RESUMEN

Degradation of ibuprofen, one of the most consumed drugs globally, by a mixed bacterial consortium was investigated. A contaminated hospital soil was used to enrich a bacterial consortium possessing the ability to degrade 4 mg/L ibuprofen in 6 days, fed on 6 mM acetate as a supplementary carbon source. Maximum ibuprofen degradation achieved was 99.51%, and for optimum ibuprofen degradation modelled statistically, the initial ibuprofen concentration, and temperature were determined to be 0.515 mg/L and 35 °C, respectively. The bacterial community analyses demonstrated an enrichment of Pseudomonas, Achromobacter, Bacillus, and Enterococcus in the presence of ibuprofen, suggesting their probable association with the biodegradation process. The biodegradation pathway developed using open-source metabolite predictors, GLORYx and BioTransformer suggested multiple degradation routes. Hydroxylation and oxidation were found to be the major mechanisms in ibuprofen degradation. Mono-hydroxylated metabolites were identified as well as predicted by the bioinformatics-based packages. Oxidation, dehydrogenation, super-hydroxylation, and hydrolysis were some other identified mechanisms.

RESUMEN

PURPOSE OF THE STUDY Although there are numerous studies on outcomes and comparison of open and closed reduction but there is no clarity on relationship between outcomes and complications with type of surgical intervention done for Type 3 Gartland supracondylar humerus fracture. The aim of this study is to compare the outcomes and complications of closed vs open reduction in Type 3 Gartland supracondylar humerus fractures. MATERIAL AND METHODS Electronic literature searches of Embase, MEDLINE and the Cochrane Library was conducted in February 2022 using the terms "supracondylar", "humerus", "fracture", "Gartland type 3" and synonymous. The data extracted included the study details, demographic data, procedure performed, final functional and cosmetic outcome according to Flynn criteria and complications of included studies. RESULTS Pooled data analysis revealed no significant difference in mean satisfactory outcome rate according to Flynn cosmetic criteria in open group (97%, 95% CI 95.5%-98.5%), as compared to closed group (97.5%, 95% CI 96.3%-98.7%), although a statistically significant difference in mean satisfactory rate according to Flynn functional criteria in open group (93.4%, 95% CI 90.8%- 96.1%) as compared to closed group (98.5%, 95% CI 97.5%-99.4%) was noted. On separate comparison of the two-arm studies, closed reduction favoured better functional outcomes (RR 0.92, 95% CI 0.86-0.99). CONCLUSIONS Closed reduction and percutaneous fixation have better functional outcome than open reduction with K-wire fixation. But there was no significant difference in cosmetic outcomes, overall complication rate and nerve injury with either open or closed reduction. The threshold of converting a closed reduction to an open reduction in supracondylar humerus fractures of children should be high. Key words: supracondylar humerus, open reduction, percutaneous pinning, Flynn criteria.

RESUMEN

Bilayer tablets offer various drug release profiles for individual drugs incorporated in each layer of a bilayer tablet, which is rarely achievable by conventional tablets. These tablets also help avoid physicochemical incompatibilities between drugs and excipients. Successful manufacturing of such more complex dosage forms depends upon screening of material attributes of API and excipients as well as optimization of processing parameters of individual unit operations of the manufacturing process that must be strictly monitored and controlled to obtain an acceptable drug product quality and performance in order to achieve safety and efficacy per regulatory requirements. Optimizing formulation attributes and manufacturing processes during critical stages, such as blending, granulation, pre-compression, and main compression, can help avoid problems such as weight variation, segregation, and delamination of individual layers, which are frequently faced during the production of bilayer tablets. The main objective of this review is to establish the basis for the implementation of Quality by Design (QbD) system principles for the design and development of bilayer tablets, encompassing the preliminary and systematic risk assessment of critical material attributes (CMAs) and critical process parameters (CPPs) with respect to in-process and finished product critical quality attributes (CQAs). Moreover, the applicability of the QbD methodology based on its purpose is discussed and complemented with examples of bilayer tablet technology.

