RESUMEN

Enzymatic deamidation, the conversion of glutamine (Gln) into glutamic acid (Glu) residues, mediated by tissue transglutaminase enzymes, can provoke autoimmunity by generating altered self-epitopes, a process well-known in celiac disease and more recently also described in type 1 diabetes (T1D). To identify deamidated proteins, liquid chromatography-tandem mass spectrometry is the method of choice. However, as nonenzymatic deamidations on asparagine (Asn) and to a minor extent on Gln are frequently induced in vitro during proteomics sample preparation, the accurate detection of in vivo deamidation can be hampered. Here we report on the optimization of a method to reduce in vitro generated deamidation by 70% using improved trypsin digestion conditions (90 min/pH 8). We also point to the critical importance of manual inspection of MS2 spectra, considering that only 55% of the high quality peptides with Gln deamidation were assigned correctly using an automated search algorithm. As proof of principal, using these criteria, we showed a significant increase in levels of both Asn and Gln deamidation in cytokine-exposed murine MIN6 ß-cells, paralleled by an increase in tissue transglutaminase activity. These findings add evidence to the hypothesis that deamidation is occurring in stressed ß-cell proteins and can be involved in the autoimmune process in T1D.

RESUMEN

INTRODUCTION: Ivermectin is an antiparasitic drug which has in-vitro efficacy in reducing severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) viral load. Hence, Ivermectin is under investigation as a repurposed agent for treating COVID-19. METHODS: In this pilot, double blind, randomized controlled trial, hospitalized patients with mild-to-moderate COVID-19 were assigned to a single oral administration of an elixir formulation of Ivermectin at either 24 mg or 12 mg dose, or placebo in a 1:1:1 ratio. The co-primary outcomes were conversion of RT-PCR to negative result and the decline of viral load at day 5 of enrolment. Safety outcomes included total and serious adverse events. The primary outcomes were assessed in patients who had positive RT-PCR at enrolment (modified intention-to-treat population). Safety outcomes were assessed in all patients who received the intervention (intention-to-treat population). RESULTS: Among the 157 patients randomized, 125 were included in modified intention-to-treat analysis. 40 patients each were assigned to Ivermectin 24 mg and 12 mg, and 45 patients to placebo. The RT-PCR negativity at day 5 was higher in the two Ivermectin arms but failed to attain statistical significance (Ivermectin 24 mg, 47.5%; 12 mg arm, 35.0%; and placebo arm, 31.1%; p-value = 0.30). The decline of viral load at day 5 was similar in each arm. No serious adverse events occurred. CONCLUSIONS: In patients with mild and moderate COVID-19, a single oral administration of Ivermectin did not significantly increase either the negativity of RT-PCR or decline in viral load at day 5 of enrolment compared with placebo.

RESUMEN

BACKGROUND AND AIMS: Acute loss of smell or anosmia is a common and sometimes the only symptom observed in patients with coronavirus disease-2019 (COVID-19). The objective of the study was to determine the prevalence, time of onset, and duration of anosmia in patients with COVID-19 infection and the association of anosmia with other symptoms and eosinophil count. MATERIAL AND METHODS: Two hundred patients with laboratory-confirmed COVID-19 infection, who were asymptomatic or mildly symptomatic were assessed for olfaction with a nonirritant odor. The presence of anosmia was recorded, and a questionnaire integrating the anosmia reporting tool was filled. Patients with anosmia/hyposmia were followed telephonically at 7 and 14 days for resolution of anosmia and other symptoms. The presence of anosmia was correlated with eosinophil count. RESULTS: Of the 200 COVID-19 patients, 87% were symptomatic. More than half of the patients had fever (56%). Anosmia was observed in 30% of the patients and hyposmia in 4% of patients. In 41% of the patients, olfactory loss was reported before diagnosis. The mean duration of anosmia was 7.8 (± 5) days; 97% of patients recovered with a resolution of symptoms within 2 weeks. Ageusia was the most commonly and significantly associated symptom with anosmia (66%, n = 45) followed by sore throat (41%), and rhinorrhea (28%). The symptoms in both the sexes were comparable. Absolute eosinophil count of <40/µL was observed in 59 patients (29.5%) and an absolute eosinophil count of 0 in 17 patients (8.5%). Among the 68 anosmic patients, 36 (47%) patients had eosinopenia, which was statistically significant. CONCLUSION: Anosmia is an early and sometimes the only symptom in approximately one-third of the patients with COVID-19 infection. Eosinophil count should be checked in anosomic patient with suspicion of COVID-19 infection. Objective tools for olfactory and gustatory assessment should be brought into practice for early and prompt diagnosis to control the spread of the disease.

