ABSTRACT
ABSTRACT Purpose: The regulatory effect of microRNA on diseases has been confirmed. This study aimed to evaluate the expression of microRNA-210-3p in age-related cataracts and assess the effect of abnormal miR-210-3p expressions on H2O2-induced SAR01/04 cells. Methods: Reverse-transcription quantitative polymerase chain reaction method was performed to assess the levels of miR-210-3p in aqueous humor samples. Receiver operating characteristic analysis was employed to assess the discrimination ability of miR-210-3p between patients with age-related cataracts and healthy people, and Pearson correlation analysis was used to identify the correlation between miR-210-3p and oxidative stress indices such as superoxide dismutase, glutathione peroxidase, malonaldehyde. Cell counting kit-8 assay and Transwell assay were used to estimate the biological function of H2O2-induced age-related cataract cell model. The levels of oxidative stress indices such as superoxide dismutase, glutathione peroxidase, and malonaldehyde were measured to evaluate the degree of oxidative stress damage in the age-related cataract cell model. The relationship between miR-210-3p and its target gene was verified by luciferase reporter gene analysis. Results: The miR-210-3p expression was elevated in the aqueous humor of patients with age-related cataracts. A high miR-210-3p expression showed a high diagnostic value for age-related cataracts and was significantly associated with the level of oxidative stress markers in patients with age-related cataracts. The inhibition of miR-210-3p can reverse oxidative stress stimulation and adverse effects on H2O2-induced cell function. Conclusions: The results suggested that miR-210-3p could promote cell viability, cell migration, and oxidative stress by targeting autophagy-related gene 7 in in vitro age-related cataract cell model.
RESUMO Objetivo: O efeito regulador do microRNA em doenças tem sido confirmado, e este artigo tentou avaliar a expressão do microRNA-210-3p na catarata relacionada à idade e avaliar o efeito da expressão anormal do miR-210-3p em células SAR01/04 induzidas por H2O2. Métodos: O método de transcrição reversa seguida de reação em cadeia da polimerase (RT-PCR) quantitativa foi realizado para avaliar os níveis de miR-210-3p em amostras de humor aquoso. Análise de características operacionais do receptor foi feita para avaliar a capacidade de discriminação do miR-210-3p entre pacientes com catarata relacionada à idade e pessoas saudáveis. A análise de correlação de Pearson identificou a correlação do miR-210-3p e índices de estresse oxidativo, como superóxido dismutase, glutationa peroxidase, malonaldeído. O ensaio de contagem de células kit-8 (cck-8) e o ensaio no sistema Transwell foram utilizados para estimar a função biológica do formato de células de catarata relacionada com a idade induzida por H2O2. Os níveis de índices de estresse oxidativo como superóxido dismutase, glutationa peroxidase e malonaldeído foram detectados para avaliar o grau de dano do estresse oxidativo em formato de células de catarata relacionada à idade. A relação entre miR-210-3p e seu gene alvo foi verificada por análise do gene repórter luciferase. Resultados: A expressão miR-210-3p foi elevada no humor aquoso de pacientes com catarata relacionada à idade. A expressão miR-210-3p altamente expressiva mostrou alto valor diagnóstico para catarata relacionada à idade e foi significativamente associado ao nível de marcadores de estresse oxidativo em pacientes com catarata relacionada à idade. A inibição de miR-210-3p pode reverter a estimulação do estresse oxidativo e os efeitos adversos da função celular induzida por H2O2. Conclusões: Esses dados sugeriram que a expressão miR-210-3p poderia promover a viabilidade celular, migração celular e estresse oxidativo ao direcionar genes ATG 7 relacionados à autofagia em modelo in vitro de células de catarata relacionadas à idade.
