Authors: Indah Frisca , Susilowati Tri 
Published: September 2022

Latar Belakang:dismenorea merupakan rasa nyeri yang terjadi pada perut bagian bawah yang berlangsung selama 2-3 hari dimulai sehari sebelum mulai menstruasi. Menurut Fatmawati (2016), bahwa kejadian dismenorea di Jawa Tengah pada umumnya 56%. Tingginya prevalensi dismenorea dipengaruhi oleh riwayat kesehatan keluarga dismenorea, siklus menstruasi yang berkepanjangan, kualitas tidur, kurangnya aktivitas fisik seperti olahraga secara teratur. Dampak dari dismenorea itu sendiri yaitu dapat menimbulkan gangguan dalam proses belajar mengajar dikelas, sehingga siswi tersebut akan membatasi aktivitas sehari-harinya terutama aktivitas belajar disekolahnya. Menurut Alimuddin (2017), bahwa siswi yang mengalami kesuitan belajar karena efek dismenorea sebanyak 73,4% dan siswi yang tidak terganggu dalam aktivitas belajarnya sebesar 26,6% Tujuan Penelitian : untuk mendeskripsikan gambaran dismenorea saat aktivitas belajar dikelas pada siswi SMA Muhammadiyah 1 Sragen. Metode Penelitian:menggunakan metode kuantitatif dengan desain deskriptif. Penentuan sampel dengan menggunakan metode simple random sampling (sampel acak sederhana) sebanyak 113 siswi dari jumlah populasi sebanyak 138 siswi. Data yang dikumpulkan dengan menggunakan NRS (Numeric Rating Scale) dan kuesioner aktivitas belajar. Data disajikan dalam bentuk distribusi frekuensi. Hasil penelitian : menunjukkan sebagian besar responden berusia 17 tahun sebanyak 41 siswi (36,3%), usia pertama haid sebagian besar berusia 11 tahun sebanyak 69 siswi (61,6%), lama perdarahan haid 6-8 hari sebanyak 64 siswi (56,6%), sebagian besar responden mengalami dismenorea sedang berjumlah 62 siswi (54,9%) dan sebagian besar responden yang aktivitas belajarnya terganggu sebanyak 72 siswi (63,7%). Kesimpulan: adanya gambaran dismenorea saat aktivitas belajar dikelas pada siswi SMA Muhammadiyah 1 Sragen. Diharapkan pada penelitian ini dapat menjadi informasi bagi siswi yang mengalami dismenorea saat melakukan aktivitas belajar dan dapat mengatasi cara mengurangi rasa nyeri haid.

Abstract
Evidence of a relation between the mass accretion rate and the disk mass is established for young, Class II pre-main-sequence stars. This observational result opened an avenue to test theoretical models and constrain the initial conditions of disk formation, fundamental in the understanding of the emergence of planetary systems. However, it is becoming clear that planet formation starts even before the Class II stage, in disks around Class 0 and I protostars. We show for the first time evidence for a correlation between the mass accretion rate and the disk mass for a large sample of Class I young stars located in nearby (<500 pc) star-forming regions. We fit our sample, finding that the Class I object relation has a slope flatter than Class II stars, and the former have higher mass accretion rates and disk masses. The results are put in context of disk evolution models.
Cooling Envelope Model for Tidal Disruption Events
Authors: Metzger Brian D. 
Published: September 2022

Abstract
We present a toy model for the thermal optical/UV/X-ray emission from tidal disruption events (TDEs). Motivated by recent hydrodynamical simulations, we assume that the debris streams promptly and rapidly circularize (on the orbital period of the most tightly bound debris), generating a hot quasi-spherical pressure-supported envelope of radius R

∼ 1014 cm (photosphere radius ∼1015 cm) surrounding the supermassive black hole (SMBH). As the envelope cools radiatively, it undergoes Kelvin–Helmholtz contraction R

, envelope heating from fallback accretion is subdominant compared to the envelope cooling luminosity except near optical peak (where they are comparable). Envelope contraction can be delayed by energy injection from accretion from the inner envelope onto the SMBH in a regulated manner, leading to a late-time flattening of the optical/X-ray light curves, similar to those observed in some TDEs. Eventually, as the envelope contracts to near the circularization radius, the SMBH accretion rate rises to its maximum, in tandem with the decreasing optical luminosity. This cooling-induced (rather than circularization-induced) delay of up to several hundred days may account for the delayed onset of thermal X-rays, late-time radio flares, and high-energy neutrino generation, observed in some TDEs. We compare the model predictions to recent TDE light-curve correlation studies, finding both agreement and points of tension.

