Epidemiology of Chronic Pulpitis, Dental Caries, and Periapical Disease and Their Possible Risk Factors in an Adult Chinese Population in the Northern Regions of China

Background: Dental diseases and disorders are reported to affect specific ages, genders, and races of patients. Therefore, epidemiological investigations are necessary for understanding dental diseases and disorders. Objectives: This cross-sectional study aims to determine the prevalence and potential risk factors of chronic pulpitis, dental caries, and periapical disease in adults seeking treatment at the Tianjin Stomatological Hospital, Tianjin, a major referral center in the Northern region of China. Methods: A total of 3,245 males and females visited the Department of Adult Dentistry and the Department of Endodontics of the Tianjin Stomatological Hospital, Tianjin, China, for oral health concerns from January 17, 2020, to November 18, 2023. Among these patients, 615 (19%) were receiving treatment for chronic pulpitis, dental caries, and/or periapical diseases at the institute. Demographic parameters and clinical examination results of 496 patients (119 patients were excluded due to missing information) who were being treated for chronic pulpitis (long-term inflammation of the dental pulp), dental caries (a biofilm-mediated, sugar-driven, multifactorial, dynamic disease), and/or periapical disease (inflammation around the tooth root) with varying severity (moderate or severe) were included in the study. Results: Of the 496 patients, 300 (60%) were females, 328 (66%) were aged 60 years or older, and 295 (59%) had issues with mandibular teeth. Among the patients, 250 (50%), 301 (61%), and 151 (30%) were diagnosed with dental caries, chronic pulpitis, and periapical disease(s), respectively. Female gender (P = 0.041), age ≥ 60 years (P = 0.045), and issues with mandibular teeth (P = 0.046) were found to be associated with chronic pulpitis, dental caries, and periapical diseases in the patients. Conclusions: The prevalence of dental diseases and disorders in Han Chinese adults is 19% in the Northern regions of China. Chronic pulpitis and dental caries are the most prevalent dental diseases, while periapical diseases occur less frequently among Han Chinese adults in the Northern regions of China. Females, individuals aged ≥ 60 years, and issues with mandibular teeth are independent risk factors for the development of chronic pulpitis, dental caries, and periapical disease in adult patients in Northern regions of China. Policymakers in China should consider the findings of this study to reduce dental diseases and disorders in Chinese adults, especially in the Northern regions of China.

Identify unmet needs in diabetes care in Shandong, China: a secondary analysis of a cross-sectional study using cascade of care framework

BackgroundThe continuum management of diabetes remains under-evaluated in China. This study aimed to estimate the proportions of diabetes adults at each stage of the cascade of care framework in Shandong, China.MethodsWe conducted a secondary analysis using the 2018 China Adult Chronic Disease and Nutrition Surveillance (CACDNS) data in Shandong. This nationwide cross-sectional survey was conducted between September and November 2018, investigating the major chronic diseases among Chinese adults through interviews, physical examinations, and laboratory tests. We employed the cascade model to examine the proportion of diabetes adults, including both type 1 and type 2, from diabetes screening, diagnosis, pharmaceutical and non-pharmaceutical treatments, to single and comprehensive management targets, and quantified the attrition between each stage. Diabetes screening was defined as participants reported to have ever received a blood glucose test. Diabetes diagnosis was defined as: 1) fasting plasma glucose (FPG) ≥ 126 mg/dL, or 2) 2-h oral glucose tolerance test (2 h-OGTT) ≥ 200 mg/dL, or 3) hemoglobin A1c (HbA1c) ≥ 6.5%, or 4) self-reported diabetes. Diabetes management targets included: 1) single glycemic target of personalized HbA1c level, 2) comprehensive ABC targets of personalized HbA1c level, blood pressure (BP) < 140/80 mm Hg, and low-density lipoprotein cholesterol (LDL-c) level < 2.6 mmol/L, 3) lifestyle target of not currently smoking. The estimated proportion was calculated through self-reported diabetes status and FPG, 2h-OGTT and HbA1c. The number of diabetes cases in Shandong was extrapolated using the 2018 provincial census data for adults aged 18 years and above (N = 80.6 million). The cascade of diabetes care was further examined by age, sex, and Basic Public Health Service (BPHS) enrollment.ResultsThis secondary analysis included 8,462 individuals (47.8% males, median age: 49.0), among whom 12.4% had diabetes (self-reported: 4.2%, newly diagnosed: 8.2%) and 41.1% had prediabetes. In 2018, an estimated 9.2 million adults in Shandong had diabetes, with 6.4 million (69.6%) receiving diabetes screening but 6.2 million (67.7%) remaining unaware of their conditions. Among self-reported diabetes adults, 2.7 million (86.4%) and 2.8 million (89.6%) received pharmaceutical and non-pharmaceutical treatment, respectively. Of those with treatments, 1.2 million (58.2%) met personalized glycemic target. A rapid decline, however, was observed in BP (31.1%) and LDL-c (39.3%) control among diabetes patients with multimorbidity (≥ 2 diseases). Ultimately, 0.1 million self-reported diabetes adults (3.8%) achieved the ABC targets. BPHS Enrollment slightly improved comprehensive management with ABC targets.ConclusionsA significant unmet need exists for diabetes adults from screening to management, particularly the comprehensive management of glycemia, BP and LDL-c levels among those with multimorbidity. Tailored strategies and appropriate allocation of healthcare resource is needed to addressing gaps in care continuum and reduce long-term disease burden.

