Published: February 2023

Kutu merupakan serangga ektoparasit yang ditemukan pada burung, mamalia dan bahkan manusia. Pada burung kutu biasanya berkumpul di bagian dada, paha dan sayap. Spesies kutu yang berada pada tubuh merpati dapat berbeda. Identifikasi morfologi dan molekular digunakan untuk menentukan spesies makhluk hidup tertentu, temasuk kutu. Tujuan studi ini yaitu mengidentifikasi kutu pada merpati secara morfologi dan molekular. Identifikasi morfologi menggunakan preparat Whole Mount dengan metode cepat dan klasik. Identifikasi molekular menggunakan metode PCR-SSCP (Polymerase Chain Reaction - Single Strand Conformation Polymorphism) dengan elektroforesis gel poliakrilamid (PAGE) 6% dan pewarnaan perak. Spesies kutu pada merpati yang teridentifikasi menggunakan preparat whole mount adalah Columbicola columbae L. Jantan. Identifikasi C.columbae L. secara molekular menunjukkan pita yang jelas pada DNA target COI 700 bp. C. columbae merupakan ektoparasit yang umum dan banyak ditemukan di merpati. Genus Columbicola hanya ditemukan diantara bulu dan bagian atas sayap merpati sehingga identifikasi menjadi penting untuk menentukan spesies Columbicola. Kata Kunci: Kutu, Morfologi, Molekular

USO DO AMSTAR 2 NAS METANÁLISES DE UMA REVISÃO GUARDA-CHUVA SOBRE O MANEJO NÃO FARMACOLÓGICO DA OSTEOARTRITE DOS JOELHOS: UM ESTUDO SECCIONAL
Authors: Chenu Anne Claire , Andrade Carlos Augusto Ferreira de 
Published: February 2023

A osteoartrite de joelhos é uma doença que afeta consideravelmente a qualidade de vida. O tratamento com o uso de fármacos ou medidas invasivas causa prejuízos aos doentes, evidenciando a importância do tratamento não farmacológico e não cirúrgico. Neste cenário, a busca por melhores condutas impulsiona o crescente o número de revisões sistemáticas sobre o tema. Contudo, também é observada uma baixa qualidade destas. Sendo assim, esse trabalho busca através do instrumento AMSTAR 2 identificar os possíveis preditores de qualidade bem como descrever o desempenho das metanálises usadas na revisão guarda-chuva “Efeito dos exercícios físicos na dor e na capacidade funcional de pacientes com osteoartrite dos joelhos: uma revisão guarda-chuva”. Este estudo cross seccional foi realizado usando o instrumento AMSTAR 2 e o software MATLAB. Os estudos foram classificados em alta, moderada, baixa ou criticamente baixa qualidade de acordo com o cumprimento dos domínios críticos e não críticos do instrumento e em sequência foi construído um score de porcentagem da contemplação dos itens do mesmo. Os resultados foram decepcionantes: das 23 revisões analisadas 22 apresentaram-se como criticamente baixa e uma como baixa. Dentre os fatores preditivos constaram como relevantes as Cocrhane reviews, o acesso livre e o financiamento externo. Diante disso é notória a necessidade dos autores de dominarem com maior destreza os pontos-chaves para a elaboração de um resultado com um menor risco de viés e os domínios críticos do instrumento. Posto isso, as conclusões encontradas na revisão guarda-chuva não apresentam relevância significativa, carecendo de novos estudos na área.

