Fulltext The physiology of leptin: revisited

Singh, Harbindar Jeet

Medical Health Reviews, 2009;2009(1):95-133.
MyJurnal

Leptin, a 167 amino-acid product of the ob or LEP gene, was first reported in 1994 after a 40-year search that began following the emergence of a mutant strain of mice with hyperphagia, early on-set obesity, and delayed sexual maturation. Since then, leptin deficiency has also been reported in the rat, and more recently in humans. It is secreted constitutively primarily by the white adipose tissue, and in smaller quantities by a number of non-adipose tissues. It acts by binding to specific membrane bound leptin receptors, belonging to the class 1 cytokine receptor family, and activating the JAK-STAT system. Leptin regulates appetite and body weight mainly through its actions on the hypothalamus involving the NPYmelanocortin pathway, and, to a lesser extent, through increased energy expenditure by way of sympathoactivation and increased substrate cycling. Its effects on reproduction, puberty in particular, are mediated through actions on the hypothalamic-pituitary-gonadal axis and on the gonads. Leptin also appears to have permissive roles in CNS development during the neonatal period, bone growth and development, and in haemopoietic and immune functions. Although it was its deficiency state that first led to its discovery, it now appears that the clinical significance of leptin lies not only in the consequences of its deficiency but also when it is in excess as occurs in obesity. Emerging evidence is implicating leptin as a link between obesity associated cardiovascular disease risks and infertility. Besides this, leptin is also being implicated as a growth factor in cancer. The story that started with a search for a body weight regulating factor is now unfolding into one that is revealing roles for leptin that stretch beyond the regulation of appetite and body weight.

Piper Betle L. (PB) belongs to the Piperaceae family. The presence of a fairly large quantity of diastase in the betel leaf is deemed to play an important role in starch digestion and calls for the study of weight loss activities and metabolite profile from PB leaf extracts using metabolomics approach to be performed. PB dried leaves were extracted with 70% ethanol and the extracts were subjected to five groups of rats fed with high fat (HF) and standard diet (SD). They were then fed with the extracts in two doses and compared with a negative control group given water only according to the study protocol. The body weights and food intakes were monitored every week. At the end of the study, blood serum of the experimental animal was analysed to determine the biochemical and metabolite changes. PB treated group demonstrated inhibition of body weight gain without showing an effect on the food intake. In serum bioassay, the PB treated group (HF/PB (100mg/kg and 500mg/kg) showed an increased in glucose and cholesterol levels compared to the Standard Diet (SD/WTR) group, a decrease in LDL level and increase in HDL level when compared with High Fat Diet (HF/WTR) group. For metabolite analysis, two separation models were made to determine the metabolite changes via group activities. The best separation of PCA serum in Model 1 and 2 was achieved in principle component 1 and principle component 2. SUS-Plot model showed that HF group was characterized by high-level of glucose, glycine and alanine. Increase in the β-hydroxybutyrate level similar with SD group animals was evident in the HF/PB(500mg/kg) group. This finding suggested that the administration of 500mg/kg PB extracts leads to increase in oxidation process in the body thus maintaining the body weight and without giving an effect on the appetite even though HF was continuously consumed by the animals until the end of the studies and also a reduction in food intake, thus maintaining their body weight although they were continuously consumed HF.

Leukaemic stem cells have heterogenous differentiation potential. The immunophenotypes of blast cells are usually consistent throughout the disease course even at relapse. Rarely, blast cells may undergo a ‘lineage switch’ during the course of disease especially during relapse. We would like to highlight such a case in a 10- year old boy who presented with a two weeks history of lethargy, poor appetite, low grade fever, respiratory distress, cardiac failure, generalized oedema and hepatosplenomegaly. Full blood count showed a leucocyte count of 41.5x10 9 /L and platelet count of 37x10 9 /L. The peripheral blood film showed presence of numerous blast cells. Bone marrow aspiration revealed a hypercellular marrow, which consisted of mainly blast cells with high nuclear to cytoplasmic ratio and inconspicuous nucleoli. Immunophenotyping and cytochemistry results were consistent with the diagnosis of Tcell acute lymphoblastic leukaemia. The patient achieved remission after treatment with UK ALL 97 protocol, regime B chemotherapy. However, he relapsed seven months after the initial diagnosis with 26% blast cells in the bone marrow aspirate. The majority was L1 blast cells admixed with some L2 blast cells. Immunophenotyping was consistent with common precursor B acute lymphoblastic leukaemia. The treatment was changed to a more lineage specific chemotherapy. Nonetheless, the patient never achieved remission and was planned for palliative management. This case illustrated a unique and rare case of rapid lineage switch from T-cell acute lymphoblastic leukaemia to common precursor B-cell acute lymphoblastic leukaemia.

