Hystrix brach yura bezoar is calcified undigested material found in the gastrointestinal tract known for various medicinal benefits including as an anticancer agent. However, the H. brachyura population has been declining due to its demand and is under Malaysian law pro tection. Therefore, present study aimed to identify bezoar anticancer active compounds through metabolomics and in - silico approaches. Five replicates of bezoar powder were subjected to extraction using different solvent ratios of methanol - water (100, 75, 5 0, 25, 0% v/v). Cytotoxicity and metabolite profiling using liquid chromatography - mass spectrometry were conducted. Putative compounds identified were subjected to in - silico analysis with targeted anticancer proteins namely, Bcl - 2, Cyclin B/CDK1 complex, V EGF and NM23 - H1. The correlation of LC - MS and cytotoxicity profile pinpointed two compounds, mangiferin and propafenone. In - silico study showed both compounds exerted good binding scores to all proteins with hydrophobic interaction dominating the ligand - pr otein complex binding, suggesting the ligands act as hydrophobes in the interactions.
El bezpar de Hystrix branchyura es material calcificado sin digerir encontr ados en el tracto gastrointestinal, conocido por sus variados beneficios médicos, incluyendo propiedades anticancerosas. De todas formas, la población de H. Branchyura ha ido declinando debido a su demanda y está bajo la protección de la ley de Malasia. Po r esto, este estudio busca identificar los componentes activos anticancerosos del bezoar mediante abordajes metabolómico e in silico. Cinco réplicas de polvo de bezoar fueron sometidos a extracción usando solventes con diferentes proporciones metanol - agua (100, 75, 50, 25, 0% v/v). Se hicieron perfiles de citotoxicidad y de metabolitos usando cromatografía líquida - espectrometría de masa ( LC - MS ). Se identificaron compuestos putativos yse sometieron a a nálisis in silico, buscando las proteínas anticancerosas B cl - 2, complejo Cyclin B/CDK1, VEGF, y NM23 - H1. La correlación LC - MS y el perfil de citotoxicidad identificaron dos compuestos: mangiferina y propafenona. El estudio in silico mostró que ambos compuestos tenían buenos índices de enlace con todas las proteín as con interacción hidrofóbica dominando el enlace complejo proteína - ligando, sugeriendo que los ligandos actúan como hidrófobos en las interacciones

Abstract The red fox (Vulpes vulpes) is a medium-sized carnivore that occurs in different regions of Pakistan, however, still lacks scientific data on its ecology and distribution. The current study investigated the phylogenetic status and diet of the red fox (V.v. griffithii) occurring in Ayubia National Park, Pakistan. Through camera trapping and molecular analysis, we confirmed the occurrence of red fox in the study area. Based on mitochondrial cytochrome B (304 bp) and limited sampling, nearly all red foxes of Ayubia National Park and surrounding Himalayan ranges fall within Holarctic maternal lineage, whereas red foxes found in plains of Pakistan are part of the basal Palearctic maternal lineage. Using 32 scats, we found that red fox diet comprises of 80% animal-based prey species (both wild and domestic) and 19% plant matter. The wild animal prey species included Cape hare (Lepus capensis) and flying squirrel (Pteromyini sp.), which constituted 17% and 15% of diet, respectively. Red foxes infrequently consumed House mouse (Mus musculus), Himalayan Palm civet (Paguma larvata) and sheep (Ovis aries), each comprising around 6% to 9% of red fox diet. The fox species also scavenged on domestic donkey opportunistically. Based on our sampling, our study suggests that the red fox (V.v. griffithii) that occurs in Ayubia National Park and across the lesser Himalayan ranges belongs to Holarctic maternal lineage. The study also highlights consumption of plant seeds by red foxes, indicating it may play an important ecological role in seed dispersal in Ayubia National Park.
