Published: December 2021

Introduction. MRKH syndrome is characterized by incomplete or absent of vaginal and uterine agenesis. Currently there are no official guidelines on the management of MRKH syndrome. This case report is about the operative management in MRKH patients by neovaginal with laparoscopic Davydov procedure.
Case presentation. A 26-year-old woman admitted that she had never had a period, the patient admitted that her breasts began to grow at the age of 13, and the patient was planning to get married, and refused to take further planning. The patient then came back to the RSMH urogynecology clinic after marriage, from the examination it was found that the pubic hole was ± 0.5 cm deep, speculum examination could not be done, the uterus could not be palpable from the rectal toucher. From the ultrasound examination, it was found that both ovaries were within normal limits and suspected uterine hypoplasia. Hormone tests were within normal limits, with the following values: LH 27.01 mIU / mL, FSH 57.08 mIU / mL, Estradiol 10 pg / mL, Prolactin 5.94 ng / mL. Patients with a history of atrial septal defect (ASD) and ventricular septal defect (VSD)
Conclusion. Treatment of MRKH syndrome patients is usually complex and requires multidisciplinary counseling, therapy, and management, so it is hoped that it can help patients to make a functional vagina. Further research and collaboration from various multidisciplinary make pregnancy in patients with MRKH syndrome, not impossible, along with current technological and scientific developments, the selection of surrogate mothers, and uterine transplantation is an option.

Abstract
APOGEE is a high-resolution (R ∼ 22,000), near-infrared, multi-epoch, spectroscopic survey of the Milky Way. The second generation of the APOGEE project, APOGEE-2, includes an expansion of the survey to the Southern Hemisphere called APOGEE-2S. This expansion enabled APOGEE to perform a fully panoramic mapping of all of the main regions of the Milky Way; in particular, by operating in the H band, APOGEE is uniquely able to probe the dust-hidden inner regions of the Milky Way that are best accessed from the Southern Hemisphere. In this paper we present the targeting strategy of APOGEE-2S, with special attention to documenting modifications to the original, previously published plan. The motivation for these changes is explained as well as an assessment of their effectiveness in achieving their intended scientific objective. In anticipation of this being the last paper detailing APOGEE targeting, we present an accounting of all such information complete through the end of the APOGEE-2S project; this includes several main survey programs dedicated to exploration of major stellar populations and regions of the Milky Way, as well as a full list of programs contributing to the APOGEE database through allocations of observing time by the Chilean National Time Allocation Committee and the Carnegie Institution for Science. This work was presented along with a companion article, Beaton et al. (2021), presenting the final target selection strategy adopted for APOGEE-2 in the Northern Hemisphere.

Abstract
We validate the planetary nature of an ultra-short-period planet orbiting the M dwarf KOI-4777. We use a combination of space-based photometry from Kepler, high-precision, near-infrared Doppler spectroscopy from the Habitable-zone Planet Finder, and adaptive optics imaging to characterize this system. KOI-4777.01 is a Mars-sized exoplanet (R

p
= 0.51 ± 0.03R
⊕) orbiting the host star every 0.412 days (∼9.9 hr). This is the smallest validated ultra-short period planet known and we see no evidence for additional massive companions using our HPF RVs. We constrain the upper 3σ mass to M

p
< 0.34 M
⊕ by assuming the planet is less dense than iron. Obtaining a mass measurement for KOI-4777.01 is beyond current instrumental capabilities.
Bayesian Estimation of the D(p,γ)3He Thermonuclear Reaction Rate
Authors: Moscoso Joseph , de Souza Rafael S. , Coc Alain , Iliadis Christian 
Published: December 2021

Abstract
Big bang nucleosynthesis (BBN) is the standard model theory for the production of light nuclides during the early stages of the universe, taking place about 20 minutes after the big bang. Deuterium production, in particular, is highly sensitive to the primordial baryon density and the number of neutrino species, and its abundance serves as a sensitive test for the conditions in the early universe. The comparison of observed deuterium abundances with predicted ones requires reliable knowledge of the relevant thermonuclear reaction rates and their corresponding uncertainties. Recent observations reported the primordial deuterium abundance with percent accuracy, but some theoretical predictions based on BBN are in tension with the measured values because of uncertainties in the cross section of the deuterium-burning reactions. In this work, we analyze the S-factor of the D(p,γ)3He reaction using a hierarchical Bayesian model. We take into account the results of 11 experiments, spanning the period of 1955–2021, more than any other study. We also present results for two different fitting functions, a two-parameter function based on microscopic nuclear theory and a four-parameter polynomial. Our recommended reaction rates have a 2.2% uncertainty at 0.8 GK, which is the temperature most important for deuterium BBN. Differences between our rates and previous results are discussed.
26Aluminum from Massive Binary Stars. II. Rotating Single Stars Up to Core Collapse and Their Impact on the Early Solar System

