Published: August 2023

Abstract. Photooxidants drive many atmospheric chemical processes. The photoexcitation of light-absorbing organic compounds (i.e., brown carbon,
BrC) in atmospheric waters can lead to the generation of reactive organic triplet excited states (3C∗), which can undergo further reactions to produce other photooxidants such as singlet oxygen (1O2∗). To determine the importance of these aqueous photooxidants in secondary organic aerosol (SOA) formation and transformation, we must know their steady-state concentrations and quantum yields. However, there have been limited measurements of aqueous 3C∗ and 1O2∗ in atmospheric samples outside of North America and Europe. In this work, we report the first measurements of the steady-state concentrations and quantum yields of 3C∗ and 1O2∗ produced in aerosols in South China. We quantified the production of 3C∗ and 1O2∗ in illuminated aqueous extracts of PM2.5 collected in different seasons at two urban sites and one coastal semi-rural site during a year-round study conducted in Hong Kong SAR, South China. The mass absorption coefficients at 300 nm for BrC in the aqueous PM2.5 extracts ranged from 0.49 to 2.01 m2 g-C−1 for the three sites. Both 1O2∗ and 3C∗ were produced year-round. The steady-state concentrations of 1O2∗ ([1O2∗]ss) in the illuminated aqueous extracts ranged from 1.56×10-14 to 1.35×10-12 M, with a study average of (4.02±3.52)×10-13 M. At nearly 2 orders of magnitude lower than [1O2∗]ss, the steady-state concentrations of 3C∗ ([3C∗]ss) ranged from 2.93×10-16 to 8.08×10-14 M, with a study average of (1.09±1.39)×10-14 M. The quantum yields of 1O2∗ and 3C∗ also spanned wide ranges across samples, with a range of 1.19 % to 13.74 % and an average of (5.19±2.63) % for 1O2∗ and a range of 0.05 % to 3.24 % and an average of (0.56±0.66) % for 3C∗. The [1O2∗]ss and [3C∗]ss correlated with the concentration and absorbance of BrC, thus implying that the amount of BrC drives the steady-state concentrations of these photooxidants. The locations (urban vs. semi-rural) did not have a significant effect on [3C∗]ss and [1O2∗]ss, which indicated that BrC from local sources did not have a significant influence on the year-round 3C∗ and 1O2∗ production. 3C∗ and 1O2∗ production were found to be the highest in winter and the lowest in summer for all three sites. The observed seasonal trends of 1O2∗ and 3C∗ production could be attributed to the seasonal variations in the long-range air mass transport. Our analysis highlighted the key role that regional sources play in influencing the composition and concentrations of water-soluble BrC in winter PM2.5 in Hong Kong SAR, which contributed to their highest 3C∗ and 1O2∗ production. The current results will be useful for modeling seasonal aqueous organic aerosol photochemistry in the South China region.

Abstract. Global storm-resolving models (GSRM) use strongly refined horizontal grids in comparison to climate models typically used in the Coupled Model Intercomparison Project (CMIP) but comparable vertical grid spacings. Here, we study how changes in vertical grid spacing and adjustments of the integration time step affect basic climate quantities simulated by the ICON-Sapphire atmospheric GSRM. Simulations are performed over a 45-day period for five different vertical grids having between 55 and 540 vertical layers and maximum tropospheric vertical grid spacings between 800 and 50 m. The effects of changes in vertical grid spacing are compared to differences between simulations with horizontal grid spacings of 5 and 2.5 km. For most quantities considered, halving vertical grid spacing has smaller effects than halving horizontal grid spacing but is not negligible. Every halving of the vertical grid spacing jointly with the necessary reductions of the time step length increases cloud liquid water by about 7 %, compared to about 16 % decrease for halving the horizontal grid spacing. The effect is due to both vertical grid refinement and time step reduction. There is no tendency of convergence in the range of grid spacings tested here. The cloud ice amount also increases with a refinement of the vertical grid but is hardly affected by the time step length and does show a tendency of convergence. While the effect on shortwave radiation is globally dominated by the changed reflection due to the changed cloud liquid water content, effects on longwave radiation are more difficult to interpret because changes in cloud ice concentration and cloud fraction are anticorrelated in some regions.

