Effect of Macronutrients or Micronutrients Supplementation on Nutritional Status, Physical Functional Capacity and Quality of Life in Patients with COPD: A Systematic Review and Meta-Analysis.

Given the importance that a correct and balanced nutrition has on patients with chronic obstructive pulmonary disease (COPD), supplementation of macro and micronutrients has been proposed, but the results of previous meta-analyses are contrasting. We performed an update of the latest evidence through a systematic review and meta-analysis of studies to assess the role of nutritional supplements in improving nutritional status, pulmonary function, physical performance, and quality of life of these patients.We included randomized controlled trials (RCTs) published between 01-01-2010 and 11-01-2023 evaluating the effectiveness of nutritional support in patients affected by stable COPD with an intervention of at least 2 weeks. Primary outcomes were changes in body mass index (BMI) and fat free mass index (FFMI). Secondary outcomes were exercise tolerance (6-min walking test, 6MWT), quality of life (St George's Respiratory Questionnaire, SGRQ) and respiratory function (FEV1). According with supplements type (macronutrients or micronutrients), we calculated the pooled adjusted mean difference (MD) and 95% confidence intervals (95%CIs) of the selected outcomes, using random-effects models in presence of high heterogeneity (I2>50%) or fixed-effects models otherwise. The risk of publication bias was evaluated with the trim and fill method.From 967 articles, 20 RCTs were included. Macronutrients supplementation improved BMI (MD 1.0 kg/m2, 95%CI 0.21-1.79), FFMI (MD 0.77 Kg/m2, 95%CI 0.48-1.06), 6MQT (MD 68.39 m, 95%CI 40.07-96.71), and SGRQ (MD -5.14, 95% CI -7.31-2.97), while it does not ameliorate respiratory function (MD 0.26% 95%CI -1.87-2.40). Micronutrients supplementation alone did not improve any of the considered outcomes.

Is Citicoline Effective in Preventing and Slowing Down Dementia?-A Systematic Review and a Meta-Analysis.

BACKGROUND: Cognitive impairment is a staggering personal and societal burden; accordingly, there is a strong interest in potential strategies for its prevention and treatment. Nutritional supplements have been extensively investigated, and citicoline seems to be a promising agent; its role in clinical practice, however, has not been established. We systematically reviewed studies on the effect of citicoline on cognitive performance. METHODS: We searched the PubMed and Cochrane Library databases for articles published between 2010 and 2022. Relevant information was extracted and presented following the PRISMA recommendations. Data were pooled using the inverse-variance method with random effects models. RESULTS: We selected seven studies including patients with mild cognitive impairment, Alzheimer's disease or post-stroke dementia. All the studies showed a positive effect of citicoline on cognitive functions. Six studies could be included in the meta-analysis. Overall, citicoline improved cognitive status, with pooled standardized mean differences ranging from 0.56 (95% CI: 0.37-0.75) to 1.57 (95% CI: 0.77-2.37) in different sensitivity analyses. The overall quality of the studies was poor. DISCUSSION: Available data indicate that citicoline has positive effects on cognitive function. The general quality of the studies, however, is poor with significant risk of bias in favor of the intervention. Other: PubMed and the Cochrane Library.

COVID-19 as a Paradigmatic Model of the Heterogeneous Disease Presentation in Older People: Data from the GeroCovid Observational Study.

COVID-19 may have a heterogeneous onset, especially in older age. However, whether and how COVID-19 signs and symptoms may present and aggregate together according to sociodemographic and health factors is unclear, as well as their prognostic value. This study included 981 COVID-19 inpatients who participated in the GeroCovid Observational study. Signs/symptoms at disease onset, sociodemographic, health, cognitive status, and mobility were systematically recorded. Clusters of signs/symptoms were identified through agglomerative hierarchical clustering. The associations of single signs/symptoms and symptom clusters with longer hospitalization (≥16 days) and in-hospital mortality were explored through logistic and Cox regressions. The signs/symptoms most reported in our sample (age 78.3 ± 9.39 years; 49.4% women) were fever (62.5%), cough (45.5%), and dyspnea (62.7%). Atypical symptoms were reported by up to one-third of patients, and delirium by 9.1%. Atypical symptoms were more frequent with advancing age and with lower pre-COVID-19 cognitive and mobility levels. Older men more likely reported respiratory symptoms than women. Dyspnea (hazard ratio [HR] = 1.47, 95% confidence interval [CI]: 1.02-2.12), tachypnea (HR = 1.53, 95% CI: 1.14-2.07), low oxygen saturation (HR = 1.95, 95% CI: 1.32-2.88) and delirium (HR = 1.60, 95% CI: 1.13-2.28) were associated with higher in-hospital mortality. Four symptom clusters were identified. Compared with the mild respiratory symptoms cluster, the severe clinical impairment cluster was associated with higher mortality (HR = 2.57, 95% CI: 1.58-4.18). The severe clinical impairment and aspecific symptoms clusters were associated with longer hospitalization (odds ratio [OR] = 2.38, 95% CI: 1.56-3.63, and OR = 1.75, 95% CI: 1.08-2.83, respectively). Multiple health aspects influence COVID-19 clinical presentation. A symptom clusters approach may help predict adverse health outcomes in older patients. In addition to respiratory symptoms, delirium is independently associated with mortality risk. ClinicalTrials.gov (NCT04379440).

