RESUMEN

In the face of agricultural challenges posed by both abiotic and biotic stressors, phytopathogens emerge as formidable threats to crop productivity. Conventional methods, involving the use of pesticides and microbes, often lead to unintended consequences. In addressing this issue, ICAR -Indian Institute of Oilseeds Research (ICAR-IIOR) has developed a chitosan-based double-layer seed coating. Emphasizing crop input compatibility, entrapment, and characterization, the study has yielded promising results. The double-layer coating on groundnut seeds enhanced germination and seedling vigor. Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) confirmed the structural changes and entrapment of crop inputs. The persistence of T. harzianum (Th4d) and Bradyrhizobium sp. in chitosan blended film in studied soils revealed that viable propogules of Th4d were recorded in double layer treatment combination with 3.54 and 3.50 Log CFUs/g of soil (colony forming units) and Bradyrhizobium sp. with 5.34 and 5.27 Log CFUs/g of soil at 90 days after application (DAA). Root colonization efficacy studies of Th4d and Bradyrhizobium sp. in groundnut crop in studied soils revealed that, maximum viable colonies were observed at 45 days after sowing (DAS). This comprehensive study highlights the potential of chitosan-based double-layer seed coating providing a promising and sustainable strategy for stress management in agriculture.

RESUMEN

BACKGROUND: While factors associated with long COVID (LC) continue to be illuminated, little is known about recovery. This study used national survey data to assess factors associated with recovery from LC. METHODS: We used data from the 2022 National Health Interview Survey, a cross-sectional sample of noninstitutionalized US adults. Survey analysis was used to account for oversampling and nonresponse bias and to obtain nationally representative estimates. A multivariable logistic regression model was used to identify potential predictors of LC recovery. RESULTS: Among those reporting ever having COVID-19, 17.7% or an estimated 17.5 million American adults reported ever having LC, and among those with LC, 48.5% or an estimated 8.5 million reported having recovered. Multivariable logistic regression analysis showed that Hispanic adults were significantly more likely than White adults to report recovery from LC. At the same time, those with severe COVID-19 symptoms and those who had more than a high school degree, were aged 40 years or older, or were female were less likely to report recovery. CONCLUSION: Significant variations in LC recovery were noted across age, sex, race and ethnicity, education, and severity of COVID-19 symptoms. Further work is needed to elucidate the causes of these differences and identify strategies to increase recovery rates.

RESUMEN

Diabetic kidney disease (DKD), or diabetic nephropathy (DN), is one of the most prevalent complications of type 2 diabetes mellitus (T2DM) and causes severe burden on the general welfare of T2DM patients around the world. While several new agents have shown promise in treating this condition and potentially halting the progression of the disease, more work is needed to understand the complex regulatory network involved in the disorder. Recent studies have provided new insights into the connection between autophagy, a physiological metabolic process known to maintain cellular homeostasis, and the pathophysiological pathways of DKD. Typically, autophagic activity plays a role in DKD progression mainly by promoting an inflammatory response to tissue damage, while both overactivated and downregulated autophagy worsen disease outcomes in different stages of DKD. This correlation demonstrates the potential of autophagy as a novel therapeutic target for the disease, and also highlights new possibilities for utilizing already available DN-related medications. In this review, we summarize findings on the relationship between autophagy and DKD, and the impact of these results on clinical management strategies.

RESUMEN

Aging is a complex process involving transcriptomic changes associated with deterioration across multiple tissues and organs, including the brain. Recent studies using heterochronic parabiosis have shown that various aspects of aging-associated decline are modifiable or even reversible. To better understand how this occurs, we performed single-cell transcriptomic profiling of young and old mouse brains after parabiosis. For each cell type, we cataloged alterations in gene expression, molecular pathways, transcriptional networks, ligand-receptor interactions and senescence status. Our analyses identified gene signatures, demonstrating that heterochronic parabiosis regulates several hallmarks of aging in a cell-type-specific manner. Brain endothelial cells were found to be especially malleable to this intervention, exhibiting dynamic transcriptional changes that affect vascular structure and function. These findings suggest new strategies for slowing deterioration and driving regeneration in the aging brain through approaches that do not rely on disease-specific mechanisms or actions of individual circulating factors.

