Globally, headache disorders are an important cause of disability in adults. As many types of headache (eg, migraine, tension-type and medication-overuse) are more common in women and have peak incidence in reproductive years, chronic headache disorders are highly prevalent in pregnant women. Some women with a history of migraine may find that it improves during pregnancy while others may find that their migraines become more unpredictable. Ideally, women with migraine and problematic headache disorder should be offered preconception counselling to address pregnancy-related concerns and advice on the use of medicines, which should be supported by high-quality information. For women with history of headache, the use of effective non-pharmacological options should be maximised, and the smallest number of the safest medicines at the lowest effective doses should be used while preparing for pregnancy and during pregnancy. This article forms part of the series of prescribing for pregnancy and discusses the impact of headache and migraine on pregnancy, the impact of pregnancy on headache and migraine and options for prophylaxis and treatment.Generic name RomosozumabBrand name EvenityFormulation 105 mg solution for injection in a pre-filled penMarket Authorisation holder UCB Pharma LimitedIndication treatment of severe osteoporosis in postmenopausal women at high risk of fractureDose 210 mg romosozumab (administered as two subcutaneous injections of 105 mg each) once a month for 12 months.

In this study, we aimed to identify BCRP substrates by an untargeted metabolomic approach. Mice were orally administered lapatinib to inhibit BCRP in vivo, and plasma samples were assessed by liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS), with all-ion fragmentation acquisition, and quantified by LC-MS/MS. A differential metabolomic analysis was also performed for plasma from Bcrp -/- and wild-type mice. Plasma peaks of food-derived isoflavone metabolites, daidzein sulfate (DS), and genistein sulfate (GS) increased after lapatinib administration and in Bcrp -/- mice. Administration of lapatinib and another BCRP inhibitor febuxostat increased the area under the plasma concentration-time curve (AUC) of DS, GS, and equol sulfate (ES) by 3.6- and 1.8-, 5.6- and ine by its inhibitors.Prior treatment with anti-PD-1 and/or BRAF-targeted therapies was associated with limited activity of tumor infiltrating lymphocytes (TIL) in metastatic melanoma. Recent insights into mechanisms of action for TIL and anti-PD-1 provide the foundation for understanding differences in outcomes in different trials or populations, and a roadmap for developing improved products.See related article by Seitter et al. p. XXXX.
Adoptive cell transfer (ACT) of autologous tumor-infiltrating lymphocytes (TIL) can mediate durable responses in patients with metastatic melanoma. This retrospective analysis provides long-term follow-up and describes the effect of prior therapy on outcomes after ACT-TIL.

Patients with metastatic melanoma underwent surgical resection of a tumor for generation of TILs and were treated with a lymphodepleting preparative regimen followed by adoptive transfer of TILs and intravenous IL2. Clinical characteristics of enrolled patients and treatment characteristics of TIL infusion products over two decades of ACT were analyzed to identify predictors of objective response.

Adoptive transfer of TILs mediated an objective response rate of 56% (108/192) and median melanoma-specific survival of 28.5 months in patients naïve to anti-programmed cell death-1 (PD-1) therapy compared with 24% (8/34) and 11.6 months in patients refractory to anti-PD-1 (aPD-1).

The biological mechanisms of work-related asthma induced by irritants remain unclear. We investigated the associations between occupational exposure to irritants and respiratory endotypes previously identified among never asthmatics (NA) and current asthmatics (CA) integrating clinical characteristics and biomarkers related to oxidative stress and inflammation.

We used cross-sectional data from 999 adults (mean 45 years old, 46% men) from the case-control and familial Epidemiological study on the Genetics and Environments of Asthma (EGEA) study. Five respiratory endotypes have been identified using a cluster-based approach NA1 (n=463) asymptomatic, NA2 (n=169) with respiratory symptoms, CA1 (n=50) with active treated adult-onset asthma, poor lung function, high blood neutrophil counts and high fluorescent oxidation products level, CA2 (n=203) with mild middle-age asthma, rhinitis and low immunoglobulin E level, and CA3 (n=114) with inactive/mild untreated allergic childhood-onset asthma.

To profile sleep duration and sleep efficiency in UK long-distance heavy goods vehicle (HGV) drivers and explore demographic, occupational and lifestyle predictors of sleep.

Cross-sectional analyses were carried out on 329 HGV drivers (98.5% men) recruited across an international logistics company within the midland's region, UK. Sleep duration and efficiency were assessed via wrist-worn accelerometry (GENEActiv) over 8 days. Proportions of drivers with short sleep duration (<6 hour/24 hours and <7 hour/24 hours) and inadequate sleep efficiency (<85%) were calculated. Demographic, occupational and lifestyle data were collected via questionnaires and device-based measures. Logistic regression assessed predictors of short sleep duration and inadequate sleep efficiency.

