Bariatric Surgery and the Long-Term Risk of Venous Thromboembolism: A Population-Based Cohort Study.

PURPOSE: Bariatric surgery is associated with a greater venous thromboembolism (VTE) risk in the weeks following surgery, but the long-term risk of VTE is incompletely characterized. We evaluated bariatric surgery in relation to long-term VTE risk. MATERIALS AND METHODS: This population-based retrospective matched cohort study within three United States-based integrated health care systems included adults with body mass index (BMI) ≥ 35 kg/m2 who underwent bariatric surgery between January 2005 and September 2015 (n = 30,171), matched to nonsurgical patients on site, age, sex, BMI, diabetes, insulin use, race/ethnicity, comorbidity score, and health care utilization (n = 218,961). Follow-up for incident VTE ended September 2015 (median 9.3, max 10.7 years). RESULTS: Our population included 30,171 bariatric surgery patients and 218,961 controls; we identified 4068 VTE events. At 30 days post-index date, bariatric surgery was associated with a fivefold greater VTE risk (HRadj = 5.01; 95% CI = 4.14, 6.05) and a nearly fourfold greater PE risk (HRadj = 3.93; 95% CI = 2.87, 5.38) than no bariatric surgery. At 1 year post-index date, bariatric surgery was associated with a 48% lower VTE risk and a 70% lower PE risk (HRadj = 0.52; 95% CI = 0.41, 0.66 and HRadj = 0.30; 95% CI = 0.21, 0.44, respectively). At 5 years post-index date, lower VTE risks persisted, with bariatric surgery associated with a 41% lower VTE risk and a 55% lower PE risk (HRadj = 0.59; 95% CI = 0.48, 0.73 and HRadj = 0.45; 95% CI = 0.32, 0.64, respectively). CONCLUSION: Although in the short-term bariatric surgery is associated with a greater VTE risk, in the long-term, it is associated with a substantially lower risk.

Tuberculosis in pregnancy and adverse neonatal outcomes in two peruvian hospitals.

Background: According to the World Health Organization, tuberculosis (TB) ranks among the top 10 causes of death worldwide. The significance of TB during pregnancy lies in its symptoms, which can be mistaken for physiological changes associated with pregnancy. This confusion can lead to maternal-perinatal complications. Objective: To evaluate the association between pulmonary TB in pregnancy and adverse neonatal outcomes in two Peruvian hospitals. Methods: This is a retrospective cohort study. The target population consisted of pregnant women with and without pulmonary TB whose deliveries were attended at two public hospitals, located in Lima, Peru. The adverse neonatal outcomes were prematurity, low birth weight (LBW), and being small for gestational age (SGA). Crude and adjusted relative risks (RRa) were calculated with their respective 95% confidence intervals (95%CI). Results: Information from 212 patients was analyzed; 48.1% had TB during pregnancy, and 23.1% had adverse neonatal outcomes (8%, 11.3%, and 12.3% for LBW, prematurity, and SGA, respectively). In the adjusted model, pregnant women with pulmonary TB had a 3.52 times higher risk of having a newborn with at least one of the adverse outcomes than those who were not exposed (aRR, 3.52; 95%CI: 1.93-6.68). Conclusion: Pulmonary TB in pregnancy was jointly and independently associated with adverse neonatal outcomes, including LBW, prematurity, and being SGA.

Long-Term Outcomes of Medical Management vs Bariatric Surgery in Type 2 Diabetes.