ABSTRACT
Las mujeres posponen su maternidad por el deseo de superación personal y profesional. Se conoce que la cantidad y calidad de los óvulos por ciclo dependen de la edad de la paciente. Las tasas de éxito en tratamientos de reproducción asistida disminuyen con la edad, especialmente después de los 40 años. Se observan tasas más altas de nacidos vivos en mujeres más jóvenes y las tasas disminuyen significativamente en mujeres mayores debido a la disminución de la fertilidad y el aumento de abortos espontáneos. Por ello, la edad es crucial al evaluar la posibilidad de un embarazo exitoso mediante tratamientos de reproducción asistida (TRA). Las indicaciones para realizar fertilización in vitro (FIV) con óvulos propios en mujeres mayores de 40 años incluyen iniciar lo más pronto procedimientos de alta complejidad, buena evaluación de la reserva ovárica con análisis de la hormona antimülleriana y conteo de folículos antrales para realizar asesoramiento genético, proponer FIV-inyección intracitoplasmática de espermatozoides (ICSI) antes de los 44 años, generar expectativas realistas y realizar consentimiento informado, con estadisticas propias. En la REDLARA, de todos los procedimientos de FIV-ICSI, el 34% de las pacientes tienen más de 40 años; se prefiere transferir blastocistos con prueba genética preimplantacional de aneuploidías (PGT-A) para seleccionar embriones euploides. Las tasas de éxito son bajas, inclusive cuando son tasas de embarazo por transferencia de un embrión en el grupo de mujeres ≥ 40 años (18,2% sin PGT, 42,7% con PGT en el IMRCRP). Se recomienda acumular óvulos o embriones realizando múltiples estimulaciones ováricas. Se debe optar por transferir un solo embrión para evitar complicaciones obstétricas con embarazos múltiples en pacientes ≥ 40 años, por el alto riesgo debido a la edad.
Women postpone motherhood because of their desire for personal and professional improvement. It is known that the quantity and quality of oocytes per cycle depends on the patient's age. Success rates in assisted reproduction treatments decrease with age, especially after 40 years of age. Higher live birth rates are observed in younger women, and rates decrease significantly in older women due to decreased fertility and increased miscarriages. Therefore, age is crucial when assessing the possibility of a successful pregnancy through assisted reproductive treatments (ART). The indications to perform in vitro fertilization (IVF) with own ovules in women older than 40 years include starting as soon as possible highly complex procedures, good evaluation of ovarian reserve with antimüllerian hormone analysis (AMH) and antral follicle count (AFC) for genetic counseling, proposing IVF-intracytoplasmatic sperm injection (ICSI) before the age of 44 years, generating realistic expectations and informed consent, with own statistics. At REDLARA, of all IVF-ICSI procedures, 34% of patients are over 40 years old; preference is given to transfer blastocysts with preimplantation genetic testing for aneuploidy (PGT-A) to select euploid embryos. Success rates are low, even when they are pregnancy rates per embryo transfer in the group of women ≥ 40 years (18.2% without PGT, 42.7% with PGT in IMRCRP). It is recommended to bank ovules or embryos by performing multiple ovarian stimulations. A single embryo transfer should be chosen to avoid obstetric complications with multiple pregnancies in patients ≤ 40 years, because of the high risk due to age.
ABSTRACT
ABSTRACT Objective The World Health Organization and Centers for Disease Control and Prevention recommend the use of face masks in public. This study aimed to evaluate the effects of face masks on pulse rate and partial blood oxygen saturation in patients without cardiorespiratory disorders. Methods A total of 150 volunteers of both sexes were divided into three groups (n=50) according to age (children, young adults, and older adults). The partial blood oxygen saturation and pulse rate were measured for each volunteer using a digital oximeter while wearing a facial mask and remaining at rest. The masks were removed for two minutes, and partial blood oxygen saturation and pulse rate were remeasured. The materials and types of masks used were recorded. The t -test for paired samples was used to compare the mean values obtained before and after removing the masks. Results The most frequently used mask was a two-layered cloth (64.7%). A decrease in pulse rate was observed after removing the face mask in males, particularly in children (p=0.006) and young adults (p=0.034). Partial blood oxygen saturation levels increased in young adult males after mask removal (p=0.01). Conclusion The two-layer cotton tissue face masks are associated with a higher pulse rate and reduced arterial blood oxygen saturation without associated clinical disorders, mainly in adult men with a lower tolerance to breathing and ear discomfort.
ABSTRACT
Objective:To analyze the interaction between obesity and diabetes, obesity and central obesity, central obesity and diabetes on hypertension.Methods:A questionnaire survey on 7 622 residents of Han Chinese ethnicity, aged 35-75 years, of Liangzhou district of Wuwei city were performed using multi-stage random sampling method in September to December 2018. Relative excess risk due to interaction, attributable proportion, synergy index, and 95% CI of the three were used to evaluate the additive interaction. Logistic regression analysis was used to analyze the multiplicative interaction. Results:Among the 7 622 residents, hypertension was detected in 3 212 residents, with a crude prevalence rate of 42.14% and a standardized incidence of 33.81%. There was a significant difference in incidence of hypertension between residents of different sexes, between residents at different ages, between obese residents and normal weight residents, between residents who had central obesity and those who had no central obesity, between residents who smoked and those who did not, between residents of different family economic situations, between residents who had different occupations, and between residents who had diabetes and those who had no diabetes (all P < 0.05). Getting primary, middle, and high school education was a protective factor against hypertension, while obesity, central obesity, diabetes, male gender, age greater than 45 years were the risk factors for hypertension. Multivariate logistic regression analysis showed that there was no additive interaction between obesity and diabetes, obesity and central obesity, central obesity and diabetes on hypertension. There was a multiplicative interaction between obesity and central obesity on hypertension ( P = 0.031, 95% CI: 0.53-0.97) and the interaction was antagonistic, but there were no multiplicative interaction between obesity and diabetes, central obesity and diabetes on hypertension. Conclusion:There was a negative multiplicative interaction between obesity and central obesity on hypertension.