Published: December 2021

Abstract
Radioactive nuclei were present in the early solar system (ESS), as inferred from analysis of meteorites. Many are produced in massive stars, either during their lives or their final explosions. In the first paper of this series (Brinkman et al. 2019), we focused on the production of 26Al in massive binaries. Here, we focus on the production of another two short-lived radioactive nuclei, 36Cl and 41Ca, and the comparison to the ESS data. We used the MESA stellar evolution code with an extended nuclear network and computed massive (10–80 M
⊙), rotating (with initial velocities of 150 and 300 km s−1) and nonrotating single stars at solar metallicity (Z = 0.014) up to the onset of core collapse. We present the wind yields for the radioactive isotopes 26Al, 36Cl, and 41Ca, and the stable isotopes 19F and 22Ne. In relation to the stable isotopes, we find that only the most massive models, ≥60 and ≥40 M
⊙ give positive 19F and 22Ne yields, respectively, depending on the initial rotation rate. In relation to the radioactive isotopes, we find that the ESS abundances of 26Al and 41Ca can be matched with by models with initial masses ≥40 M
⊙, while 36Cl is matched only by our most massive models, ≥60 M
⊙. 60Fe is not significantly produced by any wind model, as required by the observations. Therefore, massive star winds are a favored candidate for the origin of the very short-lived 26Al, 36Cl, and 41Ca in the ESS.
Wave-driven Mass Loss of Stripped Envelope Massive Stars: Progenitor-dependence, Mass Ejection, and Supernovae

Published: December 2021

Abstract
The discovery of rapidly rising and fading supernovae powered by circumstellar interaction has suggested the pre-supernova mass eruption phase as a critical phenomenon in massive star evolution. It is important to understand the mass and radial extent of the circumstellar medium (CSM) from theoretically predicted mass ejection mechanisms. In this work, we study the wave heating process in massive hydrogen-poor stars, running a suite of stellar models in order to predict the wave energy and pre-explosion timescale of surface energy deposition. We survey stellar models with main-sequence progenitor masses from 20–70 M
⊙ and metallicity from 0.002–0.02. Most of these models predict that less than ∼1047 erg is deposited in the envelope, with the majority of the energy deposited in the last week of stellar evolution. This translates to CSM masses less than ∼10−2
M
⊙ that extend to less than ∼1014 cm, too small to greatly impact the light curves or spectra of the subsequent supernovae, except perhaps during the shock breakout phase. However, a few models predict somewhat higher wave energy fluxes, for which we perform hydrodynamical simulations of the mass ejection process. Radiative transfer simulations of the subsequent supernovae predict a bright but brief shock-cooling phase that could be detected in some Type Ib/c supernovae if they are discovered within a couple days of explosion.

Published: December 2021

BACKGROUND: Reverse transcriptase-polymerase chain reaction (RT-PCR) is the primary diagnostic tool to confirm coronavirus disease 2019 (COVID-2019) due to its high specificity. However, it has relatively low sensitivity and time consuming. In contrast, chest computed tomography (CT) has high sensitivity and achieves quick results. It may, therefore, play a critical role in screening and diagnosing COVID-19. A cross-sectional study was done in 212 patients with confirmed cases and patients under surveillance for COVID-19 tested for RT-PCR and chest CT scan. Statistical analysis was performed using SPSS Version 23 (Statistical Package for the Social Sciences, IBM Corp., Armonk, NY, USA).

AIM: We aim to investigate the diagnostic value of chest CT in correlation to RT-PCR in Indonesia.

METHODS: A cross-sectional study was done in 212 patients with confirmed cases and patients under surveillance for COVID-19 tested for RT-PCR and chest CT scan. Statistical analysis was performed using SPSS Version 23 (Statistical Package for the Social Sciences, IBM Corp., Armonk, NY, USA).

RESULTS: From a total of 212 patients, 92% of them were diagnosed as confirmed cases of COVID-19. It was found that the sensitivity of CT scan for COVID-19 patients was 72.3% (65.5% and 78.5%) with positive predictive value (PPV) of 93.9% (90.9% and 96.0%) and the sensitivity and PPV improve in symptomatic patients. Typical chest CT scan lesions were 8.0 times which were more likely (3.9–16.4; p <0.001) to be detected in symptomatic patients while patients with severe CT scan findings were 4.4 times more likely (3.0–6.5; p <0.001) to be admitted to the intensive care unit.

