RESUMEN

BACKGROUND: Respiratory syncytial virus (RSV) is a leading cause of acute respiratory illness (ARI) in older adults. Optimizing diagnosis could improve understanding of RSV burden. METHODS: We enrolled adults ≥50 years of age hospitalized with ARI and adults of any age hospitalized with congestive heart failure or chronic obstructive pulmonary disease exacerbations at two hospitals during two respiratory seasons (2018-2020). We collected nasopharyngeal (NP) and oropharyngeal (OP) swabs (n=1558), acute and convalescent sera (n=568), and expectorated sputum (n=153) from participants, and recorded standard-of-care (SOC) NP results (n=805). We measured RSV antibodies by two immunoassays and performed BioFire testing on respiratory specimens. RESULTS: Of 1,558 eligible participants, 92 (5.9%) tested positive for RSV by any diagnostic method. Combined NP/OP PCR yielded 58 positives, while separate NP and OP testing identified 11 additional positives (18.9% increase). Compared to Study NP/OP PCR alone, the addition of paired serology increased RSV detection by 42.9% (28 vs 40) among those with both specimen types, while the addition of SOC swab RT-PCR results increased RSV detection by 25.9% (47 vs 59). CONCLUSIONS: The addition of paired serology testing, SOC swab results, and separate testing of NP and OP swabs improved RSV diagnostic yield in hospitalized adults.

RESUMEN

Mango (Mangifera Indica L.) is a major tropical fruit rich in sugar, organic acids and flavonoids, making it suitable fruit for wine making. In the present study, five varieties of mango (Baganpalli, Langra, Dashehari, Alphonso, and Totapuri) were utilized for wine production using two different yeast strains namely, Saccharomyces cerevisiae MTCC 178 and isolated yeast. The physiochemical analysis of wine produced from chosen mango varieties showed that North Indian local mango variety (Dashehari) gave better results in terms of organoleptic and functional attributes. The Saccharomyces cerevisiae MTCC 178 treated Dashehari wine possessed 6.1 ± 0.26% TSS, 2.1 ± 0.08% reducing sugar, 0.657% titratable acidity, 0.11 ± 0.00% volatile acidity, 12% ethanol (v/v) and pH 3.7 ± 0.10 comparable to Baganpalli mango wine. HPLC analysis of Saccharomyces cerevisiae MTCC 178 inoculated Dashehari mango wine revealed the presence of primarily; gallic acid (RT-4.4 min), Galloyl-A-type, procyanidin (RT-5.2 min), 2,2,6-Trimethyl-6-vinyltetrahydropyran (RT-8.91 min), ß-Pinene (RT-11.47 min) and Caffeoyl-quinic acid (RT-12.15 min) showing potential antioxidant, anti-cancerous, anti-inflammatory and antimicrobial properties. The local mango varieties wine showed significant (p < 0.05) physicochemical properties, antioxidant potential and ethanol content comparable to Baganpalli wine and was cost effective.

RESUMEN

INTRODUCTION: Persistent bacterial infection prolongs hospitalizations, leading to increased healthcare costs. Treatment of these infections costs several billion dollars annually. Biofilm production is one mechanism by which bacteria become resistant. With the help of biofilms, bacteria withstand the host immune response and are much less susceptible to antibiotics. Currently, there is interest in the use of laser-generated shockwaves (LGS) to delaminate biofilm from infected wound surfaces; however, the safety of such an approach has not yet been established. Of particular concern are the thermal and mechanical effects of the shockwave treatment on the epidermis and the underlying collagen structure of the dermis. The present study is a preliminary investigation of the effect of LGS on freshly harvested ex vivo porcine skin tissue samples. MATERIALS AND METHODS: Tissue samples for investigation were harvested immediately post-mortem and treated with LGS within 30 minutes. Previous studies have shown that laser fluences between 100 and 500 mJ/pulse are capable of delaminating biofilms off a variety of surfaces, thus our preliminary investigation focused on this range of laser energy. For each sample, LGS were produced via laser irradiation of a thin layer (0.5 µm) of titanium sandwiched between a 50 and 100 µm thick layer of water glass and a 0.1 mm thick sheet of Mylar. The rapid thermal expansion of the irradiated titanium film generates a transient compressive wave that is coupled through a liquid layer to the surface of the ex vivo pigskin sample. Shocked samples were immediately fixed in formalin and prepared for histological analysis. A blinded pathologist evaluated and scored each section on the basis of its overall appearance (O) and presence of linear/slit-like spaces roughly parallel to the surface of the skin (S). The scores were given on a scale of 0-3. RESULTS: The present investigation revealed no visible difference between the tissue sections of the control sample and those that were subjected to laser-generated shockwaves. There was no relationship between the scores received by the samples and the energy with which they were shocked. CONCLUSION: Preliminary investigation into the safety of the LGS treatment for biofilm delamination appears promising. Additional investigation will continue on ex vivo porcine samples, followed by an in vivo animal trial to better understand the physiological response to LGS treatment.

