Effectiveness of a Disease Management Program (DMP) in controlling the progression of Chronic Kidney Disease among hypertensives and diabetics

Background

The occurrence rate of stage 5 chronic kidney disease (CKD) will be 151 per million population in India in the coming years. Comorbidities like diabetes mellitus and hypertension are the usual triggers of CKD. Hence this study aimed to control the progression of CKD and to note the effectiveness of a structured education program that would help in the prevention of complications related to diabetes and hypertension.

Methods

This quasi-experimental study was conducted among 88 participants who had hypertension, diabetes mellitus, or both for five or more years. The study objective was to find the effect of a Disease Management Program on delaying progression of CKD in patients with hypertension or diabetes mellitus.The baseline data were obtained from demographic proforma, and the clinical data collected were the blood pressure, serum creatinine, and random blood sugar (RBS) of the participants. The management of hypertension and diabetes mellitus was taught to them. In the fourth and the eighth month, blood pressure and blood sugar were reassessed. At one-year blood pressure, blood sugar, and serum creatinine were tested. Baseline and one-year follow-up blood pressure, blood sugar, and estimated Glomerular Filtration Rate were compared. Descriptive statistics and "Wilcoxon signed-rank test" were used to analyze the data.

Results

In one year, the mean systolic blood pressure reduced by six mm of Hg and mean blood sugar by 24 mg/dl. The prevalence of CKD stage three and above (< 60 ml/min/m2) was nine (10.22%). The median decline in eGFR was 5 ml/min/m2 (Z= 5.925, P< 0.001).

Conclusion

The Disease Management Program led to improvements in blood pressure and diabetes control and median progression of CKD was estimated at five ml/min/m2/year.

Quality of life in patients with alcohol use disorders admitted to de-addiction centers using WHOQOL-BREF scale-A cross-sectional study

BACKGROUND

Alcohol use disorders (AUDs) adversely affect a person's general health and the lives of their family and friends. These disorders are also the most undertreated mental illness with severe implications for public health. Hence, the present study aimed to employ the WHOQOL-BREF to assess the quality of life (QoL) of AUDs patients seeking treatment at de-addiction centers and identify the demographic variables associated with the QoL dimension scores.

MATERIALS AND METHODS

A cross-sectional study was conducted among alcohol dependents taking treatment in de-addiction centers in Dakshina Kannada District, Karnataka. The WHOQOL-BREF questionnaire was administered to 124 subjects. Multiple regression analysis was carried out to identify the demographic variables associated with the QoL dimension scores.

RESULTS

The domain mean scores were between 50 and 60 on the 0 to 100 scale. Age, social class, residential area, marital status, and years of drinking were the demographic variables found to be significantly associated with the dimension scores.

CONCLUSIONS

Physicians should monitor the effect of alcoholism on QoL, and a multidisciplinary treatment plan with elements from the medical, social, and psychiatric fields should be used. The demographic variables should be considered while managing patients with AUDs.

Academic stress and associated sociodemographic variables: A study of pre-university students in Karnataka, India

BACKGROUND

Academic stress is a predominant phenomenon among grade 11 and 12 students. The performance in Grade 12 is important for entry to higher education programs in India. The purpose of the study was to assess the magnitude of the perceived academic stress and identify the main stressors and the sociodemographic variables associated with the perceived academic stress among adolescents enrolled in the science stream in coastal Karnataka.

MATERIALS AND METHODS

Upon Institutional Ethical Committee approval, a cross-sectional survey was carried out among pre-university students (science stream) of coastal Karnataka during February-April 2021. The study used Manipal Inventory of Academic Stress (MIAS) scale to collect data on perceived academic stress from 1859 students (response rate 68.3%). Stratified cluster sampling method was used to collect data from the study participants. IBM Statistical Package for the Social Sciences (SPSS) 26.0 was used to analyze the data. Descriptive statistics, unpaired t-test, one-way analysis of variance (ANOVA), and multiple linear regression analyses were used to study the association between academic stress and various demographic variables.