CONCLUSION: A high PPV suggests that a chest CT scan can detect COVID-19 lesions, but the absence of the lesions would not exclude the disease’s presence.
Algunos rasgos de la biología de la abeja roja de los caracoles, Rhodanthidium sticticum (Fabricius, 1787): fenología, preferencia floral, uso de conchas, capacidad de vuelo y comportamiento territorial
Authors: Romero Daniel , Vargas Pablo , Ornosa Concepción 
Published: December 2021

La ecología y el comportamiento de la mayoría de las especies de abejas mediterráneas (fenología, comportamiento solitario o social, apareamiento, nidificación, especialización en plantas) son aún poco conocidos o no han sido descritos en profundidad, salvo para contadas especies. Tal es el caso de la abeja roja de los caracoles, Rhodanthidium sticticum (Hymenoptera, Megachilidae), una especie mediterránea, solitaria y territorial cuya biología ha sido tratada muy superficialmente. En este trabajo se describe su fenología, el uso que hace de conchas de caracol más allá de la nidificación, la polilectia y las plantas que visita, su capacidad de vuelo, la territorialidad y el apareamiento, todo ello basado en observaciones de campo propias. La biología de R. sticticum es parecida a la de otros Anthidiini, pero con particularidades. Es una especie primaveral, univoltina, muy activa en días soleados durante las horas centrales. Cuando las condiciones meteorológicas son adversas se refugia en el interior de conchas de caracol, pudiendo compartirlas varios individuos (de la misma especie o incluso de otras). A pesar de ser claramente poliléctica, muestra preferencia por plantas con flores melitófilas, en especial del género Antirrhinum. Los machos defienden sus territorios, tanto contra otros machos conespecíficos como interespecíficamente, con un comportamiento que permite asegurar su propio éxito reproductivo.
Sobre la larva de la luciérnaga ibérica endémica Photinus immigrans Zaragoza-Caballero & Viñolas, 2018 (Coleoptera, Lampyridae)
Authors: Rodríguez-Flores Paula C. , Recuero Ernesto 
Published: December 2021

La luciérnaga Photinus immigrans se conoce únicamente en la península ibérica, aunque probablemente es una especie originaria de Norteamérica. En esta nota presentamos el primer registro e ilustración de su larva. Ésta puede ser fácilmente identificada gracias a su patrón de coloración, formado en cada segmento por varias líneas longitudinales marrón claro o rojizas sobre fondo negro o marrón oscuro. Se han encontrado viviendo enterradas en capas superficiales del suelo, hasta 10–15 cm de profundidad. P. immigrans vive en simpatría con al menos otras tres especies de luciérnaga nativas de la península ibérica: Lampyris iberica, Nyctophila reichii and Lamprohiza mulsantii, aunque aparentemente no hay sintopía estricta al menos durante las fases larvarias. Las larvas de P. immigrans probablemente utilizan recursos tróficos parcialmente diferentes a los de las especies nativas, y su señalización luminosa es también muy diferente a aquellas de otras especies simpátricas, aunque es necesario un estudio en profundidad sobre competencia interespecífica y el posible efecto de esta especie exótica sobre las luciérnagas nativas.

How the initial retentive force of implant-supported overdentures can be affected with splinted and unsplinted attachments systems
Authors: Nejatidanesh Farahnaz , Savabi Omid , Savabi Ghazal , Razavi Mehdi 
Published: December 2021

Background:
The aim of this study was to evaluate the retention of implant-supported overdentures with different attachment systems.

Materials and Methods:
In this in vitro study edentulous model with 2 Straumann implant in symphyseal region was used to make an overdenture with different attachment systems. (Dolder bar with 1 and 3 metal clips, Hader bar with 1 and 3 plastic clips, ball on bar with 2 and 4 plastic caps, Locator, Rhein plastic caps and Eleptical matrix). Retention values were recorded by universal testing machine with a cross speed of 50.8 mm/min in vertical, posteroanterior, and lateral direction. Repeated measure ANOVA and Duncan tests were used for the data analysis (α =0.05).

Results:
There was a statistically significant difference between the retention values of studied attachments in different dislodgment directions (P < 0.05). The highest and lowest retention were recorded for 4 balls on bar (56.71 N) and Rhein pink caps (27.89 N) in the vertical direction. Three metal clips (61.43 N) and Rhein pink cap (24.77 had the highest and lowest retention force in the posteroanterior direction. In the lateral direction, 4 balls on bar (62.68 N) and 1 plastic clip (32.27 N) showed the highest and lowest retention, respectively.

Conclusion:
If the higher retention force has been considered for implant-supported overdenture attachment selection, the clinician can use splinted bar or ball on bar superstructure.

Published: December 2021

Background:
This study aimed to assess and compare the type of dental procedures performed under general anesthesia for healthy and disabled children.

Materials and Methods:
This descriptive, cross-sectional study evaluated 361 dental records of children who received dental treatments under general anesthesia in the operating room of Torabinejad Research Center during 2011–2013. Patients with mental or physical disability were categorized as disabled. The age and gender of patients, number of treated teeth, duration of general anesthesia, type of tooth, and type of dental treatment such as extraction, pulp therapy, placement of stainless steel crowns, composite restoration, preventive resin restoration (PRR), fissure sealant treatment, and fluoride therapy were separately recorded for the healthy group and patients with disability. Data were analyzed using one-way ANOVA, and independent sample t-test at P < 0.05 level of significance.

