Renal functional reserve (RFR), defined as the difference between stress and resting glomerular filtration rate (GFR), may constitute a diagnostic tool to identify patients at higher risk of developing acute kidney injury or chronic kidney disease. Blunted RFR has been demonstrated in early stages of hypertension and has been attributed to impaired vascular reactivity due to an overactive sympathetic nervous system (SNS).
The purpose of this study was to investigate whether RFR correlates with other phenotypes expressing overactivity of the SNS in patients with essential hypertension and preserved renal function.
Thirty-six patients with untreated essential hypertension and a GFR >60 mL/min/1.73 m2 were enrolled. The following parameters were measured RFR, 24-h ambulatory blood pressure (BP) profile, a treadmill stress test, and an echocardiographic examination. Urine and venous samples were obtained at specific time points for the determination of clinical parameters, and both resting and stress GFRrved GFR, reduced RFR is related to nondipping BP phenotype as well as to attenuated exercise HR response. Overactivity of the SNS may be a common pathway. Since loss of RFR may represent a risk factor for acute or chronic kidney injury, hypertensive patients with blunted RFR might need a more careful renal follow-up.The cerebellum has a highly conserved internal circuitry, but varies greatly in size and morphology within and across species. Despite this variation, the underlying volumetric changes among the layers of the cerebellar cortex or their association with Purkinje cell numbers and sizes is poorly understood. Here, we examine intraspecific scaling relationships and variation in the quantitative neuroanatomy of the cerebellum in Japanese quail (Coturnix japonica) selected for high or low reproductive investment. As predicted by the circuitry of the cerebellum, the volumes of the constituent layers of the cerebellar cortex were strongly and positively correlated with one another and with total cerebellar volume. The number of Purkinje cells also significantly and positively co-varied with total cerebellar volume and the molecular layer, but not the granule cell layer or white matter volumes. Purkinje cell size and cerebellar foliation did not significantly covary with any cerebellar measures, but differed significantly between the selection lines. Males and females from the high-investment lines had smaller Purkinje cells than males and females from the low-investment lines and males from the high-investment lines had less folded cerebella than quail from the low-investment lines. These results suggest that within species, the layers of the cerebellum increase in a coordinated fashion, but Purkinje cell size and cerebellar foliation do not increase proportionally with overall cerebellum size. In contrast, selection for differential reproductive investment affects Purkinje cell size and cerebellar foliation, but not other quantitative measures of cerebellar anatomy.
Topographical disorientation is one of the early symptoms of Alzheimer's disease (AD). The nature of this symptom, however, remains unclear.
The aim of the study was to investigate egocentric and allocentric spatial cognition in patients with amnestic mild cognitive impairment (aMCI) and early AD.
The participants consisted of normal healthy volunteers (n = 23), patients with aMCI (n = 26), and patients with early AD (n = 22). We administered the card placing test (CPT), in which a subject was required to recreate an array of 3 cards, each of which was randomly placed on 8 grids around the individual, before (part A) and after (part B) the individual's rotation. With this design, the CPT can reveal an individual's ability to represent spatial information either egocentrically (CPT-A) or allocentrically (CPT-B). A qualitative analysis of errors in performing the CPT was also conducted.
Compared with the controls, the aMCI patients showed significantly poorer CPT-B performance, while there was no significant difference in CPT-A performance between these 2 groups. In contrast, the AD patients demonstrated significantly poorer performance on both the CPT-A and CPT-B than the controls and aMCI patients. There was no significant difference in the profile of errors on the CPT-B between the controls and aMCI patients, whereas there was a notable difference in those on the CPT-A between the controls and AD patients and the aMCI and AD patients.
Allocentric spatial cognition is selectively impaired in aMCI patients, while an egocentric spatial cognition is additionally impaired in AD patients.
Allocentric spatial cognition is selectively impaired in aMCI patients, while an egocentric spatial cognition is additionally impaired in AD patients.Acquired factor V deficiency (AFVD) is a rare autoimmune bleeding disorder. Unlike acquired hemophilia, bypass therapies with recombinant activated factor VII and activated prothrombin complex concentrates are ineffective for severe bleeding due to AFVD. Although several treatment strategies have been attempted, a standard of care for severe hemorrhage induced by AFVD is lacking. Herein, we report a case of AFVD with severe bleeding that responded to plasma exchange (PE) combined with immunosuppression. We also reviewed previously reported AFVD cases with severe hemorrhage and suggest that PE may be an effective initial treatment for AFVD-induced severe hemorrhage.
Regular consumption of sugar-sweetened beverages (SSB) can increase the risk for obesity, type 2 diabetes, cardiovascular disease, and dental caries. Interventions that alter the physical or social environment in which individuals make beverage choices have been proposed to reduce the consumption of SSB.