RESUMEN

As the rate of natural disasters and other devastating events caused by human activities increases, the burden on the health and well-being of those affected by kidney disease has been immeasurable. Health system preparedness, which involves creating a resilient system that is able to deal with the health needs of the entire community during times of unexpected disruptions to usual care, has become globally important. In the wake of the COVID-19 pandemic, there is a heightened awareness of the amplification of negative effects on the renal community. Paradoxically, the complex medical needs of those who have kidney diseases are not met by systems handling crises, often compounded by an acute increase in burden via new patients as a result of the crisis itself. Disruptions in kidney care as a result of unexpected events are becoming more prevalent and likely to increase in the years to come. It is therefore only appropriate that the theme for this year's World Kidney Day will focus on Kidney Health for All: preparedness for the unexpected in supporting the vulnerable.

RESUMEN

BACKGROUND: Percutaneous Endoscopic Gastrostomy (PEG) tubes are often placed for dysphagia following a stroke in order to maintain sufficient caloric intake. The 2011 ASGE guidelines recommend delaying PEG tube placement for two weeks, as half of patients with dysphagia improve within 2 wk. There are few studies comparing outcomes based on timing of PEG tube placement, and there is increasing demand for early PEG tube placement to meet requirements for timely discharge to rehab and skilled nursing facilities. AIM: To assess the safety of early (≤ 7 d post stroke) vs late (> 7 d post stroke) PEG tube placement and evaluate whether pre-procedural risk factors could predict mortality or complications. METHODS: We performed a retrospective study of patients undergoing PEG tube placement for dysphagia following a stroke at two hospitals in Saint Louis, MO between January 2011 and December 2017. Patients were identified by keyword search of endoscopy reports. Mortality, peri-procedural complication rates, and post-procedural complication rates were compared in both groups. Predictors of morbidity and mortality such as protein-calorie malnutrition, presence of an independent cardiovascular risk equivalent, and presence of Systemic inflammatory response syndrome (SIRS) criteria or documented infection were evaluated by multivariate logistic regression. RESULTS: 154 patients had a PEG tube placed for dysphagia following a stroke, 92 in the late group and 62 in the early group. There were 32 observed deaths, with 8 occurring within 30 d of the procedure. There was an increase in peri-procedural and post-procedural complications with delayed PEG placement which was not statistically significant. Hospital length of stay was significantly less in patients with early PEG tube placement (12.9 vs 22.34 d, P < 0.001). Protein calorie malnutrition, presence of SIRS criteria and/or documented infection prior to procedure or having a cardiovascular disease risk equivalent did not significantly predict mortality or complications. CONCLUSION: Early PEG tube placement following a stroke did not result in a higher rate of mortality or complications and significantly decreased hospital length of stay. Given similar safety outcomes in both groups, early PEG tube placement should be considered in the appropriate patient to potentially reduce length of hospital stay and incurred costs.

RESUMEN

Background: Children residing in orphanages often have accumulated oral health needs as they are unaware of the importance of maintaining good oral hygiene. Due to financial constraints, the provision of oral health care is often neglected. Aims and Objectives: This study attempts to assess the perception of oral health and practices among children residing in orphanages in Bengaluru. Materials and Methods: A cross-sectional survey was conducted among 269 inmates, which assessed their perception and practices concerning oral health. Results: The self-assessment and practices of the study participants varied significantly. The proportion of substance abuse was very low, and the oral hygiene practices of the majority of participants were good. Conclusion: Interventions need to be undertaken to improve and reinforce oral health awareness among the study participants.