RESUMEN

BACKGROUND & OBJECTIVES: In December 2019, a novel coronavirus (SARS-CoV-2) emerged in China and rapidly spread globally including India. The characteristic clinical observations and outcomes of this disease (COVID-19) have been reported from different countries. The present study was aimed to describe the clinico-demographic characteristics and in-hospital outcomes of a group of COVID-19 patients in north India. METHODS: This was a prospective, single-centre collection of data regarding epidemiological, demographic, clinical and laboratory parameters, management and outcome of COVID-19 patients admitted in a tertiary care facility in north India. Patient outcomes were recorded as death, discharge and still admitted. RESULTS: Data of 144 patients with COVID-19 were recorded and analyzed. The mean age of the patients was 40.1±13.1 yr, with 93.1 per cent males, and included 10 (6.9%) foreign nationals. Domestic travel to or from affected States (77.1%) and close contact with COVID-19 patients in congregations (82.6%) constituted the most commonly documented exposure. Nine (6.3%) patients were smokers, with a median smoking index of 200. Comorbidities were present in 23 (15.9%) patients, of which diabetes mellitus (n=16; 11.1%) was the most common. A significant proportion of patients had no symptoms (n=64; 44.4%); among the symptomatic, cough (34.7%) was the most common symptom followed by fever (17.4%) and nasal symptoms (2.15%). Majority of the patients were managed with supportive treatment with hydroxychloroquine and azithromycin given on a case-to-case basis. Only five (3.5%) patients required oxygen supplementation, four (2.8%) patients had severe disease requiring intensive care, one required mechanical ventilation and mortality occurred in two (1.4%) patients. The time to reverse transcription-polymerase chain reaction (RT-PCR) negativity was 16-18 days. INTERPRETATION & CONCLUSIONS: In this single-centre study of 144 hospitalized patients with confirmed COVID-19 in north India, the characteristic findings included younger age, high proportion of asymptomatic patients, long time to PCR negativity and low need for intensive care unit care.

RESUMEN

A 47-year-old patient was referred from otorhinolaryngologist with a chief complaint of hearing loss to the medical oncology department where he was diagnosed to have nasopharyngeal carcinoma (NPC). The patient was given six cycles of chemotherapy and 35# of radiotherapy. After a week of therapies, he developed a low-grade fever. He was suspected of COVID-19, but the reverse transcription polymerase chain reaction test came out to be negative. He developed urinary retention, and he was planned for suprapubic catheterization. Before the procedure, he was retested for COVID-19 which came out to be positive. This case report aims to describe the condition of a patient of NPC with COVID-19 infection and to discuss the outcome of disease in this circumstance.

