Laparoscopic Hartmann’s Reversal: Application of a Single-Port Approach Through the Colostomy Site

Purpose Recently, laparoscopic reversal of Hartmann’s colostomy was performed with favorable outcomes by many surgeons. We partially applied the concepts of single-port laparoscopic procedure through the colostomy site to remove intraperitoneal adhesion during initial step of the laparoscopic Hartmann’s reversal. This study aimed to evaluate the feasibility and safety of the laparoscopic reversal of Hartmann’s colostomy with the application of single-port laparoscopic techniques through the colostomy site. Methods From October 2008 to November 2018, the laparoscopic Hartmann’s reversal was attempted in 20 patients. After colostomy take-downs, the single-port device was installed at the colostomy site and the single-port laparoscopic procedure was performed to remove intraperitoneal adhesions to provide space for additional trocars. After additional trocars were inserted, the descending colon and rectal stump were mobilized, and the colorectal anastomosis was completed. We retrospectively reviewed the medical records and analyzed the data to identify the perioperative complication rates as the primary outcome. Results Of the 20 patients, 3 patients (15.0%) had open conversions due to severe adhesions. Intraoperative small bowel injuries occurred in 2 patients (10.0%) and these were repaired through the colostomy site. Postoperative complications developed in 4 patients (20.0%) and were managed with medical treatments or wound closures under local anesthesia. Conclusion The single-port laparoscopic procedure through the colostomy site is sufficiently safe in order to complete the Hartmann’s reversal. We recommend that the colostomy site should be used as the access route into the abdominal cavity for the Hartmann’s reversal.
Hydrolysis of Np(IV) and Pu(IV) and their complexation by aqueous Si(OH)4

Summary The hydrolysis and interaction of Np(IV) and Pu(IV) with orthosilicic acid, Si(OH)4, were studied in 0.1–1.0 M ionic strength aqueous solutions. Spectrophotometry was used to study these reactions at about 10–4 M Np(IV) and Pu(IV) concentrations. The first hydrolysis constants, Khydr, agree with the majority of earlier spectrophotometric and potentiometric data. The absorption spectra of NpOH3+ and PuOH3+ were obtained by spectral deconvolution. Reasons to explain the overestimation of Khydr obtained by other methods [by extraction of trace amounts of Np(IV) and Pu(IV) and by solubility] are discussed. Formation of the complexes NpOSi(OH)33+ and PuOSi(OH)33+ is demonstrated in the presence of 0.005–0.016 M Si(OH)4 in the p[H+] range 1.0–2.2 and 0.3–1.4, respectively. Measured values of equilibrium constants of the reaction M4+ + Si(OH)4 ↔ MOSi(OH)33+ + H+ at ionic strength I=1.0 are lg K1 = 0.41±0.02 and 1.04±0.04, respectively, for Np(IV) and Pu(IV). The stability constants of the NpOSi(OH)33+ and PuOSi(OH)33+ complexes, recalculated to zero ionic strength, are lg β10 = 11.2 and 11.8, respectively. The correlation between Khydr and K1, as observed for all earlier studied metal ions, also occurs for both Np(IV) and Pu(IV).
Intrafamilial Phenotypic Variability of Collagen VI-Related Myopathy Due to a New Mutation in the COL6A1 Gene

A family of five male siblings (three survivors at 48, 53 and 58 years old; two deceased at 8 months old and 2.5 years old) demonstrating significant phenotypic variability ranging from intermediate to the myosclerotic like Bethlem myopathy is presented. Whole-exome sequencing (WES) identified a new homozygous missense mutation chr21:47402679 T > C in the canonical splice donor site of the second intron (c.227 + 2T>C) in the COL6A1 gene. mRNA analysis confirmed skipping of exon 2 encoding 925 amino-acids in 94–95% of resulting transcripts. Three sibs presented with intermediate phenotype of collagen VI-related dystrophies (48, 53 and 2.5 years old) while the fourth sibling (58 years old) was classified as Bethlem myopathy with spine rigidity. The two older siblings with the moderate progressive phenotype (48 and 53 years old) lost their ability to maintain a vertical posture caused by pronounced contractures of large joints, but continued to ambulate throughout life on fully bent legs without auxiliary means of support. Immunofluorescence analysis of dermal fibroblasts demonstrated that no type VI collagen was secreted in any of the siblings’ cells, regardless of clinical manifestations severity while fibroblast proliferation and colony formation ability was decreased. The detailed genetic and long term clinical data contribute to broadening the genotypic and phenotypic spectrum of COL6A1 related disease.
A Wide Spectrum of Genetic Disorders Causing Severe Childhood Epilepsy in Taiwan: A Case Series of Ultrarare Genetic Cause and Novel Mutation Analysis in a Pilot Study