Taberna 2 de Mirobriga (Santiago do Cacém, Portugal): adaptações artesanais e domésticas e evolução ceramológica, nos séculos V e VI d. C.
Authors: Quaresma José Carlos 
Published: September 2022

Este articulo discute dos grandes cuestiones. La primera es la evolución arquitectónica de un espacio comercial desde la época imperial hasta el periodo visigótico, cronología de cerca de cinco siglos en los cuales ha tenido funciones comerciales, posteriormente artesanales y finalmente habitacionales. La segunda cuestión es el análisis estratigráfico, tecnológico y estadístico de la cerámica común (local o regional), en particular en un período aún poco investigado estratigráficamente en el territorio actualmente portugués: la primera mitad del siglo VI d. C. Esta línea de investigación sigue otros trabajos desarrollados en Mirobriga, aplicándose propuestas de datación por comparación estadística con los datos estratigráficos de otras áreas peninsulares, como Lisboa y Madrid.

Antropología europea, refugio y género. Una aproximación al reglamento de Dublín
Authors: Forina Alessandro 
Published: September 2022

El presente trabajo se sitúa en el ámbito de la antropología europea analizando el refugio desde una perspectiva de género. Partiendo de la relación histórica entre la antropología y los Refugee Studies (Estudios de Refugiados), este artículo examina el «refugio» y las políticas de asilo de la Unión Europea desde una perspectiva de género. En este contexto, los Estudios de Refugiados han visto un importante aumento e interés en los análisis de género y feministas sobre la configuración del refugio. Sin embargo, los estudios centrados en las políticas de asilo europeas desde una perspectiva antropológica de género son escasos. En este sentido, el objetivo principal de este trabajo es analizar etnográficamente desde una perspectiva de género estas políticas. Fruto de una investigación cuya metodología ha seguido una aproximación etnográfica en el colectivo ciudadano Red Solidaria de Acogida en Madrid, se presentan algunos resultados en el ámbito de las políticas de asilo europeas, en concreto en el análisis del Reglamento de Dublín desde una perspectiva de género.

Published: September 2022

Age, growth and maturation in the mesopelagic squid Abralia andamanica (Cephalopoda: Enoploteuthidae) were studied in 140 individuals of 15-60 mm dorsal mantle length (DML) captured from open waters in the southeast Arabian Sea. The length-weight relationship was estimated as W=0.278 DML1.884 (R2=0.93). Age estimates based on statolith increment counts ranged from 79 to 177 days, suggesting a short (<200-day) lifespan. Growth in length was best described by a linear function for males and a power function for females. Growth in weight was best described by a power function for both sexes. Growth rates of the DML ranged from 0.16 to 0.30 (mean=0.24) mm/day in males and from 0.23 to 0.43 (mean=0.33) mm/day in females. The hatching season extended from June to August (monsoon season).
La prise en compte du temps en chimie
Authors: Reisse Jacques 
Published: September 2022

Le chimiste s’intéresse à des problèmes qui relèvent de la chimie de l’environnement ou encore à cette phase remarquable de la transformation de la matière qui correspond au passage du non-vivant au vivant, il est obligé de prendre en compte le « temps de l’histoire ». Il est intéressant d’examiner comment le chimiste réagit face à cette obligation lui qui, par sa culture et contrairement au géologue par exemple, n’est pas préparé à devoir tenir compte d’un temps qui ne soit pas un simple paramètre permettant d’ordonner des observations de manière reproductible.
Connaissances et expériences ordinaires des dérèglements climatiques
Authors: Durand Séverine , Granjou Céline , Mounet Coralie 
Published: September 2022

Documenté et mis en évidence par un savoir expert peu accessible au non spécialiste, le changement climatique est perçu comme un phénomène global, à distance de l’expérience vécue de l’environnement et du temps qu’il fait. A rebours de cette connaissance globale, cet article s’intéresse aux évolutions du climat que les habitants et pratiquants de milieu montagnard (massif des Écrins) identifient et expérimentent par leur biais de leurs pratiques. Il met en évidence des savoirs expérientiels portant certes sur la dimension climatique fortement médiatisée (en particulier, fonte des glaciers, éboulements, etc.) mais également sur tout un pan de conséquences locales peu décrites par ailleurs et portant sur le paysage, la faune, la flore, etc. Intimement liés à la dimension sensible et émotionnelle de la relation de ces pratiquants au milieu, ces savoirs expérientiels les amènent à développer certains bricolages adaptatifs pour ajuster et transformer leurs pratiques. Mais parce que ces évolutions ne sont pas documentées par les sciences du climat, la légitimité de leurs observations n’est pas évidente. Or, l’expérimentation sensible, porteuse d’affects, et la connaissance de ces « dérèglements » tangibles dans un lieu particulier paraissent essentielles pour construire les décisions et l’action politique d’atténuation et d’adaptation au changement climatique.