RESULTS

The study revealed that 28% of the Grade 11 students and 26% of the Grade 12 students experienced high or extreme stress. The significant stressors were lack of time for revision, queries from neighbors or relatives, and parental expectations on academic performance. Gender, residence, and the medium of instruction until Grade 10 were associated with academic stress.

CONCLUSION

Measures at the institutional and national levels are necessary to reduce the academic stress in higher secondary education. The integrated curriculum proposed in the National Educational Policy 2020 addresses a few stressors identified in this study.

Knowledge and Awareness regarding Dental Management of Hemophilic Patients among Students of a Malaysian University: A Cross-Sectional Study

Background:

Improper management of bleeding disorders in the dental setting can lead to complications that can endanger the lives of such patients.

Objective:

This study aimed to assess the knowledge and awareness of dental management of hemophilia among undergraduate students of a Malaysian university.

Methodology:

A cross-sectional survey was conducted in the year 2018-2019 to collect the data. A 23-item questionnaire developed and validated by the authors was used to collect data on the knowledge and awareness regarding dental management of hemophilia patients. A total of 216 dental students participated in this research. Unpaired t-test and one-way ANOVA were used to compare the knowledge score between gender and academic year.

Results:

Only 21% of the participants were confident in treating a hemophilia patient. About 97% of the participants believed that the dental curriculum must be modified to emphasize the dental management of bleeding disorders. The overall mean of the knowledge score was 47.38% and awareness was 73.7% regarding the management of patients with hemophilia.

Conclusion:

The study revealed significant scope for improvement in the dental students' knowledge, which can be achieved by modifying the dental curriculum suitably to provide more emphasis on the management of bleeding disorders.

Knowledge, Attitude, and Perception Among Endodontists Toward Regenerative Endodontics: A Cross-sectional Survey of Four Indian Universities

Background:

Regenerative endodontics is a rapidly developing field in dentistry. However, the regenerative endodontic procedures are not familiar to many clinicians in India.

Aim:

This survey aimed at assessing the level of knowledge, attitude, and perception (KAP) among endodontists toward regenerative endodontics.

Materials and Methods:

A cross-sectional survey was conducted in the year 2019 to collect data. A questionnaire to collect data on KAP toward regenerative endodontics was administered to 49 faculty and 69 postgraduate students of endodontics from four universities. The Chi-Square test and logistic regression were applied to study the association between KAP and demographic variables. Spearman's rho was computed to study the correlation between KAP scale scores of the participants. The data were analyzed by using Statistical Package for the Social Sciences software program (SPSS), version 15.0 (South Asia, Bangalore).

Results:

The survey yielded an overall response rate of 81%. Less than 50% of the participants had sound knowledge, 65% had a positive attitude, and only 21% had a positive perception about Regenerative Endodontic Procedures (REPs). Most of the participants (86.5%) were of the opinion that regenerative therapies should be a part of dentistry. Majority of the participants (89.6%) were inclined to receive training in REPs. About 80% of the participants felt that the higher cost of treatment is a significant hurdle for patients to accept REPs. Less than half the participants (41.7%) were using REPs in their clinical practice, such as the use of membranes, scaffolds, and revascularization.

Conclusion:

Endodontists have a positive attitude toward the use of regenerative therapies. However, there is a deficiency of training in REPs in dental colleges.

