ENVIRONMENTAL RESEARCH 2024; 252:118766. [PMID: 38583660 DOI: 10.1016/j.envres.2024.118766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 03/14/2024] [Accepted: 03/19/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND Sickle cell disease (SCD) is a genetic disorder and symptoms may be sensitive to environmental stressors. Although it has been hypothesized that exposure to outdoor air pollution could trigger acute SCD events, evidence is limited. METHODS We obtained SCD administrative data on hospital encounters in South Carolina from 2002 to 2019. We estimated outdoor air pollutant (particulate matter<2.5 μm (PM2.5), ozone (O3), and PM2.5 elemental carbon (EC) concentrations at residential zip codes using spatio-temporal models. Using a random bi-directional, fixed-interval case-crossover study design, we investigated the relationship between air pollution exposure over 1-, 3-, 5-, 9-, and14-day periods with SCD hospital encounters. RESULTS We studied 8410 patients with 144,129 hospital encounters. We did not observe associations among all patients with SCD and adults for PM2.5, O3, and EC. We observed positive associations among children for 9- and 14-day EC (OR: 1.05 (95% confidence interval (CI): 1.02, 1.08) and OR: 1.05 (95% CI: 1.02, 1.09), respectively) and 9- and 14-day O3 (OR: 1.04 (95%CI: 1.00, 1.08)) for both. CONCLUSIONS Our findings suggest that short-term (within two-weeks) levels of EC and O3 and may be associated with SCD hospital encounters among children. Two-pollutant model results suggest that EC is more likely responsible for effects on SCD than O3. More research is needed to confirm our findings.

Abstract
Background Patients with sickle cell disease (SCD) often present in the Emergency Department (ED) with acute and debilitating pain and other SCD-related complications. Objectives The objective is to analyze the causes of ED visits of pediatric patients with SCD, assess the burden of ED admission due to SCD in relation to other pediatric diseases, the treatment given, and the outcomes. Methods A prospective analytical study was conducted on children and adolescents with SCD, 1-14 years old who had been admitted to the ED at Basrah Maternity and Children Hospital over a six-month period. Patient's sociodemographic and clinical data, drug history, length of ED stay, complications, outcome, and readmissions were recorded. Results A total of 422 patients with SCD were admitted to ED during the study period representing 4.10% of the total admitted cases; 276(65.40%) of them were recruited in this study, and their mean age was 7.84 ±3.47 years. The main cause for ED admission was pain (73.91%), followed by infection (10.14%) and hemolytic crisis (6.15%). The mean duration of stay at ED was 6.11±1.87 hours. All admitted SCD patients had received analgesia; non-steroidal anti-inflammatory drugs (NSAIDs) were the commonest (80.4%), followed by acetaminophen (39.5%), and opioid narcotic (18.5%). Readmission within 30-days was reported in 82(29.71%) patients and was associated with the number of ED visits/last year (B=0.151, P=0.023), length of stay at ED (B=0.140, P=0.034) and severe disease (B=0.253, P<0.001). Conclusions Acute painful episodes were the main cause of ED admission. Although most patients with pain did receive NSAIDs, only a small percentage of them did receive opioids. About one-third of patients have been readmitted within 30 days, and readmission was associated with the number of ED visits/last year, disease severity, and length of ED stay. These findings can help in establishing local guidelines for managing such patients in the ED especially pain management.

Obeagu EI, Obeagu GU. Implications of climatic change on sickle cell anemia: A review. Medicine (Baltimore) 2024; 103:e37127. [PMID: 38335412 PMCID: PMC10860944 DOI: 10.1097/md.0000000000037127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 01/02/2024] [Accepted: 01/10/2024] [Indexed: 02/12/2024] Open
Abstract
Sickle cell anemia (SCA) is a hereditary blood disorder characterized by abnormal hemoglobin, causing red blood cells to assume a sickle shape, leading to various complications. Climate change has emerged as a significant global challenge, influencing environmental conditions worldwide. This paper explores the implications of climatic variations on the prevalence, management, and outcomes of SCA. Climate change affects weather patterns, leading to altered temperatures, increased frequency of extreme weather events, and variations in humidity levels. These changes can have a profound impact on individuals living with SCA. High temperatures exacerbate the symptoms of SCA, potentially triggering painful vaso-occlusive crises due to dehydration and increased blood viscosity. Conversely, cold temperatures may induce vaso-occlusion by causing blood vessels to constrict. Changes in rainfall patterns might also affect water accessibility, which is crucial for maintaining adequate hydration, particularly in regions prone to droughts. The management of SCA is multifaceted, involving regular medical care, hydration, and avoiding triggers that could precipitate a crisis. Adverse weather events and natural disasters can disrupt healthcare infrastructure and access to essential medications and resources for SCA patients, especially in vulnerable communities. To mitigate the implications of climatic change on SCA, interdisciplinary strategies are essential. These strategies may include enhancing healthcare systems' resilience to climate-related disruptions, implementing adaptive measures to address changing environmental conditions, and promoting public awareness and education on managing SCA amidst climate variability. In conclusion, climatic variations pose significant challenges for individuals with SCA, affecting the prevalence, management, and outcomes of the disease.

Oxygen gradient ektacytometry-derived biomarkers are associated with acute complications in sickle cell disease. Blood Adv 2024; 8:276-286. [PMID: 37976458 PMCID: PMC10824684 DOI: 10.1182/bloodadvances.2023011013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 09/26/2023] [Accepted: 10/18/2023] [Indexed: 11/19/2023] Open
Abstract
ABSTRACT We investigated the potential of the point of sickling (PoS; the pO2 tension at which red cells start to sickle), determined by oxygen gradient ektacytometry to serve as a biomarker associated with the incidence of acute sickle cell disease-related complications in 177 children and 50 adults. In the pediatric cohort, for every 10 mmHg increase in PoS reflecting a greater likelihood of sickling, the likelihood of an individual experiencing >1 type of acute complication increased; the adjusted odds ratio (aOR) was 1.65. For every 0.1 increase in minimum elongation index (EImin; reflecting improved red blood cell deformability at hypoxia), the aOR was 0.50. In the adult cohort, for every 10 mmHg increase in PoS, we found an aOR of 3.00, although this was not significant after correcting for multiple testing. There was a trend for an association between higher PoS and greater likelihood of vaso-occlusive episodes (VOEs; children aOR, 1.35; adults aOR, 2.22). In children, only EImin was associated with VOEs (aOR, 0.68). When data of both cohorts were pooled, significant associations with PoS and/or EImin were found for all acute complications, independently and when >1 type of acute complication was assessed. These findings indicate that oxygen gradient ektacytometry generates novel biomarkers and provides a rationale for further development of these biomarkers in the assessment of clinical severity, evaluation of novel therapies, and as surrogate clinical trial end points. These biomarkers may be useful in assessing efficacy of novel therapies like pyruvate kinase activators, voxelotor, and L-glutamine.

Abstract
Sickle cell disease (SCD) is the most common monogenic disorder, although the diversity and heterogenicity of clinical presentations render estimations of disease severity unpredictable. This cross-sectional study aimed to determine if laboratory markers could serve as indicators of SCD severity. We enrolled 90 adult patients with SCD with a mean age of 32.33 ± 11.84 years from the eastern province of Saudi Arabia, where SCD is more common than in other regions. Our study revealed a positive significant association between the number of hospitalizations and emergency visits with white blood cells (WBC) (R = 0.241, R = 0.207), respectively. Similarly, positive significant associations were found between the number of hospitalizations and emergency visits with platelets (R = 0.393, R = 0.276), respectively. Conversely, negative significant relationships were found between the number of hospitalizations and emergency visits (ER) with hemoglobin (Hb) F (R = -0.268, R = -0.263), respectively. Additionally, significant negative relationships were found between Hb F (R = -0.223) and the frequency of ICU admission. Only the number of hospitalizations and emergency visits annually were significantly predicted with P values of 0.021 and 0.038, respectively. Moreover, an increase in WBC was found to significantly increase the chance of undergoing splenectomy by 23.02%. SCD is a multisystemic disease with heterogeneous clinical presentations and disease severity. Inflammatory markers are valuable tools for better risk stratification and could be translated into developing new therapeutic strategies and modifying the treatment paradigm.