A trio reclaiming blackness and black spirituality: A tribute to Vuyani Vellem
Authors: Mpofu Buhle , Molopyane Lethabo M. 
Published: September 2022

Issues related to racism are still pervasive in global society; and Blackness has dominated identity politics in the South African political and public debates since the downfall of apartheid. Recently, there have been questions on whether skin colour can be used as a generalised indication of being previously disadvantaged with some arguing that skin colour cannot be used as a condition for empowerment. They argue that socio-economic conditions must rather be used as the criteria for empowerment. This contribution draws on the notions of Liminality (Turner) and Third Space (Bhabha) to investigate how the lives of three black intellectuals – Steve Biko, Tambudzo Marechera, Vuyani Vellem – resembled the ‘liminal threshold’ as they underwent ‘initiation’ on black identity. The authors conclude that despite the many years of ‘chanting down Babylon’, black people still have to contend with white supremacy in the same way that Tambudzo Marechera, Steve Biko and more recently, Vuyani Vellem, fiercely challenged it.Contribution: This study is a contribution to keeping the legacy of Vuyani Vellem alive by highlighting the notions of Liminality and Third Space to demonstrate how the lives of the three black intellectuals resembled the ‘liminal threshold’ as they all underwent ‘initiation’ on black identity in their respective times and contexts.
COVID-19 and diabetic ketoacidosis: A case series at an urban district hospital in South Africa
Authors: Dicks Heather N. , Naidoo Keshena 
Published: September 2022

Background: Coronavirus disease 2019 (COVID-19) is associated with an increased prevalence and mortality from diabetic ketoacidosis (DKA) globally. With limited access to specialised care, most patients with DKA in South Africa are managed at district hospital level. This study describes the profile of patients admitted to a district hospital in South Africa with DKA and COVID-19 and examines associated risk factors encountered.Methods: This was a case series of all patients presenting to a district hospital with DKA and COVID-19 infection between July 2020 and July 2021. Data extracted included patients’ demographic profiles, biochemical results, comorbidities and clinical outcomes.Results: The median age of the 10 patients admitted during the study period was 39 years old (±12), six of whom were male. The hemoglobin A1c (HbA1c) values on admission ranged from 9.7 to 13.8. Five of the patients had pre-existing type 2 diabetes mellitus (DM). Four of the known DM patients were on metformin only, and one was on biphasic insulin. Three patients had other pre-existing comorbidities, two patients with hypertension and one with human immunodeficiency virus (HIV). Three patients demised, two of whom were hypoxic on admission.Conclusion: Diabetic ketoacidosis appears more commonly in COVID-19 infected patients with type 2 DM and at a young age. Suboptimal glycaemic control was associated with DKA, and hypoxia was a strong predictor for mortality. Treatment inertia was evident in the known DM group, who were on monotherapy despite persistent hyperglycaemia. Greater vigilance is required to detect ketosis in type 2 DM and intensify therapy to improve glycaemic control.
Investigation of chitosan, its depolymerized products, and nanoformulation as novel anticonvulsants
Authors: Aboutabl Mona E. , Fayed Bahgat , Ismail Shaymaa A. 
Published: September 2022

Objectives
Chitosan is a natural biopolymer that possesses various biological activities. The aim of the current study was to evaluate the potentiality of chitosan and its enzymatically depolymerized products as anticonvulsants.

Materials and methods
In the current study, chitosan enzymatic depolymerization was carried out using Bacillus cereus chitosanase followed by fractionation of the produced chitooligosaccharides. Phase I anticonvulsant activity of chitosan as well as its enzymatically depolymerized products was evaluated using pentylenetetrazole-induced seizures, maximal electric shock, and neurotoxicity tests. In phase II, median effective dose, median toxic dose, and protective index were determined. In addition, γ-aminobutyric acid brain level and acute toxicity were evaluated.

Results and conclusion
The results indicated that the fraction with the lower degree of acetylation and longer chains of glucosamine (COSH) possessed rapid onset of action with the highest protection (75%) at 0.5 h and long-acting effect for 4 h. In addition, the median effective dose of COSH was 12.7-fold more potent than the reference ethosuximide, whereas in the maximal electric shock test, COSH showed lower potency than phenytoin. The median toxic dose was 1.4-fold and 7.9-fold higher than ethosuximide and phenytoin, respectively. The protective index was 18.1-fold and 3.98-fold higher than ethosuximide and phenytoin, respectively, with a significant increase in γ-aminobutyric acid neurotransmitter brain level. In an attempt to prolong the anticonvulsant effect of COSH, a nano-formulation was carried out in which the particle size was estimated as 188.7±0.26 nm. After that, an equivalent dose of a combined treatment of COSH and the nanoformula (each 15 mg/kg) was evaluated in which a prolonged effect was achieved up to 24 h.

