BACKGROUND Limited research has explored the impact of cardiovascular disease(CVD)on healthy life expectancy(HLE)especially in resource-limited areas.This study aimed to investigate the association between CVD and HLE in Chinese rural population.METHODS This study included 11,994 participants aged 45 years and older from the baseline and follow-up surveys of the Henan rural cohort study.Healthy status was measured via a Visual Analogue Scale.The multistate Markov model was applied to estimate the association between CVD and transitions in health,unhealthiness and death.Gender-specific total life expectancy,HLE and unhealthy life expectancy were calculated by the multistate life table method.RESULTS During a mean follow-up time of 3.85(3.84–3.86)years,there were 588 deaths recorded.For individuals with CVD,the risk of switching from health to unhealthiness status was increased by 71%[hazard ratio(HR)=1.71,95%CI:1.42–2.07],the chance of recovery was reduced by 30%(HR=0.70,95%CI:0.60–0.82).Men aged 45 years without CVD could gain an extra 7.08(4.15–10.01)years of HLE and lose 4.00(1.60–6.40)years of unhealthy life expectancy compared to their peers with CVD,respectively.The corresponding estimates among women were 8.62(5.55–11.68)years and 5.82(2.59–9.04)years,respectively.CONCLUSIONS This study indicated that CVD was significantly associated with poorer health status and lower HLE among Chinese rural population.It is an important public health policy to adopt targeted measures to reduce the CVD burden and enhance the quality of life and HLE in resource-limited areas. 展开更多

This is a risk factor for increased incidence of type 2 diabetes. There are few studies that have investigated the availability of low-sugar müsli products in grocery stores. Purpose: The study aims to identify which types of müsli contain high respectively low levels of sugar, and which brands are involved. Methods: The material consists of both qualitative interviews and observations from five grocery stores: City Gross, Hemköp, Ica Maxi, Stora Coop and Willy’s in Helsingborg, Sweden. The qualitative interviews had a semi-structured character and were recorded. The interviews took approx. 20 minutes and a textual analysis was conducted of the results. Data from observation was analyzed based on brand, nutritional composition and flavors, and also, where low sugar products were placed on store shelves. Results: The grocery stores provided together brands from AXA, Coop, Finax, Frebaco, Garant, ICA, Risenta, Saltå Kvarn och Urtekram, in total 24 müsli products. Of these products, 19 were high in sugar. The observation reveals that müsli products with high sugar content (17 - 29 g per 100 g müsli) are more prominently displayed than those with low sugar content. From the interviews with the store managers, it became clear that it would be valuable to highlight healthy müsli products on the shelves. However, central bureaucracy puts obstacles to such measures. Discussion: The study emphasizes the need for increased visibility of low-sugar products and proposes solutions such as negotiating with responsible person at the head office in Stockholm. Several reviews have shown that if the grocery store raises the prices of unhealthy food, the consumer is willing to purchase healthier müsli and other products. Conclusion: This study shows the need for grocery stores to upgrade healthy müsli products along with advertising to be able to influence customer’s shopping habits. Also, further research is needed how type 2 diabetes is affected by high intakes of food products with high sugar content. 展开更多

The aim of this study was to verify the existence of business and strategic intelligence policies at the level of Congolese companies and at the state level, likely to foster progress and healthy development in the east of the DRC. The study was based on a mixed perspective consisting of objective analysis of quantitative data and interpretative analysis of qualitative data. The results showed that business and strategic intelligence policies have not been established at either company or state level, as this is an area of activity that is not known to the players in companies and public departments, and there are no units or offices in their organizational structures responsible for managing strategic information for competitiveness on the international market. In addition, there is a real need to establish strategic information management units within companies, upstream, and to set up a national strategic information management department or agency to help local companies compete in the marketplace, downstream. This reflects the importance and timeliness of building business and strategic intelligence policies to ensure economic progress and development in the eastern DRC. Business and strategic intelligence provides companies with an appropriate tool for researching, collecting, processing and disseminating information useful for decision-making among stakeholders, in order to cope with a crisis or competitive situation. The study suggests a number of key recommendations based on its findings. To the government, it is recommended to establish the national policy of business and strategic intelligence by setting up a national agency of strategic intelligence in favor of local companies;and to companies to establish business intelligence units in their organizational structures in favor of stakeholders to foster advantageous decision-making in the competitive market and achieve progress. Finally, the study suggests that studies be carried out to fully understand the opportunities and impact of business and strategic intelligence in African countries, particularly in the DRC. 展开更多

