Authors: Kühne Thilo , Antonescu Bogdan , Groenemeijer Pieter , Púčik Tomáš
Published: March 2023

Until now, studies on lightning fatalities have been available from a few individual countries but not for Europe as a whole. We here report on lightning strike fatalities in the period from 2001 to 2020 that happened across Europe, all of Turkey, the Caucasus countries (Armenia, Azerbaijan, and Georgia), based on reports from the European Severe Storms Database (ESWD). The ESWD records are based on publicly available data derived from local authorities, police and fire departments, newspapers, and news agencies, which are collected by ESSL and its partners.

In total, 1280 individual fatalities were recorded in the ESWD during this period. We report on the spatial distribution of fatalities, and the distribution of fatalities per age group and sex, whether the victims were at work or undertaking leisurely activities, and in which kind of landscape they were hit. Furthermore, we considered the circumstances that led to lightning fatalities that occur indoors.

We found that an average of 64 people are killed by lightning strikes every year, and that the majority (78%) are male. The countries with the highest rate of lightning fatalities per capita are Bulgaria (8.6 per million per year), Moldova (7.7), and Romania (5.8). The lowest rates are found in Belgium (0.1), Malta (0.1), and Portugal (0.1). The proportion of fatalities in work activities increases from Western to Southeastern Europe. When working, people are most typically killed when working on the fields while during leisure, people are most typically killed when hiking. Of the rare indoor fatalities (1.6%), a majority (11 of 15 known cases, 72%) were killed by fire and smoke that broke out after the lightning struck. Referring to the age of fatalities, people at the age of 10-19 have the biggest share of all age decennium with a peak at the age of 15 (33 fatalities). Divided by sex, male fatalities also show the biggest share in the age decade of 10-19, while female fatalities peak in the age decade of 50-59.
Evaluation of ESTOFEX convective outlooks from 2007 to 2021. Part 1: forecasters and regional performance of lightning predictions
Authors: van der Velde Oscar ,   ESTOFEX Team
Published: March 2023

The European Storm Forecast Experiment (ESTOFEX) is a well known project of volunteer meteorologists making forecasts of thunderstorms and their severe weather threats for Europe for 20 years (since October 2002). Originally, the forecasts consisted of three severe weather risk lines as well as one thunderstorm line. The verification of the dichotomic lightning forecasting skill was presented at the 4th ECSS in Trieste, 2007.

In 2009 ESTOFEX switched to the use of two thunderstorm probability lines, tentatively marked “15% probability” and “50% probability” of thunderstorms within 40 km from each location. A verification of these lightning probability forecasts over a 4-year period was presented at the 7th ECSS in Helsinki in 2013 (doi: 10.13140/RG.2.1.1026.1845).

We update the verification of lightning probability areas to include 8 more years, covering 2009-2021 (incl.), and evaluate consistency of each forecaster by histograms and maps of thunderstorm occurrence (observed mean frequency for a location) for each category of forecast. Other aspects of this work will be presented in Part 2 (poster by Mateusz Taszarek). Gridded lightning data from ATDNET is used, as well as severe weather reports from the ESSL European Severe Weather Database. The ESTOFEX forecast category definitions are 0-15%, 15-50%, >50% forecasts for thunder, 0-5% (Level 1) and 5-15% (Level 2) for severe weather, and >15% (Level 3) for extremely severe weather, respectively.

As in the previous work, two key questions are answered:

(1) “Of all the times a location was included in a certain forecast category (e.g. 15-50% area), how often was the phenomenon observed?"

This returns a percentage for each location on the map. These locations can be plotted on the map or grouped into 3 overlapping histograms, one for each forecast category. The overlap and calibration can be judged for each forecaster and by geographic regions. The spatial criterion (e.g. phenomenon within 40 km from a point) can be varied.

(2) “If a spatial thunderstorm density was observed, which forecast probability area was it included in?"