Published: September 2022

Background & objectives:
Data from the National Clinical Registry for COVID-19 (NCRC) were analyzed with an aim to describe the clinical characteristics, course and outcomes of patients hospitalized with COVID-19 in the third wave of the pandemic and compare them with patients admitted earlier.

Methods:
The NCRC, launched in September 2020, is a multicentre observational initiative, which provided the platform for the current investigation. Demographic, clinical, treatment and outcome data of hospitalized COVID-19 patients were captured in an electronic data portal from 38 hospitals across India. Patients enrolled during December 16, 2021 to January 17, 2022 were considered representative of the third wave of COVID-19 and compared with those registered during November 15 to December 15, 2021, representative of the tail end of the second wave.

Results:
Between November 15, 2021 and January 17, 2022, 3230 patients were recruited in NCRC. Patients admitted in the third wave were significantly younger than those admitted earlier (46.7±20.5 vs. 54.6±18 yr). The patients admitted in the third wave had a lower requirement of drugs including steroids, interleukin (IL)-6 inhibitors and remdesivir as well as lower oxygen supplementation and mechanical ventilation. They had improved hospital outcomes with significantly lower in-hospital mortality (11.2 vs. 15.1%). The outcomes were better among the fully vaccinated when compared to the unvaccinated or partially vaccinated.

Interpretation & conclusions:
The pattern of illness and outcomes were observed to be different in the third wave compared to the last wave. Hospitalized patients were younger with fewer comorbidities, decreased symptoms and improved outcomes, with fully vaccinated patients faring better than the unvaccinated and partially vaccinated ones.

Authors: Owoade IA , Wuraola F , Olasehinde O , Akinyemi P A , Randolph K , Dare AJ , Kingham TP , Alatise OI 
Published: September 2022

Background:
Cancers are a disease of growing public health importance in Africa, but cancer research capacity in the region is underdeveloped. The quest to foster and promote locally conceptualized and conducted oncology research in Africa have informed the African Research Group for Oncology's (ARGO) research capacity-building efforts in Nigeria.

Aim:
To evaluate the effectiveness of oncology research capacity-building initiatives among Nigerian senior trainees and junior faculty physicians.

Subjects and Methods:
Panel study design was employed to study Nigerian senior trainees and junior faculty physicians who participated in two research capacity-building symposia. Data were collected pre-and immediate post-symposia, and 3-month post-first symposium. Changes in knowledge were assessed using the Chi-square test and confidence levels using the Wilcoxon signed rank test. A P value of <0.05 was considered statistically significant.

Results:
In the first symposium, the participants' pass rate in the knowledge-based questions improved from 9.8% to 46.7% to 81.5% at the baseline, immediate post-symposium, and 3-month post-symposium, respectively (P < 0.001). Likewise, the participants' confidence level in carrying out certain research-related activities increased after the second symposium (P < 0.001).

Conclusion:
The study concludes that building capacity for oncology research in low- and middle-income countries is possible with focused symposia and educational programs.
Hyperlipidemia and Its Relation with Tinnitus
Authors: Musleh A , Alshehri S , Qobty A 
Published: September 2022

Background:
Tinnitus is a common auditory complaint among individuals characterized by ringing, buzzing, hissing, chirping, whistling, or other sounds in the ear. Following a low-fat/low-cholesterol diet can help reduce the blood cholesterol and triglyceride levels, which aids improvement in tinnitus symptoms. High cholesterol and triglyceride levels in the bloodstream play a significant role in the development of tinnitus, hearing loss, and vertigo.

Aim:
This paper aims to test the association between hyperlipidemia and tinnitus among outpatients in King Khalid University (KKU) ENT clinic.

Patients and Methods:
A retrospective review of the medical records of patients who attended the ENT clinic at KKU was performed. An otological examination including pure tone audiometry, personal habits, and lipid profile was conducted. Patients were contacted by phone if there were any missing data.

Results:
The study included 300 patients who were treated in the outpatient clinic during the study period. About 80% of the patients were of age >45 years and 60.3% were males. Half of the cases (150 cases) had tinnitus and 13% had hyperlipidemia. Patients with high lipid profile recorded doubled risk for tinnitus (P < 0.05). Other risk factors found to be significantly associated with tinnitus include vertigo, young age, and wearing an earpiece.

Conclusions:
In conclusion, there was a significant association between hyperlipidemia and the incidence of tinnitus even after adjusting for all other risk factors. More large-scale researches are needed to assess in detail the association between different lipid components such as low-density lipoprotein, high-density lipoprotein, triglycerides, and tinnitus epidemiology.
