AbstractExtreme precipitation events are a serious threat to societal well-being over rainy areas such as Bangladesh. The reliability of studies of extreme events depends on data quality and their spatial and temporal distribution, although these subjects remain knowledge gaps in many countries. This work focuses on the analysis of four satellite-based precipitation products for monitoring intense rainfall events: the Climate Hazards Group Infrared Precipitation with Station Data (CHIRPS), the PERSIANN-Climate Data Record (PERSIANN-CDR), the Integrated Multisatellite Retrievals (IMERG), and the CPC Morphing Technique (CMORPH). Five indices of intense rainfall were considered for the period 2000-2019 and a set of 31 rain gauges for evaluation. The number and amount of precipitation associated with intense rainfall events are systematically underestimated or overestimated throughout the country. While random errors are higher over the wetter and higher-elevation north- and southeastern parts of Bangladesh, biases are more homogeneous. CHIRPS, PERSIANN-CDR and IMERG perform similar capturing total seasonal rainfall, but variability is better represented by CHIRPS and IMERG. Better results were obtained by IMERG, followed by PERSIANN-CDR and CHIRPS, in terms of climatological intensity indices based on percentiles, although the three products exhibited systematic errors. IMERG and CMORPH systematically overestimate the occurrence of intense precipitation events. IMERG showed the best performance representing events over a value of 20 mm/day; CMORPH exhibited random and systematic errors strongly associated with a poor representation of interannual variability in seasonal total rainfall. The results suggest that the datasets have different potential use and such differences should be considered in future applications regarding extreme rainfall events and risk assessment in Bangladesh.
Intraseasonal Sea Level Variability in the Persian Gulf

AbstractSatellite observations are used to establish the dominant magnitudes, scales, and mechanisms of intraseasonal variability in ocean dynamic sea level (ζ) in the Persian Gulf over 2002–15. Empirical orthogonal function (EOF) analysis applied to altimetry data reveals a basinwide, single-signed intraseasonal fluctuation that contributes importantly to ζ variance in the Persian Gulf at monthly to decadal time scales. An EOF analysis of Gravity Recovery and Climate Experiment (GRACE) observations over the same period returns a similar large-scale mode of intraseasonal variability, suggesting that the basinwide intraseasonal ζ variation has a predominantly barotropic nature. A linear barotropic theory is developed to interpret the data. The theory represents Persian Gulf average ζ () in terms of local freshwater flux, barometric pressure, and wind stress forcing, as well as ζ at the boundary in the Gulf of Oman. The theory is tested using a multiple linear regression with these freshwater flux, barometric pressure, wind stress, and boundary ζ quantities as input and as output. The regression explains 70% ± 9% (95% confidence interval) of the intraseasonal variance. Numerical values of regression coefficients computed empirically from the data are consistent with theoretical expectations from first principles. Results point to a substantial nonisostatic response to surface loading. The Gulf of Oman ζ boundary condition shows lagged correlation with ζ upstream along the Indian subcontinent, Maritime Continent, and equatorial Indian Ocean, suggesting a large-scale Indian Ocean influence on intraseasonal variation mediated by coastal and equatorial waves and hinting at potential predictability. This study highlights the value of GRACE for understanding sea level in an understudied marginal sea.
Testimonio at 50
Authors: Escobar Guadalupe 
Published: March 2021

A reassessment of the testimonio genre over the past five decades reveals continuities of state-sponsored violence from the revolutionary period to the present. An analysis of Pamela Yates’s 500 Years: Life in Resistance (2017) and Katia Lara’s Berta vive (Berta Lives, 2016) shows Cold War reverberations, unfolding deeper histories of dispossession and legacies of resistance. The first uncovers entangled issues of Guatemalan genocide disavowal and extractive industry while the second denounces the political feminicide of the Honduran environmental activist Berta Cáceres. Both testimonial documentaries mobilize an “archive effect” to contest the optic of colonial capitalism through the ecofeminist perspectives of indigenous women activists. Una reevaluación del género del testimonial durante las últimas cinco décadas revela la continuidad de la violencia estatal desde el período revolucionario hasta el presente. Un análisis de 500 Years: Life in Resistance (2017) de Pamela Yates y Berta vive (2016) de Katia Lara da cuenta de las reverberaciones de la Guerra Fría, desplegando historias más profundas de desposesión y legados de resistencia. La primera obra muestra los intrincados hilos en torno a la negación del genocidio guatemalteco y la industria extractiva, mientras que el segundo denuncia el feminicidio político de la activista ambiental hondureña Berta Cáceres. Ambos documentales testimoniales utilizan un “efecto de archivo” para impugnar la óptica del capitalismo colonial a través de las perspectivas ecofeministas de las activistas indígenas.