RESUMEN

OBJECTIVE: Myxedema crisis (MC) is a rare condition. There is a dearth of data regarding the predictors of mortality in MC. Predictive scores for mortality specific to the clinical and biochemical profile of MC are still lacking. DESIGN AND METHODS: All consecutive patients presenting with MC from September 2006 to December 2020 comprised the new cohort. Patients managed between January 1999 and August 2006 comprised the old cohort. Both cohorts were compared for the determination of secular trends. Combined analysis of both the cohorts was done for clinico-demographic profile and predictors of mortality. Myxedema score (MS) and qSOFA (Quick Sequential Organ Failure Assessment) score were evaluated in all the patients. RESULTS: A total of forty-one patients (new cohort; n = 18 and old cohort; n = 23) were enrolled into the study. There was a female predominance (80.5%). Nearly half (51.2%) of the patients were newly diagnosed with hypothyroidism on admission. Overall mortality was 60.9%. On comparative analysis among survivors and non-survivors, female gender (OR 20.4, p value 0.018), need for mechanical ventilation (OR16.4, p value 0.009), in-hospital hypotension (OR 9.1, p value 0.020), and high qSOFA score (OR 7.1, p value 0.023) predicted mortality. MS of > 90 had significantly higher mortality (OR-11.8, p value - 0.026) while MS of > 110 had 100% mortality. There was no change in secular trends over last 20 years. There was no difference in outcome of patients receiving oral or IV levothyroxine. CONCLUSION: Myxedema crisis is associated with high mortality despite improvement in health care services. The current study is first to elucidate the role of the MS in predicting mortality in patients with MC.

RESUMEN

BACKGROUND: Etiological diagnosis of delayed puberty is difficult. Despite availability of various basal and stimulation tests differentiation between constitutional delay in puberty and hypogonadotropic hypogonadism is still challenging. OBJECTIVE: To elucidate the role of GnRH agonist-stimulated inhibin B (GnRH-iB) for the differential diagnosis of delayed puberty. STUDY DESIGN: Participants were recruited into "exploratory cohort" (n = 39) and "validation cohort" (n = 16). "Exploratory cohort" included children with spontaneous puberty and patients with hypogonadotropic hypogonadism. "Validation cohort" constituted children who presented with delayed puberty. INTERVENTION AND OUTCOME: GnRHa (Triptorelin) stimulation test along with measurement of inhibin B level at 24 h after GnRHa injection was performed in all the study participants. Cut-offs for GnRH-iB were derived from the "exploratory cohort". These cut-offs were applied to the "validation cohort". Basal LH, basal inhibin B(INH-B), GnRHa-stimulated LH at 4 h (GnRH-LH) and GnRH-iB were evaluated for the prediction of onset of puberty on prospective follow-up. RESULTS: GnRH-iB at a cut-off value of 113.5 pg/ml in boys and 72.6 pg/ml in girls had 100% sensitivity and specificity for the documentation of puberty. In the "validation cohort" basal LH, basal INH-B, GnRH-LH, and GnRH-iB had a diagnostic accuracy of 68.75%, 81.25%, 68.75% and 93.75% respectively, for the prediction of onset of puberty. Basal LH, basal INH-B and GnRH-LH used alone or in combination were inferior to GnRH-iB used alone. CONCLUSION: GnRHa-stimulated inhibin B (GnRH-iB) is a convenient and easily employable test for the differentiation of constitutional delay in puberty from hypogonadotropic hypogonadism.

