Archaeological Survey of the Outer Islands of the Gulf of Finland in 2019

In 2019, an expedition of the Institute for the History of Material Culture (IIMK) RAS conducted archaeological surveys on the following islands in the archipelago of Vneshniye Ostrova (Outer Islands, Finnish: Suomenlahden ulkosaaret) in the Gulf of Finland: Moshchny Island (Lavansaari), Maly (Peninsaari), Seskar (Seiskari) and Yuzhny Virgin (Itä-Viiri). Familiar sites were re-examined and new ones were revealed. On Moshchny Island, a cairn, a burial ground, a Bronze Age – Early Iron Age settlement, a stone foundation of a church of the Modern Period and a group of stone heaps were discovered. On Yuzhny Virgin island, stone structures including labyrinths, circles and heaps of stone were examined. The studied sites are culturally close to the antiquities of the northern littoral of the Gulf of Finland (the Vyborg region of Leningrad oblast and southeastern Finland)

Anaphylaxis: incidence, presentation, causes and outcome in patients in a tertiary care hospital in Karachi, Pakistan

Background: Anaphylaxis is a potentially fatal condition requiring immediate resuscitation. Data regarding the epidemiology of anaphylaxis are limited and inconsistent. A reason for the variability was unavailability of a universally acceptable case definition till 2005. We reviewed cases using this new definition Aim: To review the incidence, clinical presentation, cause and outcome of anaphylaxis at a tertiary care center in a low income country. Design: Retrospective, case series Methods: Chart review of all patients discharged from Aga Khan University Hospital between January 1988 - December 2012 (24 years) with anaphylaxis definition as per second National Institute of Allergy and Infection disease/Food Allergy and Anaphylaxis Network Symposium Results: Total of 129 cases were found with mean age of 41.6 years (SD 18.8). Majority of patients had cutaneous features (76.7 %), followed by respiratory (68.9 %), cardiac (64.3 %) and gastrointestinal (20.9 %) symptoms respectively. About 22.4 % of patients had positive history for allergens out of which 31% (n=9) were exposed to the same allergens. The common causes identified for anaphylaxis were drugs (60.5 %), food (16.3 %) and intravenous contrast (10.9 %) respectively. Only 22.5 % of cases received epinephrine as part of their initial management. In 4 patients (3.1 %) the cause of death was attributed to anaphylaxis. Conclusion: Anaphylaxis is a rare but life threatening condition. Though cutaneous features are most common, their absence does not exclude the diagnosis. Drugs were the most common cause and epinephrine was not commonly used as first line agent for its management

Average out-of-pocket healthcare and work-loss costs of traffic injuries in Karachi, Pakistan

The objective of this study was to assess the average out-of-pocket healthcare and work-loss costs of road traffic injuries (RTI) in Karachi. In this cross-sectional study, RTI Patients presenting to the five trauma centres in Karachi were contacted using stratified sampling to report their inPatient and outPatient expenses, the time spent in hospital and their average monthly income. These costs were compared among different categories of Patient-related variables using analysis of variance test. Out of 341 RTI victims, two wheelers accounted for the majority of injuries (77.2%, N=256) followed by pedestrians (14.2%, N=48). Almost half of the sample Patients were breadwinners (N=135, 45.2%), with 87.4% (N=118) earning less than US$248. Average out-of-pocket healthcare costs were US$ 271 (SD=440.9), which were significantly higher (P ≤ 0.026) for pedestrians (US$442), moderate (US$ 341.7) or severe (US$553.8) injury, and treatment in private hospitals (US$ 451.7). Similarly, average work loss was US$67.1 (SD=132.1), which were significantly higher (P=0.001) for breadwinners (US$ 99.1), moderate (US$130.0) or severe (US$ 157.1) injury, and treatment in private hospitals (US$ 150.0). Study results clearly showed the need to advocate RTI prevention measures in Pakistan as any such event could lead to a difficult economic situation for those involved and their family

Mortality rate in children caused by traffic accidents according to geographical regions : Brazil, 1997 - 2005 Mortalidade de crianças por acidente de trânsito segundo região geográfica : Brasil, 1997 a 2005