Age Related Prevalence of Mild Cognitive Impairment in Type 2 Diabetes Mellitus Patients in the Indian Population and Association of Serum Lipids With Cognitive Dysfunction

The magnitude of type 2 diabetes mellitus (T2DM) is ever-increasing in India, and at present, ~77 million people live with diabetes. Studies have established that T2DM increases the risk of neurodegenerative disorders. This study aimed to determine the age-related prevalence of mild cognitive impairment (MCI) in T2DM patients in the Indian population and to identify link between cognitive dysfunction in T2DM patients and serum lipid composition through untargeted and targeted lipidomic studies. Using a cross-sectional study, we evaluated 1278 T2DM patients with Montreal cognitive assessment test (MoCA) and digit symbol substitution test (DSST) for cognitive functions. As per MoCA, the prevalences of MCI in T2DM patients in age groups below 40, 41-50, 51-60, 61-70, 71-80 and 81-90 years were 13.7, 20.5, 33.5, 43.7, 57.1 and 75% with DSST scores of 45.8, 41.7, 34.4, 30.5, 24.2 and 18.8% respectively. Binomial logistic regression analysis revealed serum HbA1c ≥ 7.51, duration of T2DM over 20 years, age above 41 years, and females were independent contributors for cognitive dysfunction in T2DM patients. Preliminary studies with untargeted lipidomics of the serum from 20 T2DM patients, including MCI and normal cognition (NC) group, identified a total of 646 lipids. Among the identified lipids, 33 lipids were significantly different between MCI and NC group, which comprised of triglycerides (TGs, 14), sphingolipids (SL, 11), and phosphatidylcholines (PC, 5). Importantly, 10 TGs and 3 PCs containing long-chain polyunsaturated fatty acids (PUFA) were lower, while 8 sphingolipids were increased in the MCI group. Since brain-derived sphingolipids are known to get enriched in the serum, we further quantified sphingolipids from the same 20 serum samples through targeted lipidomic analysis, which identified a total of 173 lipids. Quantitation revealed elevation of 3 species of ceramides, namely Cer (d18:1_24:1), Hex1Cer (d16:0_22:6), and Hex2Cer (d28:1) in the MCI group compared to the NC group of T2DM patients. Overall, this study demonstrated an age-related prevalence of MCI in T2DM patients and highlighted reduced levels of several species of PUFA containing TGs and PCs and increased levels of specific ceramides in T2DM patients exhibiting MCI. Large-scale lipidomic studies in future could help understand the cognitive dysfunction domain in T2DM patients, while studies with preclinical models are required to understand the functional significance of the identified lipids.

A Comparative Study of Surface Hardness between Two Bioceramic Materials in an Experimental Apexification Model under Wet and Dry Conditions

Background:

The placement of a wet cotton pellet against Mineral Trioxide Aggregate (MTA) is often recommended to ensure the completion of its setting reaction.

Objective:

This study aimed to evaluate the setting behaviour of MTA Angelus and NeoMTA by comparing their hardness after placing them in dry and moist conditions.

Methodology:

A simulated open apex was created on 40 polyvinyl tubes. The apical 4 mm of the tubes was filled with the two materials, NeoMTA Plus (Avalon Biomed Inc. Bradenton, FL, USA) and MTA Angelus (Angelus, Londrina, PR, Brazil) (n=20 per group). Both groups were subdivided into two subgroups based on the dry and wet conditions (n=10 per group). A wet cotton pellet was placed above the two materials in the wet group, and the coronal segment was sealed using Type II Glass ionomer cement (GC corporation Tokyo, Japan). Gutta-percha was placed against the test materials in the dry group with the coronal segment sealed with amalgam. Samples were placed in an oasis soaked in phosphate-buffered saline for seven days in 100% humidity and at 37°C. Microhardness was measured independently at 4 and 2 mm from the apex. Hardness was compared between materials and conditions, applying analysis of variance (a = .05).

Results:

The presence of dry or wet conditions had no significant effect on material hardness. MTA Angelus showed significantly higher hardness values compared with NeoMTA Plus.

Conclusion:

The moisture of the periapical environment can compensate for the absence of a wet cotton pellet and is adequate for the setting of the materials.