Poor appetite and inadequate food intake together with depression are associated with malnutrition, that will increase risk of morbidity and mortality among elderly people. Identifying factors associated with these conditions are essential for formulation of preventive strategies. Therefore, a study was conducted to identify factors associated with poor appetite and depression among institutionalised Chinese elderly people in Butterworth, Penang. A total of 100 Chinese elderly (49 men and 51 women) aged 60 years and above, (mean age ± SD of 74.7 ± 9.2 years), with no known terminal and mental illnesses from two nursing homes participated in this study. Subjects were interviewed to gather information on appetite using Council of Nutrition Appetite Questionnaire (CNAQ), depression using Geriatric Depression Scale (GDS) and also socio demographic and health status. Food intake was assessed using a combination of one-day food weighing and 24 hour diet recall. Body weight and height were measured. Results showed that the mean energy and nutrients intake did not achieve the Recommended Nutrient Intake of Malaysia (RNI), with the exception for vitamin C. Only 4% of the subjects were underweight and obese, 65% normal and 31% overweight. A total of 70% and 73% of subjects had poor appetite and depression, respectively. Subjects who had depression (adjusted OR = 2.78, 95% CI = 0.95-8.03), energy intake below RNI (adjusted OR = 2.34, 95% CI = 0.68-6.95) and difficulty to fall asleep at night (insomnia) (adjusted OR = 2.22, 95% CI = 0.72-6.82) were more likely to have poor appetite. Subjects who had poor appetite (adjusted OR = 3.36, 95% CI = 1.19-9.47) and insomnia (adjusted OR = 2.58, 95% CI = 0.83-7.98) were more likely to have depression. In conclusion, although the majority of subjects had normal body weight but the nutrient intake was inadequate. Poor appetite and depression were prevalent and interrelated and also strongly associated with insomnia.

On December 26, 2004, an earthquake triggered a devastating tsunami that caused death and destruction in twelve countries including India, Indonesia, Malaysia, Maldives, Seychelles, Somalia, Sri Lanka and Thailand. One of the authors was a volunteer with FELDA WAJA AMAN MALAYSIA medical relief team that served the Aceh victims from 16th February to 24th February 2005 (8 weeks post tsunami). A study to determine the pattern of health ailments was conducted among children aged 18 years and below based at Seuneubok Camp, 30 km from Banda Aceh. All respondents were from Pulau Aceh and the total number of children seen and examined was 60. About 18% had lost their fathers, 10 % had lost their mothers and 27% had lost one or more of their siblings. 77% suffered some form of health ailments. The common health ailments were diarrhea (61%), respiratory complaints (59%) and fever (20%). About 38 % of preschoolers had loss of appetite and 28% had sleep disturbances. About 35% of the elementary school children suffered from sleep disturbances, 29% of the young adolescents suffered from headaches and 24% had sleep disturbances. Nearly a quarter (24%) of all the children felt fearful and anxious about the disaster. Nevertheless, 56% of the respondents wanted to return back to Pulau Aceh, although 14 % did not want to go back. Interestingly, 73% of the children voiced their gratitude to God for having been saved from death.

