Abstract
Nuell, S, Illera-Domínguez, V, Carmona, G, Macadam, P, Lloret, M, Padullés, JM, Alomar, X, and Cadefau, JA. Hamstring muscle volume as an indicator of sprint performance. J Strength Cond Res 35(4): 902–909, 2021—This study aimed to compare mechanical properties and performance during sprinting, as well as thigh muscle volumes (MVs), between national-level sprinters and physically active males. In addition, the relationships between thigh MVs and sprint mechanical properties and performance were investigated. Seven male sprinters and 9 actives performed maximal‐effort 40-m sprints. Instantaneous velocity was measured by radar to obtain theoretical maximum force (F0), the theoretical maximum velocity (V0), and the maximum power (Pmax). For MV assessment, series of cross-sectional images of each subject's thigh were obtained by magnetic resonance imaging for each of the quadriceps and hamstring muscles and the adductor muscle group. Sprinters were faster over 10 m (7%, effect size [ES] = 2.12, p < 0.01) and 40 m (11%, ES = 3.68, p < 0.01), with significantly higher V0 (20%, ES = 4.53, p < 0.01) and Pmax (28%, ES = 3.04, p < 0.01). Sprinters had larger quadriceps (14%, ES = 1.12, p < 0.05), adductors (23%, ES = 1.33, p < 0.05), and hamstrings (32%, ES = 2.11, p < 0.01) MVs than actives. Hamstrings MV correlated strongly with 40-m sprint time (r = −0.670, p < 0.01) and V0 (r = 0.757, p < 0.01), and moderately with Pmax (r = 0.559, p < 0.05). Sprinters were significantly faster and had greater V0 and Pmax than active males. Larger MVs were found in sprinters' thighs, especially in the hamstring musculature, and strong correlations were found between hamstring MV and sprint mechanical properties and sprint performance.

Abstract
Botek, M, Krejčí, J, McKune, A, Valenta, M, and Sládečková, B. Hydrogen rich water consumption positively affects muscle performance, lactate response, and alleviates delayed onset of muscle soreness after resistance training. J Strength Cond Res 36(10): 2792–2799, 2022—Positive outcomes of hydrogen rich water (HRW) supplementation on endurance performance have been shown, but the effects of HRW in resistance training are unclear. The aim of this study was to assess the effects of 1,260 ml of HRW intake on physiological, perceptual, and performance responses to a resistance training and after 24 hours of recovery. This randomized, double-blinded placebo-controlled cross-over study included 12 men aged 23.8 ± 1.9 years. Subjects performed a half squat, knee flexion, and extension exercises with the load set at 70% of 1 repetition maximum for 3 sets (10 reps/set). Lunges were performed with a load of 30% of body mass for 3 sets (20 reps/set). Time of each set, lactate, and ratings of perceived exertion were assessed mid-way through exercise and immediately after the exercise. Creatine kinase, muscle soreness visual analog scale ratings, countermovement jump, and heart rate variability were evaluated before the training and at 30 minutes, 6, and 24 hours of recovery. Lunges were performed faster with HRW compared with placebo (p < 0.001). Hydrogen rich water reduced lactate at mid-way and immediately after the exercise (HRW: 5.3 ± 2.1 and 5.1 ± 2.2, placebo: 6.5 ± 1.8 and 6.3 ± 2.2 mmol·L−1, p ≤ 0.008). Visual analog scale ratings were significantly lower with HRW (26 ± 11 vs. 41 ± 20 mm, p = 0.002) after 24 hours of recovery. In conclusion, an acute intermittent HRW hydration improved muscle function, reduced the lactate response, and alleviated delayed onset of muscle soreness.

