Objectives:
To compare mean basal metabolic rate (BMR) estimated using Harris-Benedict equation (HB) and Bioelectrical Impedance Analysis (BIA) and the BMR measured using Indirect Calorimetry (IC) among adult obese Filipino patients with prediabetes or type 2 diabetes mellitus (T2DM).
Methodology:
This was a multi-center, cross-sectional study based on review of outpatient medical records of adult, obese Filipino patients with pre-diabetes or type 2 diabetes mellitus who were seen prior to weight loss intervention at the Outpatient Clinic of St. Luke’s Medical Center-Quezon City and the Metabolic and Diabetes Center of Providence Hospital from August 2017 to January 2018. BMR was derived using three methods: Harris-Benedict equation, Bioelectrical Impedance Analysis and Indirect Calorimetry.
Results:
A total of 153 subjects were included in the study. Eighty subjects (52%) have pre-diabetes while 73 subjects (48%) were diagnosed with T2DM. The mean BMR measured using IC is 1299±252 kcal/day while estimated mean BMR predicted using HB equation and BIA were 1628±251 kcal/day and 1635±260 kcal/day, respectively. Compared to measurement by IC, HBE and BIA significantly overestimated the mean BMR by 329 and 336 kcal/day, respectively (p-value=<0.0001). IC measured BMR showed strong positive correlation with weight and moderate positive correlation with height. Multiple stepwise regression analysis yielded the BMR prediction equation: BMR (kcal/day) = -780.806 + (11.108 x weight in kg) + (7.164 x height in cm).
Conclusion
Among obese Filipinos with T2DM or prediabetes, HB equation and BIA tend to overestimate the BMR measured using IC.

2.Polycystic ovarian syndrome- metabolic aspects
Journal of Medical Research 2005;37(4):77-80
Polycystic ovarian syndrome (PCOS) was not considered as a simple disease at ovary but as a metabolic syndrome. The centre of this process is the disturbance of gonadotropin and metabolism of insulin/insulin-like growth factor 1 (IGF1). Some main symptoms: mentruation disorder, hyperandrogenaemia, obesity and hyperresistant to peripheral insulin with hyperinsulinaemia. For those patients have symptoms on skin, the local treatment is provided, other systemic treatments were used for those have metabolic diseases. Women with polycystic ovarian syndrome often are obesity. Metformin lose weight, regulate menstruation circle and increase significantly ovulation. Reducing androgen concentration can improve the symptom of acne and hypertrichosis. Infertile treatment, metformin can be effect in stimulating ovaries by clomiphen or FSH, increase the rate of having pregancy and reduce the rate of miscarriage in women with PCOS.

BACKGROUND: Various methods and equations are available to predict the basal metabolic rate (BMR). A published study comparing the Harris-Benedict Equation, Bioelectrical Impedance Analysis, and Indirect Calorimetry (IC), was done among Filipinos, and was able to obtain a novel formula for BMR. The purpose of this study is to validate this novel formula.
METHODS: This is a multi-center, cross-sectional, validation study of the novel BMR equation, done among adult overweight and obese Filipinos, who were seen at St. Luke’s Medical Center and Providence Hospital in Quezon City, Outpatient Clinics from August 2019 to March 2020. Purposive sampling was done, and upon giving consent, subjects had undergone interview, anthropometrics measurement, and IC.
RESULTS: 174 samples were enrolled. Mean age is 43 years old, majority are females. 27% have no co-morbidities; of those with co-morbidities, half have diabetes mellitus (DM). Mean weight is 74.30 kg; mean BMI is 29.78 kg/m2 . The mean computed BMR is 1174.70 kcal/day, which is 145.83 significantly lower than the BMR derived with calorimetry: 1320.53 kcal/day (P-value 0.000). However, the scatterplot reveals the linearity of positive direction for both values. 31% of the computed BMR fell within the +/-10% estimate of the actual BMR. Stratification of the results between those with DM and without, lowered the difference between the calculated and actual BMR to 46 kcal/day (from 145.83) among the DM subgroup, and increased the estimated accuracy to 38% falling within the +/- 10% estimate of the actual values.
CONCLUSION: The novel BMR formula is linearly reflective of the basal metabolism of adult overweight and obese Filipinos, but the numerical values are lower compared to actual calorimetry results, yielding more accuracy when applied among patients with diabetes.

Basal metabolic rate (BMR) is of great significance to the setting of daily energy requirements and the scientific diet guidance for the population. There are 3 kinds of measurement methods for BMR, including the direct calorimetry, the indirect calorimetry, and the equation estimation. The direct calorimetry method is difficult to implement and is only used in some special populations. The indirect calorimetry and the equation estimation are two methods that are currently used commonly. The indirect calorimetry is highly accurate and suitable for individual for basal metabolic measurement or datum collection via equation estimation. The equation estimation is simple and convenient, which is suitable for large samples.