ABSTRACT
Objective:To correlate serum 25-hydroxylvitamin D and parathyroid hormone levels with hypertension in patients with type 2 diabetes mellitus.Methods:A total of 100 patients with type 2 diabetes mellitus admitted to Siming Branch, the First Affiliated Hospital of Xiamen University, China from February 2018 to August 2020 were included in this study. These patients were stratified according to hypertension, and serum 25-hydroxyvitamin D level. The correlation between serum 25-hydroxyvitamin D and parathyroid hormone and hypertension was analyzed.Results:Among the 100 patients with type 2 diabetes meliitus, 25 patients had grade 1 hypertension, 30 patients had grade 2 hypertension, 45 patients had grade 3 hypertension, 5 patients (5%) had sufficient levels of 25-hydroxyvitamin D, 10 patients (10%) had insufficient levels of 25-hydroxyvitamin D, 85 patients (85%) had inadequate levels of 25-hydroxyvitamin D. Serum levels of 25-hydroxyvitamin D in patients with grade 1, grade 2, and grade 3 hypertension were (12.18 ± 2.52) μg/L, (12.45 ± 2.39) μg/L, (10.33 ± 1.26) μg/L, respectively, and parathyroid hormone levels were (36.48 ± 0.25) ng/L, (41.15 ± 0.39) ng/L, and (47.52 ± 1.44) ng/L, respectively. As blood pressure increased, the patient's serum levels of 25-hydroxyvitamin D increased first and then decreased, while parathyroid hormone levels gradually increased. However, there were no statistically significant differences in serum levels of 25-hydroxyvitamin D and parathyroid hormone between patients of different hypertension grades ( F = 0.96, 1.93, both P > 0.05). Logistic regression analysis showed that hypertension in type 2 diabetes patients was correlated with age, body mass index, serum 25 hydroxyvitamin D level, glycated hemoglobin and parathyroid hormone level ( OR = 1.076, 1.266, 0.937, 1.257, 1.000, all P < 0.05). Conclusion:The serum levels of 25-hydroxyvitamin D and parathyroid hormone in patients with type 2 diabetes mellitus are related to hypertension.
ABSTRACT
Objective:To investigate the sex differences in severe traumatic death patients of different ages.Methods:A total of 408 patients with severe trauma who received treatment in The Second Affiliated Hospital of Zhejiang University School of Medicine and Taizhou First People's Hospital from June 2017 to June 2022 were retrospectively analyzed. These patients were divided into the children group (≤ 14 years old, n = 47), the adult group (14-50 years old, n = 171), and the older adult group (> 50 years old, n = 90). Multivariate logistic regression was used to evaluate the difference in sex-based mortality among the groups. Nonlinear regression was used to evaluate the mutual interaction of increasing age and sex on the predicted survival rate. Results:Traffic accidents were the most common cause of death among men in the adult group (58.93%, χ2 = 7.95, P = 0.027). Falls were the most common cause of death among men in the older adult group (57.36%, χ2 = 8.63, P = 0.001). The Injury Severity Score of women in the adult and older adult groups was significantly higher in women than that of men in the same group [adult group: men: (24.39 ± 4.17) points, women: (26.32 ± 4.31) points, t = 2.84, P = 0.005). The incidence of post-traumatic complications in the older adult group was very higher in men than in women (respiratory failure: 28.68% in men, 14.75% in women, χ2 = 4.37, P = 0.036; circulatory failure: men: 27.13%, women: 13.11%, χ2 = 4.64, P=0.031; neuropsychiatric disorders: men: 20.93%, women: 8.20%, χ2 = 4.79, P = 0.029; respiratory infection: men: 31.78%, women: 18.03%, χ2 = 5.55, P = 0.047; other infectious diseases: men: 28.68%, women: 13.11%, χ2 = 0.69, P = 0.018). After adjusting for covariates, the mortality rate of men in the older adult group was significantly higher than that of women in the same group ( OR: 1.261, 95% CI: 1.185-1.343, P < 0.001). With the increase of age, the predicted survival rate after the trauma in patients of different sexes also decreased, in particular in men aged > 50 years (interaction P = 0.051). Among patients with blunt and severe head trauma, age-related mortality decline in patients aged > 50 years had a strong interaction with sex (interaction P = 0.002). In patients with penetrating trauma, there was a weak interaction between the predicted survival rate of different sexes (interaction P = 0.192). Conclusion:There is no significant difference in age-related change in post-traumatic mortality between different sexes. In the population aged > 50 years, men have a relatively higher risk of death than women.