Focus on cardiovascular metabolism research and guide the prevention and control of chronic diseases in the older adults

With the acceleration of global population aging, the incidence and mortality of cardiovascular disease (CVD) among the older adults are continuously rising, posing an essential public health challenge that severely threatens their health and quality of life. In recent years, significant progress has been made in the research on epidemiological characteristics, risk factors, and prevention strategies of CVD in older adults. This review aims to summarize the current research status of CVD in the old adults, explore key factors affecting cardiovascular health, including genetic factors, lifestyle, and metabolic abnormalities, and evaluate the effectiveness of novel interventions. The goal is to provide a scientific basis for developing CVD prevention and management strategies tailored to the old adults.

Aspartate/alanine aminotransferase ratio and development of chronic kidney disease in non-diabetic men and women: a population-based longitudinal study in Kagawa, Japan.

The relationship between serum aspartate/alanine aminotransferase ratio (AST/ALT) and subsequent development of chronic kidney disease (CKD) in non-diabetic Asian adults has not yet been fully investigated in longitudinal studies. The study included all middle-aged and older non-diabetic Japanese citizens who received health check-ups in Zentsuji, Kagawa, Japan (1998-2023). AST/ALT was classified into three categories: < 1.0 (reference), 1.0- < 1.5, and ≥ 1.5. CKD was defined as an estimated glomerular filtration rate of < 60mL/min/1.73 m2. The Weibull accelerated failure time model was used to examine the association between AST/ALT categories and subsequent CKD onset because the proportional hazards assumption was violated. Of 6309 men and 9192 women, 2966 men and 4395 women remained in the final cohort. After a mean follow-up of 7.50years for men and 8.34years for women, 33.7% of men and 34.0% of women developed CKD. Women had higher AST/ALT than men. In women, a dose-response relationship was observed, with a 9% shorter survival time to CKD onset for AST/ALT ≥ 1.5 compared with AST/ALT < 1.0. In contrast, men had a shorter survival time to CKD onset by point estimates, but the 95% confidence intervals crossed 1 in all models. In this study comparing the risks of CKD development in non-diabetic men and women by AST/ALT levels, a dose-response relationship was only observed in women. Differences in the distribution of AST/ALT by sex may have affected the results. Therefore, in non-diabetic Japanese women, AST/ALT may be used as an indicator of future CKD development.

Prevalence of bacteriuria and bacterial resistance in adolescents from the center of the state of Tlaxcala, Mexico.