Abstract
Ishida, A, Bazyler, CD, Sayers, AL, Mizuguchi, S, and Gentles, JA. Acute effects of match-play on neuromuscular and subjective recovery and stress state in Division I collegiate female soccer players. J Strength Cond Res 35(4): 976–982, 2021—The purpose of this study was to investigate acute effects of match-play on neuromuscular performance and subjective recovery and stress state and the relationship between training load (TL) and changes in neuromuscular performance in female soccer players. Twelve National Collegiate Athlete Association Division I players participated (20.7 ± 2.3 years; 64.4 ± 7.2 kg; 164.5 ± 6.0 cm) and completed countermovement jump (CMJ) at 0 kg (CMJ0) and 20 kg (CMJ20) and the Short Recovery Stress Scale (SRSS) at 3 hours pre-match (Pre), 12 hours post-match (Post12), and 38 hours post-match (Post38). Countermovement jump variables included body mass, jump height (JH), modified reactive strength index (RSI), peak force (PF), relative PF, eccentric impulse, concentric impulse (CI), peak power (PP), relative PP (RPP), eccentric average PP, and concentric average power (CAP). The SRSS consists of 4 Stress Scales (SSs) and 4 Recovery Scales (RSs). Training loads included total distance, total PlayerLoad, high-speed running, and session ratings of perceived exertion. Significant moderate to large decreases were observed from Pre to Post12 in JH, RSI, CI, PP, RPP, and CAP in CMJ0 and CMJ20 (p < 0.05, effect size [ES] = 0.63–1.35). Significant changes were observed from Pre to Post12 in all RSs (p < 0.05, ES = 0.65–0.79) and 3 SSs (p < 0.05, ES = 0.71–0.77). Significant correlations were observed between CMJ20 PP from Pre to Post12 and all TLs (p < 0.05, r = −0.58 to −0.68). CMJ0 and CMJ20 JH and PP may indicate acute neuromuscular changes after match-play. The magnitude of CMJ20 PP decrements from Pre to Post12 may be affected by soccer match-play volumes.

The potential of large-scale, non-invasive prospection methods has been widely recognized in archaeology in recent years. Their outstanding possibilities for the exploration of urban centres have been realised early on and applied at selected sites. The ‘ArchPro Carnuntum’ project stands out for its extensive investigation of a Roman provincial capital by the combined application of a wide variety of survey methods (aerial archaeology, magnetometry, ground penetrating radar, extensive field survey) resulting in detailed information on the ancient infrastructure of the Roman metropolis. Within the project, it was not only possible to discover new settlement areas, but in some cases even to deduce their former purpose. As a result, the military administrative centre, newly built residential areas, and temporary military camps could be detected in the archaeological landscape of Carnuntum. This paper presents an overview of the results of this internationally unique prospection project.Az elmúlt évek során széles körben felismerték a régészet tudományterületén alkalmazható nagyszabású, nem invazív jellegű kutatási módszerekben rejlő potenciált. A módszer települési központok feltárásának területén alkalmazható lehetőségei már korán valósággá váltak, és alkalmazásra kerültek a kiválasztott helyszíneken. Az „ArchPro Carnuntum” projekt a római provinciális főváros átfogó vizsgálatával a legkülönfélébb felmérési módszerek (légi régészet, magnetometria, földradar, kiterjedt terepi felmérés) együttes alkalmazásával kiemelkedik ezek közül, és részletes információval szolgál a római város antik infrastruktúrájával kapcsolatban. A projekt során nem kizárólag új települési területek felfedezésére nyílt mód, hanem egyes esetekben következtetni lehetett a területek egykori funkciójára is. Mindezek eredményeként a carnuntumi régészeti területen kimutathatóvá vált a katonai igazgatási központ, valamint az új építésű lakónegyedek és az ideiglenes katonai táborhelyek is. Jelen tanulmány ezen nemzetközi szinten is egyedülálló kutatási projekt eredményeiről nyújt áttekintést.

Published: February 2021

AbstractBackground and aimsEven though the Compulsive Sexual Behavior Disorder (CSBD) was added to the ICD-11 under the impulse control category in 2019, its neural mechanisms are still debated. Researchers have noted its similarity both to addiction and to Obssesive-Compulsive Disorder (OCD). The aim of our study was to address this question by investigating the pattern of anatomical brain abnormalities among CSBD patients.MethodsReviewing 39 publications on Diffusion Tensor Imaging (DTI) we have identified main abnormalities specific for addictions and OCD. Than we have collected DTI data from 36 heterosexual males diagnosed with CSBD and 31 matched healthy controls. These results were then compared to the addiction and OCD patterns.ResultsCompared to controls, CSBD individuals showed significant fractional anisotropy (FA) reduction in the superior corona radiata tract, the internal capsule tract, cerebellar tracts and occipital gyrus white matter. Interestingly, all these regions were also identified in previous studies as shared DTI correlates in both OCD and addiction.Discussion and conclusionsResults of our study suggest that CSBD shares similar pattern of abnormalities with both OCD and addiction. As one of the first DTI study comparing structural brain differences between CSBD, addictions and OCD, although it reveals new aspects of CSBD, it is insufficient to determine whether CSBD resembles more an addiction or OCD. Further research, especially comparing directly individuals with all three disorders may provide more conclusive results.
The Effect of Declustering on the Size Distribution of Mainshocks
Authors: Mizrahi Leila , Nandan Shyam , Wiemer Stefan 
Published: February 2021