ABSTRACT
Objective:To correlate neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and D-dimer (DD) with the severity of acute cholangitis.Methods:The clinical data of 96 patients with acute cholangitis who received treatment in Panjin Central Hospital from September 2019 to March 2021 were retrospectively analyzed. These patients were divided into three groups according to the severity of acute cholangitis: 36 patients with mild acute cholangitis (group A), 35 patients with moderate acute cholangitis (group B), and 25 patients with severe acute cholangitis (group C). The correlation between age, sex, NLR, PLR, DD, and the severity of acute cholangitis was compared among the three groups.Results:In groups A and B, the area under the receiver operating characteristic curve (AUC) showing the performance of DD, NLR, and PLR levels in predicting acute cholangitis was 0.800, 0.838, and 0.721, respectively, with the optimal cut-off value of 1.985 mg/L, 9.589, and 154.410, respectively. Among them, NLR had the largest AUC, and the highest sensitivity (82.9%), and had a high diagnostic value. In groups B and C, the AUC for DD, NLR, and PLR was 0.967, 0.915, and 0.543, respectively, with the optimal cut-off value of 6.000 mg/L, 22.390, and 264.220, respectively. DD and NLR had a diagnostic significance (both P < 0.05), but PLR had no diagnostic significance ( P > 0.05). The AUC for DD was the largest, and therefore DD had a great diagnostic significance. When NLR, PLR, and DD were jointly detected, the AUC was the highest and the diagnostic value was the highest. The AUC in groups A and B was 0.866, and that in groups B and C was 0.977. Conclusion:The levels of DD, NLR, and PLR increase in patients with acute cholangitis, which are related to the severity of the disease. DD, NLR, and PRL can be used as indicators to evaluate mild and moderate acute cholangitis, and NLR has the highest diagnostic value. DD and NLR can be used as indicators to evaluate moderate to severe acute cholangitis, and the effect of DD is superior to that of NLR. The combined detection of the three indicators can increase the value to evaluate the severity of acute cholangitis, and its effect is superior to that of a single detection. The combined detection of NLR, PLR, and DD is helpful for the clinical diagnosis and treatment of acute cholangitis.
ABSTRACT
Objective:To analyze the clinical characteristics of pulmonary tuberculosis (PTB) in patients with prediabetes mellitus (PreDM) and improve the understanding and diagnosis of pulmonary tuberculosis complicated by prediabetes mellitus (PreDM-PTB).Methods:The clinical data of 109 inpatients with PTB who underwent glycated hemoglobin A1c (HbA1c) examination admitted to Beijing Chest Hospital, Capital Medical University from January 2015 to January 2016 were retrospectively analyzed. These patients were divided into the PreDM-PTB group ( n = 45) and the non-PreDM-PTB group (N-PreDMPTB group, n = 64) according to HbA1c test results. Patient demographic data, clinical features, imaging data, bacteriological results, and other laboratory results were collected from all patients. Results:The mean age and body mass index (BMI) were higher in the PreDM-PTB group than the N-PreDMPTB group. The proportion of patients having a smoking history was higher in the PreDM-PTB group than the N-PreDMPTB group (46.7% vs. 25.0%). The proportions of patients who had a cough (88.9%), fever (55.6%), anorexia (17.8%), chest tightness (31.1%), shortness of breath (28.9%), weight loss (40.0%), and pleural effusion (22.2%) were higher in the PreDM-PTB group than the N-PreDMPTB group. Patients with PreDM-PTB were more prone to develop anemia (55.6%), hypoproteinemia (55.6%), and increased low-density lipoprotein (26.7%) compared with patients with N-PreDMPTB. The levels of D-Dimer (93.2%), C-reactive protein (86.7%), and erythrocyte sedimentation rate (79.1%) were increased in the PreDM-PTB group compared with the N-PreDMPTB group. Sputum smear results showed that the positivity of mycobacterium tuberculosis was higher in the PreDM-PTB group (74.4%) compared with the N-PreDMPTB group. There was no significant difference in drug resistance between the two groups ( P > 0.05). The positivity of blood tuberculosis antibody and blood T-cell spot test for tuberculosis infection were 60.9% and 84.6% respectively in the PreDM-PTB group and they were 50.9% and 95.2% respectively in the N-PreDMPTB group. There were no significant differences in these two indices between the two groups ( P = 0.321, 0.066). Conclusion:Patients with Pre-DMPTB have different clinical manifestations and auxiliary examination characteristics compared with patients with N-PreDMPTB patients, which should be paid more attention to by clinicians. Early intervention should be actively adopted to prevent diabetes development from pre-DM.