Importance: Randomized clinical trials of bariatric surgery have been limited in size, type of surgical procedure, and follow-up duration. Objective: To determine long-term glycemic control and safety of bariatric surgery compared with medical/lifestyle management of type 2 diabetes. Design, Setting, and Participants: ARMMS-T2D (Alliance of Randomized Trials of Medicine vs Metabolic Surgery in Type 2 Diabetes) is a pooled analysis from 4 US single-center randomized trials conducted between May 2007 and August 2013, with observational follow-up through July 2022. Intervention: Participants were originally randomized to undergo either medical/lifestyle management or 1 of the following 3 bariatric surgical procedures: Roux-en-Y gastric bypass, sleeve gastrectomy, or adjustable gastric banding. Main Outcome and Measures: The primary outcome was change in hemoglobin A1c (HbA1c) from baseline to 7 years for all participants. Data are reported for up to 12 years. Results: A total of 262 of 305 eligible participants (86%) enrolled in long-term follow-up for this pooled analysis. The mean (SD) age of participants was 49.9 (8.3) years, mean (SD) body mass index was 36.4 (3.5), 68.3% were women, 31% were Black, and 67.2% were White. During follow-up, 25% of participants randomized to undergo medical/lifestyle management underwent bariatric surgery. The median follow-up was 11 years. At 7 years, HbA1c decreased by 0.2% (95% CI, -0.5% to 0.2%), from a baseline of 8.2%, in the medical/lifestyle group and by 1.6% (95% CI, -1.8% to -1.3%), from a baseline of 8.7%, in the bariatric surgery group. The between-group difference was -1.4% (95% CI, -1.8% to -1.0%; P < .001) at 7 years and -1.1% (95% CI, -1.7% to -0.5%; P = .002) at 12 years. Fewer antidiabetes medications were used in the bariatric surgery group. Diabetes remission was greater after bariatric surgery (6.2% in the medical/lifestyle group vs 18.2% in the bariatric surgery group; P = .02) at 7 years and at 12 years (0.0% in the medical/lifestyle group vs 12.7% in the bariatric surgery group; P < .001). There were 4 deaths (2.2%), 2 in each group, and no differences in major cardiovascular adverse events. Anemia, fractures, and gastrointestinal adverse events were more common after bariatric surgery. Conclusion and Relevance: After 7 to 12 years of follow-up, individuals originally randomized to undergo bariatric surgery compared with medical/lifestyle intervention had superior glycemic control with less diabetes medication use and higher rates of diabetes remission.

Elimination of 15N-thymidine after oral administration in human infants.

BACKGROUND: We have developed a new clinical research approach for the quantification of cellular proliferation in human infants to address unanswered questions about tissue renewal and regeneration. The approach consists of oral 15N-thymidine administration to label cells in S-phase, followed by Multi-isotope Imaging Mass Spectrometry for detection of the incorporated label in cell nuclei. To establish the approach, we performed an observational study to examine uptake and elimination of 15N-thymidine. We compared at-home label administration with in-hospital administration in infants with tetralogy of Fallot, a form of congenital heart disease, and infants with heart failure. METHODS: We examined urine samples from 18 infants who received 15N-thymidine (50 mg/kg body weight) by mouth for five consecutive days. We used Isotope Ratio Mass Spectrometry to determine enrichment of 15N relative to 14N (%) in urine. RESULTS/FINDINGS: 15N-thymidine dose administration produced periodic rises of 15N enrichment in urine. Infants with tetralogy of Fallot had a 3.2-fold increase and infants with heart failure had a 4.3-fold increase in mean peak 15N enrichment over baseline. The mean 15N enrichment was not statistically different between the two patient populations (p = 0.103). The time to peak 15N enrichment in tetralogy of Fallot infants was 6.3 ± 1 hr and in infants with heart failure 7.5 ± 2 hr (mean ± SEM). The duration of significant 15N enrichment after a dose was 18.5 ± 1.7 hr in tetralogy of Fallot and in heart failure 18.2 ± 1.8 hr (mean ± SEM). The time to peak enrichment and duration of enrichment were also not statistically different (p = 0.617 and p = 0.887). CONCLUSIONS: The presented results support two conclusions of significance for future applications: (1) Demonstration that 15N-thymidine label administration at home is equivalent to in-hospital administration. (2) Two different types of heart disease show no differences in 15N-thymidine absorption and elimination. This enables the comparative analysis of cellular proliferation between different types of heart disease.

Long term outcomes of metabolic/bariatric surgery in adults.