Resumo A raposa-vermelha (Vulpes vulpes) é um carnívoro de médio porte que ocorre em diferentes regiões do Paquistão, porém ainda carece de dados científicos sobre sua ecologia e distribuição. O presente estudo investigou o status filogenético e a dieta da raposa-vermelha (V.v. griffithii) que ocorre no Parque Nacional de Ayubia, Paquistão. Por meio de armadilhas fotográficas e análises moleculares, confirmamos a ocorrência de raposa-vermelha na área de estudo. Com base no citocromo B mitocondrial (304 bp) e amostragem limitada, quase todas as raposas-vermelhas do Parque Nacional de Ayubia e áreas circundantes do Himalaia se enquadram na linhagem materna holártica, enquanto as raposas-vermelhas encontradas nas planícies do Paquistão fazem parte da linhagem materna basal paleártica. Usando 32 fezes, descobrimos que a dieta da raposa-vermelha compreende 80% de espécies de presas de origem animal (selvagens e domésticas) e 19% de matéria vegetal. As espécies de presas de animais selvagens incluíram a lebre-do-cabo (Lepus capensis) e o esquilo-voador (Pteromyini sp.), que constituíram 17% e 15% da dieta, respectivamente. As raposas-vermelhas consumiam raramente ratos domésticos (Mus musculus), algas do Himalaia (Paguma larvata) e ovelhas (Ovis aries), cada um compreendendo cerca de 6% a 9% da dieta da raposa-vermelha. A espécie de raposa também se alimentava de burros domésticos de forma oportunista. Com base em nossa amostragem, nosso estudo sugere que a raposa-vermelha (V.v. griffithii) que ocorre no Parque Nacional de Ayubia e nas cordilheiras menores do Himalaia pertence à linhagem materna holártica. O estudo também destaca o consumo de sementes de plantas por raposas-vermelhas, indicando que pode desempenhar um papel ecológico importante na dispersão de sementes no Parque Nacional de Ayubia.
ABSTRACT
@#Introduction: This systematic review aimed to investigate the level of participation, obstacles, and facilitator factors that influence activities of daily living among persons with spinal cord injury (SCI). Methods: A comprehensive search was conducted in four online databases, namely Google Scholar, PubMed, OT Seeker, and Cochrane Library covering the ten-years period from January 2012 to December 2022. Inclusion criteria encompassed original published studies in English focusing on daily activities, work, participation, obstacles, and facilitators in persons with SCI. Non-peer review sources (e.g., abstracts, grey literature, preprints), and studies unrelated to occupational therapy were excluded. The selected studies were assessed for quality using McMaster University Occupational Therapy Evidence-Based Practice critical review form. Results: Out of the 678 articles identified, ten studies were included after the screening, exploring participation in daily living activities, employment, return to work, leisure activities, family tasks, and community mobility among persons with SCI. Obstacles and facilitators influencing participation in activities of daily living were classified using the International Classification of Functioning, Disability, and Health (ICF) framework. This review highlighted that long-term participation is challenging for persons with SCI, affected by obstacles such as body functions, pain, low self-esteem, and environmental and social factors. Conclusion: The findings underscore the importance of adopting a multidisciplinary rehabilitation approach to enhance participation in daily activities for persons with SCI. Occupational therapy plays a significant role in improving participation levels among persons with SCI.

@#Introduction: The use of the lean approach in healthcare has rapidly gained popularity globally, although this approach was more routinely used in the manufacturing sector as opposed to health. Besides, recent studies confirm the suitability of the lean approach applications for improving the quality of medical care. This study aimed to determine the Lean approach’s capacity to improve the waiting time in outpatient clinics in hospitals. Methods: The systematic review approach was employed to help in the research procedures. Search databases used included Ovid, Google scholar, PubMed, MEDLINE, and archive. Besides, search terminologies such as the Lean approach, Hospital-implementation, waiting time, and patient flow were used to help identify sources that best suited the investigation process. Results: The review revealed that the lean approach is suitable for the reduction of waiting times as well as for improving efficiency in the clinic. The outcomes provide a basis for reducing the average waiting time within the hospital. Conclusion: This study recommended that healthcare facilities and departments should take a keen interest in implementing the Lean approaches, as they are crucial for reducing waiting time.
ABSTRACT
@#Introduction: Do Not Resuscitate (DNR) order is a type of Advance Medical Directive (AMD) that documents a patient’s wishes or desire to refrain from Cardiopulmonary Resuscitation (CPR), especially in the terminally ill patient. It is a sensitive issue in patient care and less is known on medical students awareness on the area. Aim: This study assessed the opinion, knowledge, awareness and familiarity toward Do Not Resuscitate (DNR) order among undergraduate medical students from year 1 to 5 in Universiti Sains Malaysia. Methods: A cross-sectional study was conducted with 250 undergraduate medical students using an online questionnaire on awareness towards DNR orders. Descriptive statistics, independent t-test and one-way ANOVA were applied to examine the distribution and association of DNR awareness among medical students with year of study, gender, race and religion. Results: The study indicated that most participants (84.4%) were familiar with DNR orders. There was no significant association between all 4 variables (year of study, gender, race and religion) with level of awareness among undergraduate medical students in HUSM. Conclusion: Undergraduate medical students have a good awareness on DNR orders. Despite having a multiracial and multi religion community, the medical students have similar patterns in their knowledge about DNR.
