and multidrug-resistant TB (MDR-TB) is crucial for ensuring successful MDR-TB outcomes.METHODS: We used a cross-sectional analysis to evaluate sociodemographic and clinical characteristics as correlates of antiretroviral therapy (ART) use, having an HIV viral load (VL) result, and HIV viral suppression in a cross-sectional sample of people with HIV (PWH) and MDR-TB enrolled in a cluster-randomized trial of nurse case management to improve MDR-TB outcomes.RESULTS: Among 1,479 PWH, the mean age was 37.1 years; 809 (54.7%) were male, and 881 (59.6%) were taking ART. Housing location, employment status, and CD4 count differed significantly between those taking vs. those not taking ART. Among the 881 taking ART, 681 (77.3%) had available HIV VL results. Housing location, CD4 count, and prior history of TB differed significantly between those with and without a VL result. Among the 681 with a VL result, 418 (61.4%) were virally suppressed. Age, education level, CD4 count, TB history, housing location, and ART type differed significantly between those with and without viral suppression.CONCLUSION: PWH presenting for MDR-TB treatment with a history of TB, taking a protease inhibitor, or living in a township may risk poor MDR-TB outcomes.

A series of 1,1'-biphenyl-3-carboxamide and furan-phenyl-carboxamide analogs were synthesized using an optimized scheme and confirmed by 1H and 13C nuclear magnetic resonance and high-resolution mass spectrometry techniques. The synthesized peptidomimetics analogs were screened in vitro to understand the inhibitory potential of pancreatic lipase (PL). Analogs were assessed for the PL inhibitory activity based on interactions, geometric complementarity, and docking score. Among the synthesized analogs, 9, 29, and 24 were found to have the most potent PL inhibitory activity with IC50 values of 3.87, 4.95, and 5.34 µM, respectively, compared to that of the standard drug, that is, orlistat, which inhibits PL with an IC50 value of 0.99 µM. The most potent analog, 9, exhibited a competitive-type inhibition with an inhibition constant (Ki) of 2.72 µM. In silico molecular docking of analog 9 with the PL (PDB ID:1LPB) showed a docking score of -11.00 kcal/mol. Analog 9 formed crucial hydrogen bond interaction with Ser152, His263, π-cation interaction with Asp79, Arg256, and π-π stacking with Phe77, Tyr114 at the protein's active site. The molecular dynamic simulation confirmed that analog 9 forms stable interactions with PL at the end of 200 ns with root mean square deviation values of 2.5 and 6 Å. No toxicity was observed for analog 9 (concentration range of 1-20 µM) when tested by MTT assay in RAW 264.7 cells.

Background: Diarrhea in kidney transplant recipients (KTRs) can be associated with significant morbidity. Material and Methods: We evaluated 198 KTRs for a history of diarrhea post-kidney transplant at a tertiary care center in western India over 1 year. A protocol-based evaluation of diarrhea was done with respect to clinical features, diagnostic evaluation, associated acute allograft dysfunction, and its impact on long-term allograft function. Primary outcomes of interest were: chronic allograft injury (CAI) and the need for mycophenolate mofetil (MMF) withdrawal. We also assessed the effect of MMF withdrawal on the risk of the development of CAI. Results: Eighty-five of 198 (42.5%) recipients experienced diarrhea and a total of 140 diarrheal episodes were evaluated. The mean age of these 85 recipients was 38 ± 12 years and 72 (84.7%) were males. 73 of 85 recipients were on MMF at the time of diarrhea and in 35 (48%) of them MMF withdrawal was needed for chronic and persistent symptoms. Diarrhea was attributed to infective etiologies in 90 of 140 (64.2%) cases. Among the microbiologically confirmed infective diarrheal episodes, giardia and cryptosporidium were the common pathogens in 11/28 (39%) and 6/28 (21.4%) episodes respectively. One hundred and twenty-eight episodes out of 140 (91.4%) episodes were complicated by acute allograft dysfunction. Forty-one of 85 recipients (48.2%) developed chronic allograft injury and 12 (14.1%) developed allograft rejection (acute and/or chronic). Probability of chronic allograft injury was higher in those with MMF withdrawal. Conclusion: Diarrhea post-kidney transplant adversely affects graft function, especially after MMF withdrawal.