ABSTRACT
Objective:To explore the influence of interpregnancy interval (IPI) on pregnancy complications in multiparas.Methods:This was a retrospective cohort study involving 7 669 singleton parturients who delivered at ≥28 gestational weeks in the Affiliated Hospital of Southwest Medical University between December 2015 and December 2020 and had given birth in the third trimester before. Clinical data were collected, including the baseline characteristics, pregnancy complications, gestational weeks at delivery, and neonatal birth weight. According to the IPI, these women were divided into five groups: <12 months ( n=350), 12-<24 months ( n=945), 24-<60 months ( n=2 544), 60-<120 months ( n=2 478), and ≥120 months ( n=1 352). Based on the recommendation of the World Health Organization, pregnant women with an IPI of 24-<60 months were the control group. A multivariate logistic model was used to adjust for confounders and calculate the risks of pregnancy complications, including gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP). The influences of maternal age and previous delivery mode on the associations between IPI and maternal complications were analyzed. Analysis of variance (ANOVA), Chi-square test, and Cochran-Mantel-Haenszel Chi-square test were used for statistical analysis. Results:Compared with the control group, the incidence of GDM and HDP increased in the 60-<120 months group ( OR=1.23, 95% CI: 1.01-1.48 and OR=1.47, 95% CI: 1.13-1.92) and ≥120 months group ( OR=1.37, 95% CI:1.07-1.78 and OR=1.92, 95% CI: 1.39-2.64); the risks of uterine rupture/postpartum hemorrhage and placental abruption increased in the <12 months group ( OR=1.54, 95% CI: 1.01-2.34) and 12-<24 months group ( OR=2.38 95% CI: 1.13-5.02), respectively. In the 60-<120 months group, the risk of GDM increased only in non-elderly women (adjusted OR=1.71, 95% CI: 1.36-2.14), so did the risks of GDM and HDP in the ≥120 months group (adjusted OR=3.11, 95% CI: 2.10-4.62 and adjusted OR=1.81, 95% CI: 1.12-2.91). Among women who had undergone a previous cesarean section, the risk of GDM increased in the ≥120 months group (adjusted OR=1.35, 95% CI: 1.00-1.81). In the 60-<120 months group and ≥120 months group, the risk of HDP increased in postpartum women (adjusted OR=1.79, 95% CI: 1.08-2.95 and adjusted OR=3.32, 95% CI: 1.91-5.77). Conclusion:IPI≥60 months is a risk factor for GDM and HDP, and the associations between IPI and maternal complications are influenced by maternal age.
ABSTRACT
Objective:To investigate epidemiological characteristics of arsenic poisoning-related skin lesions in an arsenic tailing area in Hunan Province.Methods:A cross-sectional study was conducted. From October 2016 to January 2017, all residents aged over 18 years (except pregnant women) were enrolled from 3 villages in Baiyun Town, Shimen County, Hunan Province by using a cluster-sampling method. Demographic information was collected through a face-to-face questionnaire interview. All residents received skin examination performed by professional dermatologists, and blood, urine, and hair samples were collected for the measurement of arsenic levels. Non-conditional logistic regression analysis was performed to analyze factors associated with arsenic poisoning-related skin lesions.Results:A total of 1 092 eligible residents in the arsenic tailing area were recruited in this study, and 756 (69.2%, 95% CI: 66.5%, 72.0%) presented with arsenic poisoning-related skin lesions, including hyperkeratosis, hypo- or hyper-pigmentation. The median ( Q1, Q3) arsenic levels were 0.31 (0.14, 0.74) μg/g in hair samples ( n = 1 079), 0.84 (0.67, 1.10) μg/L in blood samples ( n =1 091), and 60.31 (41.71, 91.52) μg/L in urine samples ( n =1 092). Multivariable analysis showed that the occurrence of arsenic poisoning-related skin lesions was associated with age, residential location, and occupational arsenic exposure history, but was not associated with gender, ethnicity, education levels, migration history, arsenic levels in hair, blood, or urine. Compared with the group aged 18 - 39 years, the group aged 40 - 59 years and the group aged over 60 years showed significantly higher risks of arsenic poisoning-related skin lesions (adjusted OR = 11.34, 95% CI: 5.98, 21.50, P < 0.001; adjusted OR = 71.82, 95% CI: 35.81, 144.05, P < 0.001, respectively). Compared with the residents in the Wangyangqiao village, residents in the Heshan village and Huangchang village showed significantly higher risks of arsenic poisoning-related skin lesions (adjusted OR = 2.89, 95% CI: 2.05, 4.08, P < 0.001; adjusted OR = 4.13, 95% CI: 1.94, 8.78, P < 0.001, respectively). The risk of arsenic poisoning-related skin lesions was significantly higher in residents with occupational exposure history than in those without (adjusted OR = 1.99, 95% CI: 1.04, 3.83, P = 0.039) . Conclusion:Nearly 70% of the residents presented with arsenic poisoning-related skin lesions in an arsenic tailing area in Hunan Province, and the duration and previous degree of arsenic exposure were associated with the risk of arsenic poisoning-related skin lesions.