ABSTRACT
@#Introduction: The consumption of sugar-sweetened beverages (SSBs) among young adults in Malaysia has witnessed a notable increase in recent years, giving rise to concerns regarding the potential adverse health effects, including obesity and diabetes. Despite the urgent need for targeted interventions, there is a dearth of research examining the knowledge, attitudes, and practices (KAP) related to SSBs among Malaysian young adults. To address this research gap, the present study aims to assess the level of KAP concerning SSB intake and its associated factors in this specific population. Methods: A cross-sectional study was conducted involving 408 Malaysian young adults aged between 15 and 29 years. Respondents completed an online questionnaire survey, which encompassed the assessment of socio-demographic characteristics and KAP regarding SSB consumption. The collected data were analyzed using IBM’s Statistical Package for the Social Sciences (SPSS) version 22.0. Spearman correlation tests were performed at a significance level of 0.05. Results: The majority of respondents demonstrated moderate knowledge (60%) and practices (60%), while exhibiting a high positive attitude (100%) towards reducing SSB consumption. Significant correlations were observed between knowledge and attitude (p = 0.003, rs = 0.148) and between knowledge and practice (p = 0.005, rs = 0.138). Moreover, the attitude scores were found to be significantly associated with gender (χ2 (1, N = 408) = 10.421, p = 0.001) and locality (χ2 (1, N = 408) = 4.106, p = 0.043), while the practice scores exhibited a significant association with ethnicity (p = 0.006). Conclusion: This study provides valuable insights into the relationship between KAP related to SSB consumption and socio-demographic factors among Malaysian young adults. The findings underscore the importance of utilizing these insights to develop strategic interventions that aim to curtail SSB consumption and promote a healthy lifestyle, ultimately contributing to the reduction of non-communicable diseases. Health authorities are encouraged to capitalize on these findings to design targeted interventions tailored to the unique needs and circumstances of this population.
ABSTRACT
@#Introduction: This study aims to determine the prognostic factors and survival outcomes of patients that underwent this surgery. Method: A retrospective review of 43 patients who underwent exenteration for periocular malignancies over a 14-year period was carried out. Patient demographics, tumour histology, treatment details, surgical margins’ status and post-operative survival were recorded. The survival outcome examined was the overall survival (OS) rate. Cox regression and Kaplan-Meier analysis were used to evaluate post-exenteration survival. Results: In total, 20 females and 23 males with a median age of 62 ± 17.3 years were identified. The most common indication for exenteration was basal cell carcinoma (20.9%), followed by squamous cell carcinoma (18.6%), adenocystic carcinoma (14%), malignant melanoma (14%) and sebaceous gland carcinoma (11.6%). The independent predictors for worse OS on multivariate analysis were Chinese ethnicity (adjusted hazard ratio [aHR] 4.95, p =0.017), sebaceous gland carcinoma (aHR 57.61 p=0.006), adenocystic carcinoma (aHR 45.87, p=0.008), clear surgical margins (aHR 5.41, p=0.025), receiving only chemotherapy (aHR 169.13, p=0.004), and receiving both adjuvant chemotherapy and radiotherapy (aHR 41.51, p=0.010). Conclusion: We recommend targeted public health initiatives for Chinese patients due to their increased mortality risk from peri-ocular malignancies. In addition, we advise comprehensive adjuvant therapy for all patients regardless of whether a clear surgical margin is achieved. Basal cell carcinoma and adenocystic carcinoma may also benefit from genetic research. We advocate more training for ophthalmologists to identify periocular malignancies earlier for better treatment options and increased chances of survival.
