Frailty is an important condition in elderly individuals because it increases disability, morbidity, and mortality. The definition frailty from the Cardiovascular Health Study (CHS) criteria is used worldwide and defined as fulfilling 3 out of the 5 phenotypic criteria that indicate compromised energetics weakness, slowness, low level of physical activity, self-reported exhaustion, and unintentional weight loss.

This research aims to study the validity of 5 screening methods, e.g., Clinical Frailty Scale, simple FRAIL questionnaire, PRISMA-7 questionnaire, Time Up and Go Test (TUG), and Gérontopôle frailty screening tool (GFST), and compare those results with the definition of frailty by using the CHS criteria for screening frailty.

We conducted a cross-sectional study. The sample was 214 elderly individuals, aged ≥60 years, and living in the community. We used 5 screening tests and the Fried phenotype (CHS criteria) as a reference standard. Analysis of the sensitivity, specificity, PPV, NPV, LR+, LR-, the CHS criteria.
The simple FRAIL questionnaire and GFST have the highest sensitivity compared with the CHS criteria. All screening tests in this study have an accuracy of more than 80% compared with the CHS criteria.Calculating the number of spanning trees of a graph is one of the widely studied graph problems since the Pioneer Gustav Kirchhoff (1847). In this work, using knowledge of difference equations we drive the explicit formulas for the number of spanning trees in the sequence of some Nonahedral (nine faced polyhedral) graphs generated by triangle using electrically equivalent transformations and rules of the weighted generating function. Finally, we evaluate the entropy of graphs in this manuscript with different studied graphs with an average degree being 4, 5 and 6.Environmental pollution of heavy metals is increasingly becoming a problem and has become of great concern due to the adverse effects it is causing around the world. These inorganic pollutants are being discarded in our waters, soils and into the atmosphere due to the rapidly growing agriculture and metal industries, improper waste disposal, fertilizers and pesticides. This review shows how pollutants enter the environment together with their fate. Some metals affect biological functions and growth, while other metals accumulate in one or more different organs causing many serious diseases such as cancer. The pharmacokinetics and toxicological processes in humans for each metal is described. In summary, the review shows the physiological and biochemical effects of each heavy metal bioaccumulation in humans and the level of gravity and disquieting factor of the disease.[This corrects the article DOI 10.1016/j.heliyon.2020.e04204.].
In order to be able to design and implement control measures directed to the mosquito larva stages an understanding of the spatial and temporal distribution and its determinants in different malaria transmission settings is important. This study therefore, intended to determine the spatial and temporal distribution of
mosquito's larvae and its determinants in two urban sites with different transmission levels, in Tanzania.

This study was conducted in Dodoma and Morogoro regions in Tanzania. The study was an ecological study of repeated cross-sectional type. Searching for water bodies in the selected wards was done by going around all streets. Potential breeding sites were given unique identification numbers and larval sampling was done using the standard dipping method with a 350ml mosquito scoop and a calibrated pipette. RG2833 in vitro Visual identification of presence of larvae and its abundance in each sampling were used to describe the larvae density. A sample of
mosquitoes which emerged from collected larvae, 4.5%
0.5%
and 20%
while 2.5% of the samples could not be identified because DNA was not amplified


Type of water, distance from the breeding site to human settlement, light intensity and habitat origin were significant predictors of variation on the spatial and temporal distribution of Anopheles mosquito breeding sites. With increased global emphasis on control measures that targets mosquito immature stages; we recommend that larval control measures should be developed while considering the findings from this study.

Coincubation with medium-chain (C7-C11) perfluoroalkyl carboxylic acids (PFCAs), such as perfluoroheptanoic acid (PFHpA, C7), perfluorooctanoic acid (PFOA, C8), perfluorononanoic acid (PFNA, C9), perfluorodecanoic acid (PFDA, C10) and perfluoroundecanoic acid (PFUnDA, C11), significantly decreased BSP uptake by 27-55%, while coincubation with short- (C3-C6) and long-chain (C12-C14) PFCAs decreased the uptake only slightly. Dixon plotting suggested that PFOA, PFNA and PFDA competitively inhibited the BSP uptake with inhibition constant (Ki) values of 62.2 ± 1.3 μM, 35.3 ± 0.1 μM and 43.2 ± 0.3 μM, respectively. PFCAs with medium-chains could be substrates for OATPs, probably OATP2B1, which is the most abundantly expressed OATP isoform in Caco-2 cells.Clusters of patients who obtain cosmetic surgeries abroad have developed surgical site infections due to rapid growing non-tuberculous mycobacteria (NTM). These are usually treated with a combination of surgery and months of anti-mycobacterial therapy, but poor outcomes, including permanent scarring are common. We present a case of a 36-year-old female who developed a clarithromycin-resistant M. chelonae (CRMC) infection after undergoing breast augmentation in the Dominican Republic. She underwent debridement and explant of her silicone implants, but due to a series of complications including discordant antimicrobial susceptibility testing profiles, GI side effects, and then pregnancy, she was unable to receive typical multidrug anti-mycobacterial therapy after surgery. She received close clinical follow up and demonstrated full recovery without any evidence of recurrence of infection at 9 months of follow up. We searched the literature for cases of NTM surgical site infection after breast surgery. To our knowledge, this is the first case report of confirmed NTM breast implant infection being cured with surgery alone, and only the second report of clarithromycin resistant M.