RESUMEN

INTRODUCTION: The World Health Organization has declared severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as a pandemic. The interventions employed by various health authorities in combating the infection may help in eliminating the threat; however, they have long-term cognitive and mental health effects on the population. AIMS: The primary objective was to assess the prevalent concerns and coping strategies and perspectives in persons suspected of SARS-CoV-2 infection under institutional quarantine in India during the period from April 2020 to May 2020. SETTING AND DESIGN: Its a cross-sectional observational study conducted in the National Cancer Institute, Jhajjar, India. METHODOLOGY: After ethical clearance, convenience sampling was done. Relevant demographic details were obtained. Health-care professionally administered questionnaire to assess psychological concerns and coping mechanisms. All statistics are deemed to be descriptive only. RESULTS: The most common physical concern was fever seen in 37% of respondents, followed by cough in 31% and sore throat in 29%. In terms of emotional concerns, 55.3% of respondents were worried and 43% were anxious and 33% were sad. About 80.6% of participants selected support from family and friends helped them cope during the institutional quarantine. 57% maintained a daily routine, 70% selected praying, and 45% used music as a coping strategy. Only 2% felt that they were unable to cope. CONCLUSION: It highlights that the psychological impact of illness on affected individuals should not be overlooked as it may have the potential to cause major psychiatric morbidity. It also provides a crucial assessment of their coping mechanisms.

RESUMEN

The COVID-19 outbreak is an unexpected challenge to all areas of health-care delivery, including cancer centers. The novel coronavirus is known to affect individuals in all age groups, especially patients with multiple comorbidities. A nationwide lockdown has restricted the routine patient care, with health-care services focusing mainly on emergency services and COVID patient management. These restrictions in health services may delay the treatments of non-COVID patients. This conundrum is especially true in cancer patients as they require frequent visits to the hospital, and there is a lack of understanding of the treatment prioritization in cancer patients. In this case, we discuss the concerns faced by a 37-year-old male with neuroendocrine tumor of the anal canal who was tested COVID positive. His surgery was canceled following the report and was shifted to the COVID care facility. Best supportive care was given till further management.

RESUMEN

CONTEXT: The coronavirus pandemic has put an unprecedented burden on the health-care workers who are the cornerstone of the work system, preparing to mitigate its effects. Due to the lack of protective equipments, guidelines for managing patients, or proper training and education regarding the same, health care professionals (HCPs) working in non-COVID areas may face even greater problems than those working in COVID areas of a hospital. Our aim was to find out the concerns of HCPs working in non-COVID areas. SUBJECTS AND METHODS: After obtaining institutional ethics approval, a descriptive cross-sectional study was planned. An online Google-based questionnaire was rolled out to all doctors through various social media platforms who were dealing with COVID-negative patients. RESULTS: We received a total of 110 responses. 84.5% of participants were concerned about the risk of infection to self and family, 67.3% were concerned by the disruption of their daily activities. 56.4% of HCPs were disturbed by the lack of any concrete protocol for patient management. Less staff availability, delay in discharging duties toward their patients, and increased workload were other concerns. More than half of the doctors received N-95 masks whenever required and were trained in donning and doffing of Personal protective equipment. Sixty-eight percemt of our respondents labeled their current quality of life as stressful. CONCLUSION: It is the need of the hour to develop a comprehensive strategy focussing on the above challenges that HCPs working in non-COVID areas are facing. This will go a long way in not only providing holistic care to the patients but also in controlling this pandemic.

RESUMEN

BACKGROUND: Breast cancer is the most common malignancy among women. Chronic pain after breast surgeries is a well-known entity and is mainly neuropathic in nature. The primary aim of this study was to assess the effect of pregabalin given as preventive analgesic on the incidence of chronic postmastectomy pain. METHODS: A randomized control trial (RCT) was performed on 80 patients. Patients were allocated into two groups. Group 1 received pregabalin (Lyrica, Pfizer) 75 mg. BD starting from the morning of surgery and continued for 1 week. Group 2 received placebo capsules at identical time intervals. Patients were followed up for 3 months postoperatively. Incidence, severity, and location of chronic pain were recorded. The primary objective was to evaluate the effect of perioperative oral pregabalin on the incidence of chronic postmastectomy pain (at 3 months postoperatively). RESULTS: Of the 80 patients enrolled, 71 patients completed the study and were assessed for final outcomes. Incidence of chronic pain was comparable in both groups, with 16 out of 35 patients in Group 1 (44.7%) and 20 out of 36 patients in Group 2 (55.6%) reported chronic pain (P = 0.407). There was no difference between the severity of chronic pain (numeric rating scale ≥ 4) in both groups (P = 0.307). Incidence of adverse effects was comparable in both groups. CONCLUSION: This RCT shows that perioperative pregabalin may not have a role in the prevention of chronic pain after breast surgeries.