RESUMEN

Acute urinary retention is a common clinical presentation in emergency departments in the UK and is responsible for over 30 000 hospital admissions annually. Awareness of the latest advice and guidelines regarding its presentation, investigation and management is paramount to improve patient outcomes and reduce morbidity. Immediate management of acute urinary retention relies on timely bladder decompression by catheterisation. Knowledge of the routes and types of catheterisation, including the associated risks, complications and contraindications, is essential to allow rapid and early intervention, thus preventing further complications. Differences in the presentation of patients with acute urinary retention reflect varying aetiologies, the knowledge of which determines long-term management and prognosis.

RESUMEN

BACKGROUND: Neuropsychiatric symptoms and CSF cytokine, chemokine, and SARS-COV-2 antibody profiles are unknown in pediatric patients with COVID-19 or multisystem inflammatory syndrome (MIS-C), (NP-COVID-19). METHODS: Children at a single pediatric institution quaternary referral center with laboratory-confirmed COVID-19 or MIS-C and neuropsychiatric symptoms were included in this retrospective case series. Clinical symptoms, ancillary testing data, treatments and outcomes are described. Multiplexed electrochemiluminescence assays for cytokines, chemokines and SARS-CoV-2 antibodies were tested in the CSF NP-COVID-19 patients compared to five controls and were analyzed using the Student's t-test. RESULTS: Three of five NP-COVID-19 patients had psychiatric symptoms, and two patients had encephalopathy and seizures. All patients had full or near resolution of neuropsychiatric symptoms by discharge. One patient received intravenous steroids for treatment for psychiatric symptoms; 3/5 other patients received immunotherapy for MIS-C, including IVIG, high-dose steroids, anakinra, and tocilizumab. Pro-inflammatory chemokines, including MIG, MPC, MIP-1ß, and TARC were significantly elevated in NP-COVID-19 patients compared to controls. Two of five patients had elevated CSF neurofilament light chain. CSF SARS-CoV-2 antibody titers to the full-length spike, receptor binding domain and N-terminal domain were significantly elevated. SARS-CoV-2 antibody titers strongly correlated with pro-inflammatory chemokines/cytokines, including IL-1ß, IL-2, IL-8, TNF-α, and IFN-γ (P≤0.05 for all). CONCLUSIONS: A spectrum of neuropsychiatric clinical manifestations can occur in children with SARS-CoV-2 infection. CSF pro-inflammatory chemokines and SARS-CoV-2 antibodies may serve as biomarkers of SARS-CoV-2 mediated NP-COVID-19. Additional study is required to understand the pathophysiologic mechanisms of neuroinflammation in children with COVID-19 and MIS-C.