For each category of observed spatial density around a point (or a Practically Perfect Hindcast, see Part 2), a map and histogram can be plotted of the corresponding mean forecast category frequency (or difference), to find areas where forecasters most frequently under- or overestimate activity, for example by season.
Toward The Development of Hailstorm Climatologies Derived From Reanalyses and Infared/Passive Microwave Satellite Imagers

Published: March 2023

Geostationary satellite imagers, such as those of the Geostationary Operational Environmental Satellite (GOES) and Meteosat series, provide both historical and near-real-time observations of cloud top patterns that are commonly associated with severe convection. Environmental conditions favorable for severe weather are thought to be represented well by reanalyses. Predicting exactly where convection and costly storm hazards like hail will occur using models or satellite imagery alone, however, is extremely challenging. The multivariate combination of satellite-observed cloud patterns with reanalysis environmental parameters, linked to United States Next Generation Weather Radar- (NEXRAD-) estimated Maximum Expected Size of Hail (MESH) using a deep neural network (DNN), enables estimation of potentially severe hail likelihood for any observed storm cell. These estimates are specifically designed to make hail likelihood distinctions based on satellite-indicated points of deep convection within environments favorable for storm development. We seek an approach that can be used to estimate climatological hailstorm frequency and risk throughout the historical satellite data record.

This presentation demonstrates that statistical distributions of convective parameters from satellite and reanalysis show separation between non-severe/severe hailstorm classes for predictors including overshooting cloud top temperature and area characteristics, convective available potential energy, vertical wind shear, 500 hPa temperature, mid-level lapse rate, precipitable water, and convective inhibition. These complex, multivariate predictor relationships are exploited within a DNN to produce a hail likelihood metric with a critical success index of 0.504 and Heidke skill score of 0.403, which is exceptional among recent analogous hail studies. Furthermore, applications of the DNN to select case studies demonstrate good qualitative agreement between hail likelihood and MESH. These hail classifications are aggregated across an 11-year GOES-12/13 image database to derive a hail frequency and severity climatology, which denotes the Central Plains, the Midwest, and northwestern Mexico as being the most hail-prone regions within the domain studied. Opportunities for training and applying DNN-based hailstorm predictions to recently developed GOES-8/10/12/13/16 and Meteosat Second Generation convective storm detection and characterization climatologies over South America and South Africa, respectively, will also be presented.
A modeling case study of a severe hail storm in complex topography
Authors: Brennan Killian P. , Sprenger Michael , Arpagaus Marco , Walser André , Wernli Heini
Published: March 2023

On the 28th of June 2021, a supercell traversed the complex topography of Switzerland. While propagating over a distance of 350 km and lasting 8 hours, the cell produced severe hail with diameters up to 9 cm. A case study is performed, aimed at understanding the development of the supercell environment, and the physical processes associated with the cell’s initiation, intensification, propagation, and dissipation. To this end, ensemble hindcast simulations are conducted with a convection-resolving numerical weather prediction model (COSMO-1E) coupled to a one-dimensional hail growth parameterization (HAILCAST). The simulation setup is identical to the operational ensemble forecasts performed at MeteoSwiss. Object-based analysis of the simulated hail cell is facilitated by a tracking algorithm, developed specifically to address the many challenges associated with tracking hail storms in output from numerical simulations. The hail cell tracks enable a storm-relative analysis of the storm environment and the temporal evolution of the storm structure during its phases of development. The inflow of air feeding the storm updraft is investigated with the aid of Lagrangian air parcel trajectories initiated along the hail track, giving novel insights into the low-level flow and moisture sources of the storm. All ensemble members produce thunderstorms comparable to the observed storm in terms of track position and intensity. However, the observations and the simulations differ with respect to initiation location and the lifetime of the cell. The analysis focuses on the intensification and dissipation stages of the storm, and especially how and why the cell tracks in the ensemble members differ from each other.
Severe convection event in southeast of Bulgaria on 17th September 2022
Authors: Kostashki Bilyana , Penchev Rosen , Guerova Guergana
Published: March 2023

The Knowledge of the development of the severe thunderstorms is crucial for improvement of weather forecasts which are provided to air traffic control (ATC) units. Intense thunderstorms, strong winds and hazards such as severe turbulence and icing, lightning activity, microbursts, and hail are very important for the aviation safety.

The present work focuses on the study case of atmospheric conditions preceding and during the development of unusual severe convection over southeast Bulgaria on 17th September 2022. when the squall line passed through the airport of Burgas bringing a lot of damage to the airport and surrounding towns.