58% of drivers had a mean sleep duration of <6 hour/24 hours, 91% demonstrated <7-hour sleep/24 hours and 72% achieved <85% sleep efficiency. Sleeping <6 hour/24 hours was less likely in morning (OR 0.45, 95% CI 0.21 tohe road safety and public health implications.
Although small randomised controlled trials (RCTs) and observational studies have examined helmet non-invasive ventilation (NIV), uncertainty remains regarding its role. Selleckchem Linsitinib We conducted a systematic review and meta-analysis to examine the effect of helmet NIV compared to facemask NIV or high flow nasal cannula (HFNC) in acute respiratory failure.

We searched multiple databases to identify RCTs and observational studies reporting on at least one of mortality, intubation, ICU length of stay, NIV duration, complications, or comfort with NIV therapy. We assessed study risk of bias (ROB) using the Cochrane ROB tool for RCTs and the Ottawa-Newcastle scale for observational studies and rated certainty of pooled evidence using GRADE.

We separately pooled data from 16 RCTs (n=949) and 8 observational studies (n=396). Compared to facemask NIV, based on low certainty evidence, helmet NIV may reduce mortality (relative risk (RR) 0.56, 95% confidence interval (CI) (0.33 to 0.95)), and intubation (RR 0.35, 95% CI (0.22 to 0.56)) in both hypoxic and hypercapnic respiratory failure but may have no effect on duration of NIV. There was an uncertain effect of helmet on ICU length of stay and development of pressure sores. Data from observational studies was consistent with the foregoing findings but of lower certainty. Based on low and very low certainty data, helmet NIV may reduce intubation compared to HFNC, but its effect on mortality is uncertain.

Compared to facemask NIV, helmet NIV may reduce mortality and intubation; however, the effect of helmet compared to HFNC remains uncertain.

Numerous studies support the deleterious vascular impact of IH in rodents but an overall interpretation is challenging owing to heterogeneity in rodent species investigated and the severity and duration of IH exposure.To clarify this major issue, we conducted a systematic review and meta-analysis to quantify the impact of IH on systemic artery structure and function depending on the different IH exposure designs.We searched PubMed, Embase and Web of Sciences and included 125 articles in a meta-analysis, among them 112 using wild-type rodents and 13 using Apolipoprotein E knock-out mice. We used the standardised mean difference (SMD) to compare results between studies.IH significantly increased mean arterial pressure (+13.90 mmHg (95% CI [11.88; 15.92]), systolic and diastolic blood pressure. Meta-regressions showed that mean arterial pressure change was associated with strain and year of publication. IH altered vasodilation in males but not in females, and increased endothelin-1-induced, but not phenylephrine-induced, vasoconstriction. Intima-media thickness significantly increased upon IH exposure (SMD 1.10 [0.58; 1.62], absolute values +5.23 (2.81-7.84)). This increase was observed in mice but not in rats, and was negatively associated with age. Finally IH increased atherosclerotic plaque size in ApoE-/- mice (SMD 1.08 [0.80; 1.37]).To conclude, our meta-analysis established that IH, independently of other confounders, has a strong effect on vascular structure and physiology. Our findings support the interest of identifying and treating sleep apnea in routine cardiology practice.
Cystic Fibrosis (CF) is due to pathogenic variants in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene. Recent improvement enabled pharmacologic therapy aiming at restoring mutated CFTR expression and function. CFTR "modulators" have revolutionised the CF therapeutic landscape, particularly the last approved Trikafta. This drug-combination is indicated by FDA and very recently by EMA for genotypes carrying at least one copy of CFTR with F508del pathogenic variant. However, several genotypes, are not eligible for Trikafta treatment, yet.

We exploited an innovative cellular approach allowing highly efficient
-expansion of airway epithelial stem cells (AESC) through conditional reprogramming (CRC) from nasal brushing of CF patients. This approach, coupled to development of AESC-derived personalised disease models, as organoids and air liquid interface (ALI) cultures, revealed highly suitable for CFTR pharmacological-testing.

We fully validated the experimental models and implemented thdulators. Trikafta showed its efficacy also on three rare genotypes previously not eligible for modulators-treatment, opening the way to clinical translation. Finally, encouraging results for innovative drug combinations were also obtained.Rationale The objective was to assess the cost-effectiveness of staging positron emission tomography/computed tomography (PET/CT) in early-stage follicular lymphoma from the Canadian health care system perspective. Methods The study population was FL patients staged as early-stage using conventional CT imaging and planned for curative-intent radiation therapy (RT). A decision analytic model simulated the management after adding a staging PET/CT vs. using staging CT alone. In the no-PET/CT strategy, all patients proceeded to curative-intent RT as planned. In the PET/CT strategy, PET/CT information could result in an increased RT volume, switching to a non-curative approach, or no change in RT treatment as planned. Subsequent disease course was described using a state-transition cohort model over a 30-year time horizon. Diagnostic characteristics, probabilities, utilities and costs were derived from the literature. Baseline analysis was performed using quality-adjusted life years (QALYs), costs (2019 Canadian dollars, CAD$) and the incremental cost-effectiveness ratio.