ABSTRACT
Objective:To evaluate the effect of age factors on the pharmacodynamics of intranasal dexmedetomidine for sedation in the pediatric patients undergoing transthoracic echocardiography(TTE).Methods:American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ pediatric patients, aged 1-24 months, undergoing TTE from August 2019 to May 2022, were selected. This trial was performed in two parts. Part Ⅰ Pediatric patients were divided into 4 age groups: 1-6 month group, 7-12 month group, 13-18 month group and 19-24 month group. The initial dose of dexmedetomidine was 2.0 μg/kg in 0.1 μg/kg increment/decrement. The dose of dexmedetomidine was determined by using modified Dixon′s up-and-down method. The ED 50 and 95% confidence interval of intranasally administered dexmedetomidine for sedation were calculated by the Dexon-Massey method. Part Ⅱ One hundred patients were divided into 4 age groups ( n= 25 each): 1-6 month group, 7-12 month group, 13-18 month group and 19-24 month group. The 4 groups were further divided into 5 subgroups ( n=5 each) according to the dose of dexmedetomidine: 2.1 μg/kg subgroup, 2.2 μg/kg subgroup, 2.3 μg/kg subgroup, 2.4 μg/kg subgroup, and 2.5 μg/kg subgroup. Part Ⅰ and part Ⅱ trials were combined, and the ED 95 and 95% confidence interval of intranasally administered dexmedetomidine for sedation were calculated using the probit method. Results:A total of 220 pediatric patients were enrolled. There was no significant difference in ED 50 and ED 95 of dexmedetomidine intranasally administered for sedation among groups ( P>0.05). Conclusions:The pharmacodynamics of intranasal dexmedetomidine for sedation shows no significant difference in age in the pediatric patients aged 1-24 months undergoing TTE.

Abstract Objective To evaluate swallowing-related quality of life in hospitalized elderly patients. Methods Cross-sectional analytical and observational approach was used in our study. Fifty-two elderly patients in a medical clinic of a public hospital in Distrito Federal [Federal District] participated. In addition to collecting sociodemographic and health condition data, the Eating Assessment Tool and the swallowing-related quality of life Questionnaire were applied. Results Of the elderly participants, 30.8% had a self-reported risk of dysphagia. The elderly at risk for dysphagia had lower scores in the "eating duration" domain and higher scores in the "mental health" domain. The only domain in which there was no statistical difference in the response pattern of the participants who were, or were not at risk for dysphagia was the "sleep domain." Among the variables of the 11 domains of the Swallowing Quality of Life Questionnaire, mostly positive correlations were found, with different degrees. Conclusion The swallowing-related quality of life of hospitalized elderly patients is directly manifested as decreased social interaction, increased eating time, fear to eat, and swallowing as a burden.
ABSTRACT
Purpose: To evaluate Vitamin B12 levels in healthcare professionals at a tertiary eyecare centre in India. Methods: This was a cross?sectional study conducted among healthcare professionals working at a tertiary eyecare centre in India. The sample included 2,374 employees. Chemiluminescent immunoassay method (reference range, 211–911 pg/ml) was used to assess serum vitamin B12 levels. Effect of age and gender was analyzed in vitamin B12 normal and vitamin B12 deficient groups. To evaluate risk factors, questions related to vitamin B12 deficiency were asked to the study participants in a survey. Results: The mean age of employees was 29.2 ± 0.7 years. Around 26% of them were vitamin B12 deficient. The proportion of males in the vitamin B12 deficient group (61.2%) was significantly higher (P < 0.0001) than that of the vitamin B12 normal group (44.9%). There was no effect of age on vitamin B12 levels in both vitamin B12 normal and vitamin B12 deficient groups. Mean vitamin B12 levels in males (289.1 ± 22.2 pg/ml) was significantly lower (P < 0.0001) than that of females (338.7 ± 30.0 pg/ml). Conclusion: This is the first such study on eyecare professionals. One?fourth of the eyecare professionals were vitamin B12 deficient. The proportion of males was higher in the vitamin B12 deficiency group. Males had lower vitamin B12 levels than females. Annual blood tests for vitamin B12 are recommended for timely diagnosis and management of vitamin B12 deficiency, particularly in males.
