RESUMO

INTRODUCTION: Acne vulgaris is a common skin disease prevalent in skin of color patients. Studies have demonstrated that dapsone gel, 7.5% (Aczone) used once daily is effective, safe, and well-tolerated for the treatment of acne in both men and women. However, minimal data are available in skin of color populations. This single-center, open-label clinical study investigated the efficacy and safety of dapsone gel, 7.5% in the treatment of moderate to severe acne vulgaris in patients with Fitzpatrick skin types IV-VI. METHODS: Twenty (20) adult subjects with moderate to severe acne and Fitzpatrick skin types IV-VI were enrolled in this study and treated with dapsone gel, 7.5% once daily for 24 weeks. RESULTS: Dapsone gel, 7.5% applied daily for 24 weeks reduced acne severity, post-inflammatory hyperpigmentation, and decreased new inflammatory and noninflammatory acne lesions in skin of color patients with moderate to severe acne vulgaris. Treatment resulted in improved acne health-related quality of life and patient symptoms related to acne, including patient-reported post-inflammatory hyperpigmentation, especially with a treatment duration of 18 weeks or longer.  Limitations: The sample size was small and underpowered to detect statistically significant changes in some endpoints. CONCLUSION: Dapsone gel 7.5% was safe, well-tolerated, and efficacious in treating acne vulgaris and post-inflammatory hyperpigmentation in skin-of-color patients. Larger studies involving skin-of-color populations with acne vulgaris are warranted. J Drugs Dermatol. 2024;23(6):410-417. doi:10.36849/JDD.7897.

RESUMO

BACKGROUND: There is a paucity of data on the treatment of psoriasis in patients with skin of color – a diverse population among whom variations in clinical features and higher quality of life impact have been reported. This single-center, open-label clinical study evaluated the safety and efficacy of secukinumab in the treatment of moderate-to-severe plaque psoriasis in adults with Fitzpatrick skin types IV-VI. METHODS: A total of 20 male and female subjects (ages ≥ 18, BSA ≥10%, PASI Score ≥ 12, IGA ≥ 3) completed this study. The total study duration was 28 weeks. During the treatment period, subjects received secukinumab 300 mg subcutaneously at weeks 0, 1, 2, 3, and 4, then monthly through week 20. RESULTS: 73% of patients achieved at least 90% improvement in PASI score (PASI90) at week 16 compared to baseline (P=0.0592). There was a statistically significant proportion of patients achieving PASI75, IGA of clear or almost clear, and a change from baseline in DLQI total score at weeks 12, 16, and 24. A statistically significant reduction in IGAxBSA-75 score was achieved between week 16 and baseline. LIMITATIONS: The sample size was small and underpowered to detect statistically significant changes in some endpoints. Furthermore, the study period was interrupted by the COVID-19 pandemic, which contributed to numerous missing data points. CONCLUSION: Secukinumab 300 mg administered monthly was safe, well-tolerated, and efficacious in treating skin of color patients with psoriasis and improving health-related quality of life. Larger studies involving skin of color populations with psoriasis are warranted. J Drugs Dermatol. 2024;23(8):600-606. doi:10.36849/JDD.8128.