ABSTRACT
@#Introduction: Food security and dietary diversity are critical in ensuring the nutritional and dietary adequacy of mothers. However, since the COVID-19 outbreak, it has become more challenging for mothers to maintain a healthy and varied diet, as more households are reported to be food insecure. Thus, this study aimed to assess food insecurity and its determinants, as well as to determine how it relates to dietary diversity. Methods: A cross-sectional study comprising 200 of B40 mothers with children under the age of two who resided in metropolitan regions of Selangor was conducted. Household Food Insecurity Access Scale (HFIAS) and Minimum Dietary Diversity for Women (MDDW) questionnaires were used to measure food insecurity and dietary diversity, respectively. Results: About 67% of mothers experienced food insecurity and 29.5% experienced dietary monotony. Less than 12 years of education (AOR=4.89, 95% CI=1.87-12.83) and living in a family with six or more people (AOR=3.48, 95% CI=1.20-11.20) were significantly associated with food insecurity. Besides, mothers with a monotonous diet were eight times more likely to be food insecure (AOR=8.03, 95% CI=2.67-24.05). Higher odds of dietary monotony were associated with less than 12 years of education (AOR=2.46, 95% CI=1.13-5.35) and household income contributor of not more than one person (AOR=3.78, 95% CI=1.66-8.60). Conclusion: Food insecurity was associated with an increased chance of dietary monotony among low-socioeconomic women residing in urban community. Therefore, identifying and addressing issues related to poor dietary diversity may allow for preventive and proactive measures to improve their nutritional status and well-being.
ABSTRACT
Background@#In Fiji, 1 in every 3 Fijian is being diagnosed with diabetes. The contribution of chronic kidney disease (CKD) to mortality in Fiji has increased to become the fourth leading cause of death in the country. Fiji Ministry of Health and Medical Services data show that admissions to hospitals for CKD are increasing and treatment of end‐stage kidney disease (ESKD) is a growing burden. Since renal replacement therapy is not readily available or affordable in Fiji, it is advisable to prevent or slow the progression of renal disease to ESKD. Early deduction of renal impairment in diabetic patient is paramount and foremost is to identify proteinuria in the earliest stage. Angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin receptor blockers (ARB) offer reno-protection. These agents reduce proteinuria, a risk marker for renal disease progression.@*Aim@#To evaluate and provide evidence for use ACE-I and ARB in prevention of diabetic nephropathy in our clinical setting.@*Method@#An online search using MESH terms that best answered our research question was conducted on the Medline database. Four seminal papers were identified after shifting through abstracts of 210 studies. These papers were evaluated and conclusions discussed.@*Results@#ACE-I and ARBs are equally reno-protective agents when used individually; it slows the progression of diabetic renal impairment to ESKD and reduces proteinuria to almost normal levels. ARBs are likely to be used as first line agent in patients who have already developed significant diabetic proteinuria since additional blood pressure lowering capabilities of this class of drug may have accentuated benefits. Additionally, ARB’s should be used in patients who cannot tolerate ACE-I induced side effects. For prevention and conversion of diabetic nephropathy to normo-proteinuria; moderate to maximum doses of ACE-I or ARB should be used in clinical practice. Combination of ACE-I plus ARB in management is not recommended. ACE-I still remains the most cost-effective drug for a low resourced clinical setting such as ours.

Abstract This study was designed to investigate the impact of access cavity designs on fracture resistance of endodontically treated maxillary first premolars. The study sample consisted of 72 intact maxillary first premolars, randomly divided into six groups (n = 12). A standardized proximal cavity preparation was prepared for all samples using standard bur. Groups I: control group with only standard proximal cavity and no endodontic access, group II: Truss access cavity, group III: Separated access to buccal and palatal canals without removal of dentine in between, group IV: Access to buccal and palatal canals with removal of dentine in between, group V: Traditional access cavity, group VI: Mesio-occlusal-distal cavity (MOD). For groups I and VI, only composite restoration was used to restore the proximal cavity, while for groups II- V, the access was prepared and endodontic treatment was performed on all teeth, then composite restoration was placed. The root canals were instrumented using nickel-titanium files, irrigated with sodium hypochlorite, and filled with AH plus sealer and gutta-percha using warm vertical condensation. All samples were then placed in an acrylic mold and underwent thermal aging for 10,000 cycles between 5 and 55°C. The samples were fixed in a universal testing machine with the long axis of the roots positioned at 20° to a load applied at a crosshead speed of 1 mm/min using a stainless steel semi-spherical indenter (Ø = 3 mm) until fracture occurred to determine the fracture resistance force in Newton. The normality test (Shapiro-Wilk) showed that data are normally distributed. Group II exhibited the highest mean fracture resistance, and group VI was the least likely to resist the fracture. No statistically significant differences between tested groups (p-value = 0.237). The MOD group showed a more unfavorable mode of fracture compared to other groups. No significant difference in fracture resistance between conservative and traditional access cavities. The missing marginal ridges, such as in MOD cavities played an important role in decreasing the fracture resistance of endodontically treated teeth.
