Barriers to accessing care for cardiometabolic disorders in Malawi: partners as a source of resilience for people living with HIV

BACKGROUND

People living with HIV (PLWH) are at increased risk of cardiometabolic disorders (CMD). Adequate access to care for both HIV and CMD is crucial to improving health outcomes; however, there is limited research that have examined couples' experiences accessing such care in resource-constrained settings. We aimed to identify barriers to accessing CMD care among PLWH in Malawi and the role of partners in mitigating these barriers.

METHODS

We conducted a qualitative investigation of barriers to CMD care among 25 couples in Malawi. Couples were eligible if at least one partner was living with HIV and had hypertension or diabetes (i.e., the index patient). Index patients were recruited from HIV care clinics in the Zomba district, and their partners were enrolled thereafter. Interviews were conducted separately with both partners to determine barriers to CMD care access and how partners were involved in care.

RESULTS

Participants framed their experiences with CMD care by making comparisons to HIV treatment, which was free and consistently available. The main barriers to accessing CMD care included shortage of medications, cost of tests and treatments, high cost of transportation to health facilities, lengthy wait times at health facilities, faulty or unavailable medical equipment and supplies, inadequate monitoring of patients' health conditions, some cultural beliefs about causes of illness, use of herbal therapies as an alternative to prescribed medicine, and inadequate knowledge about CMD treatments. Partners provided support through decision-making on accessing medical care, assisting partners in navigating the healthcare system, and providing financial assistance with transportation and treatment expenses. Partners also helped manage care for CMD, including communicating health information to their partners, providing appointment reminders, supporting medication adherence, and supporting recommended lifestyle behaviors.

CONCLUSIONS

Couples identified many barriers to CMD care access, which were perceived as greater challenges than HIV care. Partners provided critical forms of support in navigating these barriers. With the rise of CMD among PLWH, improving access to CMD care should be prioritized, using lessons learned from HIV and integrated care approaches. Partner involvement in CMD care may help mitigate most barriers to CMD care.

Improved glycemic control either alone, or combined with antioxidant supplementation, fails to restore blood glutathione or markers of oxidative stress in adolescents with poorly controlled type 1 diabetes

In earlier studies, we showed that adolescents with type 1 diabetes mellitus (T1DM) have significant glutathione (GSH) depletion and that GSH is reciprocally related to glycemic control. In both the general population and in those with diabetes, the use of over-the-counter antioxidant supplements is widespread. We hypothesized that improved glycemic control, alone or in combination with dietary antioxidants, would restore blood GSH pool. The study included 41 participants who were 15.8 ± 2.4 years of age (mean ± standard deviation) and with poorly controlled T1DM (hemoglobin A1c [HbA1c] 8.2 ± 0.6%). Erythrocyte GSH, and 3-nitrotyrosine, F2-isoprostane, and 8-hydroxy-2'-deoxy-guanosine (as markers of protein, lipid, and DNA oxidative stress, respectively) were determined in the postabsorptive state after blood glucose was maintained overnight near euglycemia. Participants were then randomized to a mix of antioxidants (vitamin C, selenium, zinc, vitamin E, β-carotene) or placebo for 3 to 6 months, and diabetes management was intensified using CSII (n = 30) or multiple daily injections (n = 11) coupled with CDE phone calls and visits with a Nutritionist. A second, identical study was performed when/if a drop in HbA1c ≥0.5% was achieved. HbA1c levels dropped similarly in both groups (from 8.9 ± 1.0% to 7.9 ± 0.9% and 8.5 ± 0.6% to 7.7 ± 0.7% in placebo and antioxidant group, respectively). Neither total nor reduced GSH was altered by improved metabolic control. Markers of protein, lipid, and DNA oxidation remained unaltered. We conclude that, in youngsters with T1DM, neither a significant improvement in diabetes control over a 3-month period nor the regimen of dietary antioxidant supplied in the current study can mitigate oxidative stress. These findings suggest that, in adolescents with T1DM, (1) more sustained improvement of diabetes control may be needed to alleviate oxidative stress and (2) the putative benefit of antioxidant supplements remains to be proven.