Abstract. Pollutant transport has a substantial impact on the
atmospheric environment in megacity clusters. However, owing to the lack of
knowledge of vertical pollutant structure, quantification of transport
processes and understanding of their impacts on the environment remain
inadequate. In this study, we retrieved the vertical profiles of aerosols,
nitrogen dioxide (NO2), and formaldehyde (HCHO) using multi-axis
differential optical absorption spectroscopy (MAX-DOAS) and analyzed three
typical transport phenomena over the North China Plain (NCP) and Yangtze
River Delta (YRD). We found the following: (1) the main transport layers
(MTL) of aerosols, NO2, and HCHO along the southwest–northeast
transport pathway in the Jing-Jin-Ji region were approximately 400–800,
0–400, and 400–1200 m, respectively. The maximum transport flux of HCHO
appeared in Wangdu (WD), and aerosol and NO2 transport fluxes were
assumed to be high in Shijiazhuang (SJZ), both urban areas being significant sources feeding regional pollutant transport pathways. (2) The NCP was affected by severe dust transport on 15 March 2021. The airborne dust suppressed dissipation and boosted pollutant accumulation, decreasing the height of high-altitude pollutant peaks. Furthermore, the dust enhanced
aerosol production and accumulation, weakening light intensity. For the
NO2 levels, dust and aerosols had different effects. At the SJZ and
Dongying (DY) stations, the decreased light intensity prevented NO2
photolysis and favored NO2 concentration increase. In contrast, dust
and aerosols provided surfaces for heterogeneous reactions, resulting in
reduced NO2 levels at the Nancheng (NC) and Xianghe (XH) stations. The
reduced solar radiation favored local HCHO accumulation in SJZ owing to the
dominant contribution of the primary HCHO. (3) Back-and-forth transboundary
transport between the NCP and YRD was found. The YRD-to-NCP and NCP-to-YRD
transport processes mainly occurred in the 500–1500 and 0–1000 m layers,
respectively. This transport, accompanied by the dome effect of aerosols,
produced a large-scale increase in PM2.5, further validating the
haze-amplifying mechanism.

Abstract. We reconstructed surface mass balance (SMB) around Dome Fuji, Antarctica,
over the last 5000 years using the data from 15 shallow ice cores and seven snow pits. The depth–age relationships for the ice cores were determined by synchronizing them with a layer-counted ice core from West Antarctica (WAIS Divide ice core) using volcanic signals. The reconstructed SMB records for the last 4000 years show spatial patterns that may be affected by their locations relative to the ice divides around Dome Fuji, proximity to the ocean, and wind direction. The SMB records from the individual ice cores and snow pits were stacked to reconstruct the SMB history in the Dome Fuji area. The stacked record exhibits a long-term decreasing trend at -0.037±0.005 kg m−2 per century over the last 5000 years in the preindustrial period. The decreasing trend may be the result of long-term surface cooling over East Antarctica and the Southern Ocean and sea ice expansion in the water vapor source areas. The multidecadal to centennial variations of the Dome Fuji SMB after detrending the record shows four distinct periods during the last millennium: a mostly negative period before 1300 CE, a slightly positive period from 1300 to 1450 CE, a slightly negative period from 1450 to 1850 CE with a weak maximum around 1600 CE, and a strong increase after 1850 CE. These variations are consistent with those of previously reconstructed SMB records in the East Antarctic plateau. The low accumulation rate periods tend to coincide with the combination of strong volcanic forcings and solar minima for the last 1000 years, but the correspondence is not clear for the older periods, possibly because of the lack of coincidence of volcanic and solar forcings or the deterioration of the SMB record due to a smaller number of stacked cores.
Potential tsunami hazard of the southern Vanuatu subduction zone: tectonics, case study of the Matthew Island tsunami of 10 February 2021 and implication in regional hazard assessment