Resumo O objetivo deste estudo foi investigar o impacto do design da cavidade de acesso na resistência à fratura de primeiros pré-molares superiores tratados endodonticamente. MÉTODOS: A amostra do estudo consistiu em 72 primeiros pré-molares superiores intactos, divididos aleatoriamente em seis grupos (n = 12). Um preparo padronizado da cavidade proximal foi realizado para todas as amostras usando broca padrão. Grupos I: grupo de controle com apenas cavidade proximal padrão e sem acesso endodôntico, grupo II: cavidade de acesso Truss, grupo III: acesso separado aos canais vestibular e palatino sem remoção de dentina entre eles, grupo IV: acesso aos canais vestibular e palatino com remoção de dentina entre eles, grupo V: cavidade de acesso tradicional, grupo VI: cavidade mesio-oclusal-distal (MOD). Para os grupos I e VI, apenas a restauração de compósito foi usada para restaurar a cavidade proximal. Já nos grupos II e V, o acesso foi preparado e o tratamento endodôntico foi realizado em todos os dentes e, em seguida, foi colocada a restauração de resina composta. Os canais radiculares foram instrumentados com limas de níquel-titânio, irrigados com hipoclorito de sódio e preenchidos com AH plus sealer e guta-percha usando condensação vertical quente. Todas as amostras foram então colocadas em molde de acrílico e submetidas a envelhecimento térmico por 10.000 ciclos entre 5 e 55°C. As amostras foram fixadas em uma máquina de teste universal com o eixo longo das raízes posicionado a 20° para uma carga aplicada a uma velocidade de cruzeta de 1 mm/min usando indentador semiesférico de aço inoxidável (Ø = 3 mm) até que ocorresse a fratura para determinar a força de resistência à fratura em Newton. RESULTADOS: O teste de normalidade (Shapiro-Wilk) mostrou que os dados são normalmente distribuídos. O grupo II apresentou a maior resistência média à fratura, e o grupo VI foi o menos propenso a resistir à fratura. Não houve diferenças estatisticamente significativas entre os grupos testados (p-valor = 0,237). O grupo MOD apresentou um modo de fratura mais desfavorável em comparação com os outros grupos. CONCLUSÕES: Não houve diferença significativa na resistência à fratura entre as cavidades de acesso conservador e tradicional. A ausência de cristas marginais, como nas cavidades MOD, desempenhou um papel importante na diminuição da resistência à fratura dos dentes tratados endodonticamente.
ABSTRACT
Introduction: African countries are facing an epidemic of cardiovascular diseases. Information on the quality of acute coronary syndrome care offered in underserved communities in Ghana is limited. Using objective criteria, we examined the quality of acute coronary syndrome care offered to patients presenting to a tertiary referral center in Northern Ghana. Methods: we conducted a retrospective review of patients ≥ 18 years old with acute coronary syndrome managed in Tamale Teaching Hospital. We assessed in-hospital outcomes and the extent of compliance to key performance and quality indicators as contained in the 2017 American Heart Association/American College of Cardiology guideline for adults with myocardial infarction. Results: sixty-two (62) patients with a mean age of 56.0 ± 16.1 years were recruited. The median delay to presentation was 24 hours (IQR 15-96 hours). 33.9% had ST-elevation myocardial infarction, of which only 14.3% received reperfusion therapy. About three-quarters of patients received dual antiplatelet therapy at discharge, with fewer patients receiving recommended high-intensity statin therapy (65.5%) or beta-blockers (69.1%). Only 38.2% of patients had their left ventricular ejection fraction documented. No cardiac rehabilitation program existed. Risk stratification of patients with non-ST-elevation myocardial infarction or stress testing for conservatively managed patients was not part of routine practice. Conclusion: acute coronary syndrome management remains a challenging issue in Northern Ghana. Several gaps exist in the care quality, timeliness of interventions and rehabilitation of affected patients. There is an urgent need for measures to improve the delivery of acute coronary syndrome care alongside primary prevention strategies.