Investigating the effects of Ceylon cinnamon water extract on HepG2 cells for Type 2 diabetes therapy

Cinnamon and its extracts have been used as herbal remedies for many ailments, including for reducing insulin resistance and diabetes complications. Type 2 diabetes mellitus (T2DM) is a rapidly growing health concern around the world. Although many drugs are available for T2DM treatment, side effects and costs can be considerable, and there is increasing interest in natural products for managing chronic health conditions. Cinnamon may decrease the expression of genes associated with T2DM risk. The purpose of this study was to evaluate the effects of cinnamon water extract (CWE) compared with metformin on T2DM-related gene expression. HepG2 human hepatoma cells, widely used in drug metabolism and hepatotoxicity studies, were treated with different concentrations of metformin or CWE for 24 or 48 h. Cell viability was assessed by MTT (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) assay and glucose uptake was compared in untreated and CWE- or metformin-treated cells under high-glucose conditions. Finally, total RNA was extracted and analyzed by RNA sequencing (RNA-seq), and bioinformatics analyses were performed to compare the transcriptional effects of CWE and metformin. We found cell viability was better in cells treated with CWE than in metformin-treated cells, demonstrating that CWE was not toxic at tested doses. CWE significantly increased glucose uptake in HepG2 cells, to the same degree as metformin (1.4-fold). RNA-seq data revealed CWE and metformin both induced significantly increased (1.3- to 1.4-fold) glucose uptake gene expression compared with untreated controls. Transcriptional differences between CWE and metformin were not significant. The effects of 0.125 mg mL^-1 CWE on gene expression were comparable to 1.5 mg mL^-1 (9.5 mM) metformin. In addition, gene expression at 0.125 mg mL^-1 CWE was comparable to 1.5 mg mL^-1 (9.5 mM) metformin. Our results reveal that CWE's effects on cell viability, glucose uptake, and gene expression in HepG2 cells are comparable to those of metformin, suggesting CWE may be an effective dietary supplement for mitigating T2DM-related metabolic dysfunction.

The Effect of Herbal Product Use on BMI and HbA1c in Patients with Diabetes

Aim: Patients with diabetes can use herbal products to better manage the disease. The aim of this study is to examine the rate of herbal product use and the effect of herbal product use on Body Mass Index (BMI) and hemoglobin A1c (HbA1c) values in patients with diabetes.Method: The descriptive and cross-sectional study was conducted in the diabetes outpatient clinic of a hospital in Istanbul with a total of 104 patients with diabetes. The data were collected using a data collection form, which questioned the patients' socio-demographic characteristics, disease information and herbal product use. Data analysis was performed using Chi-square, One-Sample Kolmogorov-Smirnov test and Mann Whitney U test in computer environment.Results: The mean age of patients with diabetes was 61,08±9,3 years, the mean BMI was 26,3±5,4kg/m², and the mean HbA1c value was 6,9%±1,8%. The BMI and HbA1c values of the patients using herbal products were lower than the patients not using herbal products (respectively; p=,002; p=,047). It was determined that the duration of herbal product use did not affect BMI and HbA1c values (p>,05).Conclusion: The use of herbal products was high in patients with diabetes. It was determined that olive leaf, cinnamon leaf, thyme juice, garlic, black sesame, blueberry, fenugreek seeds, French lavender and bitter almond were used as herbal products. Herbal product use decreased BMI and HbA1c values.

Complementary and alternative medicine for glycemic control of diabetes mellitus: A systematic review

The use of complementary and alternative medicine (CAM) is increasingly popular for the management of diabetes mellitus (DM). The aim of this study was to conduct systematic review of any types of complementary and alternative medicine for glycemic control of diabetes mellitus. Four databases was used in this study, the CINAHL, PUBMED, SCOPUS, and ProQUEST. The systematic review were reported according to the PRISMA guidelines. The keywords were used according to medical subject headings (MeSH) in this study were diabetes mellitus AND complementary and alternative medicine AND blood glucose levels or blood sugar or blood glucose. Articles were limited to 2015–2021 and only in English language. We obtained 231 articles from these databases: CINAHL six articles, PUBMED 85 articles, SCOPUS 66 articles, PROQUEST 74 articles. Then, the final results recorded 17 articles. The results of a systematic review showed the effectiveness of natural products as CAM for glycemic control of DM, namely Berberis aristata/Silybum marianum, fenugreek seed, bitter melon, cinnamon or whortleberry supplements, a combination of herbal plants (C. spinosa, R. canina, and S. securigera), Nigella sativa, Mulberry juice, chicory, chamomile tea, and bell pepper juice combined with an integrated approach of yoga therapy. Mind body practices such as auditory guided imagery (AGI), qigong and tai chi exercises, and relaxation. Whole system approach, such as acupressure. Health care providers consider CAM for DM management.

