Selenium Alleviates the Adverse Effect of Drought in Oilseed Crops Camelina (Camelina sativa L.) and Canola (Brassica napus L.).

Drought poses a serious threat to oilseed crops by lowering yield and crop failures under prolonged spells. A multi-year field investigation was conducted to enhance the drought tolerance in four genotypes of Camelina and canola by selenium (Se) application. The principal aim of the research was to optimize the crop yield by eliciting the physio-biochemical attributes by alleviating the adverse effects of drought stress. Both crops were cultivated under control (normal irrigation) and drought stress (skipping irrigation at stages i.e., vegetative and reproductive) conditions. Four different treatments of Se viz., seed priming with Se (75 µM), foliar application of Se (7.06 µM), foliar application of Se + Seed priming with Se (7.06 µM and 75 µM, respectively) and control (without Se), were implemented at the vegetative and reproductive stages of both crops. Sodium selenite (Na2SeO3), an inorganic compound was used as Se sources for both seed priming and foliar application. Data regarding physiochemical, antioxidants, and yield components were recorded as response variables at crop maturity. Results indicated that WP, OP, TP, proline, TSS, TFAA, TPr, TS, total chlorophyll contents, osmoprotectant (GB, anthocyanin, TPC, and flavonoids), antioxidants (APX, SOD, POD, and CAT), and yield components (number of branches per plant, thousand seed weight, seed, and biological yields were significantly improved by foliar Se + priming Se in both crops under drought stress. Moreover, this treatment was also helpful in boosting yield attributes under irrigated (non-stress) conditions. Camelina genotypes responded better to Se application as seed priming and foliar spray than canola for both years. It has concluded that Se application (either foliar or priming) can potentially alleviate adverse effects of drought stress in camelina and canola by eliciting various physio-biochemicals attributes under drought stress. Furthermore, Se application was also helpful for crop health under irrigated condition.

Evaluation of antipyretic activity of some medicinal plants from Cholistan desert Pakistan.

Traditional herbal healers "Hakims" use various plants of the Cholistan desert, Pakistan for treating a number of infectious and non-infectious diseases. However, there has never been a scientific validation of these plant-based therapeutics. We compared the antipyretic effect of Echinops echinatus, Alhagi maurorum, Fagonia cretica, Cymbopogon jwarancusa and Panicum turgidum in animal model. These plants were used to reduce E.coli lysate induced pyrexia in rabbits. There were five groups of rabbits having five rabbits in each group. Among these five groups, three received various doses of experimental treatment, paracetamol was given to fourth group known as positive control. The fifth group of animals served as negative control and received no treatment. Ethanol extracts of Fagonia cretica (500 mg/kg), Panicum turgidum (500 mg/kg and 750 mg/kg), Alhagi maurorum (500 and 750 mg/kg), Cymbopogon jwarancusa (250 mg/kg) and Echinops echinatus (750 mg/kg) showed significant antipyretic effects when compared with controls and experimental counterparts. These results revealed that ethanol extracts of the plants evaluated in this study have dose dependent antipyretic activity. Further detailed screening of these plant species is recommended.

The structure of NtdA, a sugar aminotransferase involved in the kanosamine biosynthetic pathway in Bacillus subtilis, reveals a new subclass of aminotransferases.

NtdA from Bacillus subtilis is a sugar aminotransferase that catalyzes the pyridoxal phosphate-dependent equatorial transamination of 3-oxo-α-D-glucose 6-phosphate to form α-D-kanosamine 6-phosphate. The crystal structure of NtdA shows that NtdA shares the common aspartate aminotransferase fold (Type 1) with residues from both monomers forming the active site. The crystal structures of NtdA alone, co-crystallized with the product α-D-kanosamine 6-phosphate, and incubated with the amine donor glutamate reveal three key structures in the mechanistic pathway of NtdA. The structure of NtdA alone reveals the internal aldimine form of NtdA with the cofactor pyridoxal phosphate covalently attached to Lys-247. The addition of glutamate results in formation of pyridoxamine phosphate. Co-crystallization with kanosamine 6-phosphate results in the formation of the external aldimine. Only α-D-kanosamine 6-phosphate is observed in the active site of NtdA, not the ß-anomer. A comparison of the structure and sequence of NtdA with other sugar aminotransferases enables us to propose that the VIß family of aminotransferases should be divided into subfamilies based on the catalytic lysine motif.