Urinary tract infections and bacteriuria are common in the pediatric population, and antibiotic resistance is increasing significantly. Recurrent urinary infections, symptomatic or asymptomatic, are a risk factor for developing chronic kidney disease in adolescents and young adults. This study aimed to assess the prevalence of bacteriuria diagnosed by culture to identify the main causal agents and sensitivity to antibiotics in adolescents from the central region of the state of Tlaxcala. A cross-sectional study was carried out among 905 adolescents from 11 to 18 years old who lived in the central region of the state of Tlaxcala, Mexico. Bacteriuria was evaluated by positive nitrites and leukocyte esterase, and urine culture with antibiogram. Multivariate logistic regression models were executed to evaluate the risk of presenting bacteriuria, with a confidence level of 95%. A total of 31 participants had a positive urine culture, with a bacteriuria prevalence of 3.4%, of which 29 cases were asymptomatic. The most frequent agent was Escherichia coli) in both sexes (28.6% in men and 29.7% in women) and regarding bacterial resistance: E. coli presented greater resistance to ampicillin, trimethoprim/sulfametoxazol and ceftriaxone. The risk factors associated with bacteriuria were female sex, sexual activity, use of contraceptives, and greater consumption of sweetened beverages. Bacteriuria is common in this adolescent population, so its early identification is necessary to treat it, and to prevent its complications.

Use of Disinfectants and Cleaning Products Associated with Respiratory Disease: A Scoping Review

Introduction: there is extensive evidence on the harmful respiratory effects of exposure to disinfectants and cleaning products. Methodology: an exploratory systematic review was carried out in five databases: LILACS, PubMed, MEDLINE and BIREME. Twenty articles from 2013 to 2024 were selected for the present review. Results: chemical compounds present in some disinfectants and cleaning products such as Polyhexamethylene guanidine (PHMG) and Chloromethylisothiazolinone/Methylisothiazolinone (CMIT/MIT) influence the development of Humidifier Respiratory Distress Syndrome (HDRS) and increased incidence of asthma and Chronic Obstructive Pulmonary Disease (COPD) in adults. Conclusions: There is a relationship between exposure to chemical compounds in certain disinfectants and lung health impairment. It is imperative to increase the general population’s awareness of the effects of these substances will lead to improved self-care in those who are in daily contact with these elements.

Research progress on epigenetic mechanism of reproductive disorders

The "Developmental Origins of Health and Disease, DOHaD" theory suggests that adverse factors in early life can lead to the occurrence of chronic diseases in adulthood. In recent years, it has been discovered that maternal factors, intrauterine development environment and environmental exposure during pregnancy can mediate the changes of early egg/embryo development, promote the occurrence of reproductive disorders such as polycystic ovary syndrome, diminished ovarian reserve, and endometriosis, and induce intergenerational genetic effects. This article has reviewed the progress of research on maternal factors which may affect the pathogenesis of reproductive disorders, and expounds its mechanism from the perspectives of epigenetic mechanisms such as DNA methylation, histone modification and non-coding small RNA (miRNA) modification, with an aim to provide insights for studying the occurrence of adult reproductive disorders in early life and before pregnancy.

Adverse childhood experiences and diet quality in the national sample of Poles: The mediating role of emotion regulation

Adverse childhood experiences (ACEs) increase the risk of adverse psychological and physical outcomes and chronic disease in adulthood. The mechanism of this relationship is still unclear. ACEs might exert their negative influence on adult health via both dietary and psychological axes. Our study aimed to examine the relationship between ACEs and diet quality in the national sample of Poles. We also aimed to determine whether difficulty in regulating emotions act as a mediator of this relationship. The national Polish sample of adults (n = 3557) took part in this study. ACEs were assessed via the Adverse Childhood Experiences Questionnaire. Data on food consumption frequency over the past year, body weight and height were collected using the self-administered version of the Dietary Habits and Nutrition Beliefs Questionnaire (KomPAN®). Two diet quality scores were evaluated: Pro-Healthy-Diet-Index-10 (pHDI) and Non-Healthy-Diet-Index-14 (nHDI). Emotion regulation (ER) was evaluated via the Difficulties in Emotion Regulation Scale (DERS). Path analysis was used to examine the associations between the variables, firstly formulated by theoretical assumptions expressed by directed acyclic graphs (DAGs). A higher number of ACEs was related to higher difficulties in ER in adults (p < 0.001), which in turn was related to lower pHDI (p < 0.001) and higher nHDI (p = 0.027). Our findings strengthen the rationale for ACEs screening as a potential risk factor for diet-related chronic disease in adulthood. They provide a framework for public health prevention strategies via interventions targeting diet quality and emotional regulation in the setting of multidisciplinary practice.