BACKGROUND: We conducted a nationwide cross-sectional study to estimate pretreatment drug resistance (PDR) prevalence in adults initiating ART in Sri Lanka following the WHO's recommendations. METHODS: HIV drug resistance was determined on dried blood spots (DBSs) using population-based sequencing of the protease and reverse transcriptase genes and interpretation was based on Stanford HIVdb v9.0. Analyses were weighted to adjust for multistage sampling and genotypic failure rate. We used logistic regression to assess differences between groups. RESULTS: Overall, in 10% (15 of 150) of patients initiating ART, HIV drug resistance mutations were detected. The prevalence of resistance to NNRTI drugs efavirenz/nevirapine was 8.4% (95% CI 4.6-15.0) but differed among those reporting having prior antiretroviral (ARV) exposure (24.4%, 95% CI 13.8-39.5) compared with 4.6% (95% CI 1.6-12.8) for those reporting as being ARV naive (OR 4.6, 95% CI 1.3-16.6, Pâ=â0.021). PDR to efavirenz/nevirapine was also nearly twice as high among women (14.1%, 95% CI 6.1-29.4) compared with men (7.0%, 95% CI 3.1-14.7) (Pâ=â0.340) and three times high among heterosexuals (10.4%, 95% CI 2.4-35.4) compared with MSM (3.8%, 95% CI 1.1-12.7) (Pâ=â0.028). NRTI PDR prevalence was 3.8% (95% CI 1.1-12.1) and no PI PDR was observed in the study. CONCLUSIONS: A high prevalence of efavirenz/nevirapine PDR was reported, especially in patients with prior ARV exposure, in women and those reporting being heterosexual. These findings highlight the need to fast-track the transition to the WHO-recommended dolutegravir-based first-line ART.

Crop yield varies considerably within agroecology depending on the genetic potential of crop cultivars and various edaphic and climatic variables. Understanding site-specific changes in crop yield and genotype × environment interaction are crucial and needs exceptional consideration in strategic breeding programs. Further, genotypic response to diverse agro-ecologies offers identification of strategic locations for evaluating traits of interest to strengthen and accelerate the national variety release program. In this study, multi-location field trial data have been used to investigate the impact of environmental conditions on crop phenological dynamics and their influence on the yield of mungbean in different agroecological regions of the Indian subcontinent. The present attempt is also intended to identify the strategic location(s) favoring higher yield and distinctiveness within mungbean genotypes. In the field trial, a total of 34 different mungbean genotypes were grown in 39 locations covering the north hill zone (n = 4), northeastern plain zone (n = 6), northwestern plain zone (n = 7), central zone (n = 11) and south zone (n = 11). The results revealed that the effect of the environment was prominent on both the phenological dynamics and productivity of the mungbean. Noticeable variations (expressed as coefficient of variation) were observed for the parameters of days to 50% flowering (13%), days to maturity (12%), reproductive period (21%), grain yield (33%), and 1000-grain weight (14%) across the environments. The genotype, environment, and genotype × environment accounted for 3.0, 54.2, and 29.7% of the total variation in mungbean yield, respectively (p < 0.001), suggesting an oversized significance of site-specific responses of the genotypes. Results demonstrated that a lower ambient temperature extended both flowering time and the crop period. Linear mixed model results revealed that the changes in phenological events (days to 50 % flowering, days to maturity, and reproductive period) with response to contrasting environments had no direct influence on crop yields (p > 0.05) for all the genotypes except PM 14-11. Results revealed that the south zone environment initiated early flowering and an extended reproductive period, thus sustaining yield with good seed size. While in low rainfall areas viz., Sriganganagar, New Delhi, Durgapura, and Sagar, the yield was comparatively low irrespective of genotypes. Correlation results and PCA indicated that rainfall during the crop season and relative humidity significantly and positively influenced grain yield. Hence, the present study suggests that the yield potential of mungbean is independent of crop phenological dynamics; rather, climatic variables like rainfall and relative humidity have considerable influence on yield. Further, HA-GGE biplot analysis identified Sagar, New Delhi, Sriganganagar, Durgapura, Warangal, Srinagar, Kanpur, and Mohanpur as the ideal testing environments, which demonstrated high efficiency in the selection of new genotypes with wider adaptability.
RESUMO
Dialysis patients have compromised bone health that increases their fracture risk due to low bone mass and deterioration in bone microarchitecture. Through meta-analyses of published studies, we conclude that dialysis patients suffer from impaired compartmental bone parameters compared with healthy controls. INTRODUCTION: We performed meta-analyses to determine the effect of chronic kidney disease (CKD) patients under dialysis on the trabecular and cortical parameters of radius and tibia. METHODS: This is a meta-analysis of cross-sectional and prospective clinical studies. PubMed, Web of Science, Google Scholar, and Scopus were searched using various permutation combinations. Dialysis patients were compared with non-CKD healthy controls using quantitative computed tomography. High-resolution peripheral quantitative computed tomography (HR-pQCT) and pQCT data of dialysis patients were dissected from eligible studies for pooled analysis of each parameter. RESULTS: Ten studies met the inclusion criteria that included data from 457 dialysis patients and 2134 controls. Pooled analysis showed a significant decrease (a) in total vBMD at distal radius [standard deviation of the mean (SDM) = -0.842, p = 0.000] and tibia (SMD = -0.705, p = 0.000) and (b) in cortical vBMD (SDM = -1.037, p = 0.000) at radius of dialysis patients compared with control. There were strong correlations between total vBMD and microarchitecture parameters at tibia in dialysis patients. CONCLUSIONS: At radius and tibia, bone mass, microarchitecture, and geometry at trabecular and cortical envelopes displayed impairments in dialysis patients compared with control. Tibial vBMD may have diagnostic value in dialysis. HR-pQCT and pQCT may be used to further understand the compartmental bones response to CKD-induced loss at different stages of CKD.

