RESUMO
PURPOSE: To examine state Area Agencies on Aging (AAAs) in Pennsylvania for services they provide to older adults regarding extreme events and how readiness can be captured through social networks and policies at the local, state, and federal levels. METHOD: Using an online survey, 79% of AAA directors answered questions describing perceptions and actions related to social capital and its influence on policy. RESULTS: AAAs acknowledged weather/temperature changes impact the need to prepare for common scenarios of extreme weather, temperature, and flooding. AAAs reported major social connections with county government and one state agency, with limited connections with federal agencies. CONCLUSION: Multiple opportunities exist for AAAs to consider climate change in expansion efforts, specifically regarding health care. Geriatric nurses can play a key role in expansion, advocacy, and policy development for AAAs that serve older adults in the context of climate change.

AIM: Skin conductance (SC) provides an objective measure of autonomic system regulation through sympathetic-mediated filling of sweat glands. This study aimed to test the utility of SC to detect sympathetic activation in neonatal abstinence syndrome (NAS). METHODS: Fourteen term (mean, SE: 38.8 ± 0.35 weeks gestational age) neonates with chronic prenatal opiate exposure were enrolled. SC (peaks/seconds and mean of peaks) was measured at baseline, during heel lance/squeeze (HLS) and recovery from HLS at 24-48 (mean 38) hours of life prior to treatment for NAS. Blinded coders with established reliability assessed neonates using the Modified Finnegan Neonatal Scoring System (MFNSS). Nonparametric tests were used to determine group differences, phase differences from baseline to HLS and HLS to recovery, and associations between MFNSS and SC measures. RESULTS: Neonates that would later require morphine treatment for NAS (n = 6) had higher baseline SC mean of peaks than those that did not require treatment (n = 8) (p < 0.05). Moreover, there were unique phase differences between groups and SC positively correlated with MFNSS (p < 0.05). CONCLUSION: SC provides early identification of NAS severity. However, a larger sample is needed to determine sensitivity and specificity of SC for early identification of NAS and treatment effectiveness.

Standards of care provided to volunteers in HIV prevention research in developing countries are evolving. Inconsistency in standards, particularly within a research network highlights the need to balance volunteers' health and wellness with the efficient conduct of research. Ten research centers (RC's) in East and Southern Africa affiliated with the International AIDS Vaccine Initiative (IAVI) were studied using a mixed methods approach to understand variations, similarities and gaps in services provided, recipients of services, referral systems, and barriers to referral uptake. These data were then used to develop expected standards across the 10 RCs. Findings indicated that RCs consistently provided HIV risk reduction and family planning (FP) counseling, male condoms, management of sexually transmitted infections, CD-4 counts, and general medical care to volunteers and non-research volunteers. Services that were less consistently provided on-site included: female condoms, adult male circumcision (AMC), antiretroviral therapy (ART) and post-exposure prophylaxis (PEP) in case of rape. The FP options provided on-site varied, with few providing implants, intrauterine devices, tubal ligation, and vasectomy. Most RCs had established referral systems for ART, AMC, PEP, and FP, but few had referral points for psychosocial services. Few RCs had comprehensive guidelines on referrals other than those related to adverse events. Findings indicate that the greatest challenges for referral uptake were transportation and health care costs, poor quality and inconsistency of services at some referral points. Few RCs covered the cost of referrals for non-study related adverse events. A collaborative process between IAVI and the RCs was undertaken to reach consensus on expected standards of care. A set of required and recommended services to be provided on-site or by referral was developed. In developing such standards, we tried to balance scientific priorities, equity, contextual realities, community expectations, and cost-effectiveness.

Given the ample evidence delirium in hospitalized older adults is underdiagnosed and not recognized by nurses up to 85% of the time, interventions are needed at the point of care to assist nurses in recognizing delirium. In this qualitative study, factors that might influence the implementation of a point-of-care screening tool for delirium were examined.

