A most discussed topic of the new decade, COVID-19 is an infectious disease caused by the recently discovered SARS-CoV-2. With an exceedingly high transmission rate, COVID-19 has affected almost all the countries in the world. Absent any vaccine or specific treatment, the humanity is left with nothing but the legacy method of quarantine. However, quarantine can only be effective when combined with early diagnosis of suspected cases. With their high sensitivity and unmatched specificity, biosensors have become an area of interest for development of novel diagnostic methods. Compared to the more traditional diagnostics, nanobiotechnology introduces biosensors as different diagnostics with greater versatility in application. Today, a growing number of analytes are being accurately identified by these nanoscopic sensing machines. Several reports of validated application with real samples further strengthen this idea. As of recent, there has been a rise in the number of studies on portable biosensors. Despite the slow progression, certain devices with embedded biosensors have managed to be of diagnostic value in several countries. The perceptible increase in development of mobile platforms has revolutionized the healthcare delivery system in the new millennium. The present article reviews the most recent advancements in development of diagnostic nanobiosensors and their application in the clinical fields. KEY POINTS • There is no specific treatment for highly transmissible SARS-CoV-2. • Early diagnosis is critical for control of pandemic. • Highly sensitive/specific nanobiosensors are emerging assets against COVID-19.Hepatitis B virus (HBV) affects approximately 68 million people in China, and 10-15% of adults infected with HBV develop chronic hepatitis B, liver cirrhosis, liver failure or hepatocellular carcinoma (HCC). HLA-DPB1 gene polymorphism and expression have been shown to be associated with HBV infection susceptibility and spontaneous clearance. The aim of this study is to evaluate the role of HLA-DPB1 gene polymorphism in HBV infection. HLA-DPB1 and rs9277535 polymorphisms were investigated in 259 patients with HBV infection and 442 healthy controls (HCs) using sequence-based typing. The mRNA of HLA-DPB1 was measured by real-time polymerase chain reaction. HLA-DPB1 genes and rs9277535 polymorphisms were all associated with HBV infection in the Sichuan Han population. rs9277535A and HLA-DPB1*0402 played a protective role against HBV infection. rs9277535G and DPB1*0501 were associated with susceptibility to HBV infection. rs9277535GG had significantly higher HLA-DPB1 mRNA expression in the HBV infection group compared with the HC group. HLA-DPB1*0501 and HLA-DPB1*2101 had significantly lower mRNA expression in the HBV infection group compared with the HC group. The meta-analysis revealed that HLA-DPB1*0201, HLA-DPB1*0202, HAL-DPB1*0401 and HLA-DPB1*0402 protected against HBV infection, while HLA-DPB1*0501, HLA-DPB1*0901, and HLA-DPB1*1301 were risk factors for susceptibility to HBV infection. HLA-DPB1*0201, HLA-DPB1*0202, and HLA-DPB1*0401 were associated with HBV spontaneous clearance, while HLA-DPB1*0501 was associated with chronic HBV infection. HLA-DPB1 alleles and rs9277535 have a major effect on the risk of HBV infection, and HBV infection is associated with lower HLA-DPB1 expression. HLA-DPB1 alleles have an important role in HBV susceptibility and spontaneous clearance.Mitochondria supply cellular energy through oxidative phosphorylation and fulfill numerous additional functions that are fundamental to cellular homeostasis and stress responses. Mitochondrial malfunction, arising from inherent defects of the organelle itself, aging, or acute or chronic stress, can cause substantial damage to organismal health. For instance, mitochondrial malfunction contributes to inflammation, neurodegeneration, tumorigenesis and cardiovascular diseases. Therefore, various quality control mechanisms exist that support a functional mitochondrial organelle compartment. The CMLS Forum Reviews introduced here present a collection of articles covering select topics on basic mechanisms and pathophysiological contexts of mitochondrial damage control.
Capsular contracture (CC) is a significant complication and major reason for revision in breast augmentation. Many studies indicate that most bacteria found in contracted capsules originate from the skin, especially that of the nipple-areolar complex (NAC). selleck chemicals llc To prevent implant contamination, protocols without a periareolar incision have been proposed and have become a limitation for breast augmentation. We sought to propose a strategy of proper skin management for periareolar incisions to prevent implant contamination and biofilm-related CC.

The analyses in this study are based on data collected from February 2017 to July 2020. A total of 129 patients were included, and they were randomized into two groups. The control group was subjected to no skin treatment before the surgery, and the treatment group underwent preoperative cleaning and disinfection of the NAC. We collected bacteriologic swabs used to rub the skin of the NAC and chest after draping and suturing from the control and treatment groups. We asng a periareolar incision or any other approach, even other surgery, could be a safe procedure.

