RESUMO
INTRODUCTION: Life-long adherence to gluten-free diet (GFD) and its assessment is essential for patients with celiac disease (CeD). We have developed and validated a tool for assessing adherence to GFD which can be used by both physicians and dietitians. METHODS: Phase 1: Development, content validation, and assessment of reliability of tool. Phase 2: Validation of tool against standard dietary evaluation (SDE) (gold standard), immunoglobulin A - anti-tissue transglutaminase antibodies (IgA anti-tTG Ab), and gluten immunogenic peptides in urine. Overall, 380 biopsy-confirmed patients with CeD (derivation cohort: n = 100 [phase 1], n = 210 [phase 2] and independent validation cohort, n = 70) were recruited. RESULTS: Of an initial 90-point questionnaire, 84 items (Celiac Disease: Compliance Assessment Test [CD-CAT.v1]) were retained after content validation and pilot testing. In phase 1, upon administering CD-CAT.v1 on 100 patients, a comprehensive 35-item tool (CD-CAT.v2; α = 0.86) was obtained after removing items with low test-retest reliability and item-rest correlation values. In phase 2, upon administering CD-CAT.v2 on 210 patients, 22 items were removed having low correlation values (R < 0.4) with SDE. Finally, a 13-item tool (CD-CAT.v3; α = 0.84) was obtained with high criterion validity with SDE ( r = 0.806, P < 0.001), moderate convergent validity with celiac disease adherence test ( r = 0.602, P = 0.007), and moderate to weak correlation with urine gluten immunogenic peptides ( r = 0.46, P = 0.001) and IgA anti-tTG Ab ( r = 0.39, P = 0.008), respectively. The final 13-item tool also strongly correlated with SDE ( r = 0.78, P < 0.001) in an independent validation cohort of 70 patients with CeD. Principal component analysis identified 3 relevant subscales with a cumulative variance of 62%. The sensitivity and specificity of CD-CAT.v3 were 80% and 91%, respectively, with an area under curve of 0.905 with SDE. The obtained cutoff score of <19 from the receiver operating characteristic curve was further categorized as 13 = excellent, 14-18 = very good, 19-28 = average, and >28 = poor adherence to GFD. DISCUSSION: CD-CAT is a new and rapid tool for monitoring dietary adherence to GFD with high sensitivity and specificity, which can be administered by both physicians and dietitians.
RESUMO
BACKGROUND AND AIM: Abnormalities in the reproductive functions are often ignored while evaluating a patient with celiac disease (CeD). We evaluated the entire reproductive functions in female patients with CeD. METHODS: In a case control study between 2020 and 2021 using detailed questionnaire, we evaluated reproductive functions (age at menarche, menstrual pattern, fertility, pregnancy outcome and menopause) in biopsy-proven female patients with CeD of age >10 years. The questionnaire was administered either in person or telephonically. Age-matched healthy female controls (twice the number) were also recruited. RESULTS: Of 1086 CeD patients, 470 were females and 288 were included. As compared with controls (n = 586), females with CeD had higher age at menarche (14.6 ± 2.0 vs 13.6 ± 1.5 years; P = 0.001), delayed menarche (30.8% vs 11.4%; P = 0.001), abnormal menstrual pattern (39.7% vs 25.8%; P < 0.001), involuntary delay in conception at > 1 year (33.8% vs 11.8%; P = 0.01), current infertility rate (10.5% vs 5.2%;P = 0.028), and poorer overall pregnancy outcomes (abortion [23.5% vs 12.8%; P = 0.001], pre-term birth [16.3% vs 3.7%; P = 0.001]). CONCLUSIONS: Either one or more aspect of reproductive functions and pregnancy outcome is affected adversely in three-fourth female patients with CeD.