During the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, providing safe in-person schooling has been a dynamic process balancing evolving community disease burden, scientific information, and local regulatory requirements with the mandate for education. Considerations include the health risks of SARS-CoV-2 infection and its post-acute sequelae, the impact of remote learning or periods of quarantine on education and well-being of children, and the contribution of schools to viral circulation in the community. The risk for infections that may occur within schools is related to the incidence of SARS-CoV-2 infections within the local community. Thus, persistent suppression of viral circulation in the community through effective public health measures including vaccination is critical to in-person schooling. Evidence suggests that the likelihood of transmission of SARS-CoV-2 within schools can be minimized if mitigation strategies are rationally combined. This article reviews evidence-based approaches and practices for the continual operation of in-person schooling.

Quality improvement (QI) has been widely implemented in health services but has not been widely applied in HIV prevention research. Most prevention research centers have commonly employed traditional approaches (e.g., checklists) to quality control that document what has been done but not the quality of what has been done. Unlike other health settings, prevention research settings have unique characteristics and ethical requirements that require the development or adaptation of specific quality indicators. A QI model for health services was adapted for use in prevention research settings and was piloted between August 2006 and July 2007 at three research centers in East Africa. Four hundred and twenty-six volunteers exit interviews were administered in two cycles. Quantitative and qualitative data were analyzed using Excel worksheets. QI meeting reports and QI plans were used to complement data from exit interviews. On average, 52% of total enrolled volunteers participated in the exit interview. The designed QI plans successfully helped reduce volunteers' reported waiting time to see counselors (p<0.001) and pharmacists (p<0.001). It also increased the percentage of interviewed volunteers who reported being counseled on family planning at clinical trials (from 66 to 93%; p=0.02) at follow-up visits, and who were refreshed on informed consent at follow-up visits (from 90 to 96%; p=0.009). The percentage of interviewed volunteers that expressed satisfaction with services received from counselors increased (from 87 to 94%; p=0.009) while the percentage of volunteer satisfied with services from trial physicians remained constant (93%). The majority of volunteers interviewed reported satisfaction with other major components of research such as confidentiality, understanding of trial objectives, benefits and risks of participation, and risk reduction counseling. However, satisfaction with services from community outreach workers and other staff at research centers dropped over the course of the study (from 88% in Cycle 1 to 74% in Cycle 3; p= < 0.001). Increased commitment to QI is crucial in ensuring quality of services and ethical conduct of HIV prevention research centers.

Biologically active, nontherapeutic levels of pharmaceuticals have been detected in waterways and effluent. Although the vast majority of releases stem from human or animal excretion and production effluent, some come from disposal practices. Studies have demonstrated numerous links between environmental exposures from pharmaceutical compounds and their impact upon aquatic life. Nurses need to be aware of this issue since their roles in health care are expanding and considered among the most trusted. Throughout the life cycle of pharmaceuticals (design, approval/regulation, production, use, and discharge/disposal), nursing can play pivotal roles in reducing and eliminating pharmaceutical waste as well as improving public safety through decreasing poisoning and drug abuse. This article discusses the environmental impact of the pharmaceutical life cycle and what roles nurses have as clinicians, educators, advocates, and researchers.

BACKGROUND: Community participatory research encourages community involvement in early stages of program development and implementation, but sustainability is dependent on continued community interest and participation. While locally measured outcomes may not be generalizable, evaluations that demonstrate progress on community-specified markers of success can demonstrate a community's return on investment. The purpose of this study was to outline a process whereby community-identified indicators of successful violence prevention were translated into measurable variables. METHODS: Focus groups were conducted with key groups within identified neighborhoods experiencing high rates of violence in a large metropolitan area in the northeast United States. FINDINGS: From these groups, 40 indicators of successful violence prevention programs were expressed by the participants. Of these, 45 percent were matched to existing datasets with relevant variables. Datasets were then reviewed for accessibility. Feasibility of actually obtaining and analyzing data was tested by demonstrating the association between a "translated indicator" and a traditional indicator of violence. Greening data from Landsat satellite were correlated with shootings and mapped over target neighborhoods. CONCLUSIONS: Results indicate that it is possible to develop measurable community-specific indicators for evaluation of youth violence prevention programs and that these indicators have the potential for being generalizable across communities.