MyJurnal

The pandemic of obesity is of great concern as its associated co-morbidities are devastating; causing lifelong burden to individual’s health and is economically costly to a country. Factors that lead to obesity are a combination of environmental and genetic factors. The Pro-opiomelanocortin (POMC) gene resides in chromosome 2p23.3, and its protein is composed of 241 amino acids which is responsible for the production of polyhormones that regulate appetite and food intake. The study aimed to investigate the prevalence of the RsaI single nucleotide polymorphism (SNP) site in the 5’-untranslated region (UTR) of POMC and its possible association with obesity among 302 multi-ethnic Malaysian subjects (142 obese, 160 non-obese; 120 males, 182 females) from the Kampar Health Clinic. Subjects were recruited by convenience sampling with informed consent and socio-demographic data as well as anthropometric measurements were taken. Subjects were genotyped by polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) analysis using DNA extracted from blood. The distribution of the RsaI genotypes was significantly different among the different ethnicities, but the mutated RsaI (- / -) genotype was rare as it only occurred in 8.9% of the subjects. With the frequency of the RsaI (-) allele of 0.31, it was associated with the percentage of skeletal muscles (p

PMID: 25606297 MyJurnal

A 30-year-old Iban woman presented to a rural primary healthcare clinic located along the Batang Rejang in Sarawak. She had a 2-day history of rash, which started over her trunk and later spread to her face and limbs. What started out as individual erythematous maculopapular spots later coalesced to form larger raised blotches. The rash was extremely pruritic and affected her sleep, and hence her visit. The rash was preceded by high grade, persistent fever that was temporarily relieved by paracetamol. She also complained of malaise, arthralgia and myalgia. Her appetite had been poor since the onset of the fever. She lived in a long house at the edge of the jungle. Although she did not have a history of going into the jungle to forage, she went regularly to the river to wash clothes. Clinically, she appeared lethargic and had bilateral conjunctival injection. Her left anterior cervical lymph nodes were palpable. There were erythematous macules measuring 5 to 15 mm distributed over her whole body but predominantly over the chest and abdominal region (Figure 1). An unusual skin lesion was discovered at the right hypochondriac region. This lesion resembled a cigarette burn with a necrotic centre (Figure 2). There was no evidence of hepato-splenomegaly. Examination of the other systems was unremarkable. On further questioning, the patient admitted being bitten by a ‘kutu babi’ or mite 3 days before the onset of her fever.

Background: This paper investigates the quality of life of brain pathology patients in relation to their sociodemographic
profiles and clinical factors.

Methods: This is a cross-sectional study done at a tertiary referral hospital in Kuala Lumpur. A total of 100
patients were recruited in the study after excluding 22 patients who did not met the exclusion criteria. The
European Organisation for Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30) self-administered
questionnaire was utilized in the study. The Global health status/QoL, Physical functioning, Role functioning,
Emotional functioning, Cognitive functioning, Social functioning, Fatigue, Nausea and vomiting, Pain, Dyspnoea,
Insomnia, Appetite loss, Constipation, Diarrhoea, and Financial difficulties were assessed in this study.

Results: The most severe impairment in functioning was with lowest score of cognitive functioning (mean
score=61) and the most severe symptom was fatigue (mean score=45). There were significant differences in
quality of life scores in different socio-demographic groupsand types of brain pathology patients. Patients aged
below 40 years old or less had better physical functioning, less symptoms of fatigue and insomnia compared
to patients who were more than 40 years old. Male patients faced more financial difficulties compared with
female patients. Patients who were married had increased insomnia compared to the single patients. Employed
patients had better physical functioning and less financial difficulties compared with patients who were
unemployed. Patients who earned >RM 2500.00 monthly had better physical functioning, less symptoms of pain and less financial difficulties than patients who earned ≤RM 2500.00. Patients with qualifications lower
than SPM tended to face more financial difficulties compared to patients with qualifications of SPM or higher.
Meningioma patients had better social functioning compared with others, whereas Carvenoma patients had
better physical functioning. Meningioma patients had more symptoms of insomnia compared with other
patients. All the findings were with p value less than 0.05.

Conclusion: The quality of life of patients with brain pathology is affected by socio-demographic factors and
clinical diagnoses. Efforts should be made to improve the overall quality of life of these patients.