Ultrasound Evaluation of Diaphragmatic Mobility and Contractility After Osteopathic Manipulative Techniques in Healthy Volunteers: A Prospective, Randomized, Double-Blinded Clinical Trial.

OBJECTIVE: The purpose of this study was to investigate the effect of a session of osteopathic manipulative techniques on diaphragmatic motion and thickness in healthy participants. METHODS: This was a prospective, randomized, double-blinded, case vs sham vs control clinical trial performed in an outpatient osteopathic clinic in Rome, Italy. Sixty-seven healthy participants, mean age 40.4 ± 14.5 years, received an ultrasound evaluation of diaphragmatic motion and thickness, followed by a systematic osteopathic evaluation. After randomization, the experimental group (n = 22) received osteopathic manipulation, whereas the sham (n = 22) and the control (n = 22) groups had a light touch approach and simple observation, respectively. After a 1-session intervention, new osteopathic and ultrasound assessments were repeated in all participants. RESULTS: A statistically significant increase in diaphragmatic mobility was observed in the experimental group after the osteopathic manipulation (Δ = 14.5 mm, P < .001; analysis of variance P < .001 vs both sham: Δ = -0.22 mm, and control: Δ = -2.09 mm groups). A strong linear relationship was observed between the diaphragmatic motion gradient, measured with ultrasonography, and the score assigned by the operator evaluating the change of diaphragm mobility after intervention. CONCLUSION: Osteopathic techniques used in this study improved the diaphragmatic motion (but not the muscle thickness) in healthy participants. Further studies are needed to confirm our findings and eventually identify the clinical conditions that may benefit from osteopathic manipulative treatment of the diaphragm.

Assessing Nephrological Competence among Geriatricians: A Proof of Concept Internet Survey.

Chronic kidney disease (CKD) is highly prevalent in the elderly and negatively impacts survival and health status. Thus, nephrological competence is mandatory for a skilled geriatrician. The present study aimed to assess nephrological competence in a sample of geriatricians recruited through a web survey. To this aim, a 12-items questionnaire was produced by an expert panel of nephrologists and geriatricians and was available online for members of the Italian Society of Gerontology and Geriatrics (SIGG). Two-hundred-eighty-seven geriatricians volunteered to fill in the questionnaire. The majority of them indirectly estimated the glomerular filtration rate (GFR) using mainly the Cockroft-Gault (C-G) formula. Selected nephrological exams, such as urinary Na and serum D-vitamin measurements, did not qualify as routine exams although the majority of geriatricians supplemented their patients with fat-soluble secosteroids. Ten percent of geriatricians asked for nephrological consultation only for stage 5 CKD patients and 30,9% only for stage 4 or 5. Erythropoietin supplementation was common practice for the majority of geriatricians, while only one third of them systematically used a procedure intended to prevent the contrast induced nephropathy (CIN). Finally, an alleged 50% adherence to the international guidelines for the management of CKD patients emerged from the questionnaire. Overall, results from this survey strongly recommend promoting nephrological education among geriatricians. Didactic standards for in training geriatricians need to be updated and the cooperation between geriatrics and nephrological societies promoted.

Dilution of a mepivacaine-adrenaline solution in isotonic sodium bicarbonate for reducing subcutaneous infiltration pain in ambulatory phlebectomy procedures: a randomized, double-blind, controlled trial.

