RESUMEN

AIMS: In China, more than 30% of patients have not initiated treatment within 30 days of HIV diagnosis. Delayed initiation has a detrimental influence on disease outcomes and increases HIV transmission. The study aims to evaluate the effectiveness of a nurse-led antiretroviral therapy initiation nudging intervention for people newly diagnosed with HIV in China to find the optimal intervention implementation strategy. METHODS: A Hybrid Type II sequential multiple assignment randomized trial will be conducted at four Centers for Disease Control and Prevention in Hunan, China. This study will recruit 447 people newly diagnosed with HIV aged ≥18 years and randomly assign them into two intervention groups and one control group. On top of the regular counselling services and referrals, intervention groups will receive a 4-week, 2-phase intervention based on the dual-system theory and the nudge theory. The control group will follow the currently recommended referral procedures. The primary outcomes are whether treatment is initiated, as well as the length of time it takes. The study outcomes will be measured at the baseline, day 15, day 30, week 12, week 24 and week 48. Generalized estimating equations and survival analysis will be used to compare effectiveness and explore factors associated with antiretroviral therapy initiation. Both qualitative and quantitative information will be collected to assess implementation outcomes. DISCUSSION: Existing strategies mostly target institutional-level factors, with little consideration given to patients' decision-making. To close this gap, we aim to develop an effective theory-driven nudging strategy to improve early ART initiation. IMPACT: This nurse-led study will help to prevent delayed initiation by employing implementation science strategies for people newly diagnosed with HIV. This study contributes to the United Nations' objective of ending the AIDS pandemic by 2030. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2300070140. The trial was prospectively registered before the first participant was recruited. PATIENT AND PUBLIC INVOLVEMENT: The nudging intervention was finalized through the Nominal Group Technique where we invited five experts in the related field and five people living with HIV to participate.

RESUMEN

Background: Sarcopenia, characterized by impaired muscle mass and function, is a common complication and the main reason for bad life quality and high mortality in chronic kidney disease (CKD). Limiting systemic inflammation is a potable intervention for sarcopenia. Dietary inflammatory potential can influence systemic inflammation. However, research about the association between dietary inflammatory potential and sarcopenia in CKD is limited. Aim: To investigate the association between dietary inflammatory potential and sarcopenia in the CKD population. Methods: We conducted a cross-section study based on the public database of the National Health and Nutrition Examination Survey (NHANES). In total, 2,569 adult CKD participants who had complete data for dietary inflammatory potential and sarcopenia were included. The dietary inflammatory potential was calculated by the dietary inflammation index (DII) score based on dietary recall interviews. We assessed sarcopenia via low skeletal muscle mass measured by dual-energy X-ray absorptiometry. Smooth curve fitting and a generalized linear mixed model were used to evaluate the relationship between DII and sarcopenia. Moreover, subgroup and sensitivity analyses were performed. Results: The overall prevalence of sarcopenia among patients with CKD is 19.11%. Smooth curve fitting results displayed that the DII score is near-linear positively associated with sarcopenia. Logistic regression confirmed sarcopenia is independently related to DII scores (odds ratio [OR], 1.17; 95% CI, 1.06-1.29). Subgroup analyses revealed relatively stronger associations between DII and sarcopenia among patients with CKD with other sarcopenia risk factors, such as hypoalbuminemia, low energy intake, low protein intake, and comorbidities. Conclusion: The dietary inflammatory potential is independently related to sarcopenia among patients with CKD. Anti-inflammatory diet patterns may be a protective intervention for CKD-associated sarcopenia.

