Dysbiosis of gut microbiota (GM) has been involved in the pathophysiology of arterial hypertension (HT), via a putative role of short chain fatty acids (SCFAs). Its role in the circadian regulation of blood pressure (BP), also called “the dipping profile”, has been poorly investigated. Sixteen male volunteers and 10 female partners were subjected to 24 h ambulatory BP monitoring and were categorized in normotensive (NT) versus HT, as well as in dippers versus non-dippers. Nuclear magnetic resonance (NMR)-based metabolomics was performed on stool samples. A 5-year comparative follow-up of BP profiles and stool metabolomes was done in men. Significant correlations between stool metabolome and 24 h mean BP levels were found in both male and female cohorts and in the entire cohort (R2 = 0.72, R2 = 0.79, and R2 = 0.45, respectively). Multivariate analysis discriminated dippers versus non-dippers in both male and female cohorts and in the entire cohort (Q2 = 0.87, Q2 = 0.98, and Q2 = 0.68, respectively). Fecal amounts of acetate, propionate, and butyrate were higher in HT versus NT patients (p = 0.027; p = 0.015 and p = 0.015, respectively), as well as in non-dippers versus dippers (p = 0.027, p = 0.038, and p = 0.036, respectively) in the entire cohort. SCFA levels were significantly different in patients changing of dipping status over the 5-year follow-up. In conclusion, stool metabolome changes upon global and circadian BP profiles in both genders.

Abstract Background and Aims Dysbiosis of gut microbiota (GM) has been involved in the pathophysiology of arterial hypertension (HT), via a putative role of food-derived short chain fatty acids (SCFAs). Among the clinical manifestations of HT, the absence of a significant drop in blood pressure (BP) overnight (i.e. non-dipping BP profile) has been associated with poor cardiovascular outcomes. The link between GM and non-dipping BP profile is unknown. Method After informed consent, 16 male patients and their female partners (n=10) were subjected to 24-hours ambulatory BP monitoring and were categorized in 2 groups: HT (n=7; 6 men) and normotension (NT) (n=19). According to the conventional night–day systolic BP ratio >0.9, 15 individuals (8 men and 7 women) were categorized as non-dippers. Metabolomics using Nuclear Magnetic Resonance was performed on stool samples, including the quantification of the 3 main SCFAs (i.e. acetate, propionate and butyrate). Results Multivariate analysis (principal component analyses (PCA) and partial least squares (PLS-DA)) of stool metabolomics were not able to statistically separate HT versus NT groups. However, this approach discriminated dippers versus non-dippers groups in both male and female cohorts (Q²=0.87 and 0.98, respectively), as well as in the entire cohort (Q²=0.68). As previously described, fecal amounts of acetate, propionate and butyrate were higher in HT patients than in NT patients in the entire cohort (p=0.027; p=0.015 and p=0.015, respectively). Fecal amounts of acetate, propionate and butyrate were also significantly higher in non-dippers versus dippers in the entire cohort (p=0.027; p=0.038 and p=0.036, respectively). Significant correlations between stool metabolomes and the 24h-mean BP levels were found in male and female cohorts (R²=0.63 and 0.79 respectively) as well as in the entire cohort (R²=0.54). Conclusion In conclusion, this 26-patient cohort highlights significant correlations between stool metabolome and (i) BP levels and (ii) non-dipping BP profile in both men and women.