RESUMO

BACKGROUND: There is a paucity of data on usage of topical medications in patients with darker phototypes. This single-center, randomized, double-blinded, vehicle-controlled clinical study investigated the efficacy of a combination calcipotriene/betamethasone dipropionate (Cal/BD) aerosol foam 0.005%/0.064% in the treatment of psoriasis vulgaris in Fitzpatrick skin types IV to VI. METHODS: 25 adult subjects were randomized 4:1 to Cal/BD foam or foam vehicle once daily for 4 weeks followed by 4 weeks of open label treatment. From week 4 to week 8, subjects randomized to Cal/BD foam once daily switched to Cal/BD foam twice weekly for 4 weeks, while those randomized to vehicle applied Cal/BD foam once daily. RESULTS: At week 4, 4/19 (21%) of Cal/BD foam patients achieved clear/almost clear Investigator Global Assessment (IGA) status with ≥2 grade improvement compared with 0/5 (0%) of vehicle patients (P=0.54). 12/19 (63%) of Cal/BD foam patients achieved a 50% reduction in Psoriasis Area and Severity Index (PASI 50) at week 4, compared with 0/5 (0%) of vehicle patients (P=0.04). Mean changes in melanin index at week 4 indicate a trend toward increased pigmentation in Cal/BD foam patients and decreased pigmentation in foam vehicle patients (P=0.30). All adverse events were mild and deemed unrelated to treatment by the investigators. LIMITATIONS: The sample size was small and underpowered to detect statistically significant changes in most endpoints. CONCLUSION: Cal/BD foam was safe and well tolerated in plaque psoriasis patients with skin of color. Larger studies involving skin of color populations with psoriasis are warranted. Pigmentary changes (hyper- and hypopigmentation) in lesional skin were observed. J Drugs Dermatol. 2023;22(2): 165-173.doi:10.36849/JDD.6910.

RESUMO

OBJECTIVE: In 2007, Congress changed the military's sexual assault laws as part of an effort to improve sexual assault case processing. This study looked at the U.S. Army law enforcement investigative finding for every sexual assault reported to the Army from 2004 through June 2012, along with every nonsexual assault. Our objective was to measure whether the legal intervention affected the investigative findings made by Army law enforcement officers in sexual assault cases (penetrative, nonpenetrative, and combined) as compared to assault cases (aggravated, simple, and combined). HYPOTHESES: We hypothesized that we would not find evidence that the legal intervention affected the rate of sexual assault cases labeled as "founded" by Army law enforcement, such that for the best-fitting time-series models, any difference in the residuals of the means before and after the intervention would not be statistically significant. METHOD: We received data from the U.S. Army on all sexual assaults and nonsexual assaults from 2004 through June 2012. The data comprised 47,058 observations. We used time-series analysis with autoregressive integrated moving average modeling. The variable tracked over time was the ratio of the proportion of founded sexual assault cases to the proportion of founded nonsexual assault cases. We then conducted t tests of the means of the residuals before and after the legal intervention. RESULTS: The difference in the means of the residuals before and after the intervention was not statistically significant for combined sexual assaults versus combined assaults, penetrative sexual assaults versus aggravated assaults, or nonpenetrative sexual assaults versus simple assaults. CONCLUSIONS: This reform to sexual assault laws does not appear to have affected sexual assault case processing by U.S. Army law enforcement.

RESUMO

Hurricane Sandy was the greatest natural disaster to ever impact public housing residents in New York City. It affected approximately 80,000 residents in 400 buildings in 33 developments throughout the city. The storm left residents without power, heat, or running water, yet many chose not to evacuate. This qualitative study was conducted to understand the impact of Sandy among this socially, physically, and geographically vulnerable population. It is the first known study to examine the impact of disasters in high-rise, high-density public housing as a unique risk environment. Findings demonstrate (1) broad impacts to homes, health and access to resources, (2) complex evacuation decision-making, (3) varied sources of support in the response and recovery phases, and (4) lessons learned in preparedness. Results are contextualized within an original conceptual framework-"resilience reserve"-that explains the phenomenon of delayed recovery stemming from enactments of resilience to manage chronic hardship leaving vulnerable populations without the requisite capacity to take protective action when facing acute adversity. We discuss recommendations to establish and replenish the resilience reserve that include personal, institutional, and structural facets.

RESUMO

A novel series of ferrocenyl chalcone ammonium and pyridinium salt derivatives were synthesized in order to improve their solubility in aqueous media. Substituted ferrocenyl chalcones with amines and pyridines were synthesized using the base-catalyzed Claisen-Schmidt reaction, and their corresponding salts were prepared by a nucleophilic quaternization reaction at the nitrogen atom. Most of the synthesized ferrocenyl chalcone salts were soluble in water at room temperature. They were fully characterized by IR, NMR spectroscopy and HRMS spectrometry, and their electrochemistry was studied. The salt derivatives presented chemical reversibility, electrochemical quasi reversibility, and the slope of a plot of Log Ipc (or Ipa) versus Log v were almost 0.5 suggesting that their redox process was controlled by diffusion.