Authors: Bacsán Gabriela 
Published: March 2021

The mirror reflections of Junior, the young protagonist of Mariana Rondón’s film Pelo malo, attempting to straighten his hair for a school photograph reveal the racialized, gendered, sexualized, and classed aspects of normative subjecthood in Venezuela. An examination of the circumstances that frame each mirror reflection and the reactions they elicit in his mother and grandmother and of Junior’s efforts to constitute himself as a normative child reveals the possibilities the film presents for existing outside of normativity. Los reflejos en el espejo de Junior, el joven protagonista de la película Pelo malo de Mariana Rondón, quien intenta alaciar su cabello para una fotografía escolar, revelan los aspectos raciales, de género, sexuales y de clase de la subjetivación normativa en Venezuela. Un análisis de las circunstancias que enmarcan cada reflejo y las reacciones que estas provocan en su madre y abuela, así como los esfuerzos del mismo Junior por constituirse como un niño normativo, revela las posibilidades que nos presenta la película para existir fuera de la normatividad.

Purpose The primary aim of this pilot study was to examine the feasibility of codelivering a mental health intervention with an evidence-based type 2 diabetes (T2DM) boot camp care management program. The preliminary impact of participation on symptom scores for depression and anxiety and A1C was also examined. Methods This was a 12-week, non-randomized pilot intervention conducted with a convenience sample of adults with uncontrolled T2DM and moderate depression and/or anxiety at an urban teaching hospital. Co-management intervention delivery was via in-person and telehealth visits. Participants were assessed at baseline and 90 days. Results Participants (n = 18) were African American, majority female (83%), and age 50.7 ± 13.4 years. Significant improvements in mental health outcomes were demonstrated, as measured by a reduction in Patient Health Questionnaire − 9 scores of 2.4 ± 2.9 ( P = .01) and in Generalized Anxiety Disorder − 7 scores of 2.3 ± 1.9 ( P = .001). The pre-post intervention mean A1C improved by 3.4 ± 2.1 units from 12% ± 1.4% to 8.5% ± 1.7% ( P < .001). Conclusion The data generated in this pilot support the feasibility of delivering a diabetes and mental health co-management intervention using a combination of in-person and telemedicine visits to engage adults with T2DM and coexisting moderate depression and/or anxiety. Further research is warranted.

Published: March 2021

Background: Hospitals offer snacks for sale to patients, staff and visitors. Aim: As food choice is heavily influenced by the options available, the present study (a) audited snack availability and purchase in NHS hospital sites across a large UK city; and (b) tested the potential effects of changes to this availability in an online choice experiment. Methods: In Study 1 (audit), single-serve snacks ( n=376) available in 76 hospital food retail units were audited. Purchasing data were obtained from six food retail units over four weeks (27,989 sales). In Study 2 (online experiment), participants ( n=159) chose snacks from pictured ranges containing 25% (minority), 50% (equivalent) or 75% (majority) healthy options. Results: Available single-serve snacks varied markedly in calorie (18–641 kcals), fat (0–39 g), sugar (0.1–76 g) and salt (0–2.9 g). Only 30% of available snacks were healthy options and only 25% of the most commonly purchased snacks were healthy options. In Study 2, snack choice was significantly associated with the availability of healthy options in the choice array (X2 (2)= 59.71, p<.01). More participants made healthy choices when product ranges contained 75% healthy options compared to 50% (p<.01) and 50% healthy options compared with 25% (p<.01). Conclusions: Healthy snacks are readily available in NHS sites but there is a greater relative variety of unhealthy snack products. Many consumers continue to purchase unhealthy items. Further increasing the availability and variety of healthy options may support consumers to make healthier choices.

Published: March 2021

Introduction: Extracorporeal membrane oxygenation (ECMO) is a resource-intense modality whose usage is expanding rapidly. It is a costly endeavor and best conducted in a multidisciplinary setting. There is a growing impetus to mitigate the mortality and costs associated with ECMO. We sought to examine the impact of complications on mortality and hospital costs in patients on ECMO. Methods: Using the NIS database, we performed multivariable logistic regression to assess the influence of complications on the primary outcome, in-hospital mortality. Similarly, we performed multivariable survey linear regression analysis to evaluate the effect of the complications on hospital costs. Results: Of the 12,637 patients supported using ECMO between 2004 and 2013, 9836 (78%) developed at least one complication. The three most common complications were acute kidney injury (32.8%), bloodstream infection (31.8%), and bleeding (27.8%). An ECMO hospitalization with no complications was associated with median costs of $53,470, a single complication with costs of $97,560, two complications with costs of $139,035, and three complication with costs of $162,284. A single complication was associated with a 165% increase in odds of mortality. Two or three complications resulted in 375% or 627% higher odds of mortality, respectively. Having one, two, or three complications was associated with 24%, 38%, or 38% increase in median costs respectively (Figure 1). Complications associated with the highest median costs were central line-associated bloodstream infection $217,751; liver failure $176,201; bloodstream infection $169,529. Conclusion: In-hospital mortality and costs increase with each incremental complication in patients on ECMO. Accurate prediction and mitigation of complications is likely to improve outcomes and cost.
Profile of a short-acting κ-antagonist, LY2795050, on self-grooming behaviors, forced swim test and locomotor activity: sex comparison in mice