Gait Profile Score (GPS) was validated as quality measure for the Gait Analysis (GA) in several patholgies, but GPS was never compared with clinical scales in post-stroke patients.

The aim of the study was to quantify functional limitation of post-stroke hemiparetic patients using clinical-functional scales and GPS and to assess the presence of correlation between GPS and the clinical-based outcome scales.

Thirty-three patients were assessed with the Berg Balance Scale (BBS), Trunk Impairment Scale (TIS), Functional Ambulation Category (FAC), Functional Independence Measure (FIM) and Ten-Meter Walk Test (10-MWT); GPS was obtained by GA.

GPS showed a fair relationship with FAC (p = 0.017; r = -0.412), TIS (p = 0.011, r = -0.436) and 10-MWT (p = 0.009, r =  0.49) and good correlation with BBS (p = 0.001; r = -0.561). The three regression models were statistically significant Model 1 showed that FAC, GPS and FIM had a statistically significant effect in the determination of the BBS, in model 2 and 3, FIM presented a statistically significant effect on TIS determination.

GPS seems to be an independent linear predictor of balance performance in stroke patient, and GVSs on sagittal plane might help clinicians to investigate the acquired compensatory strategies.

To evaluate existing evidence from published systematic reviews for the effectiveness of rehabilitation interventions in patients with lymphoma.

A comprehensive literature search was conducted using medical/health science databases up to 1 October 2020. Bibliographies of pertinent articles, journals and grey literature were searched.

Two reviewers independently selected and reviewed potential reviews for methodological quality and graded the quality of evidence for outcomes using validated tools. Any discrepancies were resolved by final group consensus.

Twelve systematic reviews (n = 101 studies, 87,132 patients with lymphoma) evaluated 3 broad categories of rehabilitation interventions (physical modalities, nutrition and complementary medicine). Most reviews were of moderate-to-low methodological quality. The findings suggest moderate-quality evidence for exercise programmes for improved fatigue and sleep disturbance; low-quality evidence for exercise therapy alone and qigong/tai chi for improved symptoms and overall quality of life, and an inverse association between sunlight/ultraviolet radiation exposure and incidence of non-Hodgkin's lymphoma; and very low-quality evidence for beneficial effects of yoga for sleep disturbances. Association between physical activity and lymphoma risk is indistinct.

Despite a range of rehabilitation modalities used for patients with lymphoma, high-quality evidence for many is sparse. Beneficial effects of exercise programmes were noted for fatigue, psychological symptoms and quality of life. More research with robust study design is required to determine the effective rehabilitation approaches.

However, many partially clonal eukaryotes exhibit life cycles in which somatic development occurs in both haploid and diploid individuals (haplodiplontic life cycles). Here, we studied how haplodiplontic life cycles and partial clonality structurally constrain, as immutable parameters, the reshuffling of genetic diversity and its dynamics in populations over generations. We assessed the distribution of common population genetic indices at different proportions of haploids, rates of clonality, mutation rates, and sampling efforts. Our results showed that haplodiplontic life cycles alone in finite populations affect effective population sizes and the ranges of distributions of population genetic indices. With nonoverlapping generations, haplodiplonty allowed the evolution of 2 temporal genetic pools that may diverge in sympatry due to genetic drift under full sexuality and clonality. Partial clonality in these life cycles acted as a homogenizing force between those 2 pools. Moreover, the combined effects of proportion of haploids, rate of clonality, and the relative strength of mutation versus genetic drift impacts the distributions of population genetics indices, rendering it difficult to transpose and use knowledge accumulated from diplontic or haplontic species. Finally, we conclude by providing recommendations for sampling and analyzing the population genetics of partially clonal haplodiplontic taxa.Electronic medication monitoring devices (EMD) have been used as a gold standard for assessing medication adherence. We used a wireless EMD (SimpleMed+), assessed its usability in patients after kidney transplantation (KTx), evaluated adherence, and analyzed concordance with other adherence measures. Fifty-five patients (53% female, mean age 46 years) at least 6 months after KTx agreed to use the EMD over a period of 8 weeks. Self-reported adherence was measured with the BAASIS, and immunosuppressant trough level variability was assessed prior to and again during the study period. Fourteen patients stopped using the EMD or were low users ( less then 70%). These non-completers reported that using the EMD would interfere with their daily activities. Taking-adherence of the completers was high with 98.3% (±1.9) over the entire study period. Timing-adherence was somewhat lower (94.6% ± 7.9) and decreased during the second half of the study. We found statistically significant correlations between EMD results and self-reported adherence with moderate effect sizes, but no significant association with trough level variability.