5.Research advances in the pathogenesis and treatment of neurodegeneration with brain iron accumulation.
Chinese Journal of Contemporary Pediatrics 2021;23(6):650-656
Neurodegeneration with brain iron accumulation (NBIA) is a group of rare neurogenetic degenerative diseases caused by genetic mutations and characterized by iron deposition in the central nervous system, especially in the basal ganglia, with an overall incidence rate of 2/1 000 000-3/1 000 000. Major clinical manifestations are extrapyramidal symptoms. This disease is presently classified into 14 different subtypes based on different pathogenic genes, and its pathogenesis and treatment remain unclear. This article summarizes the research advances in the pathogenesis and treatment of NBIA, so as to help pediatricians understand this disease and provide a reference for subsequent research on treatment.

OBJECTIVETo measure the energy expenditure of reading and watching TV for young women.
METHODSAll 30 girls in the college were selected according to questionnaire, medical examination, blood test, liver function and thyroid gland level. Energy expenditure of reading and watching TV was measured respectively by the Cosmid K4b2 portable gas analysis system from Italy. Basic metabolic rate (BMR) and resting metabolic rate (RMR) were measured as to analyzing results conveniently.
RESULTSThe energy expenditure in reading was (226.35 +/- 56.07) kJ/h and the heart rate was (69 +/- 5) bmp. For watching TV it was (220.79 +/- 65.69) kJ/h and the heart rate was (68 +/- 5) bmp. BMR was (178.53 +/- 53.51) kJ/h and the heart rate was (62 +/- 6) bmp. RMR was (214.76 +/- 44.56) kJ/h and the heart rate was (65 +/- 6) bpm.
CONCLUSIONSThe energy expenditure in reading should be higher than that of watching TV, however, the difference was not obvious. The expenditure rates might get closer to those of RMR. It might be regarded as an expenditure of very light physical active in Chinese.

The correlation between the expression of COX-2 and p53 protein in basal cell carcinoma (BCC) of eyelid and apoptosis was investigated. Specimens of BCC were collected from 40 cases (aged 28-68 y) at the Department of Pathology, Renmin Hospital of Wuhan University, and Department of Pathology, Zhongnan Hospital of Wuhan University during from 1999 to 2006. Five specimens of paracancerous tissues served as control group. Immunohistochemical staining was performed to detect the expression of COX-2 and p53 in the tissues. The average absorbance (A) and the average positive area rate of COX-2 and p53 protein were measured by image analysis. The positive area rate of COX-2 and p53 protein was analyzed by linear correlation analysis. It was found that COX-2 and p53 proteins were highly expressed in BCC of eyelid, and weakly expressed in paracancerous tissues. Image analysis revealed that the expression of COX-2 and p53 proteins in BCC of eyelid was significantly higher than that in paracancerous tissues (P<0.01). Spearman rank correlation analysis demonstrated a positive correlation between the expression of COX-2 and p53 (r=0.113, P=0.421). It was concluded that COX-2 can increase the expression of p53 protein, therefore suppressing apoptosis.

9.Expression of CD40 and Fas Ligand in Bowen's Disease, Squamous Cell Carcinoma and Basal Cell Carcinoma.
Yonsei Medical Journal 2002;43(3):304-308
Impaired regulation of apoptosis is known to be associated with the development of various cancers, and Fas/Fas-ligand (FasL) is known to play an important role in apoptosis. CD40 is a cell surface receptor, which when ligated modulates apoptosis in some cell types. The expressions of CD40 and FasL were examined in 10 normal skins, 7 Bowen's disease skins, 10 squamous cell carcinomas (SCCs) and 12 basal cell carcinomas (BCCs) immunohistochemically. In the normal epidermis, CD40 was more highly expressed in the keratinocytes of the squamous cell and granular layers than in those of the basal layer, and FasL expression was observed in the cell membrane of keratinocytes at the basal and squamous cell layers. CD40 expression was significantly higher in SCCs than in normal or Bowen's disease skin, while FasL expression was significantly higher in Bowen's disease than in SCCs. BCCs expressed the lowest levels of CD40 and FasL. These results suggest that altered CD40 and FasL expression may be related with the progression of SCC, and the marked reduced expression of CD40 and FasL may explain the biologic behavior of BCCs.

Neurodegeneration with brain iron accumulation (NBIA) is a disorder characterized by various mixtures of extrapyramidal, pyramidal or psychiatric abnormalities associated with iron accumulation in the basal ganglia. The mutations in the pantothenate kinase gene (PANK2) were found in approximately two thirds of the patients with NBIA. We report three patients wtih NBIA, and two of them showed mutations in the PANK2 gene.
