Fall risk factors among poly-medicated older Lebanese patients in primary care settings: a secondary cross-sectional analysis of the "MGPIDP-L project".

BACKGROUND: Falling is a major concern for the health of older adults and significantly affects their quality of life. Identifying the various risk factors and the differences between older patients can be challenging. The objective of this study was to identify the risk factors for falls among polymedicated community-dwelling older Lebanese patients following a medication review. METHODS: In this analytical cross-sectional study, we examined the risk factors for falls in 850 patients aged ≥ 65 years who were taking ≥ 5 medications daily. The study involved conducting a medication review over the course of a year in primary care settings and using multivariate logistic regression analysis to analyze the data. RESULTS: Our results showed that 106 (19.5%) of the 850 included patients had fallen at least once in the three months prior to the medication review. Loss of appetite and functional dependence were identified as the most significant predictors of falls ORa = 3.020, CI [2.074-4.397] and ORa = 2.877, CI [1.787-4.632], respectively. Other risk factors for falls included drowsiness ORa = 2.172, CI [1.499-3.145], and the use of beta-blockers ORa = 1.943, CI [1.339-2.820]. CONCLUSION: Our study highlights the importance of addressing multiple risk factors for falls among Lebanese older adults and emphasizes the need for customized interventions and ongoing monitoring to prevent falls and improve health outcomes. This study sheds light on a critical issue in the Lebanese older population and provides valuable insight into the complex nature of falls among poly-medicated Lebanese community-dwelling older adults.

Visit-to-visit blood pressure variability is associated with intrinsic capacity decline: Results from the MAPT Study.

BACKGROUND: The effectiveness of the body physiological regulatory mechanisms declines in late life, and increased Blood Pressure Variability (BPV) may represent an alteration in cardiovascular homeostatic patterns. Intrinsic Capacity (IC) has been proposed by the World Health Organization as a marker of healthy aging, based on individual's functional abilities and intended at preserving successful aging. We aimed to investigate the association of visit-to-visit BPV with IC decline in a population of community-dwelling older adults. METHODS: The study population consisted of 1407 community-dwelling participants aged ≥70 years from the MAPT study evaluated during the 5-year follow-up. Systolic BPV (SBPV) and diastolic BPV (DBPV) were determined through six indicators. Cognition, psychology, locomotion and vitality constituted the four IC domains assessed. Total IC Z-score resulted from the sum of the four domains Z-scores divided by 4. The incidence of domain impairment over time was also assessed. RESULTS: Higher SBPV was significantly associated with poorer IC Z-scores in all linear mixed models [1-SD increase of CV%: ß(SE)=-0.010(0.001), p < 0.01]. Similar results were observed for DBPV [1-SD increase of CV%: ß(SE)=-0.003(0.001), p = 0.02]. Incident IC impairment was significantly higher in participants with greater SBPV, [HR=1.16 (95 % CI, 1.01-1.33), p = 0.03], while greater DBPV did not show a higher risk of incident IC impairment. CONCLUSIONS: Greater BPV is associated with IC decline over time. Our findings support BP instability as a presumable index of altered cardiovascular homeostatic mechanism, suggesting that BPV might be a clinical marker of aging and addressable risk factor for promoting healthy aging.

Cerebrovascular and cardiovascular autonomic regulation in sickle cell patients with white matter lesions.

BACKGROUND AND PURPOSE: White matter lesions (WMLs) are frequent in sickle cell disease (SCD), with a prevalence described to be as high as 53% by age 30. Cerebrovascular regulation and cardiovascular autonomic regulation, more specifically the sympatho-vagal balance, can be altered in SCD. In this study the association between WMLs, cerebrovascular regulation and sympatho-vagal balance was assessed in SCD patients. METHODS AND RESULTS: Sickle cell disease patients with no history of stroke were prospectively evaluated for cerebrovascular reactivity using the breath-holding test (BHT), the sympatho-vagal balance (ratio low frequency/high frequency [HF]) using heart rate variability parameters and cerebral autoregulation in the time domain using correlation index Mx, and arterial cerebral compliance based on continuous assessment of cerebral blood flow velocities using transcranial Doppler ultrasound and arterial blood pressure with photo-plethysmography. WMLs were assessed with magnetic resonance imaging using Fazekas score grading and the presence of lacunes. Forty-one patients (F/M 25/16) were included. Median age was 37.5 years (19-65). Twenty-nine (70.7%) patients had SS genotype. Eleven patients had WMLs (26.8%). Patients with WMLs were significantly older (p < 0.001), had a lower HF (p < 0.005) and an impaired cerebral arterial compliance (p < 0.014). The receiver operating curve for the regression model including age and HF showed a higher area under the curve compared to age alone (0.946 vs. 0.876). BHT and Mx did not significantly differ between the two groups. CONCLUSIONS: Lower parasympathetic activity and impaired cerebral arterial compliance were associated with WMLs in adults with SCD. This could potentially yield to a better understanding of pathophysiological parameters leading to premature cerebrovascular ageing in SCD.