Fulltext Effect of Sequence of Fruit Intake in a Meal on Satiety

Abdul Hakim BN, Yahya HM, Shahar S, Abdul Manaf Z, Damanhuri H

Int J Environ Res Public Health, 2019 11 13;16(22).
PMID: 31766283 DOI: 10.3390/ijerph16224464

Little is known about the effects of manipulating sequence of fruit consumption during a meal in suppressing an individual's appetite. Therefore, we investigate the effects of the sequence of fruit intake on satiety and blood glucose in a group of 17 healthy, young male adults. This intervention study repeatedly measured the effects of fruit intake (120 g red apple) before and after a meal and control (no fruit). Ad libitum test meal was weighed before and after a meal. Subjective appetite rating and appetite-related hormones were assessed at regular time intervals. The satiety score was significantly higher for fruit intake before a meal followed by after a meal and control (p < 0.05). Eating fruit before a meal reduced 18.5% (166 kcal) subsequent energy intake compared to control (p < 0.05). Fruit intake before a meal had a significantly higher incremental area under the curve (iAUC) of Glucagon-like peptide 1 (GLP-1), compared to after a meal (p < 0.05). There were no differences in plasma changes of ghrelin, Cholecystokinin 8 (CCK8), or blood glucose in all sessions. Consuming fruit before a meal potentially enhanced satiety. Further research is required to confirm both short- and long-term effects of the sequence of fruit intake on appetite regulation in a wider population.

J Ultrason, 2018;18(75):365-368.
PMID: 30763024 DOI: 10.15557/JoU.2018.0054

A 53-year-old woman presented with left-sided abdominal pain, nausea and vomiting for the past 3 months with associated loss of appetite and weight. On physical examination, there was a large, ill-defined, firm mass at the epigastrium. Ultrasonography showed heterogeneously hypoechoic filling defect within the dilated main portal vein. The filling defect showed florid signals on Doppler mode and it appeared to be an extension of a larger periportal mass. Contrast enhanced abdominal computed tomography confirmed a large distal gastric mass infiltrating into the periportal structures, including the main portal vein and the splenic vein. Esophagogastroduodenoscopy performed 2 days later showed an irregular, exophytic mass extending from the antrum into the first part of duodenum. The mass was deemed inoperable. Histopathological examination showed gastric adenocarcinoma. She was started on anticoagulant, chemotherapy and pain management. Follow-up computed tomography 4 months later showed liver metastases and formation of collateral blood vessels.

Fulltext Nutrition and ecosystems in Sarawak: The role of the areca nut

Strickland SS, Duffield AE

Asia Pac J Clin Nutr, 1998 Dec;7(3/4):300-6.
PMID: 24393688

The effects of population pressure on agricultural sustainability in the delicate tropical and subtropical ecosystems have often been thought to explain high prevalence rates of malnutrition in rural South-East Asia. However, recent studies in rural Sarawak suggest that processes of modernisation have resulted in increased variations in energy nutritional status in adults. A contributory factor may be consumption of the areca nut (Malay pinang, of the palm Areca catechu). This is thought to influence energy balance through effects on appetite and resting metabolic rate. Body mass index (BMI, kg/m2) data for 325 Iban men and 438 non-pregnant Iban women, measured in 1990 and again in 1996, have been analysed in relation to areca use, smoking behaviour, socio-economic status, and reported morbidity. Body composition derived from skinfold thickness measurements for 313 men and 382 women was also analysed. The results suggest that use of areca nut is associated with significantly lower age-related increments in BMI and percentage body fat in women after allowing for age, smoking, reported morbidity, and confounding socio-economic factors. Therefore, the impact of recent economic and social development seen in rising prevalences of 'over-nutrition' may be modulated by use of the areca nut.

Case Rep Ophthalmol Med, 2012;2012:606741.
PMID: 22611511 DOI: 10.1155/2012/606741

A 23-year-old Malay man presented with headache for one-month duration. It was associated with painless blurring of vision of the right eye. He had loss of appetite and reduced weight but no night sweats or hemoptysis. His visual acuity on the right eye was 6/45 and improved to 6/15 with pinhole. Right fundus examination revealed a choroidal tuberculoma located at one disc diameter away from optic disc superiorly with mild vitritis. Systemic examinations revealed no significant finding. Mantoux test reading was 22 mm with erythrocyte sedimentation rate that was 14 mm/h. Other blood investigations were negative with normal chest radiography. The computerized tomography scan of the brain revealed multiple cerebral abscesses. A clinical diagnosis of right ocular tuberculosis with multiple cerebral abscesses was made. He was treated with antituberculosis chemotherapy for one year which divided into intensive phase for three months and maintenance phase for nine months. Cerebral abscesses resolved after three months of antituberculosis drugs and at one-year follow-up, and the choroidal tuberculoma resolved completely with scar formation and significant macular striae.

