Potassium-Enriched Salt Substitutes: A Review of Recommendations in Clinical Management Guidelines.

Excess dietary sodium intake and insufficient dietary potassium intake are both well-established risk factors for hypertension. Despite some successful initiatives, efforts to control hypertension by improving dietary intake have largely failed because the changes required are mostly too hard to implement. Consistent recent data from randomized controlled trials show that potassium-enriched, sodium-reduced salt substitutes are an effective option for improving consumption levels and reducing blood pressure and the rates of cardiovascular events and deaths. Yet, salt substitutes are inconsistently recommended and rarely used. We sought to define the extent to which evidence about the likely benefits and harms of potassium-enriched salt substitutes has been incorporated into clinical management by systematically searching guidelines for the management of hypertension or chronic kidney disease. We found incomplete and inconsistent recommendations about the use of potassium-enriched salt substitutes in the 32 hypertension and 14 kidney guidelines that we reviewed. Discussion among the authors identified the possibility of updating clinical guidelines to provide consistent advice about the use of potassium-enriched salt for hypertension control. Draft wording was chosen to commence debate and progress consensus building: strong recommendation for patients with hypertension-potassium-enriched salt with a composition of 75% sodium chloride and 25% potassium chloride should be recommended to all patients with hypertension, unless they have advanced kidney disease, are using a potassium supplement, are using a potassium-sparing diuretic, or have another contraindication. We strongly encourage clinical guideline bodies to review their recommendations about the use of potassium-enriched salt substitutes at the earliest opportunity.

Nutritional status and its determinants among adolescents with HIV on anti-retroviral treatment in low- and middle-income countries: a systematic review and meta-analysis.

PURPOSE: This review aimed to determine what methods are used to assess nutritional status, the levels of nutritional status, determinants of undernutrition, and nutritional interventions employed for adolescents with HIV on Anti-Retroviral Therapy follow-up in Low- and Middle-Income countries. METHODS: Established methods were used to systematically identify and retrieve studies published in five databases between January 2000 to May 2021, and citation searching. Quality was appraised and findings were synthesized using narrative analysis and meta-analysis. RESULT: Body Mass Index is the major indicator of nutritional status. The pooled prevalence of stunting, wasting, and overweight were 28.0%, 17.0%, and 5.0%, respectively. Adolescent males are 1.85 and 2.55 times more likely than adolescent females to suffer from both stunting and wasting at AOR = 1.85 (95%:1.47, 2.31) and AOR = 2.55 (95%: 1.88, 3.48), respectively. Similarly, adolescents with a history of opportunistic infections were 2.97 times more likely to be stunted than uninfected adolescents, AOR = 2.97 (95%:1.73, 5.12). One single intervention study found significant improvements in anthropometric status after nutritional supplementation. CONCLUSION AND RECOMMENDATION: The few studies that have been conducted on nutritional status in adolescents living with HIV in low- and middle-income countries indicate that stunting and wasting are common in this population. Avoiding opportunistic infections is an important protective factor but the review highlighted the generally inadequate and fragmented nature of nutritional screening and support programs. Development of comprehensive and integrated systems for nutritional assessment and intervention services during ART follow-up should be prioritized to improve adolescent clinical outcomes and survival.

The Joint Effects of Diet and Dietary Supplements in Relation to Obesity and Cardiovascular Disease over a 10-Year Follow-Up: A Longitudinal Study of 69,990 Participants in Australia.

It is unknown whether a healthy diet or unhealthy diet combined with specific supplements may jointly contribute to incidence of obesity and cardiovascular disease (CVD). We included 69,990 participants from the 45 and Up Study who completed both baseline (2006-2009) and follow-up (2012-2015) surveys. We found that compared to participants with a long-term healthy diet and no supplement consumption, those with a long-term healthy diet combined with multivitamins and minerals (MVM) or fish oil consumption were associated with a lower incidence of CVD (p < 0.001); whilst those with an unhealthy diet and no MVM or fish oil consumption were associated with a higher risk of obesity (p < 0.05). Compared to participants with a long-term healthy diet and no calcium consumption, the combination of a long-term healthy diet and calcium consumption was linked to a lower risk of CVD (IRR = 0.87, 95% CI: 0.78; 0.96). In conclusion, a long-term healthy diet combined with MVM or fish oil was associated with a lower incidence of CVD. Participants who maintained a healthy diet and used calcium supplements were associated with a lower incidence of obesity. However, these associations were not found among those with an unhealthy diet, despite taking similar supplements.

