Introduction: Cycling is a physical activity, which is practiced recreationally and as a work activity. Its effects may extend to the regulation of the expression of proinflammatory cytokines in obesity; however, details should be studied in the clinical indicators associated with other chronic-degenerative diseases. Objective: To identify changes in clinical parameters that serve as indicators of metabolic risk in people who perform cycling as a regular exercise and as a work activity. Methods: A cross-sectional and descriptive design research was carried out in the State of Mexico, Mexico. Three groups of 16 participants were formed from Toluca and surrounding municipalities. Body composition measurements and biochemical analyzes were performed to identify differences between groups through Student's t test and ANOVA analysis of variance. Results: Statistical analyzes reported significant differences in HDL and triglyceride concentrations. For the group of pedicab drivers it was more favorable, it is detailed how the time of the activity helps to maintain body composition parameters such as the percentage of muscle and adipose tissue. Conclusions: The benefits of cycling were presented with different degrees of efficiency according to the modality in which they are practiced. The variables do not change significantly in any group and may be dependent on other variables such as diet(AU)

Diabetes is a group of metabolic diseases in which there are high blood sugar levels over a prolonged period, and if untreated could lead to complications. This study, carried out at the Igbinedion university teaching hospital Okada to ascertain some hematological parameters, using 69 known diabetes patients who enrolled as an Out-patient in the General Out-Patient Department and 69 non-diabetes apparently healthy individuals as control. Thirty-nine of thesediabetic individuals were female, while thirty were male individuals. For the non-diabetic individuals, thirty-seven were female, and thirty-two were male representing 53.6% and 46.4% respectively. Ethical approval from the institution was sought prior to commencement of study and quality control of reagents was strictly maintained. Five millilitres of whole blood was collected into an Ethylene Diamine Tetra-Acetic acid (EDTA) anticoagulated bottle, and haematological parameters including PCV, HB, WBC, RBC,MCV, MCH, MCHC and platelet count were conducted for all individuals. Result obtained for Diabetic individuals showed a mean value of 34.63, 11.24, 4.41, 7.20 and 204.27 for PCV, Hb, RBC, WBC and platelets counts respectively, while for non-diabetic individuals, a mean value of 35.04, 10.09, 3.99, 7.07 and 262.56 respectively.Hb concentration and RBC count were statistically significant (p < 0.05). The Red cell indices, MCV and MCHC, were statistically significant. This study showed a statistically significant variation in some hematological parameters of diabetic patients compared to control group .Low platelet count and alteration to red cell morphology as indicated in values of MCV and MCHC among diabetic patients are indicators of thrombotic potential. Hence, routine screening of hematological parameters should be considered for proper management of diabetic patients.
ABSTRACT
Objective:To investigate the efficiency of biochemical screening and hotspot gene screening in the detection of neonatal inherited metabolic diseases.Methods:This was a prospective multi-center study.The study was carried out on 21 442 neonatal samples collected from 12 hospitals in 10 provinces from November 2020 to November 2021.The results of biochemical screening and hotspot gene screening were analyzed jointly.Biochemical screening methods included glucose-6-phosphate dehydrogenase deficiency enzyme activity assay and neonatal tandem mass spectrometry.Genetic screening analysis involved 135 genes associated with 75 neonatal diseases.Results:Of all the 21 442 neonates enrolled in the study, 21 205 were subject to biochemical screening.A total of 813 cases were positive in the initial screening, and 0.45% of them (95 cases) were diagnosed after recall.All the 21 442 neonates underwent gene screening.About 168 positive cases were detected in the initial screening, and 0.73% (156 cases) of them were confirmed finally.Biochemical and genetic screening improved the detection sensitivity of such diseases as primary carnitine deficiency, neonatal intrahepatic cholestasis caused by citrin deficiency, and 2-methylbutyrylglycinemia.Moreover, biochemical and genetic screening enabled the detection of more diseases, including the common single-gene genetic diseases such as thalassemia and Wilson disease.Conclusions:In neonatal screening, the combination of biochemical screening and gene screening expands the number of diseases detected and improve screening efficiency.