A previously unrecognized kanosamine biosynthesis pathway in Bacillus subtilis.

The ntd operon in Bacillus subtilis is essential for biosynthesis of 3,3'-neotrehalosadiamine (NTD), an unusual nonreducing disaccharide reported to have antibiotic properties. It has been proposed that the three enzymes encoded within this operon, NtdA, NtdB, and NtdC, constitute a complete set of enzymes required for NTD synthesis, although their functions have never been demonstrated in vitro. We now report that these enzymes catalyze the biosynthesis of kanosamine from glucose-6-phosphate: NtdC is a glucose-6-phosphate 3-dehydrogenase, NtdA is a pyridoxal phosphate-dependent 3-oxo-glucose-6-phosphate:glutamate aminotransferase, and NtdB is a kanosamine-6-phosphate phosphatase. None of these enzymatic reactions have been reported before. This pathway represents an alternate route to the previously reported pathway from Amycolatopsis mediterranei which derives kanosamine from UDP-glucose.

Screening of hepatitis B and C viral infection, recognition of risk factors, and immunization of patients against hepatitis B virus: a module developed for effective hepatitis control.

Introduction: The continually increasing incidence of hepatitis, a worldwide health issue, in Pakistan, has highlighted the need to investigate the epidemiology factors and implement preventive measures accordingly. The purpose of this study was to scrutinize the prevalent and significantly associated risk factors of hepatitis in students and employees, screening them for hepatitis B and C virus and vaccinating them against HBV to make IUB hepatitis free. Methodology: A total of 12,912 participants including students (n = 10,948) and employees (n = 1964) were screened for HBV and HCV via immunochromatographic test. Hepatitis- positive participants' blood samples were further tested and viral load was estimated by quantitative PCR. All the hepatitis-negative participants were vaccinated against HBV. The demographic and risk factors-related data were collected using the questionnaire. Statistical analysis (Chi-square test and bivariate regression analysis) was performed using SPSS software to explore any association between risk factors and hepatitis. Results: Results indicated that 662/12912 participants (students = 478/10,948, employees = 184/1,964) tested positive for hepatitis. Among them, HCV was observed to be more prevalent than HBV among the study participants, employees, and students, and viral count was low in both HBV and HCV-infected participants. However, men were more affected than women. The studied risk factors represented higher frequency among hepatitis-positive participants relative to the hepatitis-negative participants. The Chi-square test revealed that students' gender, history of hepatitis in the family and relatives, dental treatment, sharing cosmetics and shaving blades were significant (p > 0.005) risk factors of hepatitis while in the employees group surgery and age were significant. Moreover, the reused of syringes was found to be associated with hepatitis in both groups. The bivariate analysis helped to identify various new risk factors which were independently, either positively or negatively, associated with hepatitis. Discussion: Our study enabled us to recognize different risk factors of hepatitis among the target population. The information thus generated can be usefully applied in planning hepatitis awareness, targeted screening, and effective control programs for other target populations. In general, this module can be further utilized for any other disease.

LC-ESI-MS analysis, antioxidant, anti-diabetic and molecular docking studies on Corchorus depressus (L.) C.Chr.