RESUMEN

INTRODUCTION:  Hyperlipidemia is a disorder in which lipid and cholesterol levels in the blood are elevated. Diabetes, coronary heart disease, obesity, and hypertension are commonly linked to hyperlipidemia. Despite this, hyperlipidemia is a widely neglected illness, owing to its asymptomatic nature, ignorance of aberrant lipid profiles on screening, and economic issues in poor countries such as India. Platelets have been shown to have a role in the thrombus consequences of atheromatous damage in hyperlipidemic individuals by initiating and propagating atherosclerotic plaques. Platelets with bigger diameters are thought to be more metabolically, enzymatically, and functionally agile than platelets with lower sizes. In steady-state operation, these bigger platelets release more thromboxane B2 than regular platelets. Platelets with bigger sizes are more hemostatically active and hence have a higher chance of forming a thrombus and thromboembolism. The aim of this study was to compare the values of key platelet parameters and platelet function in hyperlipidemic patients with normal age and sex-matched controls. MATERIAL AND METHODS:  A total of 100 individuals were included in this study, with 68 cases of hyperlipidemia and 32 controls having normal lipid profiles. Platelet volume indices (PVI) such as platelet count (PC), mean platelet volume (MPV), platelet distribution width (PDW), platelet large cell ratio (P-LCR), plateletcrit (PCT), and platelet function (platelet aggregation with adenosine diphosphate, ADP) were compared between hyperlipidemia patients and age sex-matched controls with normal lipid profiles. RESULTS:  The cases had a statistically significant higher mean MPV (10.55 ± 1.81), PDW (14.93 ± 2.82), and P-LCR (30.97 ± 11.74) compared to mean MPV (9.35 ± 1.85), PDW (13.10 ± 2.60), and P-LCR (25.13 ± 12.23) of controls (p-value < 0.05). No significant difference was observed between the study group and control group with respect to mean PC and PCT (p-value > 0.05). In this study, there was a statistically significant increase noted in platelet aggregation percentage in hyperlipidemic patients than in the control group (42.03 ± 25.28 vs 31.25 ± 15.11) (p-value < 0.05). CONCLUSION:  To conclude, platelet parameters are a significant, easy, and cost-effective method for predicting future acute episodes in hyperlipidemic patients that should be utilized more widely. To avoid vascular events, these individuals may require higher antiplatelet dosages and more rigorous hyperlipidemia therapy.

RESUMEN

As diabetes is on the rise worldwide, early screening and detection of its complications is crucial. The first clinical sign of renal dysfunction in diabetes is microalbuminuria. Ferritin may have a possible role in the development and prediction of microalbuminuria and other complications of diabetes by 3 possible mechanisms- 1) it is a marker of elevated body iron stores. 2) acts as acute-phase reactant and elevation reflects inflammation 3) Delayed clearance of glycosylated ferritin in patients with diabetes causes raised ferritin levels. In this premise, we studied the association between serum ferritin levels and microalbuminuria, glycemic control and dyslipidemia in type 2 diabetic patients. MATERIAL: A cross-sectional study was carried out at a tertiary hospital in northern India involving 152 patients of type 2 diabetes mellitus. Anthropometric measurements (weight, height), sample collection for basic laboratory parameters including complete blood count, kidney function tests, liver function tests, HbA1c, lipid profile, serum iron and ferritin levels, urinary albumin- creatinine ratio was done. A fundus examination was performed. Results were analyzed using descriptive statistics and making comparisons among various groups. Categorical data were summarized as proportions or percentages while discrete as mean. Chi-square test was used for testing associations. OBSERVATION: Mean serum ferritin levels were significantly higher in patients having microalbuminuria as against patients having normal urinary albumin- creatinine ratio (539 vs 292, p-value- 0.04). Patients having poor glycemic control (HbA1c > 7) had higher ferritin levels (p-value- 0.024). There was a near-significant association (p-value-0.06) between serum ferritin and triglyceride levels. More cases with raised serum ferritin had higher triglyceride levels. Patients having microalbuminuria had a higher prevalence of diabetic retinopathy (p-value- 0.003) and higher triglyceride levels (p-value- 0.041). CONCLUSION: Ferritin can act as a marker of diabetic nephropathy, poor glycemic control and dyslipidemia in type 2 diabetic patients. Our study, therefore, indicates that programs to prevent complications of diabetes would be more effective by placing greater emphasis on patients having higher ferritin levels.