Abstract
BACKGROUND Sickle cell disease (SCD) is the most common inherited blood disorder, affecting primarily Black and Hispanic individuals. In 2016, 30-day readmissions incurred 95,445 extra days of hospitalization, $152 million in total hospitalization costs, and $609 million in total hospitalization charges. OBJECTIVES 1) To estimate hospital readmissions within 30 days among patients with SCD in the State of California. 2) Identify the factors associated with readmission within 30 days for SCD patients in California. METHODS We conducted a retrospective observational study of adult SCD patients hospitalized in California between 2005 and 2014. Descriptive statistics and logistic regression models were used to examine significant differences in patient characteristics and their association with hospital readmissions. RESULTS From 2,728 individual index admissions, 70% presented with single admission, 10% experienced one readmission, and 20% experienced ≥ two readmissions within 30 days. Significant predictors associated with zero vs. one readmission were male gender (OR=1.37, CI: 1.06-1.77), Black ethnicity (OR=3.27, CI: 1.71-6.27) and having Medicare coverage (OR=1.89, CI: 1.30-2.75). Lower likelihood of readmission was found in those with a Charlson Comorbidity index of three or more (OR=0.53, CI: 0.29-0.97). For zero vs. ≥ two readmissions, significant predictors were male gender (OR=1.43, CI: 1.17-1.74), Black ethnicity (OR=6.90, CI: 3.41-13.97), Hispanic ethnicity (OR=2.33, CI: 1.05-5.17), Medicare coverage (OR=3.58, CI: 2.68-4.81) and Medi-Cal coverage (OR=1.70, CI: 1.31-2.20). Lower likelihood for having two or more readmissions were associated with individuals aged 65+ (OR=0.97, CI: 0.96-0.98) and those with self-payment status (OR=0.32, CI: 0.12-0.54). CONCLUSIONS In California, male, Black, and Hispanic patients, as well as those covered by Medicare or Medi-Cal, were found to have an increased risk of hospital readmissions. Redirecting outpatient goals to address these patient populations and risk factors is crucial for reducing readmission rates.

Abstract
To investigate the influence of climate on hospitalizations of sickle cell anemia (SCA) adults and children, we analyzed the health and meteorological parameters from a metropolis (1999-2018). 1462 hospitalizations were coded for SCA patients in crisis (M:F = 715:747) and 1354 hospitalizations for SCA patients without crisis (M:F = 698:656) [age = 22.9 vs 15.2 years and duration of hospitalization (DoH) = 5.7 vs 4.4 days, respectively,]. More hospitalizations were for adults than children in crisis, and for children than adults without crisis. More children and adults were hospitalized in winter andspring than in summer and autumn Hospitalizations correlated positively with humidity (lag -5), maximum pressure (lag -2), mean pressure (lag -2), and thermal amplitude (lag -2), and negatively with maximum temperature (lag -3). DoH positively correlated with minimum temperature (lag -4). Understanding these complex associations would induce attitudinal/behavioral modifications among patients and their caregivers.

Abstract
Introduction Sickle cell disease (SCD) is a genetic blood disorder that affects the shape and function of red blood cells (RBCs), which can lead to several health problems affecting the quality of life. SCD can be treated with certain expensive treatments such as RBC transfusion, hydroxyurea, stem cell transplantation, gene therapy, or bone marrow transplant. However, some of the most common symptoms such as pain, anxiety, and stress can also be alleviated with alternative therapies like yoga. In light of this, there is a need for the development of a specific yoga module (YM) for SCD that can complement the current therapies. Objective To develop and validate a YM for SCD. Methodology Concise literature reports on yoga practices used for varied symptoms/comorbidities associated with SCD were compiled and presented to focus groups. Based on the presented report and personal experience, the focus group created a preliminary version of the module. The preliminary module was further refined based on content validity ratio (CVR) following module validation by 33 yoga experts. Results One hour ten minutes module developed by the focus group had in total 27 practices including, loosening exercises, asanas, pranayama, relaxation techniques, and meditation. After validation by the experts, 21 practices with a CVR ≥ 0.33 were retained. The predominant reason for excluding 12 practices was intensity, which may have some adverse effect on sickle cell comorbidities. Conclusion The module developed is the first validated module for SCD.

J Natl Med Assoc 2023; 115:441-453. [PMID: 37407379 DOI: 10.1016/j.jnma.2023.06.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 06/14/2023] [Indexed: 07/07/2023]
Abstract
BACKGROUND Sickle cell disease (SCD) is a public health problem. In absence of a pan-country intervention program in India, SCD prevalence is ascending without control. Since knowledge and perception of a community is a prerequisite for developing an intervention strategy, the current study was designed to assess it in a high SCD burden tribal-dominated district of Odisha. METHODS A mixed-method study combining qualitative and quantitative methods was conducted in the Kandhamal district, Odisha, India. A cross-sectional survey was conducted among randomly selected 1600 individuals, using a pre-tested questionnaire and 26 in-depth interviews were conducted with key informants. RESULTS Although 74.2% of the participants in the studied area had heard about the disease, only 13.6% know the cause of the disease. 69% had the knowledge to opt for modern medication. However, treatment compliance was poor, patients resort to using medications only during the crisis stage. Individuals who had knowledge about disease aetiology got to know about SCD from lived experiences of themselves, close relatives, or villagers and rarely from health workers. The community members had no clarity regarding which health centre to be approached for routine medication and management of SCD crisis. CONCLUSION The area is endemic for SCD, yet, the community lacks knowledge about the cause and treatment modality of the disease. In addition, currently there is no government-run intervention programme for screening and management of SCD related morbidity. Hence, a community based intervention strategy needs to be implemented urgently for enhancing the knowledge, perception, and aptitude related to SCD.

Abstract
Background Sickle cell disease (SCD) is the most common genetic blood disorder in Saudi Arabia. A limited number of studies have been conducted on SCD patients regarding their intensive care unit (ICU) admissions. We aimed to identify the cause of ICU admission in SCD patients and to identify predictors of mortality. Methodology We identified 64 patients with SCD, aged 14 years and older, who were admitted to the ICU of King Saud Medical City, Riyadh, Kingdom of Saudi Arabia, from January 1, 2017, to December 31, 2020. Results Acute chest syndrome was the most frequent primary diagnosis for ICU admission in 29 (45.3%) patients followed by vaso-occlusive crisis in 23 (35.9%) patients. Pregnancy in eight (12.5%) patients was the most prevalent co-existing condition. The median age was 29 years, with males comprising 45.3% and females comprising 54.7% of the study population. Arterial blood gas pH less than 7.2 on ICU admission (p= <0.001), hemodialysis support (p= 0.049), the use of vasopressors (p= 0.016), intubation (p= <0.001), and being intubated within the first 24 hours of ICU stay (p= 0.04) had a statistically significant association with mortality at ICU discharge out of all the variables tested. Mortality on ICU discharge was 7 (10.9%). Conclusion This was a retrospective study carried out in King Saud Medical City. Comparing the results of the study to those of similar ones conducted around the world revealed a low SCD ICU mortality rate. This low mortality may be a result of improved overall ICU care. We recommend a multi-center, prospective study in future.