ABSTRACT
ABSTRACT Objective: To identify the factors associated with the use of the N95 respirator in Nursing and Medical students in the daily life of the covid-19 pandemic. Methods: Descriptive-analytical cross-sectional study carried out in 2020. A total of 830 students from three universities in Peru participated in the study. Associations were evaluated using Pearson's Chi-Square and multivariate Poisson modeling with log linkage. Results: Statistically significant differences were found between the preference to use the N95 respirator in relation to masks according to the activity they perform (p=0.001) and where they live (p=0.005). The multivariate analysis reported that the associated characteristics were age, activity performed, perception and fear of being infected by covid-19. Conclusion: The choice of N95 respirator is influenced by individual factors and perceptions. Spaces are needed to discuss daily life, the way of living, caring and educating, considering the socioeconomic dimensions and beliefs.

ABSTRACT
Objective@#To explore age, gender, and regional differences in physical activity among children and adolescents in China, and to provide a scientific reference for enhancing physical activity promotion.@*Methods@#A total of 4 269 children and adolescents aged 7 to 18 years were selected from six administrative regions of China (East China, Northwest China, North China, Central China, Southwest China and South China) using a stratified random cluster sampling method from September to December 2018. A questionnaire was administered to evaluate the physical activity level of Chinese children and adolescents aged 7 to 18.@*Results@#The overall detection rate of MVPA insufficiency in children and adolescents in China was 53.8%, of which the detection rate of MVPA insufficiency was 50.8% among boys and 57.1% among girls. Gender differences were statistically significant ( χ 2= 17.10 , P <0.05). Among the different age groups, the lowest detection rate of MVPA among 10-12 year olds was 43.6%, whereas the highest rate among 16-18 year olds was 63.0%, with significant differences between gender ( χ 2=4.33, 30.79, P <0.05). The P 50 values of total physical activity(TPA), light intensity physical activity(LPA), moderate intensity physical activity(MPA), vigorous intensity physical activity(VPA), moderate to vigorous physical activity(MVPA) were 92.9,24.3,41.4,7.1 and 55.7 min/d , respectively. The P 50 values of physical exercise, housework activities, entertainment activities and transportation activities were 34.3 , 2.1, 2.3 and 30.0 min/d, respectively, and the difference in age groups was statistically significant( H =95.03, 74.99, 300.26 , 64.16, P <0.05). There was a statistically significant difference in the detection rate of insufficient MVPA among children and adolescents in different regions ( χ 2=83.91, P <0.05). The lowest rate was 44.0% in North China, and the highest was 65.9% in East China.@*Conclusion@#The detection rate of MVPA insufficiency among Chinese children and adolescents firstly decreased and then increased with age. Boys participated in higher levels of physical activity than girls.
ABSTRACT
Objective:To explore the clinical characteristics and related risk factors of senile degenerative valvular heart disease(SDHVD), and to provide clinical basis for early prevention intervention of SDHVD.Methods:Clinical data of 1568 elderly patients ≥60 years old hospitalized in our hospital from January 2022 to June 2022 were collected to compare the clinical characteristics and analyze the risk factors of patients in the degenerative heart valve disease group and the non-degenerative heart valve disease group.Results:Age(per 10-year increase)( OR=2.107, 95% CI=1.518-2.924), blood calcium( OR=8.934, 95% CI=2.023-39.447), total cholesterol( OR=1.167, 95% CI=1.044-1.304), female( OR=2.098, 95% CI=1.305-3.374), and reduced mean platelet volume(MPV)( OR=0.818, 95% CI=0.682-0.981)were independent risk factors for the development of SDHVD( P<0.05).Post hoc two-by-two comparisons showed that different degrees of calcification were associated with age( P<0.05); apoA, UA, P, and FT3 were statistically significant in the no-calcification group compared with the control group( P<0.05); E/e′, PASP, and NT-ProBNP were statistically significant in the moderate calcification group compared with the control group( P<0.05); TC was statistically significant in the no-calcification and mild calcification groups compared with the control group There was statistical significance( P<0.05)compared with the control group. Conclusions:Age, blood calcium, total cholesterol, female, and reduced MPV are independent risk factors for SDHVD.