Biosynthesis of sorafenib coated graphene nanosheets for the treatment of gastric cancer in patients in nursing care.

Sorafenib (SRF) is a well-known tyrosine kinase inhibiting anticancer drug which iseffectual against multiple carcinomas especially gastric cancers by targeting the Ras/Raf/Mek/Erk cascade pathway and blocking the tumor cell proliferation. In the present work, we have reduced graphene oxide (GO) in presence of sorafenib using ascorbic as green reducing agent for the treatment of gastric cancers. Sorafenib reduced graphene oxide (SRGO) were obtained with a transparent and smoothmorphology. The drug loaded SRGO has presented significant cytotoxic effect against SGC7901 cancer cells when compared to that of the free SRF and blank NPs in the equivalent concentrations. Additionally, from the Hoechst 33382 staining study it was evident that the cells in untreated groups remained intact with its round shape and intact nuclei while the SRGO treated cells have shown a cell transformation with apoptosis of gastric cancer cell lines. Based on these results, we can conclude that SRGO might extend an enormous prospective in the treatment of gastric cancers.

Lifestyle Health Behaviors of Nurses and Midwives: The 'Fit for the Future' Study.

Nurses and midwives (nurses) are the principle role models and health educators for the wider population. This study sought to identify the health-related behaviors of the nursing workforce of New South Wales (NSW), Australia, compared to contemporary recommendations for healthy living and to the Australian general population, matched by gender and age. An electronic cross-sectional survey delivered in 2014⁻2015 recruited 5041 nurses through the NSW Nurses and Midwives Association and professional networks. Validated health behavior measures were collected and compared to Australian National Health Survey data. Compared with younger nurses, older nurses reported greater adherence to fruit and vegetable guideline recommendations, but were more likely to be overweight or obese. Younger nurses (25⁻34 years) had the highest risk of harmful drinking. Compared with the Australian general population, slightly higher percentages of nurses met dietary recommendations and slightly fewer were obese, had central adiposity or smoked. Nurses had lower physical activity levels and higher levels of risky drinking across most gender and age groups. Many nurses have lifestyle health behaviors that place them at high risk for developing non-communicable diseases, sometimes at higher risk than the Australian population to whom they deliver health education. Health promotion strategies for nurses are urgently required.

Factors influencing choice of skilled birth attendance at ANC: evidence from the Kenya demographic health survey.

BACKGROUND: In Kenya, skilled attendance at delivery is well below the international target of 90% and the maternal mortality ratio is high at 362 (CI 254-471) per 100,000 live births despite various interventions. The preventative role of skilled attendance at delivery makes it a benchmark indicator for safe motherhood. METHODS: Maternal health data from the Service Provision Assessment Survey, a subset of the 2010 Kenya Demographic Health Survey was analyzed. Logistic regression models were employed using likelihood ratio test to explore association between choice of skilled attendance and predictor variables. RESULTS: Overall, 94.8% of women are likely to seek skilled attendance at delivery. Cost, education level, number of antenatal visits and sex of provider were strongly associated with client's intention to deliver with a skilled birth attendant at delivery. Women who reported having enough money set aside for delivery were 4.34 (p < 0.002, 95% CI: 1.73; 10.87) times more likely to seek skilled attendance. Those with primary education and above were 6.6 times more likely to seek skilled attendance than those with no formal education (p < 0.001, 95% CI: 3.66; 11.95). Women with four or more antenatal visits were 5.95 (p < 0.018, 95% CI: 1.35; 26.18) times more likely to seek skilled attendance. Compared to men, female providers impacted more on the client's plan (OR = 2.02 (p < 0.014, 95% CI: 1.35; 3.53). CONCLUSION: Interventions aimed at improving skilled attendance at delivery should include promotion of formal education of women and financial preparation for delivery. Whenever circumstances permit, women should be allowed to choose gender of preferred professional attendant at delivery.

Does nurses' role, health or symptoms influence their personal use of ingestible complementary and alternative medicines?