RESUMO

BACKGROUND & AIMS: The 2015 American Gastroenterological Association guidelines recommend discontinuation of surveillance of pancreatic cysts after 5 years, although there are limited data to support this recommendation. We aimed to determine the rate of pancreatic cancer development from neoplastic pancreatic cysts after 5 years of surveillance. METHODS: We performed a retrospective multicenter study, collecting data from 310 patients with asymptomatic suspected neoplastic pancreatic cysts, identified by endoscopic ultrasound from January 2002 to June 2010 at 4 medical centers in California. All patients were followed up for 5 years or more (median, 87 mo; range, 60-189 mo). Data were used to calculate the risk for pancreatic cancer and all-cause mortality. RESULTS: Three patients (1%) developed invasive pancreatic adenocarcinoma. Based on American Gastroenterological Association high-risk features (cyst size > 3 cm, dilated pancreatic duct, mural nodule), risks for cancer were 0%, 1%, and 15% for patients with 0, 1, or 2 high-risk features, respectively. Mortality from nonpancreatic causes was 8-fold higher than mortality from pancreatic cancer after more than 5 years of surveillance. CONCLUSIONS: There is a very low risk of malignant transformation of asymptomatic neoplastic pancreatic cysts after 5 years. Patients with pancreatic lesions and 0 or 1 high-risk feature have a less than 1% risk of developing pancreatic cancer, therefore discontinuation of surveillance can be considered for select patients. Patients with neoplastic pancreatic cysts with 2 high-risk features have a 15% risk of subsequent pancreatic cancer, therefore surgery or continued surveillance should be considered.

RESUMO

BACKGROUND: The majority of branch duct intraductal papillary mucinous neoplasms (BD-IPMNs) are recommended for surveillance imaging based on consensus guidelines. However, growth rates that should prompt concern for malignant transformation of BD-IPMN are unknown. AIMS: To determine whether BD-IPMN growth can predict an increased risk of malignancy and define growth rates concerning for malignant BD-IPMN. METHODS: The study is a retrospective, multicenter study of suspected BD-IPMN patients undergoing imaging surveillance. All patients underwent EUS evaluation followed by surveillance imaging. RESULTS: Two hundred and eighty-four patients with suspected BD-IPMN without worrisome features or high-risk stigmata were followed for a median 56 months and underwent a median of four imaging studies. Nine patients (3.2 %) developed malignant BD-IPMN. Malignant BD-IPMN grew at a faster rate (18.6 vs. 0.8 mm/year; P = 0.05) compared to benign BD-IPMN. BD-IPMN growth rate between 2 and 5 mm/year was associated with an increased risk of malignancy with hazard ratio (HR) of 11.4 (95 % CI 2.2-58.6) when compared to subjects with BD-IPMN growth rate <2 mm/year (P = 0.004). BD-IPMN growth rate ≥5 mm/year had a hazard ratio of 19.5 (95 % CI 2.4-157.8) (P = 0.005). BD-IPMN growth rate of 2 mm/year had a sensitivity of 78 %, specificity of 90 %, and accuracy of 88 % to identify malignancy. Total BD-IPMN growth was also associated with increased risk of malignancy (P = 0.003) with all malignant IPMNs growing at least 10 mm prior to cancer diagnosis. CONCLUSIONS: BD-IPMN growth rates ≥2 mm/year and total growth of ≥10 mm should be considered worrisome features for BD-IPMN at increased risk of malignancy.

