Personality Traits, Clinical Characteristics, and Health-Related Quality of Life of Patients with Hypertension in a Primary Hospital in Ghana

Analysis of Spontaneously Reported Adverse Drug Events: Towards Developing Systems for Preventability

Background: Analysing data on adverse drug reactions (ADRs) in health facilities is an essential step to help develop effective strategies to reduce their incidence. The objective was to analyse spontaneous ADR reports sent to the Ghanaian Food and Drugs Authority (FDA) by two reporting health facilities over 5 years. Methods: Data from duplicate spontaneous ADR reports sent to the FDA (Ghana) from 2014 to 2018 were extracted. The relationship between independent variables such as age, sex, and source of drugs and ADR outcomes was assessed with either chi-square or a Cramer's V test for association where appropriate. Results: Type A reactions (65.2%) were the most prevalent of the ADRs, followed by Type B (34.1%), with the majority (80%) of patients affected recovering fully. The majority of Type A reactions (54.1%) occurred in the clinic, while the majority of Type B reactions (43.5%) occurred in the hospital. The skin and central nervous system (CNS) were the most affected (70.8%) organs. A higher incidence of CNS and skin-related ADRs was recorded in patients older than 30 (RR = 1.28 (1.07-1.53)). Also, females were more likely to experience a CNS-related ADR. The seriousness of the ADR was found to be significantly associated with the (1) type of prescriber, (2) whether the drug was prescribed, or (3) whether the drug regimen prescribed was appropriate. Even though, in 86% of cases, the offending drug was withdrawn within the first 5 days, it exceeded 20 days in about 6% of cases. The record of allergy status in a patient's folder and the source of the drug were significantly associated with the chance that the offending drug was withdrawn. However, recording ADRs did not influence whether the offending drug was stopped. Conclusion: Most of the ADRs experienced by patients could be avoided if the current systems are improved to prevent the rechallenge of offending drugs. Efforts to improve and update patient medication records and steps to ensure continuity of care are essential in preventing these adverse drug events.

Perseverative Cognition as a Mediator Between Personality Traits and Blood Pressure

Purpose

Several authors link hypertension with psychological dispositions such as stress, personality, and anxiety, some propose that stress is not enough to explain arterial hypertension and others propose the perseverative cognition model to explain. The aim of this study was to relate personality traits and blood pressure profile of a group of workers, examining the results of perseverative cognition as a possible mediating variable concerning blood pressure.

Patients and Methods

Cross-sectional design study, with a sample of 76 employees of a Colombian university. The NEO-FFI, RRS, and blood pressure measurement instruments were applied; data were reviewed through correlation and mediation analysis.

Results

We found evidence of association between neuroticism and perseverative cognition (rho=0.42 with brooding; rho =0.32 with reflection), but no evidence about mediation of perseverative cognition between personality and blood pressure.

Conclusion

It is necessary to keep researching the mechanisms related to the occurrence of hypertension.

Medicated-related burden and adherence in patients with co-morbid type 2 diabetes mellitus and hypertension

Background

Medication adherence is an integral component in the management of patients with co-morbid type 2 diabetes mellitus (T2DM) and hypertension. However due to their combined conditions, there is likelihood of polypharmacy and medication-related burden, which could negatively impact adherence to therapy. This study aimed to assess the perceived medication-related burden among patients with co-morbid T2DM and hypertension and to evaluate the association between the perceived burden and adherence to medication therapy.

Methods

A cross-sectional study was conducted among adult patients with co-morbid T2DM and hypertension attending a primary health facility. The living with medicines questionnaire and the medication adherence report scale were used to assess extent of medication-related burden and adherence respectively. Binary logistic regression model was used to estimate the adjusted odds and their corresponding 95% confidence interval for medication-related burden and adherence outcomes. All observed categorical variables were considered for the multivariable binary logistic regression model.

Results

The total number of participants was 329 with a median age of 57.5 ± 13.2 years. The median score for the overall burden was 99 (IQR: 93-113), and this significantly varied by sex (p = 0.012), monthly income (p = 0.025), monthly expenditure on medications (p = 0.012), frequency of daily dose of medications (p = 0.020) and family history of T2DM (p < 0.001). About 30.7% and 36.8% of participants reported moderate/high burden and medication adherence respectively. Uncontrolled diastolic blood pressure (AOR: 2.46, 95% CI: 1.20-5.05, p = 0.014), high glucose (AOR: 4.24, 95% CI: 2.13-8.46, p < 0.001) and no family history of T2DM (AOR: 2.14, 95% CI: 1.14-4.02, p = 0.026) were associated with moderate/high medication burden. Uncontrolled diastolic blood pressure (AOR: 0.48, 95% CI: 0.25-0.94, p = 0.031), at least 5 years since hypertension diagnosis (AOR: 0.55, 95% CI: 0.30-0.99, p = 0.045) and moderate/high medication-related burden (AOR: 0.33, 95% CI: 0.16-0.69, p = 0.003) were associated with lower odds of medication adherence.