The management of pemphigus vulgaris (PV) is challenging. This study aimed to evaluate the immunomodulating effects of metformin on PV. The study was conducted in two phases: in the first phase, patients received routine first-line treatment (prednisolone plus azathioprine) for 2 months, then in the second phase, metformin was added to this regimen for another 2 months. After addition of metformin to the first-line medications, significant reductions were seen in serum IgG1 (reduced from 534.92 ± 134.83 mg/dL to 481.58 ± 130.46 mg/dL, P < 0.001), IgG4 (51.83 ± 27.26 mg/dL to 44.50 ± 26.05 mg/dL, P < 0.001) and interferon-γ (277.99 ± 108.71 pg/mL to 45.05 ± 17.080 pg/mL, P = 0.03) concentrations. The suppressant effect of metformin was greatest on IgG4 (coefficient of variation 1.28), the dominant subclass of IgG involved in PV. Metformin could have immunomodulating effects on PV with controlling effects on steroid complications.

CASE SUMMARY: We present the case of a 50 year old male patient being treated for chronic myeloid leukemia by the tyrosine kinase inhibitor, Ponatinib. After 3 months of treatment, he developed a sight-threatening granulomatous panuveitis in both eyes, with choroidal effusions and neurosensory retinal detachments. Except for a positive interferon-gamma release assay suggesting previous Tuberculosis exposure, all uveitis investigations were normal. Discontinuation of the suspected causative drug led to resolution of signs and a consequent improvement in visual acuity. CONCLUSION: Ponatinib use may be associated with with a uveitic phenotype that is reminiscent of Harada's disease. We compare and contrast this rare ocular phenomenon with Vogt-Koyanagi-Harada syndrome and discuss a possible immunological basis.

AIMS: Due to the lack of high-quality evidence and consensus on adjuvant treatment for locoregionally advanced penile cancer, we reviewed the outcomes of pN3 patients to determine the suitable adjuvant treatment options. PATIENTS AND METHODS: All consecutive pN3 penile cancer patients treated at our institution between January 2010 and December 2018 were reviewed to assess the impact of demographical, pathological and treatment factors on disease-free survival (DFS) and overall survival. The DFS and overall survival were estimated using the Kaplan-Meier method and association was tested using the Cox regression model (two-sided test with P < 0.05 considered significant). RESULTS: Of 128 patients, 31 (24%) had pelvic nodal involvement. Twenty-six patients (20.3%) received no adjuvant treatment, 40 (31.3%) received single modality adjuvant treatment and 62 (48.4%) received multimodality adjuvant treatment (a combination of chemotherapy and radiotherapy). At a median follow-up of 22 months, the DFS and overall survival were 55.4 and 62%, respectively. The best DFS and overall survival was noted with chemotherapy followed by concurrent chemoradiation (C-CTRT; 93% each). On multivariate analysis, both DFS and overall survival were worse with pelvic node involvement (2.2 [1.3-4], P = 0.027 and 2.2 [1.3-4], P = 0.027, respectively) and better with any adjuvant treatment (single modality: 3 [1.5-5.5], P < 0.001; multimodality: 3.1 [1.6-6], P < 0.001). C-CTRT was associated with improved DFS over chemotherapy alone (0.17 [0.4-0.78], P = 0.02) but not over radiotherapy alone (0.35 [0.07-1.6], P = 0.19). In patients with no pelvic nodes involved, chemotherapy and radiotherapy as single modalities were associated with similar DFS and overall survival. In patients with pelvic nodes, multimodality treatment was associated with better DFS than single modality treatment (0.3 [0.1-1], P = 0.05). CONCLUSION: pN3 penile cancer is a diverse prognostic group with poorer outcomes associated with pelvic nodes. Single modality adjuvant treatment may be adequate in inguinal nodes with extranodal extension, but multimodality treatment should be given in patients with pelvic nodal involvement.

Leishmaniasis is broadly classified into three types: cutaneous, mucocutaneous and visceral. The visceral form is most dangerous and can result in death. Although leishmaniasis is an ancient disease, its treatment is still challenging. Several drugs, differing in their cost, toxicity, treatment duration and emergence of drug resistance, are used for different types of leishmaniasis. To overcome these limitations, the search for newer drugs and other treatments continues. In this article, we discuss conventional drugs, other treatments, including newer options such as immunotherapy and immunochemotherapy, and future prospects for leishmaniasis treatment.