ABSTRACT
Objective@#To investigate the current situation of obesity and related metabolic abnormalities among preschool children, so as to provide theoretical support for future intervention.@*Methods@#A cohort of 3 952 children, born in Tianjin and enrolled in the kindergarten from September 2017 to October 2018, were selected to conduct a baseline survey and a three-year follow-up (questionnaire survey, physical examination and laboratory testing). At the same time, a two-way cohort study was conducted to retrospectively collect maternal prenatal examination, delivery and regular physical examination information of children from birth to preschool age from Tianjin Maternal and Child Health Information System.@*Results@#A total of 3 935, 3 654 and 2 739 children completed the follow up in the primary, middle and senior classes of kindergarten respectively. The height and weight of pre-school children increased with age, while the percentage of body fat decreased with age ( β-trend =-0.74, P <0.01). During three-year follow up, height, weight and body mass index of boys were higher than girls (P<0.05), while the percentage of body fat was lower than girls (primary class: 17.5%,18.5%; middle class: 16.4%,17.2%; senior class: 16.1%,17.1%, P <0.05). The detection rate of overweight (including obesity) and obesity increased with age( χ 2 trend were 15.51,38.72, P <0.05). The total detection rate of obesity increased from 5.4% at the baseline level to 9.6%. Laboratory test results showed that the detection rates of fasting blood glucose of boys were higher than that of girls in primary class, but blood lipid abnormalities were in the opposite (glucose: 7.7%, 4.8 %; lipid: 23.8% , 27.7%)( χ 2=12.01, 6.63, P <0.05).@*Conclusion@#The study has established a large growth cohort starting from the early embryonic stage, which will help to establish the strategies to promote children s health and prevent obesity and chronic diseases from multidimensional perspectives.
ABSTRACT
Objective To analyze the relationship between dietary and lifestyle inflammatory scores and metabolic syndrome, diabetes mellitus, cardiovascular disease, non-alcoholic fatty liver disease, tumor and other common metabolic diseases, and to explore the impact of dietary and lifestyle inflammatory potential on metabolic diseases, so as to provide new ideas for the diagnosis, treatment and prevention of metabolic diseases. Methods Databases such as CNKI, Wanfang , and PubMed were searched, and literatures related to the dietary and lifestyle inflammatory scores (DLIS) and metabolic diseases were reviewed . Results Seven articles showed that dietary and lifestyle inflammation scores had a positive correlation with metabolic diseases, and two articles showed that only lifestyle inflammatory scores had a positive correlation with metabolic diseases. Conclusion Dietary and lifestyle inflammatory scores may be positively correlated with metabolic diseases, but some results are still controversial. Further studies are needed to prove the correlation between DLIS and metabolic diseases.
ABSTRACT
Cardiovascular diseases (CVDs) and metabolic disorders are major components of noncommunicable diseases, causing an enormous health and economic burden worldwide. There are common risk factors and developmental mechanisms among them, indicating the far-reaching significance in exploring the corresponding therapeutic targets. MST1/2 kinases are well-established proapoptotic effectors that also bidirectionally regulate autophagic activity. Recent studies have demonstrated that MST1/2 influence the outcome of cardiovascular and metabolic diseases by regulating immune inflammation. In addition, drug development against them is in full swing. In this review, we mainly describe the roles and mechanisms of MST1/2 in apoptosis and autophagy in cardiovascular and metabolic events as well as emphasis on the existing evidence for their involvement in immune inflammation. Moreover, we summarize the latest progress of pharmacotherapy targeting MST1/2 and propose a new mode of drug combination therapy, which may be beneficial to seek more effective strategies to prevent and treat CVDs and metabolic disorders.