RESUMEN

PURPOSE: Obesity is increasing in incidence in New Zealand. Maintaining locoregional control after breast cancer surgery is important, as this can improve overall survival. Although obesity has been associated with poorer survival in breast cancer, the correlation with locoregional control is less well evaluated and was the subject of this evaluation. METHODS AND MATERIALS: We used the New Zealand breast cancer registry to identify patients treated with breast conservation with body mass index (BMI) recorded. We retrieved patient demographic, tumor characteristic, and treatment-related information. We assessed local and locoregional control outcomes in addition to breast cancer and overall survival outcomes. RESULTS: Patients (2513) were identified. The median follow-up was 5.25 years. Of these patients, 38% were obese with a BMI of ≥30 kg/m2, 32% were overweight with a BMI of 25.0 to 29.9 kg/m2, and 29% were either normal or underweight with a BMI of ≤24.9 kg/m2. Most patients were postmenopausal (65%). The median tumor size was 16.0 mm (0.2-80 mm) and the majority were grade 2 or 3 tumors (45% and 33%). The majority (66%) were pathologically node negative and lymphovascular invasion was seen in 24%. There were 81% with estrogen receptor positivity and 358 (14.2%) were Her-2 positive. Local relapse free survival at 5 years was 91.5% (95% confidence interval [CI], 90.3-92.7) and at 10 years was 78.5% (95% CI, 75.9-81.1). Local relapse free rate at 5 years was 96.8% (95% CI, 96.0-97.6) and 10 years was 93.9% (95% CI, 92.5-95.3). We did not find BMI to be associated with local or locoregional relapse, disease free, breast cancer specific, or overall survival. CONCLUSIONS: Obesity was not associated with inferior locoregional control or survival outcomes. This supports the practice of continuing to offer breast conserving treatment to women regardless of BMI.

RESUMEN

There are ∼443 000 children in child protective custody (ie, foster care) in the United States. Children in protective custody have more medical, behavioral, and developmental problems that require health care services than the general population. These health problems are compounded by poor information exchange impeding care coordination. Health care providers often do not know which of their patients are in protective custody and are not privy to the critical social history collected by child protective services, including placement history and maltreatment history. Meanwhile, the custodial child protection agency and designated caregivers (ie, foster caregivers and kinship providers) often lack vital elements of the health history of children in their care, which can result in poor health care delivery such as medication lapses, immunization delay, and poor chronic disease management. In this case study, we address this critical component of health care delivery for a vulnerable population by describing a process of developing an information sharing system between health care and child welfare organizations in collaboration with child protection community partners. Lessons learned include recommended steps for improved information sharing: (1) develop shared community vision, (2) determine shareable information components, (3) implement and analyze information sharing approaches, and (4) evaluate information sharing efforts. A successful example of advocating for improvement of information sharing for youth in protective custody is explored to highlight these steps. In collaboration with child protective services, pediatricians can improve information sharing to impact both health care delivery and child protection outcomes.

RESUMEN

There are 427,000 children in protective custody in the United States. A lack of integration between the child welfare data system and electronic health record systems complicates the communication of critical health history details to caregivers. We created and evaluated automated ten custom algorithms linking these data. Deterministic matching was performed using combinations of first and last name, date of birth, and gender. If unmatched, a non-deterministic algorithm allowed for punctuation differences and letter transpositions. Of the children linked deterministically, 91.3% were linked. Of the ones undergoing non-deterministic matching, 71.3% were linked. Sharing integrated data is the first step in systematically improving health outcomes for children in protective custody. This approach represents an automatable and scalable solution that could help merge data from two disparate sources.

RESUMEN

BACKGROUND: Youth in protective custody (e.g.. foster care) are at higher risk for poorer physical and mental health outcomes compared with those who are not in custody. These differences may be due in part to the lack of research on the population to create evidence-based recommendations for health care delivery. A potential contributor to this lack of research is difficulties in obtaining informed consent for empirical studies in this population. The objective of this study was to describe the approaches to obtaining informed consent in minimal risk studies of foster youth and provide recommendations for future requirements. METHODS: We conducted a systematic review of the literature to characterize the informed consent approaches in published minimal risk research involving youth in foster care. We searched PubMed, CINAHL, PsychINFO, Embase, ERIC, Scopus, and EBMR. Inclusion criteria were: studies conducted in the United States, included current foster youth, minimal risk, peer reviewed, and published in English. Full text was reviewed, and individuals required to consent and assent were extracted. RESULTS: Forty-nine publications from 33 studies were identified. Studies required 0 to 3 individuals to consent. Individuals required to give consent included case workers (16, 48%), foster caregivers (12, 36%), biological parents (7, 21%), judges (5, 15%), and guardian ad litems (2, 6%). Twenty-nine (88%) studies required the youth's assent. The studies used 14 different combinations of individuals. One (3%) study utilized a waiver of consent. CONCLUSIONS: There is no consistent approach for obtaining informed consent for foster youth to participate in minimal risk research. Consent should ideally involve individuals with legal authority and knowledge of the individual youth's interests and should not be burdensome. Consensus regarding consent requirements may facilitate research involving foster youth.