Background: Pediatric epileptic encephalopathy and severe neurological disorders comprise a group of heterogenous diseases. We used whole-exome sequencing (WES) to identify genetic defects in pediatric patients. Methods: Patients with refractory seizures using ≥2 antiepileptic drugs (AEDs) receiving one AED and having neurodevelopmental regression or having severe neurological or neuromuscular disorders with unidentified causes were enrolled, of which 54 patients fulfilled the inclusion criteria, were enrolled, and underwent WES. Results: Genetic diagnoses were confirmed in 24 patients. In the seizure group, KCNQ2, SCN1A, TBCID 24, GRIN1, IRF2BPL, MECP2, OSGEP, PACS1, PIGA, PPP1CB, SMARCA4, SUOX, SZT2, UBE3A, 16p13.11 microdeletion, [4p16.3p16. 1(68,345–7,739,782)X1, 17q25.1q25. 3(73,608,322–81,041,938)X3], and LAMA2 were identified. In the nonseizure group, SCN2A, SPTBN2, DMD, and FBN1 were identified. Ten novel mutations were identified. The recurrent genes included SCN1A, KCNQ2, and TBCID24. Male pediatric patients had a significantly higher (57% vs. 29%; p < 0.05, odds ratio = 3.18) yield than their female counterparts. Seventeen genes were identified from the seizure groups, of which 82% were rare genetic etiologies for childhood seizure and did not appear recurrently in the case series. Conclusions: Wide genetic variation was identified for severe childhood seizures by WES. WES had a high yield, particularly in male infantile patients.
Antibiofilm Activity of Heather and Manuka Honeys and Antivirulence Potential of Some of Their Constituents on the DsbA1 Enzyme of Pseudomonas aeruginosa

Heather honey was tested for its effect on the formation of biofilms by Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Enterococcus faecalis, Salmonella Enteriditis and Acinetobacter baumanii in comparison with Manuka honey. At 0.25 mg/mL, Heather honey inhibited biofilm formation in S. aureus, A. baumanii, E. coli, S. Enteriditis and P. aeruginosa, but promoted the growth of E. faecalis and K. pneumoniae biofilms. Manuka honey inhibited biofilm formation in K. pneumoniae, E. faecalis, and S. Enteriditis, A. baumanii, E. coli and P. aeruginosa, but promoted S. aureus biofilm formation. Molecular docking with Autodock Vina was performed to calculate the predictive binding affinities and ligand efficiencies of Manuka and Heather honey constituents for PaDsbA1, the main enzyme controlling the correct folding of virulence proteins in Pseudomonas aeruginosa. A number of constituents, including benzoic acid and methylglyoxal, present in Heather and/or Manuka honey, revealed high ligand efficiencies for the target enzyme. This helps support, to some extent, the decrease in P. aeruginosa biofilm formation observed for such honeys.
Perilipin 5 S155 phosphorylation by PKA is required for the control of hepatic lipid metabolism and glycemic control

Perilipin 5 (PLIN5) is a lipid-droplet-associated protein that coordinates intracellular lipolysis in highly oxidative tissues and is thought to regulate lipid metabolism in response to phosphorylation by protein kinase A (PKA). We sought to identify PKA phosphorylation sites in PLIN5 and assess their functional relevance in cultured cells and the livers of mice. We detected phosphorylation on S155 and identified S155 as a functionally important site for lipid metabolism. Expression of phosphorylation-defective PLIN5 S155A in Plin5 null cells resulted in decreased rates of lipolysis and triglyceride-derived fatty acid oxidation. FLIM-FRET analysis of protein-protein interactions showed that PLIN5 S155 phosphorylation regulates PLIN5 interaction with adipose triglyceride lipase at the lipid droplet, but not with α-β hydrolase domain-containing 5. Re-expression of PLIN5 S155A in the liver of Plin5 liver-specific null mice reduced lipolysis compared with wild-type PLIN5 re-expression, but was not associated with other changes in hepatic lipid metabolism. Furthermore, glycemic control was impaired in mice with expression of PLIN5 S155A compared with mice expressing PLIN5. Together, these studies demonstrate that PLIN5 S155 is required for PKA-mediated lipolysis and builds on the body of evidence demonstrating a critical role for PLIN5 in coordinating lipid and glucose metabolism.
Regionally diverse astrocyte subtypes and their heterogeneous response to EAE