BACKGROUND AND AIM: Celiac disease (CeD) has now become a global disease with a worldwide prevalence of 0.67%. Despite being a common disease, CeD is often not diagnosed and there is a significant delay in its diagnosis. We reviewed the impact of the delay in the diagnosis on the severity of manifestations of CeD. METHODS: We reviewed clinical records of 726 consecutive patients with CeD from the Celiac Clinic database and the National Celiac Disease Consortium database. We extracted specific data including the demographics, symptoms at presentation, time of onset of symptoms, time to diagnosis from the onset of the symptoms, and relevant clinical data including fold-rise in anti-tissue transglutaminase antibody (IgA anti-tTG Ab) and severity of villous and crypt abnormalities as assessed using modified Marsh classification. RESULTS: The median duration between the onset of symptoms and the diagnosis of CeD was 27 months (interquartile range 12-60 months). A longer delay in the diagnosis of CeD from the onset of symptoms was associated with lower height for age, lower hemoglobin, higher fold rise in IgA Anti tTG titers, and higher severity of villous and crypt abnormalities. About 18% of patients presented with predominantly non-gastrointestinal complaints and had a longer delay in the diagnosis of CeD. CONCLUSIONS: There is a significant delay in the diagnosis of CeD since the onset of its symptoms. The severity of celiac disease increases with increasing delay in its diagnosis. There is a need to keep a low threshold for the diagnosis of CeD in appropriate clinical settings.

BACKGROUND AND AIM: While European Society of Pediatric Gastroenterology Hepatology and Nutrition advocates a no-biopsy pathway for the diagnosis of celiac disease (CeD) in children if IgA anti-tissue transglutaminase antibody (anti-tTG ab) titer is ≥10-fold upper limit of normal (ULN) and have a positive IgA anti-endomysial antibody (EMA); the data for anti-tTG Ab titer-based diagnosis of CeD in adults is still emerging. We planned to validate if IgA anti-tTG Ab titer ≥10-fold predicts villous abnormalities of modified Marsh grade ≥2 in Asian adult patients with CeD. METHODS: We recruited 937 adult patients with positive anti-tTG Ab from two databases, including AIIMS Celiac Clinic and Indian National Biorepository. The diagnosis of definite CeD was made on the basis of a positive anti-tTG Ab and the presence of villous abnormalities of modified Marsh grade ≥2. RESULTS: Of 937 adult patients with positive anti-tTG Ab, 889 (91.2%) showed villous abnormalities of modified Marsh grade ≥2. Only 47.6% of 889 adults with CeD had anti- tTG Ab titers of ≥10-fold. The positive predictive value (PPV) and specificity of anti tTG Ab titer ≥10-fold for predicting modified Marsh grade ≥2 were 99.8% and 98%, respectively. At anti-tTG Ab titer ≥11-fold, specificity and PPV were 100% for predicting villous abnormalities of modified Marsh grade ≥2. CONCLUSIONS: Approximately 50% of adults with CeD may benefit from the no biopsy pathway, reducing the health burden and risks of gastroscopy/anesthesia.

The objective of the study was to estimate genetic parameters of the growth traits under Bayesian inference in Harnali sheep. The information of pedigree and targeted traits of 2404 Harnali animals born to 159 sires and 695 dams was collected for the period from 1998 to 2021. The growth traits included weight at birth (BWT), 3 (WWT), 6 (6WT) and 12 (YWT) months of age. The genetic evaluation was carried out using six univariate animal models comprising direct and maternal effects using THRGIBBS1F90 and POSTGIBBSF90 programs. The fixed factors adjusted in the analysis were period of birth, sex of lamb and dam's weight at lambing. Bayesian estimates of direct heritability under best model for BWT, WWT, 6WT and YWT traits were 0.16 ± 0.04, 0.10 ± 0.04, 0.18 ± 0.04, and 0.05 ± 0.03, respectively. The significant maternal influences observed for BWT and WWT traits with 9% and 8% contribution to total phenotypic variances, respectively. Additionally, maternal permanent environmental influences were observed to BWT (4%) and YWT trait (3%). The genetic and phenotypic correlations among studied traits were high and positive. The genetic changes were positive and significant for WWT only. It was concluded that the weight at 6 months of age can be continued as selection criterion for further genetic improvement through selection. Also, maternal effects should be considered in breeding programme for enhancing early growth performance in Harnali sheep.
RESUMO
OBJECTIVES: Chemical peels are used to treat photoageing, pigmentation, improve complexion and dull skin, fine lines and scars. The objective of this study is to do comparative analysis of Lactic Acid 30% with Ferulic peel 12% (combination peel) versus TCA 10% with Ferulic peel 12% (combination peel) for Photoageing Skin. MATERIALS AND METHODS: This is a retrospective study from September 2021 to 2022 with total 50 female patients aged between 25 and 40 years were treated. Randomisation of patients was done (simple randomisation using lottery method) for both groups with 25 patients enrolled in each group. The first group (Group A-25 patients) were treated with lactic acid 30% with Ferulic peel 12% (combination peel). The second group (Group B-25 patients) were treated with TCA 10% with Ferulic peel 12% (combination peel). Inclusion and exclusion criteria have been defined for the study. Two scales have been used for assessing the results: Allergan Skin Roughness Scale (ASRS) and Allergan Fine Line Scale (AFLS). ASRS and AFLS scores were assessed at pre-treatment (pre) and post treatment (post-1 month after last peel session). Data were summarised in Mean ± SD (standard deviation). Pre and post groups were compared by paired t test. The pre to post change in outcome measures between two independent groups were compared by independent Student's t test. Discrete (categorical) groups were compared by Chi-square (χ2) test. A two-tailed (α=2) P < 0.05 was considered statistically significant. Analyses were performed on SPSS software (Windows version 22.0). Patients were followed up for 6 months post treatment. RESULTS: In Group A, comparing the pre and post ASRS score, paired t test showed significant (P < 0.001) decrease or improvement of 56.1%. In Group B, comparing the pre and post ASRS score, paired t test showed significant (P < 0.001) decrease or improvement of 52.8%. Comparing the pre to post mean decrease or improvement in ASRS score of two groups, Student's t test showed similar (P > 0.05) improvement between the two groups though it was 2.5% higher in Group B as compared to Group A. In Group A, comparing the pre and post AFLS score, paired t test showed significant (P < 0.001) decrease or improvement of 63.2% at post as compared to pre. In Group B, comparing the pre and post AFLS score, paired t test showed significant (P < 0.001) decrease or improvement of 58.8% at post as compared to pre. Further, comparing the pre to post mean decrease or improvement in AFLS score of two groups, Student's t test showed similar (P > 0.05) improvement between the two groups though it was 16.7% higher in Group A as compared to Group B. CONCLUSION: Study found both the treatments equally effective in the management of ageing skin after 6 months of treatment. However, study needs further validation on larger sample size, varied age groups and male gender. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