Conclusion

These findings suggest that to improve the preventive and optimal care of patients with T2DM and hypertension, interventions that aim to reduce medication-related burden and morbidity are recommended. The study proposes that health stakeholders such as clinicians, pharmacists, and policy makers, develop multidisciplinary clinical and pharmaceutical care interventions to include provision of counselling to patients on adherence. In addition, developing policies and sensitization activities on deprescribing and fixed-dose drug combinations aimed at reducing medication-related burden, while promoting better adherence, blood pressure and blood glucose outcomes are recommended.

Psychological aspects in early adjustment after severe burn injury

Burn injury is one of the most serious traumatic events with possible psychological and psychosocial consequences. Health status perception is one of the main health outcomes. The severity of psychological symptoms does not always correlate with that of the burn injury, suggesting that early screening for psychological vulnerabilities may be beneficial. The aim of our study was to identify the personality, clinical, and sociodemographic characteristics related to patient´s subjective perception of health, depression, and anxiety, in a sample of 52 adult patients with severe burn injury shortly before discharge from specialty Burn clinic. Subjective health perception was predicted by depression (β = -.143, t(47) = -3.94, P < .001) and neuroticism (β = -.106, t(43) = -4.83, P < .001), and it correlated positively with extraversion (r = .2858, P = .0465) and conscientiousness (r = .3663, P = .0096). Depression was predicted by neuroticism (F(1,49) = 18.4; P < .001) and correlated with attachment avoidance (r = .29, P = .0383) and negatively with extraversion (r = -.32, P = .0220). Anxiety was related to attachment anxiety (F(1,49) = 4.25; P = .045), neuroticism (F(1,49) = 15.75; P < .001), and agreeableness (r = -.36, p = .0101). Unemployed patients experienced higher levels of depression and anxiety. This research suggests that personality traits and adult attachment may play an important role in the acute phase of the recovery from a severe burn injury. These findings can be relevant for early intervention and holistic rehabilitation.

Meta-Analysis of the Association Between the rs228570 Vitamin D Receptor Gene Polymorphism and Arterial Hypertension Risk

The association between FokI polymorphism in the vitamin D receptor (VDR) gene and susceptibility to arterial hypertension (HT) is controversial. Thus, we evaluated the relation between FokI and HT according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using MEDLINE® (Medical Literature Analysis and Retrieval System Online)/PubMed, Scopus, and Cochrane Library CENTRAL databases. Data from case-control studies, including the number of participants, age, 25-hydroxyvitamin D concentrations, systolic and diastolic blood pressure values, FokI allele, and genotype frequency were extracted by 2 independent authors and OR was calculated with the 95% CI to assess the strength of the association between the FokI variant and odds of HT. In general and subgroup analyses, we used allelic (f compared with F), common (ff compared with FF + Ff), risk (ff + Ff compared with FF), and additive (ff compared with FF) models. Six case-control studies including 3140 cases and 3882 controls were reviewed in the meta-analysis. Global assessment revealed a correlation between FokI and reduced odds of HT in the additive/homozygote model (ff compared with FF; OR: 0.65; 95% CI: 0.45-0.94) and common/recessive model (ff compared with FF + Ff; OR: 0.75; 95% CI: 0.57-0.99). In Asian subjects, there was a significant reduction in the odds of HT in additive (ff compared with FF; OR: 0.84; 95% CI: 0.73-0.98) and risk models (ff + Ff compared with FF; OR: 0.87, 95% CI: 0.78-0.97), in particular, for Indians (South). In Africans, the statistically significant association occurred in the additive and common models. Allele f in the FokI polymorphism of the VDR gene was associated with reduced odds of HT in the general population based on the risk model. Thus, nutritional genomics can help understand the influence of nutrition on metabolic homeostasis pathways and the clinical consequences of hypertension. This study shows the need for healthy, anti-inflammatory, and antioxidant compounds to prevent or treat chronic complications.
