Background: Following an early-stage cancer diagnosis, recurrences can occur. To quantify financial impacts of a first recurrence, we surveyed patients and caregivers.
Methods: The survey was self-administered online to patients ( = 202) with early-stage bladder, gastric, head and neck, melanoma, non-small cell lung, renal cell, and triple-negative breast cancers that recurred and caregivers ( = 100) of such patients.
Selective autophagy is an essential process to maintain cellular homeostasis through the constant recycling of damaged or superfluous components. Over a dozen selective autophagy pathways mediate the degradation of diverse cellular substrates, but whether these pathways can influence one another remains unknown. We address this question using pexophagy, the autophagic degradation of peroxisomes, as a model.

This anonymity provides acceptability to sexual and gendered minority youth (ages 16-24) at increased risk of HIV and other STIs with poor mental health due to higher levels of stigma, discrimination, and social isolation. This study evaluates the usability of Tabatha-YYC, a pilot chatbot navigator created to link these youth to mental health resources.

However, the mechanisms governing these processes in these different lysosomal organelles are poorly understood. Thus, the role of phosphatidylinositol-4-phosphate (PI(4)P) is unclear as it was shown to promote the formation of tubules from phagolysosomes but was proposed to inhibit tubule formation on autolysosomes because the loss of PI4KIIIβ causes extensive lysosomal tubulation.

Animals: 131 client-owned dogs surgically treated for naturally occurring unilateral or bilateral patella luxation between March 30, 2015, and February 12, 2020.
Procedures: Weight bearing as a percent body weight on each limb was recorded with the use of a platform device for analyzing stance (PetSafe Stance Analyzer; LiteCure LLC, Companion Animal Health) preoperatively and postoperatively for all dogs.
Purpose: We tested a novel dot survey methodology at our clinic that provides sexual health services to youth ages 13 to 24. We conducted two interactive dot surveys to assess their feasibility and acceptability while gaining insight into patients' attitudes about mental health.
Methods: We adapted a dot survey approach to assess youths' familiarity with mental health and attitudes toward related services.
The epidermal growth factor (EGF) receptor (EGFR) controls many aspects of cell physiology. EGF binding to EGFR elicits the membrane recruitment and activation of phosphatidylinositol-3-kinase, leading to Akt phosphorylation and activation. Concomitantly, EGFR is recruited to clathrin-coated pits (CCPs), eventually leading to receptor endocytosis.

Glycogen, by far the largest mammalian glucan and the largest molecule in the cytosol with up to 55 000 glucoses, does not, due to a highly regularly branched spherical structure that allows it to be perfused with cytosol. Aberrant construction of glycogen leads it to precipitate, accumulate into polyglucosan bodies that resemble plant starch amylopectin and cause disease.

Methods: This is a retrospective cohort study of women at increased risk of fetal aneuploidy and genetic disorders who had genetic counseling from January 2012 to December 2016 at a single academic center. Demographics, indications for genetic counseling, and rates of diagnostic testing were collected and compared between those who accepted diagnostic testing and those who chose cell free DNA.
Background: A complex system of factors interacting across time shapes community violence. It is not well understood how features of persons, institutions and communities interact as a "system" to produce escalating community violence. We aimed to integrate theoretical and experiential knowledge among young African-American urban males to develop a concept model of key causal structures driving dynamics of community violence escalation over time in a context of historical racism.

Although many interventions have been studied, 1 of the most effective treatments to decrease recurrent preterm birth is the use of weekly 17 alpha hydroxy progesterone caproate. Previous studies on the influence of excessive adipose tissue and obesity on the use of 17 alpha hydroxyprogesterone caproate for the prevention of recurrent spontaneous preterm deliveries have shown conflicting findings.

Membrane-bound organelles in eukaryotic cells form an interactive network to coordinate and facilitate cellular functions. The formation of close contacts, termed "membrane contact sites" (MCSs), represents an intriguing strategy for organelle interaction and coordinated interplay. Emerging research is rapidly revealing new details of MCSs.

BRCA 1/2 negative patients were contacted and offered MGPT. Patients completed pre- and posttest counseling, and surveys assessing cognitive, affective and behavioral outcomes at baseline, postdisclosure and 6 and 12 months.

Methods: Participants who received genetic research results answered open and closed-ended questions about their experiences receiving results and interest in and advantages and disadvantages of a web-based alternative to genetic counseling.
Results: 107 BRCA1/2 negative women with a personal or family history of breast cancer consented to receive genetic research results and 82% completed survey items about their experience.
Hepatic infarction is an exceedingly rare complication of hemolysis, elevated liver enzymes, and low platelets syndrome. Few cases have been described in the medical literature and the true incidence remains unknown. It can lead to fulminant liver failure, liver transplant, or death if not promptly addressed.

We have conducted a comprehensive literature review of the use of anticoagulation in pregnancy for pregnant women at increased risk for VTE. Multiple factors, including physiologic and pharmacokinetic changes make the treatment and prevention of VTE complicated in pregnancy.

Methods: A cross-sectional study was performed. BRCA1/2 mutation carriers with and without RRSO were surveyed to determine sexual function (Female Sex Function Index [FSFI]), demographics, medical history, sleep quality, depression, and anxiety scores.
Background: Premature cervical ripening plays a significant role in spontaneous preterm birth. Vaginal progesterone is the recommended treatment in singleton pregnancy with incidental short cervix. There is lack of evidence on whether it is beneficial to reinforce the cervix with cerclage when the cervical length becomes progressively shortened <10 mm while on vaginal progesterone.

Materials And Methods: -negative women with early-onset breast cancer, multiple primary cancers, or a family history of breast cancer who participated in a gene discovery cancer registry were offered the opportunity to learn their individual genetic research results of 24 breast cancer susceptibility genes with a genetic counselor after predisclosure genetic counseling. Outcomes included uptake of research results, knowledge, informed choice, psychosocial adjustment, uncertainty, satisfaction, and uptake of clinical confirmation testing.
Expanded genetic testing of BRCA mutations has led to identification of more reproductive-aged women who test positive for the mutation which might impact attitudes and decisions about relationships, childbearing and the use of preimplantation genetic diagnosis (PGD) and prenatal diagnosis (PND). A cross-sectional survey was administered to 1081 self-reported BRCA carriers to investigate how knowledge of BRCA status influences these issues. The mean age at BRCA test disclosure was 44 years and 36 % reported a personal history of cancer.

Guidelines are available for variant classification; however, interpretation of these guidelines by laboratories and providers may differ and lead to conflicting reporting and, potentially, to inappropriate medical management. We describe conflicting variant interpretations between Clinical Laboratory Improvement Amendments-approved commercial clinical laboratories, as reported to the Prospective Registry of Multiplex Testing (PROMPT), an online genetic registry.
View Article and Find Full Text PDFThe N17 domain of the huntingtin protein is post-translationally modified and is the master regulator of huntingtin intracellular localization. In Huntington's disease (HD), mutant huntingtin is hypo-phosphorylated at serines 13 and 16 within N17, and increasing N17 phosphorylation has been shown to be protective in HD mouse models. Thus, N17 phosphorylation is defined as a sub-target of huntingtin for potential therapeutic intervention.

Physical activity protects against breast cancer and one of the mechanisms which may underlie this association is exercise-induced changes in adipokine levels. The WISER Sister Trial was a three-armed randomized controlled trial in premenopausal women (n = 137) with an elevated risk for breast cancer.