Background: Control of blood pressure and reduction of cardiovascular risk factors are mandatory in patients with hypertension. The aim of this study was to determine the proportion of patients with controlled hypertension and to describe the cardiovascular risk profile in hypertensive patients followed by general practitioners (GPs) in Morocco. Methods: This national, observational, multicentre, prospective, longitudinal study of patients with newly diagnosed hypertension was carried out between September 2011 and December 2011. The use of antihypertensive drugs was evaluated at inclusion and after 3 months of follow up. Uncontrolled hypertension was defined as systolic blood pressure (SBP) ⩾ 140 mmHg or diastolic blood pressure (DBP) ⩾ 90 mmHg at 3 months of follow up. The SCORE scale issued by the European Society of Cardiology (ESC) was used to assess overall cardiovascular risk and probability of experiencing a cardiovascular event within 10 years. Results: A total of 909 hypertensive patients were recruited (62.4% female). Mean age was 56.8 ± 10.6 years. More than half of the patients (53.0%) were between 40–60 years and more than one-third (34.1%) were obese [body mass index (BMI) ⩾ 30 kg/m2]. There were significantly more obese females than males ( p < 0.001). Over half of the patients (52.5%) had a high or extremely high cardiovascular risk. Abdominal obesity (measured as waist circumference) was the most common cardiovascular risk factor (61.7%) followed by age (40.5%), dyslipidaemia (36.3%) and diabetes (34.3%). Mean SBP decreased from 168.1 ± 14.8 to 138.3 ± 13.2 mmHg ( p < 0.001) and mean DBP decreased from 93.0 ± 10.5 to 81.0 ± 8.6 mmHg ( p < 0.001) after 3 months of treatment. Control of blood pressure was achieved in only 46.8% of patients. Poor compliance (17.1%) and a lack of treatment efficacy (16.9%) were the two main reasons for not achieving the blood pressure target. Conclusions: More than half (53.2%) of the hypertensive patients in our study did not achieve adequate blood pressure control during the 3-month follow-up period and had a high cardiovascular risk. More effective management of hypertension is required in primary care.

Abstract Objective Distal sensory polyneuropathy (DSP) is a disabling consequence of HIV, leading to poor quality of life and more frequent falls in older age. Neuropathic pain and paresthesia are prevalent symptoms, however there are currently no known curative treatments and the longitudinal course of pain in HIV-associated DSP is poorly characterized. Methods This was a prospective longitudinal study of 265 PWH enrolled in the CNS HIV Antiretroviral Therapy Effects Research (CHARTER) study with baseline and 12-year follow-up evaluations. Since pain and paresthesia are highly correlated, statistical decomposition was used to separate the two symptoms at baseline. Multivariable logistic regression analyses of decomposed variables were used to determine the effects of neuropathy symptoms at baseline on presence and worsening of distal neuropathic pain at 12-year follow-up, adjusted for covariates. Results Mean age was 56 ± 8 years, and 21% were female at follow-up. Nearly the entire cohort (96%) was on antiretroviral therapy (ART) and 82% had suppressed (≤50 copies/mL) plasma viral loads at follow-up. Of those with pain at follow-up (n = 100), 23% had paresthesia at the initial visit. Decomposed paresthesia at baseline increased the risk of pain at follow-up (OR 1.56; 95% CI 1.18, 2.07), and decomposed pain at baseline predicted a higher frequency of pain at follow-up (OR 1.96 [1.51, 2.58]). Conclusions Paresthesias are a clinically significant predictor of incident pain at follow-up among aging PWH with DSP. Development of new therapies to encourage neuroregeneration might take advantage of this finding to choose individuals likely to benefit from treatment preventing incident pain.

The Relationship

BACKGROUND Phantom vibrations syndrome (PVS) and phantom ringing syndrome (PRS) are prevalent hallucinations during medical internship. Depression and anxiety are probably understudied risk factors of PVS and PRS. OBJECTIVE The aim of this study was to investigate the role of anxiety and depression on the relationship between working stress during medical internship and PVS and PRS. METHODS A prospective longitudinal study of 74 medical interns was carried out using repeated investigations of the severity of phantom vibrations and ringing, as well as accompanying symptoms of anxiety and depression as measured by Beck Anxiety Inventory and the Beck Depression Inventory before, at the 3rd, 6th, and 12th month during internship, and 2 weeks after internship. We conducted a causal mediation analysis to investigate the role of depression and anxiety in the mechanism of working stress during medical internship inducing PVS and PRS. RESULTS The results showed that depression explained 21.9% and 8.4% for stress-induced PRS and PVS, respectively. In addition, anxiety explained 15.0% and 7.8% for stress-induced PRS and PVS, respectively. CONCLUSIONS Our findings showed both depression and anxiety can explain a portion of stress-induced PVS and PRS during medical internship and might be more important in clinical practice and benefit to prevention of work-related burnout.