Health literacy of pregnant women in Hungary

Abstract Health literacy determines our state of health and through this our quality of life. The health behavior of women of reproductive age should be treated with priority, since the lifestyle of pregnant women shows a correlation with the occurrence of premature birth and intrauterine development, and also between fetal development and the occurrence of chronic diseases in adulthood. The aim of our research is to explore the factors influencing the health behavior of pregnant women, to analyze regional differences, and to identify the causes of regional differences and inequalities. During a prospective, cross-sectional study, the health behavior of pregnant women living in Hungary was assessed using a questionnaire. In the course of our research, we examined health literacy using two measuring instruments, the Chew questionnaire and The Newest Vital Sign test. A total of 2,000 questionnaires were distributed of which 1,655 evaluable questionnaires were returned, the willingness to answer was 75%. The most people considered their own health to be good or very good (59.7%). 59.5% of the respondents changed their health behavior because of their pregnancy, mainly for the sake of the health of the fetus. 18.1% of pregnant women most likely have insufficient, 15.0% probably limited and 48.1% most likely have adequate functional health literacy. Age, education, place of residence and financial situation of pregnant women show a significant correlation with health literacy. Our results confirmed that sociodemographic factors, especially age and education, significantly influence the health literacy, perceived health status and health behavior of pregnant women. The two health literacy questionnaires we use can be combined well with each other and complement each other. The results greatly contribute to the development of health literacy, and thus to the development of individual and community-level strategies for improving health behavior in the field of pregnant women’s care. Key messages • Health literacy of pregnant women in Hungary. • Health literacy in health promotion.

Increasing trends in hypertension-related mortality in European Union 27 countries from 2011 to 2019

Abstract Background Arterial Hypertension (HT) is one of the most common chronic cardiovascular disease in adults and a leading cause of disability and mortality worldwide. However, update data regarding the HT-related mortality trends in Europe are lacking. Therefore, we assess the age- and sex- specific trends in HT-related mortality in the 27 European Union Member States (EU-27) between years 2011 and 2029. Methods Data were retrieved from the free publicly available EUROSTAT death certificate database to examine age-adjusted HT-related mortality rates (AAMR) (per 100.000 people) and relative average annual percentage change (AAPC) across all European Union 27 countries (EU27) from 2011 to 2019 using the International Classification of diseases, Tenth Revision (ICD-10) codes I10-I13 and I15. To calculate annual trends in HT-related mortality, we assessed the average annual percent change (AAPC) and relative 95% confidence intervals (CIs) using Joinpoint regression analysis. Results Over the study period, 254.540 HT-related deaths (157,081 males) were listed in EU27. Age-adjusted HT-related death increased from 9.12 to 10.7 per 100,000 people [AAPC: +1.5% (95% CI: 0.8-2.0), p&amp;lt;0.001]. Specifically, the HT-related mortality increased in males [AAPC: +1.8 (95% CI: 0.9-2.6) while decreased in women [AAPC: -1.1 (95% CI: -2.0 to 0.2), p=0.001]. Additionally, the HT-related mortality rates increased in northern [+1.5 (95% CI: 0.7 to 2.3), p&amp;lt;0.001] and eastern [AAPC: +3.9 (95% CI: 2.3 to 5.4), p&amp;lt;0.001] EU-27 states. Conversely, the AAMR plateaued in southern [AAPC: -0.1 (95% ci: 0.6 to 0.7), p=0.96)] and western EU-27 countries [AAPC: 1.0 (95% CI: -0.1 to 2.1, p=0.07] over the same period. Conclusions In EU27, HT-related mortality increased from 2011 to 2019, especially in men. However, significant disparities in HT-related mortality rates still exist between different European regions.