The objective of the study was to assess the outcome of carbohydrate loading dietary strategy on resistance exercise and muscle mass. In this prospective study, conducted at Dr DY Patil Gym and Fitness Center, Navi Mumbai (India), young healthy male resistance-trained individuals (18-25 years) were recruited randomly. The duration for entire study was three months in the year 2019. Participants were divided into two groups (n=30 each): carbohydrate loading group and control group. Participants in the carbohydrate loading group consumed carbohydrate loading diet protocol and designed exercise program for seven days. The control group consumed a regular diet with an exercise program. Resistance exercise (strength) and body circumference (muscle mass) measurements were recorded after seven days of respective assigned diet and exercise program. In the carbohydrate loading group, performance in resistance exercise was not significant from baseline to day seven (63.5±6.45 vs. 64.0±6.75 kg; p>0.05). Changes in the arm girth (p=0.3256), thigh girth (p=0.3256) and calf girth (p=0.1608) were also not significant in the carbohydrate loading group when compared from baseline to seven days. Therefore, the result indicates that the carbohydrate loading regimen had no enhanced effect on resistance exercise as well as muscle girth. This study results suggest that carbohydrate loading has no additional advantage in improving resistance exercise and muscle mass in resistance-trained individuals.

Accidental dural puncture following epidural insertion can cause a post-dural headache that is defined by the International Headache Society as self-limiting. We aimed to confirm if accidental dural puncture could be associated with persistent headache and back pain when compared with matched control parturients. We performed a prospective multicentre cohort study evaluating the incidence of persistent headache following accidental dural puncture at nine UK obstetric units. Parturients who sustained an accidental dural puncture were matched with controls who had undergone an uneventful epidural insertion. Participants were followed-up at six-monthly intervals for 18 months. Primary outcome was the incidence of persistent headache at 18 months. Ninety parturients who had an accidental dural puncture were matched with 180 controls. The complete dataset for primary analysis was available for 256 (95%) participants. Incidence of persistent headache at 18 months was 58.4% (52/89) in the accidental puncture group and 17.4% (29/167) in the control group, odds ratio (95%CI) 18.4 (6.0-56.7), p < 0.001, after adjustment for past history of headache, Hospital Anxiety and Depression Scale (depression) and Hospital Anxiety and Depression Scale (anxiety) scores. Incidence of low back pain at 18 months was 48.3% (43/89) in the accidental puncture group and 17.4% (29/167) in the control group, odds ratio (95%CI) 4.14 (2.11-8.13), with adjustment. We have demonstrated that accidental dural puncture is associated with long-term morbidity including persistent headache in parturients. This challenges the current definition of post-dural puncture headache as a self-limiting condition and raises possible clinical, financial and medicolegal consequences.

BACKGROUND: Membrane protrusions that occur on the dorsal surface of a cell are an excellent experimental system to study actin machinery at work in a living cell. Small GTPase Rac1 controls the membrane protrusions that form and encapsulate extracellular volumes to perform pinocytic or phagocytic functions. RESULTS: Here, capitalizing on rapid volumetric imaging capabilities of lattice light-sheet microscopy (LLSM), we describe optogenetic approaches using photoactivable Rac1 (PA-Rac1) for controlled ruffle generation. We demonstrate that PA-Rac1 activation needs to be continuous, suggesting a threshold local concentration for sustained actin polymerization leading to ruffling. We show that Rac1 activation leads to actin assembly at the dorsal surface of the cell membrane that result in sheet-like protrusion formation without any requirement of a template. Further, this approach can be used to study the complex morpho-dynamics of the protrusions or to investigate specific proteins that may be enriched in the ruffles. Deactivating PA-Rac1 leads to complex contractile processes resulting in formation of macropinosomes. Using multicolour imaging in combination with these approaches, we find that Myo1e specifically is enriched in the ruffles. CONCLUSIONS: Combining LLSM and optogenetics enables superior spatial and temporal control for studying such dynamic mechanisms. Demonstrated here, the techniques implemented provide insight into the complex nature of the molecular interplay involved in dynamic actin machinery, revealing that Rac1 activation can generate untemplated, lamellar protrusions.

Facial rejuvenation is gaining immense popularity among patients and clinicians. Botulinum toxins derived from bacteria are well-tolerated options as minimally invasive interventions for facial rejuvenation or other aesthetic procedures. These products have revolutionized aesthetic treatments. Several types of botulinum toxins (BoNT) are available. Currently type A and B are clinically used and only BoNTA products are approved for use for cosmetic indications in the Germany and the United States. Each product is unique in terms of its composition. Understanding the various BoNTA products is essential in choosing the optimal treatment for our patients. In this article we discuss different BoNTA products used for aesthetic intervention.