Dietary self-management practices among persons with T2DM: An exploratory qualitative study from western-coast of India

BACKGROUND

Diabetes is a significant public health challenge for India. Self-management, including dietary management, physical activity, stress management, and adherence to medication, is critical in glycaemic control. Though data concerning self-management, in general, are available among persons with Type 2 Diabetes Mellitus (T2DM), exclusive research on dietary self-management was limited.

AIMS

A qualitative study to explore the knowledge, current dietary practices, and the barriers and enablers for dietary self-care management in persons with T2DM.

METHODS

In this qualitative study, in-depth interviews were conducted among 35 participants with T2DM who scored minimally and optimally in the Diabetes Self-Management Questionnaire (DSMQ). Interviews were conducted using a validated interview guide. In-depth interviews were audio-recorded, transcribed to verbatim and thematically analysed.

RESULTS

The study included 20 males and 15 females. The three major themes derived in the study. Firstly, "Knowledge, Interpretation and Information" the majority of the participants have understood the influence of diet on control of blood glucose level includes food choices and quantum of food. Secondly, "Current Dietary Practices-Preferences, Availability of food and Convenience influence dietary practices': All participants had their own belief on the side effects and benefits of certain food items. Most of the participants followed a three-meal pattern: breakfast, lunch and dinner. Finally, Barriers and Enablers in dietary self-management practice. Knowledge, physical and emotional factors, behaviour, planning were the intrinsic factors. Elements of the research, social support, season and climate, food environment were the extrinsic factors and communication, and financial management was the intermediate influences observed.

CONCLUSION

The themes generated by this research provide insight into self-management and patient expectations in dietary matters. It would be desirable for physicians and health care providers to be aware of these practices when advising people with T2DM on dietary self - management.

Fracture Resistance of Endodontically Treated Maxillary Premolars with a Longer Single Post and Shorter Double Posts of Different Sizes: An In Vitro Study

Aim:

The aim of this study was to determine if there is any difference in fracture resistance between different post sizes and lengths when more than one post is involved.

Materials and Methods:

Thirty extracted maxillary first premolars were endodontically treated and divided into three groups: In Group 1 (control group), no post space preparation was conducted and access cavities were restored with composite; in Group 2 (single post), post space preparation of 10 mm was carried out only in one of the canals; and in Group 3 (double post), post space preparation of 5 mm was conducted in both the canals. Appropriately sized glass fiber posts were cemented in Groups 2 and 3 followed by core buildup. The fracture resistance of the specimen was measured using a universal testing machine and the data analyzed. The mean fracture resistance values of the three groups were compared applying one-way analysis of variance (ANOVA) followed by post hoc Tukey’s test. The data were analyzed using Statistical Package for the Social Sciences software program, version 15.0. South Asia, Bangalore.

Results:

The control group had a significantly lower fracture resistance value as compared to Groups 2 and 3. No statistically significant difference was observed in the fracture resistance between Groups 2 and 3.

Conclusions:

No significant difference was observed between the fracture resistance of endodontically treated maxillary first premolars restored with size 3 single post of longer length and size 1 double posts of shorter lengths.

Caregiver Burden among Caregivers of Mentally Ill Individuals and Their Coping Mechanisms

Background:

During a given year, almost 30% of the people around the world are affected by mentally ill health. In India, it accounts for about 20%. Caregivers face a lot of strain, ill health, and disrupted family life, with literature suggesting an increasing concern about their ability to cope up. The needs of caregivers of the mentally ill are given low priority in the current health-care setting in India.

Aim:

The aim of the study was to assess the burden of caregivers of mentally ill individuals and their coping mechanisms.

Methods:

A cross-sectional study was employed with a quantitative approach. A convenient sample of 320 caregivers was taken from two private tertiary care centers and one public secondary care center in Udupi taluk. This study was conducted using the Burden Assessment Schedule (BAS) and Brief Cope Scale (BCS). Statistical analysis was done on categorical variables, and they were expressed as frequencies and percentages. Continuous variables were measured using mean and standard deviation. Univariate and multivariate analysis using binomial logistic regression was done. SPSS version 15 was used to analyze the data.

