Abstract
Dirty fireballs are a hypothesized class of relativistic massive-star explosions with an initial Lorentz factor Γinit below the Γinit ∼ 100 required to produce a long-duration gamma-ray burst (LGRB), but which could still produce optical emission resembling LGRB afterglows. Here we present the results of a search for on-axis optical afterglows using the Zwicky Transient Facility (ZTF). Our search yielded seven optical transients that resemble on-axis LGRB afterglows in terms of their red colors (g − r > 0 mag), faint host galaxies (r > 23 mag), rapid fading (dr/dt > 1 mag day−1), and in some cases X-ray and radio emission. Spectroscopy of the transient emission within a few days of discovery established cosmological distances (redshift z = 0.876 to 2.9) for six of the seven events, tripling the number of afterglows with redshift measurements discovered by optical surveys without a γ-ray trigger. A likely associated LGRB (GRB 200524A, GRB 210204A, GRB 210212B, and GRB 210610B) was identified for four events (ZTF 20abbiixp/AT 2020kym, ZTF 21aagwbjr/AT 2021buv, ZTF 21aakruew/AT 2021cwd, and ZTF 21abfmpwn/AT 2021qbd) post facto, while three (ZTF 20aajnksq/AT 2020blt, ZTF 21aaeyldq/AT 2021any, and ZTF 21aayokph/AT 2021lfa) had no detected LGRB counterpart. The simplest explanation for the three “orphan” events is that they were regular LGRBs missed by high-energy satellites owing to detector sensitivity and duty cycle, although it is possible that they were intrinsically subluminous in γ-rays or viewed slightly off-axis. We rule out a scenario in which dirty fireballs have a similar energy per solid angle to LGRBs and are an order of magnitude more common. In addition, we set the first direct constraint on the ratio of the opening angles of the material producing γ-rays and the material producing early optical afterglow emission, finding that they must be comparable.

Abstract
We present the photometry of 16 91T/99aa-like Type Ia Supernovae (SNe Ia) observed by the Las Cumbres Observatory. We also use an additional set of 21 91T/99aa-like SNe Ia and 87 normal SNe Ia from the literature for an analysis of the standardizability of the luminosity of 91T/99aa-like SNe. We find that 91T/99aa-like SNe are 0.2 mag brighter than normal SNe Ia, even when fully corrected by the light-curve shapes and colors. The weighted rms of the 91T/99aa-like SNe (with z
CMB > 0.01) Hubble residuals is 0.25 ± 0.03 mag, suggesting that 91T/99aa-like SNe are also excellent relative distance indicators to ±12%. We compare the Hubble residuals with the pseudo-equivalent width (pEW) of Si ii
λλ6355 around the date of maximum brightness. We find that there is a broken linear correlation between those two measurements for our sample including both 91T/99aa-like and normal SNe Ia. As the

pEW
max

(Si ii
λλ6355) increases, the Hubble residual increases when

pEW
max

(Si ii
λλ6355) < 55.6 Å. However, the Hubble residual stays constant beyond this. Given that 91T/99aa-like SNe possess shallower Si ii lines than normal SNe Ia, the linear correlation at

pEW
max

(Si ii
λλ6355) < 55.6 Å can account for the overall discrepancy of Hubble residuals derived from the two subgroups. Such a systematic effect needs to be taken into account when using SNe Ia to measure luminosity distances.
Lepto-hadronic Jet-disk Model for the Multiwavelength SED of M87
Authors: Boughelilba Margot , Reimer Anita , Merten Lukas 
Published: October 2022

Abstract
The low-luminosity active galactic nuclei M87, archetype of Fanaroff–Riley I radio galaxies, was observed in a historically quiet state in 2017. While one-zone leptonic jet models alone cannot explain the core radio-to-gamma-ray spectrum, we explore a hybrid jet-disk scenario. In this work, we model the overall spectral energy distribution of M87's core with a dominating one-zone lepto-hadronic jet component, coupled with the contribution from the accretion flow. We find close-to-equipartition parameter sets for which the jet component fits the radio-to-optical data as well as the gamma-ray band, while the accretion flow mainly contributes to the X-ray band. The effects of gamma-ray absorption by the extragalactic background light during the propagation toward Earth are probed and are found to be negligible for this model. The neutrino flux produced by such scenarios is also calculated, but remains below the current instruments’ sensitivity.
A New Approach to Kinetic Energy Flux at the Different Frequencies above the IRIS Bright Points*
Authors: Sadeghi Rayhane , Tavabi Ehsan 
Published: October 2022

