Public perception of climate change and disaster preparedness: Evidence from the Philippines

The Philippines is highly susceptible to both geophysical and climate-related disasters. This article explores Filipinos knowledge and perception of climate change and their association with what action Filipinos take to prepare for rapid onset natural hazards such as typhoons. Data for this study were collected from a nationally representative random survey of 5,184 adults conducted between March and April of 2017. Filipinos self-report relatively low levels of knowledge of climate change and cited increased temperatures, shifts in seasons, and heavier rains as the most likely consequences. Levels of disaster preparedness in the Philippines differ widely by region. Although most Filipinos perceive that natural hazards are a risk to them, only a third of Filipinos undertake measures to prepare for disasters. Filipinos who perceive climate-related changes directly impacting their households report taking greater action to prepare for disasters. Filipinos who believe they have been directly impacted by climate-related changes are also more likely to prepare for disasters, take planning actions, and undertake material actions to prepare, such as dwelling improvements. Other factors associated with disaster preparedness include gender, membership in an association, wealth, risk perception, and prior exposure to and losses due to disasters. The findings imply that, while posing different challenges and requiring different responses, adaptation to climate change and disaster preparedness are inherently associated and potentially mutually reinforcing. Policies and programs would arguably benefit from a more unified intervention framework that links climate change adaptation and disaster preparedness.     

Extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae in diabetic foot infections

Aims: Diabetic foot lesions are a major medical, social, and economic problem and are the leading cause of hospitalization for patients with diabetes, worldwide. ESBL-producing bacteria may not be detectable by routine disc diffusion susceptibility test, leading to inappropriate use of antibiotics and treatment failure. There is not much information on ESBL-producing organisms causing diabetic foot infection. An attempt was therefore made to study the ESBL-producing Escherichia coli and Klebsiella pneumoniae in diabetic foot patients with type 2 diabetes mellitus. Materials and Methods: A total of 134 isolates of E. coli and K. pneumoniae were obtained from tissue, pus swab, and wound swab samples from diabetic foot ulcers submitted for routine microbiological analysis during the period January to December 2005 from patients with diabetic foot infections who had type 2 diabetes mellitus, attending S. L. Raheja Hospital. The above isolates were tested for antimicrobial susceptibility by disc diffusion technique according to clinical and laboratory standards institute (CLSI) guidelines. The screening for ESBL production was done by phenotypic confirmatory test using ceftazidime disc in the presence and absence of clavulanic acid as recommended by CLSI. Results: Among the 134 isolates, 54 (40.29%) were E. coli and 80 (59.70%) were K. pneumoniae; among which, ESBL production was detected in 31 (23.13%) isolates. Of these 31, 15 (48.38%) were E. coli and 16 (51.61%) were K. pneumoniae. All the ESBL-producing isolates were found to be 100% sensitive to carbapenem (imipenem and meropenem). Mortality was found to be 3.22%, the cause of death being septicemia leading to multiple organ failure. Conclusions: The prevalence of ESBLs among members of Enterobacteriaceae constitutes a serious threat to the current beta-lactam therapy, leading to treatment failure and consequent escalation of costs. There is an urgent need to emphasize rational use of drugs to minimize the misuse of available antimicrobials.     

An assessment of the psychometric properties of the Stoplight Pain Scale in a Canadian paediatric emergency department

ObjectiveThis study aimed to validate a novel, three faced, colour-coded, action-oriented tool: The Stoplight Pain Scale (SPS).MethodsA prospective observational cohort study was conducted at a Canadian paediatric emergency department from November 2014 to February 2017. Patients aged 3 to 12 years and their caregivers were asked to rate pain using the SPS and the Faces Pain Scale-Revised (FPS-R). Pain was measured just before analgesia administration, 30 minutes after analgesia administration, and immediately following a painful procedure.ResultsA total of 227 patients were included; 26.9% (61/227) were 3 to 5 years old while 73.1% (166/227) were 6 to 12 years old. Using Cohen’s κ, agreement for SPS and FPS-R was ‘fair’ for children (0.28 [95% confidence interval {CI} 0.20 to 0.36]) and ‘poor’ for caregivers (0.14 [95% CI 0.07 to 0.21]), at initial measurement. The SPS had ‘fair’ agreement between child and caregiver scores, (0.37 [95% CI 0.27 to 0.47]), compared to FPS-R which showed ‘poor’ agreement (0.20 [95% CI 0.12 to 0.29]). Absolute agreement between child and caregiver SPS scores improved with repeat exposure; 30 minutes after analgesia administration, caregivers and children had fair agreement (κ=0.38, 95% CI 0.28 to 0.48); they had moderate agreement directly following painful procedures (κ=0.46, 95% CI 0.34 to 0.59). Overall, 72.4% (139/192) of children and 60.2% (118/196) of caregivers preferred SPS over FPS-R.ConclusionThe SPS demonstrates fair agreement with FPS-R for children and fair-moderate agreement between children and caregivers; agreement improved with repeat use. The SPS is simple and easy to use; it may have a role in empowering direct child and family involvement in pain management.     

