Assessment of the development of social skills among undergraduate medical students through participation in a socio-educational project during the coronavirus disease (COVID)-19 pandemic: a Brazilian pilot study.

Coronavirus disease (COVID)-19 had an impact on medical graduation, causing weaknesses arising from social isolation and remote emergency teaching, with an emphasis on deficits in the development of non-technical skills (soft skills). In this context, the interaction between a group of medical students and adolescents who develop activities at the Center for Learning and Mobilization for Citizenship in Campinas/SP, Brazil, was evaluated about the development of soft skills during the COVID-19 pandemic. The observational study was carried out using an electronic questionnaire based on a Likert scale on the feelings of undergraduate medical students regarding participation in project activities in the context of the development of social skills.

Community-Academic Partnerships for Health Research: An Iterative and Transparent Process of Patient Engagement Before the Research Begins.

Background: The root causes of coronavirus disease 2019 (COVID-19) disparities include longstanding systemic racial bias in economic advancement and care delivery, discrimination, lack of access, and social determinants of health. To address these causes, research institutions and health care systems must shift their lens from one that focuses solely on changing behaviors among underserved and vulnerable populations to one that is inward facing.

Methods: We worked with a community advisory board and an African American church that has partnered on research for more than a decade to identify community norms, needs, and key resources needed for establishing community-academic partnerships for COVID-19 testing.

Pragmatic design and inclusion of patient-partner representatives improves participant experience in clinical research.

Objectives: Patient engagement in the design and implementation of clinical trials is necessary to ensure that the research is relevant and responsive to patients. The PREP-IT trials, which include 2 pragmatic trials that evaluate different surgical preparation solutions in orthopaedic trauma patients, followed the patient-centered outcomes research (PCOR) methodology throughout the design, implementation, and conduct. We conducted a substudy within the PREP-IT trials to explore participants' experiences with trial participation.

Targeted Glioblastoma Treatment via Synthesis and Functionalization of Gold Nanoparticles With De Novo-Engineered Transferrin-Like Peptides: Protocol for a Novel Method.

Background: Glioblastoma multiforme (GBM) is an aggressive brain tumor with limited treatment options due to the blood-brain barrier's (BBB's) impedance and inherent resistance to chemotherapy. Gold nanoparticles (AuNPs) functionalized with transferrin-like peptides show promise in overcoming these challenges, enhancing drug delivery to the brain, and reducing chemotherapy resistance.

Objective: The primary goal of this study is to establish a detailed protocol for synthesizing and stabilizing AuNPs, functionalizing them with de novo-engineered transferrin-like peptides, and conjugating them with the chemotherapeutic agent temozolomide.

Developing patient-centered outcomes research infrastructure in a rural community through patient and stakeholder engagement and education during the COVID-19 pandemic.

In addition to facing numerous healthcare disparities, rural America is chronically underrepresented in clinical research. This gap was made more evident during the COVID-19 pandemic. St Lawrence Health, located in rural Upstate New York, established its Clinical and Rural Health Research Department in 2015 to help close this gap.

Epidemiological profile of dog attacks to patients under 14 years old assisted at the pediatric referral emergency unit of a tertiary hospital in Campinas, Brazil.

Introduction: Accidents involving dog attacks are very common, which makes this type of accident a global public health issue. The estimates point to 20% of the victims of such accidents seeking care in health units, and half of them being children. In addition to acute injuries, dog attacks might result in fractures, infections, scars, and psychological traumas.

Research in the USA on COVID-19's long-term effects: measures needed to ensure black, indigenous and Latinx communities are not left behind.

The SARS-CoV-2 (COVID-19) pandemic continues to expose underlying inequities in healthcare for black, indigenous and Latinx communities in the USA. The gaps in equitable care for communities of colour transcend the diagnosis, treatment and vaccinations related to COVID-19. We are experiencing a continued gap across racial and socioeconomic lines for those who suffer prolonged effects of COVID-19, also known as 'Long COVID-19'.

Storytelling training to promote stakeholder engagement in research dissemination.

Storytelling is increasingly recognized as a culturally relevant, human-centered strategy and has been linked to improvements in health knowledge, behavior, and outcomes. The Community Engagement Program of the Johns Hopkins Institute for Clinical and Translational Research designed and implemented a storytelling training program as a potentially versatile approach to promote stakeholder engagement. Data collected from multiple sources, including participant ratings, responses to open-ended questions, and field notes, consistently pointed to high-level satisfaction and acceptability of the program.