RESUMEN

Dual antiplatelet treatment (DAPT) is the cornerstone of the management and prophylaxis of acute coronary syndrome (ACS). However, the associated risk of bleeding with the usage of DAPT and risk of thrombosis with stoppage of the drug makes it a challenging task to take appropriate decisions regarding the choice and duration of DAPT. The present study is aimed to tackle these challenges and to analyze whether prolonged dual antiplatelet therapy carries more risk of bleeding or a higher risk of thrombosis is present with discontinuation of the same. MATERIAL: In this study, a total of 235 cases of confirmed myocardial infarction, unstable angina, or those who underwent percutaneous intervention were included. After 1 year, the number of patients on DAPT, the type of antiplatelets they were using were observed, their ischemic risk was calculated using DAPT score, and bleeding risk was calculated using PRECISE-DAPT score. Bleeding events were assessed using BARC classification. OBSERVATION: Out of 235 patients, the majority of the patients were males (78.7%). Only 7.2% of the patients had bleeding since the start of the drugs. The majority (5% out of 7.2%) of bleeding episodes were clinically insignificant. 163 (69%) patients were on Dual antiplatelet therapy after 1 year. Out of which 115 were appropriately taking DAPT as per their DAPT score. Patients with high bleeding risk (PRECISE DAPT score ≥25) were 89, out of which 38 (53.2%) patients were taking SAPT, appropriate for their bleeding risk. While 112 (68.7%) were taking prolonged DAPT, appropriate for PRECISE-DAPT risk. CONCLUSION: The majority of patients remained on DAPT following discharge for more than 1 year after ACS. This suggests that treating physicians prioritizes ischemic risk reduction over bleeding risk in patients with ACS, according to the patient's risk profile.

RESUMEN

BACKGROUND: Men who have sex with men (MSM) are at high risk of acquiring sexually transmitted illnesses. The gross stigmatization of homosexuality and discrimination has always affected their health-seeking behavior. OBJECTIVES: The study aimed to assess the magnitude of sexual health problems, factors associated, and their health-seeking behavior. METHODS: Descriptive cross-sectional study was conducted in Agra city, Uttar Pradesh during December 2017 and November 2019 among a sample of 52 MSM. The Snowball technique of sampling was used to recruit the eligible subjects. Data were collected by interview and analyzed using MS excel. RESULTS: Overall prevalence of any sexual health problem in past 1 year was 71.2%. Anal/perianal problems (26.9%) and genital/oral vesicles (26.9%) were the most commonly encountered illnesses MSM who had all their sexual encounters with men (completely homosexual), those MSM who used to play both insertive and receptive roles, had 5 or more sexual partners, used condom irregularly had significantly higher chances of having sexual health problems. Most (70.3%) MSM sought treatment for their sexual health problem from an Allopathic doctor; 29.4% took treatment from a government health facility. The majority (94.1%) of them were reportedly satisfied with the health care facility. Most (79.4%) respondents preferred not to disclose their sexual behavior during interaction with their sexual health care provider. CONCLUSION: High prevalence of sexual health problems was found among MSM who engage in high-risk sexual behavior. MSM requires access to STIs screening. Behavior change communication is needed to improve their health-seeking behavior.

RESUMEN

Background The electrical activities of heart recorded as electrocardiogram (ECG) are mostly done in supine postures. The body postural changes have effects in these electrical activities in heart which needs to be properly recognized. Objective To find the variations in electrocardiogram during postural changes from supine to upright i.e. sitting and standing postures among apparently healthy young adults. Method A cross sectional study was carried out in Manipal College of Medical Sciences after the institutional ethical clearance. The apparently healthy 30 Nepalese male medical students between 18-25 years of age were enrolled. The electrocardiography was elicited in supine, sitting and standing postures in the participants after 5 minutes' interval between each procedure in each participant. Result The highest mean amplitudes of Q wave were seen in sitting postures (0.12±0.04 mm), R wave in standing postures (1.46±0.55 mm) and S wave also in standing postures (0.23±0.2 mm). The mean amplitudes of Q and S waves showed statistically significant difference when compared between supine and upright postures. The maximum QRS duration was found while sitting (0.08±0.01 ms)and maximum heart rate in standing posture (82.43±10.59/min). The mean comparison of heart rate was statistically highly significant when compared between supine and standing postures. The mean QRS frontal axis was comparatively increased while standing (64.30±39.29). Conclusion The electrical activities of heart vary during postural changes among apparently healthy young adults. These changes are most prominent when compared between supine and standing postures which urges for careful interpretation of electrocardiogram if it is done in upright postures.