RESUMO

BACKGROUND: The current social and political context is generating socio-economic inequalities between and within countries, causing and widening health inequalities. The development and implementation of interventions in primary health care (PHC) settings seem unavoidable. Attempts have been made to draw up adequate criteria to guide and evaluate interventions but none for the specific case of PHC. This methodological article aims to contribute to this field by developing and testing a set of criteria for guiding and evaluating real-life interventions to reduce health inequalities in PHC settings in European regions. METHODS: A literature review, nominal group technique, survey and evaluation template were used to design and test a set of criteria. The questionnaire was answered by professionals in charge of 46 interventions carried out in 12 European countries, and collected detailed information about each intervention. Third-party experts scored the interventions using the set of evaluation criteria proposed. RESULTS: Nine criteria to guide and evaluate interventions were proposed: relevance, appropriateness, applicability, innovation, quality assurance, adequacy of resources, effectiveness in the process, effectiveness in results and mainstreaming. A working definition was drawn up for each one. These criteria were then used to evaluate the interventions identified. CONCLUSIONS: The set of criteria drawn up to guide the design, implementation and evaluation of interventions to reduce health inequalities in PHC will be a useful instrument to be applied to interventions under development for culturally, politically and socio-economically diverse PHC contexts throughout Europe.

RESUMO

The structure of the title compound, [Fe(C5H5)(C15H13O2)], consists of a ferrocenyl moiety and a 2-meth-oxy-phenyl group linked through a prop-2-en-1-one spacer in an E conformation. In the ferrocene unit, the substituted cyclo-penta-dienyl (Cps) ring and the unsubstituted cyclo-penta-dienyl ring (Cp) are almost parallel to one another [dihedral angle = 1.78 (14)°], and the Cp and Cps rings are in a gauche conformation. The benzene ring is twisted by 10.02 (14) and 11.38 (11)° with respect to the Cp and Cps rings, respectively. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds into supra-molecular chains running along the b-axis direction.

RESUMO

This study sought to assess the association between illicit opioid use and accelerated epigenetic aging (A.K.A. DNAm Age) among people of African ancestry who use heroin. DNA was obtained from participants with opioid use disorder (OUD) who confirmed heroin as their primary drug of choice. Clinical inventories of drug use included: the Addiction Severity Index (ASI) Drug-Composite Score (range: 0-1), and Drug Abuse Screening Test (DAST-10; range: 0-10). A control group of participants of African ancestry who did not use heroin was recruited and matched to heroin users on sex, age, socioeconomic level, and smoking status. Methylation data were assessed in an epigenetic clock to determined and compare Epigenetic Age to Chronological Age (i.e., age acceleration or deceleration). Data were obtained from 32 controls [mean age 36.3 (±7.5) years] and 64 heroin users [mean age 48.1 (±6.6) years]. The experimental group used heroin for an average of 18.1 (±10.6) years, reported use of 6.4 (±6.1) bags of heroin/day, with a mean DAST-10 score of 7.0 (±2.6) and ASI Score of 0.33 (±0.19). Mean age acceleration for heroin users [+0.56 (± 9.5) years] was significantly (p< 0.05) lower than controls [+5.19 (± 9.1) years]. This study did not find evidence that heroin use causes epigenetic age acceleration.

RESUMO

Context: An emergency medical nurse is a health professional who operates at a very high level in the field of emergencies. The nurses of the critical area departments of the Territorial Emergency Department currently operate in the Sardinian helicopter rescue service. The effectiveness of the treatment that these nurses administer can be attributed to the quality of the previous and recurrent training that this unit must undergo. Objective: This study's aim was to investigate the role of civil and military helicopter nurses in the context of Italian medical aid. Methods: A qualitative study, with a phenomenological approach, was conducted by interviewing 15 emergency medical nurses, using detailed recordings and transcripts. These findings were then compared to understand how nurses work outside their department of origin, how their training has influenced their ability to establish themselves outside it, and thus their ability to become part of a context considered to be of the highest level. Participants and research context: The personnel interviewed in this study were those who were working in the helibases of Cagliari, Olbia, and Alghero. The limitations of this study are linked to the impossibility of obtaining an internship at a company, because, at the time of the study, an agreement between the university and the Areus company was not active. Ethical considerations: Participation in this research was completely voluntary. In fact, the participants could cease participating at any time. Results: This study revealed issues related to training, preparation, motivation to carry out the role held, nursing autonomy, the willingness to collaborate between the various rescue organizations, the use of the helicopter rescue service, and possible improvements for this service. Conclusions: civil air rescue nurses can deepen their knowledge by examining the work of military air rescue nurses, because, although the operational contexts are different, some techniques used in a hostile environment are also applicable to civilian environments. By doing so, nurses could become independent team leaders for all intents and purposes, managing their own training, preparation, and technical skills.