Dose-Response Relationship Between Serum 25(OH)D and the Risk of Abnormal Glycemic Status in Chinese Older Adults.

The relationship between serum 25-hydroxyvitaminD (25(OH)D) concentration and the risk of abnormal glycemic status remains contradictory. Whether sufficient 25(OH)D plays a role in reducing the risk of diabetes and prediabetes is debatable. Its dose-response relationship and the optimal 25(OH)D threshold are not clear. This study investigated the relationship between serum 25(OH)D and the risk of abnormal glycemic status to explore the optimal cut-off value. This study included 5856 Chinese older adults aged 60 years and above from the China Adult Chronic Disease and Nutrition Survey (CACDNS 2015-2017). Serum 25(OH)D concentration was measured via an enzyme-linked immuosorbent assay. Abnormal glycemic status in the present study includes diabetes and prediabetes. Statistical methods such as a locally weighted regression and smoothing scatterplot (LOESS), restricted cubic spline regression (RCS) and binary and trend logistic regression were used to explore the dose-response relationship and the optimal 25(OH)D threshold. The concentration of 25(OH)D was nonlinearly related to the levels of FPG and HbA1C in the LOESS curves. The nonlinear relation between 25(OH)D and the risk of diabetes and prediabetes was illustrated in the RCS curves and the optimal 25(OH)D threshold beneficial for diabetes was preliminarily explored to be 29.06 ng/mL, but no threshold for prediabetes was found. The dose-response results showed that for each 1 ng/mL increase in 25(OH)D, the risk of the fasting glucose type of diabetes reduced by 2.1%, the risk of the abnormal HbA1C type of diabetes reduced by 2.2% and the risk of the mixed type of diabetes reduced by 1.7%, whereas a dose-response relationship was not found for prediabetes. Higher serum 25(OH)D concentrations in Chinese older adults were associated with a reduced risk of glycemic abnormalities. The optimal 25(OH)D cut-off value was sufficiently beneficial if the diseased diabetes risk was 29.06 ng/mL, but no threshold was found for prediabetes.

Perceptions of the 2D short animated videos for literacy against chronic diseases among adults with diabetes and/or hypertension: a qualitative study in primary care clinics.

Animation has promise for teaching complex health content through smartphone applications. However, smartphones have had limited use in Thailand for health literacy improvement among adults with chronic diseases. This study aims to explore the perceptions of adults with diabetes and/or hypertension resulting from 2D short animated videos for literacy against chronic disease that are available via smartphones. Four animated videos were initially developed based on clinical practice guidelines and nursing experience. Physicians, an expert in health education, and an animation team developed and revised scripts and storyboards of the animated videos. Lastly, videos were validated by physicians and health educators for content breadth and depth and by media experts for motion graphics and illustration. Each video presents a different situation in diabetes, hypertension, missing appointments, and obesity, ranging from 2.18 to 4.14min in duration. The inclusion criteria were adults 35-70 years old with diabetes or hypertension who received care from primary care units. Thematic analysis was performed on the extracted data. Twenty participants with a mean age of 58.4 years (SD 6.7; ranged 41-68) were focus-group interviewed. Three animation elements were assessed, including presentation, impacts, and suggestions. Participants had positive responses regarding the presentation (suitability of images and smooth motion graphics, short length of videos, simple language, understandable content, and clear sound) and impacts (recalling information, enhancing engagement, and motivating health awareness and behavior change). Suggested improvements were for a bigger font size for subtitles and considering the use of spoken text instead of on-screen text for recommendations at the end of the animations. Animated videos are acceptable for delivering health information. Pilot testing animated videos for promoting literacy against chronic diseases in adults with diabetes and hypertension is needed for optimal utility.

