Osteogenesis imperfecta (OI), a heritable disorder caused by abnormalities in synthesis or processing of type I collagen, is characterized by skeletal fragility. Type I collagen interacts with multiple components of the extracellular matrix (ECM) including other collagens types. Thus, alterations in structure or quantity may broadly affect ECM homeostasis. In fact, while OI is clinically categorized by severity of bone disease, patients can also present with extra-skeletal manifestations, including the pulmonary, muscle and cardiovascular systems. Parathyroid hormone (PTH) is a regulator of skeletal homeostasis but the receptor for PTH/PTH1R is expressed in a variety of other tissues. Given interactions between type I collagen with other collagens in the ECM and the potential for PTH action on tissues beyond the skeleton, we explored whether serum levels of non-type I collagens are altered in response to teriparatide (human parathyroid hormone 1-34). We measured biomarkers of collagens II, III, IV, V, and VI in serum from individuals with type I and types III/IV OI in response to an 18 month course of teriparatide or placebo. These results were compared to similar biomarker measures in postmenopausal (PM) women without OI treated with teriparatide. In type I OI, teriparatide therapy increased concentrations of biomarkers of collagens II, III, IV, V, and VI. In individuals with types III/IV OI these biomarker changes in response to teriparatide were blunted, as we previously reported with collagen I biomarkers during teriparatide therapy. In contrast to OI, in PM women there were no effects of teriparatide on the collagen biomarkers we assessed (II, V, and VI). These findings suggest that in OI teriparatide therapy has abnormal effects on the homeostasis of many ECM collagens likely derived from skeletal as well as extra-skeletal tissues.

Conflicting results have been published regarding the effect of abnormal glucose metabolism on osteoporosis (AGM). Fasting glucose is a reliable indicator for abnormal glucose metabolism. Therefore, the aim of present study is to identify the association of fasting glucose level with the risk of incident osteoporosis.

In a cohort of 59,936 men and 36,690 women (mean age of 63.9±7.1years) registered in national health insurance database, we assessed the risk of incident osteoporosis according to the quartile levels of baseline fasting glucose (quartile 1 <88mg/dL, quartile 2 88-96mg/dL, quartile 3 97-107mg/dL and quartile 4 ≥108mg/dL) and glycemic status categorized into normal, impaired fasting glucose (IFG) and diabetes mellitus (DM). #link# Sacituzumabgovitecan -proportional hazard model was used in calculating adjusted hazard ratios (HRs) and 95% confidence interval (CI) for incident osteoporosis (adjusted HRs [95% CI]).

Compared with first quartile (reference), the risk of osteoporosis significantly decreasetly associated with the decreased risk of osteoporosis.

There is evidence that the extent of vertebral bone marrow adiposity increases caudally along the vertebral column in children and adolescents. However, no studies have examined the lipid composition of bone marrow along the vertebral column, which may uniquely influence bone acquisition and metabolism during growth independent of the amount of bone marrow adipose tissue. The goal of this study was to characterize the pattern of lipid composition index measures from the thoracic to lumbar spine (T11-L4) among a sample of adolescents with idiopathic scoliosis (AIS) undergoing routine orthopedic surgical care for scoliosis correction.

Adolescents between 14 and 18years of age, with a confirmed diagnosis of AIS, and undergoing routine posterior spinal fusion surgery at our institution were initially included for this descriptive study. The surgery yielded transpedicular vertebral body marrow samples from T11 through L4; 11 participants had bone marrow samples from T11 through L2 and 4 of the 11 participants e saturated (m=0.12; r=0.30; P=0.57) and monounsaturated (m=-0.68; r=0.74; P=0.09) indices, while the polyunsaturated index slope remained similar (m=0.56; r=0.89; P=0.02). Age, sex, height, body mass, and BMI were not associated with the pattern of any of the lipid composition index measures.

Study findings in this small sample of individuals with AIS suggest that the bone marrow saturated index may be relatively stable across T11-L4, while the monounsaturated index may decrease by 0.55-0.68% per vertebra and the polyunsaturated index may increase by 0.52-0.56% per vertebra in the caudal direction.

Dynamic high-intensity physical activity is thought to be beneficial for older adults' bone health. Traditional volume-based processing of accelerometer-measured physical activity data, quantified on a minute-per-minute basis, may average out sporadic high impact activity, whereas accelerometer data processing approaches based on identifying impacts can capture also these potentially beneficial short activity bursts. We investigated the associations between habitual physical activity and proximal femur bone traits among sedentary older adults utilizing three different numerical treatments of accelerometer-data to examine, if impact-based processing approaches are more suitable to assess bone loading than volume-based processing of physical activity data among older adults.