The prevalence of obesity continues to rise around the world, driving up the need for effective and durable treatments. The field of metabolic/bariatric surgery has grown rapidly in the past 25 years, with observational studies and randomized controlled trials investigating a broad range of long term outcomes. Metabolic/bariatric surgery results in durable and significant weight loss and improvements in comorbid conditions, including type 2 diabetes. Observational studies show that metabolic/bariatric surgery is associated with a lower incidence of cardiovascular events, cancer, and death. Weight regain is a risk in a fraction of patients, and an association exists between metabolic/bariatric surgery and an increased risk of developing substance and alcohol use disorders, suicidal ideation/attempts, and accidental death. Patients need lifelong follow-up to help to reduce the risk of these complications and other nutritional deficiencies. Different surgical procedures have important differences in risks and benefits, and a clear need exists for more long term research about less invasive and emerging procedures. Recent guidelines for the treatment of obesity and metabolic conditions have been updated to reflect this growth in knowledge, with an expansion of eligibility criteria, particularly people with type 2 diabetes and a body mass index between 30.0 and 34.9.

Bending time: lessons from critical, community-engaged, liberatory research.

In this article, we use the framework of chronopolitics and racialized time to explore our experiences as professors of color at predominantly white institutions who strive to do emancipatory, community-driven research. Our shared work as organizers for Education for Liberation Minnesota (EdLibMN), a grassroots organization working to bring together various constituencies in Minnesota to organize for educational justice, led us to think together about chronopolitics as a framework to understand how our scholarly commitments to social transformation and liberatory education impact our labor and teaching practices at our institutions. This framework allows us to examine our relationships with communities in our individual research and advocacy contexts as well as in our shared work as organizers for EdLibMN. In particular, we explore how the urgency and timeline of our community-based advocacy work and the rhythms and improvisation of participatory action research are juxtaposed with the surveillance and evaluation of our labor and the urgency of "tenure clocks" at our institutions. We end by discussing our own transformational learning through our collaborations with community researchers and organizers. We speculate about the possibilities of bending time-the chronopolitics of collective struggle and joy-that allows us to focus on building relationships as a central tenet of emancipatory research practices and to ensure our own health and wellbeing as scholar-activists of color.

Association between early sexual initiation and sexually transmitted infections among Peruvian reproductive-age women.

Background: Sexually transmitted infections (STIs) are a serious public health problem worldwide, especially among reproductive-age women. The early sexual onset of sexual intercourse (EOSI) has been suggested as a risk factor, although there is no data at the national level. Objective: To evaluate the association between EOSI and STIs in Peruvian women of childbearing age. Methods: Analytical cross-sectional study with secondary data analyzes of the Peruvian Demographic and Family Health Survey 2018. The outcome was the presence of STIs in the last 12 months and the exposure variable was EOSI (age < 15 years at the time of their first sexual experience). To evaluate the association of interest, crude and adjusted prevalence ratios (aPRs) were calculated using generalized linear models with Poisson family and logarithmic link function. Results: We analyzed data from 31,028 women of childbearing age. The 11.3% reported having STIs in the last 12 months and 20.2% of the participants had an EOSI. After adjusting for potential confounders, we found that EOSI was associated with STIs (aPR: 1.27; 95% CI: 1.08-1.50; p = 0.005). When conducting stratified analysis by area of residence and number of sexual partners, this association was maintained in women living in urban areas (aPR: 1.36; 95% CI: 1.11-1.66; p = 0.003) those who did not report having a history of multiple sexual partners (aPR: 1.27; 95% CI: 1.08-1.51; p = 0.005), and those in the middle (aPR: 1.42; 95% CI: 1.03-1.97; p = 0.034) and highest (aPR: 2.12; 95% CI: 1.33-3.39; p = 0.002) wealth quintiles. Conclusion: Among reproductive-age women from Peru, EOSI was associated with STIs, especially in women living in urban areas, with no history of multiple sexual partners, and belonging to the middle to higher wealth index. The implementation of measures to prevent EOSI and fostering appropriate sexual health counseling for women with EOSI is advised.

Surrogates of Muscle Mass on Cardiac MRI Correlate with Exercise Capacity in Patients with Fontan Circulation.