Abstract. The Vanuatu subduction zone (VSZ) is known to be seismically very active,
due to the high convergence rate between the Australian and Pacific tectonic plates for the majority of the margin. However, this is not the case on its southernmost part south of latitude 22.5∘ S and east of longitude 170∘ E, which is neither highly tectonically active nor has it produced large tsunamis over the past 150 years. It has also not been widely studied. On the 11 February 2021 (10 February UTC), a magnitude
Mw 7.7 earthquake triggered a tsunami warning in New Caledonia and Vanuatu 20 min after midnight (local time). With an epicentre
located close to the volcanic islands of Matthew and Hunter, this shallow
reverse-faulting rupture (< 30 km depth) was able to deform the
seabed and produce a tsunami. This was confirmed 45 min later by the coastal gauges of the Loyalty and the south Vanuatu islands, which recorded the first tsunami waves. Showing a typical recorded amplitude of less than 1 m, with a maximum of ∼ 1.5 m in Lenakel (Tanna, Vanuatu), it was
observed on most coastal gauges and DART stations in the south-west Pacific
region as far as Tasmania to the south and Tuvalu to the north at distances
of ∼ 3000 and ∼ 1800 km from the epicentre. In
this study, the tsunamigenic potential of the southernmost part of the VSZ
and the implications in terms of regional hazard assessment are discussed
through (1) the presentation of the complex tectonic settings of this
“transition zone” between the Solomon–Vanuatu and the Tonga–Kermadec
trenches, (2) the case study of the 10 February 2021 tsunami at a south-west
Pacific regional scale using three different tsunami generation scenarios
computed with the COMCOT modelling code on a set of 48 nested bathymetric
grids, and (3) the simulation of a plausible Mw 8.2 scenario
encompassing the active part of this “transition zone”. The validation of
the Mw 7.7 parameters for tsunami modelling provides the means to further assess the hazard from potential tsunamis triggered by higher
magnitude earthquakes in this region. Tsunami records highlight that
> 28 cm wave amplitudes were recorded at eight different coastal
gauges, including one with an amplitude of more than 1 m (Lenakel, Tanna,
Vanuatu). The tsunami threat at that location would be large enough to
warrant an onshore evacuation. Finally, it helps to highlight the
significant role played by the numerous submarine features in the region,
the Norfolk Ridge being the most important, which acts like a waveguide from the north to the south.
Comparing Emergency Department Stress of Lateral Compression Type 1 Pelvis Fractures With a Validated Instability Scoring System

Published: February 2023

Introduction:
Lateral compression type 1 (LC1) pelvic ring injuries represent a heterogeneous group of fractures with controversial surgical indications. Recently, multiple institutions have suggested the safety and reliability of an emergency department (ED) stress to evaluate for occult instability. The purpose of this study was to correlate ED stress examination of LC1 pelvis fractures against a validated fracture instability scoring system.

Methods:
This was a retrospective review of a consecutive series of 70 patients presenting with minimally displaced LC1 fractures at a level 1 academic trauma center. All patients were stressed in the ED radiology suite, and displacement was measured by comparing calibrated stress radiographs with static radiographs (>10 mm displacement defined positivity). ED stress results were compared with radiographic scores assigned according to the validated Beckmann scoring system (score <7: stable—nonsurgical recommendation; score 7 to 9: indeterminant recommendation; and score >9: unstable—surgical recommendation).

Results:
Thirteen patients had a positive ED stress examination, and 57 patients stressed negative. The mean displacement was significantly different between the three groups (Beckmann 5 to 6: 3.31 mm, SD = 2.4; Beckmann 7 to 9: 4.23 mm, SD = 3.2; Beckmann 10+: 12.1 mm, SD = 8.6; P < 0.001). Zero of 18 patients in the stable group stressed positive, and only 3 of 38 patients in the indeterminant group stressed positive (7.9%). Finally, 10 of 14 patients in the unstable group stressed positive (71.4%; P < 0.001). Sacral displacement (P = 0.001), superior ramus location (P < 0.02), and sacral columns (P < 0.001) significantly predicted ED stress positivity in multivariate analysis.

Conclusions:
Comparison of a validated instability scoring system with ED stress examination of minimally displaced LC1 fractures in awake and hemodynamically stable patients showed excellent correlation. This suggests that the ED stress examination is a useful diagnostic adjunct. LC1 fracture characteristics should be analyzed to determine which pelvic fracture characteristics determine occult instability before stress examination.

Level of Evidence:
Level III diagnostic.
