Using Voice-Activated Technologies to Enhance Well-Being of Older Adults in Long-Term Care Homes.

Background And Objectives: Information communication technologies (ICTs) can enhance older adults' health and well-being. Most research on the use of voice-activated ICTs by older adults has focused on the experiences of individuals living in the community, excluding those who live in long-term care homes. Given evidence of the potential benefits of such technologies to mitigate social isolation and loneliness, more research is needed about their impacts in long-term care home settings.

A Pilot Proteomic Study of Vestibular Fluid From Patients With Vulvodynia.

Objective: Many women are affected by vulvodynia, but medical therapies to date have proven ineffective. We performed a pilot study using gel-based proteomics to develop a map of proteins present in vaginal/vestibular secretions and identify proteins that could be considered for future evaluation as potential therapeutic targets.

Materials And Methods: We collected vestibular fluid from 4 controls and 4 patients with vulvodynia by placing a cotton swab in the vestibule and extracting the absorbed proteins.

Itraconazole Improves Vulvodynia in Fungus Culture-Negative Patients Post Fluconazole Failure.

Introduction: Vulvodynia is a difficult condition to treat due to both the uncertain etiology of the disorder and poorly available therapies. This difficulty leads to a disproportionately high prevalence and cost of treatment for this condition. Candida vulvovaginitis is a frequent co-present diagnosis in vulvodynia patients.

Leveraging digital tools to support recovery from substance use disorder during the COVID-19 pandemic response.

Treatment for substance use disorder (SUD) during the COVID-19 pandemic poses unique challenges, both due to direct effects from the illness, and indirect effects from the physical measures needed to "flatten the curve." Stress, isolation, lack of structure, limited access to physical and mental health care, and changes in treatment paradigms all increase risk of return to drug use events and pose barriers to recovery for people with SUDs. The pandemic has forced treatment providers and facilities to rapidly adapt to address these threats while redesigning their structure to accommodate physical distancing regulations.

Nova Scotia Needs Doctors: How Do We Attract and Keep Them?

Recruitment and retention of physicians, especially in rural communities, are severe public health policy problems in Canadian hospitals. This characterizes the situation in Nova Scotia. This study explored the Eastern Zone of the Nova Scotia Health Authority to determine ways to overcome the physician shortage.

Anti-Inflammatory Effect of Surfactant Lipid in the Vaginal Mucosa: A Pilot Study.

Objective: The aim of the study was to test the hypothesis that vaginal administration of surfactant lipids, which may counter-balance the proinflammatory effects of vaginal surfactant protein A, will decrease proinflammatory cytokines and increase anti-inflammatory cytokines in vaginal mucosal fluid in healthy women.

Materials And Methods: Three groups of healthy cycling women were randomized to receive vaginally a single dose of the following: (1) low-dose calfactant, a type of surfactant lipids, 0.8 mg/ml; (2) high-dose calfactant 8.

Eradicating group A streptococcus bacteria and biofilms using functionalised multi-wall carbon nanotubes.

Materials And Methods: Antibodies for GAS were covalently attached to carboxylated multi-wall carbon nanotubes and incubated with either planktonic or biofilm GAS. Bacterium was then exposed to 1.

Differential response of MCF7, MDA-MB-231, and MCF 10A cells to hyperthermia, silver nanoparticles and silver nanoparticle-induced photothermal therapy.

Purpose: Silver nanoparticles (Ag NP) can generate heat upon exposure to infrared light. The in vitro response of breast cell lines to Ag NP, both with and without nanoparticle-induced heating was evaluated.

Materials And Methods: Ag NP heat generation, intracellular silver concentration, and cell viability of MDA-MB-231, MCF7, and MCF 10A breast cells with Ag NP alone, or after exposure to 0.

A comparative study of the photothermal efficiency of electrically conducting poly(3,4-ethylenedioxythiophene)-based nanomaterials with cancer cells.

The photothermal efficiency of two similar organic nanomaterials, poly(3,4-ethylenedioxythiophene):poly(4-styrene-sulfonate) (PEDOT:PSS) nanoparticles and poly(3,4-ethylenedioxythiophene) (PEDOT) nanotubes, are compared. The PEDOT:PSS nanoparticles ranged from 100-200 nm in diameter, while the PEDOT nanotubes ranged from 200-400 nm in diameter and 4-10 microm in length. By changing the aspect ratio of the PEDOT nanomaterials from a spherical to a tubular shape, interesting differences in the optical and electronic properties of the materials were realized.