RESUMEN

BACKGROUND: During the coronavirus disease 2019 pandemic, national guidelines recommended that elective surgery for esophageal cancer be deferred by 3 months when hospital resources are limited. The impact of this delay on patient outcomes is unknown. We sought to evaluate the survival of patients with stage I and II/III esophageal cancer who undergo early vs delayed treatment. STUDY DESIGN: Using the National Cancer Database from 2010 to 2017, multivariable Cox proportional hazards modeling and propensity score-matched analysis were employed to compare survival of patients with stage I esophageal cancer who received early (0 to 4 weeks after diagnosis) vs delayed esophagectomy (12 to 16 weeks) and of patients with stage II/III esophageal cancer who-after receiving timely chemoradiation (0 to 4 weeks after diagnosis)-underwent early (9 to 17 weeks) vs delayed esophagectomy (21 to 29 weeks). RESULTS: For stage I esophageal cancer, 226 (41.7%) patients underwent early esophagectomy, and 316 (58.3%) patients underwent delayed esophagectomy. Propensity score matching created 2 groups of 134 patients with early or delayed esophagectomy, whose 5-year survival was comparable (hazard ratio [HR] 65.0% [95% confidence interval (CI) 55.2% to 73.2%] vs HR 65.1% [95% CI 55.6% to 73.1%], p = 0.50). For stage II/III esophageal cancer, 1,236 (86.1%) patients underwent early esophagectomy, and 200 (13.9%) underwent delayed esophagectomy. Propensity score matching created 2 groups of 130 patients; the early esophagectomy group had improved 5-year survival compared with the delayed esophagectomy group (HR 41.6% [95% CI 32.1% to 50.8%] vs HR 22.9% [95% CI 14.9% to 31.8%], p = 0.006). CONCLUSIONS: Early esophagectomy was associated with similar survival compared with delayed esophagectomy for patients with stage I esophageal cancer. For patients with stage II/III esophageal cancer, early esophagectomy was associated with improved survival relative to delayed esophagectomy.

RESUMEN

We report the first case of Coronavirus Disease 2019 (COVID-19)-associated brain abscess caused by a rare Trichosporon species, T. dohaense. The patient was a known diabetic and had received systemic corticosteroids for the treatment of COVID-19. He underwent craniotomy and evacuation of abscess. The pus aspirate grew a basidiomycetous yeast, morphologically resembling Trichosporon species. The isolate was initially misidentified by VITEK® MS due to lack of mass spectral database of T. dohaense. Accurate identification was achieved by internal transcribed spacer-directed panfungal polymerase chain reaction. The patient had a favorable outcome following surgical intervention and antifungal therapy.

RESUMEN

PURPOSE: To evaluate the efficacy of oral propranolol in the treatment of periocular infantile capillary hemangioma (CHI) based on the involvement of embryological facial placodes and their extent of anatomical involvement. METHODS: Retrospective study of 27 patients. RESULTS: The mean age at the presentation of periocular CHI was 4 months (median, 3 months; range, <1-14 months). There were 11 (41%) males and 16 (59%) females. Based on embryological facial placodes, the involvement was focal in 16 (59%) cases and segmental in 11 (41%) cases. Based on the anatomical distribution, the lesions were preseptal in 4 (15%), postseptal in 13 (48%), and combined in 10 (37%) cases. The duration of use of oral propranolol was 10 months (median, 10 months; range, 4-16 months). Overall, the mean % resolution of periocular CHI was 78% (median, 90%; range, 20%-100%). The mean percentage resolution of focal lesions was 69% (median, 83%; range, 20%-100%), and segmental lesions were 92% (median, 95%; range, 70%-100%). The mean percentage resolution of preseptal component of lesions was 94% (median, 95%; range, 80%-100%) and postseptal component was 74% (median, 85%; range, 20%-100%) over a mean follow-up period of 16 months (median, 15 months; range, 4-37 months). Four (15%) patients exhibited flare-up of lesion after tapering oral propranolol. CONCLUSION: Oral propranolol is effective in the treatment of periocular CHI. Segmental and preseptal lesions respond better to the treatment compared to focal and postseptal lesions.

RESUMEN

Intussusception more commonly occurs in pediatrics but is a rare cause of bowel obstruction and gastrointestinal bleeding in adults. It typically occurs in adults due to a malignancy, which serves as a pathologic lead point. We present a case of a 64-year-old female with nausea, vomiting, and melena who was found to have intussusception associated with a primary jejunal amelanotic melanoma. Both intussusception and primary small bowel melanomas are rare causes of obstruction and bleeding. Intussusception occurring as a result of a primary small bowel amelanotic melanoma is exceedingly rare with very few reported cases. We provide a case report and review of the literature.

