Assessing Residual Moisture After Sterilization as an Overlooked Source of Intraoperative Bacterial Contamination in Knee Intra-articular Reconstructions: Evaluating the Reliability of Routine Procedures and Tests.

Background: Contamination of sterilized surgical instruments is not a typically suspected source of increased infection rate, especially if no abnormalities in the sterilization process are detected.

Purpose/hypothesis: The purpose of this study was to report increased infection rates after knee ligament reconstructions due to undetectable sterilization process errors leading to residual moisture, not limited to a specific surgical tool. It was hypothesized that (1) residual moisture on surgical tools due to autoclave overloading would not be detected by autoclave self-diagnostics, chemical and biological tests, or organoleptic assessment and (2) this kind of contamination may elevate infection rates, especially in knee intra-articular reconstruction procedures.

Lateral femoral impaction fractures during an ACL tear extend posteriorly on the weight-bearing area of the tibiofemoral joint.

Purpose: Posterior elongation of the physiological terminal sulcus (TS) due to lateral femoral condyle impaction fracture (LFC-IF) after an anterior cruciate ligament (ACL) tear could potentially decrease the weight-bearing area of the tibiofemoral joint, decrease the tension on lateral meniscus and cause flattening of the LFC which would influence rotational knee motion and cause anisometry of the lateral and anterolateral stabilizers. Therefore, the purpose of the study was to assess if the LFC-IF elongates the physiological TS posteriorly.

Methods: One hundred patients magnetic resonance images (MRIs) (75 males, 25 females, mean age 32.

Genetic identification, morphology and distribution of subspecies in southern and western Switzerland (Reptilia, Squamata, Serpentes).

Most of Switzerland is inhabited by the nominotypical subspecies of the barred grass snake (), which is characterized by mitochondrial DNA lineage E. Only in the northeast of the country, the common grass snake () occurs and hybridizes with in a narrow contact zone. However, we discovered that in southern and western Switzerland barred grass snakes representing another mtDNA lineage (lineage C) are widely distributed.

Direct electrification of silicon microfluidics for electric field applications.

Microfluidic systems are widely used in fundamental research and industrial applications due to their unique behavior, enhanced control, and manipulation opportunities of liquids in constrained geometries. In micrometer-sized channels, electric fields are efficient mechanisms for manipulating liquids, leading to deflection, injection, poration or electrochemical modification of cells and droplets. While PDMS-based microfluidic devices are used due to their inexpensive fabrication, they are limited in terms of electrode integration.

Systematic literature review on surgical site preparation in paediatric surgery.

Background: Surgical site infections (SSIs) in children represent a common and serious postoperative complication. Surgical skin preparation is an essential preventive measure in every surgical procedure. The most commonly used antiseptic agents for surgical skin preparation are chlorhexidine gluconate and iodophors in alcohol-based solutions.

LuftiBus in the school (LUIS): a population-based study on respiratory health in schoolchildren.

Respiratory disease is common in children and strongly associated with lifestyle and environmental exposures. Thus, it is important to study the epidemiology locally. The LuftiBus in the School (LUIS) study was set up to assess the respiratory health of schoolchildren in the canton of Zurich, Switzerland.

"Linkage to care" among people living with HIV - definition in the era of "universal test and treat" in a sub-Sahara African setting.

Background: Prompt linkage to human immunodeficiency virus (HIV) care after diagnosis is of utmost importance for individual health and reduction of HIV transmission. Different definitions for “linkage to care” have challenged comparisons as a public health marker. Its meaning in the era of “universal test and treat” has transformed in all settings, but is most relevant in sub-Sahara Africa, where the burden of new HIV infection is still highest.

Links between biodiversity and human infectious and non-communicable diseases: a review.

Introduction: Biodiversity has intrinsic value and a fundamental role in human health. The relationship between them is complex, and the specific sustaining processes are still not well understood. In view of the rapidly evolving landscape, this literature review investigated scientific evidence for specific links between biodiversity and human infectious and non-communicable diseases to characterise identifiable relationships.

Bayesian networks to identify potential high-risk multimorbidity and intervention clusters in inpatients: an explorative data mining study.

Aims Of The Study: Based on large sets of routine hospital data from inpatient cases, we aimed to explore multimorbidity and intervention clusters showing high risks for in-hospital mortality and unplanned readmissions using data-driven analytical methods.

Methods: We performed an explorative, historical cohort study of consecutive inpatient cases at a tertiary care centre with an integrated platform for routine healthcare data in Switzerland. From January 2012 through to December 2017, all inpatients aged ≥18 years at hospital admission were eligible for study inclusion.

Identifying thresholds for classifying moderate-to-heavy soil-transmitted helminth intensity infections for FECPAKG2, McMaster, Mini-FLOTAC and qPCR.