Orally consumed ginger and human health: an umbrella review

BACKGROUND

Emerging evidence supports the health benefits of ginger for a range of conditions and symptoms; however, there is a lack of synthesis of literature to determine which health indications are supported by quality evidence.

OBJECTIVES

In this umbrella review of systematic reviews we aimed to determine the therapeutic effects and safety of any type of ginger from the Zingiber family administered in oral form compared with any comparator or baseline measures on any health and well-being outcome in humans.

METHODS

Five databases were searched from inception to April 2021. Review selection and quality were assessed in duplicate using the Assessment of Multiple Systematic Reviews-2 (AMSTAR-2) checklist and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) method, with results presented in narrative form.

RESULTS

Twenty-four systematic reviews were included with 3% overlap of primary studies. The strongest evidence was found for the antiemetic effects of ginger in pregnant women (effect size: large; GRADE: high), analgesic effects for osteoarthritis (effect size: small; GRADE: high), and glycemic control (effect size: none to very large; GRADE: very low to moderate). Ginger also had a statistically significant positive effect on blood pressure, weight management, dysmenorrhea, postoperative nausea, and chemotherapy-induced vomiting (effect size: moderate to large; GRADE: low to moderate) as well as blood lipid profile (effect size: small; GRADE: very low) and anti-inflammatory and antioxidant biomarkers (effect size: unclear; GRADE: very low to moderate). There was substantial heterogeneity and poor reporting of interventions; however, dosage of 0.5-3 g/d in capsule form administered for up to 3 mo was consistently reported as effective.

CONCLUSIONS

Dietary consumption of ginger appears safe and may exert beneficial effects on human health and well-being, with greatest confidence in antiemetic effects in pregnant women, analgesic effects in osteoarthritis, and glycemic control. Future randomized controlled and dose-dependent trials with adequate sample sizes and standardized ginger products are warranted to better inform and standardize routine clinical prescription.

Perception of Individuals with Diabetes about Efficacy and Safety of Complementary and Alternative Medicines (CAM) in the Jazan Region, Saudi Arabia

Background

CAM is widely accepted for the management of diabetes, and CAM users from many countries showed positive perception towards its use. However, little is known about the perception of individuals with diabetes in Saudi Arabia.

Objectives

This study was aimed to assess the perception of the individuals with diabetes of Jazan region in Saudi Arabia towards CAM.

Methods

An online, anonymous cross-sectional survey was designed and conducted between September 5 and December 31, 2021. Data were collected using 19-item self-report survey from the individuals with diabetes of the Jazan region.

Results

A total of 359 validated responses were received. Approximately, 34% of the participants reported using CAM with modern medicine to control diabetes. Most of the participants reported that CAM is affordable, accessible, acceptable, and effective. Of the study sample, 28% reported using herbal medicine to control diabetes. Significantly, higher percentages of CAM users reported media (42% vs 27%) and friends/family (31% vs 27%) as the primary sources of information about CAM as compared to non-CAM users. Individuals who used CAM for diabetes showed significantly more positive perception (β = 2.386; p=0.001) than those who did not use CAM in the adjusted analysis. Similarly, students had a significantly higher positive perception towards CAM (β = 4.121; p=0.013) compared to employed individuals.

Conclusion

A quarter of the sample of individuals with diabetes used herbal medicine to control diabetes. Individuals who ever used CAM for diabetes showed positive perception towards CAM. However, there is a need of healthcare workers to be involved in educating the individuals with diabetes and the general public in order to use CAM more effectively and safely.

Efficacy of Residential, Group-Based, Intensive Holistic Lifestyle Intervention Among Type-2 Diabetes Patients - A Single Group Pre- And Post-intervention Study

Background

The present study assessed the efficacy of the residential, group-based, intensive holistic lifestyle intervention on glycaemic control.

Materials and methods

A one-group pre and post-intervention study was conducted among 145 people with diabetes for a period of one year from February 2019 to January 2020. The study population underwent "Brahma Kumaris Raja Yoga lifestyle" intervention. Outcome variables were changes in HbA1c levels and anthropometric parameters (like weight, BMI, etc.). Paired t-test was used to compare normally distributed numeric variables.