RESUMO

OBJECTIVE: Studies examining the associations between decision-making (DM) and cannabis use (CU) often use cross-sectional, adult samples, and composite scores or single tasks to assess DM. The present study explored differential associations between tasks assessing DM under various risk conditions (i.e., ambiguous vs. explicit; gain vs. loss) and CU frequency, CU-related problems, and CU disorder (CUD) onset across a 2-year period within adolescence. METHOD: Adolescents (n = 401, 90% Hispanic) aged 14-17 at baseline participated in five biannual assessments. CU frequency, CU-related problems, and CUD were assessed using the Drug Use History Questionnaire, Marijuana Problems Scale, and Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, fourth edition, respectively. DM was assessed using the Iowa gambling task (IGT), Game of Dice Task (GDT), and Cups Task. We used latent growth curve modeling to examine bidirectional associations between DM and escalation in CU frequency and CU-related problems, and discrete time survival analyses to determine whether baseline performance across DM tasks predicted CUD onset. RESULTS: Baseline performance on the GDT predicted greater escalation in CU (ß = .200, p = .008) and CU-related problems (ß = .388, p = .035). No other significant associations were found. CONCLUSIONS: DM under explicit risk may be a more salient risk factor for escalating CU and CU-related problems than DM under ambiguous risk. Deficits in executive functioning could partially explain the results. Findings suggest that neurocognitive development should inform prevention and intervention efforts focused on reducing CU. Given the exploratory nature of the present study, replication of findings is needed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

Breast cancer is currently the most commonly diagnosed cancer, with 287,850 new cases estimated for 2022 as reported by the American Cancer Society. Therefore, finding an effective treatment for this disease is imperative. Chalcones are α,ß-unsaturated systems found in nature. These compounds have shown a wide array of biological activities, making them popular synthetic targets. Chalcones consist of two aromatic substituents connected by an enone bridge; this arrangement allows for a large number of derivatives. Given the biological relevance of these compounds, novel ferrocene-heterocycle-containing chalcones were synthesized and characterized based on a hybrid drug design approach. These heterocycles included thiophene, pyrimidine, thiazolyl, and indole groups. Fourteen novel heterocyclic ferrocenyl chalcones were synthesized and characterized. Herein, we also report their cytotoxicity against triple-negative breast cancer cell lines MDA-MB-231 and 4T1 and the noncancer lung cell line MRC-5. System 3 ferrocenyl chalcones displayed superior anticancer properties compared to their system 1 analogues. System 3 chalcones bearing five-membered heterocyclic substituents (thiophene, pyrazole, pyrrole, and pyrimidine) were the most active toward the MDA-MB-231 cancer cell line with IC50 values from 6.59 to 12.51 µM. Cytotoxicity of the evaluated compounds in the 4T1 cell line exhibited IC50 values from 13.23 to 213.7 µM. System 3 pyrazole chalcone had consistent toxicity toward both cell lines (IC50 ∼ 13 µM) as well as promising selectivity relative to the noncancer MRC-5 control. Antioxidant activity was also evaluated, where, contrary to anticancer capabilities, system 1 ferrocenyl chalcones were superior to their system 3 analogues. Antioxidant activity comparable to that of ascorbic acid was observed for thiophene-bearing ferrocenyl chalcone with EC50 = 31 µM.