RESUMEN

Different lines of evidence indicate that knowledge of low-glycemic index (GI) foods and the practice of eating them play important roles in blood glucose management and preventing T2DM in women with prior gestational diabetes mellitus (GDM). According to the theory of planned behavior (TPB), intention is a critical factor in complying with health-related behaviors. However, an instrument for assessing the intention to eat low-GI foods is lacking in China. We aimed to (1) adapt and validate a Chinese version of the intentions to eat low-GI foods questionnaire (CIELQ) and (2) apply the CIELQ among rural Chinese women to explore the associations between CIELQ scores and glycemic status. A cross-sectional study was conducted on 417 nondiabetic, nonpregnant participants with a history of GDM in Hunan, China. After cultural adaptation and validation, the CIELQ was applied in a target population. Glycemic status, anthropometric variables, dietary intake, and physical activity were measured; a self-developed, standard questionnaire was applied to collect relevant information. The CIELQ showed good internal consistency; model fitness was acceptable based on the confirmatory factor analysis results. Awareness of the glycemic index was low among the study population. TPB factors were found to be associated with each other; education level and parents' diabetes history were associated with specific factors. The score for instrumental attitude showed a positive association with the risk for a high level of the 2-h 75-g oral glucose tolerance test (odds ratio, OR = 1.330), while the score for perceived behavior control (PBC) showed a negative association with the risk for a high level (OR = 0.793). The CIELQ was determined to be a valid instrument for assessing the intention to eat a low-GI diet among the study population. The awareness of the GI was poor among the study population. The score for instrumental attitude showed a positive association with the risk of a high level on the 2-h 75-g oral glucose tolerance test (OGTT), and the score for PBC showed a negative association with the risk for a high level on OGTT.

RESUMEN

BACKGROUND: Assertive Community Treatment (ACT) is an evidence-based treatment program for people with severe mental illness developed in high-income countries. We report the first randomized controlled trial of ACT in mainland China. METHODS: Sixty outpatients with schizophrenia with severe functional impairments or frequent hospitalizations were randomly assigned to ACT (n = 30) or standard community treatment (n = 30). The severity of symptoms and level of social functioning were assessed at baseline and every 3 months during the 1-year study. The primary outcome was the duration of hospital readmission. Secondary outcomes included a pre-post change in symptom severity, the rates of symptom relapse and gainful employment, social and occupational functioning, and quality of life of family caregivers. RESULTS: Based on a modified intention-to-treat analysis, the outcomes for ACT were significantly better than those of standard community treatment. ACT patients were less likely to be readmitted [3.3% (1/30) v. 25.0% (7/28), Fisher's exact test p = 0.023], had a shorter mean readmission time [2.4 (13.3) v. 30.7 (66.9) days], were less likely to relapse [6.7% (2/30) v. 28.6% (8/28), Fisher's exact test p = 0.038], and had shorter mean time in relapse [3.5 (14.6) v. 34.4 (70.6) days]. The ACT group also had significantly longer times re-employed and greater symptomatic improvement and their caregivers experienced a greater improvement in their quality of life. CONCLUSION: Our results show that culturally adapted ACT is both feasible and effective for individuals with severe schizophrenia in urban China. Replication studies with larger samples and longer duration of follow up are warranted.

RESUMEN

Mercury is a major toxic metal ranked top in the Toxic Substances List. Cinnabar, which contains mercury sulfide, has been used in Chinese traditional medicines for thousands of years as an ingredient in various remedies, and 40 cinnabar-containing traditional medicines are still used today. Little is known about toxicology profiles or toxicokinetics of cinnabar and cinnabar-containing traditional medicines, and the high mercury content in these Chinese medicines raises justifiably escalations of public concern. This minireview, by searching the available database of cinnabar and by comparing cinnabar with common mercurials, discusses differences in their bioavailability, disposition, and toxicity. The analysis showed that cinnabar is insoluble and poorly absorbed from the gastrointestinal tract. Absorbed mercury from cinnabar is mainly accumulated in the kidneys, resembling the disposition pattern of inorganic mercury. Heating cinnabar results in release of mercury vapor, which in turn can produce toxicity similar to inhalation of these vapors. The doses of cinnabar required to produce neurotoxicity are 1000 times higher than methyl mercury. Following long-term use of cinnabar, renal dysfunction may occur. Dimercaprol and succimer are effective chelation therapies for general mercury intoxication including cinnabar. Pharmacological studies of cinnabar suggest sedative and hypnotic effects, but the therapeutic basis of cinnabar is still not clear. In summary, cinnabar is chemically inert with a relatively low toxic potential when taken orally. In risk assessment, cinnabar is less toxic than many other forms of mercury, but the rationale for its inclusion in traditional Chinese medicines remains to be fully justified.