Results

The mean age was 52.39±5.79 years, with a male-female ratio close to 1:1. Mean HbA1c at baseline was 9.06±2.1%. The mean weight and BMI were 71.03±12.84 kg and 28.28±4.83kg/m², respectively. Mean HbA1c value had shown a reduction of 1.60% (95%CI 1.17 to 1.90, p <0.001) at three months and 1.58% (95% CI 1.13-1.87, p<0.001) reduction at a six-month follow-up. Between the third and sixth months, there was no significant change in the HbA1c value. Mean weight reduced by 0.79 kg (95% CI 0.08-1.08, p=0.023) at six-month follow-up and mean BMI decreased by 0.31 units from baseline to three months (95% CI 0.05-0.56, p=0.017). A statistically significant reduction was observed in waist circumference at the third month (MD=1.61 95% CI =0.95 to 2.28, P<0.001) and sixth month (MD=1.53, 95% CI 0.82-2.25, p<0.001) follow-up.

Conclusion

This residential, group-based, intensive holistic lifestyle intervention showed a significant decrease in HbA1c levels and anthropometric parameters at three- and six-months follow-up, thereby improving the overall health and wellbeing of people with diabetes.

Diabetes mellitus and COVID-19: review of a lethal interaction from the cellular and molecular level to the bedside

INTRODUCTION

While the main mode of transmission of coronavirus disease 2019 (COVID-19) is close contact with other individuals, the presence of chronic underlying diseases such as Diabetes Mellitus (DM) increases the chance of hospitalization and mortality rate due to infection.

AREAS COVERED

To investigate the effects of COVID-19 infection in DM patients, we reviewed literature from Google Scholar search engine and PubMed database from '2013 to 2020' using the terms "COVID-19; SARS-CoV-2; Diabetes mellitus; obesity; Angiotensin-converting enzyme 2; ACE2; Insulin and Metformin. Evidence suggests that COVID-19 exacerbates the course of diabetes. Presence of pro-inflammatory conditions, increased expression of receptors, and more difficult control of glucose levels in diabetics COVID-19 patients are some of the problems that diabetic patients may face. Also, psychological problems caused by the COVID-19 epidemic in diabetic patients is one of the most important problems in these patients, which is less covered.

EXPERT OPINION

DM is a strong and independent risk factor with a poor prognosis, which increases the risk of COVID-19 infection, the need for emergency services, the rate of hospitalization in the intensive care unit and also increases the mortality rate of COVID-19 patients.

Development of a nursing assessment form for patients with diabetes mellitus in a hospital: A research and development study

Background

People with Diabetes Mellitus (DM) tend to seek herbal medicine or complementary drugs in their treatments. But, unfortunately, the existing nursing assessment forms have not prepared the format for the use of complementary medicine.

Objective

This study aimed to develop a nursing assessment form in patients with DM based on the Chronic Care Model (CCM) approach.

Methods

This study employed a Research and Development study design, which consists of ten stages. The nursing assessment form was developed based on CCM theory and integrated complementary medicines into the assessment form. A content validity test was done by four experts and calculated using Aiken's V formula. Face validity among 12 nurses through Focus Group Discussions (FGDs) was also employed to test the quality of the nursing assessment form based on three aspects: functionality, efficiency, and usability. In addition, nine nurses were included for pilot testing of the form. Data were analyzed using descriptive analysis.

Results

The nursing assessment form demonstrated a good content validity, with Aiken's V value of 0.94. The form was categorized based on four components of CCM: self-management support, decision support, social activities, and clinical information. Additionally, all nurses could fill the form properly.

Conclusion

The nursing assessment form is valid. It can be used for nurses to assess patients with DM based on the CCM with an additional component to evaluate the use of complementary medicine.

Quality of complementary and alternative medicine information for type 2 diabetes: a cross-sectional survey and quality assessment of websites

BACKGROUND

The global prevalence of diabetes mellitus is projected to reach approximately 700 million by the year 2045, with roughly 90-95% of all diabetes cases being type 2 in nature. Patients with type 2 diabetes mellitus (T2DM) frequently seek information about complementary and alternative medicine (CAM) online. This study assessed the quality of publicly accessible websites providing consumer health information at the intersection of T2DM and CAM.