On this days the weather was dominated by the presence of a very unstable air mass over Southeast Bulgaria, ahead of the atmospheric frontal zone. As convection continued its development, it moved east/northeast forward Burgas with overshooting cloud top height up to 14 km, cloud top temperature of -70C and maximum radar reflectivity of 60 dBz. In the late afternoon the process led to formation of gust front that reached the Burgas airport with the record for the past 50 years wind speed exceeding 45 m/s that damaged the mast of the airport's instrument landing system. At the same time heavy rain and intense lighting activity are reported. For analysis of the severe weather conditions are used weather satellite, radar and lightning data, Mode-S aircraft wind data and surface observations. In addition, information provided by the ground based Global Navigation Satellite System (GNSS) network is used. Integrated water vapor shows a sharp increase several hours before the convection developed. As moisture is one of the main ingredients for intense thunderstorms formation, GNSS tropospheric products are used together with other surface data to help the process of deep convection monitoring and forecasting.
Empirical Relationship between U.S. Tornado Outbreak Probabilities and the Large-scale Environment
Authors: Malloy Kelsey , Tippett Michael
Published: March 2023

Tornado outbreaks – when six or more tornadoes occur within a short period of time – are rare yet impactful events. It would be advantageous to understand how tornado outbreak activity varies on the subseasonal-to-seasonal (S2S) timescale. We examined the question of whether conditions favorable for outbreaks could be distinguished from those favorable for non-outbreak tornadoes. We have developed a 6-hourly tornado outbreak index, which uses logistic regression to relate the probability of a tornado outbreak at every grid point over the U.S. to collocated values of convective precipitation, storm relative helicity (SRH), and convective available potential energy (CAPE). Storm report data from the Storm Prediction Center is used to train the model and evaluate its performance. We found that this tornado outbreak index represents the climatology, seasonal cycle, and interannual variability of tornado outbreak activity well. Overall, greatest skill of the index is exhibited over regions and seasons when tornado outbreaks occur most often, especially in the Tennessee River Valley and Southeast U.S. for late winter and spring. In terms of reliability, the index performs well for probability forecasts up to 10% but is overconfident for forecasts greater than 10%. We found that the El Niño-Southern Oscillation (ENSO) modulates the tornado outbreak index values via its influence on precipitation, SRH, and CAPE patterns. Therefore, ENSO may be a valuable source of S2S predictability for tornado outbreak activity.
Polarimetric signatures of severe convective storms in Lake Victoria: from waterspouts to downbursts in the tropics!
Authors: del Moral Méndez Anna , Weckwerth Tammy M. , Wilson James W. , Roberts Rita D.
Published: March 2023

Lake Victoria is the largest freshwater lake in Africa, supporting the livelihood of more than 5 million people subsisting on its prosperous fishing industry and agriculture. However, the lake’s surrounding complex topography and geographic location makes this one of the deadliest regions of the world when it comes to weather-related accidents. It is estimated that more than 1,000 fishermen die yearly due to high waves produced by severe convective wind phenomena. Furthermore, severe hailstorms and flood-producing heavy rain events have increased in recent years in the extended East Africa (EA) regions, unfortunately also reporting several fatalities. 

In 2017, the World Meteorological Organization (WMO) launched the 3-year “High impact weather lake System” (HIGHWAY) project, with the main objective to reduce the loss of lives and goods in the lake basin and to improve resilience for the local communities. The project included a field campaign in 2019 to provide forecasters with high-resolution observations and to study the storm life cycle on the lake basin, with the utilization of S- and C-band dual-polarization radars in the surrounding countries. In this study, we use the high spatiotemporal resolution radar data from the field campaign in 2019 to investigate severe convection over the lake. We analyze two severe storms affecting the south and north shores of the lake (Tanzania and Uganda, respectively), identifying polarimetric signatures indicating severe weather, and testing the current capabilities of the radars’ scanning strategies. The results presented here are part of the ongoing high impact weather forecasting trainings and advancement efforts for East African countries towards the WMO Early Warning and Early Action 2025 goal, with a joint effort between WMO-led international projects, the National Center for Atmospheric Research, international non-profit organizations, and the National Meteorological and Hydrological Services in EA countries.
Toward the definition of “Medicane”
Authors: Miglietta Mario Marcello ,   COST Action on Mediterranean cyclones - initiative on the definition of Medicanes
Published: March 2023

As part of the EU COST Action on Mediterranean cyclones, an initiative was launched aimed at defining “Medicane”, a portmanteau for Mediterranean hurricane. In the literature, the term Medicane has been adopted in different ways, depending on the purpose of the study and the instrument adopted for the analysis. The purpose of this activity is to converge towards a shared definition, which will be able to bring together the numerical and satellite approach, the meteorological and climatological perspectives in a single and complete vision.