Abstract
Various bright structures abound in the chromosphere playing an essential role in the dynamics and evolution therein. Tentatively identifying the wave characteristics in the outer solar atmosphere helps to understand this layer better. One of the most significant aspects of these characteristics is the wave phase speed (PS), which is a dominant contribution to solar coronal heating and energy distribution in the Sun’s atmosphere layers. To obtain energy flux (EF), it is necessary to calculate the filling factor (FF) and the PS. In this study, the FF was determined by tracking the size and intensity of the IRIS bright points (BPs). To estimate an accurate PS and EF, it is necessary to know the chromosphere and transition region (TR) thickness and the phase difference between the two desired levels. Chromosphere and TR thickness cannot be measured directly on the disk; this study is performed using spectral data and calibrated based on Doppler velocities. As a result, the PSs in active regions (ARs) and coronal holes (CHs), as well as the IRIS BPs, have been calculated using the cross-power wavelet transform of Doppler velocities. Consequently, about the CH, the PS mean values are from 40 to 180 km s−1 at the network and from 30 to 140 km s−1 at the internetwork; and about the AR, they are from 80 to 540 km s−1 at the network and 70 to 220 km s−1 at the internetwork. Finally, the EF for the IRIS BPs has been calculated in three different frequencies. The results indicate that the network BPs have an influential role in heating the higher layers, while in the internetwork BPs most of the energy returns to the lower layers.
The Origin and Distance of the High-velocity Cloud MI
Authors: Schmelz J. T. , Verschuur G. L. 
Published: October 2022

Abstract
The high-velocity, neutral hydrogen feature known as MI may be the result of a supernova that took place about 100,000 yr ago at a distance of 163 pc. Low-velocity H i data show a clear cavity, a structure indicative of regions evacuated by old exploding stars, centered on the spatial coordinates of MI, (l, b) = (165°, 65.°5). The cavity is also visible in 100 μm dust data from IRAS. The invisible companion of the yellow giant star, 56 Ursae Majoris, may be the remains of the supernova that evacuated the cavity and blasted MI itself outward at 120 km s−1. The mass and energy of MI are easily in line with what is expected from a supernova. The diffuse X-rays seen by ROSAT provide evidence of a hot cavity, and the enhanced X-rays may result from the subsequent bow shock.

Challenges to Online Pharmacy Classes during COVID 19 Pandemic: cross sectional study in Jordan
Authors: Salama Ali , Altaif Khalil 
Published: October 2022

Background: Covid 19 pandemic has had a strong influence on all aspects of life . One of these influence is education. The academic authorities in Jordan as in elsewhere across the world have shifted their method of teaching to online class. After four semester of online teaching it’s important for both teaching staff and students of pharmacy faculties to assess the trends and the preference of students to different methods of online teaching. The purpose of this study was to assess the influence of the COVID19 pandemic on online education for pharmacy students in Jordan’s faculties of pharmacy.
Methods: We emailed a survey to the majority of students in Jordan’s pharmacy faculties during january and february 2022.
Results: We received 230 responses, with 87.2 percent of respondents being female and the majority of the students being pharmacy students. Among the 230 respondents, 75% said they liked combining online and face-to-face training, while 13% said they preferred face-to-face instruction and only 12% said they favored online learning. The major challenges in online teaching during the pandemic are issues with in-person communication (87 percent), student assessment (65 percent) and use of technology tools (35 percent).
Conclusion: Due to the fact that the survey was conducted during the fourth semester with the COVID 19 pandemic, and most students have gained confidence in using online technology and the university IT support, one can conclude that pharmacy students have a high level of confidence in the effectiveness of online pharmacy education.
La « remarquable famille Schreber » : une histoire de père en fils et ses exégètes
Authors: Gavarini Laurence 
Published: October 2022

Avec « La remarquable famille Schreber », l’auteure revisite les lectures qui ont constitué durant un siècle le cas Schreber comme paradigmatique de la paranoïa, depuis celles de Freud et Lacan, jusqu’au tournant interprétatif des années 1960-1980 qui élargit la problématique de la folie du sujet à l’éducation familiale et plus précisément paternelle, justifiant le sous-titre : « une histoire de père en fils et ses exégètes ». Centrée initialement sur l’étude d’une pathologie, son origine événementielle, son étiologie et sa préhistoire médicale, la focale de l’étude du cas Schreber se déplace et s’élargit à ce qui fait délirer un sujet (l’état psychique d’un père, son éducation tyrannique). Ainsi, des tendances épistémologiques dans la clinique du « cas Schreber » rivalisent, selon qu’elles imputent la causalité psychique à la gouverne du sujet et à la faillite du Nom-du-Père ou à une causalité externe, à la croisée du transgénérationnel et des orientations éducatives du père, symbole d’une « pédagogie noire » fortement dénoncée en Allemagne et dans l’aire anglo-saxonne depuis les années 1970. L’article passe en revue ces différentes lectures et en questionne les manques, particulièrement la fonction des femmes dans la remarquable famille.
Du cas Schreber et de ce qu’on ne doit pas oser faire dans l’éducation : une contribution au débat sur la transmission
Authors: de Lajonquière Léandro , Baldassi D’Arrigo Floriana 
Published: October 2022