The MGPIDP-L project: Potentially inappropriate drug prescribing and its associated factors.

OBJECTIVE: The aim of this study was to identify the prevalence of potentially inappropriate drug prescribing1 (PIDP) using a combination of explicit and implicit criteria in a sample of Lebanese older adults taking 5 or more chronic medications per day in ambulatory care settings and to identify which factors were associated with PIDP. The explicit criteria included five different lists: Beers, Laroche, European Union (EU(7)-PIM list), STOPP/ START, STOPP Frail, and Alert and Mastering of Iatrogenesis issued by the French High Authority of Health. We also performed a sensitivity analysis to compare the potentially inappropriate medications according to each criterion. METHODS: Data were collected from each patient via a face-to-face interview. Logistic regressions were conducted to evaluate both objectives. RESULTS: Many factors were positively associated with PIDP. The risk of PIDP was positively associated with age (OR =4.692, 95% CI [1.889-11.655]). Treatment for insomnia doubled the odds of PIDP (P<0.05). Participants who picked their medications from the pharmacy and had excess stock of drugs were at higher risk of having PIDP by 2.042 (95% CI [1.199-3.478]) and 2.965(95% CI [1.133-7.762]) respectively. However, patients with a perception of being heavily medicated and patients with a missed dose in the last two weeks had lower odds of PIDP. CONCLUSION: Our study showed a high prevalence of PIDP in Lebanon, which is associated with various correlates. Selecting the appropriate tools to assess PIDP and providing patient education regarding the risks associated with potentially inappropriate medications are issues to be addressed among older adults.

Biomarkers of mitochondrial dysfunction and inflammaging in older adults and blood pressure variability.

Most physiopathological mechanisms underlying blood pressure variability (BPV) are implicated in aging. Vascular aging is associated with chronic low-grade inflammation occurring in late life, known as "inflammaging" and the hallmark "mitochondrial dysfunction" due to age-related stress. We aimed to determine whether plasma levels of the pleiotropic stress-related mitokine growth/differentiation factor 15 (GDF-15) and two inflammatory biomarkers, interleukin 6 (IL-6) and tumor necrosis factor receptor 1 (TNFR-1), are associated with visit-to-visit BPV in a population of community-dwelling older adults. The study population consisted of 1096 community-dwelling participants [median age 75 (72-78) years; 699 females, 63.7%] aged ≥ 70 years from the MAPT study. Plasma blood sample was collected 12 months after enrolment and BP was assessed up to seven times over a 4-year period. Systolic (SBPV) and diastolic BPV (DBPV) were determined through several indicators taking into account BP change over time, the order of measurements and formulas independent of mean BP levels. Higher values of GDF-15 were significantly associated with increased SBPV (all indicators) after adjustment for relevant covariates [adjusted 1-SD increase in GDF-15: ß (SE) = 0.07 (0.04), p < 0.044, for coefficient of variation%]. GDF-15 levels were not associated with DBPV. No significant associations were found between IL-6 and BPV, whereas TNFR1 was only partially related to DBPV. Unlike inflammation biomarkers, higher GDF-15 levels were associated with greater SBPV. Our findings support the age-related process of mitochondrial dysfunction underlying BP instability, suggesting that BPV might be a potential marker of aging.

Development of a decision tree for the pharmacy-led consultation of elderly patients with haematological malignancies.

INTRODUCTION: Elderly patients with haematological malignancies are a population at risk of iatrogenic for whom these activities could optimize therapeutic management. However, the limitation of human resources requires optimization of the process in order to improve the efficiency of pharmaceutical activities. The objective was to build a decision tree to optimize the pharmaceutical consultation in these population within a multidisciplinary team in haematology. METHOD: Pharmaceutical consultations were proposed to elderly subjects with haematological malignancies followed up in a haematology day hospitalization at the University Hospital of Limoges. Risk factors for prescribing risky drugs in this population were determined by logistic regression models. A decision tree was constructed based on these results and by agreement between pharmacist, geriatrician and hematologist. RESULTS: Female gender (aOR[CI95%] = 1.71 [1.14-2.57]), polypharmacy (aOR[CI95%] = 1.89 [1.14-3.13]), hyper-polypharmacy (aOR[CI95%] = 5.73 [3.03-10.84]) and moderate cholinergic load (aOR[CI95%] = 2.15 [1.04-4.45]) were risk factors for the prescription of inappropriate medicine. Female gender (aOR[CI95%] = 1.55 [1.02-2.35]) and hyper-polypharmacy (aOR[CI95%] = 6.19 [1-1.28]) were risk factors for prescribing anticholinergic drugs or anticoagulants; in contrast, frailty status was a protective factor for prescribing anticholinergics (aOR[CI95%] = 0.51 [0.33-0.81]). Prioritization of pharmaceutical consultations is based on frailty status, prescription of a target drug and polypharmacy. DISCUSSION: Pharmaceutical consultations during the day hospitalization of elderly subjects with hematological diseases allow to propose therapeutic optimizations. The prioritization proposed in our study would increase the efficiency of pharmaceutical activities in order to improve quality and safety throughout the care pathway of these patients.