Pragmatic patient engagement in designing pragmatic oncology clinical trials.

Oncology trials are the cornerstone of effective and safe therapeutic discoveries. However, there is increasing demand for pragmatism and patient engagement in the design, implementation and dissemination of oncology trials. Many researchers are uncertain about making trials more practical and even less knowledgeable about how to meaningfully engage patients without compromising scientific rigor to meet regulatory requirements.

Implementing stakeholder engagement to explore alternative models of consent: An example from the PREP-IT trials.

Introduction: Cluster randomized crossover trials are often faced with a dilemma when selecting an optimal model of consent, as the traditional model of obtaining informed consent from participant's before initiating any trial related activities may not be suitable. We describe our experience of engaging patient advisors to identify an optimal model of consent for the PREP-IT trials. This paper also examines surrogate measures of success for the selected model of consent.

Nucleophilic Neutralization of Organophosphates: Lack of Selectivity or Plenty of Versatility?

Neutralization of organophosphates is an issue of public health and safety, involving agrochemicals and chemical warfare. A promising approach is the nucleophilic neutralization, scope of this review, which focuses on the molecular nucleophiles: hydroxide, imidazole derivatives, alpha nucleophiles, amines and other nucleophiles. A reactivity mapping is given correlating the pathways and reaction efficiency with structural dependence of the nucleophile (basicity) and the organophosphate (electrophilic centers, P=O/P=S shift, leaving and non-leaving group).

Patient and Provider Acceptability of a Patient Preauthorized Concealed Opioid Reduction.

Objective: Limited research of how to best taper opioids brings about an ethical and clinical dilemma. Experiments using overt and concealed administration of opioids have demonstrated the benefits of a concealed reduction to eliminate negative expectations and prolong analgesic benefits. This may allow for opioid tapering without significant increases in pain.

Supramolecular phosphate transfer catalysis by pillar[5]arene.

A kinetic study on dinitrophenylphosphate monoester hydrolysis in the presence of a cationic pillararene, P5A, has been carried out. Formation of the supramolecular complex between phosphate ester and P5A has been studied by NMR showing complexation-induced upfield proton shifts indicative of aromatic ring inclusion in the pillararene cavity. Molecular dynamic calculations allow structure characterization for the 1 : 1 and 1 : 2 complexes.

Randomized, double-blind, placebo-controlled, multicenter phase II study of the efficacy and safety of apricoxib in combination with either docetaxel or pemetrexed in patients with biomarker-selected non-small-cell lung cancer.

Purpose: Overexpression of COX-2 correlates with advanced stage and worse outcomes in non-small-cell lung cancer (NSCLC), possibly as a result of elevated levels of COX-2-dependent prostaglandin E2 (PGE2). Exploratory analyses of studies that used COX-2 inhibitors have demonstrated potentially superior outcome in patients in whom the urinary metabolite of PGE2 (PGE-M) is suppressed. We hypothesized that patients with disease defined by PGE-M suppression would benefit from the addition of apricoxib to second-line docetaxel or pemetrexed.

Chemotherapy dose reduction due to chemotherapy induced peripheral neuropathy in breast cancer patients receiving chemotherapy in the neoadjuvant or adjuvant settings: a single-center experience.

Purpose: Taxanes are a cornerstone treatment in early and advanced stage breast cancer and in other common solid tumor malignancies; however, the development of chemotherapy induced peripheral neuropathy (CIPN) often necessitates dose-reduction, which may hamper the effectiveness of the drug and compromise survival outcomes especially when used in the adjuvant setting. Limited literature is available on the prevalence and severity of dose reduction due to CIPN. We sought to determine the frequency and severity of CIPN-induced dose reduction in early stage breast cancer patients who received taxane-based chemotherapy in the neoadjuvant or adjuvant settings.

A pilot study of acupuncture in treating bortezomib-induced peripheral neuropathy in patients with multiple myeloma.

Background: Peripheral neuropathy is the dose limiting toxicity of bortezomib in patients with multiple myeloma (MM).

Objectives: To examine the safety, feasibility and efficacy of acupuncture in reducing bortezomib-induced peripheral neuropathy (BIPN) symptoms.

