The miR-101-3p/TBLR1 axis plays an important role in tumour ferroptosis. Nanopharmaceuticals that increase miR-101-3p levels may be effective therapies to inhibit tumour proliferation.

Despite the current trend towards less aggressive therapeutic approaches, acute haematogenous osteomyelitis (AHO) continues to be a challenge and is associated with significant morbidity worldwide. Our aim was to determine if 80% compliance with current protocol was achieved, identify complications and associated risk factors and analyse trends in aetiology and management of AHO in children.

We conducted a longitudinal, observational, single-centre study in patients with AHO aged less than 18 years admitted to a paediatric hospital, between 2008 and 2018, divided into 2 cohorts (before and after 2014). Demographic, clinical data and disease progression were analysed.

The study included 71 children with AHO, 56% male, with a median age of 3 years (interquartile range, 1-11). We found a 1.8-fold increase of cases in the last 5 years. The causative agent was identified in 37% of cases MSSA (54%), MRSA (4%), Streptococcus pyogenes (19%), Kingella kingae (12%), Streptococcus pneumoniae (8%), and Neisseria meningitidis (4%). Complications were identified in 45% of patients and sequelae in 3.6%. In recent years, there was an increase in myositis (30% vs. 7%; p=0.02), septic arthritis (68% vs. 37.2%; p=0.012) and in the proportion of patients treated for less than 4 weeks (37% vs. 3.5%; p=0.012), with a similar sequelae rates. The risk factors for complications were age 3 or more years, CRP levels of 20mg/l or higher, time elapsed between onset and admission of 5 or more days and positive culture, although on multivariate analysis only positive culture was significant. The presence of complications was a risk factor for sequelae at 6 months.

Our study confirms that AHO can be aggressive. The identification of risk factors for complications may be fundamental for management.

Tobacco-use among cancer survivors leads to preventable morbidity, mortality, and increased healthcare costs. We sought to explore the prevalence of smoking and e-cigarette use among survivors of tobacco and non-tobacco related cancers.

A cross-sectional analysis was conducted using the 2015-2018 National Health Interview Survey. Our primary outcome was the prevalence of current cigarette smoking or e-cigarette use among adults with self-reported history of tobacco related or non-tobacco related cancer. Logistic regression analysis was to assess the association of reported cancer type with cigarette smoking or e-cigarette use. https://www.selleckchem.com/ferroptosis.html Secondary outcomes included yearly trends and dual use.

A total of 12,984 respondents reported a history of cancer, representing a weighted estimate of 5,060,059 individuals with a history of tobacco-related malignancy and 17,583,788 with a history of a tobacco and non-tobacco related cancer, respectively. Survivors of tobacco-related cancers had a significantly higher prevalence ncers. There was a sequential increase in the prevalence of cigarette use during each subsequent year from the time of a new cancer diagnosis, underscoring the need for long term tobacco cessation support among newly diagnosed adults with cancer.

Older adults with metastatic renal cell carcinoma(mRCC) are underrepresented in immune-checkpoint inhibitor(ICI) registration trials. Here we compare the efficacy of ICI treatments in older vs. younger adults with mRCC.

Using the International mRCC Database Consortium(IMDC), patients treated with a PD(L)-1 based ICI were identified. Older adult was defined as ≥70-years at the time of treatment. Descriptive statistics were summarized in means, medians, and proportions. Effectiveness endpoints included overall survival (OS), time-to-treatment failure(TTF), time-to-next treatment(TNT), and overall response rate(ORR). Hazards ratios were adjusted(aHR) for IMDC risk factors, histology, line of treatment and older age.

Of 1427 included patients, 397(28%) were older adults. ICI was used as 1st line(1L) in 40%, 2nd line(2L) in 49% and 3rd line(3L) in 11% of patients. In univariable analysis, older adults had inferior OS compared to younger adults(25.1m vs. 30.8m, p<0.01). There were no significant differences in TTF (6.9m vs. 6.9m, p=0.4) or TNT(9.1m vs 10m, p=0.3) between groups. In multivariable analyses, older age was not independently associated with worse OS(aHR=1.02, p=0.8), TTF(aHR=0.95, p=0.6) or TNT(aHR=0.93, p=0.5). Older adults had a lower ORR compared to younger adults(24% vs. 31%, p=0.01), which was mainly driven by responses in 1L(31% vs. 44%, p=0.02) and not observed in 2L/3L.

After multivariable analyses, older adults with mRCC treated with ICI had no difference in OS, TTF or TNT when compared to younger adults. Our data support that chronological older age should not preclude patients from receiving ICI based therapies.

It has been postulated that the neurobiological mechanism responsible for the onset of symptoms of obsessive-compulsive disorder (OCD), especially compulsive behavior, is related to alterations of the goal-directed and habitual learning systems. However, little is known about whether changes in these learning systems co-occur with changes in the white matter structure of patients with OCD and their unaffected first-degree relatives (UFDRs).

Diffusion tensor imaging data were acquired from 32 patients with OCD (21 male), 32 UFDRs (16 male), and 32 healthy control subjects (16 male). White matter tracts in the goal-directed and habitual networks were reconstructed with seed-based probabilistic tractography. Partial least squares path modeling was used to measure the covariation between white matter connectivity, psychiatric symptoms, and cognitive flexibility.

Patients with OCD showed reduced connectivity in the fiber tracts within the goal-directed but not within the habitual network compared with healthy control subjects.