BackgroundThe aim was to examine the longitudinal evolution of depression and anosognosia in patients with probable Alzheimer's disease (AD).MethodSixty-two of a consecutive series of 116 AD patients that were examined with a structured psychiatric interview had a follow-up evaluation between one and two years after the initial evaluation.ResultsAt the initial evaluation 19% of the 62 patients had major depression, 34% had dysthymia, and 47% were not depressed. After a mean follow-up of 16 months, 58% of patients with major depression at the initial evaluation were still depressed, whereas only 28% of patients with initial dysthymia and 21% of the non-depressed patients were depressed at follow-up. During the follow-up period, all three groups showed similar declines in cognitive status and activities of daily living. At the initial evaluation, 39% of the patients had anosognosia, and there was a significant increment of anosognosia during the follow-up period.ConclusionsWhile dysthymia in AD is a brief emotional disorder, major depression is a longer-lasting mood change. Anosognosia is another prevalent disorder among AD patients, and increases with the progression of the illness.

The predictive role of high-sensitivity C-reactive protein (hs-CRP), number of tooth extractions, and oral infections for mortality in people with and without diabetes is unclear. This prospective cohort study is a 12 1/2-year follow-up of the Oslo II study, a health survey in 2000. In all, 12,764 men were invited. Health information was retrieved from 6434 elderly men through questionnaire information, serum measurements, and anthropometric and blood pressure measurements. Diabetes was reported by 425 men. Distinct differences were observed in baseline characteristics in individuals with and without diabetes. In the diabetes group, age and hs-CRP were statistically significant whereas in the nondiabetes group, age, hs-CRP, number of tooth extractions, tooth extractions for infections and oral infections combined, nonfasting glucose, systolic blood pressure, total cholesterol, regular alcohol drinking, daily smoking, and level of education were independent risk factors. The number of tooth extractions <5 was inversely related whereas more extractions increased the risk. Multivariate analyses showed that hs-CRP was a significant predictor in persons with diabetes and tooth extractions and oral infections combined; the number of teeth extracted and hs-CRP were for persons without diabetes. Infection and inflammation were associated with mortality in individuals both with and without diabetes.

Purpose Cancer-related cognitive impairment is an important problem for patients with breast cancer, yet its trajectory is not fully understood. Some previous cancer-related cognitive impairment research is limited by heterogeneous populations, small samples, lack of prechemotherapy and longitudinal assessments, use of normative data, and lack of generalizability. We addressed these limitations in a large prospective, longitudinal, nationwide study. Patients and Methods Patients with breast cancer from community oncology clinics and age-matched noncancer controls completed the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) at prechemotherapy and postchemotherapy and at a 6-month follow-up as an a priori exploratory aim. Longitudinal models compared FACT-Cog scores between patients and controls at the three assessments and adjusted for age, education, race, menopausal status, and baseline reading ability, anxiety, and depressive symptoms. A minimal clinically important difference cutoff determined percentages of impairment over time. Results Of patients, 581 patients with breast cancer (mean age, 53 years; 48% anthracycline-based regimens) and 364 controls (mean age, 53 years) were assessed. Patients reported significantly greater cognitive difficulties on the FACT-Cog total score and four subscales from prechemotherapy to postchemotherapy compared with controls as well as from prechemotherapy to 6-month follow-up (all P < .001). Increased baseline anxiety, depression, and decreased cognitive reserve were significantly associated with lower FACT-Cog total scores. Treatment regimen, hormone, or radiation therapy was not significantly associated with FACT-Cog total scores in patients from postchemotherapy to 6-month follow-up. Patients were more likely to report a clinically significant decline in self-reported cognitive function than were controls from prechemotherapy to postchemotherapy (45.2% v 10.4%) and from prechemotherapy to 6-month follow-up (36.5% v 13.6%). Conclusion Patients with breast cancer who were treated in community oncology clinics report substantially more cognitive difficulties up to 6 months after treatment with chemotherapy than do age-matched noncancer controls.