METHODS

An online search engine (Google) was searched to identify pertinent websites containing information specific to CAM for T2DM patients, and the relevant websites were then screened with an eligibility criteria. Consumer health information found on eligible websites were then assessed for quality using the DISCERN instrument, a 16-item standardized scoring system.

RESULTS

Across the 480 webpages identified, 94 unique webpages remained following deduplication, and 37 eligible webpages belonged to and were collapsed into 30 unique websites that were each assessed using the DISCERN instrument. The mean overall quality score (question 16) across all 30 assessed websites was 3.55 (SD = 0.86), and the mean summed DISCERN score was 52.40 (SD = 12.11). Eighty percent of websites presented a wide range of CAM treatment options with the associated benefits/risks of each treatment, but in 56.7% of the websites, the sources used to collect information were unreliable.

CONCLUSION

This study identified, assessed, and presents findings on the quality of online CAM information for T2DM. Although there were several high scoring websites, there was variability across most of the individual DISCERN items in the assessed websites. This study highlights the importance of awareness among healthcare providers regarding the reliability of online information about CAM treatment and management options for T2DM. Healthcare providers should be aware of patients' information seeking behaviour, guide them in navigating through the content they encounter online, and provide them with resources containing trustworthy and reliable information.

Pharmaceutical Drugs and Natural Therapeutic Products for the Treatment of Type 2 Diabetes Mellitus

Type 2 diabetes mellitus (T2DM) is the most widespread form of diabetes, characterized by chronic hyperglycaemia, insulin resistance, and inefficient insulin secretion and action. Primary care in T2DM is pharmacological, using drugs of several groups that include insulin sensitisers (e.g., biguanides, thiazolidinediones), insulin secretagogues (e.g., sulphonylureas, meglinides), alpha-glucosidase inhibitors, and the newest incretin-based therapies and sodium-glucose co-transporter 2 inhibitors. However, their long-term application can cause many harmful side effects, emphasising the importance of the using natural therapeutic products. Natural health substances including non-flavonoid polyphenols (e.g., resveratrol, curcumin, tannins, and lignans), flavonoids (e.g., anthocyanins, epigallocatechin gallate, quercetin, naringin, rutin, and kaempferol), plant fruits, vegetables and other products (e.g., garlic, green tea, blackcurrant, rowanberry, bilberry, strawberry, cornelian cherry, olive oil, sesame oil, and carrot) may be a safer alternative to primary pharmacological therapy. They are recommended as food supplements to prevent and/or ameliorate T2DM-related complications. In the advanced stage of T2DM, the combination therapy of synthetic agents and natural compounds with synergistic interactions makes the treatment more efficient. In this review, both pharmaceutical drugs and selected natural products, as well as combination therapies, are characterized. Mechanisms of their action and possible negative side effects are also provided.

Oral Administration of Gongronema latifolium Leaf Extract Modulates Gut Microflora and Blood Glucose of Induced Diabetic Rats

Studies have suggested that modulation of gut microbiota is a viable therapeutic possibility for diabetes. This study evaluated the ability of an edible plant, Gongronema (G.) latifolium Benth (Asclepiadaceae), to modulate the gut microbiome and reduce blood glucose of alloxan-induced diabetic rats. Thirty (30) young, male, albino rats were divided into 6 groups of 5 rats each: Group 1 comprised normal rats; Groups 2 to 4, diabetic rats treated with 200, 400 and 800 mg/Kg body weight of hydro-alcoholic leaf extract, respectively; Group 5, diabetic rats treated with 0.2 mg/Kg glibenclamide (an anti-diabetic drug); and Group 6 comprised untreated diabetic rats. Following induction of diabetes with alloxan injections, the treatments were administered twice daily on a 12-hourly basis by orogastric intubation for 21 days. Thereafter, faecal samples were collected from the animals and subjected to metagenomic analysis, to ascertain the composition and relative abundance of the gut microbiota. There were five dominant bacterial phyla in the rat gut: Firmicutes, Bacteroidetes, Actinobacteria, Spirochaetea and Proteobacteria. Induction of diabetes resulted in observable dysbiosis in the rats. However, treatment of the diabetic rats with G. latifolium extract, ameliorated the state of dysbiosis and resulted in significant increase in species like Lactobacillus (L.) johnsonii, L. reuteri and Prevotella corpri, which are associated with improved glucose metabolism. The plant extract produced the best result at the dose of 400 mg/Kg. The results from this study show that G. latifolium may be used as a therapeutic option for restoration of the microbiome in diabetic patients.