RESUMO
Cellular and genetic understanding of the rice leaf size regulation is limited, despite rice being the staple food of more than half of the global population. We investigated the mechanism controlling the rice leaf length using cultivated and wild rice accessions that remarkably differed for leaf size. Comparative transcriptomics, gibberellic acid (GA) quantification and leaf kinematics of the contrasting accessions suggested the involvement of GA, cell cycle and growth-regulating factors (GRFs) in the rice leaf size regulation. Zone-specific expression analysis and VIGS established the functions of specific GRFs in the process. The leaf length of the selected accessions was strongly correlated with GA levels. Higher GA content in wild rice accessions with longer leaves and GA-induced increase in the leaf length via an increase in cell division confirmed a GA-mediated regulation of division zone in rice. Downstream to GA, OsGRF7 and OsGRF8 function for controlling cell division to determine the rice leaf length. Spatial control of cell division to determine the division zone size mediated by GA and downstream OsGRF7 and OsGRF8 explains the leaf length differences between the cultivated and wild rice. This mechanism to control the rice leaf length might have contributed to optimizing leaf size during domestication.

BACKGROUND: While celiac disease (CeD) is considered to affect primarily the small intestine, pathological changes in other parts of the gastrointestinal tract (GIT) are also known to occur. IgA anti-tissue transglutaminase-2 antibody (anti-TG2 Ab) deposits at the site of involvement is one of the methods to establish CeD-related tissue pathology. AIMS: To explore the utility of IgA anti-TG2 Ab deposits in pan-gastrointestinal mucosal biopsies as evidence of CeD-related pathologies. METHODS: Forty-two treatment-naive patients with CeD and 45 patients with irritable bowel syndrome were included as cases and controls, respectively. Mucosal biopsies were collected from the esophagus, stomach, duodenum, and rectosigmoid regions at baseline from cases and controls, and additionally after 6-months of gluten-free diet in cases. All biopsies were evaluated for histological changes and subjected to dual-color immunohistochemical staining for identifying IgA anti-TG2 Ab deposits. RESULTS: Significantly higher number of patients with CeD had lymphocytic esophagitis (9.7% vs. 0%, P = 0.05), lymphocytic gastritis (35% vs. 8.8%, P < 0.01) and lymphocytic colitis (17.4% vs. 0%, P < 0.05) than that in controls. IgA anti-TG2 Ab deposits were observed in significantly more numbers in esophagus (30.9% vs. 6%, P < 0.001), stomach (62.2% vs. 9.3%, P < 0.01), duodenum (88.5% vs. 0%, P < 0.001) and rectum (17.4% vs. 0%, P < 0.05) than that in controls. There was a decline, but not statistically significant, in severity of lymphocytosis and intensity of IgA anti-TG2 Ab deposits in follow-up biopsies. CONCLUSION: Significantly higher number of patients with CeD had evidence of lymphocytic infiltration and IgA anti-TG2 deposits along GIT suggesting that CeD affects other parts of GIT.

