Published: September 2022

IntroductionHuman Papillomavirus (HPV) vaccine has proven to play a major role in preventing sexually transmitted diseases and related cancers among both men and women. However, the coverage of the HPV vaccination is still limited.ObjectiveThe study aims to evaluate the awareness of HPV and HPV vaccine, as well as the willingness to take HPV vaccine, especially factors influencing vaccination willingness among male college students.MethodsWe conducted a cross-sectional investigation among male college students from six colleges in Jiangsu, China. A structured questionnaire was used to investigate the subjects' basic information, behavior habits, cognition of the HPV vaccine, and intention for HPV vaccination. Multivariate analysis modes were used to analyze the influencing factors of vaccine awareness and willingness.ResultsWe found that among 912 participants, only 24.34% of the participants had a “good knowledge” of HPV and HPV vaccine, and 34.54% showed a “positive attitude“ toward the HPV vaccine after obtaining knowledge of HPV and its vaccine. Factors such as immune persistence, side effects, pricing strategy, and participants' self-assessment of HPV infection were the main factors influencing the HPV vaccination.ConclusionStrengthening health education on the HPV vaccination and finding appropriate ways to solve the problem of ”vaccine hesitancy“ will be effective in improving the coverage of the HPV vaccine and preventing related diseases. In addition, the lifting of restrictions on HPV vaccination for men in China may also prove useful.

IntroductionSeasonal influenza, a contagious viral disease affecting the upper respiratory tract, circulates annually, causing considerable morbidity and mortality. The present study investigates the effectiveness of educational interventions to prevent influenza.MethodsWe searched PubMed/Medline, Embase, and Cochrane Controlled Register of Trials (CENTRAL) for relevant clinical studies up to March 1 2022. The following terms were used: “influenza,” “flu,” “respiratory infection,” “prevent,” “intervention,” and “education.”ResultsOut of 255 studies, 21 articles satisfied the inclusion criteria and were included in our study: 13 parallel randomized controlled trials (RCT) studies, two cross-over RCT studies, two cohort studies, and four quasi-experimental studies. A total of approximately 12,500 adults (18 years old or above) and 11,000 children were evaluated. Educational sessions and reminders were the most common interventions. The measured outcomes were vaccination rates, the incidence of respiratory tract infection (RTI), and preventive behaviors among participants. Eighteen out of 21 articles showed a significant association between educational interventions and the outcomes.ConclusionsThe included studies in the current systematic review reported the efficacy of health promotion educational interventions in improving knowledge about influenza, influenza prevention behaviors, vaccination rates, and decreased RTI incidence regardless of the type of intervention and the age of cases.

IntroductionRadial nerve lesions present a clinical entity that may lead to disability, psychological distress, and job loss, and thus requires great attention. Knowledge of the etiology and exact mechanism of the nerve impairment is of great importance for appropriate management of these patients, and there are only a few papers that focused on these features in patients with surgically treated radial nerve lesions. The lack of studies presenting the etiology and injury mechanisms of surgically treated radial nerve lesions may be due to a relatively small number of specialized referral centers, dispersion to low-flow centers, and a greater focus on the surgical treatment outcomes.AimThe aim of this study was to describe the etiological and epidemiological characteristics of patients with surgically treated radial nerve lesions of various origins.MethodsThis retrospective study evaluated 147 consecutive patients with radial nerve lesion, treated in the department during the last 20 years, from January 1, 2001, until December 31, 2020.ResultsThe majority of patients belonged to the working population, and 70.1% of them were male. Most commonly, the etiology of nerve lesion was trauma (63.3%) or iatrogenic injury (28.6%), while the less common origin was idiopathic (4.1%) or neoplastic (4.1%). The most frequent location of the lesion was in the upper arm, followed by the elbow and forearm. Fracture-related contusion was the most common mechanism (29.9%), followed by postoperative fibrosis (17.7%), lacerations (17.7%), and compression (15.6%).ConclusionBased on the fact that traumatic or iatrogenic injuries constitute the majority of cases, with their relevant mechanisms and upper arm predomination, it is crucial to raise awareness and understanding of the radial nerve injuries among orthopedic surgeons to decrease the numbers of these patients and properly preserve or treat them within the initial surgery.
Using in vitro bioassays to guide the development of safer bio-based polymers for use in food packaging
Authors: Harper Emma , Cunningham Eoin , Connolly Lisa 
Published: September 2022