RESUMO

BACKGROUND AND AIMS: Although poor decision-making (DM) has been correlated with problematic cannabis use (CU), cross-sectional designs make it difficult to determine whether poor DM represents an antecedent and/or consequence of CU. The current study measured bidirectional associations between CU and DM among adolescents over 2 years and compared these findings to those observed with episodic memory, which is consistently reported as a consequence of CU. We also measured the role of DM as a risk factor for cannabis use disorder (CUD) onset. DESIGN: Two-year longitudinal study with five bi-annual assessments. PARTICIPANTS: Participants were 401 adolescents aged 14-17 years at baseline. SETTING: Miami, Florida, USA. MEASUREMENTS: CU frequency and CUDs were assessed at each time-point through the Drug Use History Questionnaire and Structured Clinical Interview for DSM-IV, respectively. Neurocognition was assessed at odd time-points throughout the Iowa Gambling Task, Game of Dice Task and Cups Task [decision-making (DM)] and the Wechsler Memory Scale IV and California Verbal Learning Test II (episodic memory). We used latent growth curve modeling to examine bidirectional influences between CU and neurocognition over time. We applied discrete time survival analyses to determine whether baseline DM predicted CUD onset. FINDINGS: Greater lifetime CU frequency was associated with poorer episodic memory at baseline (bs = -14.84, -16.44, Ps = 0.038, 0.021). Greater CU escalation predicted lesser gains in immediate episodic memory (b = -0.05, P = 0.020). Baseline DM did not predict CU escalation (b = 0.07, P = 0.421), nor did escalation in CU predict changes in DM (b = 0.02, P = 0.352). Baseline DM also did not predict CUD onset (adjusted OR = 1.01, 95% confidence interval = 0.98-1.06). CONCLUSIONS: This study replicates findings that poorer episodic memory in adolescents appears to be a consequence of cannabis use, even among adolescents at earlier stages of use. Poor decision-making does not appear to be either a consequence of or a risk factor for escalating cannabis use or onset of cannabis use disorder among adolescents.

RESUMO

Millepora is a relatively species-rich genus of hydrocorals, with 16 species distributed around the globe. It is considered an important reef building cnidarian. The current diversity of Caribbean Millepora species consists of Millepora complanata, M. alcicornis, M. squarrosa and M. striata. Here, we report the de novo transcriptome assembly and phylotranscriptomic analysis of M. alcicornis, M. complanata, M. squarrosa and a undescribed morphotype (Millepora sp.) found in exposed Thalassia beds and mangrove areas in southwest Puerto Rico. Over 345 million sequence reads were obtained for the analysis of the Millepora transcriptomes (Illumina HiSeq4000; 2x150bp). The analysis pipeline consisted of assembly with Trinity, BUSCO, RSEM and ORFs calling for each transcriptome, followed by ontology (Blast2GO) and phylogenetic analysis. The phylogenetic analysis was performed after selecting homologous genes among the transcriptomes, resulting in 10,596 sequences. Concatenation analysis (Maximum Likelihood and Bayesian inference) and a coalescence-based analysis were performed to the dataset too. Concatenation analysis yielded a topology supporting a clade of M. complanata and M. alcicornis, with Millepora sp. outside this clade and M. squarrosa as an outgroup. The coalescence-based tree estimation analysis (ASTRAL-II), presented a different topology placing M. alcicornis and Millepora sp. as sister taxa, rather than grouping with M. alcicornis with M. complanata. Our coalescence analysis indicated that there is a high degree of incomplete lineage sorting, suggesting a very recent time of species emergence among three out of the four Caribbean Millepora species. Calculations of ABBA-BABA statistics derived from transcriptome-wide SNP data indicate the possible presence of introgression between Millepora complanata and M. alcicornis.

RESUMO

The title ferrocene derivative, [Fe(C5H5)2(C8NO2)], including an alkyne bonded to a para-nitro-phenyl substituent, which was synthesized from a copper-free Sonogashira cross-coupling reaction between ethynylferrocene and 4-bromo-1-nitro-benzene, crystallizes in the P21/n space group. In the ferrocene unit, the penta-dienyl (Cps) rings are in an eclipsed conformation. The angle of rotation between the substituted cyclo-penta-dienyl ring and the p-nitro-phenyl group is 6.19 (10)°, yielding a quasi-linear extension of the ferrocenyl substitution. Important inter-molecular inter-actions arise from π-π stacking between the Cp rings and the p-nitro-phenyl, from corners of the Cp rings that are perpendicularly aligned, and between the O atoms from the nitro substituent and carbons at the corners of the Cp rings, propagating along all three crystallographic axes.