RESUMEN

AIMS/HYPOTHESIS: Type 1 diabetes is an endocrine disease where a long preclinical phase, characterised by immune cell infiltration in the islets of Langerhans, precedes elevated blood glucose levels and disease onset. Although several studies have investigated the role of the immune system in this process of insulitis, the importance of the beta cells themselves in the initiation of type 1 diabetes is less well understood. The aim of this study was to investigate intrinsic differences present in the islets from diabetes-prone NOD mice before the onset of insulitis. METHODS: The islet transcriptome and proteome of 2-3-week-old mice was investigated by microarray and 2-dimensional difference gel electrophoresis (2D-DIGE), respectively. Subsequent analyses using sophisticated pathway analysis and ranking of differentially expressed genes and proteins based on their relevance in type 1 diabetes were performed. RESULTS: In the preinsulitic period, alterations in general pathways related to metabolism and cell communication were already present. Additionally, our analyses pointed to an important role for post-translational modifications (PTMs), especially citrullination by PAD2 and protein misfolding due to low expression levels of protein disulphide isomerases (PDIA3, 4 and 6), as causative mechanisms that induce beta cell stress and potential auto-antigen generation. CONCLUSIONS/INTERPRETATION: We conclude that the pancreatic islets, irrespective of immune differences, may contribute to the initiation of the autoimmune process. DATA AVAILABILITY: All microarray data are available in the ArrayExpress database ( www.ebi.ac.uk/arrayexpress ) under accession number E-MTAB-5264.

RESUMEN

INTRODUCTION: Auto-immunity against pancreatic beta-cells leads to an absolute shortage of the hormone insulin, resulting in hyperglycemia and the onset of type 1 diabetes (T1D). Proteomic approaches have been used to elucidate the mechanisms of beta-cell dysfunction and death. Areas covered: In the present review, we discuss discoveries in the beta-cell proteome that have contributed to better insights in the role of the beta-cell in T1D. Techniques, such as 2D-DIGE and MALDI imaging, together with new approaches for sample preparation, including laser capture microdissection and immunopeptidomics, have resulted in novel mechanistic insights in the pathogenesis of T1D. We describe how proteomic studies in beta-cell lines as well as isolated islets from animal models and humans have discovered intracellular signaling pathways leading to beta-cell destruction, the generation of neo-antigens through post-translational modifications of beta-cell antigens as well as better biomarkers of disease progression. Expert commentary: Proteomics has contributed to the discovery of beta-cell neo-autoantigen generation through post-translational modifications, hybrid insulin peptide formation and the generation of defective ribosomal gene products. These concepts are revolutionizing our insights in the pathogenesis of T1D, acknowledging a central role for the beta-cell in its own destruction.

RESUMEN

AIM OF THE STUDY: To study the effect of scrambler therapy on patients with chronic cancer pain. MATERIALS AND METHODS: This is a prospective, observational study conducted on patients with chronic pain due to malignancy which is not responding to oral analgesics. A total of twenty patients were included in the study (ten males, ten females) with a visual analog scale score of >4 on oral analgesics. Patients aged 18-70 years with a life expectancy of >3 months having bony, neuropathic, or mixed type of pain were included in the study. A total of 12 sessions of scrambler therapy were planned, ten sessions on consecutive days and one session each on two follow-up visits after 1 week each. Each session lasted for 40 min. Pain relief and quality of life according to the World Health Organization Quality of Life were recorded as primary outcome variables. RESULTS: All patients had good pain relief and improvement in all four domains of quality of life. Pain scores decreased significantly (P < 0.01) after each session and at each follow-up. Patients showed significant improvement in physical, psychological, social, and environmental health (P < 0.01) after the therapy. CONCLUSION: Scrambler therapy offers a promising role in the pain physician's armamentarium as an adjunct to pharmacological therapy for the treatment of chronic drug-resistant cancer pain; it may bring down analgesic drug requirements significantly and improve quality of life in cancer patients. Larger prospective, randomized multicenter studies are needed to validate the findings of the small pilot studies published in literature so far.