Abstract
Sickle cell anemia (SCA) negatively impacts the ability to achieve educational and occupational goals increasing vulnerability to socioeconomic challenges. In a cross-sectional analysis of 332 SCA adults, we investigated whether the distressed community index (DCI) was associated with SCA-related complications and nutritional status. More patients with higher DCI had Medicaid insurance. A higher DCI was independently associated with tobacco use and lower body mass index, serum albumin, and vitamin D 25-OH levels after adjusting for insurance status but was not associated with SCA-related complications. Future studies investigating access to healthy foods may help improve health equity in patients with SCA.

Abstract
OBJECTIVE Sickle cell disease (SCD) is a genetic blood disorder that may affect patients' mood and behavior. However, measuring the prevalence of internalizing symptoms (anxiety and depression) in patients with SCD has been elusive. We assessed internalizing symptoms in adolescents with SCD to evaluate prevalence and to test whether neurocognitive performance and frequency of pain-related episodes were associated with internalizing concerns. METHODS One hundred eighty-five patients (57% HbSS/HbSß0-thalassemia, 43% HbSC/HbSß+-thalassemia), ages 12-18 years, received a neuropsychological evaluation as a part of a larger cohort study. Internalizing symptoms were measured using the Behavior Assessment System for Children, Second or Third Edition. Scores on the depression and anxiety scales were compared to normative values using Wilcoxon signed rank test. Spearman correlations examined associations between neurocognitive performances and internalizing symptoms. Robust multivariable regression models measured associations between internalizing symptoms and age, sex, sickle genotype, total hemoglobin, fetal hemoglobin, socioeconomic status, and frequency of pain episodes. RESULTS Parent- and self-reported ratings of internalizing symptoms were not elevated compared to normative expectations. Overall, 1.8% and 6.3% of the sample displayed clinically elevated symptoms of anxiety and depression based on self-report, respectively. There were no associations between internalizing symptoms and neurocognitive performance (all p > .05). In multivariable analyses, the frequency of pain episodes was positively associated with self-reported anxiety (p = .006) and parent-reported depressive symptoms (p = .017). CONCLUSIONS Adolescents with SCD do not report elevated internalizing symptoms compared to normative expectations. Further research is needed to examine the trajectory of internalizing symptoms and the bidirectional relationship between pain and psychosocial functioning in SCD.

Abstract
BACKGROUND Sickle cell anemia (SCA) is a monogenic hemoglobinopathy associated with severe acute and chronic complications, with the highest incidence worldwide in Sub-Saharan Africa. The wide variability in clinical manifestations suggest that a uniform response to hydroxurea may not be attained. In view of a potential treatment with hydroxyurea (HU), we assessed the variability of clinical and hematological manifestations in a cohort of adults with SCA in Kinshasa, capital of the DR Congo in Central Africa. METHODS A cross-sectional study was conducted in a hospital dedicated to SCA management in Kinshasa. Clinical history of patients was recorded, a complete physical examination performed. The diagnosis was confirmed by means of DNA analysis. A full blood count and hemolysis markers were measured. The severity of the disease was evaluated by means of a previously reported score. RESULTS The study group consisted of 166 genetically confirmed SCA patients. The SCA severity was mild in 28.9%, moderate in 64.5% and severe in 6.6%. The disease severity score increased with patient's age (p ≤ 0.001). The severity was higher in males compared to females (p = 0.012). In males, the severity score was correlated with the presence of priapism (p = 0.045), a manifestation not previously incorporated in the severity score. The severity score was inversely correlated with the fetal hemoglobin (HbF) rate (p = 0.005). Malnutrition (BMI <18.5 kg/m2) was present in 47% of patients and was related to the male sex, hip disease (aOR 3.11; p = 0.019) and severe phenotype (aOR 3.53; p = 0.012). Leg ulcers were more frequent in males than in females (p = 0.001; OR 24.3) and were correlated with the number of days of hospitalization (p = 0.029). Hip disease was related to the increasing age (p = 0.008). CONCLUSION In this selected, hospital-based populations of adults with SCA, severe disease was rare, which may be due to survival bias. However, two thirds had moderate severity of the disease, mostly with a low HbF, and they may benefit from HU treatment. In the Central-African setting the separation between vaso-occlusive and hyperhemolytic sub-phenotypes was not applicable.

Abstract
INTRODUCTION Evidence related to the national burden of Sickle Cell Disease (SCD) in Gulf Cooperation Council (GCC) largely fragmented. Thus, the aim of this study is to systemically review studies from GCC countries to assess the epidemiological profile of SCD. AREAS COVERED We searched combinations of key terms in MEDLINE/PubMed, CINAHL, and EMBASE. We selected relevant observational studies reporting the frequency, incidence, prevalence, risk factors, mortality rate, and complications of SCD among the GCC population. Studies restricted to laboratory diagnostic tests, experimental and animal studies, review articles, case reports and series, and conference proceedings and editorials were excluded. A total of 1,347 articles were retrieved, out of which 98 articles were found to be eligible and included in the study. The total number of participants from all the included studies was 3496447. The prevalence of SCD ranged from 0.24%-5.8% across the GCC and from 1.02%-45.8% for the sickle cell trait. Consanguineous marriage was a risk factor for likely giving children affected with hemoglobinopathies. EXPERT OPINION The prevalence of SCD and its complications vary among GCC. Because of the high prevalence of SCD and its complications, health authorities should focus on more rigorous prevention and treatment strategies.

Abstract
Sickle cell disease (SCD) is an umbrella term for a group of life-long debilitating autosomal recessive disorders that are caused by a single-point mutation (Glu→Val) that results in polymerization of hemoglobin (Hb) and reversible sickle-shape deformation of erythrocytes. This leads to increased hemolysis of erythrocytes and microvascular occlusion, ischemia-reperfusion injury, and tissue infarction, ultimately causing multisystem end-organ complications. Sickle cell anemia (HbSS) is the most common and most severe genotype of SCD, followed by HbSC, HbSβ0thalassemia, HbSβ+thalassemia, and rare and benign genotypes. Clinical manifestations of SCD occur early in life, are variable, and are modified by several genetic and environmental factors. Nearly 500 children with SCD continue to die prematurely every day, due to delayed diagnosis and/or lack of access to comprehensive care in sub-Saharan Africa (SSA), a trend that needs to be urgently reversed. Despite proven efficacy in developed countries, newborn screening programs are not universal in SSA. This calls for a consolidated effort to make this possible, through the use of rapid, accurate, and cheap point-of-care test kits which require minimal training. For almost two decades, hydroxyurea (hydroxycarbamide), a century-old drug, was the only disease-modifying therapy approved by the U.S. Food and Drug Administration. Recently, the list expanded to L-glutamine, crizanlizumab, and voxelotor, with several promising novel therapies in the pipeline. Despite its several limitations, hematopoietic stem cell transplant (HSCT) remains the only curative intervention for SCD. Meanwhile, recent advances in gene therapy trials offer a glimpse of hope for the near future, although its use maybe limited to developed countries for several decades.