Astrocytes fulfil many functions in the central nervous system (CNS), including contribution to the blood brain barrier, synapse formation, and trophic support. In addition, they can mount an inflammatory response and are heterogeneous in morphology and function. To extensively characterize astrocyte subtypes, we FACS‐isolated and gene expression profiled distinct astrocyte subtypes from three central nervous system regions; forebrain, hindbrain and spinal cord. Astrocyte subpopulations were separated based on GLAST/SLC1A3 and ACSA‐2/ATP1B2 cell surface expression. The local brain environment proved key in establishing different transcriptional programs in astrocyte subtypes. Transcriptional differences between subtypes were also apparent in experimental autoimmune encephalomyelitis (EAE) mice, where these astrocyte subtypes showed distinct responses. While gene expression signatures associated with blood–brain barrier maintenance were lost, signatures involved in neuroinflammation and neurotoxicity were increased in spinal cord astrocytes, especially during acute disease stages. In chronic stages of EAE, this reactive astrocyte signature was slightly decreased, while obtaining a more proliferative profile, which might be relevant for glia scar formation and tissue regeneration. Morphological heterogeneity of astrocytes previously indicated the presence of astrocyte subtypes, and here we show diversity based on transcriptome variation associated with brain regions and differential responsiveness to a neuroinflammatory insult (EAE).
Phytofabrication of cobalt oxide nanoparticles from Rhamnus virgata leaves extract and investigation of different bioactivities

The tunable cobalt oxide nanoparticles (CoONPs) are produced due to the phytochemicals present in Rhamnus virgata (RhV) leaf extract which functions as reducing and stabilization agents. The synthesis of CoONPs was confirmed using different analytical techniques: UV–Vis spectroscopy, X‐ray diffraction (XRD), scanning electron microscopy (SEM), dynamics light scatterings (DLS), Fourier‐transform infrared spectroscopy (FTIR), energy dispersive X‐ray, and Raman spectroscopy analyses. Furthermore, multiple biological activities were performed. Significant antifungal and antibacterial potentials have been reported. The in vitro cytotoxic assays of CoONPs revealed strong anticancer activity against human hepatoma HUH‐7 (IC50: 33.25 μg/ml) and hepatocellular carcinoma HepG2 (IC50: 11.62 μg/ml) cancer cells. Dose‐dependent cytotoxicity potency was confirmed against Leishmania tropica (KMH23); amastigotes (IC50: 58.63 μg/ml) and promastigotes (IC50: 32.64 μg/ml). The biocompatibility assay using red blood cells (RBCs; IC50: 4,636 μg/ml) has confirmed the bio‐safe nature of CoONPs. On the whole, results revealed nontoxic nature of RhV‐CoONPs with promising biological potentials.
Hypertension Prevalence Based on Blood Pressure Measurements on Two vs. One Visits: A Community-Based Screening Programme and a Narrative Review

We assessed the difference in the prevalence of hypertension in community surveys when blood pressure (BP) was measured on two vs. one visits and its impact on hypertension awareness, treatment and control proportions. A community-based BP screening programme was conducted in public places in the Seychelles (619 adults) and BP was rechecked a few days later among untreated participants with high BP (≥140/90 mmHg). A narrative review of the literature on this question was also conducted. Only 64% of untreated participants with high BP still had high BP at the second visit. The prevalence of hypertension in the whole sample decreased by 13% (from 33.8% to 29.5%) when BP was measured on two vs. one visits. These results concurred with our findings in our narrative review based on 10 surveys. In conclusion, the prevalence of hypertension can be markedly overestimated in community surveys when BP is measured on two vs. one visits. The overestimation could be addressed by measuring BP on a second visit among untreated individuals with high BP or, possibly, by taking more readings at the first visit. These findings have relevance for clinical practice, policy and surveillance.
Visual outcomes following everolimus targeted therapy for neurofibromatosis type 1‐associated optic pathway gliomas in children