We performed multilocus sequence typing on 203 invasive disease isolates of Streptococcus pneumoniae to assess the clonal compositions of isolates from two provinces in Belgium and to determine the relationship between clones and antibiotic nonsusceptibility, particularly nonsusceptibility to two or more classes of antibiotics. The frequency of multiclass nonsusceptibility (MCNS) was higher in the province of West Flanders (38%) than in Limburg (21%). This difference was largely attributable to five clonal complexes (CC156, CC81, CC143, CC193, and CC1848), which contained high proportions of isolates with MCNS (>47%) and which were circulating at higher frequencies in West Flanders. The S. pneumoniae population changed over time, as CC156 and CC81 declined in frequency from 1997 to 1999 to 2001 to 2004. Over the same time period, the frequency of pneumococcal conjugate vaccine 7 (PCV7) serotypes dropped from 69% to 41%. In contrast, the nonvaccine serotype 19A increased in frequency from 2.1% to 6.6%. None of these changes can be attributed to PCV7 vaccine, as it was not in use in Belgium during the time period studied. There was evidence that MCNS clones flowed from West Flanders to Limburg.

Determining the genetic characteristics of Staphylococcus aureus is important for better understanding of the global and dynamic epidemiology of this organism as we witness the emergence and spread of virulent and antibiotic-resistant clones. We genotyped 292 S. aureus isolates (105 methicillin resistant and 187 methicillin susceptible) using a combination of pulsed-field gel electrophoresis, multilocus sequence typing, and SCCmec typing. In addition, S. aureus isolates were tested for the presence of the Panton-Valentine leukocidin (PVL) genes. Isolates were recovered from patients with uncomplicated skin infections in 10 different countries during five phase III global clinical trials of retapamulin, a new topical antibiotic agent. The most common methicillin-resistant clone had multilocus sequence type 8, pulsed-field type USA300, and SCCmec type IV and possessed the PVL genes. This clone was isolated exclusively in the United States. The most common PVL-positive, methicillin-susceptible clone had multilocus sequence type 121 and pulsed-field type USA1200. This clone was found primarily in South Africa and the Russian Federation. Other clones were found at lower frequencies and were limited in their geographic distribution. Overall, considerable genetic diversity was observed within multilocus sequence type clonal complexes and pulsed-field types.

The efficacy of beta-lactam antibiotics in Streptococcus pneumoniae has been compromised because of the development of altered penicillin-binding proteins (PBPs), however, this has been less so for amoxicillin than for penicillin. Recently, there have been a number of important methods developed to detect molecular adaptation in protein coding genes. The purpose of this study is to employ modern molecular selection approaches to predict sites under positive selection pressure in PBPs, derived from a large international S. pneumoniae collection of amoxicillin resistant and susceptible isolates, and encompassing a comparative data set of 354 pbp1a, 335 pbp2b, and 389 pbp2x gene sequences. A correspondence discriminant analysis (CDA) of positively selected pbp sites and amoxicillin MIC (minimum inhibitory concentration) values is then used to detect sites under positive selection pressure that are important in discriminating different amoxicillin MICs. Molecular adaptation was evident throughout PBP2X, with numerous positively selected sites in both the transpeptidase (TP) and C-terminal domains, strongly correlated with discriminating amoxicillin MICs. In the case of PBP1A positive selection was present in the glycosyltransfer (GT), TP and C-terminal domains. Sites within the TP domain tended to be correlated with the discrimination of low from intermediate MICs, whereas sites within the C-terminal tail, with a discrimination of intermediate from fully resistant. Most of the positively selected sites within PBP2B were in the N-terminal domain and were not correlated with amoxicillin MICs, however, several sites taken from the literature for the TP domain were strongly associated with discriminating high from intermediate level amoxicillin resistance. Many of the positively selected sites could be directly associated with functional inferences based on the crystal structures of these proteins. Our results suggest that clinical emphasis on TP domain sequences of these proteins may result in missing information relevant to antibiotic resistance development.