Abstract. In order to complement the picture of the atmospheric water cycle in the Southern Ocean, we have continuously monitored water vapor isotopes since January 2020 in Amsterdam Island (37.7983 °S, 77.5378 °E) in the Indian Ocean. We present here the first 2-year-long water vapor isotopic record monitored on this site. We show that the vapor isotopic composition largely follows the vapor mixing ratio, as expected in marine boundary layers. However, we evidence 11 cold front periods of a few days where there is a strong loss of correlation between water vapor δ18O and mixing ratio. These periods are associated with abrupt negative excursions of water vapor δ18Ο, often occurring toward the end of precipitation events. Six of these events show a decrease in gaseous elemental mercury suggesting subsidence of air from higher altitude. Accurately representing the water isotopic signal during these cold fronts is a real challenge for the atmospheric components of Earth System models equipped with water isotopes. While the ECHAM6-wiso model was able to reproduce most of the sharp negative water vapor δ18O excursions, the LMDZ-iso model at 2° (3°) resolution was only able to reproduce 7 (1) of the negative excursions. Based on a detail model-data comparison, we conclude that the most plausible explanations for such isotopic excursions are rain-vapor interactions associated with subsidence at the rear of a precipitation event.
Eddy-induced chlorophyll profile characteristics and underlying dynamic mechanisms in the South Pacific Ocean

Published: August 2023

Abstract. Many studies have consistently demonstrated that the near-surface phytoplankton chlorophyll (Chl) levels in anticyclonic eddies (AEs) are higher than in cyclonic eddies (CEs) in the South Pacific Ocean (SPO) using remote sensing data, which is attributed to higher phytoplankton biomass or physiological adjustments in AEs. However, the characteristics of the Chl profile induced by mesoscale eddies and their underlying dynamic mechanism have not been comprehensively studied by means of field measurement. In this study, we mainly utilized BGC-Argo data to investigate the relationships between Chl levels and environmental factors (CPhyto, Nitrate, Temperature and Light) and the underlying dynamic mechanisms of mesoscale eddies in SPO. Our findings showed that, the elevated Chl levels in AEs primarily result from increased phytoplankton biomass within the Mixed Layer Depth (MLD), which is induced by enhanced nutrient availability due to the deepening MLD in AEs. At depths ranging from 50 m to 110 m (the depth between the bottom of the mixed layer and pycnocline), the dominant factor affecting higher Chl levels in CEs is the physiological adaptation of phytoplankton, driven by reduced temperature and light availability. Between 110 m and 150 m (near the depth of pycnocline or bottom of the euphotic zone), both phytoplankton biomass induced by eddy pumping and physiological adjustments for lower light and temperature contributed to higher Chl levels in CEs. At depths exceeding 150 m (beyond the euphotic zone), higher Chl in AEs is primarily influenced by phytoplankton biomass as a result of the downwelling by eddy pumping. To a certain extent, this work would advance our comprehensive understanding of the physical-biological interactions of mesoscale eddies and their impacts on primary productivity throughout the water column, which has important implications for accurately assessing the biogeochemical processes and ocean carbon cycle.
A change in perspective: downhole cosmic-ray neutron sensing for the estimation of soil moisture
Authors: Rasche Daniel , Weimar Jannis , Schrön Martin , Köhli Markus , Morgner Markus , Güntner Andreas , Blume Theresa
Published: August 2023