BACKGROUND: Medical equipment plays a crucial role in the provision of quality healthcare services, despite this more than 50% of equipment in developing countries are non-functioning due to a lack of appropriate human resources to maintain. To address this problem some government hospitals of Nepal have deployed a mid-level technical cadre called 'Biomedical Equipment Technician' (BMET). This study aims to evaluate the effectiveness of deploying a BMET on the functionality of medical equipment in government hospitals of rural Nepal. METHODS: We used a mixed-methods approach with a comparative research design. A comprehensive range of 2189 pieces of medical equipment at 22 hospitals with and without BMET were observed to assess their functional status. Medical equipment were stratified into 6 categories based on department and T tests were conducted. We collected qualitative data from 9 BMETs, 22 medical superintendents, and 22 health staff using semi-structured interviews and focus-group discussions. Thematic content analysis was conducted to explore how the BMET's work was perceived. FINDINGS: The quantity of non-functional devices in hospitals without BMETs was double that of hospitals with BMETs (14% and 7% respectively, p < 0.005). Results were similar across all departments including General (16% versus 3%, p = 0.056), Lab (15% versus 7%, p < 0.005) and Operation Theater (14% versus 5%, p < 0.005). Hospitals with BMETs had fewer overall non-functional devices requiring simple or advanced repair compared to hospitals without BMETs [3% versus 7% (p < 0.005) simple; 4% versus 6% (p < 0.005) advanced]. In our qualitative analysis, we found that BMETs were highly appreciated by hospital staff. Hospital workers perceived that having a BMET on staff, rather than twice-yearly visits from central-level maintenance technicians, is an effective way to keep medical equipment functional. However, without a favorable working environment, the BMET alone cannot perform optimally. CONCLUSIONS: Having a BMET at a rural government hospital has a substantial positive effect on the functional status of medical devices at the hospital. BMETs should be deployed at all rural hospitals to increase the functionality of medical devices, thereby improving the working environment and quality of health services provided.

The present study evaluated maternal and additive influences that contribute to phenotypic variation in various growth traits in Munjal sheep. The targeted traits that pertained to 2278 records of 706 lambs were birth weight (BWT), weaning weight (WT3), 6-month body weight (WT6), 12-month body weight (WT12), average daily gain (ADG1: 0-3 months; ADG2: 3-6 months, ADG3: 6-12 months of age) and their corresponding Kleiber ratios designated as KR1, KR2 and KR3. The direct heritability estimates for BWT, WT3, WT6, WT12, ADG1, ADG2, ADG3, KR1, KR2 and KR3 under animal models were 0.20 ± 0.08, 0.28 ± 0.08, 0.17 ± 0.07, 0.47 ± 0.09, 0.33 ± 0.08, 0.09 ± 0.06, 0.36 ± 0.10, 0.33 ± 0.08, 0.09 ± 0.06 and 0.32 ± 0.10, respectively. The estimates of maternal genetic effects contributed significantly and were 8% and 7% for BWT and WT3 traits, respectively, which highlighted the considerable role of maternal effects on early growth traits. Genetic and phenotypic correlations ranged from moderate to high between weaning and post-weaning traits. It was concluded that early selection that considered additive as well as maternal effects at weaning age may be delivered to the desired genetic progress in Munjal sheep.