En un moment historique où la demande adressée aux experts en éducation et formation est de plus en plus présente sous une forme réductionniste et médicalisante, le « cas Schreber » permet de repenser les conditions de possibilité de l’éducation d’un enfant. S’il est souvent mobilisé pour montrer les méfaits d’une éducation qualifiée d’autoritaire, pour nous, il est plutôt l’occasion de montrer les risques délétères des initiatives prétendument scientifiques en éducation, structurées autour du déni de la castration, dont son seul témoignage est la condition nécessaire pour qu’un enfant soit convoqué à habiter un lieu de parole singulier dans une histoire en cours.

Depuis sa découverte, la pratique de la vaccination s’est améliorée de façon continue afin d’offrir une meilleure efficacité et tolérance. Les réactions locales voire diffuses sont souvent évoquées, mais aucune étude ne rapporte de résultats en fonction du bras choisi pour l’injection. Nous avons réalisé une étude observationnelle prospective aux centres de vaccination COVID-19 du GHT des Landes pendant trois semaines. Un questionnaire était remis après la deuxième injection et évaluait les douleurs et gênes du patient lors de la première injection. Durant cette période, 2 797 patients ont reçu leur deuxième injection, 2 487 ont répondu au questionnaire dont 2 301 sont exploitables. La vaccination a été réalisée à 81 % du côté du bras non dominant et à 19 % du côté du bras dominant. Les douleurs/gênes locales ont été rapportées par 47 % des patients sur les deux bras, leur apparition étant survenue le jour même pour la moitié des personnes et le lendemain pour l’autre moitié, avec une intensité moyenne de 3,3 sur une échelle de 10. Les douleurs/gênes diffuses étaient présentes chez 19 % des personnes, quel que soit le côté. Le choix du bras pour l’injection semble ne pas avoir d’influence sur la survenue de douleurs.

Published: October 2022

Objective:
To compare the benefits of enhanced recovery after surgery (ERAS) pathways with traditional pathways for adult patients undergoing laparoscopic appendectomy.

Methods:
We looked for publications using the keywords “Enhanced Recovery After Surgery,” “Fast-track Surgery,” “Laparoscopic Appendectomy,” and “Laparoscopic Appendicectomy” in PubMed/Medline, Embase, and the Cochrane library. Operative time, lesser length of stay, oral intake timing, readmission rate, pain/satisfaction levels, readmission rate, and surgical site infections were recorded and analyzed.

Results:
A total of 95 articles from registers and 161 articles from databases were identified. Three eligible studies were included. The ERAS pathways had a lesser length of stay [Z=2.06, MD= -1.05, 95% CI=(-2.04, -0.05), P=0.04] and an earlier start to postoperative feeds [Z=6.22, MD= -267.49, 95% CI=(-351.80, -183.19), P<001].

Conclusions:
ERAS pathways have a shorter length of stay and earlier postoperative feed initiation for adult patients undergoing laparoscopic appendectomy compared with standard care. Both approaches have similar operative time, surgical site infection incidence, and readmission rate.

Authors: Tontu Furkan , Asar Sinan , Oren Bilgin Beyza 
Published: October 2022

Objective:
To investigate the effect of the variability of Nas, Cls, Ks, lactate values and sodium effect (NaEffect), chloride effect (ClEffect), non-lactate strong ion difference (SIDnl) values calculated according to Stewart’s approach on predicting intensive care unit (ICU) mortality.

Methods:
The study was conducted on 1539 patients, retrospectively. Serum Na (Nas), serum Cl (Cls), serum K (Ks), serum Ca (Cas), serum Mg (Mgs), lactate, pH values and SIDnl, NaEffect, ClEffect, APACHE II (first, last), and SOFA (first, last) scores were recorded. Radiometer ABL 800 (Denmark) was used for blood gas analysis. The variability of each parameter was calculated. The effect of variability of each parameter on 30-day ICU mortality was analyzed.

Results:
The variability of lactate (P<0.001, OR=0.580, 95% CI=0.505-0.652), pH (P=0.001, OR=0.004, 95% CI=0.000-0.104), NaEffect (P<0.001, OR=0.550, 95% CI=0.378-0.592), Ks (P<0.001, OR=0.385, 95% CI=0.244-0.565) values were protective factors of ICU mortality and Cls value was a risk factor (P=0.004, OR=1.095, 95% CI=1.024-1.164). Variability of ClEffect, SIDnl values did not affect ICU mortality.