BACKGROUND: Sarcopenia is an increasingly recognized marker of frailty in cardiac patients. Patients with a history of congenital heart disease and Fontan procedure have a higher risk of developing progressive muscle wasting. Our objective was to determine if we could use routine cardiac MRI (CMR) for the surveillance of muscle wasting. METHODS: A retrospective study of all Fontan patients (n = 75) was conducted at our institution, with CMR performed from 2010 to 2022 and exercise stress testing performed within 12 months (4.3 ± 4.2 months). The skeletal muscle area (SMA) for the posterior paraspinal and anterior thoracic muscles were traced and indexed for body surface area (BSA). Patients were stratified by percentile into the upper and lower quartiles, and the two groups were compared. Multivariable regression was performed to control for sex and age. RESULTS: There was a significant positive association of both anterior (r = 0.34, p = 0.039) and paraspinal (r = 0.43, p = 0.007) SMA to peak VO2. Similarly, paraspinal but not anterior SMA was negatively associated with the VE/VCO2 (r = -0.45, p = 0.006). The upper quartile group had significantly more males (18/19 vs. 8/20; p = 0.0003) and demonstrated a significantly higher peak VO2 (32.2 ± 8.5 vs. 23.8 ± 4.7, p = 0.009), a higher peak RER (1.2 ± 0.1 vs. 1.1 ± 0.04, p = 0.007), and a significantly lower VE/VCO2 (32.9 ± 3.6 vs. 40.2 ± 6.2, p = 0.006) compared to the lowest quartile. The association of SMA to VO2 peak and VE/VCO2 was redemonstrated after controlling for sex and age. CONCLUSION: Thoracic skeletal muscle area may be an effective surrogate of muscle mass and is correlated to several measures of cardiorespiratory fitness post-Fontan. CMR would be an effective tool for the surveillance of sarcopenia in post-Fontan patients given its accessibility and routine use in these patients.

Maternal and Neonatal Outcomes of Pregnancy within 7 years after Roux-Y Gastric Bypass or Sleeve Gastrectomy Surgery.

PURPOSE: Few studies examine whether maternal and neonatal outcomes differ by time from metabolic and bariatric surgery (MBS) to conception. We describe maternal and neonatal outcomes among women with pregnancy after Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) overall and by whether conception occurred during the period when pregnancy is not recommended (< 18 months postoperative) versus later. MATERIALS AND METHODS: A prospective cohort study enrolled 135 US adult women (median age, 30 years, body mass index [BMI], 47.2 kg/m2) who underwent RYGB or SG (2006-2009) and subsequently reported ≥ 1 pregnancy within 7 years. Participants self-reported pregnancy-related information annually. Differences in prevalence of maternal and neonatal outcomes by postoperative conception timeframe (< 18 versus ≥ 18 months) were assessed. RESULTS: Thirty-one women reported ≥ 2 postoperative pregnancies. At time of postoperative conception (median 26 [IQR:22-52] months postoperative) median BMI was 31 (IQR:27-36) kg/m2. Excessive gestational weight gain (55%), cesarean section (42%) and preterm labor or rupture of membranes (40%) were the most common maternal outcomes. Forty percent of neonates had a composite outcome of still birth (1%), preterm birth (26%), small for gestational age (11%), or neonatal intensive care unit admission (8%). Prevalence of outcomes did not statistically significantly differ by timeframe. CONCLUSION: In US women who conceived ≤ 7 years following RYGB or SG, 40% of neonates had the composite neonatal outcome. The prevalence of maternal and neonatal outcomes post-MBS were not statistically significant by conception timeframe.

A generic platform to couple affinity chromatography with native mass spectrometry for the analysis of therapeutic monoclonal antibodies.