ABSTRACT
The cardioprotective effect of postmenopausal hormone replacement therapy (HRT) has been demonstrated in several studies. Similarly, physical exercise has yielded positive results. However, the effects of their combination remain inconclusive. This review describes the combined effects of physical exercise and hormone therapy on cardiovascular and metabolic health in postmenopausal women. We searched the Scopus, Web of Science, PubMed, and Embase databases and included randomized controlled trials published up to December 2021 on the combined effects of physical exercise and hormone therapy on cardiovascular and metabolic health in postmenopausal women. We identified 148 articles, of which only seven met the inclusion criteria (386 participants; 91 [23%] HRT + exercise; 104 [27%] HRT; 103 [27%] exercise; 88 [23%] placebo). The combined treatment further decreased systolic blood pressure (SBP) compared to the isolated effect of aerobic training (AT) (mean difference [MD]=-1.69; 95% confidence interval [CI]=-2.65 to -0.72, n=73). Nevertheless, it attenuated the decrease in diastolic blood pressure (DBP) (MD=0.78; 95%CI: 0.22-1.35, n=73), and the increase in peak oxygen consumption (VO2 peak) promoted by exercise (AT + HRT=2.8±1.4 vs AT + placebo=5.8±3.4, P=0.02). The combination of AT and oral HRT improved SBP. However, AT alone seemed to have a better effect on physical fitness and DBP in postmenopausal women.
ABSTRACT
ABSTRACT Non-insulinoma pancreatogenous hypoglycemia syndrome (NIPHS), without previous bariatric surgery, is a rare form of hypoglycemia in adult patients and is associated with nesidioblastosis. Adult-onset nesidioblastosis in diabetic patients is rare and histologically identical to "non-insulinoma pancreatogenous hypoglycemia syndrome (NIPHS)". Nesidioblastosis is rare in adults and clinically and biochemically mimics Insulinoma. In the literature, there have only been four cases of adult nesidioblastosis that followed diabetes mellitus. We report a case of nesidioblastosis in a 36-year-old diabetic female presenting with dizziness, sweating, and palpitations for three years. Selective non-invasive techniques failed to detect a tumor. Based on the pursuit of an insulinoma, a distal pancreatectomy specimen was received at our laboratory, and a diagnosis of nesidioblastosis was made. She is currently on follow-up with a favorable outcome. The definitive diagnosis of nesidioblastosis is made on a histological basis. The preferred form of treatment is pancreatic surgical resection. Nesidioblastosis should be taken into consideration in cases where diabetes transforms into hyperinsulinemic hypoglycemia.
ABSTRACT
Abstract The objective was to systematically search and synthesize the evidence available in the literature about the effect of physical exercise interventions Primary Health Care (PHC), carried out in Brazil, on cardiometabolic risk factors.

ABSTRACT
RESUMO A doença de Tay-Sachs é um distúrbio neurodegenerativo autossômico recessivo, o qual envolve o metabolismo dos lipídios, levando ao acúmulo de gangliosídeos nos tecidos, devido à deficiência da enzima hexosaminidase A. Esse depósito progressivo resulta em perda da função neurológica e, quando acomete as células ganglionares da mácula, causa o achado típico da doença, a "mácula em cereja". A patologia é diagnosticada por meio dos níveis de hexosaminidase A e hexosaminidase total no soro, além análise do DNA do gene HEXA. Este caso relata uma criança com doença de Tay-Sachs cujo diagnóstico foi suspeitado por conta dos achados oftalmológicos.
ABSTRACT Tay-Sachs Disease is an autosomal recessive neurodegenerative disorder, which involves the metabolism of lipids, leading to the accumulation of gangliosides in the tissues, due to the deficiency of the enzyme Hexosaminidase A. This progressive deposit results in loss of neurological function and, when it affects macula ganglion cells, it causes the typical disease finding, the "cherry red spot". The pathology is diagnosed through the levels of Hex A and total Hexosaminidase in the serum, in addition to the analysis of the DNA of the HEXA gene. This case reports a child with Tay-Sachs disease with a suspected diagnosis was through ophthalmologic findings.