Although there is still no consensus on the definition, Medicanes are generally considered to be baroclinic cyclones that evolve into vortices with structural characteristics similar to tropical cyclones, i.e., axisymmetric, deep warm core with a windless center surrounded by strong winds. The synergy between baroclinic instability and diabatic processes is fundamental for the intensification of Medicanes.

Stimulating discussions emerged in some online meetings and in the subsequent debate. While up to now the term Medicane has been used for both cyclones with tropical characteristics and for weaker subtropical cyclones, a certain consensus has been reached in considering the latter category as separate, considering the different convective cloud cover, the fact that a significant part of the energy is received from baroclinic sources and that the area with maximum wind is farther from the center.
Comparison of hail detection techniques using dual-pol radar observations in Belgium
Authors: Watelet Sylvain , Delobbe Laurent , Reyniers Maarten
Published: March 2023

In the frame of a Belgian project aiming at improving the hydrometeors classification near the ground through the use of radar observations, two dual-pol classification schemes and a single-pol one including hail are tested and compared with crowd-sourced observations. The first scheme is based on the work of Keenan (2003) and is a supervised method making use of fuzzy logic while the second one is a semi-supervised method designed by Besic et al. (2016) that includes clustering as well as fuzzy logic. The single-pol scheme follows the Waldvogel method and is the current operational method used at the Royal Meteorological Institute of Belgium (RMIB). The crowd-sourced observations are collected through the smartphone application of the RMIB. This application was released in 2019 and allows every user to report the real-time weather, including the occurrence of hail and its size. We will present the validation scores and analyse the behaviour of the three methods for several hail storms. The uncertainties will be discussed, not only related to the three classification schemes but also to the users’ reporting behaviour and the scarcity of the hail events. Finally, the short term perspectives of further improvement of the hydrometeors classification will be given.
Trends of thunderstorm activity and relation to large-scale atmospheric conditions in western and central Europe
Authors: Augenstein Markus , Mohr Susanna , Kunz Michael
Published: March 2023

Thunderstorms associated with severe weather phenomena such as heavy rainfall, wind gusts, hail, tornados or lightning frequently cause considerable damage across the globe. In light of climate change, it is generally anticipated that the increase in thermal instability due to an increase in low-level temperature and moisture leads to more and more intense thunderstorms, thus increasing the risk from convective storms. However, previous studies have shown high annual and interannual variability of thunderstorm frequency in Europe related to large-scale atmospheric processes and mechanisms such as blocking or teleconnection patterns.

To investigate the relationship between large-scale atmospheric conditions and local-scale thunderstorms and their temporal changes, as well as, their long-term trends, we used cloudto-ground (CG) lightning measurements in western and central Europe from 2001 to 2021 (summer half-year; EUCLID network), representing a spatially and temporally homogeneous dataset. Surprisingly, trend analyses of this dataset show a large contiguous area with significantly decreasing trends from central France to Belgium and the Eifel region in Germany – for both lightning activity and thunderstorm days (defined as at least 5 lightning strokes on a 10 x 10 km² grid). In contrast, significant positive trends occur in northern Spain and some parts of the Balkans. However, in other regions of Europe, the observed trends are not significant due to high annual variability.

Further analyses suggest a relation between large-scale flow characteristics and thunderstorm activity in different regions of Europe. For example, based on odds ratio analyses, episodes with negative values of the North Atlantic Oscillation (NAO) Index are associated with decreasing thunderstorm activity in the above mentioned region (France to Germany). We observed that negative NAO phases, which have occurred more frequently over the last decade, may be an explanation for the negative trends in lightning activity and thunderstorm days.