Nursing students have uniqueness within the general university student population as they are among the primary practitioners of the “Healthy China Strategy 2030” and guardians of people’s health. Innovating and strengthening ideological and political education for nursing students, enhancing their skills in serving the people, is a significant political task for medical universities. Against the backdrop of the “Healthy China Strategy,” how to effectively improve nursing students’ professional competencies, integrate life education, medical humanities education, and general ideological and political education, and utilize life education to construct a more suitable ideological and political education system for nursing students, in order to better establish correct worldviews, values, and professional outlooks, are urgent practical issues that need to be addressed in ideological and political education in medical universities. This article takes life education as an entry point and focuses on integrating it with the internalization and unification of ideological and political education courses, aiming to explore the possibilities and new pathways for integrating life education into the ideological and political education of nursing students in the new era. 展开更多

Background: A balanced diet with a low glycemic index (GI) plays an important role in controlling and managing type 2 diabetes mellitus (T2DM). Here, we compared the GI of 2 flavors (vanilla and chocolate) of diabetes-specific nutritional (DSN) supplements to its comparator in healthy Indian adults under fasting conditions. Methods: This study was a 39-day open-label, non-comparative, single-center trial involving healthy adults aged between 18 to 45 years. The subjects received equal doses of 2 DSN powder (Treatments A and B), the comparator product (Treatment C), and dextrose monohydrate as a reference (Treatment R). Doses were administered as per the dosing schedule, after an overnight fast for 10 hours, with 2 intervening non-dosing days. Blood samples were collected on the dosing days to assess changes in capillary blood glucose levels. The primary endpoint of the study was the mean GI of Treatments A, B, and C (Defined as low: GI ≤ 55;medium: 55 GI ≤ 70;High: GI > 70), generated using the incremental area under the curve (AUC<sub>i</sub>) methodology. Safety was assessed throughout the study. Values of all study parameters were represented in ±SD or standard deviation. Results: Fourteen adult male subjects with a mean age of 29.42 ± 4.46 years, and a body mass index of 22.0 ± 1.95 Kg/m<sup>2</sup>, were enrolled in the study. The mean AUC<sub>i</sub> for treatments A, B, and C were 104 ± 10, 111 ± 12, and 87 ± 12 mmol min/L, respectively and for Treatment R it was 276 ± 16, 319 ± 28 and 338 ± 25 mmol min/L for Days 1, 6 and 8, respectively. The mean GI of Treatment A was 33 ± 3, Treatment B was 35 ± 3 and Treatment C was 29 ± 5;all GI means were ≤55. Mild adverse events were reported in 2 (14.3%) subjects. No serious adverse events or deaths were reported in the study. All treatments were well tolerated by the subjects. Conclusion: The glycemic index of both test products and comparator was low (i.e., GI 55) as per ISO 26642:2010 standard. 展开更多

Background: Although handgrip strength is a biomarker for morbidity/mor-tality, there is lack of evidence on the effects of resistance training on handgrip strength in healthy adults of all ages. Objective: The aim of this systematic review was to assess the impact of resistance training on handgrip strength in healthy adults. Methods: Five databases/search engines were searched. Studies comparing different types of resistance exercise interventions versus a non-exercised control group on handgrip strength were included. The available data did not allow us to conduct the pre-planned meta-analyses;therefore, only descriptive statistics were performed to summarize the data. Results: Twenty studies (17 randomized and three non-randomized controlled trials) were included, most of which were conducted in older adults. Twelve studies reported no significant difference in the change in handgrip strength between the resistance training and control groups. Two studies showed increases in handgrip strength in the resistance training group compared with the control group. Other studies included results for multi-training groups or left/right hands and found increasing handgrip strength compared to controls, but only in one training group or one hand. Overall, the randomized and non-ran-domized clinical trials presented moderate risk of bias. Conclusions: Due to the lack of low risk-of-bias randomized controlled trials of young and middle-aged adults, different training protocols, and small sample sizes, the existing evidence appears insufficient to support resistance training for increasing handgrip strength in healthy adults. Future studies may seek to discern the optimal way to develop and employ resistance training to improve hand-grip strength. 展开更多