AbstractDeclustering aims to divide earthquake catalogs into independent events (mainshocks), and dependent (clustered) events, and is an integral component of many seismicity studies, including seismic hazard assessment. We assess the effect of declustering on the frequency–magnitude distribution of mainshocks. In particular, we examine the dependence of the b-value of declustered catalogs on the choice of declustering approach and algorithm-specific parameters. Using the catalog of earthquakes in California since 1980, we show that the b-value decreases by up to 30% due to declustering with respect to the undeclustered catalog. The extent of the reduction is highly dependent on the declustering method and parameters applied. We then reproduce a similar effect by declustering synthetic earthquake catalogs with known b-value, which have been generated using an epidemic-type aftershock sequence model. Our analysis suggests that the observed decrease in b-value must, at least partially, arise from the application of the declustering algorithm on the catalog, rather than from differences in the nature of mainshocks versus fore- or aftershocks. We conclude that declustering should be considered as a potential source of bias in seismicity and hazard studies.

AbstractPortugal, located in the southwest region of the Eurasian plate, has been affected by several destructive earthquakes throughout its history, the most well-known being the 1755 Great Lisbon earthquake. The seismicity of the territory, both in the mainland and in the Azores and Madeira islands, has prompted the continuous development of seismic monitoring, from the first known macroseismic inquiry, following the 1755 Great Lisbon earthquake, to the current state-of-the-art seismic network. Once scattered in separate efforts, at present, most seismic stations in Portugal relay its data to a common data center, at Instituto Português do Mar e da Atmosfera, where data are automatically processed for the downstream generation of both manually revised and automatically generated products and services. In this article, we summarize the evolution of the permanent seismic network, its current status, the products and services that are publicly available, a recent effort of rapid deployment of a dense network following a mainshock, and state-of-the-art ocean-bottom seismometer developments.

Published: February 2021

Background: Micro-incision vitrectomy surgery otherwise called minimally invasive vitrectomy surgery (MIVS) is undoubtedly one of the most impressive evolutions in the surgical retina field of the past decade. This self-healing suture less procedure is safe and reliable with rapid visual recovery. The present study enlightens the visual outcome following MIVS for rhegmatogenous retinal detachment.Methods: This prospective study was done in 68 patients who underwent MIVS for rhegmatogenous retinal detachment. A detailed ocular examination of the patients undergoing MIVS was done. Outcome of the surgery was assessed in terms of functional and anatomical success after one week, 6 weeks and third month.Results: Of the 68 patients, maximum number of patients was in the age group of 51-60 years. Risk factors were previous cataract surgery in 28%, lattice degeneration in 26%, trauma in 22%, myopia in 18% and no specific risk factors in 6%. Mean preoperative BCVA was log MAR 2.16±0.37 and mean post-operative BCVA was log MAR 1.22±0.35 with p value of <0.001 on paired t test indicating the difference was statistically significant. Functional success was achieved in 58% and anatomical success in 94% patients.Conclusions: Visual outcome following MIVS was good for rhegmatogenous retinal detachment. Secondary glaucoma and development or progression of cataract was found to be the major complication following MIVS. MIVS is a suture less safe surgery facilitating early visual recovery and associated with minimal complications.

An adnexal mass is a common clinical presentation in gynecological practice. Differential diagnosis of an adnexal mass can vary from a life threatening emergency like ectopic gestation to a malignant lesion with a high mortality rate, so it poses diagnostic challenge for treating gynecologist.To study the histopathological nature of adnexal masses.110 cases of adnexal masses who underwent surgical intervention during the study period of one year were included in the study. Specimen received in the department of Pathology and was subjected to histopathological examination.A total of 110 cases formed the study group. In our study 79% of cases of adnexal masses had an ovarian origin, 15.45% cases were of tubal origin and 5.45% cases had combined pathology i.e due to tubovarian abscess and endometriosis. Among Ovarian lesions 9.1% had non neoplastic cyst like corpus luteal cyst or endometriosis whereas 50% cases had a surface epithelial lesion. 77 cases out of a total of 110 were ovarian in origin, out of which 57(74%) were benign, 05(6.5%) were borderline and 15(19.5%) were malignant.To conclude, adnexal mass often poses a diagnostic dilemma to the treating physician. Ectopic gestation is often a cause of adnexal mass among patients of reproductive age group. Ovarian neoplasm constitute another major cause of adnexal mass, serous cyst adenoma is the commonest benign lesion seen while serous cyst adenocarcinoma is the commonest malignant ovarian lesion.