Fulltext Beta-human Chorionic Gonadotropin-secreting Lung Adenocarcinoma

Wong YP, Tan GC, Aziz S, Pongprakyun S, Ismail F

Malays J Med Sci, 2015 Jul-Aug;22(4):76-80.
PMID: 26715912 MyJurnal

Overexpression of beta-human chorionic gonadotropin (β-hCG) is frequently associated with germ cell tumours, especially choriocarcinoma. Ectopic secretion of β-hCG by non-small cell lung cancer is exceptional. We present an exceedingly rare case of pulmonary adenocarcinoma that secretes β-hCG. Our patient is a 62-year-old postmenopausal woman, a nonsmoker, who presented with a six-month history of progressive dyspnoea, associated with decreased appetite and significant weight loss. Her serum β-hCG was very high (11211.9 mIU/ml), which prompted investigations to exclude germ cell tumour. Radiological imaging revealed a 10-cm right lung mass with adrenal metastasis. No other focal lesions were detected. Microscopy of the lung biopsy specimen showed replacement of normal lung tissue by sheets of malignant cells, forming vague glands in some areas. Immunohistochemically, the malignant cells showed focal immunopositivity for thyroid transcription factor 1 (TTF-1), napsin A, cytokeratin 7 (CK7) and β-hCG. A diagnosis of β-hCG-secreting pulmonary poorly differentiated adenocarcinoma was rendered. Serum β-hCG level decreased significantly to 168.6 mIU/ml after the first cycle of chemotherapy. In conclusion, β-hCG expression in lung cancer should be recognised to facilitate prompt diagnosis and initiation of appropriate intervention.

Fulltext Prevalence and Predictors of Malnutrition Risk among Post-Stroke Patients in Outpatient Setting: A Cross-Sectional Study

Wong HJ, Harith S, Lua PL, Ibrahim KA

Malays J Med Sci, 2020 Jul;27(4):72-84.
PMID: 32863747 MyJurnal DOI: 10.21315/mjms2020.27.4.7

Background: The present study examined the prevalence and predictors of malnutrition risk among post-stroke patients.
Methods: Post-stroke patients who attended the outpatient clinics in three hospitals of Peninsular Malaysia were enrolled in the study. The risk of malnutrition was assessed using the Malnutrition Risk Screening Tool-Hospital. Data including demographic characteristics, clinical profiles, dietary nutrients intake, body mass index (BMI) and hand grip strength were collected during the survey. The crude odds ratio (OR) and adjusted odds ratio (AOR) were reported for univariate and multivariate logistic regression analyses, respectively.
Results: Among 398 patients included in the study, 40% were classified as high-risk for malnutrition. In the multivariable logistic regression, tube feeding (AOR: 13.16, 95% confidence interval [CI]: 3.22-53.77), loss of appetite (AOR: 8.15, 95% CI: 4.71-14.12), unemployment (AOR: 4.26, 95% CI: 1.64-11.12), wheelchair-bound (AOR: 2.23, 95% CI: 1.22-4.09) and BMI (AOR: 0.87, 95% CI: 0.82-0.93) were found to be significant predictors of malnutrition risk among stroke patients.
Conclusion: The risk of malnutrition is highly prevalent among post-stroke patients. Routine nutritional screening, identification of risk factors, and continuous monitoring of dietary intake and nutritional status are highly recommended even after the stroke patient is discharged.

Development of an Immunodiagnostic Test for Screening Human Brucellosis Cases Using the Whole-Cell Antigens of Brucella abortus

Bhartiya NM, Husain AA, Daginawala HF, Singh L, Kashyap RS

Malays J Med Sci, 2020 Dec;27(6):15-26.
PMID: 33447131 DOI: 10.21315/mjms2020.27.6.3