The present study encompasses the ethnomedicinal consumption of Corchorus depressus (L.) C.Chr. (C. depressus) for diabetes. Samples were subjected to LC-ESI-MS analyses. The n-hexane, methanolic and water extracts were screened for α-glucosidase inhibition and in vivo anti-diabetic studies. Further, antioxidant (DPPH) and anti-inflammatory study was performed via luminol-enhanced chemi-luminescence assay. The identified compounds were docked against the target enzymes of diabetes. The n-hexane fraction (CD-J1) showed IC50 of 8.4 ± 0.1 µg/mL against α-glucosidase enzyme. The sub fractions CD-12 and CD-13 of CD-J1 obtained after flash column chromatography displayed further reduced IC50 values of 4.3 ± 0.1 and 6.3 ± 0.1, respectively, as compared with standard drug acarbose (IC50 values of 37.5 ± 0.2 µg/mL). Simultaneously, dereplication of most active sub-fraction CD-12 by LC-ESI-MS led to the identification of strophanthidin and some other active metabolites responsible for anti-diabetic activity. Molecular docking of strophanthidin with α-glucosidase and α-amylase revealed high affinity for these target enzymes.

Ameliorating effect of fish oil on acrylamide induced oxidative stress and neuronal apoptosis in cerebral cortex.

Acrylamide (ACR) is a known industrial toxic chemical that produce neurotoxicity characterized by progressive neuronal degeneration. This study was designed to investigate the protective effect of fish oil on ACR-induced neuronal damage in Wistar rats. ACR enhances the production of reactive oxygen species and potentially affects brain. ACR administered rats showed increased levels of lipid peroxidative product, protein carbonyl content, hydroxyl radical and hydroperoxide which were significantly modulated by the supplementation of fish oil. The activities of enzymic antioxidants and levels of reduced glutathione were markedly lowered in ACR-induced rats; fish oil treatment augmented these antioxidant levels in cortex. Free radicals generated during ACR administration reduced the activities of membrane adenosine triphosphatases and acetylcholine esterase. Fish oil enhanced the activities of these enzymes near normal level. Histological observation represented the protective role of fish oil in ACR-induced neuronal damage. Fish oil reduced the ACR-induced apoptosis through the modulation in expressions of B-cell lymphoma 2 (Bcl2)-associated X protein and Bcl2-associated death promoter. Further, fish oil increases the expression of heat shock protein 27 (Hsp27) in ACR-induced rats. This study provides evidence for the neuroprotective effect of fish oil on ACR-induced neurotoxicity by reducing oxidative stress and apoptosis with modulation in the expression of Hsp27.

Betamethasone Dipropionate Derivatization, Biotransformation, Molecular Docking, and ADME Analysis as Glucocorticoid Receptor.

Betamethasone is an important glucocorticoids (GCs), frequently used to cure allergies (such as asthma and angioedema), Crohn's disease, skin diseases (such as dermatitis and psoriasis), systemic lupus erythematosus, rheumatic disorders, and leukemia. Present investigation deals to find potential agonist of glucocorticoid receptors after biotransformation of betamethasone dipropionate (1) and to carry out the molecular docking and ADME analyses. Biotransformation of 1 was carried out with Launaea capitata (dandy) roots and Musa acuminate (banana) leaves. M. acuminate furnished low-cost value-added products such as Sananone dipropionate (2) in 5% yields. Further, biocatalysis of Sananone dipropionate (2) with M. acuminate gave Sananone propionate (3) and Sananone (4) in 12% and 7% yields, respectively. However, Sananone (4) was obtained in 37% yields from Launaea capitata. Compound 5 was obtained in 11% yield after ß-elimination of propionic acid at C-17 during oxidation of compound 1. The structure elucidation of new compounds 2-5 was accomplished through combined use of X-ray diffraction and NMR (1D and 2D) studies. In addition to this, molecular docking and ADME analyses of all transformed products of 1 were also done. Compounds 1-5 showed -12.53 to -10.11 kcal/mol potential binding affinity with glucocorticoid receptor (GR) and good ADME profile. Moreover, all the compounds showed good oral bioavailability with the octanol/water partition coefficient in the range of 2.23 to 3.65, which indicated that compounds 1-5 were in significant agreement with the given criteria to be considered as drug-like.

Anti-arthritic effect of GN1, a novel synthetic analog of glucosamine, in the collagen-induced arthritis model in rats.