RESUMEN

BACKGROUND: Confluent and reticulate papillomatosis (CRP) is an uncommon benign, acquired keratinization disorder. Studies on this disorder are lacking except for a few case reports and there is a paucity of Indian literature on the condition. OBJECTIVES/METHODS: To study and describe the various morphological patterns and histopathological findings, as well as assess the response to treatment of 30 patients diagnosed with CRP. RESULTS: Thirtypatients with a diagnosis of confluent and reticulate papillomatosis were included in the study. The male to female ratio was 1:1.5. Mean age at onset of skin eruptions was 27.3 years and mean duration of skin eruptions was 8.2 months. Most of the patients (60%) were asymptomatic. The majority (66.7%) had lesions distributed over upper trunk. Two-thirds of patients had typical brown macules in confluent and reticulate pattern. KOH mount was done in 24 cases and was positive in three cases (12.5%) for yeast-like hyphae. Biopsy demonstrated variable degrees of hyperkeratosis, papillomatosis, and moderate acanthosis. Thirteen out of eighteenpatients on minocycline showed complete clearance within 3 weeks andthreepatients had more than 50% improvement at the end of 3 weeks. Doxycycline showed satisfactory response but results were less satisfactory with azithromycin. CONCLUSION: CRP is an uncommon condition. There is a paucity of large studies in Indian literature. The present study highlightssuch a large cohort of cases. Prevalence of CRP was more in female in contrast to western studies. Association of CRP with hyperthyroidism was described in many studies but the present study highlights the association with hypothyroidism. Morphological variants like shiny atrophic lesions, verrucous lesions, and involvement of atypical sites like forearm have been described. Role of minocycline in the management of chronic and recurrent cases has been reinforced.

RESUMEN

Mycophenolate mofetil (MMF) is associated with various gastrointestinal toxicities. However, limited literature studies exist reporting MMF-related gastrointestinal toxicity manifesting as esophageal strictures. We report a case of a 62-year-old male with kidney transplant on MMF, tacrolimus, and prednisone, presenting with progressive dysphagia and odynophagia. Esophagogastroduodenoscopy revealed severe esophageal stricturing with near food bolus impaction, requiring dilations, esophageal stent, and ultimately gastrostomy tube. Biopsies revealed nonspecific inflammation with no evidence of infectious/neoplastic process; thus, our multidisciplinary esophageal group determined that the process was secondary to MMF. This case demonstrates that, though rare, MMF can result in severe esophageal strictures causing significant morbidity.

RESUMEN

BACKGROUND AND AIM: Same-day double upper and lower gastrointestinal endoscopy is frequently performed due to overlapping indications. However, it is unclear whether an upper-lower (U-L) or lower-upper (L-U) sequence is optimal. We analyzed the effect of sequence on total procedure time and sedation use. METHODS: A total of 100 patients scheduled for same-day double endoscopy were randomized to the U-L or L-U sequence arm. Primary outcomes, mean total procedure time, and sedative dosages were compared using a t-test. We also explored associations of the primary outcomes with patient-related and procedure-related factors. RESULTS: Comparing U-L and L-U sequences, mean total procedure time was 41.9 (16.2) versus 43.0 (14.5) min (P = 0.73), diphenhydramine dose 5.5 (15.4) versus 4.5 (14.0) mg (P = 0.74), fentanyl dose 71.5 (119.3) versus 77.6 (164.02) µg (P = 0.83), midazolam dose 1.6 (2.5) versus 1.4 (2.7) mg (P = 0.69), and propofol dose 437.4 (351.4) versus 444.5 (256.0) mg (P = 0.91), respectively. Total procedure and upper endoscopy times were significantly longer with trainee presence (P = 0.0002) and shorter with conscious sedation (P = 0.003). Upper endoscopy time was longer with higher body mass index (P = 0.001), and lower endoscopy time was longer in patients with cirrhosis or chronic kidney disease (P = 0.002 and 0.009, respectively). Time between procedures was significantly longer in the L-U sequence (7.4 [2.9] vs 5.3 [1.1] min, [P < 0.001]). The study had 80% power to detect an 8 min difference in total procedure time. CONCLUSIONS: The sequence of same-day double gastrointestinal endoscopy does not affect total procedure time or medication use. Longer total procedure and upper endoscopy times were associated with trainee presence and use of conscious sedation.

