Epidemiological Characteristics

Background: Strongyloidiasis is a parasitic disease with global prevalence. In Spain, autochthonous cases are concentrated in the Mediterranean basin. We aimed to analyze clinical and epidemiological characteristics of Strongyloides stercoralis infection in Vega Baja del Segura (Spain), comparing autochthonous versus imported cases. Methods: Observational retrospective study of all strongyloidiasis cases from January 2009 to January 2019. Cases were diagnosed by stool larvae visualization, positive culture, PCR, Strongyloides serology, and/or compatible histology. Results: We included 36 patients (21 men) with a mean age of 60.8 years ±17.6; 15 cases were autochthonous and 21 imported 80.9% from Latin America. Autochthonous cases were associated with older age (mean 71.3 vs. 53.3 years; p = 0.002), male sex (odds ratio (OR) 5.33; 95% confidence interval (CI) 1.15–24.68; p = 0.041), and agricultural activity (OR 13.5; 95% CI 2.4–73.7; p = 0.002). Fourteen were asymptomatic, three autochthonous cases presented with hyperinfection syndrome, and two patients died. There was no difference between autochthonous versus imported origin in eosinophilia at diagnosis (93.3% vs. 75%; p = 0.207), treatment received, or clinical response (85.7% vs. 88.9% cured; p = 1). Conclusion: In our region, imported strongyloidiasis coexists with autochthonous cases, which are mainly in older male farmers who are diagnosed at more advanced stages. Systematic screening programs are needed.

AbstractObjectivesgiven the scarcity of data regarding prevalence of various infectious diseases in Latin-American countries, our study aims to assess the burden of T.cruzi, S.stercoralis, HIV and viral hepatitis in Latin-American migrants, with a focus on Bolivian migrants.Methodswe performed a retrospective observational study of 565 screening evaluations on adults (≥ 18 years) carried out at our referral International Healthcare service in Barcelona. We reviewed structured clinical records and microbiological results of patients attended between February 2012 and April 2015.Resultsthe median 35 years old and 74% were women. Bolivian origin accounted for 87% of the screened population. We found a 48% prevalence of T.cruzi, 16% of S.stercoralis, 0.2% of HIV, 92% of HAV, 0.2% HBV and 0.2% HCV.Conclusionsthese results support the relevance of the screening of T. cruzi and S. stercoralis in Bolivian migrants, but challenge the pertinence of systematic screening of HBV in this population.Author summaryIn response to the challenge of detecting diseases not previously present in host countries, screening programs have been implemented for migrants based on the probability of having certain diseases depending on their country of origin and / or migratory route. This increased risk is very clearly established in some cases such as Trypanosoma cruzi infection (the cause of Chagas disease) in people from Latin America; especially from Bolivia. In recent years screening recommendations for Strongyloides stercoralis in this population was proven necessary. Current recommendations regarding systematic screening for hepatitis B establish the relevance of screening based on the probability of the disease in the 2% population of origin. Since there are no reliable and up to date data regarding prevalence of hepatitis B virus in Bolivia, we aimed to analyze data available for migrants from Bolivia in Spain.Our results support the importance of screening for T. cruzi and S.stercoralis in patients from Bolivia. However, our data show a much lower prevalence of this hepatitis B virus (0.2%) than the 2% threshold that would justify systematic screening, so we question the relevance of screening for hepatitis B virus in this population in the absence of other risk factors.

Abstract Background The present study aims to provide a comparative analysis of the etiologies of female infertility between Dehong, on the Yunnan Frontier, and Kunming. Methods A retrospective study, which included 941 infertile females in Kunming who were treated in the First People’s Hospital of Yunnan Province and infertile females who were treated in the local hospital in Dehong from January 2016 to November 2018, was conducted. A comparative analysis of the etiologies of infertility in the two regions was then carried out. Results In patients with primary infertility, ovulation disorder (15.03%) was the main cause of infertility in Kunming, and pelvic inflammatory disease (25.59%) was the main cause in Dehong. With regard to secondary infertility, although pelvic inflammatory disease was the main cause of infertility in both regions, the incidence of intrauterine adhesions in Kunming was significantly higher than in Dehong. Conclusions The etiology of infertility showed different epidemiological characteristics depending on the region, hence individualized treatment should be given accordingly

Abstract Background: Traumatic Brain Injury (TBI) which is the leading cause of morbidity and mortality all over the world and the impact is much worse in Pakistan. The objective of the study is to describe the epidemiological characteristics of patients with TBI in our country and to determine the immediate outcomes of patients with TBI after the presentation.Method: This retrospective study was conducted at the Lady Reading Hospital. Data were extracted from the medical record room from January 1st to December 31st, 2019. The severity of TBI was based on Glasgow Coma Scale (GCS) and was divided into mild (GCS 13-15), moderate (GCS 9-12), and severe TBI (GCS <8) based on the GCS. SPSS v.23 was used for data analysis. Results: Out of 5047 patients, 3689 (73.1%) males and 1358 (26.9%) females. The most commonly affected age group was 0-10 years (25.6%) and 21-30 years (20.1%). was the predominant cause of injury (38.8%, n=1960) followed by fall (32.7%, n=1649). Most (93.6%, n=4710) of the TBIs were mild. After the full initial assessment and workup, and completing all first-aid management, the immediate outcome was divided into four, most frequent (67.2%, n=3393) of which was “disposed (discharged)”, and 9.3% (n=470) were admitted for further management.Conclusion: Our study represents a relatively conclusive picture of epidemiological data on the burden of TBI in Pakistan. Although a large proportion of patients had a mild TBI, they may likely be under-diagnosed. This warrants for further investigation of MTBI in population-based studies across the globe.