OBJECTIVES: To investigate the influence of work-related characteristics, health, health behaviours and symptoms on ingestible biologically-based Complementary and Alternative Medicine (CAM) use within the Australian nursing and midwifery workforce. BACKGROUND: CAM use is widespread worldwide, but there is little research into nurses' and midwives' personal use of ingestible CAM in Australia. METHODS: An online survey in 2014-15 used validated instruments and items to examine use of ingestible biologically-based CAM (herbs, foods and vitamins, minerals, amino acids, enzymes and other supplements), and the health and work-related characteristics of 5041 nurses and midwives recruited through the New South Wales Nurses and Midwives Association and professional networks. RESULTS: A small proportion of nurses (6.8%) identified as personal CAM users. Most were female, older, worked in foundational roles (frontline Registered and Enrolled Nurses/Midwives) and used one CAM, most commonly a multivitamin, although Vitamin D, Fish Oil, Calcium and Glucosamine±Chondroitin were also common. In comparison to non-users, CAM users were less likely to take sick days or indulge in risky drinking, but more likely to be symptomatic (with stiff joints, bodily/joint pain, severe tiredness, allergies, indigestion/heartburn), diagnosed with osteoarthritis and to adhere to healthy diet recommendations. CONCLUSIONS: Findings showed a credible pattern of front line workers with physically demanding workloads that impact their physical health and are linked to frequent symptoms, using CAM treatments and achieving some success in being able to continue working and avoid sickness absence. Further investigation is warranted to protect and maintain the health of the nursing and midwifery workforce.

Dietary pattern, serum magnesium, ferritin, C-reactive protein and anaemia among older people.

BACKGROUND & AIMS: Epidemiological data of dietary patterns and anaemia among older Chinese remains extremely scarce. We examined the association between dietary patterns and anaemia in older Chinese, and to assess whether biomarkers of serum magnesium, C-reactive protein (CRP) and serum ferritin can mediate these associations. METHODS: We analysed the 2009 China Health and Nutrition Survey data (2401 individuals aged ≥60 years for whom both dietary and biomarker data are available). Dietary data was obtained using 24 h-recall over three consecutive days. Fasting blood samples and anthropometry measurement were also collected. Factor analysis was used to identify dietary patterns. Factor scores representing dietary patterns were used in Poisson regression models to explore the association between each dietary pattern and anaemia. RESULTS: Of the 2401 participants, 18.9% had anaemia, 1.9% had anaemia related to inflammation (AI), and 1.3% had iron-deficiency anaemia (IDA). A traditional dietary pattern (high intake of rice, pork and vegetables) was positively associated with anaemia; a modern dietary pattern (high intake of fruit and fast food) was inversely associated with anaemia. Progressively lower magnesium and BMI levels were associated with increasing traditional dietary quartiles; while a progressively higher magnesium and BMI levels were associated with increasing modern dietary quartiles (p < 0.001). There were no significant differences (p > 0.05) in CRP and serum ferritin across quartiles for either dietary pattern. In the fully adjusted model, the prevalence ratio (PR) of anaemia, comparing the fourth quartile to the first quartile, was 1.75 (95% CI: 1.33; 2.29) for a traditional dietary pattern, and 0.89 (95% CI: 0.68; 1.16) for a modern dietary pattern. The association between dietary patterns and anaemia is mediated by serum magnesium. CONCLUSION: Traditional dietary pattern is associated with a higher prevalence of anaemia among older Chinese. Future studies need to examine whether correcting micronutrient deficiency (e.g. magnesium) by promoting overall healthy diet, rather than iron supplementation, is a suitable strategy for anaemia prevention in older Chinese people.

Differences in depression between unknown diabetes and known diabetes: results from China health and retirement longitudinal study.

BACKGROUND: Both diabetes and depression have become serious public health problems and are major contributors to the global burden of disease. People with diabetes have been shown to have higher risk of depression. The purpose of this study was to observe the differences in depression between older Chinese adults with known or unknown diabetes. METHODS: Data came from the national baseline survey of China Health and Retirement Longitudinal Study (CHARLS). The Center for Epidemiologic Studies Depression Scale was used to assess depression. Participants with a history of diabetes diagnosis were considered to have known diabetes, and those with newly-diagnosed diabetes were considered to have unknown diabetes. Multiple logistic regression analysis was applied to estimate odds ratio (OR) for depression in predictor variables. RESULTS: Overall, 39.1% of the 2,399 participants with diabetes suffered from depression. The prevalence of depression was significantly higher (p < 0.001) in people with known diabetes (43.5%) than those with unknown diabetes (35.1%). The biggest differences between the two groups were found in the middle aged, in women, in the less educated and in married people. In known diabetes, people treated with traditional Chinese medicine (TCM) coupled with oral western medicine (WM) and/or insulin had two-fold odds of depression compared to those without treatment. CONCLUSION: The knowledge of having diabetes, treatments and suffering from other chronic diseases were associated with the higher prevalence of depression in people with known diabetes compared to those with unknown diabetes. Prevention of depression in diabetics should receive more attention in the middle aged, women and the less education.