Abstract. Above-ground cosmic-ray neutron sensing (CRNS) allows for the non-invasive estimation of the field-scale soil moisture content in the upper
decimetres of the soil. However, large parts of the deeper vadose zone remain outside of its observational window. Retrieving soil moisture
information from these deeper layers requires extrapolation, modelling or other methods, all of which come with methodological challenges. Against
this background, we investigate CRNS for downhole soil moisture measurements in deeper layers of the vadose zone. To render calibration with in situ
soil moisture measurements unnecessary, we rescaled neutron intensities observed below the terrain surface with intensities measured above a waterbody. An experimental set-up with a CRNS sensor deployed at different depths of up to 10 m below the surface in a groundwater observation well
combined with particle transport simulations revealed the response of downhole thermal neutron intensities to changes in the soil moisture content at
the depth of the downhole neutron detector as well as in the layers above it. The simulation results suggest that the sensitive measurement radius
of several decimetres, which depends on soil moisture and soil bulk density, exceeds that of a standard active neutron probe (which is only about
30 cm). We derived transfer functions to estimate downhole neutron signals from soil moisture information, and we describe approaches for
using these transfer functions in an inverse way to derive soil moisture from the observed neutron signals. The in situ neutron and soil moisture
observations confirm the applicability of these functions and prove the concept of passive downhole soil moisture estimation, even at larger depths,
using cosmic-ray neutron sensing.
Nouméa: a new multi-mission calibration and validation site for past and future altimetry missions?
Authors: Chupin Clémence , Ballu Valérie , Testut Laurent , Tranchant Yann-Treden , Aucan Jérôme
Published: August 2023

Abstract. Today, monitoring the evolution of sea level in coastal
areas is of importance, since almost 11 % of the world's population
lives
in low-lying areas. Reducing uncertainties in sea level estimates requires
a
better understanding of both altimetry measurements and local sea level
dynamics. In New Caledonia, the Nouméa lagoon is an example of this
challenge, as altimetry, coastal tide gauge, and vertical land motions
from global navigation satellite systems (GNSSs) do not provide consistent
information. The GEOCEAN-NC 2019 field campaign addresses this issue with
deployments of in situ instruments in the lagoon (GNSS buoy,
pressure gauge, etc.),
with a particular focus on the crossover of one Jason-series track and two
Sentinel-3A missions tracks. In this study, we propose a method to
virtually
transfer the Nouméa tide gauge at the altimetry crossover point, using
in situ data
from the field campaign. Following the philosophy of calibration and validation (Cal/Val) studies, we
derive absolute altimeter bias time series over the entire Jason and
Sentinel-3A periods. Overall, our estimated altimeter mean biases are
slightly larger by 1–2 cm compared to Corsica and Bass Strait results,
with
inter-mission biases in line with those of Bass Strait site. Uncertainties
still remain regarding the determination of our vertical datum, only
constrained by the three days of the GNSS buoy deployment. With our method,
we are able to re-analyse about 20 years of altimetry observations and
derive a linear trend of −0.2 ± 0.1 mm yr−1 over the bias time series.
Compared to previous studies, we do not find any significant uplift in the
area, which is more consistent with the observations of inland permanent
GNSS stations. These results support the idea of developing Cal/Val
activities in the lagoon, which is already the subject of several
experiments for the scientific calibration phase of the SWOT wide-swath
altimetry mission.
Trade Wars and Disrupted Global Commodity Chains
Authors: Ciccantell Paul S. , Smith David , Sowers Elizabeth
Published: August 2023

The literatures on global commodity chains and global value chains rest on an unquestioned assumption: the continual expansion of globalization. The Trump Administration's trade wars challenged this foundational assumption and even today the new Biden regime also hints at the shift away from global supply chains. We find that the prior administration’s efforts caused continued disruption of long-established commodity chains in steel, aluminum, automobiles, and other manufactured products. Flows of raw materials, intermediate products and components, and finished goods now confront higher costs. Firms continue efforts to restructure commodity chains in ways that will require the disarticulation of some nodes and the creation of new nodes. We claim that these trade wars and breakdown of global commodity chains (GCCs) may in fact mark the start of the breakdown of the U.S.-led world order. This shift harkens the onset of a new era of economic and geopolitical conflict. A key question: has this disruption of old patterns and rise of new ones continued in the post-Trump era? Does the familiar pattern of globalization continue – or is competition, contestation and disarticulation leading to sectoral economic changes that drive larger patterns of economic ascent, dominance, and decline in the world economy?