OBJECTIVE: Glucosamine is a naturally occurring amino monosaccharide that maintains the elasticity and strength of the cartilage tissues. It has been used to treat osteoarthritis in humans; however, in severe conditions of inflammation and pain, glucosamine alone is not enough, and it is important to improve its biological activity. Our research group has recently taken an interest in the synthetic manipulation of amino sugars to develop some efficient pharmacophores, e.g., ß-D-glucosamine, to combat rheumatoid arthritis, and tested its anti-arthritic effects in the collagen-induced arthritis (CIA) model in rats. METHODS: Arthritis was induced in female Sprague-Dawley rats by multiple intradermal injections of bovine type II collagen and challenged again with the same antigen preparation 7 days later. Arthritis was evaluated by arthritic score, body weight loss, paw volume measurement, and histological changes. RESULTS: The animals in the arthritic control group showed a gradual decrease in their body weight and concurrent increase in the paw volumes compared to the normal control group. In contrast, increased hind paw swelling was significantly suppressed with no further noticeable reduction in body weight in the glucosamine (p < 0.05) and GN1-treated (p < 0.02) arthritic animals. Histopathological evaluation of isolated knee joints by grading system and classification of the stages in arthritic lesion development revealed suppression of the inflammatory changes in the GN1-treated animals. Moreover, both the pro-inflammatory markers C-reactive protein (CRP) and low-density lipoprotein (LDL) levels were found to be significantly decreased in animals treated with GN1 (p < 0.03 for CRP and p < 0.05 for LDL) compared to the arthritic control group. CONCLUSION: These results suggest that GN1 has both anti-arthritic and anti-inflammatory properties. Its effects in the CIA model suggest that it could be useful in the treatment of rheumatoid arthritis.

Kaolin and Jasmonic acid improved cotton productivity under water stress conditions.

Drought is one of the most emerging threat that causes a severe reduction in cotton plant growth and development. Being cotton is a major cash crop has great threat to prevailing drought events in Pakistan. A field experiment was conducted in Kharif season 2018 at Research Area of MNS-University of Agriculture, Multan, Pakistan to assess the role of foliar applied kaolin and jasmonic acid on vegetative growth, gas exchange and reproductive traits of cotton under normal irrigated and artificial water deficit conditions. The experiment was laid -out in a factorial randomized complete block design with split - split plot arrangement. Main plots were allocated for irrigation levels, sub-plots for two -cotton genotypes viz. NIAB - 878 and SLH - 19 while sub - sub plots for treatments of kaolin and Jasmonic acid. Water deficit stress was created by skipping irrigation at flowering for 21 days. Foliar sprays of Kaolin (5%, w/v) and Jasmonic acid (100 µM) were applied alone or in combination at 60 days after planntinon both to normal irrigated and water-stresse skip irrigation while irrigation water alone was sprayed in control plots. Both cotton genotypes responded variably to normal irrigated and skip conditions. Skipping irrigation for up to 21 days at flowering caused a significant decrease in leaf relative water content, SPAD values, net photosynthetic rate and seed cotton yield in both the genotypes. Seed cotton yield showed an overall decline of 24.7% in skip over Normal irrigated crop. The genotype NIAB - 878 produced maximum seed cotton yield of 3.304 Mg ha-1 in normal that dropped to 2.579 Mg ha-1 in skip, thus showing an average decline of 21.9 %. Similarly, SLH - 19 produced 2.537 Mg ha-1 seed cotton under normal that dropped to 1.822 Mg ha-1 in skip, showing an average decline of 28.2%. The Application of Kaolin and JA Jasmonic acid, either applied individually or in combination, improved vegetative and reproductive development of both cotton varieties in normal and skip regimes. However, combined kaolin and Jasmonic Acid application proved to be more beneficial in terms of seed cotton production and other parameters studied.

Synthesis and antileishmanial and antimicrobial activities of some 2,3-disubstituted 3H-quinazolin-4-ones.