RESUMEN

Enhanced Recovery After Surgery (ERAS) protocols have emerged as a promising approach to optimize perioperative care and improve outcomes in various surgical specialties. Despite feasibility studies on ERAS in various surgeries, there remains a paucity of research focusing on gastrointestinal cancer surgeries in the Indian context. The primary objective is to evaluate the compliance rate of the ERAS protocol and secondary objectives include the compliance rate of individual components of the protocol, the complications, the length of hospital stay, and the challenges faced during implementation in patients undergoing gastrointestinal cancer surgeries in our tertiary care cancer center. In this prospective interventional study (CTRI/2022/04/041657; registered on 05/04/2022), we evaluated 50 patients aged 18 to 70 years undergoing surgery for gastrointestinal malignancies and implemented a refined ERAS protocol tailored to our institutional resources and conditions based on standard ERAS society recommendations for gastrointestinal surgeries and specific recommendations for colorectal, pancreatic, and esophageal surgeries.Our study's mean overall compliance rate with the ERAS protocol was 88.54%. We achieved a compliance rate of 91.98%, 81.66%, and 92.00% for pre-operative, intraoperative, and post-operative components respectively. Fourteen (28%) patients experienced complications during the study. The median length of stay was 6.5 days (5.25-8). Challenges were encountered during the preoperative, intraoperative, and postoperative phases. The study highlighted the feasibility of implementing the ERAS protocol in a cancer institute, but specific challenges need to be addressed for its optimal success in gastrointestinal cancer surgeries. Supplementary Information: The online version contains supplementary material available at 10.1007/s13193-024-01897-y.

RESUMEN

Swati BhanIntroduction This paper aims to provide an overview of the administrative and clinical preparations done in a tertiary care cancer hospital in continuing operation theatre (OT) services through the COVID pandemic. Methods Retrospective data collection, data for the past 1.5 years (COVID period) March 2020 to August 2021 were compared to surgical output for a similar duration of time before the COVID era (September 2018-February 2020). Results A total of 1,022 surgeries were done under anesthesia in the COVID period as against 1,710 surgeries done in a similar time frame in the pre-COVID era. Overall, we saw a 40%drop in the total number of cases. Thorax, abdominal, and miscellaneous surgeries (soft tissue sarcomas, urology, and gyneconcology) saw a maximum fall in numbers; however, head and neck cases saw an increase in numbers during the pandemic. Surgical morbidity and mortality were similar in the COVID and pre-COVID era. No cases of severe COVID infection were reported among the healthcare staff working in OT. Discussion We could successfully continue our anesthesia services with minimal risk to healthcare staff throughout the pandemic by adopting major guidelines in a pragmatic and practical approach with minor changes to suit our setup.

RESUMEN

The ß-cell plays a crucial role in the pathogenesis of type 1 diabetes, in part through the posttranslational modification of self-proteins by biochemical processes such as deamidation. These neoantigens are potential triggers for breaking immune tolerance. We report the detection by LC-MS/MS of 16 novel Gln and 27 novel Asn deamidations in 14 disease-related proteins within inflammatory cytokine-stressed human islets of Langerhans. T-cell clones responsive against one Gln- and three Asn-deamidated peptides could be isolated from peripheral blood of individuals with type 1 diabetes. Ex vivo HLA class II tetramer staining detected higher T-cell frequencies in individuals with the disease compared with control individuals. Furthermore, there was a positive correlation between the frequencies of T cells specific for deamidated peptides, insulin antibody levels at diagnosis, and duration of disease. These results highlight that stressed human islets are prone to enzymatic and biochemical deamidation and suggest that both Gln- and Asn-deamidated peptides can promote the activation and expansion of autoreactive CD4+ T cells. These findings add to the growing evidence that posttranslational modifications undermine tolerance and may open the road for the development of new diagnostic and therapeutic applications for individuals living with type 1 diabetes.