The present study was carried out to estimate lamb survival (in days) from birth to weaning under survival analysis using data records from 2057 Harnali lambs born to 134 sires and 623 dams between the period from 2001 to 2020. The weaning age in resourced population was 90 days from birth. The hazard ratio in terms of risk of death up to weaning was determined using Cox proportional hazards model by subjecting some fixed factors such as year of birth, sex of lamb, birth weight (kg), dam's weight at lambing (kg) and dam's age at lambing (years). The overall survivability up to weaning among lambs was 91.59% and Kaplan-Meier estimates of mean survival time up to weaning was 85.77 days. Cox proportional hazard modelling revealed that the hazards of death up to weaning was higher in male lambs [1.66, 95% confidence interval (CI): 1.22-2.26] compared with female lambs [hazard ratio (HR) = 1.00]. It was also observed that the hazards of death (HR = 0.91, 95% CI: 0.88-0.94) had decreasing trends over years. For birth weight (kg), hazard rate was 0.34 (95% CI: 0.25-0.46), which indicated that the risk of pre-weaning mortality was lower as birth weight increases. The weight and age of dams at lambing did not influence the survival time of studied population. The present findings indicated that survival time increased in studied lambs over the years and it could be increased more by giving more emphasis on better litter weight and general health aspects at farm level.

The present work evaluated animal models comprising direct and maternal effects to estimate (co)variance components and genetic parameters of growth rates and Kleiber ratio in Harnali sheep. The information on pedigree and targeted traits of 1862 lambs born to 144 sires and 591 dams was collected for the period from 1998 to 2018. The traits studied were average daily gain from birth to 3 months of age (ADG1), 3 months to 6 months of age (ADG2), and 6 months to 12 months of age (ADG3) and their corresponding Kleiber ratios as KR1, KR2 and KR3, respectively. The statistical methods included the general linear model for analyzing the effects of fixed factors and animal models for deriving variance components for targeted traits. According to best model evaluated on the basis of likelihood ratio test, the estimated direct heritability was low in magnitude and ranged from 0.04 to 0.14. Direct heritability estimates for ADG1, ADG2, ADG3, KR1, KR2 and KR3 were 0.06, 0.14, 0.05, 0.04, 0.11 and 0.05, respectively. The maternal genetic effects contributed (4-7%) significantly for ADG1, KR1 and KR2 traits. The genetic correlations ranged from -0.35 ± 0.11 (ADG1-KR2) to 0.98 ± 0.01 (ADG2-KR2 and ADG3-KR3) and phenotypic correlations ranged from -0.36 ± 0.02 to 0.98 ± 0.01 for ADG1-KR2 and ADG2-KR2, respectively. The significant maternal effects along with low levels of direct effects for average daily gain and Kleiber ratio at different age group should be considered while setting selection and managerial strategies to achieve anticipated growth rates in Harnali sheep.

The evaluation of early reproduction traits in Beetal goat was performed for possible effects of genetic and non-genetic factors on litter size at birth (LSB), litter size at weaning (LSW), litter weight at birth (LWB), litter weight at weaning (LWW) and age at first kidding (AFK). The data records consisted of information of pedigree and targeted traits pertained to 223 does born to 25 sires and 122 dams between the years 2004 to 2019. A general linear model was used for assessment of non-genetic factors such as period of birth, type of birth and dam's weight at kidding on studied traits. Genetic evaluation of targeted traits was done to estimate variance components and genetic parameters under dyadic mixed modelling. The estimates of least-square means for LSB, LSW, LWB, LWW and AFK were observed as 1.27 ± 0.03, 1.25 ± 0.03, 3.24 ± 0.07 kg, 13.08 ± 0.30 kg and 27.56 ± 0.58 months, respectively. Only the period of birth showed significant (P < 0.05) effects for targeted traits in this study. The estimates of direct heritability for LSB, LSW, LWB, LWW and AFK were low in magnitude as 0.08, 0.03, 0.10, 0.03 and 0.06, respectively. The moderate to high genetic and phenotypic correlations among litter traits indicate simultaneous improvement for these traits. It was concluded that low ranged direct heritability estimates for targeted traits indicated modest scope for genetic improvement of reproductive efficiency in Beetal goat through selection and, therefore, adoption of improved managerial practices is necessary to improve reproductive efficiency of Beetal goat.

Lamb survival is a critical aspect in the sheep industry as it increases the chances of economic gain in the flock. The objective of the current study was to assess the incidence of lamb mortality in Harnali sheep and to estimate maternal and additive genetic effects of lamb survival using the data of 2057 lambs born to 134 sires and 623 dams for the period of 20 years (2001-2020). The genetic evaluation was carried out using threshold animal models comprising direct and maternal effects using THRGIBBS1F90 and POSTGIBBSF90 programs. Cumulative mortality (95% CI (confidence interval)) for the S1 (lambs which died up to weaning age), S2 (lambs which died from birth to 6 months of age) and S3 (lambs which died from birth to 12 months of birth) groups was 8.41 (7.21-9.61), 14.10 (12.59-15.60) and 17.70 (16.05-19.34) %, respectively. The logistic regression analysis revealed significant (p < 0.05) influences of non-genetic factors and indicated that the female lambs, heavier dam and higher birth weight of lamb were associated with better survival as compared to their counterparts. The estimates of direct additive heritability for S1, S2 and S3 were 0.04 ± 0.01, 0.07 ± 0.03 and 0.11 ± 0.04, respectively. In addition to this, significant influences of the maternal permanent environmental effects were observed for lamb survival up to weaning as well as six months of age. Thus, the present findings suggest that lamb survival could be improved through better management practices but consideration of maternal permanent environmental effects is important for initial survival of the lamb.