Affinity chromatography coupled with native mass spectrometry has emerged as a powerful tool for the analysis of therapeutic monoclonal antibodies (mAbs). Exploiting the specific interactions between mAbs and their ligands, these methods not only provide orthogonal means to study the highly complex mAb attributes, but also offer insights on their biological relevance. Despite the great promise, application of affinity chromatography - native mass spectrometry in routine mAb characterization has been limited, largely due to the complicated experimental set up. In this study, we introduced a generic platform to facilitate the online coupling of different affinity separation modes with native mass spectrometry. Built upon a recently introduced native LC-MS platform, this new strategy can accommodate a wide range of chromatographic conditions, and therefore, allow greatly simplified experimental set up and facile swapping of affinity separation modes. The utility of this platform was demonstrated by successful online coupling of three affinity chromatography methods (protein A, FcγRIIIa, and FcRn) with native mass spectrometry. The developed protein A-MS method was tested both in a "bind-and-elute" mode for rapid mAb screening and in a high-resolution resolving mode to study mAb species with altered protein A affinity. The FcγRIIIa-MS method was applied to achieve glycoform-resolved analyses of both IgG1 and IgG4 subclass molecules. The FcRn-MS method was demonstrated in two case studies, where specific post-translational modifications and Fc mutations were known to alter FcRn affinities.

Reduction in Long-term Mortality After Sleeve Gastrectomy and Gastric Bypass Compared to Nonsurgical Patients With Severe Obesity.

OBJECTIVE: To separately compare the long-term risk of mortality among bariatric surgical patients undergoing either Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) to large, matched, population-based cohorts of patients with severe obesity who did not undergo surgery. BACKGROUND: Bariatric surgery has been associated with reduced long-term mortality compared to usual care for severe obesity which is particularly relevant in the COVID-19 era. Most prior studies involved the RYGB operation and there is less long-term data on the SG. METHODS: In this retrospective, matched cohort study, patients with a body mass index ≥35 kg/m 2 who underwent bariatric surgery from January 2005 to September 2015 in three integrated health systems in the United States were matched to nonsurgical patients on site, age, sex, body mass index, diabetes status, insulin use, race/ethnicity, combined Charlson/Elixhauser comorbidity score, and prior health care utilization, with follow-up through September 2015. Each procedure (RYGB, SG) was compared to its own control group and the two surgical procedures were not directly compared to each other. Multivariable-adjusted Cox regression analysis investigated time to all-cause mortality (primary outcome) comparing each of the bariatric procedures to usual care. Secondary outcomes separately examined the incidence of cardiovascular-related death, cancer related-death, and diabetes related-death. RESULTS: Among 13,900 SG, 17,258 RYGB, and 87,965 nonsurgical patients, the 5-year follow-up rate was 70.9%, 72.0%, and 64.5%, respectively. RYGB and SG were each associated with a significantly lower risk of all-cause mortality compared to nonsurgical patients at 5-years of follow-up (RYGB: HR = 0.43; 95% CI: 0.35,0.54; SG: HR = 0.28; 95% CI: 0.13,0.57) Similarly, RYGB was associated with a significantly lower 5-year risk of cardiovascular-(HR = 0.27; 95% CI: 0.20, 0.37), cancer- (HR = 0.54; 95% CI: 0.39, 0.76), and diabetes-related mortality (HR = 0.23; 95% CI:0.15, 0.36). There was not enough follow-up time to assess 5-year cause-specific mortality in SG patients, but at 3-years follow-up, there was significantly lower risk of cardiovascular- (HR = 0.33; 95% CI:0.19, 0.58), cancer- (HR = 0.26; 95% CI:0.11, 0.59), and diabetes-related (HR = 0.15; 95% CI:0.04, 0.53) mortality for SG patients. CONCLUSION: This study confirms and extends prior findings of an association with better survival following bariatric surgery in RYGB patients compared to controls and separately demonstrates that the SG operation also appears to be associated with lower mortality compared to matched control patients with severe obesity that received usual care. These results help to inform the tradeoffs between long-term benefits and risks of bariatric surgery.

A Prospective Cohort of Alcohol Use and Alcohol-related Problems Before and After Metabolic and Bariatric Surgery in Adolescents.