Evidence exists for both interspecific and intraspecific recombination (lateral gene transfer; LGT) involving Streptococcus pneumoniae pbp (penicillin binding protein) loci. LGT of capsular genes, or serotype switching, is also know to occur between S. pneumoniae of different serotype. It is not clear whether intraspecific pbp LGT is relatively common, whether there is a difference in the relative frequency of intraspecific LGT of different pbps, and whether serotype switching is more or less frequent than pbp LGT. The purpose of this study was to use comparative evolutionary biology analysis of 216 international clinical S. pneumoniae isolates, from the Alexander Project collection, to gain insight on these issues, as well as the possible role they might be playing in spreading amoxicillin resistance. All 216 isolates were genotyped using MLST and complete or nearly complete sequences for pbp1a, pbp2b, and pbp2x were determined. Amoxicillin MICs were available for each isolate. pbps were genotyped using phylogenetics and two or more pbp types within a MLST sequence type (ST) or clonal complex were taken as putative cases of pbp LGT; these hypotheses were statistically evaluated using the approximately unbiased (AU) test. Serotypes were determined for 171 of these isolates and the minimum number of switching events necessary to explain the serotype phenotypes for each of the STs and clonal complexes were evaluated. The majority (78%) of the amoxicillin resistant isolates were comprised in 5 clonal complexes. The relative frequency of pbp LGT was greatest for pbp2b and 2x (minimum of 10.2 and 7.8%, respectively, of the isolates consistent with the LGT hypothesis), followed by 1a (3.9%). Serotype switching was more frequent than intraspecific pbp LGT (33% of isolates consistent with serotype switching hypothesis). Although intraspecific LGT of pbps is occurring and has played a role in the spread of amoxicillin resistance in S. pneumoniae, clonal dissemination appears to be more significant.

OBJECTIVE: This study was undertaken to measure career satisfaction among obstetrics and gynecology residents and assess its relationship to burnout, depression, and malpractice concerns. STUDY DESIGN: A 63-item, anonymous, self-administered survey was distributed to residents at 23 randomly selected obstetric and gynecologic residency programs in the United States. The outcome measures included the Maslach Burnout Inventory-Human Services Survey, the Center for Epidemiological Studies-Depression Scale, and perceptions of malpractice and career satisfaction. RESULTS: Eighty-three percent of the residents were either "very or somewhat satisfied" with their career choice. The majority (89.8%) showed evidence of moderate burnout and 34.2% were considered depressed. Ninety-six percent were concerned about malpractice with 35% pursuing fellowship solely because of malpractice concerns. Residents dissatisfied with their career choice were twice as likely to be depressed (30% vs 55%, P = .03). Both emotional exhaustion (P < .0001) and consideration of fellowship because of malpractice (P < .0001) were strongly predictive of diminishing career satisfaction. CONCLUSION: Resident career satisfaction was inversely correlated with burnout and depression, which were more prevalent than expected. Overall, residents were satisfied with their career choice, but also negatively influenced by malpractice concerns.

PURPOSE: We wanted to analyze National Institutes of Health (NIH) awards to departments of family medicine. METHODS: We obtained the list of NIH awards to departments of family medicine in 2003, and collected additional information from the Internet regarding each principal investigator (PI), including whether he or she worked primarily in a core (central) organizational component within a family medicine department. RESULTS: One hundred forty-nine NIH awards were granted to 45 departments of family medicine, for a total of 60,085,000 dollars. Of 146 awards with a designated PI, approximately two thirds of awards (89, 61%) and awarded dollars (39,850,000 dollars, 70%) went to PIs who were either not full-time family medicine faculty primarily working in family medicine departments, or they were not working in core family medicine organizational components. Few awards to physician PIs in these non-core areas were to family physicians (4 of 37, 11%), whereas most awards to physician PIs in core family medicine areas went to family physicians (40 of 45, 89%). In contrast, most K awards (research career programs) went to PIs in core areas (19 of 23, 83%), and most to family physicians (17 of 23, 74%). Nationally, only 17 R01 awards (research project, traditional) went to family physicians. CONCLUSIONS: Most NIH awards to family medicine departments went to PIs in noncore organizational components, where most physician PIs were not family physicians. Family medicine departments interested in increasing NIH funding may want to consider 4 models that appear to exist: individual faculty in core departmental components, K awards, core faculty also working in university-wide organizational components that provide research infrastructure, and integrating noncore administrative components into the department.