BACKGROUND: Intestinal flora plays a critical role in immunity against hepatitis B virus (HBV). Fecal Microbiota Transplantation (FMT) may be a potential immunomodulatory therapy in patients with chronic hepatitis B (CHB). AIM: We aimed to study role of FMT in hepatitis B e antigen (HBeAg)-positive CHB patients in terms of its effect on HBeAg, HBsAg, and HBV DNA. METHODS: HBeAg-positive patients despite being on antiviral treatment for > 1 year were given six cycles of FMT via gastroscope (nasoduodenal route) at 4 weekly intervals along with antiviral therapy. Twelve out of 14 included patients in FMT arm completed six cycles. Another 15 HBeAg-positive patients who were on oral antivirals for > 1 year were taken as control-antiviral therapy (AVT) arm. Per-protocol analysis was done. RESULTS: The median (interquartile range) age in the FMT and AVT arm were 29 (25-35) and 29(24-38), respectively (P = 0.794). The median (interquartile range) duration of AVT prior to inclusion in the study was 80 (52-104) and 76 (52-114) months in FMT and AVT arm, respectively (P = 0.884). In the FMT arm, 16.7% (2/12) patients had HBeAg clearance in comparison to none in the AVT arm (P = 0.188). None of the patients in either arm had HBsAg loss. The FMT was tolerated well, 42.8% (6/14) patients reported one or more minor adverse events. CONCLUSIONS: In this non-randomized pilot study, FMT appears to be safe and potentially effective in terms of viral suppression and HBeAg clearance in patients with HBeAg-positive CHB. Further randomized controlled trials are needed in order to obtain robust conclusions.

The purpose of the present study was to obtain estimates of variance components and genetic parameters for direct and maternal effects on various growth traits in Beetal goat by fitting four animal models, attempting to separate direct genetic, maternal genetic and maternal permanent environmental effects under restricted maximum likelihood procedure. The data of 3,308 growth trait records of Beetal kids born during the period from 2004 to 2019 were used in the present study. Based on best fitted models, the direct additive h2 estimates were 0.06, 0.27, 0.37, 0.17 and 0.10 for birth weight (BWT), weight at 3 (WT3), 6 (WT6), 9 (WT9) and 12 (WT12) months of age, respectively. Maternal permanent environmental effects significantly contributed for 10% and 7% of total variance for BWT and WWT, respectively, which reduced direct heritability by 40 and 10% for respective traits from the models without these effects. For average daily gain (ADG1) and Kleiber ratios (KR1) up to weaning period (3 months) traits, maternal permanent environmental effects accounted for 7% and 8% of phenotypic variance, respectively, and resulted in a reduction of 6.6% and 5.4% in direct h2 of respective traits. For post-weaning traits, the maternal effects were non-significant (p > .05) which indicates diminishing influence of mothering ability for these traits. High and positive genetic correlations were obtained among WT3-WT6, WT6-WT9 and WT9-WT12 with correlations of 0.96 ± 0.25, 0.84 ± 0.23 and 0.90 ± 0.13, respectively. Thus, early selection at weaning age can be practised taking into consideration maternal variation for effective response to selection in Beetal goat.