OBJECTIVE: To describe alcohol use, alcohol-related harm, and alcohol-related problems preoperatively and up to 8 years following metabolic and bariatric surgery (MBS) in adolescents. BACKGROUND: Risk for alcohol use and alcohol use disorders (AUD) increases post-Roux-en-Y gastric bypass and vertical sleeve gastrectomy in adults. However, data are lacking in adolescents who undergo MBS. METHODS: This study includes 217 adolescents (aged 13-19 y) enrolled in a 5-center prospective cohort study who underwent Roux-en-Y gastric bypass or vertical sleeve gastrectomy (2007-2011) and reported alcohol use preoperatively and annually postoperatively for up to 8 years. Time to elevated Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) score, alcohol-related harm, and alcohol-related problems were analyzed with Kaplan-Meier estimates of cumulative incidence. RESULTS: Preoperatively, the median age was 17 years; the median body mass index was 51 kg/m 2 . Alcohol use frequency and average quantity of drinks per drinking day increased postoperatively (2% consumed alcohol 2-4 times/month 6 months versus 24% 8 years postoperatively, P <0.001; 2% consumed≥3 drinks per drinking day 6 months versus 35% 8 years postoperatively, P <0.001). Cumulative incidence of postoperative onset elevated AUDIT-C score, alcohol-related harm, and alcohol-related problems at year 8 were 45% (95% CI:37-53), 43% (95% CI:36-51), and 47% (95% CI:40-55), respectively. CONCLUSIONS: Nearly half of those who underwent MBS as adolescents screened positively for AUD, symptoms of alcohol-related harm, or alcohol-related problems 8 years post-MBS, highlighting the risk for alcohol use and AUD after MBS in adolescents. AUD evaluation and treatment should be integrated into routine long-term care for adolescents undergoing MBS.

Gut adaptation after gastric bypass in humans reveals metabolically significant shift in fuel metabolism.

OBJECTIVE: Roux-en-Y gastric bypass surgery (RYGB) is among the most effective therapies for obesity and type 2 diabetes, and intestinal adaptation is a proposed mechanism for these effects. It was hypothesized that intestinal adaptation precedes and relates to metabolic improvement in humans after RYGB. METHODS: This was a prospective, longitudinal, first-in-human study of gene expression (GE) in the "Roux limb" (RL) collected surgically/endoscopically from 19 patients with and without diabetes. GE was determined by microarray across six postoperative months, including at an early postoperative (1 month ± 15 days) time point. RESULTS: RL GE demonstrated tissue remodeling and metabolic reprogramming, including increased glucose and amino acid use. RL GE signatures were established early, before maximal clinical response, and persisted. Distinct GE fingerprints predicted concurrent and future improvements in HbA1c and in weight. Human RL exhibited GE changes characterized by anabolic growth and shift in metabolic substrate use. Paradoxically, anabolic growth in RL appeared to contribute to the catabolic state elicited by RYGB. CONCLUSIONS: These data support a role for a direct effect of intestinal energy metabolism to contribute to the beneficial clinical effects of RYGB, suggesting that related pathways might be potential targets of therapeutic interest for patients with obesity with or without type 2 diabetes.

Industrial freezing and tempering for optimal functional properties in thawed Mozzarella cheese.

Mozzarella cheese was industrially frozen (-18 °C), stored for up to six months, tempered at 4 °C for one or three weeks and the structure and functionality compared to cheese stored at 4 °C and cheese aged at 4 °C for four weeks prior to freezing. When combined with ageing or tempering, the slow industrial freezing minimised changes to the protein network as detected by confocal microscopy and arrested proteolysis. Cheese functionality improved with three weeks of tempering, with properties similar to cheese refrigerated for one month, potentially due to increased proteolysis and protein rehydration. Frozen storage induced ß-sheet and ß-turn structures, as detected by S-FTIR microspectroscopy, with longer tempering leading to structural recovery in the cheese. This study indicates the proteolysis and functionality of frozen cheese can be optimised with tempering time. It also provides new insights into heat transfer during the industrial freezing and tempering of cheese.

Changes in nuclear pore numbers control nuclear import and stress response of mouse hearts.