Co-administration of viscous fiber, Salba-chia and ginseng on glycemic management in type 2 diabetes: a double-blind randomized controlled trial

PURPOSE

Viscous dietary fiber, functional seeds and ginseng roots have individually been proposed for the management of diabetes. We explored whether their co-administration would improve glycemic control in type 2 diabetes beyond conventional therapy.

METHODS

In a randomized, double-blind, controlled trial conducted at two academic centers (Toronto, Canada and Zagreb, Croatia), individuals with type 2 diabetes were assigned to either an active intervention (10 g viscous fiber, 60 g white chia seeds, 1.5 g American and 0.75 g Korean red ginseng extracts), or energy and fiber-matched control (53 g oat bran, 25 g inulin, 25 g maltodextrose and 2.25 g wheat bran) intervention for 24 weeks, while on conventional standard of care. The prespecified primary endpoint was end difference at week 24 in HbA1c, following an intent-to-treat analysis adjusted for center and baseline.

RESULTS

Between January 2016 and April 2018, 104 participants (60M:44F; mean ± SEM age 59 ± 0.8 years; BMI 29.0 ± 0.4 kg/m²; HbA1c 7.0 ± 0.6%) managed with antihyperglycemic agent(s) (n = 98) or lifestyle (n = 6), were randomized (n = 52 test; n = 52 control). At week 24, HbA1c levels were 0.27 ± 0.1% lower on test compared to control (p = 0.03). There was a tendency towards an interaction by baseline HbA1c (p = 0.07), in which a greater reduction was seen in participants with baseline HbA1c > 7% vs ≤ 7% (- 0.56 ± 0.2% vs 0.03 ± 0.2%). Diet and body weight remained unchanged. The interventions were well tolerated with no related adverse events and with high retention rate of 84%.

CONCLUSIONS

Co-administration of selected dietary and herbal therapies was well-tolerated and may provide greater glycemic control as add-on therapy in type 2 diabetes. Registration: Clinicaltrials.gov NCT02553382 (registered on September 17, 2015).

Protective effects of a standardized extract of Iris germanica on pancreas and liver in streptozotocin-induced diabetic rats

Background and purpose:

Previous studies have shown the antioxidant, anti-inflammatory, immunomodulatory, and hypolipidemic activities of Iris germanica. The aim of the present study was to evaluate the protective effects of hydroalcoholic extract of Iris germanica rhizomes on streptozotocin-induced diabetic rats.

Experimental approach:

Twenty-four male Wistar rats were randomly assigned into four groups including a normal control group, diabetic control group, diabetic groups treated for 4 weeks with 100 and 200 mg/kg/day of the Iris germanica extract (IGE).

Findings/Results:

Induction of diabetes significantly decreased the body weight gain and considerably increased the serum levels of glucose, triglyceride, blood urea nitrogen (BUN), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). Diabetes also diminished the antioxidant capacity of the liver (decrease of thiol groups) and significantly degenerated pancreatic islands. The IGE at both doses of 100 and 200 mg/kg significantly reduced the levels of glucose, triglyceride, AST, ALT, and ALP. Moreover, IGE increased the total antioxidant capacity of the liver and ameliorated pancreatic island morphology. The extract had no significant effect on body weight and BUN level.

Conclusion and implication:

These findings suggest that Iris germanica rhizomes inhibits the progression of hyperglycemia and hypertriglyceridemia and has protective effects against diabetes-induced injury of the liver and pancreas. Therefore, this plant has the potential to be used as a natural product for controlling diabetes.

Effect of camel milk protein hydrolysates against hyperglycemia, hyperlipidemia, and associated oxidative stress in streptozotocin (STZ)-induced diabetic rats