RESUMEN

We theoretically predict and experimentally demonstrate a nonthermal pathway to optically enhance superexchange interaction energies in a material based on exciting ligand-to-metal charge-transfer transitions, which introduces lower-order virtual hopping contributions that are absent in the ground state. We demonstrate this effect in the layered ferromagnetic insulator CrSiTe_{3} by exciting Te-to-Cr charge-transfer transitions using ultrashort laser pulses and detecting coherent phonon oscillations that are impulsively generated by superexchange enhancement via magneto-elastic coupling. This mechanism kicks in below the temperature scale where short-range in-plane spin correlations begin to develop and disappears when the excitation energy is tuned away from the charge-transfer resonance, consistent with our predictions.

RESUMEN

BACKGROUND: Hypoxemia-induced endothelial dysfunction leads to microalbuminuria. Microalbuminuria (MAB) has also been used as a parameter to assess the risk of cardiovascular events in an individual. The aim of this study was to observe the relationship of MAB in patients with chronic obstructive pulmonary disease (COPD) and to correlate MAB with different stages of COPD. MATERIALS AND METHODS: This cross sectional study included 140 patients with COPD selected according to GOLD guidelines based on COPD test assessment score and the number of exacerbations who had smoking pack years of more than 10 years. Urine albumin creatinine ratio (UACR) more than 30 mg/gm represents MAB. RESULTS: The UACR increases as the severity of groups of COPD increases with significant differences in UACR values among different COPD groups. Significant differences were seen among various groups of COPD when compared for different clinical parameters such as SPO2, PaO2, PaCO2, pH, and C-reactive protein (CRP). Pearson correlation analysis revealed that UACR was significantly inversely related with PaO2 (r = -0.514, P < 0.001), SPO2 (r = -0.397, P < 0.001) and FEV1 (r = -0.441, P < 0.001) and it was significantly positively correlated with PaCO2 (r = 0.675, P < 0.001). CONCLUSION: This study indicates that there is strong relationship of MAB in patients with COPD and the levels of MAB increase as the severity of COPD increases due to hypoxia and endothelial dysfunction. As MAB is a marker for cardiovascular risk, patients with COPD can be routinely evaluated for the urine test of MAB specially who are at increased risk for cardiovascular events.

RESUMEN

OBJECTIVES: To find out the relative prevalence of fetal neural tube defect (NTD) and its outcome in terms of survival at birth and beyond 2 years of age. METHODS: A 10-year prospective (2008-2018) observational study was performed, which included all prenatally detected fetal NTD. Two-year follow-up was done in cases of pregnancies resulting in live birth, in terms of their survival, physical morbidity and developmental delay. RESULTS: NTD was seen in 401/648 (62%) cases among the central nervous system malformations. More than half of the cases (54.1%) presented after 20 weeks of gestation, and 42.8% of the mothers were primiparous. Spina bifida was seen in 206 cases, anencephaly in 144, encephalocele in 43, whereas iniencephaly was seen in only eight cases. Associated anomalies were present in 51.2%. Only 19.0% cases were live-born, and merely 11% were alive beyond 2 years of age. Among types of spina bifida, lumbosacral meningomyocele was the most common (41.6%), whereas thoracic was the rarest (8.7%). After 2 years, physical disability was observed in more than half of the cases who survived. CONCLUSIONS: NTD is one of the commonest malformations with high mortality, and the physical and mental sub-normality is high among those who survive.