@#Abstract: Objective To explore the accurate diagnosis of children with suspected rare inherited metabolic diseases, and to compare the application value of mass spectrometry and genetic testing in the diagnosis of rare inherited metabolic diseases (IMD). Methods The clinical information, mass spectrometry, and genetic results of children with suspected rare inherited metabolic diseases admitted to the Department of Pediatrics, the Affiliated Haikou Hospital of Xiangya Medical College, Central South University from March 2017 to December 2021 were analyzed retrospectively. Results 156 children with suspected rare inherited metabolic diseases were detected by mass spectrometry, 67 cases were positive and 89 cases were negative. Children with positive initial examination were retested, and 19 cases were positive. Among the retest positive cases, 13 cases were given genetic testing, and 9 cases were positive and 4 cases were negative. Among the initial negative cases, 54 children with poor therapeutic effect and high clinical suspicion of inherited metabolic diseases completed genetic testing, 15 cases were positive and 39 cases were negative. The results of the two detection methods were compared, the positive rate of mass spectrometry was 19.4%(13/67), and the positive rate of genetic testing was 35.8%(24/67). The continuity correction of Pearson's chi-square test of continuity correction suggested that the results of genetic testing and mass spectrometry were different, and the difference was statistically significant (P<0.05). Taking genetic testing as the gold standard, the sensitivity and specificity of mass spectrometry detection were 37.5% (95%CI:19.6%-59.2%) and 90.7% (95%CI:76.9%-97.0%), respectively. Among the 24 confirmed cases, 5 cases were diagnosed by gene panel and 19 cases were diagnosed by whole exome sequencing (WES). One case diagnosed by WES had no pathogenic mutation detected by gene panel before diagnosis. The detection of DNM1L gene c.1040C>G and AMN gene c.651+1G>C are novel pathogenic gene variants, which have clinical significance. Conclusions The ability of mass spectrometry in the diagnosis of inherited metabolic diseases is limited. Genetic testing, especially whole exome sequencing, can be the first choice for individualized diagnosis of suspected rare inherited metabolic diseases. In addition, the new mutation sites found by WES in this study enriched the pathogenic gene mutation spectrum and provided direction for further functional biological experiments.
ABSTRACT
Objective@#To explore the effect of all day physical activity in a 4 week closed training camp on the improvement of body composition and cardiovascular metabolic risk in metabolic unhealthy obese adolescents (MUO), so as to provide stronger evidence for the health promotion of obese adolescents with different metabolic states.@*Methods@#From July to August 2019, 58 obese adolescents aged 10-17 years from a closed training camp in Shenzhen were recruited and their body composition, blood pressure,lipid profile, and fasting blood glucose before admission were measured. They were divided into MUO group( n =31) and metabolic healthy obese (MHO) group( n =27). Using an Actigraphw GT3xBT triaxial accelerometer, the physical activity of the two groups during the whole day from 9:00 to 19:00 in a closed training camp for four weeks was recorded. After the conclusion of the camp, the above indicators were detected to compare the differences between the two groups before and after the intervention and the changes within the group.@*Results@#A total of 51.6% of MUO adolescents transitioned to MHO adolescents; Body weight, BMI Z score, body fat mass, SBP, TG, HDL-C, and FPG had time×group significant interactions( F=11.25, 11.25, 11.04, 4.89, 16.75, 5.92 , 5.57, P <0.05). The main effect of the group showed that before entering the camp, the BMI Z score, SBP, TG, and FPG in the MUO group were higher than those in the MHO group, while the HDL-C was lower than those in the MHO group( F=5.60, 6.62 , 20.21, 10.17, 31.04, P <0.05). The main effect of time showed that the body weight, BMI Z score, body fat mass, SBP, and TG of both groups decreased significantly( P <0.05), and HDL-C only showed a significant increase in the MUO group( P < 0.01 ). There was no significant change in FPG in both groups before and after intervention( P >0.05). The time×group interactions of body fat ratio, DBP, TC, and LDL-C was not significant( P >0.05), and the main effect of the group was not significant( P > 0.05 ), the main effect of time was significant( P <0.01).@*Conclusion@#Increased physical activity in the form of closed training camps can help MUO adolescents reduce fat, MUO adolescents should increase physical activity in their daily life to reduce the risk of cardiovascular metabolic diseases.