Published: August 2023

Footstrike pattern has received increased attention within the running community because there is a common belief that forefoot strike running (FFS) is more advantageous (i.e., improve performance and reduce running injuries) than rearfoot strike running (RFS) in distance running. Literature reports suggest greater knee joint flexion magnitude and initial knee angle during stance in FFS compared with RFS running We examined the EMG activation of the triceps surae muscles during an acute transition from RFS to FFS strike. We tested the hypothesis that due to larger knee flexion in FFS the gastrocnemius muscles possibly decrease their EMG activity because muscle fascicles operate under unfavorable conditions. Fourteen competitive healthy middle- and long-distance runners who were habitual RFS runners ran on a treadmill at three speeds: 12, 14, and 16 km·h-1. Each running speed was performed with both FFS and RFS patterns. Lower limb kinematics in the sagittal plane and normalized electromyography (EMG) activity of medial gastrocnemius proximal, middle and distal regions, lateral gastrocnemius and soleus muscles were compared between footstrike patterns and running speeds across the stride cycle. Contrary to our expectations, the knee joint range of motion was similar in FFS and RFS running. However, the sagittal plane ankle joint motion was greater (p < 0.01) while running with FFS, resulting in a significantly greater muscle-tendon unit lengthening (p < 0.01) in FFS compared with RFS running. In addition, medial and lateral gastrocnemius showed higher EMG activity in FFS compared with RFS running in the late swing and early stance but only for a small percentage of the stride cycle. However, strike patterns and running speed failed to induce region-specific activation differences within the medial gastrocnemius muscle. Overall, well-trained RFS runners are able to change to FFS running by altering only the ankle joint kinematics without remarkably changing the EMG activity pattern.

PEMBERDAYAAN MEDITOR LOKAL SEBAGAI PROBLEM SOLVER DALAM SENGKETA PERCERAIAN MASYARAKAT MUSLIM DESA KALISAT PASURUAN
Authors: Salam Nor , Nurcholis Moch. , Junaidin Junaidin
Published: August 2023

The activity with the theme “Empowering Local Meditors as Problem Solvers in Divorce Disputes in the Muslim Community of Kalisat Pasuruan Village” was motivated by the presence of a Supreme Court Regulation (PERMA) with one of its “doctrines” namely the validity of mediators who are entitled to mediate in divorce disputes are mediators consisting of judges or non-judge but certified mediators. This has implications for the "oppression" of local mediators with a wealth of functional insight into the life of village communities. For this reason, in this mentoring program, we use Asset Based Community Development (ABCD) as the approach used. This departs from the initial assumption that local mediators have the ability and insight that are functional in people's lives, primarily related to divorce dispute resolution. Through this mentoring program, there is an increase in the understanding of mediators in understanding and practicing mediation which is known outside the provisions of fiqh, as a companion to the abilities they already have.
The Determinants of Tax Revenue in the Context of International Transactions in the Latin America and Caribbean (LAC) Regions 2002-2019
Authors: Nugraha Hendiva Tri , Wijaya Suparna
Published: August 2023

Tax revenue is one of the backbones of  economy in almost every country in the world. There are several determinants that influence the amount of tax revenue in one country, one of which is international transaction activities. Such activities can partly be presented by three variables; Foreign Direct Investment (FDI), Trade Openness (TO), and External Debt. This study aims to acknowledge the effects of international transaction experienced by a country  regarding its tax revenue.  External Debt is used as a moderating variable to the effects of FDI  and TO on tax revenue. The data source was taken from the World Bank within the period of 2002-2019 in 19 countries around LAC regions. The study implements an associative quantitative method with PCSE regression. The result showed that FDI affects tax revenue negatively, whereas trade openness and external debt affect tax revenue positively. External debt as a moderating variable strengthens the effect of FDI and weakens the effects of trade openness to tax revenue. Further research is expected to include all the LAC countries, add more variables  relevant to the international transactions, and renew the research period.

Parteiras e médicos
Authors: De Alencar Ribeiro Janaína
Published: August 2023

Parteiras e médicos são guiados por paradigmas existenciais contrapostos, que em seu limite, poderiam ser complementares: as primeiras guiando-se pelo conhecimento integral da mulher e os últimos, pelo limite da medicina científica e tecnológica. Portanto as parteiras (não-médicos) podem garantir o espaço do parto humanizado e naturalizado, cabendo a intervenção médica somente quando houver necessidade de cirurgia. Porém, o que temos é a marginalização da prática das parteiras e uma hipermedicalização do parto feito por médicos.

impacto do paciente oncológico ativista no ecossistema de saúde
Authors: Rossi de Oliveira Ludmilla
Published: August 2023