A series of 2,3-disubstituted 3H-quinazolin-4-ones was synthesized. Antimicrobial activities of the synthesized compounds were investigated against Gram (+ve) and Gram (-ve) bacteria, including B. subtilis, S. aureus, S. flexneri, P. aeruginosa, and S. typhi, and six fungi, namely Trichophyton longifusus, Candida albicans, Aspergillus flavus, Microsporum canis, Fusarium solani, and Candida glabrata using the broth microdilution method. Compounds 9, 11, and 12 showed significant activities against the selected bacterial cultures, while 7-10, 12, 15, and 16 showed good to moderate antifungal activities. Compound 11 exhibited strongest leishmanicidal activity against Leishmania major (MHOM/PK/88/DESTO) promastigotes, while other compounds showed weak to moderate leishmanicidal activities.

A 12-week prospective randomized controlled comparative trial of vilazodone and sertraline in Indian patients with depression.

BACKGROUND: Depressive disorders are considered to be one of the leading causes of morbidity and mortality accounting for 4.3% of total disability-adjusted life years. Selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors have greater efficacy and lesser side effects; at the same time, these drugs cause sexual dysfunction and weight gain. Vilazodone was supposed to have better efficacy and less sexual dysfunction and weight gain. AIM OF THE STUDY: The aim is to compare efficacy (in terms of Hamilton Depression Rating Scale [HDRS]), sexual dysfunction (in terms of Arizona Sexual Experience Scale [ASEX]), and weight gain caused due to vilazodone and sertraline. MATERIALS AND METHODS: This is a randomized controlled study; 60 patients diagnosed with depressive episode were divided into two groups of 30 each; using block randomization technique, one group was prescribed vilazodone and another sertraline. The groups were compared on the basis of efficacy, weight gain, and sexual dysfunction using HDRS and ASEX at baseline, 4-week, and 12-week intervals. Statistical analysis was done by applying Chi-square test, Fisher's exact test, t-test, and repeated measures ANOVA using Wilks' lambda test. RESULTS: On comparing both vilazodone and sertraline, it was observed that both molecules have equal efficacy in terms of HDRS, but vilazodone does not cause weight gain and sexual dysfunction in terms of ASEX, and these findings are statistically very highly significant. CONCLUSIONS: Our study shows that vilazodone has similar efficacy but can be a better antidepressant due to lesser weight gain and sexual dysfunction compared to sertraline.

A Comparative Study of the Efficacy of Levosulpiride versus Paroxetine in Premature Ejaculation.

BACKGROUND: Premature ejaculation (PME) can be defined as a lack in the normal voluntary control over ejaculation. It is the most common sexual dysfunction encountered by the male populace. In general, these patients presents with distress. Hence, a novel treatment to eliminate their problem is required. Although the role of SSRI has already been established, the high discontinuation rate and other types of sexual dysfunctions associated with SSRIs reduce their efficacy in controlling this menace. Levosulpiride is a new drug indicated in treatment of PE. AIMS AND OBJECTIVES: The objective is to study the efficacy of levosulpiride; paroxetine and their comparison in patients of PE. METHODOLOGY: Index of premature ejaculation (IPE) and intravaginal ejaculation latency time (IELT) were used. A total of 36 patients (18 in each group) were included. The patients were assessed at baseline; at 4 weeks' and at 8 weeks' interval. RESULTS: On comparison the score of IPE in domains of ejaculation control, sexual satisfaction, and the total score of IPE were statistically significant on all the three visits. However, the distress score of IPE and the IELT score were statistically not significant between the two groups. CONCLUSION: No doubt both agents are efficacious in patients of PME but paroxetine is more efficacious than levosulpiride. At the same time, levosulpiride is a lesser studied and used drug hence more research should be done for it.

Assessment of quality of sleep and its association with body mass index among medical consultants working in a medical college in northern India.