Petroleum-based polymers traditionally used for plastic packaging production have been shown to leach dangerous chemicals such as bisphenol-A (BPA). Bio-based polymers are potentially safer alternatives, and many can be sustainably sourced from waste streams in the food industry. This study assesses bio-based polymers undergoing food packaging development for migration of endocrine disrupting leachates at the level of estrogen, androgen and progestagen nuclear receptor transcriptional activity. Reporter gene assays were coupled with migration testing, performed using standardised test conditions for storage and temperature. Test samples include nine bio-based polymers and four inorganic waste additives mixed with a traditional petroleum-based polymer, polypropylene. Thermoplastic starch material, polybutylene succinate, polycaprolactone, polybutylene adipate terephthalate (PBAT), two polylactic acid (PLA)/PBAT blends, polyhydroxybutyrate (PHB) and eggshell/polypropylene (10:90) presented no significant reduction in metabolic activity or hormonal activity under any test condition. Polypropylene (PP) presented no hormonal activity. Metabolic activity was reduced in the estrogen responsive cell line after 10 days migration testing of eggshell/polypropylene (0.1:99.9) in MeOH at 40°C, and PP in MeOH and dH20. Estrogenic agonist activity was observed after 10 days in poultry litter ash/polypropylene (10:90) in MeOH at 20°C and 40°C, poultry feather based polymer in MeOH and dH2O at 40°C, and eggshell/polypropylene (40:60) and PLA in dH2O at 40°C. Activity was within a range of 0.26–0.50 ng 17β-estradiol equivalents per ml, equating to an estrogenic potency of 3–∼2800 times less than the estrogenic leachate BPA. Poultry litter ash/polypropylene (10:90) in MeOH for 10 days presented estrogenic activity at 20°C and 40°C within the above range and anti-androgenic activity at 40°C. Progestagenic activity was not observed for any of the compounds under any test condition. Interestingly, lower concentrations of eggshell or PP may eliminate eggshell estrogenicity and PP toxicity. Alternatively eggshell may bind and eliminate the toxic elements of PP. Similarly, PLA estrogenic activity was removed in both PLA/PBAT blends. This study demonstrates the benefits of bioassay guidance in the development of safer and sustainable packaging alternatives to petroleum-based plastics. Manipulating the types of additives and their formulations alongside toxicological testing may further improve safety aspects.

Key Points

Proximal tubular secretion is a primary kidney function not reflected by GFRs.Secretion is rarely measured due to a paucity of validated markers. This study uses metabolomics to identify candidate endogenous solutes.Solutes were compared with the clearance of furosemide and penciclovir, two highly secreted medications, in 50 patients with and without CKD.

Background
The proximal tubules eliminate protein-bound toxins and drugs through secretion. Measurements or estimates of GFR do not necessarily reflect the physiologically distinct process of secretion. Clinical assessment of this important intrinsic kidney function requires endogenous markers that are highly specific for secretory transport.

Methods
We used metabolomics profiling to identify candidate markers of tubular secretory clearance in 50 participants from a kidney pharmacokinetics study. We measured metabolites in three sequential plasma samples and a concurrent 10-hour timed urine sample using hydrophilic interaction liquid chromatography/high-resolution mass spectrometry. We quantified the association between estimated kidney clearance and normalized plasma peak height of each candidate solute to the clearance of administered furosemide, a protein-bound, avidly secreted medication.

Results
We identified 528 metabolites present in plasma and urine, excluding pharmaceuticals. We found seven highly (>50%) protein-bound and 49 poorly bound solutes with clearances significantly associated with furosemide clearance and 18 solute clearances favoring an association with furosemide clearance by the 90th percentile compared with GFR. We also found four highly bound and 42 poorly bound plasma levels that were significantly associated with furosemide clearance.