ABSTRACT
Exposure to fine particulate (PM2.5) has become a serious environmental risk factor threatening public health. A large number of epidemiological studies have shown that PM2.5 exposure is significantly associated with cardiovascular health. At present, studies have found that PM2.5 components are associated with the incidence and death of cardiovascular metabolic diseases (hypertension, diabetes, coronary heart disease, stroke, etc.), which may be due to the different components of PM2.5 in different regions, which have different effects on cardiovascular health. This article reviews the effects of different components of PM2.5 on cardiovascular metabolic diseases based on their sources and pathogenesis. The limitations of the effects of PM2.5 components on cardiovascular metabolic diseases are also discussed.
ABSTRACT
Cardiometabolic disease mainly refers to the cardiovascular disease caused by the increased metabolic burden, including hypertension, diabetes, dyslipidemia, coronary heart disease, stroke, and so on. In China, the incidence of this kind of disease is continuous rising, and cardiometabolic disease is more and more diagnosed in patients in younger age. Currently, continuous exploration of new biomarkers and detection methods, standardization of testing techniques, strengthening of clinical and laboratory communication and cooperation, and cultivation of interdisciplinary talents are the major focuses in term of promoting the development of laboratory medicine in the field of cardiovascular metabolism.
ABSTRACT
Objective:To investigate relationships between serum growth differentiation factor 15 (GDF15) and glycolipid metabolism in patients with metabolic associated fatty liver disease (MAFLD).Methods:The current investigation was a cross-sectional study. A total of 333 patients from the Fengxian District Central Hospital were recruited into the study after physical examination from February 2020 to February 2021. There were 107 patients with MAFLD and type 2 diabetes mellitus (T2DM), including 54 males and 53 females with a mean age of (57±11) years. There were 65 patients with simple MAFLD only, including 32 men and 33 women with a mean age of (49±5) years. There were 105 patients with T2DM only, including 53 men and 52 women, with a mean age of (56±10) years. A control group of 56 people without MAFLD or diabetes,28 male, 28 female, mean age (48±6) years, was also included in the study. Serum GDF15 was measured via enzyme-linked immunosorbent assays. IBM SPSS 26.0 was used for statistical analysis. Logistic regression was used to evaluate relationships between GDF15 and metabolic abnormalities in MAFLD patients.Results:GDF15 progressively increased in the control [385 (296, 484) ng/L], nonobese MAFLD [388 (319, 435) ng/L], obese MAFLD [426 (354, 527) ng/L], T2DM [664 (483, 900) ng/L], and MAFLD+T2DM groups [770 (560, 1 074) ng/L]( H=113.82, P=0.001). There was no significant difference in serum GDF15 between the simple MAFLD [406 (339, 524) ng/L] and control group ( U=1 505.50, P=0.132). GDF15 was significantly higher in the MAFLD+T2DM group than in the T2DM-only group ( U=4 573.50, P=0.019). In logistic regression analysis increased GDF15 was associated with increased risks of simple MAFLD [odds ratio ( OR)=2.202], T2DM ( OR=29.656), and MAFLD+T2DM( OR=58.197). In patients with MAFLD, serum GDF15 was higher in the FIB4 index>1.45 group [773 (534, 1 162) ng/L] than in the FIB4 index<1.45 group [527 (389, 787) ng/L] ( U=1 709.50, P<0.001). Increased GDF15 was associated with an increased risk of advanced liver fibrosis ( OR=2.388). Conclusion:In patients with simple MAFLD, GDF15 level was not significantly higher than in the control group. In the T2DM-only group and the MAFLD+T2DM group GDF15 was significantly higher than in the control group. Increased serum GDF15 was associated with increased risk and severity of MAFLD complicated with abnormal glucose and lipid metabolism. High GDF15 increased the risk of advanced fibrosis in MAFLD patients.