RESUMEN

Tracheal diverticulum is usually detected incidentally. Rarely, it may lead to difficulty in securing the airway intraoperatively. Our patient underwent oncological resection under general anaesthesia for advanced oral cancer. Elective tracheostomy was performed at the end of the surgery, and a cuffed tracheostomy tube (T-tube) of 7.5 mm size was inserted through the tracheostoma. Despite repeated attempts at T-tube insertion, ventilation could not be established. However, on advancing the endotracheal tube beyond tracheostoma, ventilation was restored. The T-tube was inserted into the trachea under fibreoptic guidance achieving successful ventilation. A fibreoptic bronchoscopy through the tracheostoma performed after decannulation revealed a mucosalised diverticulum extending behind the posterior wall of the trachea. The bottom of the diverticulum showed mucosa-lined cartilaginous ridge with differentiation into smaller bronchiole-like structures. Tracheal diverticulum should be considered as a possible differential in case of failed ventilation following an otherwise uneventful tracheostomy.

RESUMEN

Background COVID-19 has spread as two distinct surges of cases in many countries. Several countries have reported differences in disease severity and mortality in the two waves. Objective Compare the in-hospital mortality in the two COVID-19 waves at a tertiary care hospital in India. Methods We conducted a retrospective data collection. Distinct periods of surges in cases and admissions were defined as the first wave spanning from March 2020 to December 2020 and the second wave from April 2021 to June 21, 2021. The primary outcome of this study was to compare mortality rates in terms of total hospital mortality rate (TMR) and case fatality rate (CFR). Results Mortality rates of wave 2 were approximately 10 times that of wave 1 (TMR of 20.3% in wave 2 versus 2.4% in wave 1 and CFR of 1.5% versus 17.7% in wave 1 and 2, respectively). Mortalities in wave 2 had a larger proportion of severe disease at presentation, faster progression of symptoms to death, and more patients without any chronic comorbid condition dying due to the direct effect of COVID-19 acute respiratory distress syndrome (ARDS). Conclusion Our data matches the worldwide reported pooled hospital mortality figures and shows the comparative difference in disease severity between the two waves.

RESUMEN

OBJECTIVE: Intubation is a highly aerosol-generating procedure. Recent airway management guidelines advocate the use of appropriate personal protective equipment, videolaryngoscope, and "intubation box" while intubating a suspected or infected coronavirus patient. We undertook a study to compare C-MAC videolaryngoscope with McGrath videolaryngoscope for tracheal intubation using an intubation box by donned anaesthesiologists. METHODS: The patients were randomly allocated to 2 groups by computer-generated random numbers, depending upon the videolaryngoscope used. In group C, C-MAC videolaryngoscope (n=30) was used, whereas McGrath videolaryngoscope was used in group M (n=30). The primary outcome was the total time required for successful intubation. The secondary outcomes included the number of attempts required, Cormack and Lehane grade, the percentage of glottis opening score, the difficulty faced while using the device, and the user's preference. RESULTS: The time to intubation was 57.17 ± 19.98 seconds with C-MAC videolaryngoscope as compared to 57.93 ± 14.92 seconds with McGrath. Both the devices had a good percentage of glottis opening score. Twelve patients in each group were found to have a Cormack and Lehane grade of 1. The time to glottis visualization was more with McGrath than with C-MAC although not significant (23.8 ± 14.03 vs 20.10 ± 10.78 seconds). Both the devices were easy to use. CONCLUSIONS: Both C-MAC and McGrath videolaryngoscopes are equally effective devices for intubation by a donned anaesthesiologist using an intubation box. McGrath with a disposable blade should be preferred for intubation in these conditions.