This study investigated the effect of camel milk protein hydrolysates (CMPH) at 100, 500 and 1,000 mg/kg of body weight (BW) for 8 wk on hyperglycemia, hyperlipidemia, and associated oxidative stress in streptozotocin-induced diabetic rats. Body weights and fasting blood glucose levels were observed after every week until 8 wk, and oral glucose tolerance test (OGTT) levels and biochemical parameters were evaluated after 8 wk in blood and serum samples. Antioxidant enzyme activity and lipid peroxidation in the liver were estimated, and histological examination of the liver and pancreatic tissues was also conducted. Results showed that CMPH at 500 mg/kg of BW [camel milk protein hydrolysate, mid-level dosage (CMPH-M)] exhibited potent hypoglycemic activity, as shown in the reduction in fasting blood glucose and OGTT levels. The hypolipidemic effect of CMPH was indicated by normalization of serum lipid levels. Significant improvement in activity of superoxide dismutase and catalase, and reduced glutathione levels were observed, along with the attenuation of malondialdehyde content in groups fed CMPH, especially CMPH-M, was observed. Decreased levels of liver function enzymes (aspartate aminotransferase and alanine aminotransferase) in the CMPH-M group was also noted. Histology of liver and pancreatic tissue displayed absence of lipid accumulation in hepatocytes and preservation of β-cells in the CMPH-M group compared with the diabetic control group. This is the first study to report anti-hyperglycemic and anti-hyperlipidemic effect of CMPH in an animal model system. This study indicates that CMPH can be suggested for its therapeutic benefits for hyperglycemia and hyperlipidemia, thus validating its use for better management of diabetes and associated comorbidities.

Herbal medicine from the perspective of type II diabetic patients and physicians: what is the relationship?

Background

Diabetes mellitus (DM) is a major public health problem and one of the most challenging diseases worldwide. According to the World Health Organization (WHO), the Kingdom of Saudi Arabia (KSA) has the second highest rate of diabetes in the Middle East and seventh highest globally. Some diabetic patients may prefer to use alternative approaches such as herbal remedies to control their blood glucose level and this study aims to assess the prevalence of herbal usage and to evaluate users’ and doctors’ knowledge, attitudes and beliefs about herbal medicine as well as the patient/doctor relationship in this regard.

Method

A cross-sectional survey was conducted in several hospitals and medical centres in Makkah, KSA, between January and March 2019. Around 289 type II diabetic patients and 105 doctors were interviewed.

Results

We found that 68% of the participants were frequent consumers of herbal remedies, especially cinnamon, ginger and fenugreek. Patients’ knowledge of herbal usage was mainly gleaned from family and friends as well as social media, and we found that many (71.4%) did not bother to consult or inform their doctors about their choice to self-medicate with herbs. Patients had no concerns regarding the efficacy and safety of herbal usage use in diabetes, as around half of the participants believe that herbal medicine is effective (54%) and safe (46%) for treating symptoms of diabetes. Two-thirds of the doctors (66%) routinely ask patients whether they use herbs for their condition. Although 25% of the doctors took a positive view of herbal medicine in relation to diabetes, others expressed concerns with the rise in herb use and want to see more attention paid to safety aspects.

Conclusion

The study concludes that herbal remedies are commonly used by diabetic patients and that a gap exists in the relationship between patients and doctors concerning the disclosure of herbal remedy use and views on its safety.

Diagnoses associated with dietary supplement use in a national dataset

OBJECTIVES

The purpose of this study was to determine if participant diagnosis, as determined by a health care provider, is associated with dietary supplement (DS) use.

DESIGN/SETTING

Surveys from 1255 study participants aged 34-84, part of the Midlife in the US Study (MIDUS 2 Survey) Biomarker Project, were reviewed. Participant data included pharmaceutical use (prescription and over-the-counter medications (OTC)), clinical symptoms and diagnosis, and laboratory results. Associations were calculated between the above participant characteristics and DS use.

MAIN OUTCOME MEASURES

Frequency of DS use for physician-reported diagnoses.

RESULTS

Overall prevalence of DS use was 32.4%. Participants taking DS were more often female (p = .048), white (p < 0.001), and older (mean age 57 years, p < 0.001). Participants taking DS reported taking more OTC (p < .001) and prescription medications (p = .024), and had an increased number of chronic conditions (p = .004). Participants reporting physician-diagnosed diabetes were significantly less likely to be taking DS (p = .0066), while participants with eye disease (p = .001), high cholesterol (p = 0.041), cancer (p = 0.042), and arthritis (p = 0.044) were more likely to be taking DS than those without those conditions. No difference in DS use was found between patients with and without other identified medical conditions. After adjusting for age, race/ethnicity, and gender, only diabetes remained a significant predictor of decreased DS use (OR 0.588, CI 0.388-0.873, p = .01).

CONCLUSIONS

Some physician-reported participant diagnoses were associated, positively or negatively, with DS use.