BACKGROUND: Varicose veins are treated under local infiltration anesthesia. Literature shows that adding sodium bicarbonate reduces the pain associated with local infiltration anesthesia. Nonetheless, sodium bicarbonate is underused. OBJECTIVE: We sought to assess if the use of a solution of mepivacaine 2% plus adrenaline with sodium bicarbonate 1.4% results in less pain associated with local infiltration anesthesia preceding ambulatory phlebectomies, compared with standard preparation diluted with normal saline. METHODS: In all, 100 adult patients undergoing scheduled ambulatory phlebectomy were randomized to receive either a solution of mepivacaine chlorhydrate 2% plus adrenaline in sodium bicarbonate 1.4% or a similar solution diluted in normal saline 0.9%. RESULTS: Median pain scores associated with local infiltration anesthesia reported in the intervention and control groups were 2 (SD=1.6) and 5 (SD=2.0) (P<.0001), respectively. A general linear model with bootstrapped confidence intervals showed that using the alkalinized solution would lead to a reduction in pain rating of about 3 points. LIMITATIONS: Patients were not asked to distinguish the pain of the needle stick from the pain of the infiltration. Moreover, a complete clinical study of sensitivity on the infiltrated area was not conducted. CONCLUSIONS: Data obtained from this study may contribute to improve local infiltration anesthesia in ambulatory phlebectomy and other phlebologic procedures.

Association between nutrient intake and peripheral artery disease: results from the InCHIANTI study.

BACKGROUND: Little is known about the relationship between dietary patterns and peripheral arterial disease (PAD). Our aim was to estimate the association between nutrient intake and diagnosis of PAD. METHODS AND RESULTS: We assessed the nutrient intake of 1251 home-dwelling subjects enrolled in the InCHIANTI study, mean age 68 years (S.D.: 15). We explored the relationship between nutrient intake, obtained through the European Prospective Investigation into Cancer and Nutrition (EPIC) questionnaire, and PAD, defined as an ankle-brachial index (ABI)<0.90. After adjustment for potential confounders, we found a reduction of the risk of having an ABI<0.90 associated with vegetable lipid intake>or=34.4 g/day (OR: 0.39; 95% CI: 0.16-0.97), Vitamin E intake>or=7.726 mg/day (OR: 0.37; 95% CI 0.16-0.84) and higher serum HDL cholesterol concentration (OR: 0.76; 95% CI: 0.63-0.92 for 10mg/dl increase). Age (OR: 1.11; 95% CI 1.07-1.14 for 1 year increase), smoking (OR: 1.03; 95% CI: 1.01-1.04 for 10 packs/year increase) and pulse pressure (OR: 1.11; 95% CI: 1.03-1.19 for 5 mmHg increase) were associated with an increased risk of PAD. CONCLUSIONS: A higher intake of vegetable lipids, Vitamin E and higher concentrations of serum HDL cholesterol characterize subjects free from PAD. Prospective studies are needed to verify whether this dietary pattern and/or interventions aimed at increasing HDL cholesterol exert some protective effect against PAD.

Comparative effects of lercanidipine, lacidipine, and nifedipine gastrointestinal therapeutic system on blood pressure and heart rate in elderly hypertensive patients: the ELderly and LErcanidipine (ELLE) study.

This study was conducted to compare the antihypertensive efficacy and safety of lercanidipine with those of lacidipine and nifedipine gastrointestinal therapeutic systems in patients aged 65 years or above with mild-to-moderate hypertension. Patients were randomized to receive lercanidipine 5 mg, lacidipine 2 mg, or nifedipine 30 mg for 24 weeks. After 2 weeks, the dose was doubled in non-responding patients. At 24 weeks, blood pressure was significantly reduced in the three treatment groups. The decrease in systolic blood pressure was similar in all three groups. The decrease in diastolic blood pressure in the lercanidipine group (-18.3 mmHg) was comparable to that in the nifedipine group (-17.7 mmHg), but exceeded that in the lacidipine group (-16.6 mmHg). The incidence of adverse drug reactions (ADRs) was lowest in the lercanidipine group (19.4%) compared with the nifedipine group (28.4%) and the lacidipine group (27.1%). In particular, edema was least frequent in the lercanidipine group (2.8%) compared with the lacidipine group (7.5%) and the nifedipine group (10.1%). These data demonstrate that lercanidipine is effective in lowering blood pressure in older adult hypertensive patients while maintaining a superior tolerability and safety profile.