Data for visual acuity (VA) after treatment of neurofibromatosis type 1‐associated optic pathway gliomas (NF1‐OPGs) are limited. We retrospectively collected VA, converted to logMAR, before and after targeted therapy with everolimus for NF1‐OPG, and compared to radiologic outcomes (14/18 with NF1‐OPG, 25 eyes [three without quantifiable vision]). Upon completion of treatment, VA was stable in 19 eyes, improved in four eyes, and worsened in two eyes; visual and radiologic outcomes were discordant. In summary, the majority of children with NF1‐OPG exhibited stabilization of their VA after everolimus treatment. A larger, prospective study will help delineate visual outcomes after targeted therapy.
Incidence and risk factors for hospital-acquired infection among paediatric patients in a teaching hospital: a prospective study in southeast Ethiopia

Objectives In order to maximise the prevention of hospital-acquired infections (HAIs) and antimicrobial resistance, data on the incidence of HAIs are crucial. In Ethiopia, data about the occurrence of HAIs among hospitalised paediatric patients are lacking. We aim to determine the incidence and risk factors of HAIs among paediatric patients in Ethiopia. Design A prospective cohort study. Setting A teaching hospital in southeast Ethiopia. Participants 448 hospitalised paediatric patients admitted between 1 November 2018 and 30 June 2019. Primary and secondary outcome measures Incidence and risk factors of hospital-acquired infections. Results A total of 448 paediatric patients were followed for 3227 patient days. The median age of the patients was 8 months (IQR: 2–26 months). The incidence rate of HAIs was 17.7 per 1000 paediatric days of follow-up; while the overall cumulative incidence was 12.7% (95% CI 9.8% to 15.8%) over 8 months. Children who stayed greater than 6 days in the hospital (median day) (adjusted risk ratio (RR): 2.58, 95% CI 1.52 to 4.38), and children with underlying disease conditions of severe acute malnutrition (adjusted RR: 2.83, 95% CI 1.61 to 4.97) had higher risks of developing HAIs. Conclusions The overall cumulative incidence of HAIs was about 13 per 100 admitted children. Length of stay in the hospital and underlying conditions of severe acute malnutrition were found to be important factors associated with increased risk of HAIs.
Inhibitory effects of the natural product esculetin on Phytophthora capsici and its possible mechanism.

Esculetin is an important plant-derived natural product that has multiple bioactivities and applications. Phytophthora capsici is a notorious plant pathogen capable of infecting a broad range of hosts. In this study, we evaluated the antifungal activity of esculetin against P. capsici. The baseline sensitivity of P. capsici to esculetin was established using 108 isolates collected from various geographical regions in the Jiangsu and Shandong Provinces of China. The median effective concentration (EC50) values for esculetin ranged from 2.08 to 16.46 μg/mL, with a mean of 6.87 ± 2.70 μg/mL, and were normally distributed. Furthermore, both zoospore production and germination were also strongly inhibited by esculetin. Importantly, esculetin exhibited protective as well as curative activities against P. capsici on tomato, and was capable of restricting the early infection of P. capsici on Nicotiana benthamiana. We found that the esculetin treatment led to cell membrane damage of P. capsici, as revealed by morphological observations and measurements of relative conductivity and malondialdehyde (MDA). Finally, our results also suggested esculetin may adversely affect P. capsici by inhibiting its DNA and protein synthesis. These findings will contribute to a broader evaluation of using esculetin to control diseases caused by P. capsici and towards a better understanding of its mode of action as a potential fungicide.
Microbiological and Antioxidant Activity of Phenolic Compounds in Olive Leaf Extract

According to many reports, phenolic compounds isolated from olive leaves have very good biological activities, especially antimicrobial. Presently, the resistance of microorganisms to antibiotics is greater than ever. Therefore, there are numerous recent papers about alternative solutions for inhibiting their influence on human health. Olive leaf is studied as an important source of antimicrobials with low cost and used in medicine. Numerous publications on involving green technologies for isolation of active compounds from olive leaves have appeared over the past few decades. The present review reports on current knowledge of the most isolated phenolic compounds from olive leaf extract as well as methods for their isolation and characterization. This paper uses recent research findings with a wide range of study models to describe the antimicrobial potential of phenolic compounds. It also describes the vast range of information about methods for determination of antimicrobial potential focusing on effects on different microbes. Additionally, it serves to highlight the role of olive leaf extract as an antioxidants and presents methods for determination of antioxidant potential. Furthermore, it provides an overview of presence of enzymes. The significance of olive leaves as industrial and agricultural waste is emphasized by means of explaining their availability, therapeutic and nutritional effects, and research conducted on this field.
Prediction of losses in induction machines: a challenge for the modelling approaches