Background: Human brucellosis is an important zoonotic disease of public health and often remains neglected owing to lack of sensitive and efficient diagnostic methods. This study evaluates diagnostic utility of in-house designed enzyme-linked immunosorbent assay (ELISA) using whole-cell antigens of Brucella abortus (B. abortus) S19 against the commercially available kits.
Methods: A prospective cohort study involving different populations within the Vidarbha regions of Maharashtra, India was conducted through camps organised from May 2009 to October 2015. A total of 568 serum samples were collected from high-risk people recruited as study cohorts based on inclusion criteria, additional risk factors and clinical symptoms. Samples were evaluated by indirect ELISA using the whole-cell antigens of B. abortus. The results were compared with the commercially available IgG detection ELISA kit to ascertain the specificity and sensitivity of the developed test.
Results: Fever, body ache, joint pain, lower back pain, loss of appetite and weight loss were major symptoms associated with the disease. With the cut-off of > 0.8, the positivity of brucellosis infection was at 12.32% (70/568) compared to 9.33% (53/568) as detected by the commercial kit. The in-house developed ELISA method yielded a sensitivity of 87.5% and specificity of 99.18% as compared to the commercial kits (sensitivity -80.30% and specificity -99.6%).
Discussion: The B. abortus S19-derived whole-cell protein-based ELISA is rapid and cost-effective and can be used for screening brucellosis infection in lieu of the commercially available ELISA kits.

PMID: 24800385 MyJurnal

INTRODUCTION: Malnutrition is a common phenomenon among the elderly and quite often related to psychosocial problems. The objective of this study was to determine malnutrition risk and its association with appetite, functional and psychosocial status among elderly Malays in an agricultural settlement, i.e. FELDA Sungai Tengi, Selangor.
METHODS: A cross-sectional study was conducted among 160 subjects (men = 36.2%), with a mean age of 65.0 +/- 3.9 years, who were interviewed to obtain information on malnutrition risk and appetite using Mini Nutritional Assessment Short Form and Simplified Nutritional Appetite Questionnaire, respectively. Functional status was determined using Instrumental Activities of Daily Living (IADL), Elderly Mobility Scale (EMS) and handgrip strength. Mini Mental Status Examination (MMSE), Geriatric Depression Scale and De Jong Gierveld Loneliness Scale were used to identify cognitive impairment, depressive symptoms and loneliness status of subjects respectively. A total of 42.5% of subjects were at risk of malnutrition and 61.2% had poor appetite. The mean scores of IADL and EMS were lower in subjects at risk of malnutrition, compared to those who were not at high risk (p < 0.05 for both parameters). Multiple linear regression showed that 19.8% of malnutrition risk was predicted by poor appetite, decreased functional status (IADL) and depression.
CONCLUSION: Malnutrition risk was prevalent and associated with poor appetite, functional status and psychosocial problems among the elderly subjects. The psychosocial aspect should also be incorporated in nutrition intervention programmes in order to improve mental well-being and functional independancy.

A cichlid fish, the Nile tilapia (Oreochromis niloticus), is a maternal mouthbrooder, which exhibits minimum energy expenditure and slower ovarian cycles during mouthbrooding. The objective of this study was to observe changes in the gene expression of key neuropeptides involved in the control of appetite and reproduction, including neuropeptide Y a (NPYa), reproductive neuropeptides: gonadotropin-releasing hormone (GnRH1, GnRH2 and GnRH3) and kisspeptin (Kiss2) during mouthbrooding (4- and 12-days), 12-days of food restriction and 12-days of food restriction followed by refeeding. The food restriction regime showed a significant increase in npya mRNA levels in the telencephalon. However, there were no significant alterations in npya mRNA levels during mouthbrooding. gnrh1 mRNA levels were significantly lower in mouthbrooding female as compared with females with food restriction. gnrh3 mRNA levels were also significantly lower in female with 12-days of mouthbrooding, 12-days of food restriction followed by 12-days of refeeding when compared with controls. There were no significant differences in gnrh2 and kiss2 mRNA levels between groups under different feeding regimes. No significant changes were observed in mRNA levels of receptors for peripheral metabolic signaling molecules: ghrelin (GHS-R1a and GHS-R1b) and leptin (Lep-R). These results suggested that unaffected npya mRNA levels in the telencephalon might contribute to suppression of appetite in mouthbrooding female tilapia. Furthermore, lower gnrh1 and gnrh3 mRNA levels may influence the suppression of reproductive functions such as progression of ovarian cycle and reproductive behaviours, while GnRH2 and Kiss2 may not play a significant roles in reproduction under food restriction condition.