Nuclear pores are essential for nuclear-cytoplasmic transport. Whether and how cells change nuclear pores to alter nuclear transport and cellular function is unknown. Here, we show that rat heart muscle cells (cardiomyocytes) undergo a 63% decrease in nuclear pore numbers during maturation, and this changes their responses to extracellular signals. The maturation-associated decline in nuclear pore numbers is associated with lower nuclear import of signaling proteins such as mitogen-activated protein kinase (MAPK). Experimental reduction of nuclear pore numbers decreased nuclear import of signaling proteins, resulting in decreased expression of immediate-early genes. In a mouse model of high blood pressure, reduction of nuclear pore numbers improved adverse heart remodeling and reduced progression to lethal heart failure. The decrease in nuclear pore numbers in cardiomyocyte maturation and resulting functional changes demonstrate how terminally differentiated cells permanently alter their handling of information flux across the nuclear envelope and, with that, their behavior.

INCIDENCE OF INFLAMMATORY BOWEL DISEASE: A SINGLE CENTRE RETROSPECTIVE STUDY.

BACKGROUND: Inflammatory bowel disease (IBD) is a chronic inflammatory disorder affecting the gastrointestinal tract. The etiology of this alarming condition is multifactorial. A Recently increasing trend in IBD is noted in our country. OBJECTIVE: The present study was designed with the main objective to assess the incidence and to identify the associated risk factors including demographic, geographical areas, and dietary patterns of IBD population of Northern of Karnataka viz. Hubli-Dharwad city. METHODS: A retrospective investigation was conducted on a cohort of 226 patients with a working diagnosis of IBD and those who were admitted between 2015 to 2019 the department of gastroenterology, SDMCMS&H. The diagnosis of IBD was made based on clinical, radiological, endoscopic, and histopathologic findings. The patients were categorized into IBD and those who have symptoms suggestive of IBD but did not fit into the diagnostic criteria into, non-IBD groups. The data about of on demography, diet patterns, and laboratory parameters were recorded. RESULTS: Among 226 patients enrolled in this study 2015-2019, IBD was confirmed in 54 Ulcerative colitis - 44 (19.46%), Crohn's disease - 10 (4.42%) patients with varying distribution of disease among different age groups and both genders, Ulcerative colitis (UC) [M: F: 28 (63.6%): 16 (36.4%)] and Crohn's disease (CD) [M: F: 07 (70.0%):03 (30.0%)]. Dietary pattern and other habitats had no significant contribution to illness and its symptoms. Urban (U) and Rural (R) divide was UC [U: R: 32 (72.7%): 12 (27.3%)], CD [U:R:07(70.0%):03(30.0%)] maintained. CONCLUSION: Incidence of IBD was high with UC as compared to CD. The incidence of IBD among patients presenting with symptoms suggestive of IBD is 19.46% with UC being major as compared to CD (4.42%). Male predominant patterns of IBD incidences were noted. Year by year increasing trend in disease burden was observed. The Dietary pattern has no direct correlation with IBD disease prevalence and incidences.

Os pacientes foram categorizados em DII e aqueles que apresentam sintomas sugestivos de DII, mas não se enquadraram nos critérios diagnósticos em grupos sem DII. Os dados sobre a demografia, padrões de dieta e parâmetros laboratoriais foram registrados. Resultados: Entre os 226 pacientes inscritos neste estudo entre 2015-2019, DII foi confirmada em 54 [RCUI - 44 (19,46%), DC - 10 (4,42%)] com distribuição variada da doença entre diferentes faixas etárias e ambos os sexos, colite ulcerativa (RCUI) [M: F: 28 (63,6%):16 (36,4%)] e doença de Crohn (DC) [M: F: 07 (70,0%): 03 (30,0%)]. O padrão alimentar e outros hábitos não tiveram contribuição significativa para a doença e seus sintomas. Urbanos (U) e rurais (R) dividiram-se em RCUI [U: R: 32 (72,7%):12 (27,3%)], DC [07 (70,0%): 03 (30,0%)]. Conclusão A incidência de DII foi elevada para RCUI em relação a DC. A incidência de DII entre os pacientes com sintomas sugestivos de DIB é de 19,46% com a RCUI sendo maior em relação a DC (4,42%). Foram observados padrões predominantes masculinos de incidência de DII. Ano a ano foi observada tendência crescente de carga da doença. O padrão dietético não tem correlação direta com a prevalência e incidências da DII.
