A system for local oscillator (LO) signal generation in 5G millimeter-wave (mmW) multi-antenna transceivers is presented. The system is modular with one phase locked loop (PLL) per antenna element transceiver, and a test circuit implemented in 28-nm fully depleted silicon on insulator (FD-SOI) CMOS features two such PLLs and a 491.52 MHz crystal oscillator (XO) generating a common frequency refere
Background: The Osborn or J-wave, an upright deflection of the J-point on the electrocardiogram (ECG), is often observed during severe hypothermia. A possible relation between Osborn waves (OW) and increased risk of ventricular arrhythmia has been reported. We sought to determine whether the level of targeted temperature management (TTM) following out-of-hospital cardiac arrest (OHCA) affects the
The first detailed chemical abundance analysis of the M-dwarf (M4.0) exoplanet-hosting star Ross 128 is presented here, based upon near-infrared (1.5-1.7 μm), high-resolution (R ∼ 22,500) spectra from the SDSS Apache Point Galactic Evolution Experiment survey. We determined precise atmospheric parameters T eff = 3231 ±100 K, log g = 4.96 ±0.11 dex and chemical abundances of eight elements (C, O, M
Objectives: To investigate the prevalence of obesity among different types of employment status in the Italian working population, and to examine associated risk factors. Material and Methods: Cross-sectional survey of 36 814 people that declared to have been occupied with the same type of contract for at least 5 years was analyzed. Multivariable logistic regression models were built considering w
Background: A varying response to cholinesterase inhibitor (ChEI) treatment has been reported among patients with Alzheimer’s disease (AD). Whether the individual-specific response directly affects time to nursing home placement (NHP) was not investigated. Objective: We examined the relationship between the 6-month response to ChEI and institutionalization. Methods: In a prospective, observational
Background: Treatment for cleft lip and/or palate (CL/P) involves a multidisciplinary team of experts who aim to improve ones’ appearance, health-related quality of life, and speech function. To appropriately measure outcomes in CL/P from the patient perspective, a CL/P-specific patient-reported outcome (PRO) instrument is needed. The CLEFT-Q is a self-report PRO instrument developed to evaluate t
Aim: This study compared follow-up protocols for paediatric celiac disease (CD) led by either paediatricians or dietitians at Swedish university hospitals. Methods: We followed 363 CD patients under 18 years at the university hospitals in Malmö (n = 140) and Lund (n = 79) between 2011 and 2013 and after they merged to become Skåne (n = 144) between 2014 and 2016. Both Lund and Malmö provided regul
The sustainability transformation calls for policies that consider the global consequences of local lifestyles. We used stakeholders' visions of sustainable lifestyles across Europe to build 19 scenarios of sufficiency (net reductions) and 17 of green consumption (shift in consumption patterns). We applied Environmentally Extended Multi-Regional Input-Output analysis to model scenarios by assuming
Background: Idiopathic ventricular fibrillation (IVF) is a rare cause of sudden cardiac arrest which may pose therapeutic and prognostic challenges. To date, the only effective treatment for survivors of cardiac arrest is the insertion of an implantable cardioverter-defibrillator (ICD). We sought to review the long-term outcome of a Swedish cohort with IVF. Methods and results: Fifty patients with
Background: Glomerulonephritis clusters in families. However, infections are common inducers of glomerulonephritis and may also cluster in families. Studies of adoptees and their biological and adoptive parents may disentangle genetic from environmental causes of familial clustering. This is the first adoption study aimed to estimate the genetic contribution to the familial transmission of glomeru
Purpose: Postresuscitation neuroprognostication is guided by neurophysiological tests, biomarker measurement, and clinical examination. Recent investigations suggest that circulating microRNAs (miRNA) may help in outcome prediction after cardiac arrest. We assessed the ability of miR-574-5p to predict neurological outcome after cardiac arrest, in a sex-specific manner. Methods: In this substudy of
Background: Incidence and long-term outcomes of choledochal malformations (CMs) in children remain unclear. Methods: Clinical characteristics, operative details, complications, and follow-up data were collected from eight pediatric surgical centers in Sweden, Norway, Denmark, and Finland, which also answered a questionnaire addressing management practices. Results: During 2000–2017, 126 pediatric
Lymphocytes from patients with insulin-dependent diabetes have been shown to be sensitized to pancreatic tissue antigens. Mice immunized with homologous pancreatic islets have been found to develop glucose intolerance and insulitis. Since lymphocytes may be involved in diabetogenesis, we wished to determine if lymph node cells from islet-immunized mice can recognize and respond to islet cells in v
Objective: To study the associations between serum testosterone and risk factors for atherosclerosis in 119 men from general population. Methods: Systolic pressure, body mass index (BMI), testosterone, fasting glucose, glucose tolerance test, apolipoprotein A-1 (ApoA-1), apolipoprotein B (ApoB), and ApoB/ApoA-1 ratio were assessed. Subjects classified into hypogonadal (testosterone ≤ 12 nmol/l), a
BACKGROUND: Surgical site infection (SSI) represents almost 40% of nosocomial infections. Risk for SSI is most prominent following colorectal surgery. There is no Swedish standard SSI classification or surveillance. We have failed to find validation of SSI surveillance programs presently in use. This study investigates SSI registration routines at Halmstad County Hospital, Sweden (HCH) as well as
In the struggle to reach the national environmental policy objectives, environmental compensation has emerged as a possible policy tool that may contribute to achieving the objectives. In Sweden, environmental compensation is legally mandated mainly in cases of exploitation within Natura 2000 areas and nature reserves, which is handled through the Swedish Environmental Code.

Background: A healthy lifestyle has been shown to reduce the risk of coronary artery disease (CAD). The extent to which lifestyle influences the risk of CAD for people with pre-existing non-modifiable risk factors is less studied. We therefore examined the associations between a favorable lifestyle and incidence of CAD in population subgroups based on gender, age, educational level, and parental h