Published: March 2021

Background: Novel short-acting κ(kappa)-opioid receptor selective antagonists are translational tools to examine the impact of the κ-receptor/dynorphin system in assays related to central nervous system dysfunction (e.g., substance use disorders, anhedonia and depression). The effects of such compounds have been compared in males and females under very limited conditions. Aims: The goal of this study was to examine potential sex differences in the effects of a κ-agonist and a short-acting κ-antagonist in an ethologically relevant test of anhedonia, the “splash test” of self-grooming, and also in the forced swim test and in locomotor activity. Methods: We examined the dose-dependence of grooming deficits caused by the κ-agonist U50,488 (0.1–3.2 mg/kg intraperitoneal (i.p.)) in gonadally intact adult male and female C57BL/6J mice. We then compared the effects of the short-acting κ-antagonist LY2795050 ((3-chloro-4-(4-(((2S)-2-pyridin-3-ylpyrrolidin-1-yl)methyl) phenoxy)benzamide)); 0.032–0.1 mg/kg i.p.) in blocking grooming deficits caused by U50,488 (3.2 mg/kg). The effects of LY2795050 were also studied in the forced swim test (FST). The effects of LY2795050 in blocking the locomotor depressant effects of U50,488 (10 mg/kg) were also studied. Results: U50,488 produced dose-dependent grooming deficits in male and female mice, and LY2795050 prevented these effects. In contrast, LY2795050 decreased immobility in the FST in males at a dose of 0.1 mg/kg, but not in females, up to a dose of 0.32 mg/kg. Also, LY2795050 (0.32 mg/kg) prevented and also reversed the locomotor-depressant effects of U50,488 (10 mg/kg), in males and females. Conclusions: This study further implicates the κ-receptor system in ethologically relevant aspects of anhedonia, and confirms sexual dimorphism in some behavioral effects of novel κ-antagonists.

Objective In this study, we aimed to explore the effect of continuous nursing care on children with pneumonia, including patient survival and quality of life. Methods We included 90 children with pneumonia who were admitted to our hospital from May 2017 to June 20, 2017. We established two patient groups (45 children per group); the routine group received general care and the continuous group received continuous nursing care. We observed the correlation among nursing effectiveness, clinical symptom improvement, quality of life, satisfaction, and complications. Results Our results showed that effectiveness in the continuous care group was 95.55%, significantly higher than that in the routine group (75.55%). Duration of hypothermia (1.75 ± 0.65 days), time to cough remission (4.24 ± 1.12 days), time to rale remission (4.15 ± 0.89 days), and time to remission of shortness of breath (2.65 ± 0.65 days) in the continuous group was shorter than those in the routine group. The incidence of total complications in the continuous group was 8.89%, which was significantly lower than that in the routine group (26.67%). The continuous care group showed greater improvement after intervention. Conclusion Continuous care in children with pneumonia can help to reduce illness severity, pain, heart and lung failure, and serve to avoid medical disputes.
Patient Statement: Chemical Sensitivity One Victim's Perspective
Authors: Wilson Cynthia 
Published: March 2021

Not a day goes by that I don't miss my old life and the old me. To illustrate how my life has changed, I have two brief stories. In 1982, I developed a lending procedure in conjunction with Banker's Life Insurance Company that enabled commercial real estate developers to secure permanent financing for property that had not yet been developed in essence using a permanent loan in place of a construction loan. It fixed the interest rate, at a time when new construction rates were bankrupting many projects and it allowed the developer to invest the excess funds to offset interest expenses. I received national recognition for this loan. In 1989, the police found me wandering around in 15 inches of snow, in below zero weather with no shoes or coat. The officer took me to the hospital because I was obviously disoriented. I didn't even know my name or where I lived. These stories show the disparity between my life as a successful, independent business woman and my life as someone who is chemically disabled.
Neurospect Findings in Patients Exposed to Neurotoxic Chemicals