Fatal injuries in children caused by motor vehicle accidents represent a common situation in many countries worldwide. The present study addresses the mortality rate in children as vehicle passengers in Brazil, from 1997 to 2005. To evaluate mortality rates, the number of deaths was collected from the National Mortality Information System (SIM) and the population size was obtained using the Brazilian Bureau Census (IBGE) data available at DATASUS. Mortality rates were estimated in three-year periods and analyzed according to age groups (younger than 1 year old, 1-4 years old, 5-9 years old) and geographical regions using a 95% confidence interval. Overall results showed mortality rates of 5.68, 7.32 and 6.78 (per 1,000,000) for the 1997-1999, 2000-2002 and 2003-2005 periods, respectively for the whole country. Children younger than 1 year old had a mortality rate of 10.18 (per 1,000,000), which was higher than for the other age groups. For the period analyzed, the highest rates were observed for the Mid-West and South regions of Brazil, with rates of 13.88 and 11.47 (per 1,000,000), respectively. These results show the risk of fatal injury in children caused by motor vehicle accidents and may contribute to the establishment of educational campaigns aiming injury prevention in children as vehicle passengers.<br>Lesões fatais em crianças causadas por acidentes de trânsito representam um problema em muitos países. Este estudo analisou a taxa de mortalidade em crianças passageiras de automóveis menores de 10 anos de idade no Brasil, entre 1997 e 2005. Para isso, o número de mortes foi obtido diretamente no banco de dados do Sistema de Informação sobre Mortalidade (SIM) e os dados da população são projeções intercensitárias a partir censo demográfico do Instituto Brasileiro de Geografia e Estatística (IBGE) disponíveis pelo site do DATASUS. Foram calculadas, para os triênios compreendidos no período em estudo, as taxas de mortalidade por acidente de trânsito entre crianças passageiras de automóveis segundo faixa etária (menor que 1 ano, 1 a 4 e 5 a 9) e região geográfica. Os resultados mostraram taxas de mortalidade de 5,68, 7,32 e 6,78 (por 1.000.000), respectivamente, para os períodos 1997-1999, 2000-2002 e 2003-2005 para todo o Brasil. Crianças menores de 1 ano de idade apresentam taxa de mortalidade de 10,18 (por 1,000,000), maior que as observadas para as outras faixas etárias. Para o período 1997-2005, as maiores taxas foram observadas nas regiões Centro-Oeste e Sul, representando, respectivamente, 13,88 e 11,47 (por 1.000.000). Tais resultados mostram a situação de risco da criança em relação a acidentes de trânsito como passageiras de automóveis e contribuem para a elaboração de campanhas educativas de prevenção de lesões

The Arrival of Siberian Ancestry Connecting the Eastern Baltic to Uralic Speakers further East

In this study, we compare the genetic ancestry of individuals from two as yet genetically unstudied cultural traditions in Estonia in the context of available modern and ancient datasets: 15 from the Late Bronze Age stone-cist graves (1200-400 BC) (EstBA) and 6 from the Pre-Roman Iron Age tarand cemeteries (800/500 BC-50 AD) (EstIA). We also included 5 Pre-Roman to Roman Iron Age Ingrian (500 BC-450 AD) (IngIA) and 7 Middle Age Estonian (1200-1600 AD) (EstMA) individuals to build a dataset for studying the demographic history of the northern parts of the Eastern Baltic from the earliest layer of Mesolithic to modern times. Our findings are consistent with EstBA receiving gene flow from regions with strong Western hunter-gatherer (WHG) affinities and EstIA from populations related to modern Siberians. The latter inference is in accordance with Y chromosome (chrY) distributions in present day populations of the Eastern Baltic, as well as patterns of autosomal variation in the majority of the westernmost Uralic speakers [1-5]. This ancestry reached the coasts of the Baltic Sea no later than the mid-first millennium BC; i.e., in the same time window as the diversification of west Uralic (Finnic) languages [6]. Furthermore, phenotypic traits often associated with modern Northern Europeans, like light eyes, hair, and skin, as well as lactose tolerance, can be traced back to the Bronze Age in the Eastern Baltic.

Recovery course of persistent posterior subretinal fluid after successful repair of rhegmatogenous retinal detachment

Purpose To investigate best corrected visual acuity (BCVA), subretinal fluid (SRF) absorption time or ellipsoid zone (EZ) restoration time and various variables in patients with persistent SRF after successful primary repair of rhegmatogenous retinal detachment (RRD). Methods This retrospective multicenter study allowed independent analysis of the healing pattern by two observers based on composite of serial cross-sectional macular optical coherence tomography (OCT) scans. Univariate and multivariate analyses were implemented. Results One hundred and three cases had persistent SRF after pars plana vitrectomy, scleral buckling, or pneumatic retinopexy. By univariate analysis, SRF resolution time correlated positively with the number of retinal breaks ( p < 0.001) and with increased myopia ( p = 0.011). Using multivariate analysis, final BCVA (log MAR) correlated positively with age, duration of RRD, initial BCVA (OR = 3.28; [95%CI = 1.44–7.47]; p = 0.015), and SRF resolution time (OR = 0.46 [95%CI 0.21–1.05]; p = 0.049). EZ restoration time was longer with increasing number of retinal tears (OR = 0.67; [95%CI 0.29–1.52]; p = 0.030), worse final BCVA, and presence of macula-off RRD (OR = 0.26; [95%CI 0.08–0.88]; p = 0.056). SRF resolution time correlated marginally with prone position. Conclusions Residual posterior SRF is more common in eyes with multiple breaks or in myopic eyes. Final BCVA is better in younger subjects and in eyes with shorter duration of RRD. Persistent SRF is a self-limited disorder with a mean resolution of 11.2 months with good visual prognosis improving from a mean baseline logMAR of 1.08 to 0.25 at one year