This paper presents and discusses some numerical approaches for the simulation of induction machine behaviour under no-load conditions. All the approaches are based on the finite element solution of the electromagnetic field problem, including physical models of magnetic material and interaction with external circuits. The computed flux distributions enable the prediction of magnetic and additional losses, whose accuracy is discussed also in the light of the complexity of the used numerical technique.
My Privacy and Control Matter: Understanding Motivations for Using Untact Services

This study's aim was to uncover psychological and social motives for using untact services and to explore the relationships between identified motivations and attitudinal and continuous behavioral intention variables. We conducted a survey with 328 untact service users, and used exploratory and confirmatory factor analysis to find underlying motivations. The findings suggest that users of untact services have four primary motives. Individuals use untact services to protect their personal information (privacy), to increase their control over business transactions (control), to enjoy the process itself (fun), and to avoid uncomfortable interactions with employees (interaction avoidance). In addition, identified motivations and attitudes toward as well as continuing intention to use the services were all positively related. Among the motivations, control showed the strongest relationship with both attitude and continuance intention.
Repeated kidney re-transplantation in times of organ shortage – a critical review

Purpose of review Organ shortage forces those responsible to streamline allocation rules to provide a maximum of candidates with a graft and to optimize transplant outcome. Recently, repeated kidney re-transplantation was investigated in several studies with different analytic settings concerning the control group, the donors, parameters influencing outcome, and demographic characteristics. This review gives an overview on the candidates awaiting a repeated re-transplantation, summarizes the outcome, and comments on the relevance of these findings in the context of sustained organ shortage. Recent findings Repeated kidney re-transplantation is technically and immunologically feasible and the recipients’ survival is better compared to candidates remaining on dialysis or on the waiting-list. However, the outcome is mainly reported to be worse as compared to first or second kidney transplantation. Kidneys from living donors seem to have a favorable impact on outcome in this setting. Summary The survival benefit of repeated re-transplantation recipients over patients on dialysis demands for continuation of this procedure. Comprehensive registries are essential to continuously optimize allocation. Governmental authorities are obliged to set the course to increase organ donation rather than forcing transplant decision makers to withhold a third or fourth graft from any candidate.
Understanding COVID-19 vaccine demand and hesitancy: A nationwide online survey in China.

BACKGROUND This study attempts to understand coronavirus disease 2019 (COVID-19) vaccine demand and hesitancy by assessing the public's vaccination intention and willingness-to-pay (WTP). Confidence in COVID-19 vaccines produced in China and preference for domestically-made or foreign-made vaccines was also investigated. METHODS A nationwide cross-sectional, self-administered online survey was conducted on 1-19 May 2020. The health belief model (HBM) was used as a theoretical framework for understanding COVID-19 vaccination intent and WTP. RESULTS A total of 3,541 complete responses were received. The majority reported a probably yes intent (54.6%), followed by a definite yes intent (28.7%). The perception that vaccination decreases the chances of getting COVID-19 under the perceived benefit construct (OR = 3.14, 95% CI 2.05-4.83) and not being concerned about the efficacy of new COVID-19 vaccines under the perceived barriers construct (OR = 1.65, 95% CI 1.31-2.09) were found to have the highest significant odds of a definite intention to take the COVID-19 vaccine. The median (interquartile range [IQR]) of WTP for COVID-19 vaccine was CNY¥200/US$28 (IQR CNY¥100-500/USD$14-72). The highest marginal WTP for the vaccine was influenced by socio-economic factors. The majority were confident (48.7%) and completely confident (46.1%) in domestically-made COVID-19 vaccine. 64.2% reported a preference for a domestically-made over foreign-made COVID-19 vaccine. CONCLUSIONS The findings demonstrate the utility of HBM constructs in understanding COVID-19 vaccination intent and WTP. It is important to improve health promotion and reduce the barriers to COVID-19 vaccination.