BACKGROUND: Medical specialist/consultants are exposed to various factors such as long duty hours, call duties, academics, meetings and regulation of departmental work which has adversely affected their sleep quality. OBJECTIVE: To assess sleep quality and association of body mass index with quality of sleep among medical consultants working in medical college. METHOD AND TOOL: This is a cross-sectional study and was done by convenient sampling technique. Pittsburg Sleep Quality Index (PSQI) was used as the assessment tool which categorizes sleep as good or poor according to the score. Chi-square test was applied to establish an association with the variables. RESULTS: A total of 67 responses were obtained, of which 28 showed good sleep on PSQI. Among consultants having good quality sleep, the majority were females (n=18); aged above 40 years (n=17). No relationship was seen with BMI and chronic disease. Consultants spending more than 85% of the time in bed sleeping (p< 0.006) and those going to bed before 10.30 pm (p<0.026) had good sleep quality. CONCLUSION: Good quality of sleep was observed in females, people above 40 years and those who don't have any chronic disease, though this association of sleep quality with the factors was not significant. Going to bed early (before 10:30 pm) had a positive effect on sleep quality (p<0.026). In general, poor sleep quality was seen among medical consultants.

Biological and phytochemical studies on Capparis decidua (Forssk) Edgew from Cholistan desert.

The present work deals with the biological and phytochemical studies on Capparis decidua (Forssk) Edgew from Cholistan desert of Pakistan. Aerial and floral parts of C. decidua were collected and dried under shade. Powdered materials of each part of C. decidua were extracted with methanol separately, followed by phytochemical studies. Hexane fraction of aerial parts of the C. decidua obtained after solvent-solvent extraction was purified through repeated column chromatography by increasing order of polarity. Four compounds were purified and identified as simiarenol (1), lupeol (2), taraxerol (3) and ß-sitosterol (4). Simiarenol and lupeol were isolated for the first time from genus Capparis. The structures of these compounds were established by comparing the spectroscopic data (1H NMR, 13C NMR, IR, UV & Mass spectrometry) reported in literature. The structure of 1 was further confirmed by XRD analysis. Anti-bacterial activities of crude methanolic extracts were determined against 13 bacterial strains (MIC 250-1000 µg/mL). α-Glucosidase and urease inhibitory activities of pure compounds were also determined. Compounds 1, 2 and 4 showed α-glucosidase inhibition with IC50 at 96.12 ± 0.12, 65.28 ± 0.13 and 128.14 ± 0.17 µM, respectively.

A comparative study of prevalence and predictors of metabolic syndrome in various psychiatric disorders in state of Haryana: More than 30 years Vs. less than 30 years.

BACKGROUND: Exponential growth of metabolic syndrome in psychiatric disorders is becoming alarming situation to handle with. It is associated with reduced life span of 10-30 years in psychiatric patients attributed to metabolic syndrome, thus needs to be screened and addressed in all psychiatric patients. OBJECTIVE: the objective of this study was to know the prevalence and its risk factors in various psychiatric disorder and comparing them in older vs younger patients. METHODOLOGY: A cross sectional indoor based study was conducted after taking ethical committee approval in 140 patients (substance use disorder, schizophrenia, bipolar and depressive disorders). All the metabolic parameters as per International diabetes federation criteria for metabolic syndrome were assessed involving waist circumference, weight, height, Systolic/diastolic blood pressure, fasting blood sugar, high density lipoprotein and triglycerides. STATISTICS: Chi square and t-test were used. RESULTS: It was seen that prevalence of metabolic syndrome (MS); 21.4% in psychiatric illness, up to 40% in major depressive disorders, followed by 33% in substance use disorder and 26.7% in psychotic disorders. Prevalence of MS was higher in older patients >30 years group (26% Vs. 16.4% in <30 years group). It was observed that substance use and depressive disorder and high BP in older male patients are all the significant risk factors for metabolic syndrome. CONCLUSION: More than 1/5th psychiatric patients are affected by metabolic syndrome. Thus, all male psychiatric patients with high BP must be evaluated for metabolic syndrome.

Trends and Patterns of Primary Hepatic Carcinoma in Saudi Arabia.