Qualitative research was conducted in South Africa to determine perceptions about intra-vaginal microbicides in order to better understand the socioeconomic, cultural and structural contexts for the support of future introduction of this new HIV prevention method. Focus group discussions and in-depth interviews were conducted at community, health service, and policy levels of inquiry. The main study site was a black working class urban area close to Cape Town. "Desperation" in response to the HIV/AIDS epidemic, rape, sexual coercion and unplanned consensual sex emerged as major reasons to support microbicides, while concerns about the partial effectiveness of microbicide protection and its hypothetical nature elicited a more cautious approach. Other key findings included the likelihood that microbicides would be "mainstream", the possible impact on sexual practices and gender norms, issues of condom substitution/migration and potential avenues for education and distribution. We found that microbicides have the potential to meet diverse needs beyond that suggested by prior research. This included a desire for products that could protect against HIV infection following rape, sexual coercion and unplanned sex, and the finding that a wider range of people than previously suggested would potentially use microbicides. The challenge for microbicide introduction will be to develop products that can meet diverse needs not only in South Africa, but also in the broader global context.

PURPOSE: To report the effect of topically applied ketotifen fumarate in the treatment of superior limbic keratoconjunctivitis (SLK). METHODS: Five patients with clinical findings of bilateral SLK with no relief of symptoms with standard reported modalities of treatment were treated with topical ketotifen fumarate twice daily in both eyes. All patients were evaluated 2 to 4 weeks after initiation of treatment of symptomatic and clinical improvement and at regular intervals thereafter. RESULTS: Topical ketotifen provided immediate relief of ocular symptoms in all patients. In one patient, the response was long lasting, whereas in the other four, it was temporary, lasting 1 to 3 months. The objective signs, however, did not necessarily correlate with the subjective improvement. CONCLUSIONS: Ketotifen fumarate can be effective at least in the short to medium term in the management of SLK. Although the mechanism of action of ketotifen remains unclear, this preliminary experience further supports the use of agents with mast cell-stabilizing activity in the treatment of SLK.

The Laboratory System Improvement Program (L-SIP) of the Association of Public Health Laboratories aims to improve state public health laboratory (PHL) system performance through continuous quality improvement. We successfully applied this state assessment tool to a local PHL (LPHL) system by tailoring it to reflect local system needs and created an LPHL system definition explaining how a local system differs from, yet complements, a state system. On November 18, 2010, 75 stakeholders from 40 agencies assessed the Milwaukee, Wisconsin, PHL system, capturing themes, strengths and weaknesses of the system, and scores for each of the 10 Essential Public Health Services. A Laboratory Advisory Committee analyzed assessment results to identify a strategic focus of research and workforce development and define an action plan, which is now being carried out. Milwaukee's L-SIP process is effectively improving LPHL system research and workforce development while raising community awareness of the system.

Regulation of gene expression by microRNAs (miRNAs) is now considered as an essential mechanism for cell development and homeostasis. Indeed, numerous studies have reported that modulating their expression, maturation, or activity can affect cell survival, identity or activation. In particular, miRNAs are key players in the tight regulation of signaling cascades, and as such, they appear as perfectly suited immunomodulators. Several immune-related processes, including inflammation, have recently been demonstrated to require specific miRNAs. In addition, the discovery of herpesvirus-encoded miRNAs has reinforced this assumption. To decipher the potential roles of miRNAs in innate antiviral immune response, we developed an in vivo model based on the inoculation of mouse cytomegalovirus (MCMV) in mice. Furthermore, we exploited a mouse line carrying a hypomorphic mutation in the Dicer gene to visualize the impact of impaired miRNA biogenesis upon the anti-MCMV response. Our data indicate that miRNAs are important actors in mounting an efficient response against herpesviruses. We suggest that a rapid and transient interferon response following viral infection requires miRNA-dependent repressor release. In addition, our in vivo efforts identified several miRNA targets, thus providing a conceptual framework for future analyzes on the regulation of specific actors involved in the Type I interferon pathway.