Por meio de iniciativas independentes, pacientes manifestam-se de acordo com três diferentes grupos comportamentais: cativos, fleumáticos e ativistas. O presente ensaio discute a importância dos pacientes ativistas no ecossistema da saúde pública e privada do Brasil. Os pacientes oncológicos ativistas e seus projetos geram impacto em outros pacientes, em toda a cadeia dos profissionais de saúde e na consciência da população. A participação dos pacientes ativistas em iniciativas, como microcanais de conteúdo em redes sociais, campanhas e participação em Organizações Não Governamentais, também é essencial para a conscientização, desde que ofereçam representatividade e responsabilidade. Oativismo dos pacientes não está ligado a um perfil específico, mas sim a um grande desejo de conexão com outras pessoas, queestejam vivendo experiências ou dificuldades similares. O ativismo pode ser encarado como uma atividade recorrente, voluntária e odesejo de construir mudanças de comportamento. As biografias e projetos dos pacientes ativistas são transformados em legado,quebrando o estereótipo de uma pessoa doente para uma pessoa que protagoniza seu tratamento, disseminando sua experiência. Tornam-se necessários novos diálogos sobre a relação dos profissionais de saúde com seus pacientes e da responsabilidade dos pacientes ativistas com suas audiências.

No início da pandemia causada pelo SARS-CoV-2, um dos temas mais debatidos nas redes sociais brasileiras foi a adoção das medidas preventivas restritivas: o isolamento social, distanciamento social e a quarentena. O presente estudo teve como com objetivo identificar a percepção da população sobre as medidas de prevenção e controle da COVID-19, no Brasil, visando contribuir para o aprimoramento dos planos de comunicação do Sistema Único de Saúde, sobre o controle da doença. O Twitter Archiver foi utilizado para coletar tweets com os termos de busca “covid OR corona AND quarentena OR isolamento OR distanciamento”, nos dias 07 e 09 de maio de 2020. Foi realizada a análise de conteúdo temática, com categorias definidas a priori e a posteriori. Esse estudo preliminar identificou que a maior parte dos tweets analisados não apresentava um posicionamento ou era favorável às medidas sanitárias. A maioria dos tweets com posicionamento favorável às medidas utilizava, como referencial, informações divulgadas pelos órgãos de saúde. Adicionalmente, os resultados apontam que a avaliação desses usuários, em relação à eficácia e efetividade das medidas preventivas, pode também estar sendo influenciada por referenciais político-partidários.

Este artigo apresenta a pesquisa qualitativa que objetivou saber como se dá o cuidado em saúde sexual das mulheres que sãoprostitutas: se há diferença no tratamento que recebem em consultas ginecológicas, se recebem mais orientações quanto aosmétodos preventivos de IST em comparação a outras mulheres não prostitutas. A pesquisa realizou entrevistas face a face comuso de roteiro semiestruturado aplicados com 11 mulheres prostitutas, com idades entre 19 a 59 anos, da região de baixo meretríciono centro da cidade de Santos/SP. O cuidado para essas mulheres, em geral, diz respeito ao uso do preservativo masculinocom seus clientes, à realização de exames de IST/HIV e ginecológicos, à higiene corporal, ao falar de seu trabalho aos profissionaisde saúde e às suas orientações sexuais. Observou-se que as mulheres abordadas não receberam orientações específicas referentesàs medidas preventivas em saúde por atuarem na prostituição.

No contexto da Política Municipal de Atenção à Saúde Integral da População LGBTT do município de São Paulo e da disponibilizaçãoda hormonioterapia para população transexual, objetiva-se relatar a vivência de um grupo de orientação sobre hormonioterapiadestinado a travestis e transexuais acolhidas em equipamentos sociais deste município. As atividades de roda de conversa foramrealizadas em um Centro de Acolhida, com o apoio de equipes de Consultório na Rua, além de uma médica e um psicólogo como facilitadores da atividade. Foram recorrentes nos relatos a vivência e naturalização da violência; as dificuldades de acesso aos serviços devido ao preconceito; e a automedicação com hormônios feminilizantes, pelo desejo intenso de mudanças no corpo. Os relatos apontaram, também, grande complexidade nas subjetividades das pessoas identificadas como trans. É necessário que o tema seja incluído de forma transversal em todos os processos de formação dos profissionais, pois a não observância do respeito à individualidade da sexualidade tem se constituído em importante barreira à adesão e ao estabelecimento de vínculos aos serviços de saúde.
On one series of the VI century AD iron one-piece asian helmets
Authors: Kubik Adam L. , Radyuš Oleg A. , Vyazov Leonid A.
Published: August 2023