RESUMO

Community resilience is a community's ability to maintain functioning (ie, delivery of services) during and after a disaster event. The Composite of Post-Event Well-Being (COPEWELL) is a system dynamics model of community resilience that predicts a community's disaster-specific functioning over time. We explored COPEWELL's usefulness as a practice-based tool for understanding community resilience and to engage partners in identifying resilience-strengthening strategies. In 2014, along with academic partners, the New York City Department of Health and Mental Hygiene organized an interdisciplinary work group that used COPEWELL to advance cross-sector engagement, design approaches to understand and strengthen community resilience, and identify local data to explore COPEWELL implementation at neighborhood levels. The authors conducted participant interviews and collected shared experiences to capture information on lessons learned. The COPEWELL model led to an improved understanding of community resilience among agency members and community partners. Integration and enhanced alignment of efforts among preparedness, disaster resilience, and community development emerged. The work group identified strategies to strengthen resilience. Searches of neighborhood-level data sets and mapping helped prioritize communities that are vulnerable to disasters (eg, medically vulnerable, socially isolated, low income). These actions increased understanding of available data, identified data gaps, and generated ideas for future data collection. The COPEWELL model can be used to drive an understanding of resilience, identify key geographic areas at risk during and after a disaster, spur efforts to build on local metrics, and result in innovative interventions that integrate and align efforts among emergency preparedness, community development, and broader public health initiatives.

RESUMO

In October 2012, Superstorm Sandy had a wide impact on the public across New York City (NYC). The NYC Department of Health and Mental Hygiene (DOHMH) activated its incident command system (ICS) and deployed a liaison officer (LNO) to the NYC Emergency Operations Center (EOC) at NYC Emergency Management (NYCEM) 24 hours a day for 6 weeks. This prolonged response period, coupled with environmental effects on NYC's coastal communities, increased public awareness of Sandy's health impacts, requiring a broad scope of interagency coordination and operational input from the liaison officer. Liaison officers involved in this response later conducted a content analysis of issues handled throughout Sandy, to better understand the skill set required to serve in this role, identify greater staff depth, integrate liaison officers into DOHMH exercises, and update just-in-time training provided before liaison officers deploy. This analysis revealed defined training topics for liaison officers to improve staff performance and effectiveness in leading interagency coordination during emergency responses. Topics include resources, staffing, data management, public messaging, and vulnerable populations, and these topics have since been used to revamp liaison officer training and guide policy changes in the liaison officer job charter. Targeted use of liaison officers to support development and implementation and to coordinate response objectives with local, state, and federal partners has only become more important. This analysis continues to influence how DOHMH defines its citywide agency response role, to inform how best to staff and train liaison officers to respond, and to pose lessons for other jurisdictions seeking to maximize the effectiveness of liaison officers deployed in emergencies.

RESUMO

OBJECTIVE: To summarize ways that networks of community-based organizations (CBO), in partnership with public health departments, contribute to community recovery from disaster. METHODS: The study was conducted using an online survey administered one and 2 years after Hurricane Sandy to the partnership networks of 369 CBO and the New York Department of Health and Mental Hygiene. The survey assessed the structure and durability of networks, how they were influenced by storm damage, and whether more connected networks were associated with better recovery outcomes. RESULTS: During response and recovery, CBOs provide an array of critical public health services often outside their usual scope. New CBO partnerships were formed to support recovery, particularly in severely impacted areas. CBOs that were more connected to other CBOs and were part of a long-term recovery committee reported greater impacts on the community; however, a partnership with the local health department was not associated with recovery impacts. CONCLUSION: CBO partners are flexible in their scope of services, and CBO partnerships often emerge in areas with the greatest storm damage, and subsequently the greatest community needs. National policies will advance if they account for the dynamic and emergent nature of these partnerships and their contributions, and clarify the role of government partners.