Low band gap donor-acceptor conjugated polymer nanoparticles and their NIR-mediated thermal ablation of cancer cells.

Low band gap D-A conjugated PNs consisting of 2-ethylhexyl cyclopentadithiophene co-polymerized with 2,1,3-benzothiadiazole (for nano-PCPDTBT) or 2,1,3-benzoselenadiazole (for nano-PCPDTBSe) have been developed. The PNs are stable in aqueous media and showed no significant toxicity up to 1 mg · mL(-1) . Upon exposure to 808 nm light, the PNs generated temperatures above 50 °C.

Cyclic changes in the level of the innate immune molecule, surfactant protein-a, and cytokines in vaginal fluid.

Problem: Our knowledge of the innate host defenses in the vagina, a site where these defenses are essential to protecting the host upper reproductive tract from invasion by pathogens, is as yet rudimentary. Specifically, little is known about the pattern-recognition component of vaginal innate immunity, the relationship of pattern-recognition molecules to known cytokine levels, and the role of gonadal hormones in their regulation.

Method Of Study: We measured levels of Surfactant Protein-A (SP-A), a prototypic innate pattern-recognition protein, in vaginal fluid (VF) and correlated them with levels of IL-1β and IL-8, two cytokines known to be present in VF.

A soluble high molecular weight copolymer of benzo[1,2-b:4,5-b']dithiophene and benzoxadiazole for efficient organic photovoltaics.

The synthesis and characterization of a soluble high molecular weight copolymer based on 4,8-bis(1-pentylhexyloxy)benzo[1,2-b:4,5-b']dithiophene and 2,1,3-benzoxadiazole is presented. High efficiency organic photovoltaic (OPV) devices comprised of this polymer and phenyl-C(71) -butyric acid methyl ester (PC(71) BM) were fabricated by additive processing with 1-chloronapthalene (CN). When the active layer is cast from pristine chlorobenzene (CB), power conversion efficiencies (PCEs) average 1.

Surfactant protein-A (SP-A) selectively inhibits prostaglandin F2alpha (PGF2alpha) production in term decidua: implications for the onset of labor.

Context: Labor is characterized by "decidual activation" with production of inflammatory mediators. Recent data suggest that surfactant protein-A (SP-A) may be critical to the onset of labor in mice. Whether this is also true in humans is unclear.

OCTN1 variant L503F is associated with familial and sporadic inflammatory bowel disease.

Purpose: A two-allele haplotype of TC (OCTN1 rs1050152 and OCTN2 -207G→C) is associated with Crohn's disease (CD). The association has been replicated in different populations, but also failed in some studies. The present study is to replicate the association of OCTN1 rs1050152 and examine another variant rs272879 with familial and sporadic inflammatory bowel disease (IBD) in a cohort from central Pennsylvania, USA.

Genetic association of DLG5 R30Q with familial and sporadic inflammatory bowel disease in men.

Background: The association of DLG5 R30Q with IBD has been replicated in several populations, but is not statistically significant in others. We studied the incidence of DLG5 alleles in a population of IBD patients from Pennsylvania.

Methods: DLG5 R30Q (rs1248696) and G1066G (rs1248634) were analyzed with PCR-based RFLP methods in a total of 521 subjects, that included 105 individuals with IBD and 139 without IBD from a familial IBD registry, 107 with sporadic IBD, and 170 unrelated healthy controls.

Genetic association of nonsynonymous variants of the IL23R with familial and sporadic inflammatory bowel disease in women.

Purpose: To replicate the association of IL23R R381Q (rs11209026) with inflammatory bowel disease (IBD), examine the effect of the two nonsynonymous variations, Q3H and L310P, on IBD, and to study gender distribution of these variants in IBD patients.

Results: IL23R R381Q was associated with Crohn's disease (CD) (P = 0.010), but not with ulcerative colitis (UC); L310P was associated with UC (P = 0.

Bis(μ-dithieno[3,2-b:2',3'-d]thio-phene-2,6-dicarboxyl-ato-κO:O)bis-[bis-(1,10-phenanthroline-κN,N')cobalt(II)] dimethyl-formamide disolvate.