Background: Spontaneous bilateral pneumothorax in healthy young adults is a rare and challenging condition that defies conventional diagnostic and etiological paradigms. This case report explores the presentation, diagnostic evaluation, management, and potential contributing factors in a 29-year-old male with no prior medical history who experienced bilateral spontaneous pneumothoraces. Aim: This case report aims to shed light on the complexities of managing spontaneous bilateral pneumothorax, particularly in the absence of common risk factors. It underscores the need for a thorough assessment and ongoing research to unravel the enigma surrounding this condition. Case Presentation: A healthy 29-year-old male presented with acute chest pain and shortness of breath, ultimately diagnosed with bilateral spontaneous pneumothoraces. Despite the absence of typical risk factors, advanced imaging techniques revealed valuable insights into the diagnosis and management of this unique presentation. Conclusion: Spontaneous bilateral pneumothorax in healthy individuals presents diagnostic challenges and raises questions about potential genetic predisposition, connective tissue disorders, and lifestyle-related triggers. While the acute phase was effectively managed, this case underscores the importance of interdisciplinary collaboration and ongoing research to comprehensively understand this condition. 展开更多

Based on the author's practice in river harnessing, this paper defines that a healthy river is a river whose social and natural functions can be balanced or compromised in terms of the socio-economic, ecological and environmental values associated with the river. The environmental values of river systems should be judged according to the following criteria: the signal of a healthy river should be associated with favorable riverbed, acceptable water quality, sustainable river ecosystem and compatible runoff. The river health criterion should reflect the river's natural function status which includes the riverbed, water quality, river ecosystem and runoff. But, the variety and quantity would be different for different rivers depending on different natural features and social background. The standards to be adopted for a healthy river should be determined according to the requirements for maintaining river's normal natural functions and the extent whether the social and natural functions could perform in a balanced way, and also the standards adopted should be adjusted according to the change of the given conditions. The key factor of river health is the enough and clean flow. The authors stressed that human activities would hurt the river health which include excessive water di- version and excessive power generation from the river, improper regulation of flood and sediment, and over discharge of sewage into the river and over change in fish habitat. Taking the Yellow River as a case, this paper also discussed the method to identify what are the standards of a healthy river as well as environmental flows. 展开更多

AIM: To evaluate the gastro-protective effect of capsaicin against the ethanol- and indomethacin (IND)-induced gastric mucosal damage in healthy human subjects. METHODS: The effects of small doses (1-8 μg/mL, 100 mL) of capsaicin on the gastric acid secretion basal acid output (BAO) and its electrolyte concentration, gastric transmucosal potential difference (GTPD), ethanol- (5 mL 300 mL/L i.g.) and IND- (3×25 mg/d) induced gastric mucosal damage were tested in a randomized, prospective study of 84 healthy human subjects. The possible role of desensitization of capsaicin-sensitive afferents was tested by repeated exposures and during a prolonged treatment. RESULTS: Intragastric application of capsaicin decreased the BAO and enhanced “non-parietal” component, GTPD in a dose-dependent manner. The decrease of GTPD evoked by ethanol was inhibited by the capsaicin application, which was reproducible. Gastric microbleeding induced by IND was inhibited by co-administration with capsaicin, but was not influenced by two weeks pretreatment with a daily capsaicin dose of 3×400μg i.g. CONCLUSION: Capsaicin in low concentration range protects against gastric injuries induced by ethanol or IND, which is attributed to stimulation of the sensory nerve endings. 展开更多