Dermatological adverse drug reactions of anticancer drugs: International data of pharmacovigilance: VigiBase®.

In the 2000s, newer generations of drugs appeared on the market called drugs of targeted therapy (TT) drugs. The introduction of TT in oncology has profoundly changed the prognosis of many cancers but also introduced a wide variety of adverse drugs reactions (ADR), including in particular dermatological adverse drug reactions (DADRs). We investigated the evolutions of the notifications of DADRs of anticancer drugs since 2000s in international pharmacovigilance data. For this purpose, we separated non-targeted therapy and targeted therapy. During the period from 01/01/2000 to 31/12/2017, 1,226,252 ICSRs (8.7%) were related to anticancer drugs, among them concerning anticancer drugs, 192,108 cases (15.6%) contained at least one MedDRA term for "skin and subcutaneous tissue disorders" system organ classes. The DADRs of anticancer drugs are in constant increase on the period 2000 to 2017, from 0.91% to 1.90% of the total ADR of Vigibase®. The number of DADRs drugs in the non-targeted therapies class remained stable during this period, while the DADRs of targeted therapy drugs increased and exceeded those of non-targeted therapy in recent years. Using a disproportionality analysis, we found that targeted therapy drugs are associated with a higher risk of reporting DADRs of the type: dermatitis acneiform, hair color changes, acne, and hyperkeratosis and skin toxicity. While, non-targeted therapy drugs are associated with a higher risk of reporting DADRs of the type: skin hyperpigmentation, nail discoloration, dermatitis exfoliative, Hyperhidrosis and alopecia. TT drugs are used more and more for cancer indications and even beyond. This problematic of DADR will become more and more common and should benefit from specialized support with the organization of a coordinated network of professionals.

[Potentially inappropriate medication: Adaptation of EU(7)PIM criteria to the French medical practice]. / Les médicaments potentiellement inappropriés : adaptation de la liste EU(7)PIM à la pratique médicale française.

OBJECTIVE: Improving the quality of prescribing in the elderly remains a permanent concern and a major opportunity to improve patient care. The objective of this article is to propose, from updated existing lists of potentially inappropriate medication (PIM), a list of PIM adapted to the French medical practice. METHOD: Combination of an explicit tool: the updated EU (7) PIM list published in 2015, adapted to the French medical practice (availability of drugs and validated indications), and an implicit tool: the recommendations of French National Health Authority (HAS) and more specifically the "alerte et maîtrise de la iatrogénie" (AMI) tools. RESULTS: From 289 PIM identified in the EU(7) PIM list, 183 drugs were included in our list according to our method. Three PIM were added to the list of "questionable" PIMs in accordance with the new French recommendations. A total of 90 PIMs were removed because of their indications or their non-commercialization in France. CONCLUSION: This work provides an adaptation of the EU(7)PIM to the French medical practice with the guidance of the HAS recommendations. This list is intended to be easy to use for the identification of PIMs by French physicians.

Platelet function defects and sertraline-induced bleeding: a case report.

A 71-year-old man is admitted for nose bleeds recurring for several days. His medical background shows in particular major depression for which he has been receiving sertraline for several years. The workup shows anemia, and no anomalies on head and neck CT angiography. However, further explorations suggest an acquired thrombopathy that could have contributed to the bleeding. During sertraline exposure, platelet functional exploration and platelet secretion were abnormal. Sertraline is often used as first-line treatment of depression. Pharmacological data and spontaneous notifications suggest increased potential risk with sertraline. It appears necessary to pay attention to bleeding with sertraline use.

The impact of chronic myeloid leukemia on employment: the French prospective study.

Patients with chronic myeloid leukemia treated with breakpoint cluster region-Abelson tyrosine kinase inhibitors are likely to survive in excess of 20 years after diagnosis. New challenges appear as we consider life after the disease, including professional challenges and the social reintegration of patients. The purpose of this study was to determine the impact of chronic myeloid leukemia on employment within 2 years after diagnosis. This prospective, observational study included patients diagnosed with chronic myeloid leukemia and treated with a tyrosine kinase inhibitor. Two populations were defined as patients who reported modifications in their professional activity during the study (Acti-Pro+) and patients who did not report a modification (Acti-Pro-). Cancer survivors received a self-assessment questionnaire. The primary endpoint was to determine the professional status of patients. One hundred patients completed the questionnaire. Sixty-six patients out of 100 reported professional activity within 2 years after their diagnosis. During the 2 years after the diagnosis, 65.2% (95% confidence interval (CI), 53.7-76.7) of patients faced modifications in their professional activity due to chronic myeloid leukemia or adverse effects of drug treatments (group Acti-Pro+); in contrast, 34.8% of patients did not report any impact on their occupational activity (group Acti-Pro-). Among modifications to work organization, a change in the number of working hours was the most represented. Other modifications comprised changes in status or work pace. A majority of chronic myeloid leukemia patients face professional consequences of their disease and treatments. Our findings suggest that adverse drug reactions are a major factor affecting the occurrence of work modifications in this context.