No hay diferencia entre la complicación postoperatoria y las tasas de recurrencia en los casos de hernia inguinal operados en condiciones electivas y en condiciones de emergencia. Es más barato que la reparación laparoscópica, el control del dolor de plomo y la falta de dolor neuropático, tiene complicaciones menos testiculares, y es más ventajoso que otros enfoques abiertos
Inguinal hernia is one of the most common urgent problems encountered by surgeons. There were 145 patients treated due to inguinal hernia diagnosis. Out of 44 patients who were operated under emergency conditions. About 131 cases (106 male and 25 female) were treated with unilateral open preperitoneal mesh repair. Patients were examined in terms of postoperative complications. Data collected included as age, gender, medical history, surgery conditions, incarceration and strangulation. There were total of 145 patients included in the study; in which 44 of them (29 male and 15 female, range of age: 30- 72) (group I) were operated under emergency conditions and 101 of them (51 male and 50 female, range of age: 25-78) (group II) were operated under elective conditions. There was comorbidity in 31 patients of group I and 77 patients of group II. About 47.7% (n=21) of cases who underwent emergent surgery due to incarceration, while 43.6% (n=44) of cases who were operated under elective conditions. There were 12 femoral hernias in group I and 19 femoral hernia in group II. There is no difference between postoperative complication and recurrence rates in inguinal hernia cases operated under elective conditions and under emergency conditions. It is cheaper than laparoscopic repair, lead pain control and lack of neuropathic pain, has less testicular complications, and it is more advantageous than other open approaches.

La dermatitis herpetiforme es una enfermedad autoinmune que se caracteriza por la presencia de lesiones vesiculares y prurito en la superficie extensora de las extremidades, nalgas y parte baja de la espalda. Se presenta el caso clínico de una mujer de 21 años, natural y procedente de Iquitos, que presentó múltiples vesículas dolorosas, pruriginosas, de base eritematosa y purulentas en ambos codos durante un mes. Posteriormente, estas lesiones se diseminaron a ambas rodillas y se agregó prurito intenso. La paciente experimentó períodos alternantes de remisión y exacerbación. La correlación del cuadro clínico, resultados serológicos y de biopsia, junto con respuesta terapéutica a la dapsona confirmaron el diagnóstico de dermatitis herpetiforme, con una evolución favorable y remisión de la enfermedad.
Dermatitis herpetiforme is an autoimmune disease characterized by the presence of vesicular lesions and itching on the extensor surface of the limbs, buttocks, and lower back. The clinical case of a 21-year-old woman, a native of and from Iquitos, is presented. She presented multiple painful, itchy vesicles with an erythematous and purulent base on both elbows for a month. Subsequently, these lesions spread to both knees, and intense itching was added. The patient experienced alternating periods of remission and exacerbation. The correlation of the clinical picture, serological and biopsy results, along with the therapeutic response to dapsona, confirmed the diagnosis of dermatitis herpetiforme, with a favorable evolution and remission of the disease.
ABSTRACT
During the last few decades, the field of rehabilitation has experienced substantial development, growth, and acceptance. Rehabilitation addresses the impact of a health condition on a person's everyday life by optimizing their functioning and reducing their experience of disability. Rehabilitation expands the focus of health beyond preventative and curative care to ensure people with a health condition can remain as independent as possible and participate in education, work, and meaningful life roles.1 A definition of rehabilitation for research purposes has been recently published.2 Scientific and clinical research have generated a body of knowledge that strongly supports the use of many rehabilitation interventions with positive outcomes in various populations and health conditions.
ABSTRACT
Objective: to evaluate the lifestyle and eating habits of bank workers in Mozambique. Method: a cross-sectional study with a quantitative approach, with 32 employees from three bank branches, selected through convenience sampling, in 2021. A food frequency questionnaire and a lifestyle questionnaire were applied. Descriptive statistics were employed for data treatment using SPSS v.25, presenting the data as absolute and relative frequencies. Results: in terms of lifestyle, 65.6% of participants were physically active, 100% were non-smokers, and 40.6% preferred fruits and vegetables instead of sweet and savory foods. Regarding food consumption frequency, the bread and equivalents group had the highest daily intake, with French bread (44%) being the most consumed, followed by the fruit and vegetable group with lettuce leading consumption (44%). The third group was meat and equivalents with the most consumed food in that category being fried egg (28%). The least consumed food group was oils and sauces with the most consumed in the category being salad dressings (19%). Conclusion: more healthy lifestyles and eating habits were evidenced.