Association of depressive symptoms and incident chronic kidney disease in middle-aged and older adults

BackgroundEmerging evidence suggests that depressive symptoms may be a risk factor for the development of Chronic kidney disease (CKD). This study aimed to investigate the association between depressive symptoms and the incidence of CKD in middle-aged and older Chinese adults. MethodsWe utilized data from the 2011–2020 China Health and Retirement Longitudinal Study (CHARLS). Depressive symptoms were assessed using the 10-item Center for Epidemiologic Studies Depression Scale (CES-D). Incident CKD was defined based on the estimated glomerular filtration rate ≤ 60 mL/min/m2 or self-reported. Cox proportional hazard models were used to estimate the hazard ratio (HR) and 95 % confidence intervals (95 % CI) for incident CKD, adjusting for potential confounders. ResultsAmong the 10,996 participants without baseline CKD, 890 developed CKD during a median follow-up of 9.0 years. After adjusting for potential covariates, participants with depressive symptoms had a significantly higher risk of developing CKD compared to those without depressive symptoms (HR: 1.450; 95 % CI: 1.249–1.682). The association remained statistically significant when the CES-D was scored according to the severity of depressive symptoms, i.e., quintiles. A linear positive association between total CES-D score and risk of incident CKD was also found using restricted cubic spline regression (Pfor non-linearity = 0.114). ConclusionsDepressive symptoms are significantly associated with an increased risk of incident CKD in middle-aged and older Chinese adults. These findings underscore the importance of mental health screening and interventions in preventing CKD in this population.

Association between dietary fiber intake and chronic kidney disease in adults with and without hypertension in the United States: a cross-sectional study of NHANES 2009–2020

While previous research has highlighted the potential advantages of increasing dietary fiber intake (DFI) for managing hypertension and chronic kidney disease (CKD), there is a gap in large-scale empirical studies examining the relationship between DFI and CKD among hypertensive and nonhypertensive cohorts independently. This study involved 22,871 participants sourced from the NHANES database spanning 2009 to 2020, who were divided into hypertensive (n = 9,861) and nonhypertensive (n = 13,010) groups. The analysis revealed a significant inverse correlation between DFI and CKD prevalence across the sample after adjusting for various covariates (OR = 0.98, 95% CI: 0.97–0.99, p = 0.001). Within the subset of hypertensive individuals, this inverse association mirrors the findings of the overall sample, indicating that a higher DFI was associated with a reduced occurrence of CKD (OR = 0.97, 95% CI: 0.96–0.99, p < 0.001). However, this correlation was not detected in the nonhypertensive group (OR = 0.99, 95% CI: 0.98–1.01, p = 0.285). The RCS analysis further confirmed a pronounced nonlinear inverse relationship between DFI and CKD prevalence in both the entire cohort and the hypertensive group but not in the nonhypertensive group. Further scrutiny of the hypertensive group revealed that individuals with a higher DFI had 33% lower odds of CKD progression for the moderate risk level and 36% lower odds for the high to very high risk level. Subgroup analyses confirmed the consistency of these relationships across various demographics. In summary, this investigation revealed a significant inverse relationship between DFI and CKD prevalence in US adults with hypertension, a relationship not observed in nonhypertensive individuals.

Impact of renal impairment on the pharmacokinetic profile of intravenous difelikefalin, a kappa opioid receptor agonist for the treatment of pruritus