ABSTRACT
Objective@#To explore the correlation of age at menarche and prehypertension in female college students.@*Methods@#Age at menarche of 558 female college students was collected, while blood pressure, height and weight were measured, and body mass index(BMI) was calculated.@*Results@#Average age at menarche was (12.48±0.95) years, prevalence of prehypertension was 17.56% (98/558). The age of menarche was 8-11, 12, 13, 14, 15-19, and the prevalence of hypertension was 30.95%, 10.00% , 17.31%, 10.81%, 31.58% respectively, U shape association was observed in the association between prehypertension with age at menarche, lowest when age at menarche was <12 years. There was no significant difference in prehypertension between age at menarche was 13, 14 years old with 12-year-old group, those age at menarche 8-11 or 15-19 had a significantly higher risk of developing prehypertension than those 12-year-old( OR =4.03, 4.15, P <0.05).@*Conclusion@#Early or late menarche is associated with high blood pressure, appropriate intervention for girls with early menarche and obesity may be beneficial in reducing their future hypertension.
ABSTRACT
Objective:To analyze changes in nutritional status and immune function of elderly men receiving regular physical examinations, and to investigate the effects of aging on the nutritional status and immune function among elderly men.Methods:A total of 209 elderly men aged 60-101(72.9±11.5)years and receiving regular physical check-ups were enrolled.All research subjects were subjected to nutritional risk screening(NRS2002)and monitoring of nutrition and immune-related indicators, including routine blood work, blood biochemistry, immunoglobulin and T lymphocyte subsets.Results:Body weight, body mass index, hemoglobin, total protein, albumin and serum iron of elderly men decreased with age( F=21.754, 6.257, 47.528, 12.285, 18.397, 18.667, all P<0.001), with those aged 80 and above showing more significant decline and a greater proportion with malnutrition( χ2=77.134, P<0.001). The B lymphocyte counts of elderly men aged 80 and above were significantly lower( P<0.05)while serum IgA and IgG levels were significantly higher( F=3.110, 3.866, P=0.047, 0.022)than those of the 70-79 year old group.In addition, the B lymphocyte count and B lymphocyte ratio in malnourished elderly men were significantly lower( t=2.512, 2.874, P=0.013, 0.005), and IgA was significantly increased( t=2.513, P=0.017), compared with those with normal nutrition. Conclusions:The risk of malnutrition and reduced immune function among elderly men aged 80 years and above is significantly increased, and assessment and screening of the risk of malnutrition in the elderly should be stressed.
ABSTRACT
Objective:To evaluate the influence of sex on age-related changes in the glomerular filtration rate(GFR)in healthy individuals.Methods:A retrospective survey was performed.A total of 36 911 healthy subjects, of whom 43.61%(16 096 cases)were men, were enrolled and divided into six age groups: 18-29, 30-39, 40-49, 50-59, 60-69, and ≥70 years old.The estimated glomerular filtration rate(eGFR)was evaluated by the full age spectrum(FAS)equation.General linear regression analysis was used to calculate the annual decline rate of eGFR, and differences between the sexes in the same age group were evaluated using analysis of covariance.The chi-square test was used to compare the proportions of subjects with different eGFR levels between the sexes.Results:Regardless of sex, body mass index(BMI), systolic blood pressure(SBP)and fasting blood glucose(FBG)all increased gradually with age, while diastolic blood pressure(DBP)increased initially and then turned downward.The means of above results in men were generally higher than those in women of the same age.Before the age of 40, the levels of eGFR in men and women were relatively stable, with the mean eGFR in women higher than that in men[(121.98±16.77)ml·min -1·1.73 m -2vs.(111.01±13.36)ml·min -1·1.73 m -2, t=-53.793, P=0.000]; After the age of 40, eGFR decreased with age in both sexes, and the decline rate of eGFR in women was faster than that in men before the age of 70.Men had generally higher mean serum creatinine(Scr), blood urea nitrogen(BUN)and serum uric acid(UA)than women.With the increase of age, BUN levels increased gradually in men and women, but Scr levels started to increase after the age of 40 only in women and did not show a clear increase in men. Conclusions:There are sex-related differences with aging, as measured with many parameters.Young and middle-aged women have significantly higher eGFR than men of the same age, but eGFR declines faster with aging in women.