Anaemia is a critical global health problemA good morphological subtyping of anaemia can guide clinician in further patient management. With the advent of automation, red cell and platelet indices are available from the routinely used blood cell counters in the laboratory, these supplemented with peripheral smear examination help in a good categorization of anaemia. Aim of this study is to study the morphological types of anaemias in the adults with the Objectives of Categorization of the anaemias based on morphology and to study the distribution of the red cell and platelet indices in the same.: It was a prospective study conducted in the hematology wing of our central diagnostics over a period of three months and a total of 520 cases, which were morphologically classified according to the analyzer indices and peripheral smear. Distribution of the red cell and platelet indices in the different categories of anaemia were also noted. A majority of the anaemias were microcytic hypochromic in type (67.1%) followed by normocytic normochromic anaemias (26.5%). Increased RDW was seen in microcytic hypochromic anaemias (55%) and normocytic normochromic anaemias (6.9%). The Mean platelet count/ mean platelet volume was increased in microcytic anaemias compared to others. : Anaemias in the rural set up are predominantly of the microcytic in type. A good knowledge of the variation in RBC indices, RDW and platelet /mean platelet volume ratio along with a peripheral smear can help the reporting haematologist identify early stages of iron deficiency anaemia and can give a precise and accurate anaemia categorization at the basic entry level of laboratory investigation. Interpretation of variation in RBC and platelet indices though often neglected can contribute significantly to categorize the anaemia.

One of the main detrimental consequences of blood transfusion is donor-to-recipient infection transfer. Serological tests before transfusion may help to minimise TTIs. The purpose of this research was to establish the prevalence of TTIs among volunteer and blood donors.Records from the blood bank attached to a tertiary care center were analysed. Past of 3 years records were entered and analysed through epi info 7.In present study, the prevalence of blood-borne infection among blood donors was 2.12%. HIV incidence was 0.52% and HBV, HCV and Syphilis 0.68%. 0.11%, respectively, and 0.81%. Replacement donor has a rate of 11.41% relative to voluntary donor of 0.70%.Blood door selection procedure must be comprehensive, utilising traditional procedures. Blood preservation is the recipient's primary concern. Furthermore, community motivation and knowledge campaigns are needed to raise volunteer blood donors.

Published: February 2021

Gastric carcinomas rank 5th among all the cancers in India. The incidence increases with age and peaks during 5th to 7th decades. The most common location is gastric antrum followed by the lesser curvature. Her2 neu expression is reported as a frequent molecular abnormality in gastric adenocarcinomas associated with poor prognosis. The main aim was to study clinicopathological parameters of gastric carcinomas and study expression of HER2 in gastric adenocarcinomas. This was a 4-year cross-sectional observational retrospective and prospective study of 47 cases of gastric carcinomas. The clinical profile and pathological features were studied. HER2 expression in gastric adenocarcinomas was scored according to Hoffman system and its association with age, gender, histopathological type, grade was studied. FISH was done in cases of equivocal HER2/Neu expression.Of the total 47 gastric carcinomas, it was most commonly found in antrum. Mean age of presentation was 59.4 years with male: female ratio of 1.4:1. Of total 47 adenocarcinomas, 22 were tubular, 4 cases each of papillary and mixed adenocarcinoma and 17 were poorly cohesive carcinoma. There were 5 cases of grade I, 27 grade II and 15 grade III carcinomas. HER2 positivity was seen in 10 cases, 5 were equivocal and 32 were HER2 negative. We found statistically significant correlation between HER2 expression with histopathological grade (P=0.003) and age (P=0.014).Tubular adenocarcinoma was the common subtype and antrum was the commonest location. HER2 expression was significantly associated with grades and age in cases of gastric adenocarcinomas. This study helped us to know the trends of gastric carcinoma in our region. Use of immunohistochemistry and fluorescent in situ hybridization techniques additionally supports the use of targeted therapeutic modalities.