Methods: Patients with MM experiencing persistent BIPN ≥grade 2 despite adequate medical intervention and discontinuation of bortezomib received 10 acupuncture treatments for 10 weeks (2×/week for 2 weeks, 1×/week for 4 weeks, and then biweekly for 4 weeks).

Patient-reported outcomes in women with breast cancer enrolled in a dual-center, double-blind, randomized controlled trial assessing the effect of acupuncture in reducing aromatase inhibitor-induced musculoskeletal symptoms.

Background: Aromatase inhibitors (AIs) have been associated with decrements in patient-reported outcomes (PROs). The objective of this study was to assess whether real acupuncture (RA), compared with sham acupuncture (SA), improves PROs in patients with breast cancer who are receiving an adjuvant AI.

Methods: Postmenopausal women with a stage 0 through III breast cancer who received an AI and had treatment-associated musculoskeletal symptoms were randomized to receive 8 weekly RA versus SA in a dual-center, randomized controlled trial.

Major mechanistic differences between the reactions of hydroxylamine with phosphate di- and tri-esters.

Hydroxylamine reacts as an oxygen nucleophile, most likely via its ammonia oxide tautomer, towards both phosphate di- and triesters of 2-hydroxypyridine. But the reactions are very different. The product of the two-step reaction with the triester TPP is trapped by the NH2OH present in solution to generate diimide, identified from its expected disproportionation and trapping products.

A dual-center randomized controlled double blind trial assessing the effect of acupuncture in reducing musculoskeletal symptoms in breast cancer patients taking aromatase inhibitors.

Up to 50 % of women receiving aromatase inhibitor (AI) complain of AI-associated musculoskeletal symptoms (AIMSS) and 15 % discontinue treatment. We conducted a randomized, sham-controlled trial to evaluate whether acupuncture improves AIMSS and to explore potential mechanisms. Postmenopausal women with early stage breast cancer, experiencing AIMSS were randomized to eight weekly real or sham acupuncture sessions.

Intramolecular general base catalysis in the hydrolysis of a phosphate diester. Calculational guidance to a choice of mechanism.

Notwithstanding its half-life of 70 years at 25 °C, the spontaneous hydrolysis of the anion of di-2-pyridyl phosphate (DPP) is thousands of times faster (ca. 3000 at 100 °C, over 10000-fold at 25 °C) than expected for a diester with leaving groups of pK(a) 9.09.

Dephosphorylation reactions of mono-, di-, and triesters of 2,4-dinitrophenyl phosphate with deferoxamine and benzohydroxamic acid.

This work presents a detailed kinetic and mechanistic study of biologically interesting dephosphorylation reactions involving the exceptionally reactive nucleophilic group, hydroxamate. We compare results for hydroxamate groups anchored on the simple molecular backbone of benzohydroxamate (BHA) and on the more complex structure of the widely used drug, deferoxamine (DFO). BHA shows extraordinary reactivity toward the triester diethyl 2,4-dinitrophenyl phosphate (DEDNPP) and the diester ethyl 2,4-dinitrophenyl phosphate (EDNPP) but reacts very slowly with the monoester 2,4-dinitrophenyl phosphate (DNPP).

Domestic violence against children and adolescents: a challenge.

Objective: To study children and adolescents victims of domestic violence treated at the Referenced Pediatric Emergency Unit of the Hospital de Clínicas of the Universidade Estadual de Campinas and its specialized outpatient clinic between January 2003 and December 2007, emphasizing sexual abuse.

Methods: The variables gender, age, origin, and classification were studied. For victims of sexual abuse, the following variables were also studied: type of abuse (rape), location (domestic/urban), duration (acute/chronic), perpetrator (known, incestuous), alterations at medical examination, notification to child protection agencies, and antiretroviral medication and serology (HIV, syphilis, hepatitis B and C).

Activating water: important effects of non-leaving groups on the hydrolysis of phosphate triesters.

The high rate of spontaneous hydrolysis of tris-2-pyridyl phosphate (TPP) is explained by the activating effects of the non-leaving ("spectator") groups on P-OAr cleavage, and not by intramolecular catalysis. Previous work on phosphate-transfer reactions has concentrated on the contributions to reactivity of the nucleophile and the leaving group, but our results make clear that the effects of the non-leaving groups on phosphorus can be equally significant. Rate measurements for three series of phosphate triesters showed that sensitivities to the non-leaving groups are substantial for spontaneous hydrolysis reactions, although significantly smaller for reactions with good nucleophiles.