Abstract
BACKGROUND Environmental factors seem to influence clinical manifestations of sickle cell disease (SCD), but few studies have shown consistent findings. We conducted a retrospective multicentric observational study to investigate the influence of environmental parameters on hospitalization for vaso-occlusive crises (VOC) or acute chest syndrome (ACS) in children with SCD. METHODS Hospital admissions were correlated with daily meteorological and air-quality data obtained from Environmental Regional Agencies in the period 2011-2015. The effect of different parameters was assessed on the day preceding the crisis up to ten days before. Statistical analysis was performed using a quasi-likelihood Poisson regression in a generalized linear model. RESULTS The risk of hospitalization was increased for low maximum temperature, low minimum relative humidity, and low atmospheric pressure and weakly for mean wind speed. The diurnal temperature range and temperature difference between two consecutive days were determined to be important causes of hospitalization. For air quality parameters, we found a correlation only for high levels of ozone and for low values at the tail corresponding to the lowest concentration of this pollutant. CONCLUSIONS Temperature, atmospheric pressure, humidity and ozone levels influence acute complications of SCD. Patients' education and the knowledge of the modes of actions of these factors could reduce hospitalizations.

OBJECTIVE To understand the psychological and social impact of shielding on people with sickle cell disorders and their carers in the Midlands region of England. This region was badly affected during the pandemic, with the city of Birmingham having some of the highest rates of COVID-19 deaths. DESIGN A mixed-methods project with a quantitative survey on shielding and adapted SF36 V.2 questionnaire, which was supplemented by qualitative semistructured interviews analysed using interpretive phenomenological analysis (IPA). PARTICIPANTS Fifty-one participants who were predominantly of Black Caribbean or Black African heritage anonymously took part in the online survey. We supplemented this with eight in-depth semistructured interviews with adults with sickle cell disorders using IPA. RESULTS The adapted 36-Item Short Form Survey (SF36) version 2 (V. 2) survey indicated worse quality of life and mental health. The open-ended questions from the adapted survey also identified shielding concerns about hospital care, pain management and knowledge of sickle cell by healthcare professionals. From the interviews, it emerged that the racialised element of the pandemic caused significant psychological distress for a population group that had to regularly access hospitals. It was noted that psychological health needs both during a pandemic and outside of it were poorly understood and became invisible in services. The psychological impact of experiences of hospital care as well as growing up with an invisible chronic condition were important to understand psychologically.

Abstract
Sickle cell disease (SCD) is characterized by variable clinical outcomes, with some patients suffering life-threatening complications during childhood, and others living relatively symptom-free into old age. Because of this variability, there is an important potential role for precision medicine, in which particular different treatments are selected for different groups of patients. However, the application of precision medicine in SCD is limited by difficulties in identifying different prognostic groups and the small number of available treatments. The main genetic determinant of outcomes in SCD is the underlying β-globin genotype, with sickle cell anemia (HbSS) and hemoglobin SC disease (HbSC) forming the 2 major forms of the disease in most populations of African origin. Although there are clear differences in clinical outcomes between these conditions, treatments approaches are very similar, with little evidence on how to treat HbSC in particular. Other genomic information, such as the co-inheritance of α-thalassemia, or high fetal hemoglobin (HbF) levels, is of some prognostic value but insufficient to determine treatments. Precision medicine is further limited by the fact that the 2 main drugs used in SCD, penicillin and hydroxyurea, are currently recommended for all patients. Newer treatments, such as crizanlizumab and voxelotor, raise the possibility that groups will emerge who respond best to particular drugs or combinations. Perhaps the best current example of precision medicine in SCD is the selective use of blood transfusions as primary stroke prevention in children with evidence of cerebral vasculopathy. More precise treatments may emerge as we understand more about the pathology of SCD, including problems with erythropoiesis.

Abstract
In this retrospective, we review the two research topics that formed the basis of the outstanding career of Dr. Paul S. Frenette. In the first part, we focus on sickle cell disease (SCD). The defining feature of SCD is polymerization of the deoxygenated mutant hemoglobin, which leads to a vicious cycle of hemolysis and vaso-occlusion. We survey important discoveries in SCD pathophysiology that have led to recent advances in treatment of SCD. The second part focuses on the hematopoietic stem cell (HSC) niche, the complex microenvironment within the bone marrow that controls HSC function and homeostasis. We detail the cells that constitute this niche, and the factors that these cells use to exert control over hematopoiesis. Here, we trace the scientific paths of Dr. Frenette, highlight key aspects of his research, and identify his most important scientific contributions in both fields.

Abstract
Sickle cell disease is a very variable condition, with outcomes ranging from death in childhood to living relatively symptom free into the 8th decade. Much of this variability is unexplained. The co-inheritance of α thalassaemia and factors determining HbF levels significantly modify the phenotype, but few other significant genetic variants have been identified, despite extensive studies. Environmental factors are undoubtedly important, with socio-economics and access to basic medical care explaining the huge differences in outcomes between many low- and high-income countries. Exposure to cold and windy weather seems to precipitate acute complications in many people, although these effects are unpredictable and vary with geography. Many studies have tried to identify prognostic factors which can be used to predict outcomes, particularly when applied in infancy. Overall, low haemoglobin, low haemoglobin F percentage and high reticulocytes in childhood are associated with worse outcomes, although again these effects are fairly weak and inconsistent.

Abstract
The life expectancy of individuals with sickle cell disease has increased over the years, majorly due to an overall improvement in diagnosis and medical care. Nevertheless, this improved longevity has resulted in an increased prevalence of chronic complications such as sickle cell nephropathy (SCN), which poses a challenge to the medical care of the patient, shortening the lifespan of patients by 20-30 years. Clinical presentation of SCN is age-dependent, with kidney dysfunction slowly beginning to develop from childhood, progressing to chronic kidney disease and kidney failure during the third and fourth decades of life. This review explores the epidemiology, pathology, pathophysiology, clinical presentation, and management of SCN by focusing on the pediatric population. It also discusses the factors that can modify SCN susceptibility.

ENVIRONMENTAL RESEARCH 2022; 206:112523. [PMID: 34929187 DOI: 10.1016/j.envres.2021.112523] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Revised: 11/02/2021] [Accepted: 12/04/2021] [Indexed: 06/14/2023]
Abstract
OBJECTIVES Exposure to air pollution is associated with increased risks of several adverse conditions in newborns, such as preterm birth. Whether air pollution is associated with neonatal hyperbilirubinemia remains unclear. We aimed to develop and validate an air-quality-based model to better predict neonatal hyperbilirubinemia. METHODS A multicenter, population-based cohort of neonates with a gestational age (GA) ≥35 weeks and birth weight ≥2000 g was enrolled in the study. The study was conducted in Shanghai, China, from July 2017 to December 2018. The daily average concentrations of particulate matter (PM) with aerodynamic diameters≤2.5 μm (PM2.5) and ≤10 μm (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2) and carbon monoxide (CO) were measured. Neonatal hyperbilirubinemia was diagnosed according to the American Academy of Pediatrics (AAP) guidelines by trained neonatologists. We used logistic least absolute shrinkage and selection operator (LASSO) regression to screen air pollutant indicators related to neonatal hyperbilirubinemia and build an air-quality signature for each patient. An air-quality-based nomogram was then established to predict the risk of neonatal hyperbilirubinemia. RESULTS A total of 11196 neonates were evaluated. Prenatal PM10, CO and NO2 exposure and postpartum SO2 exposure were significantly associated with neonatal hyperbilirubinemia. The air-quality score was calculated according to the hyperbilirubinemia-related pollutants. The air-quality score of the hyperbilirubinemia group was significantly higher than that of the nonhyperbilirubinemia group (P < .01, odds ratio = 2.97). An air-quality-based logistic regression model was built and showed good discrimination (C-statistic of 0.675 [95% CI (confidence interval), 0.658 to 0.692]) and good calibration. Decision curve analysis showed that the air-quality-based model was better than the traditional clinical model in predicting neonatal hyperbilirubinemia. CONCLUSIONS The findings of this study suggest that ambient air pollution exposure is associated with an increased risk of neonatal hyperbilirubinemia. Our results encourage further exploration of this possibility in future studies.