Explanatory Models of Health and Disease Among South Asian Immigrants in Chicago

To identify concepts of health and disease as part of a study on designing culturally-targeted heart disease prevention messages for South Asians. We conducted qualitative, semi-structured interviews in English, Hindi and Urdu with 75 respondents from a federally qualified health center and at a community center for South Asian immigrants in Chicago, Illinois. Age ranged from 20 to 70 years; 60% were women; 60% held advanced degrees; 70% migrated to the US in the last 10 years; and 60% of the interviews were in Hindi or Urdu. Concepts of health and disease fell into four domains: behavioral, physical, psycho-social and spiritual. Muslim participants consistently evoked spiritual factors such as faith and prayer. Women more frequently included performing home duties and positive affect in their concept of health. Men more frequently cited behavioral factors such as smoking and drinking as the cause of disease. Many South Asians have a holistic conceptualization of health and disease, incorporating spiritual, physical and psycho-social factors. Health promotion strategies aimed at South Asians in the US should take into account this holistic model of health and disease, while also recognizing that variations exist within South Asians, by gender and religion.     

Developmental regulation of GTP-CH1 in the porcine lung and its relationship to pulmonary vascular relaxation

Nitric oxide (NO) plays an important role in lowering pulmonary vascular resistance after birth. However, in persistent pulmonary hypertension of the newborn (PPHN) NO-mediated dilation is dysfunctional. GTP-cyclohydrolase 1 (GTP-CH1) is the rate-limiting enzyme for the biosynthesis of 6R-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4) an essential cofactor for nitric oxide synthase (NOS) activity. Suboptimal levels of BH4 may result in NOS uncoupling and the subsequent generation of harmful superoxide anions. We therefore investigated the functional effects of supplementing BH4 and/or a superoxide dismutase mimetic (MnTMPyP) in porcine intrapulmonary arteries from normal animals and from a porcine model of PPHN. We investigated whether any functional effects of BH4 could be explained by changes in GTP-CH1 expression. Supplementation of BH4 significantly improved endothelium-dependent relaxations in arteries from 3- and 14-d-old healthy animals, whereas no effect was seen in vessels from younger animals and adults. GTP-CH1 protein expression was lowest at 3 and 14 d, suggesting a rate limitation of BH4 at this time. BH4 supplementation alone did not improve the relaxant response to acetylcholine in arteries obtained in a porcine model of PPHN. Furthermore, GTP-CH1 protein expression was normal for age. However, co-treatment with both BH4 and MnTMPyP restored endothelial function. GTP-CH1 is developmentally regulated in the pulmonary vasculature of neonates and this results in a functionally significant limitation of BH4. Although GTP-CH-1/BH4 levels alone do not explain the profound endothelial dysfunction seen in PPHN, increasing NO bioavailability by supplementing BH4 and quenching superoxide may prove to be therapeutically beneficial.     

A change in humidification system can eliminate endotracheal tube occlusion

PurposeInadequate airway humidification can result in endotracheal tube occlusion. There is evidence that heat and moisture exchangers (HMEs) are more prone to endotracheal tube occlusion than heated humidifiers (HHs) that contain a heated wire circuit. We aimed to compare the incidence of endotracheal tube occlusion while introducing a new dual-heated wire circuit HH in place of an established hydrophobic HME.Materials and MethodsThis was a prospective observational study. All patients who required intubation were included in our analysis. Univariate statistical analysis was performed using a Fisher exact test. P < .05 was considered statistically significant.ResultsThere were 158 patients in the HME group and 88 patients in the HH group. The incidence of endotracheal tube occlusion was 5.7% in the HME group and 0% in the HH group. Statistical analysis revealed a significant difference between the 2 groups (P = .02). In light of this finding, we changed our practice to provide humidification exclusively by HH. In the subsequent 18-month period, there were no further episodes of endotracheal tube occlusion.ConclusionsOur study demonstrates that there is a significant increase in the incidence of endotracheal tube occlusion when using a hydrophobic HME compared with an HH and that using a dual-heated wire circuit HH can eliminate endotracheal tube occlusion.