RESUMEN

Intraductal papillary mucinous neoplasms (IPMN) of the pancreas are characterized by proliferation of mucin-secreting cells in the main pancreatic duct (PD) or its branches. The secreted thick mucin usually leads to PD obstruction and dilation. A common complication of IPMN is recurrent acute pancreatitis secondary to poor pancreatic fluid drainage, and rarely, pancreatobiliary and pancreatointestinal fistulae. We describe a unique case of IPMN in a 57-year-old male who was referred to our institution for evaluation of recurrent acute pancreatitis. After extensive evaluation, he was diagnosed with main duct IPMN. Intraductal PD biopsy revealed intestinal type IPMN with intermediate grade dysplasia. Patient was managed clinically by large caliber (10 French) PD stenting which eliminated his recurrent acute pancreatitis. The patient was initially referred for pancreatic resection; however, surgery was aborted and evaluated to be high risk with high morbidity secondary to the extensive adhesions between the pancreas and surrounding structures. Patient remained clinically stable for a few years except for an episode of acute pancreatitis that happened after a trial of stent removal. Subsequently, the patient did well after the PD stent was replaced. Recently, repeat abdominal imaging revealed a large pancreatoduodenal fistula which was confirmed on repeat endoscopic retrograde cholangiopancreatography. We were able to perform pancreatoscopy by advancing a regular upper scope through the fistula and into the PD. Interestingly, the fistula relieved the symptoms of obstruction and subsequently decreased the frequency of recurrent pancreatitis episodes with no further episodes at 6 months follow-up. This case highlights the importance of providing adequate PD drainage to reduce the frequency of recurrent acute pancreatitis in the setting of main duct IPMN, especially if the patient is not a surgical candidate. Also, physicians need to monitor for complications such as fistula formation between the pancreas and surrounding structures in the setting of chronic inflammation due to recurrent episodes of pancreatitis. Early identification of a fistula is important for surgical planning. Furthermore, since recent studies suggested a higher incidence of additional primary malignancies in patients with IPMN of the pancreas compared to the general population, patients may be considered for screening for other primary malignancies.

RESUMEN

BACKGROUND: Increased enthusiasm toward newer fashion trends among rural India along with the lack of government regulation has led to increased tattoo reactions. OBJECTIVE: The objective of this study is to describe various clinical manifestations of hypersensitive reactions to tattoo ink reported at a tertiary care hospital in Mandya district. MATERIALS AND METHODS: An observational study was carried out over a period of 1 year from June 2014 to May 2015 at Mandya Institute of Medical Sciences, Mandya. All the patients reporting with allergic reaction due to tattooing were included in the present study after obtaining informed consent. Transient acute inflammatory reaction, infections, and skin diseases localized on tattooed area were excluded from this study. A detailed history regarding the onset, duration and color used for tattooing were collected. Cutaneous examination and biopsy was to done to know the type of reaction. RESULTS: Fifty cutaneous allergic reactions were diagnosed among 39 patients. Mean age of subjects was 22 years and mean duration before the appearance of lesion was 7 months. Common colors associated with reactions were red (53.9%), black (33.3%), green (5.1%), and multicolor (7.7%). Itching was the predominant symptom. Skin lesions mainly consisted of lichenoid papules and plaques, eczematous lesions, and verrucous lesions. Lichenoid histopathology reaction was the most common tissue allergic reaction. CONCLUSION: Increasing popularity of tattooing among young people has predisposed to parallel increase in adverse reactions. Red pigment is most common cause of allergic reaction in the present study, and lichenoid reaction is the most common reaction.