In addition, we present a new algorithm for the temporal and spatial clustering of CG lightning based on ST-DBSCAN (Spatial-Temporal Density-Based Spatial Clustering of Applications with Noise). This algorithm also filters lightning in low-density regions and thus allows for the detection of contiguous areas of high lightning activity (clustered convective events, CCE). Initial analysis of the newly generated dataset shows that in recent years the number of CCEs with small spatial extent has increased, whereas the number of CCEs with large spatial extent has decreased.

This paper presents the work we conducted for the estimation of strong ground motion and building damage distributions after the 6 February 2023, Kahramanmaraş – Türkiye M7.7 Earthquake. The following outcomes were made available to the research community within the 18 hours of the earthquake occurrence and updated on a daily basis: Maps of the spatial distributions of peak ground acceleration and velocity, spectral accelerations at 0.2s and 1.0s, instrumental intensity and, number of damaged buildings distributions at regional and urban scale. The ground motion distribution maps with different ground motion and intensity prediction equations were re-produced and further improved with the incorporation of recorded strong motion data. Damage estimations were also updated based on the new ground motion inputs.
Four-century history of land transformation by humans in the United States (1630–2020): annual and 1 km grid data for the HIStory of LAND changes (HISLAND-US)
Authors: Li Xiaoyong , Tian Hanqin , Lu Chaoqun , Pan Shufen
Published: March 2023

Abstract. The land of the conterminous United States (CONUS) has
been transformed dramatically by humans over the last four centuries through
land clearing, agricultural expansion and intensification, and urban sprawl.
High-resolution geospatial data on long-term historical changes in land use
and land cover (LULC) across the CONUS are essential for predictive
understanding of natural–human interactions and land-based climate
solutions for the United States. A few efforts have reconstructed historical
changes in cropland and urban extent in the United States since the
mid-19th century. However, the long-term trajectories of multiple LULC
types with high spatial and temporal resolutions since the colonial era
(early 17th century) in the United States are not available yet. By
integrating multi-source data, such as high-resolution remote sensing
image-based LULC data, model-based LULC products, and historical census
data, we reconstructed the history of land use and land cover for the
conterminous United States (HISLAND-US) at an annual timescale and 1 km × 1 km spatial resolution in the past 390 years (1630–2020). The results show
widespread expansion of cropland and urban land associated with rapid loss
of natural vegetation. Croplands are mainly converted from forest, shrub,
and grassland, especially in the Great Plains and North Central regions.
Forest planting and regeneration accelerated the forest recovery in the
Northeast and Southeast since the 1920s. The geospatial and long-term
historical LULC data from this study provide critical information for
assessing the LULC impacts on regional climate, hydrology, and
biogeochemical cycles as well as achieving sustainable use of land in the
nation. The datasets are available at https://doi.org/10.5281/zenodo.7055086 (Li et al., 2022).
Porting the WAVEWATCH III (v6.07) wave action source terms to GPU
Authors: Ikuyajolu Olawale James , Van Roekel Luke , Brus Steven R. , Thomas Erin E. , Deng Yi , Sreepathi Sarat
Published: March 2023

Abstract. Surface gravity waves play a critical role in several processes, including mixing, coastal inundation, and surface fluxes. Despite the growing literature on the importance of ocean surface waves, wind–wave processes have traditionally been excluded from Earth system models (ESMs) due to the high computational costs of running spectral wave models. The development of the Next Generation Ocean Model for the DOE’s (Department of Energy) E3SM (Energy Exascale Earth System Model) Project partly focuses on the inclusion of a wave model, WAVEWATCH III (WW3), into E3SM. WW3, which was originally developed for operational wave forecasting, needs to be computationally less expensive before it can be integrated into ESMs. To accomplish this, we take advantage of heterogeneous architectures at DOE leadership computing facilities and the increasing computing power of general-purpose graphics processing units (GPUs). This paper identifies the wave action source terms, W3SRCEMD, as the most computationally intensive module in WW3 and then accelerates them via GPU. Our experiments on two computing platforms, Kodiak (P100 GPU and Intel(R) Xeon(R) central processing unit, CPU, E5-2695 v4) and Summit (V100 GPU and IBM POWER9 CPU) show respective average speedups of 2× and 4× when mapping one Message Passing Interface (MPI) per GPU. An average speedup of 1.4× was achieved using all 42 CPU cores and 6 GPUs on a Summit node (with 7 MPI ranks per GPU). However, the GPU speedup over the 42 CPU cores remains relatively unchanged (∼ 1.3×) even when using 4 MPI ranks per GPU (24 ranks in total) and 3 MPI ranks per GPU (18 ranks in total). This corresponds to a 35 %–40 % decrease in both simulation time and usage of resources. Due to too many local scalars and arrays in the W3SRCEMD subroutine and the huge WW3 memory requirement, GPU performance is currently limited by the data transfer bandwidth between the CPU and the GPU. Ideally, OpenACC routine directives could be used to further improve performance. However, W3SRCEMD would require significant code refactoring to make this possible. We also discuss how the trade-off between the occupancy, register, and latency affects the GPU performance of WW3.
Analogue modelling of the inversion of multiple extensional basins in foreland fold-and-thrust belts
Authors: Molnar Nicolás , Buiter Susanne
Published: March 2023