The asymmetric unit of the title compound, [Co(2)(C(10)H(2)O(4)S(3))(2)(C(12)H(8)N(2))(4)]·2C(3)H(7)NO, contains one half of the formula unit, with the rest generated by inversion. The cobalt ion sits in a slightly distorted octa-hedral environment and is ligated to four N atoms of two 1,10-phenanthroline molecules and to two O atoms of two dithieno[3,2-b:2',3'-d]thio-phene-2,6-dicarb-oxy-l-ate anions. The anions act as bridges between the Co(II) centers.

Improvement in vulvar vestibulitis with montelukast.

Objective: To determine if montelukast treatment improves symptoms in patients with vulvar vestibulitis.

Study Design: We administered montelukast to a series of patients with vestibulitis seen at the Pennsylvania State University Vulvodynia Clinic over a period of 2.5 years.

Dyspareunia.

Dyspareunia, better termed women's sexual pain, is a poorly understood disorder once believed to be purely psychologic. Thanks to cooperative research efforts from several specialties toward defining subsets of the disorder, understanding the etiology of subsets and their comorbidities and new concepts for diagnosis and management are being validated or are being put into practice. This review describes the surprising prevalence of sexual pain, outlines new definitions for subtypes of sexual pain and diagnostic criteria for them, and applies these diagnoses to the task of selecting treatment options.

Preconceptional health: risks of adverse pregnancy outcomes by reproductive life stage in the Central Pennsylvania Women's Health Study (CePAWHS).

This study used population-based data to examine how health status and risks vary by reproductive life stage, with particular focus on the proximal risks for preterm birth and low birthweight (LBW) infants in preconceptional and interconceptional women. Data are from the Central Pennsylvania Women's Health Study (CePAWHS), which included a telephone survey of a representative sample of 2,002 women ages 18-45 years residing in largely rural central Pennsylvania. Women were classified according to reproductive stage--preconceptional, interconceptional, and postconceptional--on the basis of pregnancy history and reproductive capacity.

Surfactant protein A, an innate immune factor, is expressed in the vaginal mucosa and is present in vaginal lavage fluid.

Surfactant protein A (SP-A), first identified as a component of the lung surfactant system, is now recognized to be an important contributor to host defence mechanisms. SP-A can facilitate phagocytosis by opsonizing bacteria, fungi and viruses, stimulate the oxidative burst by phagocytes and modulate pro-inflammatory cytokine production by phagocytic cells. SP-A can also provide a link between innate and adaptive immune responses by promoting differentiation and chemotaxis of dendritic cells.

Clinical resistance of recurrent Candida albicans vulvovaginitis to fluconazole in the presence and absence of in vitro resistance.

Objective: To determine if failure of recurrent Candida albicans vulvovaginitis to respond clinically to fluconazole is related to in vitro mycologic resistance.

Study Design: We compared clinical response to fluconazole with culture and sensitivity data in all cases of recurrent C albicans vulvovaginitis referred to our clinic over an 18-month period.

Results: Of 52 patients referred to us with recurring vulvovaginitis, 10 were C albicans culture positive.

Recurrent vulvovaginal candidiasis.

Widespread use of over-the-counter antifungal medications has contributed to a large increase in the number of women who experience more than three episodes of candida vulvovaginitis per year. These women are particularly prone to chronic vulvovaginal pain syndromes; as such, the value of aggressive therapy based on detailed diagnosis extends well beyond immediate symptom relief. Diagnosis is complicated by the fact that a larger proportion of cases of are due to non-albicans species, which are not readily identifiable at office evaluation, and points to the value of fungal culture in such cases.

Modular regulation of cGATA-5 gene expression in the developing heart and gut.

The evolutionarily conserved GATA-5 transcription factor is an early and persistent marker of heart and gut development in diverse vertebrate species. To search for control regions that might regulate the chicken GATA-5 (cGATA-5) gene, we assayed a set of cGATA-5/lacZ constructs in transgenic mice and found evidence for two functionally conserved control regions that regulate different facets of cGATA-5 gene expression. The more distal control region is activated in embryonic endoderm at the head-fold stage, whereas the other control region contains a regulatory module that is activated in a restricted region of endoderm following closure of the gut tube.