Conclusions
We found several candidate metabolites whose kidney clearances or relative plasma levels are highly associated with furosemide clearance, an avidly secreted tracer medication of the organic anion transporters, highlighting their potential as endogenous markers of proximal tubular secretory clearance.

Aims. To develop an algorithm for assessing the stage of ﬁbrosis based on high-density endocardial mapping. To study the eﬀect of the stage of left atrial (LA) ﬁbrosis on the results of atrial ﬁbrillation (AF) catheter ablation.Methods. The study included 64 patients with paroxysmal or persistent AF, who underwent high-density LA mapping and catheter ablation. After the intervention procedure, we analyzed the electroanatomical maps of the left atrium, assessed the prevalence of low-voltage areas according to the developed algorithm. Patients were divided into 4 groups depending on the prevalence of areas of low voltage based on the Utah score.Results. The follow-up period was 14.5 ± 6.7 months. AF recurrence developed in 18 (28.1%) patients after the ablation procedure. AF recurrence after ablation was more frequent in patients with a low-voltage area of more than 20% than in patients with a low-voltage left atrial area of less than 20%, 6 (15.4%) versus 12 (48%), p=0.02. A logistic regression analysis was performed to identify AF recurrence predictors in the postoperative period. As a result, only widespread areas of low-amplitude activity were an independent predictor of AF recurrence after the pulmonary veins isolation, this predictive model was signiﬁcant (p=0.026). Signiﬁcant statistical diﬀerences between groups I, II and III,I V are the ejection fractions and the duration of the P-wave. Patients with low-voltage regions have lower left ventricular ejection fraction (62.8±6.9% versus 58.1±5.7%, p=0.01), and longer P-wave duration (84.7±8,2 ms versus 101.5±11.0 ms, p=0.01).Conclusion. LA high-density mapping before AF ablation makes it possible to determine the prevalence of low-voltage areas. After regression analysis, it was proved that common low-voltage areas are an independent predictor of AF recurrence after pulmonary vein isolation. Patients with low-voltage areas of more than 20% of the LA surface have longer P-wave duration and lower left ventricular ejection fraction.

Авторами статьи разработан унифицированный оголовок наблюдательной скважины месторождений питьевых подземных вод. Оголовок снабжен телеметрическими передающими станциями. Данное устройство испытали на наблюдательных скважинах водозабора «Авачинский» Елизовского месторождения питьевых подземных вод (Камчатский край). Результаты измерений температуры воздуха в скважине показали, что теплоизоляционный кожух предотвратил возникновение отрицательных температур внутри наземной части скважины. Это обеспечило надежное функционирование элементов питания телеметрической станции в осенне-зимний период. Защитный чехол в период испытаний обеспечил защиту теплоизоляции от воздействия ультрафиолетового излучения и влаги.
The authors of the article have developed a unified head of an observation well of drinking groundwater deposits, equipped with telemetric transmitting stations. This device was tested in the observation wells of the Avachinsky water intake of the Elizovski deposit of drinking groundwater (Kamchatka Krai). The results of measurements of the air temperature in the well showed that the thermal insulation casing prevented the occurrence of negative temperatures inside the ground part of the well thus providing for the reliable functioning of the power cells of the telemetry station in the autumn-winter period. A protective cover provided for the protection of the thermal insulation from the impact of ultraviolet radiation and moisture during the testing period.
Different helicity dependency of all-optical magnetization switching in GdFeCo films with optical interference layer
Authors: Yoshikawa Hiroki , Tajima Daiki , Kasatani Yuichi , Tsukamoto Arata 
Published: September 2022

Abstract
We observed helicity-dependent all-optical magnetization switching (HD-AOS) phenomena in GdFeCo films, which have equivalent magnetic properties but different optical properties due to optical interference layer thickness. Consequently, we found that these films have different properties of HD-AOS with the duality relation between magnetization direction and light helicity in light absorption, which generally means magnetic circular dichroism (MCD). Therefore, we also evaluated the effective absorption of the same GdFeCo samples which have similar intrinsic MCD by CW laser and intense femtosecond laser pulses. We confirmed that the contribution of this duality relation is much smaller in the absolute value of absorption. Furthermore, the magnitude and the sign of the duality relation change by the interference layer’s thickness. As a result, we concluded that the duality relation in HD-AOS is derived from the duality relation in absorption. Furthermore, its duality relation can be changed effectively using multiple interference effects.