The article describes a series of helmets of a type that probably spread across Asia and Eastern Europe in the middle to the second half of the VI century AD. These helmets are characterised by a very particular construction: they have a bowl hammered from a single piece of iron, with an additional band in the lower part, connected to the inside or outside edge of the helmet. Additionally, a chainmail collar was attached to the lower part of the helmet. The attached chainmail provides additional protection around the entire circumference including the forehead above the eyes. This characteristic would remain unpopular in European armaments for quite a long period and was only popularised in central and eastern Europe around the XVI century AD [1: 130]. This article analyses a possible Iranian provenance of the helmets of this type as well as hypothesizes about the possible reason for the spread of these helmets on the territory of Eastern Europe and Asia.

Granular Matter in Space
Authors: Sperl Matthias
Published: August 2023

The investigation of granular matter benefits from experiments in microgravity in several ways and may be categorized into three regimes of increasing density:

(1) Granular gases [1] are dilute systems and subject to sedimentation which can be avoided in microgravity. Their agitation by magnetic excitation allows for the study of cooling, velocity distributions and the onset of particle agglomeration.

(2) Granular fluids [2] are denser than granular gases and are monitored by scattering techniques. On Earth, granular fluids are anisotropic and inhomogeneous. In microgravity, agitated homogeneous granular fluids can be prepared for densities up to the jamming transition.

(3) Granular packings [3] close to the jamming transisionexperience a large pressure gradient on Earth which is absent in microgravity. Hence, sound transmission can be studied at very low confinement. Similarly, microgravityoffers unique opportunities for the rheology on dense granular systems.
Frustrated Bearings
Authors: Herrmann Hans Jürgen
Published: August 2023

A bearing is a system of spheres (or disks) in contact. If in a bearing every loop is even, one can obtain “bearing states”, in which touching spheres roll on each other without slip. We frustrate a system of touching spheres by imposing two diﬀerent bearing states on opposite sides and search for the conﬁgurations of lowest energy dissipation. For Coulomb friction (with random friction coeﬃcients) in two dimensions, a sharp line separates the two bearing states and we prove that this line corresponds to the minimum cut. Astonishingly however, in three dimensions, intermediate bearing domains, that are not synchronized with either side, are energetically more favourable than the minimum-cut surface. This novel state of minimum dissipation is characterized by a spanning network of slip-less contacts that reaches every sphere. Such a situation becomes possible because in three dimensions bearings of loops of size four have four degrees of freedom. By considering spheres of different size, packings with bearing states can even be made space-filling. The construction and mechanical properties of such space-filling bearings will be discussed. Space-filling bearing states can be viewed as a realization of solid turbulence exhibiting Kolmogorov scaling and anomalous heat conduction. Bearings states can be perceived as physical realizations of networks of oscillators with asymmetrically weighted couplings. These networks can exhibit optimal synchronization properties through tuning of the local interaction strength as a function of node degree or the inertia of their constituting rotor disks through a power-law mass-radius relation. As a consequence, one finds that space filling bearings synchronize fastest, when they are hollow.