OBJECTIVES: Chemical peels are used to treat fine lines, photoaging, skin discoloration and scars. The objective of this study is to do a comparative analysis of lactic acid 30 % with ferulic peel 12 % (combination peel) versus ferulic peel 12% alone as a monotherapy for photoaging. MATERIALS AND METHODS: This is a prospective study from Feb 2016 to 2020 in which a total of 60 female patients with ages between 25 and 36 years were treated. Randomization of patients was done for both groups with 30 patients enrolled in each group. The first group of 30 patients was treated with ferulic peel 12 % (hydroalcohol base) with L-ascorbic acid 15% as a sealer alone (i.e., Group A). In the second group, 30 patients were treated with lactic acid 30 % with ferulic peel 12% (hydroalcohol base) with L-ascorbic acid 15% as a sealer (combination peel) (i.e., Group B). Inclusion and exclusion criteria have been defined for the study. Two scales have been used for assessing the results, Allergan Skin Roughness Scale (ASRS) and Allergan Fine Line Scale (AFLS). ASRS and AFLS scores were assessed at pre-treatment (pre) and post-treatment (post 1 month after last peel session) and compared using Student's paired t test and independent t test. RESULTS: The results showed significant and higher improvement of 27% and 42%, respectively, in ASRS (1.37 ± 0.49 vs. 1.87 ± 0.51, diff = 0.50, 95% CI = 0.24 to 0.76, p < 0.001) and AFLS (1.20 ± 0.41 vs. 2.07 ± 0.58, diff = 0.87, 95% CI = 0.61-1.13, p < 0.001) scores in patients treated with lactic acid and ferulic peel as compared to patients treated with ferulic peel alone. No complications were observed in our study. CONCLUSION: The study found the combination of lactic acid and ferulic peel significantly more effective than ferulic peel alone in the management of fine lines, photoaging and skin discoloration. The findings of this study may need to be further validated on a larger sample size and multicentric analysis. Initial results of our 4-year study have yielded promising results.

Recombinant protein production (RPP) in Escherichia coli (E. coli) often induces metabolic burden to the cells that compromise their overall growth and productivity. Amino acid starvation due to RPP is a major contributor of the metabolic burden on the cells and induces global stress response known as a stringent-like response. In this study, the effect of amino acid supplementation in a chemically defined medium on cellular growth and recombinant pramlintide production was investigated. Based on the consumption profile, few amino acids were categorized as growth-promoting (GP1) and protein production promoting (GP2). Feeding strategies of GP1 and GP2 were tested in shake flasks followed by scale up into the bioreactor. A 40% increase in the recombinant pramlintide (rPramlintide) production (protein concentration of 3.09 ± 0.12 g/L and yield of 227.69 ± 19.72 mg pramlintide per gram dry cell weight) was realized. Furthermore, transcriptomics data indicated the downregulation of several genes associated with global stress response and genes involved in amino acid biosynthesis in test culture, supported by proteomics analysis. These results signify that the external supply of critical amino acids decreases cellular stress during RPP and improves process productivity.

BACKGROUND AND AIM: There is a paucity of data on the clinical presentations and outcome of Budd-Chiari syndrome (BCS) patients presenting as acute-on-chronic liver failure (BCS-ACLF). We aimed to describe the profile and outcomes of endovascular interventions in patients with BCS-ACLF. METHODS: All BCS-ACLF patients presenting between October 2007 and April 2019 satisfying the Asian Pacific Association for the Study of the Liver (APASL) definition were studied. We compared 30- , 90- and, 180-day survival among BCS-ACLF patients who underwent endovascular intervention with those who did not, and with a historical cohort of Child-C BCS patients without ACLF who underwent endovascular intervention. RESULTS: Twenty-eight (5%) of 553 BCS patients presented as ACLF as per APASL definition. The majority (60.7%) were males, and mean age was 29.6 ± 11.2 years. The most common site of the block was isolated involvement of hepatic veins-HV (68%), followed by combined inferior vena cava (IVC) and HV block (25%) and isolated IVC block (7%). The acute precipitants were stent thrombosis (17.9%), acute HV thrombosis (10.7%), acute viral hepatitis (7.1%), and antituberculosis drug with hepatitis B virus reactivation (3.6%). In 60.7% patients, no acute precipitant could be identified. The 30- , 90- , and 180-day survival in BCS-ACLF post-endovascular intervention (n = 15), BCS-ACLF without endovascular intervention (n = 13), and Child-C BCS without ACLF who underwent endovascular intervention (n = 25) were (93%, 87%, and 87%), (46%, 28%, and 0%) and (96%, 92%, and 88%), respectively (log-rank test, p value < 0.001). On multivariate Cox proportional analysis, endovascular intervention and the presence of hepatic encephalopathy were independent predictors of mortality. CONCLUSION: Budd-Chiari syndrome can present as acute-on-chronic liver failure. Endovascular intervention is associated with an improved outcome.