BackgroundDifelikefalin is a selective kappa opioid receptor agonist that is approved for the treatment of moderate-to-severe pruritus associated with chronic kidney disease in adults undergoing hemodialysis (HD). In this study, we assessed the pharmacokinetics (PK) of intravenous (IV) difelikefalin in healthy subjects, in non–dialysis-dependent (NDD) subjects with varying stages of kidney disease, and in subjects with end-stage renal disease (ESRD) undergoing HD.MethodsThe PK and safety of single IV doses of difelikefalin (3.0 mcg/kg) were initially evaluated in NDD subjects with mild, moderate, or severe renal impairment compared with matched healthy subjects. Based on those data, the PK and safety of 3 dose levels of IV difelikefalin (0.5, 1.0, or 2.5 mcg/kg) were compared with matched placebo in subjects undergoing HD with each dose administered following dialysis, 3 times over a 1-week treatment period).ResultsSingle IV dosing of difelikefalin in NDD subjects (N = 36) with mild renal impairment demonstrated comparable exposure to healthy subjects with normal renal function, while subjects with moderate or severe renal impairment had higher total exposure. NDD subjects with severe renal impairment had higher total exposure compared with those with moderate renal impairment (i.e., exposure in severe NDD > moderate NDD > mild NDD ≈ healthy subjects). Clearance of difelikefalin correspondingly decreased with increasing renal impairment. In the multiple-dose study in subjects with ESRD undergoing HD (N = 19), IV difelikefalin demonstrated dose proportionality and was shown to be mostly cleared by dialysis; steady state was achieved with the second dose on day 3. Safety findings for all subjects were consistent with the known profile of IV difelikefalin.ConclusionsIV difelikefalin was well tolerated. Similar exposure was observed in NDD subjects with mild renal impairment compared with healthy subjects with normal renal function, with reduced clearance and higher exposure in NDD subjects with moderate or severe renal impairment. Dose proportionality was demonstrated in subjects with ESRD undergoing HD administered IV difelikefalin 3 times per week following dialysis and was shown to be mostly cleared by dialysis.Trial registrationSingle-dose study: NA; multiple-dose study: ClinicalTrials.gov registration number NCT02229929, first registration 03/09/2014.

Association Between Triglyceride Glucose Index and Chronic Kidney Disease in Normal-Weight Chinese Adults With Hypertension.

This study aimed to examine the association between the triglyceride-glucose (TyG) index and chronic kidney disease (CKD) in normotensive adults with hypertension and further investigate potential effect modifiers of this association. A total of 7975 normoweight hypertensive participants were enrolled from the Chinese H-type hypertension registry (CHHRS) cohort. The TyG index was calculated using the formula: ln (fasting triglyceride [mg/dL] × fasting plasma glucose [mg/dL])/2. CKD was defined as an estimated glomerular filtration rate (eGFR) < 60mL/min/1.73 m2 of body surface area. Multivariate logistic regression analysis revealed a 50% increased risk of CKD (OR: 1.50, 95% CI: 1.26-1.79) for each unit increase in the TyG index. A linear dose-response relationship between the TyG index and CKD risk was observed using restricted cubic spline analysis. Compared to the first quartile of the TyG index, the fourth quartile showed a significantly higher risk of CKD (OR: 1.88; 95% CI: 1.41-2.50). Subgroup analysis identified a stronger association between the TyG index and CKD risk in males and individuals with a history of alcohol consumption (all p values for interaction < 0.05). In conclusions, the TyG index was significantly associated with an increased risk of CKD in normoweight adults with hypertension, particularly in males and those with a history of alcohol consumption.

Difficult-to-Treat Axial Spondyloarthritis: A New Challenge.

Axial spondyloarthritis is a common form of chronic inflammatory rheumatic disease in adults, the treatment of which is based on non-pharmacological elements on the one hand, and pharmacological options on the other, such as non-steroidal anti-inflammatory drugs in the first line, followed by biological or targeted synthetic treatments. The therapeutic objective is remission or a low level of disease activity; if this objective is not achieved, the treatment is rotated or changed. Multiple changes is one factor illustrating the inability to achieve disease control and may lead to the notion of a difficult-to-treat disease (D2T). This requires a consensual definition including, beyond the number or therapeutic changes, the assessment of all the dimensions of the disease (objective signs of inflammation, residual pain, degenerative changes, psychosocial context). Recognising D2T patients will enable us to identify a particular population and the factors associated with this condition. When faced with a D2T disease, we need to analyse the causes of treatment failure and take into account the different components of the disease and the patient. In the absence of any prospect of new therapeutic targets in the short term for this disease, patient management may involve intensification of non-pharmacological means and evaluation of new therapeutic strategies such as combinations of targeted treatments.