Gen PARK2 mã hóa protein Parkin, biểu hiện hoạt động của một enzym ligase E3 ubiquitin. Đột biến trên gen PARK2 là một trong những nguyên nhân chính gây ra thể Parkinson gia đình, di truyền lặn trên nhiễm sắc thể thường, đặc trưng bởi sự khởi phát sớm (trước 50 tuổi). Đột biến xóa đoạn gen PARK2 chiếm tỷ lệ khoảng 9,5% - 14% số bệnh nhân khởi phát sớm. Nghiên cứu này được thực hiện nhằm mục đích xác định đột biến xóa đoạn trên gen PARK2 ở bệnh nhân Parkinson và các thành viên gia đình. Nghiên cứu được thực hiện trên 30 bệnh nhân Parkinson với độ tuổi trung bình là 51,47 ± 11,91 tuổi, tỷ lệ nam/nữ bằng 1,3. Trong đó, chúng tôi phát hiện 4/30 bệnh nhân (tỷ lệ 13,3%) mang đột biến xóa đoạn gen PARK2 bằng kỹ thuật MLPA. Nghiên cứu có ý nghĩa thực tiễn đối với cả bệnh nhân và gia đình, đóng góp vào cơ sở dữ liệu bệnh Parkinson đồng thời là cơ sở để tư vấn di truyền cho các thành viên trong gia đình.

Gãy xương đòn là một trong các chấn thương thường gặp và thường được chỉ định điều trị bảo tồn bằng đai số 8. Gần đây, phẫu thuật kết hợp xương đòn ngày càng được mở rộng và cho thấy nhiều ưu điểm như tỷ lệ chậm liền, khớp giả thấp, phục hồi chức năng chi trên sớm. Mục tiêu nghiên cứu là đánh giá kết quả trung hạn phẫu thuật kết hợp xương đòn bằng nẹp khóa titan phía trên tại Bệnh viện Bưu Điện từ tháng 01/2019 đến 11/2021. Chúng tôi thực hiện nghiên cứu mô tả trên 50 bệnh nhân được phẫu thuật kết hợp xương đòn bằng nẹp khóa titan phía trên trong thời gian từ tháng 01/2019 đến 11/2021, đánh giá mức độ thương tổn chi trên bằng thang điểm quick DASH. Tuổi trung bình 39,24 ± 12,97; nam/nữ = 4/1; 80% bệnh nhân gãy 1/3 giữa, 20% bệnh nhân gãy 1/3 ngoài, 10% bệnh nhân có tổn thương dây chằng quạ đòn; thời gian theo dõi trung bình 32,28 ± 10,37 tháng; 100% bệnh nhân liền xương trong vòng 6 tháng; không có bệnh nhân nào nhiễm trùng, lộ nẹp vis ra da; điểm quick DASH trung bình 0,591; tỷ lệ sẹo xấu 68% và sẹo lồi 18%; tổn thương thần kinh thượng đòn 32% và nhìn thấy nẹp dưới da 32%. Mặc dù là phẫu thuật an toàn với tỷ lệ liền xương 100%, không có biến chứng nặng, tỷ lệ tháo bỏ thấp, hồi phục chức năng khớp vai gần như hoàn toàn nhưng vẫn còn một số hạn chế trong theo dõi trung hạn là sẹo mổ xấu và tổn thương thần kinh thượng đòn.

Chậm tăng trưởng là biến chứng thường gặp ở trẻ bệnh thận mạn (CKD) và bệnh thận mạn giai đoạn cuối (ESRD). Trẻ ESRD chậm tăng trưởng do nhiều yếu tố như dinh dưỡng kém, thiếu máu, rối loạn chuyển hóa muối khoáng và xương, hóc môn tăng trưởng, sử dụng corticoid. Nghiên cứu mô tả trên 54 trẻ ESRD điều trị thay thế thận (79,6% thẩm phân phúc mạc và 20,4% thận nhân tạo chu kỳ) tại viện Nhi Trung Ương (55,6% nam). Tuổi nhỏ nhất là 5 tháng và lớn nhất 16 tuổi. 81,5% trẻ chậm tăng trưởng theo WHO với chiều cao theo tuổi (HFA) dưới -2SD. 23 trong 54 trẻ (42,6%) chiều cao thấp mức độ nặng với HFA dưới -3SD. Tỷ lệ trẻ giảm canxi máu toàn phần và thiếu vitamin D là 68,5% và 48,1%. 80,9% trẻ tăng phospho máu và 96,7% trẻ tăng PTH. Tuy nhiên, không có sự khác biệt về tỷ lệ giảm canxi máu toàn phần, tăng phospho máu giữa nhóm trẻ chiều cao thấp và chiều cao bình thường theo tuổi. PTH máu tăng có liên quan với tỷ lệ trẻ ESRD chiều cao thấp (p < 0,05).