BACKGROUND: Primary hepatic carcinoma (PHC) is the 4th most common malignancy among males at King Faisal Specialist Hospital and Research center (KFSH & RC) and in Saudi Arabia. There has been a steady increase in the number of PHC cases since 1975 at KFSH & RC and the burden of hepatic carcinomas is growing in Saudi Arabia. The aim of this study is to explore the changing trends and patterns of PHCs at KFSH & RC and conduct a comparative analysis with local, regional and global trends. MATERIALS AND METHODS: Cancer incidence data was obtained from the King Faisal Specialist Hospital and Research Center Tumor Registry program as per the American College of Surgeons standards. Clinico-epidemiological data of 1174 liver cancer patients from KFSH & RC during 2000 to 2014 and Saudi Cancer Registry (SCR) between 2001-2015 with total of 5,796 cases was reviewed. Trends, patterns of occurrence and other prognostic factors of interest were sub-stratified by gender, age, stage, and grade. RESULTS: Temporal trends indicated a rising incidence of PHC from 2001 to 2014 in Saudi Arabia; from 323 cases in 2001 to 376 cases in 2015 as per SCR. A total of 2,779 new cases of PHC were seen at KFSH & RC between 1975 and 2014; the rate of PHC increased from 60 cases in 2004 to 80 cases in 2014. Majority of liver cancers were hepatocellular carcinomas (79.3%) followed by cholangiocarcinoma (11%), and hepatoblastoma (4.7%) with significantly higher incidence among males with a male to female ratio of 2:1 (p <0.01). The highest incidence by age was at 6th and 7th decade of life. Majority of patients were diagnosed in localized stage (44.6%) and had a past medical history (28.2%) of hepatitis (p < 0.001). The most common treatment for liver cancer at KFSH & RC was surgery (26.7%) followed by transplant (9.5%). CONCLUSION: Despite improvement in preventive measures, incidence rates of PHC has increased during the last decade with marked regional variation. Etiology of this escalating trend is multifactorial; predominantly, chronic infection with hepatitis B virus (HBV) and/or hepatitis C virus (HCV), heavy alcohol consumption, obesity, diabetes, and tobacco smoking. This exponential increase may also be due to early detection and diagnosis due to expanding health care delivery in the Kingdom. Further studies are indicated to comprehend the rising trends at the molecular and genetic levels.

Metabolic syndrome in drug naïve schizophrenic patients.

INTRODUCTION: Research in the last decade tried to focus on natural and unnatural causes of death in schizophrenic patients, but recent few years has focussed on emerging cardio-metabolic risk factors, as a cause of mortality in such patients. AIM OF THE STUDY: To assess the determinant of metabolic syndrome in drug naïve schizophrenic patients. METHODOLOGY: It was a cross sectional study; 30 indoor patients with diagnosis of schizophrenia were included. Height, weight, waist circumference and Blood pressure assessment was done by using standard protocol. Fasting Blood Glucose (FBG), Triglyceride (TGs), High Density Lipoprotein (HDL) cholesterol, Low Density Lipoprotein (LDL) total cholesterol were measured. International Diabetes Federation (IDF) criteria was considered for establishing metabolic syndrome. Statistical analysis was done by using chi square and ANOVA. RESULTS: Majority of the patients were females; hailing from rural area; unskilled professional; educated up to below primary level; were single and Hindu by religion. Most common metabolic abnormality was low HDL in 76.6%; High TGs in 26.6%; High SBP ≥130mm Hg in 16.67%; DBP>85mm Hg in 13.33%; High FBS 10% of the patients. In risk assessment strongest risk factors for metabolic syndrome were high waist circumference, FBS and TGs. BMI, total cholesterol, LDL and VLDL were also observed as a risk factors in drug naïve schizophrenic patients. CONCLUSION: HDL, FBS, TGs, waist circumference and BMI are all the strong risk factors for development of metabolic syndrome in drug naïve schizophrenia patients.