Results:

According to BAS, severe burden accounted for 40.9% and moderate for 59.1%. The highest amount of burden was seen in the areas of physical and mental health, spouse related, and in areas of external support. The BCS showed that the most frequently used coping styles were practicing religion, active coping, and planning.

Conclusion:

This study concluded that caregivers of the mentally ill individuals do undergo a lot of burden. Hence, there is a need to develop strategies that can help them such as providing them with a support structure as well as counseling services.

Kinetics and kinematics of diabetic foot in type 2 diabetes mellitus with and without peripheral neuropathy: a systematic review and meta-analysis

Background

Diabetes mellitus patients are at increased risk of developing diabetic foot with peripheral neuropathy, vascular and musculoskeletal complications. Therefore they are prone to develop frequent and often foot problems with a relative high risk of infection, gangrene and amputation. In addition, altered plantar pressure distribution is an important etiopathogenic risk factor for the development of foot ulcers. Thus the review on study of foot kinematic and kinetic in type 2 diabetes mellitus to understand the biomechanical changes is important.

Methodology

Scientific articles were obtained using electronic databases including Science Direct, CINAHL, Springer Link, Medline, Web of Science, and Pubmed. The selection was completed after reading the full texts. Studies using experimental design with focus on biomechanics of diabetic foot were selected.

Results

The meta-analysis report on gait velocity (neuropathy = 128 and non-diabetes = 131) showed that there was a significantly lower gait velocity in neuropathy participants compared to non-diabetes age matched participants at a high effect level (−0.09, 95 % CI −0.13 to 0.05; p < 0.0001). Regarding knee joint flexion range there was a significant difference between neuropathy and non-diabetes group (4.75, 95 % CI, −7.53 to 1.97, p = 0.0008).

Conclusions

The systematic review with meta-analysis reported significant difference in kinematic and kinetic variables among diabetic with neuropathy, diabetic without neuropathy and non-diabetes individuals. The review also found that the sample size in some studies were not statistically significant to perform the meta-analysis and report a strong conclusion. Therefore a study with higher sample size should be done.

Cross-cultural adaptation, validation and reliability of the South Indian (Kannada) version of the Kidney Disease and Quality of Life (KDQOL-36) instrument

Health-related quality of life is an essential aspect concerned with the treatment outcomes. The main objective of the study is to evaluate the validity and reliability of the South Indian (Kannada) version of the Kidney Disease and Quality of Life-36 (KDQOL-36) instrument for hemodialysis (HD) patients. The KDQOL-36 instrument was validated by the committee of experts consisting of healthcare providers such as nephrologists (three), senior HD staff nurse (one) and clinical pharmacist (one). The measurement properties such as variability, reliability and validity were determined by administering the questionnaire to 82 patients on HD who were randomly selected from the HD units of three hospitals. The test and retest methods were used for reliability. Test-re-test reliability was assessed with a subsample of 45 patients by two administrations of the KDQOL-36 seven days apart. Data were collected through a face-to-face interview. It was evaluated computing intraclass correlation coefficients (ICC) and internal consistency estimated by computing Cronbach's-alfa. Reliability of each Kannada version of the KDQOL-36 sub-scale (symptoms/problems, burden of kidney disease, effects of kidney disease, physical component score [PCS] and mental component score [MCS] was good (Cronbach's-alfa >0.7, ranging from 0.72 to 0.77). The ICC ranged from 0.83 to 0.99 and the 95% confidence interval was 0.76-0.99 for test-retest of the KDQOL-36. The reliability measured with Cronbach's alfa, which was more than 0.72 and ICC ranged from 0.83 to 0.99, indicating that the Kannada version of the KDQOL-36 is reliable and valid for evaluating the health-related quality of life in Kannada-speaking HD patients.