Background Heterogeneity and focalization are the most common epidemiological characteristics of endemic countries in the Americas, where malaria transmission is moderate and low. During malaria elimination, the first step is to perform a risk stratification exercise to prioritize interventions. This study aimed to identify malaria risk strata in the ecoepidemiological regions of Colombia. Methods This was a descriptive and retrospective study using cumulative malaria cases in 1,122 municipalities of Colombia from 2010 to 2019. To identify the strata, the criteria proposed by PAHO were adapted. To classify the receptive areas (strata 2, 3, and 4) and nonreceptive areas (stratum 1), 1,600 m above sea level, ecotypes, main malaria vector presence, Plasmodium species prevalence and occurrence of malaria cases were used. The area occupied by the receptive municipalities, the cumulative burden, and the at-risk population in the regions were calculated. Results Ninety-one percent of the Colombian territory is receptive to the transmission of malaria and includes 749 municipalities with 9,734,271 (9,514,243–9,954,299) million at-risk inhabitants. Stratum 4 accounted for 96.7% of the malaria burden, and cases were concentrated primarily in the Pacific and Uraba-Bajo Cauca-Sinu-San Jorge regions. Plasmodium vivax predominates in most of the receptive municipalities, except in the municipalities of the Pacific region, where P. falciparum predominates. Anopheles albimanus, An. nuneztovari s.l., and An. darlingi were the main vectors in receptive areas. Conclusions In Colombia, 91.2% of the territory is receptive to the transmission of malaria and is characterized by being both heterogeneous and focused. Stratum 4 contains the greatest burden of disease, with a relatively greater proportion of municipalities with a predominance of P. vivax. However, there is a low proportion of municipalities with P. falciparum mainly in the Pacific region. These findings suggest that the latter be prioritized within the malaria elimination plan in Colombia.

SummaryBackgroundSARS-CoV-2 has been a global pandemic, but the emergence of asymptomatic patients has caused difficulties in the prevention of the epidemic. Therefore, it is significant to understand the epidemiological characteristics of asymptomatic patients with SARS-CoV-2 infection.MethodsIn this single-center, retrospective and observational study, we collected data from 167 patients with SARS-CoV-2 infection treated in Chongqing Public Health Medical Center (Chongqing, China) from January to March 2020. The epidemiological characteristics and variable of these patients were collected and analyzed.Findings82.04% of the SARS-CoV-2 infected patients had a travel history in Wuhan or a history of contact with returnees from Wuhan, showing typical characteristics of imported cases, and the proportion of severe Covid-19 patients was 13.2%, of which 59% were imported from Wuhan. For the patients who was returnees from Wuhan, 18.1% was asymptomatic patients. In different infection periods, compared with the proportion after 1/31/2020, the proportion of asymptomatic patient among SARS-CoV-2 infected patient was higher(19% VS 1.5%). In different age groups, the proportion of asymptomatic patient was the highest(28.6%) in children group under 14, next in elder group over 70 (27.3%). Compared with mild and common Covid-19 patients, the mean latency of asymptomatic was longer (11.25 days VS 8.86 days), but the hospital length of stay was shorter (14.3 days VS 16.96 days).ConclusionThe SARS-CoV-2 prevention needs to focus on the screening of asymptomatic patients in the community with a history of contact with the imported population, especially for children and the elderly population.

Abstract Background Dengue is the most prevalent mosquito-borne disease in the world, with China affected seriously in recent years. 65.8% of dengue cases identified in mainland China since 2005 were reported from the city of Guangzhou. Methods In this study, we described the incidence rate and distribution of dengue cases using data collected form National Notifiable Infectious Disease Reporting Information System data in Guangzhou for 2001 to 2016. All dengue cases were investigated using standardized questionnaire. Results A total of 42,469 dengue cases were reported, with an average annual incidence rate of 20.99 per 100,000 resident population. Over this time period, the incidence rate of indigenous cases increased. Dengue affected areas also expanded sharply geographically from 58.1% of communities affected during 2001–2005 to 96.4% of communities affected in 2011–2016. Overall 95.30% of the overseas imported cases were reported during March and December, while 99.79% of indigenous cases were reported during July and November. All four dengue virus serotypes were identified both in imported cases and indigenous cases. The Aedes albopictus mosquito was the only vector for dengue transmission in the area. Conclusions Guangzhou has become the dengue epicenter in mainland China. Control strategies for dengue should be adjusted to the epidemiological characteristics above and intensive study need to be conducted to explore the factors that driving the rapid increase of dengue.

1 A 5-year retrospective study of 1743 episodes of self-poisoning in 1608 adult patients, was undertaken to determine the frequency of self-poisoning with psychopharmacological agents, the frequency of each toxic agent usage and the epidemiological characteristics of the poisoned population. 2 The annual incidence of self-poisoning in Zagreb was 38.7 per 100 000 adult inhabitants. The anxiolytic-antipsychotic-antidepressant usage ratio was 8.8:1.5:1.0 in total self-poisoning, whereas it was 4.9:1.5:1.0 in patients with a previous history of self-poisoning. The use of anxiolytics decreased and the use of antidepressants increased during the 5 years. 3 The female—male ratio was 3.8:1 and 77% of self-poisoned persons were aged 15-44 years. The incidence of self-poisoning was 74% higher in the urban than in the rural population. The proportion of self-poisoned persons was 204% higher among the unemployed than in the population as a whole. There were 76% more repetitors among highly educated and 43% fewer repetitors among students than in the general population. The use of antipsychotics was 120% higher in males than in females. The use of antidepressants was 107% higher in the highly educated. 4 The increased use of antidepressants in self-poisoning is an alarming signal and caution in their prescription seems to be indicated.