ABSTRACT
Resumo Fundamentos A determinação precisa do colesterol de lipoproteína de baixa densidade (LDL-C) é importante para se alcançar concentrações de LDL-C recomendadas por diretrizes e para reduzir resultados cardiovasculares adversos em pacientes diabéticos. A equação de Friedewald comumente usada (LDL-Cf) produz resultados imprecisos em pacientes diabéticos devido a dislipidemia diabética associada. Recentemente, duas novas equações - Martin/Hopkins (LDL-CMH) e Sampson (LDL-Cs) - foram desenvolvidas para melhorar a precisão da estimativa de LDL-C, mas os dados são insuficientes para sugerir a superioridade de uma equação sobre a outra. Objetivos O presente estudo comparou a precisão e a utilidade clínica das novas equações de Martin/Hopkins e Sampson em pacientes diabéticos. Método Foram incluídos no estudo quatrocentos e dois (402) pacientes com diabetes. O risco cardiovascular dos pacientes e as metas de LDL-C foram calculadas por diretrizes europeias. As concentrações de LDL-Cmh, LDL-Cs, e LDL-Cf calculadas foram comparadas à concentração de LDL-C direto (LDL-Cd) para testar a concordância entre essas equações e LDL-Cd. Um P valor <0,05 foi aceito como estatisticamente significativo. Resultados A LDL-CMH e a LDL-Cs tiveram concordância melhor com o LDL-Cd em comparação com a LDL-Cf, mas não houve diferenças estatísticas entre as novas equações para concordância com o LDL-Cd (Alfa de Cronbach de 0,955 para ambos, p=1). Da mesma forma, a LDL-CMH e a LDL-Cs tinham um grau semelhante de concordância com o LDL-Cd para determinar se o paciente estava dentro da meta de LDL-C (96,3% para LDL-Cmh e 96,0% para LDL-Cs), que eram ligeiramente melhores que a LDL-Cf (94,6%). Em pacientes com uma concentração de triglicérides >400 mg/dl, a concordância com o LDL-Cd foi ruim, independentemente do método usado. Conclusão As equações de Martin/Hopkins e Sampson mostram uma precisão similar para o cálculo de concentrações de LDL-C nos pacientes com diabetes, e ambas as equações são ligeiramente melhores que a equação de Friedewald.
Abstract Background The accurate determination of low-density lipoprotein cholesterol (LDL-C) is important to reach guideline-recommended LDL-C concentrations and to reduce adverse cardiovascular outcomes in diabetic patients. The commonly used Friedewald equation (LDL-Cf), gives inaccurate results in diabetic patients due to accompanying diabetic dyslipidemia. Recently two new equations - Martin/Hopkins (LDL-Cmh) and Sampson (LDL-Cs) - were developed to improve the accuracy of LDL-C estimation, but data are insufficient to suggest the superiority of one equation over the other one. Objective The present study compared the accuracy and clinical usefulness of novel Martin/Hopkins and Sampson equations in diabetic patients. Methods This study included 402 patients with diabetes. Patients' cardiovascular risk and LDL-C targets were calculated per European guidelines. Calculated LDL-Cmh, LDL-Cs, and LDL-Cf concentrations were compared with direct LDL-C concentration (LDL-Cd) to test agreement between these equations and LDL-Cd. A p-value <0.05 was accepted as statistically significant. Results Both LDL-Cmh and LDL-Cs had a better agreement with LDL-Cd as compared to LDL-Cf, but no statistical differences were found among novel equations for agreement with LDL-Cd (Cronbach's alpha 0.955 for both, p=1). Likewise, LDL-Cmh and LDL-Cs showed a similar degree of agreement with LDL-Cd in determining whether a patient was in a guideline-recommended LDL-C target (96.3% for LDL-Cmh and 96.0% for LDL-Cs), which were marginally better than LDL-Cf (94.6%). In patients with a triglyceride concentration >400 mg/dl, agreement with LDL-Cd was poor, regardless of the method used. Conclusion Martin/Hopkins and Sampson's equations show a similar accuracy for calculating LDL-C concentrations in patients with diabetes, and both equations were marginally better than the Friedewald equation.