Abstract
Silicon carbide (SiC) was coated onto carbon nanowall (CNW) scaffolds using chemical vapor deposition with a vinylsilane precursor at 700 °C to investigate the influence of the wall edge width, wall-to-wall distance, and surface morphology. The wall edge width ranged from 10 nm to those filling the wall-to-wall space without disrupting the CNW morphology. When SiC-coated CNWs (SiC/CNWs) were used as scaffolds for cell culture, cell viability increased until the edge area ratio reached 40%. In over 40% of edge area ratio, cell viability was saturate and comparable to flat surfaces such as SiC films on the Si substrate (SiC/Si) and control samples prepared using polystyrene. Calcification was suppressed in the CNWs, SiC/CNWs, and SiC/Si scaffolds compared to polystyrene. Our results suggest that SiC-coated CNW scaffolds could suppress calcification and promote cell proliferation.

Abstract
We study cobalt/platinum (Co/Pt) superlattices by means of ferromagnetic resonance spectroscopy in the frequency domain. The magnetization easy-axis of superlattices, which lies in a plane of the film with Co layers of 1.5 and 1.2 nm thickness, changes to the direction perpendicular to the film surface with Co layers of 0.9 and 0.6 nm thickness. As the Co layer thickness decreases from 0.9 to 0.6 nm, the Gilbert damping parameter significantly increases while the g-value is almost constant. As the Pt layer thickness decreases from 0.6 to 0.3 nm in the superlattices with 0.9 nm thick Co layers, the damping parameter slightly decreases. The present study demonstrates that the Co/Pt superlattices with 0.9 nm thick Co layers and 0.3 nm thick Pt layers are suitable for time-varying magnetic metamaterials realizing a larger magnetic permeability modulation.

DEGREE OF CORRECTION IN BUNION USING DYNAMIC SPLINTS
Authors: Rehman Zia , Shahid Osama 
Published: September 2022

Background. Hallux valgus or bunions the most widely recognized issue of the forefoot in grown-ups (1). The deformity of Hallux valgus is reformist, and includes a few phases, yet starts with lateral deviation of the big toe (Hallux) and medially deviation of the first main metatarsal bone. An Hallux valgus angle more prominent than 15 degrees is viewed as unusual yet at such a point the proximal phalanx may in any case be consistent with the metatarsal head when seen on radiographs.(2) The cause of Hallux valgus has been a discuss topic for years, but is likely associated with genetic predisposition, restrictive footwear, other foot deformities such as pronation of the hind foot furthermore, (pes planus, hyper mobility, contracture of the Achilles ligament , and neuromuscular problems, for example, cerebral paralysis and stroke(3). Orthoses have been proposed to lessen the raised plantar weight under the medial ray in patients with Hallux Valgus or bunion and diminish pain (7,8) when joined with a toe separator, orthosis may likewise assist with remedying alignment. Preventing general disability and halting the progression of structural changes are important for the management of hallux valgus. Objectives. To evaluate the clinical effects of dynamic splints on Hallux valgus this study was performed. To measure the degree of correction that can be achieved using the dynamic splints. Methods. Sample size was 8. Hallux valgus patients with age from 15-60 years, Mild, moderate Hallux Valgus, Hallux valgus angle < 40 degree, Both genders. Results. Total sample size was 8, in which 6 (75%) were Female and 2 (25%) were males, and they all are from Peshawar. Total sample size was 8 and Mean of the angle before using the splint is (20.75) and standard deviation among the angle was (2.315). Total sample size was 8 and Mean of the angle after using appliance for 15 day was (19.88) and standard deviation of the total population was (2.58), while the correction achieved in degree of angle has a mean of (1.00) and standard deviation of (0.535). Data was recorded and analyzed through SPSS. Conclusion. The persistence of the effect of orthosis is another point which could be assessed by evaluating changes during the wash-out period. The fact is that the angular changes are related to the time when orthosis is worn, so these changes were returned to first state by doffing the orthosis.