Abstract
Purpose To investigate the feasibility, acceptability, and preliminary efficacy of a 6-session music therapy protocol on self-efficacy, quality of life, and coping skills in adults with sickle cell disease (SCD). Patients and Methods Using a mixed-methods intervention design, adults with SCD (ages 21–57; mean age 32.33) were randomized (1:1) to either 1) a 6-session music therapy (MT) intervention (n = 12) or 2) waitlist control (WLC) (n = 12) using stratified randomization where factors were age in years (≤30 vs >30), and sex (male, female). All participants completed two weeks of daily electronic pain diary entries and self-efficacy, quality of life, and coping skills measures before and after their assigned study condition to explore preliminary efficacy. MT participants were taught music exercises accessed via smartphone and subsequently interviewed to determine feasibility and acceptability. Results The enrollment rate was 89%. All study measures were completed, with high rates of electronic pain diary completion at baseline (70%) and 2-week follow-up (66%). Interviews revealed two overall themes related to MT participants’ experience: 1) participants learned new self-management skills and 2) MT improved participants’ ability to cope with pain. MT participants demonstrated 100% attendance. In preliminary analyses, MT participants demonstrated significant improvements (means ± SD) in self-efficacy (5.42 ± 5.43, p = 0.008, d = 1.20), PROMIS sleep disturbance (−1.49 ± 6.68, p = 0.023, d = −0.99), PROMIS pain interference (−2.10 ± 4.68, p = 0.016, d = −1.06), and ASCQ-Me social functioning impact scores (2.97 ± 6.91, p = 0.018, d = 1.05) compared to WLC participants. Conclusion Preliminary findings support the feasibility and acceptability of music therapy for home use in adults with SCD. While music therapy may assist adults with SCD in improving self-efficacy and quality of life, subsequent, fully-powered clinical research is needed to determine its efficacy. ![]()

Abstract
Background Sickle Cell Disease (SCD) is most common genetic disorder and its prevalence in sub-Saharan Africa is increasing. Despite increased survival rates, experiences of adults living with SCD in Tanzania is not well explored. This article provides perceived causes of pain crisis, pain self-management approaches and psychosocial implication of SCD. Aim This study aimed at exploring experiences of adults living with SCD regarding pain triggering or aggravating factors; self-management for pain; psychosocial-economical implication of SCD and coping mechanism used by individuals living with SCD. Methods A qualitative study design was chosen using in-depth interviews with adults living with SCD to explore their experience of living with SCD. Fifteen adults aged 18 years and above living with SCD were interviewed. Data were analyzed by using content analysis approach. Findings Four categories emerged that described experiences of individuals with SCD. The four categories are; "Pain Triggering and Aggravating Factors" describing participants' perceived factors causing pain in SCD; "Self-care remedies for the pain" referring to participants' methods for self-management of pain; "Psychosocial-economic impact of illness" referring to participants' experience of implication of illness on social and economic life and "Dealing and coping with illness" referring to experience of participants on management and coping strategies used to live with the illness. Conclusion Individuals with SCD experiences several episodes of pain that affect their quality of life. Pain episode can be triggered or aggravated by various factors. Several approaches are used by individuals with SCD to self-manage the pain including taking rest, drinking plenty of water or using pain relieving medication. Care for individuals with SCD should be comprehensive and include proper management of pain, health education on home-based intervention for sickle cell pain, supportive services to deal with psychosocial implications of SCD and improving coping strategies to live with the illness.

Abstract
OBJECTIVES Acute pain is the main complication of sickle cell disease. Chronic pain (CP) and neuropathic pain (NP) may also be experienced, but have not been formally described in Jamaican patients. A cross-sectional study was conducted to determine their prevalence and characteristics, and to determine the common pain locations and modalities of management. MATERIALS AND METHODS All well individuals with sickle cell disease patients 14 years and older, not pregnant and without a history of clinical stroke were consecutively recruited. Anthropometric measurements, hematology studies, an analgesia checklist, and the Adult Sickle Cell Quality of Life Measurement Information System questionnaire were completed. The painDETECT questionnaire was completed to describe NP and pain patterns-from which CP was defined. RESULTS There were 257 patients in total, with 55.6% being females; the mean age of the patients was 31.7±12 years, and 75% had the SS genotype. Almost all patients (92.6%) had had an acute pain crisis in their lifetime and 72.4% in the last year. The mean severity at last attack was 6.8±3.1 on a scale of 0 to 10. The prevalences of CP and NP were 21.5% and 17.9%, respectively. Female sex, the presence of current leg ulcers, and the use of a strong opioid in the last 4 weeks produced higher odds of NP, whereas older age, milder genotypes, and daily analgesic use had the highest odds of CP. Opioids were used by 40.1% of the patients in the previous 4 weeks, whereas nonpharmacological treatments such as physiotherapy was less used, but reported to be very effective. DISCUSSION CP and NP should be assessed during routine care of sickle cell pain so that targeted therapies can be applied.

Abstract
Environmental factors and gene-environment interactions modify the variable expressivity, progression, severity, and onset of some classic (monogenic) Mendelian-inherited genetic diseases. Cystic fibrosis, Huntington disease, Parkinson's disease, and sickle cell disease are examples of well-known Mendelian disorders that are influenced by exogenous exposures. Environmental factors may act by direct or indirect mechanisms to modify disease severity, timing, and presentation, including through epigenomic influences, protein misfolding, miRNA alterations, transporter activity, and mitochondrial effects. Because pathological features of early-onset Mendelian diseases can mimic later onset complex diseases, we propose that studies of environmental exposure vulnerabilities using monogenic model systems of rare Mendelian diseases have high potential to provide insight into complex disease phenotypes arising from multi-genetic/multi-toxicant interactions. Mendelian disorders can be modeled by homologous mutations in animal model systems with strong recapitulation of human disease etiology and natural history, providing an important advantage for study of these diseases. Monogenic high penetrant mutations are ideal for toxicant challenge studies with a wide variety of environmental stressors, because background genetic variability may be less able to alter the relatively strong phenotype driving disease-causing mutations. These models promote mechanistic understandings of gene-environment interactions and biological pathways relevant to both Mendelian and related sporadic complex disease outcomes by creating a sensitized background for relevant environmental risk factors. Additionally, rare disease communities are motivated research participants, creating the potential of strong research allies among rare Mendelian disease advocacy groups and disease registries and providing a variety of translational opportunities that are under-utilized in genetic or environmental health science.