Conclusions:
The variability of electrolytes is important. Electrolyte, effects, and lactate variability can guide treatment and fluid applications in ICU.

Authors: Singhal Rishi , Cardoso Victor Roth , Ludwig Christian , Super Jonathan , Rajeev Yashasvi , Rudge Gavin , Gkoutos Georgios V. , Mahawar Kamal 
Published: October 2022

Introduction:
There is a paucity of data in the scientific literature on the morbidity and mortality of bariatric and metabolic surgery (BMS) in individuals suffering from Type 2 diabetes mellitus (T2D). The current study is a secondary analysis of the GENEVA dataset to understand this.

Materials and Methods:
Logistic regressions were performed to investigate the influence of diabetes on complication rates and procedure selection. Ethical approval was not required.

Results:
One thousand four hundred and seventy-five of these patients were suffering from T2D at the time of the surgery (416 diet-treated type 2 diabetes), 806 oral agent-treated type 2 diabetes, and 253 insulin-treated type 2 diabetes [ITD]). Six hundred and fifty (44.1%) of these patients underwent laparoscopic sleeve gastrectomy (LSG); 487 (33%) underwent Roux-en-Y gastric bypass; 230 (15.6%) underwent a one anastomosis gastric bypass (OAGB); and 108 (7.3%) underwent some other procedures. The 30-day mortality of BMS in those without T2D was 0.07% (4/5609) as compared to 0.4% (6/1475) and 0.8% (2/253) in those with T2D and ITD, respectively. 7.9% of those with T2D developed a 30-day complication compared to 6.5% without T2D (P = 0.0475). There was an increased risk of complications in patients with ITD on univariate and multivariate analysis. Patients with T2D were significantly less likely to undergo an LSG and significantly more likely to undergo an OAGB.

Conclusions:
ITD patients undergoing BMS experienced significantly higher 30-day morbidity and mortality. Although LSG was the most common procedure in patients with T2D, these patients were less likely to undergo LSG than patients without T2D.
Stereotactic radiosurgery of radioresistant glioblastomas. The ways of overcoming radioresistance of hypoxic tumors
Authors: Griazov A.B. , Griazov A.A. , Grydina N.Ya. , Stuley V.A. 
Published: October 2022

Background. Taking into account high degree of resistance of glioblastoma to radiation therapy, and also low overall survival rates of patients, it is necessary to develop improved methods of treating this pathology, in particular, complex combined treatment with radiation therapy and radiosensitizers.
Purpose – to assess the effectiveness of radiosensitization of hypoxic tumors in radiosurgical treatment of glioblastomas; to increase non-recurrent and overall survival rate of patients. Materials and methods. Stereotactic radiosurgery (SRS) of glioblastoma was performed in 106 patients (average age – 53 years), 66 males (62,26%) and 40 females (37,73%). The average dose was 18 Gy in a single-fraction SRS, and 32 Gy (7 Gy per fraction) in multi-fraction SRS. The average volume tumor was 29 cm3 . The treatment group consisted of 66 patients who underwent SRS with radiosensitization. 40 patients made up the control group and underwent SRS without radiosensitization.
Results. Median overall survival (MOS) was 20 months in the group with radiosensitization, whereas in the control group it was 12 months. 10-month recurrence-free period after radiosurgery was observed in 95,4% of the patients of the group with radiosensitization and in 70,6% of the patients of the control group. MOS after SRS was similar between the patients with wild-type IDH tumors and patients with tumors with IDH mutation (10,0 months and 11,0 months respectively), and also between the patients with MGMT-methylated tumors and patients with MGMT-nonmethylated tumors (11,2 and 10,2 months respectively). Among all the treated patients, in 20 of them (16,6%) side radiation effects after SRS were observed, and in 9 patients (7,5%) radiation necrosis developed in 3 to 16 months after SRS. The signs of moderate toxicity in the form of vomiting were observed in 6,6% of the patients of the subgroup with metronidazole. There were no signs of toxicity in the subgroup with nimorazole.
Conclusions. Radiosensitization improves rates of overall survival by 53,3% and recurrence-free survival by 24,8 % in performing SRS of hypoxic radioresistant glioblastomas. Nimorazole and metronidazole are powerful radiosensitizers which increase radiosensitivity of tumor cells through enhancing oxygen saturation of hypoxic cells. In order to determine indications for performing SRS with radiosensitization and periods for performing an SRS session we must take into consideration the result of an oxygen test (level of oxygen saturation of the tumor), the peak of signal intensity in the zone of active tumor growth and the peak of saturation of the whole tumor volume.