We included randomised controlled, non-randomised controlled, and interrupted time series studies on environmental interventions, with or without behavioural co-interventions, implemented in real-world settings, lasting at least 12 weeks, and including at least 40 individuals. Studies on the taxation of SSB were not included, as these are subject of a separate Cochrane review. We used standard Cochrane methods for data extraction, risk of bias assessment, and evidence grading and synthesis. Searches were updated to January 24, 2018.
We identified 14,488 unique records and assessed 1,030 full texts for eligibility. We included 58 studies comprising a total of 1,180,096 participants and a median length ofts of interventions suitable for large-scale implementation, and interventions and settings not yet studied thoroughly.
With observed benefits outweighing observed harms, we suggest that environmental interventions to reduce the consumption of SSB be considered as part of a wider set of measures to improve population-level nutrition. Implementation should be accompanied by evaluations using appropriate methods. Future studies should examine population-level effects of interventions suitable for large-scale implementation, and interventions and settings not yet studied thoroughly.Currently, there is no clear agreement on the definition and conceptualization for psychological resilience (PR) in old age. Adopting a pragmatic view, this article elucidates the definition and conceptualization of PR by (1) extracting existing PR concepts that are relevant to aging, and (2) elucidating the contributing and delimiting factors for developing and sustaining PR as guided by the biopsychosocial framework. In addition, a comprehensive review of the tools used to measure PR was conducted to examine how scholars have conceptualized PR. Consequently, the renewed understanding defines PR as an emergent construct which is malleable, enduring, and can be developed and sustained by a dynamic interplay of biological, psychological, spiritual, and social factors. Correlates in terms of physical and mental well-being in the context of aging are identified.
Urachal cancer (UrC) is a rare but aggressive cancer. Due to its low incidence, structured epidemiological data have only rarely been reported. To date, no valid data on UrC are available for the German population.
Data on incidence and relative 5-year survival of urachal lesions (ICD-10 C67.7) were collected from all population-based cancer registries in Germany, provided by the Robert Koch-Institut (RKI). Data were anonymized and included age, sex, and general histology (ICD-O-3). For comparison, a similar inquiry of the "Surveillance, Epidemiology, and End Results program" (SEER-18) database for the USA was conducted.
From 2011 to 2015, a total of 154 and 152 cases of UrC were reported for Germany (RKI) and the USA (SEER-18 area), respectively. Age-standardized incidence was 0.32/1,000,000 age-standardized cases/year in both cohorts, and elderly persons were more often affected. The major histological type was adenocarcinoma (64.9 and 81.6%). Ferrostatin-1 Relative 5-year survival was 54.8% (CI 45.0-64.6) in Germaan population.
High-risk human papillomavirus (HR HPV) is found to be responsible for 4.5% of cancer in general, primarily cervical cancer. We aim here to highlight the prevalence and genotypes of HR HPV and correlate its association with Pap tests' results, which are still not well known in the Eastern Province of Saudi Arabia.
Over 7 years (2013-2019), the results of 164 Saudi women coinvestigated for HR HPV along with Pap tests were collected from the archive of King Fahd University Hospital. Only women who had atypical squamous cells of undetermined significance (ASCUS) on the Pap test and those at elevated risk of infection were cotested for HR HPV; otherwise, the Pap test was the only screening modality for cervical cancer. Data were organized and statistically analyzed using IBM SPSS v26.
Out of 164 Saudi women, 14.5% (n = 24/164) showed positive results for HR HPV (8 patients had HPV16 and 2 had both HPV16 and HPV18/45, while the remaining 14 had other HR HPV); among them, 41.5% (n = 10/24) had an abnormal Papncer.
HR HPV frequency and genotype distribution, in this study, might reflect a different regional infection pattern. The high association of HR HPV with negative cytology emphasizes the need to add the HR HPV test to screening modalities of cervix cancer.
Tetrahydrocurcumin (THC) is the major active metabolite of curcumin, which is a dietary factor derived from Curcuma species. Our previous study demonstrated a significant beneficial effect of THC in mice with allergic asthma. Glucocorticosteroids (GCs) are commonly used drugs in asthma. Whether THC supplementation could promote the beneficial effects of GC therapy on asthma has not yet been reported. The current study aimed to investigate the combined efficacy of GC and THC treatment in a mouse model of allergic asthma.
BALB/c mice were randomly divided into 5 groups the control group, ovalbumin (OVA)-induced group, and OVA-induced mice treated with dietary THC only, intraperitoneal injection of dexamethasone (DEX) only, or THC combined with DEX. The nasal symptoms, histopathological alterations of lung tissues, lung cytokine production, and Th cell subsets were assessed.
THC or DEX had beneficial effects on nasal symptoms and pathological lung changes, and the therapeutic effects between THC and DEX treatment were comparable.