Intrinsic foot muscle and plantar tissue changes in type 2 diabetes mellitus

BACKGROUND

Diabetes mellitus is a metabolic disorder with involvement of the neurovascular and muscular system. Peripheral neuropathy (PN) is thought to be the principal cause of foot complications in type 2 diabetes mellitus (T2DM). However, foot evaluation using ultrasonography early in the course of diabetes has not gained due importance. The aim of the present study was to evaluate the thickness of intrinsic foot muscles, plantar skin, plantar fascia, and plantar fat pad in T2DM subjects with and without PN using musculoskeletal ultrasonography.

METHODS

This study was conducted in 30 T2DM subjects with and without PN and 30 age-matched non-diabetes mellitus (NDM) subjects. After detailed clinical evaluation, high-frequency musculoskeletal ultrasonography was used to measure the thickness of the intrinsic foot muscles and plantar tissue thickness under the metatarsals. Data were analyzed using independent t-tests to compare T2DM groups with NDM subjects, and one-way ANOVA followed by Tukey's honestly significant difference test for between- and within-group analyses.

RESULTS

There was a significant reduction in the thickness of the intrinsic foot muscles and plantar tissue in T2DM compared with NDM subjects (P < 0.05). However, there were differences in intrinsic foot muscle and plantar tissue thickness between T2DM subjects with and without PN.

CONCLUSION

There was a substantial decrease in intrinsic foot muscle and plantar tissue thickness in T2DM compared with NDM subjects, indicating that structural changes appear in the foot before PN develops. The techniques used in this study cannot exclude the possibility that neuropathic changes that are clinically undetectable may develop in parallel with changes in plantar tissues.

Some basic aspects of statistical methods and sample size determination in health science research

A health science researcher may sometimes wonder “why statistical methods are so important in research?” Simple answer is that, statistical methods are used throughout a study that includes planning, designing, collecting data, analyzing and drawing meaningful interpretation and report the findings. Hence, it is important that a researcher knows the concepts of at least basic statistical methods used at various stages of a research study. This helps the researcher in the conduct of an appropriately well-designed study leading to valid and reliable results that can be generalized to the population. A well-designed study possesses fewer biases, which intern gives precise, valid and reliable results. There are many statistical methods and tests that are used at various stages of a research. In this communication, we discuss the overall importance of statistical considerations in medical research with the main emphasis on estimating minimum sample size for different study objectives.

Effect of limited access dressing on hydroxyproline and enzymatic antioxidant status in nonhealing chronic ulcers

Background:

Healing ability of nonhealing chronic ulcers can be assessed by estimating hydroxyproline, total protein and enzymatic antioxidants such as glutathione peroxidase (GPx), glutathione S-transferase (GST) in the granulation tissue.

Materials and Method:

A total of 34 patients were analysed from two groups: Limited access dressing (LAD) group (n = 17) and conventional dressing group (n = 17).

Results:

Patients treated with LAD that exerts combination of intermittent negative pressure and moist wound-healing had shown a significant increase in the hydroxyproline (P = 0.026), total protein (P = 0.004), GPx level (P = 0.030) and GST level (P = 0.045).

Conclusion:

Patients treated with LAD indicated significantly better anabolic effect on wound-healing compared to that of patients treated with conventional dressing.

Learning approaches and learning difficulties: a comparison of Indian and Nepali dental science students

This study explored the difference in learning approaches and difficulties of Nepali and Indian undergraduate students of dental science. A locally developed inventory was used to measure learning approach and learning difficulties. Data collected from 166 Indians and 69 Nepalis were compared. The scores on various scales of the inventory indicate that Nepalis are more fearful and less confident regarding examination and course completion and have significantly less positive perception about academic capability. Indian students scored significantly higher on motivation, interest, and deep processing. The language problem was significantly greater for Nepali students. Higher percentages of Nepalis experienced various academic and nonacademic problems. The study highlights the need to consider difference in learning approach among the students of health science courses that admit students from different academic, nonacademic, and cultural backgrounds.