Iliyasu Z, Borodo AM, Jibir BW, Nass NS, Aliyu MH. " A child with sickle cell disease can't live with just anyone." A mixed methods study of socio-behavioral influences and severity of sickle cell disease in northern Nigeria. Health Sci Rep 2021; 4:e222. [PMID: 33376812 PMCID: PMC7757738 DOI: 10.1002/hsr2.222] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 11/11/2020] [Accepted: 11/27/2020] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND The modulatory effects of psychosocial and biophysical environments on sickle cell disease (SCD) severity during childhood has not been well characterized in high burden settings, such as Nigeria. OBJECTIVES We identified socio-demographic correlates and explored caregivers' perceptions on socio-behavioral and environmental influences on hospitalization for pain and blood transfusion of children with SCD in Kano, Nigeria. METHODS Using mixed methods, structured questionnaires were administered to a clinic-based sample of caregivers of children with SCD (n = 372), complemented with eight focus group discussions. Binary logistic regression models and the framework approach were used to analyze the data. RESULTS The majority (73.1%, n = 272) of the children had at least one vaso-occlusive crisis (VOC), and 41.1% (n = 153) required hospitalization in the preceding year. A total of 170 children (45.7%) received blood transfusion. Hospitalization was predicted by the child's age (Adjusted Odds Ratio, AOR = 1.89; 95% Confidence Interval, CI: 1.18-4.07, ≥10 vs <5 years), relationship with caregiver (AOR = 5.41; 95%CI: 1.17-25.05, mother vs "others"), father's number of children (AOR = 2.21; 95%CI: 1.19-5.31, ≥10 vs ≤4), and siblings with SCD (AOR = 2.36; 95%CI: 1.16-8.80, 2 vs 0). Caregivers perceived maternal care, stable home environment, medication adherence, anti-mosquito measures, and adequate nutrition as protective factors, whereas poverty, extreme emotions, physical exertion, and extreme temperatures were identified as detrimental to the health of the child. CONCLUSIONS Hospitalizations for VOC and transfusion rates among children with SCD were high. Understanding the modulatory effects of socio-behavioral factors on SCD severity could inform preventive measures and enhance the quality of life of affected children.

Emotion regulation, pain interference and affective symptoms in children and adolescents with sickle cell disease. J Affect Disord 2021; 282:829-835. [PMID: 33601724 DOI: 10.1016/j.jad.2020.12.068] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Revised: 12/04/2020] [Accepted: 12/20/2020] [Indexed: 11/20/2022]
Abstract
BACKGROUND The ability to regulate emotion is associated with affective disorders and the experience of pain. However, little is known about emotion regulation in youth with Sickle Cell Disease (SCD), a population that regularly experiences pain and symptoms of depression and anxiety. This study examines the relationship between emotion regulation and symptoms of depression, anxiety, and pain interference in youth with SCD. METHODS Participants ages 8-20 at a university-based pediatric sickle cell clinic completed the Emotion Regulation Questionnaire (ERQ) and the Cognitive Emotion Regulation Questionnaire (CERQ), self-report measures assessing use of emotion regulation strategies. Participants also completed the Patient-Reported Outcomes Measurement Information System (PROMIS), measures for symptoms of anxiety, depression, and pain interference. Multiple regression models tested associations between use of emotion regulation strategies and symptoms of depression, anxiety, and pain interference. RESULTS Participants were 51 patients with SCD, 30 female and 21 male, with a mean age of 13.02 years (SD = 0.47, mid-max = 8-20). Use of maladaptive emotion regulation strategies was associated with increased symptoms of depression (r = .58), anxiety (r = .45) and pain interference (r = .30) in youth with SCD. LIMITATIONS Potential limitations of our study include small sample size, use of youth self-report measures, and participant selection contingent on the ability to attend an outpatient appointment. CONCLUSION Identifying maladaptive emotion regulation strategies in youth with SCD may provide clinicians with targeted pathways for improving emotional and psychological functioning.

Abstract
Differences in health outcomes and treatment responses within and between global populations have been well documented. There is growing recognition of the need to move beyond simple inventories and descriptions of these differences and our linear explanations for them, and gain a better understanding of the multifaceted systems and networks underlying them in order to develop more precise and effective remedies. Typical targets for such integrative research have been common multifactorial diseases. We propose sickle cell disease, one of the most common monogenic diseases, as an ideal candidate for elucidating the complexity of the influences of endogenous and exogenous factors on disease pathophysiology, phenotypic diversity, and variations in responses to treatments at both the individual and population levels. We provide data-informed representations of diverse contributors to sickle cell disease complications that could guide innovative efforts to advance scientific knowledge, clinical practice, and policy formulation related to the disease; help improve outcomes for people worldwide with sickle cell disease; and inform approaches to studying and addressing other diseases.

Abstract
Sickle Cell Disease (SCD) is an autosomal recessive disorder resulting from a β-globin gene missense mutation and is among the most prevalent severe monogenic disorders worldwide. Haematopoietic stem cell transplantation remains the only curative option for the disease, as most management options focus solely on symptom control. Progress in prenatal diagnosis and fetal therapeutic intervention raises the possibility of in utero treatment. SCD can be diagnosed prenatally in high-risk patients using chorionic villus sampling. Among the possible prenatal treatments, in utero stem cell transplantation (IUSCT) shows the most promise. IUSCT is a non-myeloablative, non-immunosuppressive alternative conferring various unique advantages and may also offer safer postnatal management. Fetal immunologic immaturity could allow engraftment of allogeneic cells before fetal immune system maturation, donor-specific tolerance and lifelong chimerism. In this review, we will discuss SCD, screening and current treatments. We will present the therapeutic rationale for IUSCT, examine the early experimental work and initial human experience, as well as consider primary barriers of clinically implementing IUSCT and the promising approaches to address them.

Abstract
Pain is a hallmark of Sickle Cell Disease (SCD) affecting patients throughout their life; the first pain crisis may occur at any age and is often the first presentation of the disease. Universal newborn screening identifies children with SCD at birth, significantly improving morbidity and mortality. Without early screening, diagnosis is generally made after disease manifestations appear. The Consortium for the Advancement of Sickle Cell Research (CASiRe) is an international collaborative group evaluating the clinical severity of subjects with SCD using a validated questionnaire and medical chart review, standardized across 4 countries (United States, United Kingdom, Italy and Ghana). We investigated the age of first pain crisis in 555 sickle cell subjects, 344 adults and 211 children. Median age of the first crisis in the whole group was 4 years old, 5 years old among adults and 2 years old among children. Patients from the United States generally reported the first crisis earlier than Ghanaians. Experiencing the first pain crisis early in life correlated with the genotype and disease severity. Early recognition of the first pain crisis could be useful to guide counseling and management of the disease.

Abstract
Sickle Cell Anemia (SCA) is one of the most common monogenic disorders worldwide. Molecular modifiers of clinical symptoms play an essential role in the amelioration of the effects of the disease. Single Nucleotide Polymorphisms (SNPs) of the BCL11A gene and within the HBS1L-MYB intergenic region, which are located outside the β-globin locus on chromosome 11, are considered to be genetic modifiers that are associated with elevated levels of foetal haemoglobin HbF, and thus they reduce the clinical impact of sickle haemoglobin, HbS. The work reported here aimed to detect the most common SNPs of BCL11A and HBS1L-MYB related to HbF in SCA patients and to estimate the frequency of occurrence of these genotypes. A total of 132 SCA patients whose condition was stable were recruited from Jeddah city, Saudi Arabia. SNPs at site locus rs4671393 on BCL11A, and at loci rs28384513 and rs9399137 on HBS1L-MYB were identified using TaqMan genotyping assay. Haematological parameters were analysed based on complete blood count and haemoglobin separation using the capillary electrophoresis technique. Highly significant differences in the diagnostic haematological parameters, including all blood-cell types and HbF, were observed between the study cohort and control groups. We also found that BCL11A rs4671393 genotypes of GG and AG were more likely to show increases in HbF levels than other genotypes. In addition, a strong relationship was found between HBS1L-MYB rs9399137 and rs28384513 genotypes in the cohort, whereas no significant association was observed between BCL11A rs4671393 variant and other variants. Our study highlights the importance of investigating genetic determinants that play roles in the amelioration of the severity of clinical symptoms and complications of SCA.