Results:
Of 361 patients, 263 patients were healthy and 102 patients had disability. Of all disabled children, 48% had physical and 52% had mental disability. Among patients with physical disability, allergy (40%), followed by cardiovascular diseases (26%) were the most common. Mental retardation (54%) followed by cerebral palsy (10%) were the most common mental disabilities. Number of extracted teeth was significantly higher in disabled children (P = 0.006). Furthermore, disabled children received significantly lower PRR (P = 0.015), fissure sealant treatment (P = 0.003), fluoride therapy (P = 0.002), and pulp therapy (P < 0.001) compared with healthy children.

Conclusion:
Tooth extraction has a higher frequency in disabled children; while, attempts are made to preserve the teeth as much as possible in healthy children.
Endovenous Laser Therapy in Varicose Veins-Recanalization Rate and Quality of Life
Authors: Tiwari Kritika , Kamerkar Dhanesh R , Shinde Bhushan 
Published: December 2021

Context:
In endovenous ablation under ultrasound guidance the saphenous vein is percutaneously accessed and the catheter is advanced cephalad toward the saphenofemoral junction. Tumescent anesthesia and thermal energy are used in concert to provide an effective means of eliminating great saphenous vein reflux.

Aims and Objectives:
Primary objective – (1) To study recanalization rate after light amplification stimulated by emission of radiation (LASER) in the varicose vein. Secondary Objectives are to Study – (1) Clinical effectiveness of LASER in varicose veins. (2) Quality of life (QoL).

Materials and Methods:
Single institute based prospective observational study of 81 patients undergoing LASER ablation for varicose veins was observed for 12 months post LASER ablation. Patients were assessed for residual varicosities, new varicosities, recurrence, complications, and QoL.

Results:
There was no recanalization of ablated veins at the end of 12 months. About 96.3% of patients remained free from developing new varicosities, whereas only 18.5% of patients had residual varicosities postprocedure at the initial follow-up which has been successfully treated with foam sclerotherapy. QoL postprocedure improved significantly with 69 patients (85.2%) had excellent QoL after 12 months postprocedure.

Conclusion:
(1) Least residual varicosities postprocedure treated by foam sclerotherapy. (2) Development of new varicosities occurs late in follow-up. (3) Zero recurrence rate of ablated veins through LASER. (4) Postopearative complication of pain and paraesthesia are minimal due to adequate tumescent anesthesia. (5) Dreaded complication of deep venous thrombosis is not recorded in any of the cases because of early ambulation. (6) There is a significant improvement in QoL of patients from the start to the end of the study.
Idiopathic Large-Vessel Vasculitis Presenting as Acute Abdomen and Mesenteric Ischemia
Authors: Sekar Natarajan , Ponnuswamy Iyappan 
Published: December 2021

Objective:
The term “large-vessel vasculitis” encompasses the spectrum of primary vasculitis that causes chronic granulomatous inflammation predominantly of the aorta and its major branches. The two major categories of large-vessel (LV) vasculitis are giant cell arteritis and Takayasu arteritis. LV vasculitis of unknown etiology presenting as mesenteric ischemia is presented here.

Materials and Methods:
This is a single-center retrospective analysis of 17 patients who presented with mesenteric ischemia over a period of 7 years. Their age ranged from 18 to 69 years. There were five females and the rest were male. The presenting symptoms were abdominal pain, nausea, malaise, and low-grade fever. Peripheral pulses were normal. Computed tomography (CT) aortogram showed typical wall edema and inflammatory tissue encasing the superior mesenteric artery, celiac artery, and the adjacent aorta in all the patients. Thrombosis and localized dissection in the superior mesenteric and celiac arteries was seen in some. Erythrocyte sedimentation rate and C-reactive protein were elevated, but other vasculitis markers were normal.

Results:
All of them were treated with glucocorticoids with immediate relief from the symptoms. Anticoagulation was given for those with thrombus, stenosis, and dissection. None had any intervention. At 1-year follow-up, there was no recurrence, and all were asymptomatic.

Conclusion:
Idiopathic LV vasculitis can present as mesenteric ischemia and acute abdomen. CT aortogram typically shows inflammatory tissue around the visceral artery and the aorta. The etiology is still uncertain. However, this condition has many similarities with LV giant cell arteritis (GCA-LV). Hence, all investigations should be done to rule out GCA. They respond very well to glucocorticoids. Correct diagnosis can avoid an unnecessary surgery. Long-term follow-up is required in order not to miss any late complications This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.