The World Health Organization (WHO) has defined moderate-to-heavy intensity (M&HI) infections with soil-transmitted helminths (Ascaris lumbricoides, Trichuris trichiura and the two hookworms, Ancylostoma duodenale and Necator americanus) based on specific values of eggs per gram of stool, as measured by the Kato-Katz method. There are a variety of novel microscopy and DNA-based methods but it remains unclear whether applying current WHO thresholds on to these methods allows for a reliable classification of M&HI infections. We evaluated both WHO and method-specific thresholds for classifying the M&HI infections for novel microscopic (FECPAKG2, McMaster and Mini-FLOTAC) and DNA-based (qPCR) diagnostic methods.

Patterns of cross-sectional and predictive physical activity in Swiss adults aged 52+: results from the SAPALDIA cohort.

Background: Non-communicable diseases (NCDs) account for the vast majority of deaths in Switzerland. Insufficient physical activity (PA) is an established NCD risk factor and PA is known to be beneficial for physical and mental wellbeing. Sedentary behaviour (SB) is an additional, independent risk factor and associated with frailty in older adults.

Copeptin-based diagnosis of diabetes insipidus.

Polyuria-polydipsia syndrome consists of the three main entities: central or nephrogenic diabetes insipidus and primary polydipsia. Reliable distinction between these diagnoses is essential as treatment differs substantially, with the wrong treatment potentially leading to serious complications. Past diagnostic measures using the classical water deprivation test had several pitfalls and clinicians were often left with uncertainity concerning the diagnosis.

Reproductive number of the COVID-19 epidemic in Switzerland with a focus on the Cantons of Basel-Stadt and Basel-Landschaft.

The reproductive number in Switzerland was between 1.5 and 2 during the first third of March, and has consistently decreased to around 1. After the announcement of the latest strict measure on 20 March 2020, namely that gatherings of more than five people in public spaces are prohibited, the reproductive number dropped significantly below 1; the authors of this study estimate the reproductive number to be between 0.

Diagnoses made in an Emergency Department in rural sub-Saharan Africa.

Background: Information on diagnoses made in emergency departments situated in rural sub-Saharan Africa is scarce. The aim was: to evaluate the frequency of different diagnoses made in a new emergency department to define relevant healthcare requirements; and to find out if in-hospital mortality rates would decrease after the implementation of the emergency department.

Methods: In this observational study, we prospectively collated diagnoses of all patients presenting to the emergency department of the St Francis Referral Hospital in Ifakara, Tanzania during 1 year.

The Carabidae (Coleoptera) of Shada Al-A'Ala Nature Reserve, Southwestern Saudi Arabia, with description of a new species of Paussinae.

We report the Carabidae collected at the Shada Al-A'Ala Nature Reserve (SANR) in Baha Province in southwestern Saudi Arabia during 2013-2015. In total, 62 carabid species and subspecies representing 39 genera, 17 tribes, and 10 subfamilies were identified, including one new species, Nagel & Rasool, , four new country records, and 24 species that are new provincial records for Baha. The carabid fauna was dominated by the Lebiini with 19 species.

Health-seeking behaviour and treatment delay in patients with pulmonary tuberculosis in Switzerland: some slip through the net.

Aims Of The Study: To assess the health-seeking behaviour, the patient delay (onset of symptoms to first consultation) and the health system delay (first consultation to start of tuberculosis treatment) among patients with pulmonary tuberculosis (TB) diagnosed in Switzerland, and to assess the predictors of the various types of delay.

Methods: A survey among pulmonary TB patients was carried out in six cantons, covering 42% of all pulmonary adult TB cases notified in Switzerland. Data were collected by collaborators of the cantonal lung associations in charge of the follow-up of TB patients to investigate treatment seeking behaviour and to establish various delays and its predictors.

Overuse of antimicrobial prophylaxis in low-risk patients undergoing transurethral resection of the prostate.

Objective: To evaluate the current antimicrobial prophylaxis practices for low-risk patients undergoing transurethral resection of the prostate (TURP) or photoselective vaporisation of the prostate (PVP) in comparison with the antimicrobial prophylaxis recommendations of the European Association of Urology (EAU), which have been shown to effectively reduce infectious complications and antimicrobial resistance rates.

Methods: In May 2017, we sent an anonymous online -survey to board-certified urologists in Germany, Austria and Switzerland, by use of the database directory of the respective urology associations. Besides demographical questions, urologists were asked about their sources of information on antimicrobial prophylaxis prescription and their prescribing patterns before, during and after surgery in patients without an indwelling catheter or significant bacteriuria undergoing TURP or PVP.

Do late preterm twins face an increased neonatal morbidity compared with singletons?

Objective: Late preterm infants (born between 34 0/7 and 36 6/7 weeks of gestation) have been shown to have a higher morbidity and mortality than term infants. Furthermore, twins, both term and preterm, have a higher neonatal morbidity than singletons. The aim of our study was to examine if late preterm twins consequently have twice the neonatal morbidity when both risk factors prematurity and multiple pregnancy are present.