Abstract
BACKGROUND Sickle cell disease affects a significant portion of US patients with African descent. It continues to be one of the leading causes of frequent hospitalizations and high in-hospital morality risk. Until the approval of disease-modifying therapies in last two years, medical therapy has relied mostly on management of pain episodes and the use of hydroxyurea. We discuss the nationwide analysis of trends in in-hospital mortality in patients with Sickle Cell Disease from 2000 to 2014. METHODS Trends of in-hospital mortality in sickle cell patients were analyzed from a database provided by the Agency of Healthcare Research and Quality. From the data hospitalization rates and in-hospital mortality in categories by region in the US, hospital size, health insurance status, comorbidities and gender were examined. Patterns of in-hospital mortality were analyzed by logistic regression. RESULTS Ratio for hospitalization and mortality among the four regions described Northeast, Midwest, South, West with respective values of 0.63%, 0.65%, 0.76% and 0.89% with P = 0.008 and OR = 1.07. Odds ratio for sickle cell patients that died during hospitalization and health insurance status was OR = 0.08. Comorbidities considered in sickle cell patients; diabetes mellitus (DM), hypertension (HTN), hyperlipidemia (HLD), chronic kidney disease (CKD), smoking status. The odds ratio for comorbidities show A-fib with a value of OR = 4.47, followed by hypertension OR = 1.92, diabetes mellitus OR = 1.44 and chronic kidney disease OR = 1.29, smoking status OR = 0.60. Mortality-hospitalization ratio by gender was: males 0.77% and females 0.69% with OR = 0.87. CONCLUSIONS In-hospital mortality by US regions, as well as health insurance status are important measurable elements that show the impact of the disease from a public health perspective. Further and more specific data of regions by states, comorbidities by states and sex, as well as health insurance status by states will provide further insight in local mortality trends.

Abstract
Persons with sickle cell disease (SCD) exhibit subjective hypersensitivity to cold and heat perception in experimental settings, and triggers such as cold exposure are known to precipitate vaso-occlusive crises by still unclear mechanisms. Decreased microvascular blood flow (MBF) increases the likelihood of vaso-occlusion by increasing entrapment of sickled red blood cells in the microvasculature. Because those with SCD have dysautonomia, we anticipated that thermal exposure would induce autonomic hypersensitivity of their microvasculature with an increased propensity toward vasoconstriction. We exposed 17 patients with SCD and 16 control participants to a sequence of predetermined threshold temperatures for cold and heat detection and cold and heat pain via a thermode placed on the right hand. MBF was measured on the contralateral hand by photoplethysmography, and cardiac autonomic balance was assessed by determining heart rate variability. Thermal stimuli at both detection and pain thresholds caused a significant decrease in MBF in the contralateral hand within seconds of stimulus application, with patients with SCD showing significantly stronger vasoconstriction (P = .019). Furthermore, patients with SCD showed a greater progressive decrease in blood flow than did the controls, with poor recovery between episodes of thermal stimulation (P = .042). They had faster vasoconstriction than the controls (P = .033), especially with cold detection stimulus. Individuals with higher anxiety also experienced more rapid vasoconstriction (P = .007). Augmented vasoconstriction responses and progressive decreases in perfusion with repeated thermal stimulation in SCD are indicative of autonomic hypersensitivity in the microvasculature. These effects are likely to increase red cell entrapment in response to clinical triggers such as cold or stress, which have been associated with vaso-occlusive crises in SCD.

Abstract
Purpose
This paper aims to examine the role of information and communication technology (ICT) in the knowledge creation practices adopted by a health care organization. The organization is delivering care to patients of a genetic disorder, called the sickle cell, in tribal communities. The paper identifies how ICT intermediates knowledge creation practices across the organizational boundaries wherein tribal patients, front-line counselors and expert physicians interact, which then produces context-specific, evidence-based medicine (EBM).
Design/methodology/approach
The knowledge-in-practice approach is adopted to conduct an ethnographic study of sickle cell care practices in a non-profit health care organization in Western India. The analysis focuses on ICT-mediated interactional practices among the physicians, front-line counselors, tribal patients and their families, for more than a year-long observation. These are supplemented with informal and formal interviews, archival records and vignettes based on several episodes to explicate the key knowledge creation practices.
Findings
Technology-mediated informative interactions at organizational boundaries can bridge socio-linguistic and interpretive barriers between actors, while also providing a generative structure that leads to the creation of longitudinal clinical evidence about a rare genetic disorder. Three specific ICT-entwined knowledge creation practices emerge, namely, knowing the community, increasing interactional engagement and constructing gradients of socio-clinical history. These practices generate organization-wide knowledge about the social and clinical dimensions of the genetic disorder. The findings are presented through vignettes and a novel conceptual framework.
Research limitations/implications
This study identifies various useful knowledge creation practices in health care delivery for resource-constrained emerging economy contexts. Further, the study suggests that the involvement of local front-line actors and ICT can become important resources in the delivery of health care in these settings.
Originality/value
A novel framework is developed which demonstrates knowledge creation at organizational boundaries wherein the actors use ICT-based practices for effective delivery of health care. The proposed framework may be used by health care organizations in similar contexts providing care to marginalized communities.

Objective: To test the hypothesis that caregivers' or adult participants' low ratings of provider communication are associated with more hospital admissions among adults and children with sickle cell disease (SCD), respectively. Secondarily, we determined whether there was an association between the caregivers' or participants' health literacy and rating of providers' communication. Methods: Primary data were collected from participants through surveys between 2014 and 2016, across six sickle cell centers throughout the U.S. In this cross-sectional cohort study, 211 adults with SCD and 331 caregivers of children with SCD completed surveys evaluating provider communication using the Consumer Assessment of Healthcare Providers and Systems (CAHPS), healthcare utilization, health literacy, and other sociodemographic and behavioral variables. Analyses included descriptive statistics, bivariate analyses, and logistic regression. Results: Participants with better ratings of provider communication were less likely to be hospitalized (odds ratio (OR) = 0.54, 95% confidence interval (CI) = [0.35, 0.83]). Positive ratings of provider communication were associated with fewer readmissions for children (OR = 0.23, 95% CI = [0.09, 0.57]). Participants with better ratings of provider communication were less likely to rate their health literacy as lower (regression coefficient (B) = -0.28, 95% CI = [-0.46, -0.10]). Conclusions: Low ratings of provider communication were associated with more hospitalizations and readmissions in SCD, suggesting the need for interventions targeted at improving patient-provider communication which could decrease hospitalizations for this population.

Sickle cell disease clinical phenotypes in Nigeria: A preliminary analysis of the Sickle Pan Africa Research Consortium Nigeria database. Blood Cells Mol Dis 2020; 84:102438. [PMID: 32504882 DOI: 10.1016/j.bcmd.2020.102438] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Revised: 04/07/2020] [Accepted: 04/07/2020] [Indexed: 11/20/2022]
Abstract
BACKGROUND/OBJECTIVE Sickle cell disease (SCD) is a monogenic disease with multiple phenotypic expressions. Previous studies describing SCD clinical phenotypes in Nigeria were localized, with limited data, hence the need to understand how SCD varies across Nigeria. METHOD The Sickle Pan African Research Consortium (SPARCO) with a hub in Tanzania and collaborative sites in Tanzania, Ghana and Nigeria, is establishing a single patient-consented electronic database with a target of 13,000 SCD patients. In collaboration with the Sickle Cell Support Society of Nigeria, 20 hospitals, with paediatric and adult SCD clinics, are participating in patient recruitment. Demographic and clinical information, collected with uniform case report forms, were entered into Excel spreadsheets and uploaded into Research Electronic Data Capture software by trained data clerks and frequency tables generated. RESULT Data were available on 3622 patients enrolled in the database, comprising 1889 (52.9%) females and 1434 (39.6%) children ≤15 years. The frequencies of Hb SS, Hb SC and Hb Sβ thalassemia in this data set were 97.5%, 2.5% and 0% respectively. Sixty percent, 23.8%, 5.9%, 4.8% and 2.5% have had bone pain crisis, dactylitis, acute chest syndrome, priapism and stroke respectively. The most frequent chronic complications were: leg ulcers (6.5%), avascular necrosis of bone (6.0%), renal (6.3%) and pulmonary hypertension (1.1%). Only 13.2% had been hospitalized while 67.5% had received blood transfusion. CONCLUSION These data on the spectrum of clinical phenotypes of SCD are useful for planning, improving the management of SCD across Nigeria and provide a foundation for genomic research on SCD.