Published: March 2021

Exposures to neurotoxic chemicals such as pesticides, glues, solvents, etc. are known to induce neurologic and psychiatric symptomatology. We report on 41 patients 16 young patients (6 males, 10 females, age 34 8 yrs.) and 25 elderly patients (9 males, 16 females, age 55 7 yrs). Fifteen of them were exposed to pesticides, and 29 to solvents. They were studied with quantitative and qualitative analysis of regional cerebral bood flow (rCBF), performed with 30 mCi of Xe-133 by inhalation, followed by 30 mCi of Tc-HMPAO given intravenously. Imaging was performed with a brain dedicated system, distribution of rCBF was assessed with automatic ROI definition, and HMPAO was normalized to maximal pixel activity in the brain. Results of Xe rCBF are expressed as mean and S.D. in ml/min/100g, and HMPAO as mean and S.D. uptake per ROI, and compared with age-matched controls 10 young and 20 elderly individuals. Neurotoxics HMPAO Uptake Young Elderly R. Orbital frontal R. Dorsal frontal .70 .66 p < 0.05 R. Temporal .64 p < 0.001 R. Parietal .66 .66 We conclude that patients exposed to chemicals present with diminished CBF, worse in the right hemisphere, with random presentation of areas of hypoperfusion, more prevalent in the dorsal frontal and parietal lobes. These findings are significantly different from observations in patients with chronic fatigue and depression, suggesting primary cortical effect, possibly due to a vasculitis process.

Chemical sensitivities display a recurrent pattern on scintigraphic examinations of the brain. The pattern can include mismatching between early and late imaging, multiple hot and cold foci distributed throughout the cortex without regard to lobar distribution (salt and pepper pattern), temporal asymmetries, and sometimes increased activity in the basal ganglia. This study used Desert Shield/Desert Storm veterans who present with abnormal neurological and psychological symptoms as a model to exhibit abnormalities by brain scintigraphy. These are typical of those seen in patients with documented exposure to neurotoxic compounds who develop a clinical syndrome that has been termed chemical sensitivity. Exposure to cocaine, alcohol, and other substances of abuse can result in abnormal scintigrams of the brain using tracers such as [technetium 99m]hexamethylpropyleneoxime. This study used techniques combining regional cerebral blood flow data with delayed distributional data after the intracellular conversion of the tracer into a hydrophilic molecule. In addition to delayed image abnormalities, a mismatch occurs in the regional activity between the two image sets of the veterans. This degree of mismatch was not seen in control subjects who were screened for avoidance of neurotoxic agents. Patterns identified from examinations performed on patients with known exposure to petroleum distillates, pesticides and other materials linked with neurotoxicity were identified in some veterans of the Desert Shield/Desert Storm operation. A single case of repeated examinations on a veteran showed a reversion of these patterns toward normal after therapy. This reversion followed independent assessments of clinical improvement.

Introduction: Microcirculatory alterations characterize septic shock; increased blood lactate level has been described as markers of microcirculation alteration in patients with septic shock. Although useful, this serological analysis is not always feasible in all settings worldwide. Objective: To determine if a prolonged capillary refilling is a predictor of mortality in patients with septic shock. Methodology: A 10-months prospective cohort study was carried out on 175 patients admitted to the Intensive Care Unit (ICU) with the diagnosis of septic shock. The capillary refilling time (CRT) was evaluated Immediately upon admission and after 6 hours post-resuscitation. Traditional tissue perfusion markers were also used to compare and analyze their predictive value on mortality at 28 days. Results: The area under the ROC curve (AUC) to estimate mortality in patients with septic shock with CRT at admission was 0.666 (0.584-0.748), while at 6 hours was 0.819 (0.753-0.885), with a cut-off point of 4.5 seconds at admission (PPV 52.87% NPV 72.73%) and 3.5 sec at 6 hours (PPV 95.56% NPV 79.23%). In those with CRT > 3.5 seconds at 6 hours, they had a RR of 4.60, while a CRT > 4.5 seconds at admission had a RR of 1.94, with a non-survivor proportion of 95.56% for a CRT > 3.5 sec at 6 hours vs 20.77% for CRT ≤ 3.5 sec ( P value < 0.001). The CRT at 6 hours showed significant differences in the survival curves with P-value < 0.001, where for values > 3.5 sec, survival at 28 days was 4.44% vs 79.20% for values ≤ 3.5 sec. Conclusion: CRT is a strong predictor of mortality in patients with septic shock. Evaluating changes in CRT during resuscitation from septic shock might be used as an important clinical tool to predict mortality; especially in low-resources settings where using other biomarkers might be sometimes difficult.