RESUMEN

Microinvasive oral squamous cell carcinoma (MIOSCC) is an early stage malignant tumour,showing invasion of the epithelial cells confined to the superficial lamina propria. This is matter of debate in respect to the clinical presentation, metastasis, therapeutic intervention and prognosis. A 32-year female reported to the department with chief complaint of wound and burning sensation in her left back region of lower gums. Clinical diagnosis of erosive oral lichen planus was made and topical steroid was started. The lesion clinically healed with the use of topical medicine. After stopping the medication the lesion recurred, following which, excisional biopsy was done. On histopathological evaluation diagnosis of microinvasive oral squamous cell carcinoma was made. Recurrence of similar symptom in the same site was seen 10 weeks later, which now showed features of moderate dysplasia. Clinical features of microinvasive oral squamous cell carcinoma resembles premalignant lesion, leading to difficulty in diagnosis, treatment and prognostic assessment. Thus, adequate representation of this entity is necessary.

RESUMEN

Most soft-tissue lumps in the hand are benign, with ganglions being the commonest, but in the thenar region, solid soft-tissue masses are more common than a ganglion. In this review, we focus on soft-tissue lesions (neoplastic and non-neoplastic) presenting as a palpable lump in this region. A specific diagnosis can often be reached using ultrasonography and/or magnetic resonance imaging. Most of these lesions are managed in local hospitals or primary care, whereas some are referred to specialist centres. This review article will help both general and musculoskeletal radiologists to diagnose and characterise these lesions, provide a guide for further imaging, and provide an insight into imaging features that may need specific investigations such as core biopsy, tertiary referral, and further review at multidisciplinary meetings.

RESUMEN

BACKGROUND: Chronic kidney disease (CKD) predisposes to accelerated atherosclerosis that is measured by carotid artery intima media thickness (CIMT) and brachial artery flow-mediated dilation (FMD). The aim of this study was to assess the noninvasive risk markers of subclinical atherosclerosis and endothelial dysfunction and their correlation with disease severity. METHODS AND RESULTS: This was a cross-sectional study conducted in 62 patients with CKD: 38 predialysis and 24 on hemodialysis and 50 age- and gender-matched controls. In both the patients and controls, high-sensitivity C-reactive protein (CRP) levels, %FMD, and CIMT were measured. Patients with CKD had increased CRP levels {[5.8 (1.0-6.0)] mg/L vs [1.0 (0.5-2.20)] mg/L; P < 0.001}; %FMD was significantly lower in patients on hemodialysis (5.51%) compared with stage IV (7.62%) and stage III (15.02%) and 17.95% in control subjects (P < 0.001); and CIMT values in hemodialysis patients (0.88 ± 0.06 mm) were significantly higher compared with stage IV (0.67 ± 0.10) and stage III (0.61 ± 0.12) (P < 0.001). Increased CIMT values were seen in patients with CKD (0.82 ± 0.21 mm) than in the healthy controls (0.55 ± 0.16 mm). In patients with CKD, a significant negative correlation was found between CRP levels and FMD responses (r = -0.315; P < 0.001), while a significant positive correlation was found between CRP and CIMT values (r = 0.327; P < 0.001). Compared with predialysis, hemodialysis subjects had significantly lower FMD and higher CRP and IMT values. CONCLUSION: CKD confers a higher inflammatory status when compared with apparently healthy general population. Abnormal FMD responses and CIMT values are more commonly found in dialysis patients. Our findings suggest that CIMT and FMD can be used as noninvasive markers for early risk assessment and stratification in various stages of CKD.

RESUMEN

Dengue is a growing public health problem in India, and acute kidney injury (AKI) is one of the least studied complications of dengue virus infection (DVI). This study was conducted to investigate the incidence, clinical characteristics, and risk factors for AKI in DVI. This was a retrospective study of patients with confirmed DVI presenting as dengue fever (DF) or dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS) at our center over a period of 2 years. A total of 620 subjects fulfilling inclusion criteria were studied. Patients were divided into two cohorts (90 patients with AKI and 530 patients without AKI) to determine independent predictors of AKI. Among 620 patients, 454 (73.22%) had classical DF, 141 (22.74%) patients had DHF, and 25 (4.03%) patients had DSS. AKI was present in 90 (16.36%) patients; approximately one-third (31, 34.45%) had AKIN stage 1, 33 (36.66%) patients had AKIN stage 2, and 26 (28.88%) had AKIN stage 3. Among those with AKI, 14 patients expired and all had DHF/DSS. On multivariate logistic regression, AKI was associated with male gender [odds ratio (OR): 2.9], DHF (OR: 7.9), rhabdomyolysis (OR: 8.2), multiple-organ dysfunction (OR: 18.2), hypertension (OR: 0.7), diabetes mellitus (OR: 4.8), delayed hospitalization (OR: 2.2), and use of nephrotoxic drugs (OR: 2.86). In all, 320 patients (51.61%) had hospital stay >3 days. We found that AKI was an independent predictor for longer duration of hospital stay (OR: 7.2, 95% confidence interval: 4.8-10.7). AKI in DVI is associated with significant morbidity, mortality and longer hospital stay.