PROSPECTIVE STUDY ON ACUTE MESENTRIC ISCHEMIA AT A TERTIARY CARE CENTRE Original Research Paper Dr Seema Math Assistant professor, Hepatopancreatico biliary Surgeon, Department of General Surgery, AMCH Vijayapur. X 1GJRA - GLOBAL JOURNAL FOR RESEARCH ANALYSIS Background: Mesenteric ischemia develops when your small intestine's blood supply is restricted by narrowed or blocked arteries. The small intestine might suffer severe damage from decreased blood supply. A blood clot that suddenly cuts off the small intestine's blood supply (acute mesenteric ischemia) necessitates emergency surgery. Angioplasty or open surgeries are options for treating chronic mesenteric ischemia. In this study, predictive factors for mesenteric vascular disorders are assessed, with a focus on mesenteric ischemia. All the consecutive Methods: cases of Acute abdomen who were diagnosed & treated for acute mesenteric ischemia in the Department of emergency & surgical gastroenterology at Al Ameen Medical Collage and Hospital from July 2021 to Jan 2023 were included in the study. NOMI and low ow / perfusion states were excluded from the study. There were 20 patients of acute mesenteric Results: ischemia, of which 17 were males and 3 were female. 12 patients had acute mesenteric ischemia who had under gone surgical management & follow up medication, 5 on medical management with follow up medication & 3 expired. 18 out of 20 patients had risk factors mesenteric thrombosis. 14 required ICU stay, 12 required surgical management, 8 out 20, had undergone stoma reversal after 6 to 8 weeks at the later date. 4 of them had re-admission for dehydration and dyselectrolytemia, TPN and ICU admission .2 patient had just D LAP & then explored where in segment of the bowel was dusky and congested settled with 100% O2 & warm saline but he was admitted with chest infection and ARF needing with ICU stay and dialysis. Duration of Hospital stay varied from 1 to 30 days with mean of 15 days in mesenteric vascular diseases. Average incidence of AMI is 18 out of 95 Patients over period of 18 months (8.2%in one year). AMI is an uncommon but life-threatening vascular Conclusions: emergency that requires immediate diagnosis and urgent treatment that is more surgical than medical, or in some circumstances, IR guided
ABSTRACT
Aim of the study: The present study aimed to study histological features of different organs before and after treatment of diabetes by using avocado extract in rats. Materials and methods: Hot aqueous extraction of avocado was performed. Forty male rats (weighted 140–190g) were used in this study. Following the time of acclimatization, the animals had an overnight fast of 18 hours before being prepped for alloxan monohydrate-induced diabetes. Before and after induction, measurements of the animals’ body weights and blood glucose levels were made. However, rats received an IP injection of alloxan 150 mg/kg bw. Following that, the rats’ blood glucose levels were tracked every day for 3 weeks to establish a stable levels of blood glucose. The animals were divided into 4 groups: Group 1 got water as a non-induced (negative control) condition. Alloxan-induced rats in Group 2 received water as a positive control. Group 3: Alloxan-induced and aqueous extract-treated animals and Group 4 was only given a 40 g/L dose of the aqueous extract of avocado. Pancreas, livers, as well as kidneys from control, alloxanized, and treated rats were taken at different times, processed and utilized for histological examination after being preserved in 10% formaldehyde till processing and staining. Results: The current results showed a significant difference between different groups especially in G3 at different weeks. However, rats in G2 exhibited depleted islet cells and regions of cell necrosis. The tiny, preserved islet cells (PIL) in diabetic rats treated with extract after 1 week (G3) were an improvement as compared with rats at G2. As the days advanced, more improvements were seen in the pancreatic architecture of the rats treated with extract, including the presence of more noticeable islet cells and exocrine cells. As seen by the intact pancreatic islet in G3, caused the healing of the pancreatic tissue after 3 weeks of treatment by extracts. Alloxanized rats (G2) showed the presence of cell necrosis as well as infiltrations of inflammatory cells. However, as the course of therapy continued, it became clear that the tissue architecture had improved, and more glomeruli were seen as well as fewer inflammatory cells (G3). Livers of rats in (G2) showed visible cell necrosis, when compared to the histology of G1 and G4. After receiving medication, rats in group G3 had compact, healthy liver tissues after three weeks. In conclusion, the pancreas, kidneys, and liver were all protected by the avocado extract and showed enhancement in the histological architecture and glucose levels.