This cross-sectional study utilized the baseline data from the PASSWORD-study (n=284, mean±SD age 74±4years, 57% women). Total femur bone mineral content (BMC) and bone mineral density (BMD), femoral neck BMC, BMD, section modulus and mivity was positively associated with all bone traits (beta=0.147 to 0.182, p<0.001 to p=0.005) except MNW. Sedentary or moderate-to-vigorous activity, low, medium or high impacts or osteogenic index were not associated with any bone parameter.

Light physical activity may decelerate the age-related bone loss in older adults who do not meet the physical activity recommendations. link2 In this population, the amount of high impact activity may be insufficient to stimulate bone remodelling.

Liver function tests (LFT) abnormalities are reported in up to 50% of COVID-19 patients, and metabolic comorbidities are associated with poorer outcomes. The aim of the study was to determine the prevalence of liver steatosis and fibrosis in patients with COVID-19 and their association with clinical outcomes.

Retrospective study in hospitalized COVID-19 patients was conducted. The risk for liver steatosis was estimated by HSI > 36, and risk for advanced liver fibrosis with APRI > 1.0, NAFLD FS > 0.675 and/or FIB-4 > 3.25. Clinical outcomes were admission to Intensive Care Unit (ICU) and mortality.

Of 155 patients, 71.6% were male (n = 111), and 28.4% (n = 44) were obese. Abnormal LFT were present in 96.8% (n = 150), prevalence of steatosis was 42.6% (n = 66) and of significative liver fibrosis was 44.5% (n = 69). Liver fibrosis by FIB-4 was associated with risk of ICU admission (OR 1.74 [95%CI 1.74-2.68; p = 0.023]) and mortality (OR 6.45 [95%CI 2.01-20.83, p = 0.002]); no independent associations were found.

The prevalence of steatosis and significant liver fibrosis was high in COVID-19 patients but was not associated with clinical outcomes.

Do cumulative live birth rates (CLBRs) differ between women who have had a freeze-all embryo cycle (FAE) for endometrial fluid (EF) and controls?

This retrospective cohort study included 83 women who had a FAE cycle due to the presence of EF between 2010 and 2016 at a university-affiliated private IVF center. The controls were 219 women who had FAE for other indications during the same period and were randomly selected. The main outcome measures were CLBRs, EF recurrence, cancellation and pregnancy loss rates.

Population characteristics were comparable between the two groups. The CLBR was not significantly different between the EF and the control group 39.8 % vs. 47.0 %, respectively, p=0.26. Cancellation rates in the two first FETs were higher in the EF group than the control group 18.1 % vs. 4.1 % (p<0.001) and 22.9 % vs. 8.5 % (p=0.02). After FAE for EF, we observed a significant risk of EF recurrence (32/177 cycles, 18.1 %), allowing us to identify a poor prognosis subgroup. When EF was detected, the LBR per transfer was 7.1 % (1/14) when the transfer was finally performed (after EF aspiration or EF disappearance), compared to 25 % (32/128) in cycles without EF recurrence (p<0.05). link3 Conversely, in the absence of EF recurrence (145/177, 81.9 %), the LBR was comparable to that of the control group. The type of endometrial preparation does not seem to be associated with EF recurrence.

Despite higher rates of EF recurrence and cycle cancellation, women with FAE for EF ultimately have comparable LBRs to those who have had a FAE for other indications. However, women presenting with at least one EF recurrence during FETs seem to have a lower LBR.

The aim of the present study is to estimate the lifetime prevalence of suicidal ideation, plans, and attempts in a regional representative sample and the association of these outcomes with sociodemographic factors, prior mental disorders, and childhood adversities.

The PEGASUS-Murcia project is a cross-sectional survey of a representative sample of adults in Murcia that is part of the WHO World Mental Health Survey Initiative. The Composite International Diagnostic Interview (CIDI 3.0) was administered face-to-face to 2621 participants (67.4% response rate). The main outcomes were suicidal ideation, plans, and attempts. Lifetime prevalence, age of onset, and risk factors (sociodemographic variables, mental disorders, and childhood adversities) were examined using multiple discrete-time survival models.

Lifetime prevalence of suicidal ideation, plans and attempts were 8.0% (standard error, SE 1.1), 2.1% (SE 0.3), and 1.2% (SE 1.1), respectively. Prevalence of any childhood adversities was 22.1% (SE 1.3) in the total sample and, even higher, among those with suicide related outcomes (ranging between 36.8% and 53.7%). Female sex, younger age, prior (to onset of the outcome) lifetime prevalence of mood disorders, number of mental disorders, and exposure to childhood adversity were associated with significantly increased odds of suicidal ideation and plans.

Lifetime prevalence estimates of suicidality are similar to those in community epidemiological surveys. Childhood adversities and mental disorders, especially mood disorders, are important risk factors for suicidality. Early detection of these adversities and disorders should be targeted in suicide prevention programs.