Abstract. The presence of pre-existing rheological heterogeneities in the lithosphere
plays a significant role during subsequent stages of deformation in
essentially every geological process. Extensional basins located in foreland
fold-and-thrust belts will alter the spatio-temporal evolution of its
associated orogen. It remains unclear how far horizontal stresses can act
and reactivate extensional structures due to their intrinsic irregular
patterns of deformation deflection and localisation. Overprinting events and
relative dating uncertainties in the geological record make it difficult to
interpret how stresses were transferred across a heterogeneous crust. Here
we examine the inversion of extensional basins in foreland fold-and-thrust
belts by using three-dimensional analogue experiments that simulate first an
extensional stage, followed by a shortening stage. Our results show how
extensional basins proximal to the orogenic front effectively localise
deformation in the shape of thrusts and prevent stress transfer beyond their
location. Basins that are located at large distances from the orogenic front
also show evidence of mild inversion at early stages but are characterised only
by basin infill contraction and uplift. When multiple extensional basins are
present, the degree and type of inversion will depend primarily on their
relative location and distance to the orogenic front. Here we also prove
that the presence of additional extensional features in the vicinity of a
basin can be a first-order controlling factor in their overall reactivation
history. We share additional insights of how a fold-and-thrust belt evolves
once the extensional basins have been incorporated by the advancing wedge,
and we provide comparisons with natural examples that shed light on some
still unanswered questions related to the process of basin inversion in
orogenic belts.
Identifying and characterising blood biomarkers associated with migraine risk
Authors:   , Mesrian Tanha Hamzeh
Published: March 2023

Genetic studies for migraine have identified genetic risk variants and shown that significant proportion of variance in migraine occurrence in a population is due to genetic variants. Similarly, genetic variants contribute to blood biomarkers levels. This PhD aimed to use genetic data to identify blood biomarkers associated with the risk of migraine. The results associated migraine to multiple lipids and suggested a causally protective role for a longer fatty acid length against migraine. This thesis also found 58 new migraine-associated proteins and genes and showed that 5 of those could represent novel therapeutic tools for the treatment against migraine.

Published: March 2023

In Angola, coronary artery disease (CAD) has increased in prevalence in recent years. This study aims to evaluate the additional value of the coronary calcium score (CCS) to conventional risk factors (CRF) in predicting the presence of CAD. Results: This study comprises 204 patients. The mean age was 56.46±9.19 years. 123(60.3%) patients are male. The patients with CAD are older (mean age 56.00±9,4 years vs. 59.83±6.8 years, p=0.017), had higher proportion of men [20(83.3%) vs. 103(57.2), p=0.014], diabetes [10(41.7%) vs. 37(20.6%), p=0.021], dyslipidemia [23(95.8%) vs. 108(60.0%], p=0.001) smoking in the past, [9(37.5%) vs 27(15.0%), p=0.007], higher number of risk factors (NRF) (p 0.001), and higher Agatston CCS (p<0.001). A logistic regression was performed to ascertain the effect age CRF, NRF, and CCS on the likelihood that participants have CAD. Based on the Backward conditional method after step 5, we identified that NFR and CCS variables added statistically significantly to the prediction (p<0.05). We identified increasing NFR (B= 0.583, Wald 5.086; OR 1.791: p=0-0024 95%CI =1.07-2.97) and CCS (B= 0.016, Wald 30.951; OR 1.016: p<0.001 95% CI =1.01-1.02) were associated with an increased likelihood of exhibiting significant CAD. Conclusion: The NRF and the CCS proved to be strong predictors of CAD.