RESUMEN

BACKGROUND & AIMS: Vedolizumab is an anti-a4b7 monoclonal antibody that is licensed for the treatment of moderate to severe Crohn's disease and ulcerative colitis. The aims of this study were to establish the real-world effectiveness and safety of vedolizumab for the treatment of inflammatory bowel disease. METHODS: This was a retrospective study involving seven NHS health boards in Scotland between June 2015 and November 2017. Inclusion criteria included: a diagnosis of ulcerative colitis or Crohn's disease with objective evidence of active inflammation at baseline (Harvey-Bradshaw Index[HBI] ≥5/Partial Mayo ≥2 plus C-reactive protein [CRP] >5 mg/L or faecal calprotectin ≥250 µg/g or inflammation on endoscopy/magnetic resonance imaging [MRI]); completion of induction; and at least one clinical follow-up by 12 months. Kaplan-Meier survival analysis was used to establish 12-month cumulative rates of clinical remission, mucosal healing, and deep remission [clinical remission plus mucosal healing]. Rates of serious adverse events were described quantitatively. RESULTS: Our cohort consisted of 180 patients with ulcerative colitis and 260 with Crohn's disease. Combined median follow-up was 52 weeks (interquartile range [IQR] 26-52 weeks). In ulcerative colitis, 12-month cumulative rates of clinical remission, mucosal healing, and deep remission were 57.4%, 47.3%, and 38.5%, respectively. In Crohn's disease, 12-month cumulative rates of clinical remission, mucosal healing, and deep remission were 58.4%, 38.9%, and 28.3% respectively. The serious adverse event rate was 15.6 per 100 patient-years of follow-up. CONCLUSIONS: Vedolizumab is a safe and effective treatment for achieving both clinical remission and mucosal healing in ulcerative colitis and Crohn's disease.

RESUMEN

OBJECTIVE: This study investigated the effects of soapnut (Sapindus mukorossi) shell powder (SSP) on serum hormone level, egg quality, semen characteristics and reproductive performance of broiler breeders fed with a maize-soybean meal based diet. METHODS: Ninety six female and twenty four male CARIBRO-VISHAL broiler breeders, 38-week old, were individually caged and randomly allocated to four treatment groups (24 female breeders/treatment and 6 male breeders/treatment): an un-supplemented control (T1) and three groups with 0.0176% SSP (group T2), 0.026% SSP (group T3) and 0.0528% SSP (group T4), to have supplementary saponin at 0, 50, 75, and 150 ppm, respectively, for 42 days. RESULTS: The results indicated that serum (p<0.001) and seminal plasma (p<0.05) testosterone level, semen volume (p<0.001), mass motility (p<0.001), and live spermatozoa count (p<0.001) was increased in groups T3 and T4 compared to T2 and control groups. Compared with control group, total sperm count was increased (p<0.001) and dead spermatozoa count was decreased (p<0.001) in SSP supplemented groups. Supplementation of SSP did not affected the quality of egg lay. Compared with control group, fertility (p<0.01) and hatchability (total eggs set and fertile eggs set) (p<0.001) were significantly improved in SSP supplemented groups with the highest improvement in T3 treatment group. Embryonic death was decreased (p< 0.001) in SSP supplemented groups compared to control; lowest embryonic death was recorded in T3 treatment group. CONCLUSION: Thus, it was concluded that dietary supplementation of 0.026% SSP (saponin equivalent 75 ppm) improved the reproductive performance of broiler breeders.