Abstract
BACKGROUND Sickle cell disease (SCD) is an inherited, autosomal recessive blood disorder, among the most prevalent genetic diseases, globally. While the genetic and hemolytic dynamics of SCD have been well-characterized, the etiology of SCD-related pathophysiological processes is unclear. Although limited, observational evidence suggests that environmental factors, including urban air pollution, may play a role. OBJECTIVES We assessed whether daily ambient air pollution concentrations are associated with corresponding emergency department (ED) visit counts for acute SCD exacerbations in Atlanta, Georgia, during a 9-year (2005-2013) period. We also examined heterogeneity in response by age and sex. METHODS ED visit data were from 41 hospitals in the 20-county Atlanta, GA area. Associations between daily air pollution levels for 8 urban air pollutants and counts of SCD related ED visits were estimated using Poisson generalized linear models. RESULTS We observed positive associations between pollutants generally indicative of traffic emissions and corresponding SCD ED visits [e.g., rate ratio of 1.022 (95% CI: 1.002, 1.043) per interquartile range increase in carbon monoxide]. Age stratified analyses indicated stronger associations with traffic pollutants among children (0-18 years), as compared to older age strata. Associations involving other pollutants, including ozone and particulate matter and for models of individuals >18 years old, were consistent a null hypothesis of no association. DISCUSSION This analysis represents the first North American study to examine acute risk among individuals with SCD to urban air pollution and provide evidence of urban air pollution, especially from traffic sources, as a trigger for acute exacerbations. These findings are consistent with a hypothesis that biological pathways, including several centrally associated with oxidative stress, may contribute towards enhanced susceptibility in individuals with SCD.

Abstract
Objective: To use the spatial distribution of the sickle cell trait (SCT) to analyze
the frequency of hemoglobin S (HbS) carriers in Sergipe. Methods: The sample consisted of all individuals born in Sergipe from October 2011 to
October 2012 who underwent neonatal screening in the public health system.
Tests were carried out in basic health units and forwarded to the University
Hospital laboratory, where they were analyzed. We used spatial
autocorrelation (Moran’s index) to assess the spatial distribution of
heterozygous individuals with hemoglobinopathies. Results: Among 32,906 newborns, 1,202 showed other types of hemoglobin besides
Hemoglobin A. We found a positive correlation between the percentage of
black and multiracial people and the incidence of SCT. Most SCT cases
occurred in the cities of Aracaju (n=273; 22.7%), Nossa Senhora do Socorro
(n=102; 8.4%), São Cristóvão (n=58; 4.8%), Itabaiana (n=39; 4.2%), Lagarto
(n=37; 4.01%), and Estância (n=46; 4.9%). Conclusions: The spatial distribution analysis identified regions in the state with a
high frequency of HbS carriers. This information is important health care
planning. This method can be applied to detect other places that need health
units to guide and care for sickle cell disease patients and their
families.

Abstract
OBJECTIVE Sickle Cell Disease (SCD) is an inherited blood disorder that includes acute pain episodes and chronic pain that can dramatically impact quality of life and goal-achievement. Our staff had limited success in connecting families with the Pain, Palliative Care and Integrative Medicine Clinic (PPCIM) to receive specialized skills for pain management. We created a partnership between Hematology and PPCIM to provide SCD patients/families with needed resources. DESIGN/SETTING In 2016, key stakeholders collaborated to create a Sickle Cell Wellness Clinic (SCWC) clinic to provide families access to integrative medicine and wellness strategies. Design/structure, based on family focus group data and staff expertise, included a half-day, 7-discipline clinic housed in the PPCIM space. Patients with SCD, ages 8-20, learned strategies in an effort to improve health care utilization and increase overall quality of life. MAIN OUTCOME MEASURES/RESULTS Feedback from two successful pilot clinics in 2017 was incorporated into the formal roll-out of SCWC in 2018. SCWCs continued monthly for one year, serving a total of 20 families post-pilot. SCD patients increased follow-up appointment engagement in the PPCIM clinic following SCWC and reported high levels of satisfaction with their healthcare experience. CONCLUSIONS It is feasible to run a multidisciplinary clinic focused on pain management, coping skills, and healthy living with SCD. Providers benefited from the opportunity to collaborate with other disciplines. Patient and family feedback was positive, highlighted benefits of being introduced to new modalities, and reported advantages of meeting other patients/families in a new setting.

Abstract
Background Sickle cell disease (SCD) is an inherited blood disorder that affects red blood cells. (SCD) is characterized by recurrent vaso-occlusive crisis (VOC). Material and methods This was a descriptive cross sectional study conducted through the period from July 2015 to July 2017 in which a total of seventy two blood specimens were collected in ‘EDTA’ and citrated vacutainers from Sudanese patients with SCD attending “Fath Elrhman Albasheer” Centre. Both sexes' with different ages were included. Among these samples 49 (68.1%) were in steady state while the remained 23 (31.9%) were in VOC. All samples were tested for coagulation profile Result There was increase in fibrinogen and D-dimer levels in most patients 67% and 71%, respectively. Significant increase in D-dimers was observed in patients with (VOC) compared with steady state (P. value = 0.006). Protein S was significantly increased in males in comparison with females P. value = 0.017. The results of prothrombin time (PT), international normalized ratio (INR) and thrombin time (TT) were within normal range. Conclusion Significant increase in levels of D-dimer during VOC indicating abnormal coagulation and fibrinolysis activation. Reduced levels of natural anticoagulants proteins C and S can be consider as predictive markers indicate hepatic dysfunction in patients with SCD.

Abstract
Background: The inherent characteristics of the sickle cell disease (SCD), the most common genetic hematological disorder, increase the propensity of infections. Bartonella spp. are emerging and neglected bacteria. A large spectrum of clinical manifestations has been linked to bartonella bloodstream infection in the last two decades that can cause fatal outcomes, especially in immunodeficient patients. The goal of this study was to evaluate the prevalence of bartonella infection in SCD patients. Materials and Methods: We evaluated Bartonella spp. prevalence in 107 SCD patients. Blood samples and enrichment blood cultures were analyzed by molecular detection of Bartonella spp. DNA. Bartonella DNA was amplified using conventional genus-specific Bartonella PCR which amplifies the Intergenic Transcribed Spacer region and Bartonella henselae-specific nested PCR which amplifies the FtsZ gene. Positive patient DNAs were tested with ssrA conventional PCR. All amplicons were sequenced. Findings: Ten of 107 patients tested positive for B. henselae infection in at least one molecular test. All obtained amplicons were sequenced and similar to B. henselae sequences deposited in GenBank (accession number BX897699). Based on statistical results, bloodstream infection with B. henselae was not associated with animal contact or blood transfusions. Conclusion: We detected B. henselae DNA in 10 (9.3%) SCD studied patients. These patients were notified and treatment was offered to them.