Published: March 2023

To analyze the correlation between the occurrence of vertebral artery ostium stenosis (VAOS) and the severity of osteoporosis in elderly patients with atherosclerosis (AS), and disclose the physiopathologic mechanism of the correlation between VAOS and osteoporosis. 120 patients were divided into two groups. The baseline data of both groups were collected. The biochemical indicators of patients in both groups were collected. The EpiData database was established to enter all the data into the database for statistical analysis. There were significant differences in the incidence of dyslipidemia among risk factors of cardia-cerebrovascular disease (P<0.05). LDL-C, Apoa and Apob were significantly lower than the control group (P<0.05). BMD, T-value and Ca in the observation group were significantly lower than the control group, while BALP and serum phosphorus in the observation group were significantly higher than the control group (P<0.05). The more severe the VAOS stenosis, the higher the incidence of osteoporosis, and there was a statistical difference in the risk of osteoporosis among different VAOS stenosis degrees (P<0.05). Apolipoprotein A, B and LDL-C in blood lipids are important factors affecting the development of bone and artery diseases. There is a significant correlation between VAOS and the severity of osteoporosis.

There were 3 major anesthesia methods for discectomy: local, epidural and general. A lot of studies has been established to compare these three methods in different aspects, however, the result is still controversial. We conducted this network meta-analysis to evaluate these methods. Electronic databases including PubMed, EMBASE, Cochrane Library, were searched to identify clinical trials that reported the effects of local anesthesia general anesthesia and epidural anesthesia in lumbar disc herniation. Three indicators were included for evaluation: post-operative VAS score, complication, operation duration. In total, 12 studies and 2287 patients were included for this study. For complication, epidural anesthesia shows significantly lower rate compare to general anesthesia (OR: 0.45, 95% CI [0.24, 0.45], P=0.015), but local anesthesia didn’t show significant result, no significant heterogeneity was observed between designs. For VAS score, epidural anesthesia showed a better effect (MD: -1.61, 95%CI [-2.24, -0.98]) compare to general anesthesia, and local anesthesia has a similar effect (MD: -0.91, 95%CI [-1.54, -0.27]). However this result showed a very high heterogeneity (I2=95%). For operation duration, local anesthesia showed a significant lesser time compare to general anesthesia (MD: -46.31(minutes), 95%CI [-73.73, -19.19]) but epidural anesthesia didn’t have one, this result also showed a very high heterogeneity (I2=98%). Epidural anesthesia showed lesser post- operative complication compare to general anesthesia in lumbar disc herniation surgery.

The purpose of this study is to examine the effect of Adansonia digitata seed oil on hair damaged by bleaching. Experimental materials were prepared by treating damaged hair that had been bleached 3 times in the following 4 ways. 1) Treatment base (T0), 2) 3% Adansonia digitata seed oil treatment (T3), 3) 7% Adansonia digitata seed oil treatment (T7), 4) 3% silicone oil treatment (S3). The effect analysis before and after treatment of bleached hair was carried out in the following way. First, to measure the damaged hair, that is, to measure the porosity, the hair to be damaged was placed in a methylene blue solution. Second, to test the dynamic properties of hair, tensile strength and yield strength were measured. Finally, to observe the changes in the morphological structure of the hair surface, electric field emission scanning electron microscopy (FE-SEM) images were employed. The absorbance measurement using methylene blue showed a decrease in the average in hairs dyed with 3% and 7% of Adansonia digitata seed oil, indicating that there was a hair improvement effect in hairs dyed with Adansonia digitata seed oil. As a result of studying whether the hair bleached containing Adansonia digitata seed oil has the effect of improving hair quality, the absorption strength decreased and the tensile strength increased. In addition, absorbance measurement, gloss measurement, and FE-SEM experiments were conducted. As a result, It was confirmed that there is an effect of improving hair quality in terms of the constant arrangement of cuticles on the hair surface and increasing the gloss of the hair. It was found that Adansonia digitata seed oil, a natural ingredient, has a high effect on improving hair quality of dyed hair in order to minimize damage to bleached hair. As a result of this research, it is expected that various products will be developed using Adansonia digitata seed oil.
