Duration of biophysical profile in periviable and very preterm low-risk pregnancies.

Background: In recent years, perinatal viability has shifted from 24 to 22 weeks of gestation at many institutions after improvements in survival in neonates delivered at the limit of viability. Monitoring these fetuses is essential because antenatal interventions with resuscitation efforts are available for patients at risk of delivery at the limit of viability. However, fetal monitoring using biophysical profiles has not been extensively studied in very preterm pregnancies, particularly in the periviable period (20 weeks 0 days to 23 weeks 6 days).

Spatial congruency or discrepancy? Exploring the spatiotemporal dynamics of built-up expansion patterns and flood risk.

Most coastal cities have been experiencing unprecedented urbanization-induced flood risk, climatic events, and haphazard anthropogenic activities, jeopardizing residents' lives and building environments. Despite mounting flood-related studies, analyzing the correlation between the spatiotemporal dynamics of Built-up Expansion patterns (BE) and flood risk remains unknown and holds divergent perspectives. In this context, the coastal city of Alexandria, Egypt, characterized by multiple urban patterns and experiencing heavy rainfall annually, was selected as a testbed.

EuCd_{2}As_{2}: A Magnetic Semiconductor.

EuCd_{2}As_{2} is now widely accepted as a topological semimetal in which a Weyl phase is induced by an external magnetic field. We challenge this view through firm experimental evidence using a combination of electronic transport, optical spectroscopy, and excited-state photoemission spectroscopy. We show that the EuCd_{2}As_{2} is in fact a semiconductor with a gap of 0.

Estimating the nonideality of eutectic systems containing thermally unstable substances.

Eutectic systems design requires an in-depth understanding of their solid-liquid equilibria (SLE). Modeling SLE in eutectic systems has as prerequisites, the melting properties and activity coefficients of components in the liquid phase. Thus, due to the unavailable melting properties of thermally unstable substances, it is impossible to estimate their activity coefficients from experimental SLE data and model the SLE phase diagram of their eutectic systems.

Outcomes in Pregnant Adolescent Patients Infected With SARS-CoV-2.

Background: Pregnant patients with coronavirus disease 2019 (COVID-19) are at risk for adverse pregnancy outcomes. Although clinical outcomes for pregnant adults have been reported, the impact of COVID-19 on adolescents is lacking. We sought to evaluate obstetric outcomes of pregnant adolescents infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and compare them with uninfected adolescent controls.

Design of Deep Eutectic Systems: Plastic Crystalline Materials as Constituents.

Deep eutectic solvents (DESs) are a class of green and tunable solvents that can be formed by mixing constituents having very low melting entropies and enthalpies. As types of materials that meet these requirements, plastic crystalline materials (PCs) with highly symmetrical and disordered crystal structures can be envisaged as promising DES constituents. In this work, three PCs, namely, neopentyl alcohol, pivalic acid, and neopentyl glycol, were studied as DES constituents.

SNAPSHOT USA 2019: a coordinated national camera trap survey of the United States.

With the accelerating pace of global change, it is imperative that we obtain rapid inventories of the status and distribution of wildlife for ecological inferences and conservation planning. To address this challenge, we launched the SNAPSHOT USA project, a collaborative survey of terrestrial wildlife populations using camera traps across the United States. For our first annual survey, we compiled data across all 50 states during a 14-week period (17 August-24 November of 2019).

Pharmacological treatment in pregnant women with moderate symptoms of coronavirus disease 2019 (COVID-19) pneumonia.

Objective: Pregnant women with moderate symptoms of COVID-19 are at risk for progressing to severe or critical illness. While there are limited data on the management of severe COVID-19 during pregnancy, information on pharmacological treatments of moderate COVID-19 is lacking. We report clinical outcomes of pregnant women hospitalized due to moderate COVID-19 illness treated with a 5-day course of remdesivir, antibiotics, and/or glucocorticoids.

A study on the type of lesions achieved by three electrosurgical methods and their way of healing.

The technical progress in the medical sector in the past decades has continuously driven the development of electrosurgical techniques. The controversies surrounding the superiority of a certain technique relative to another - electrocautery, laser and radiofrequency - have determined us to carry out a histopathological design with the aim of comparing the healing sort of the shallow wounds generated by the three types of electrosurgical devices. The experimental study has investigated the healing process inflicted by the electrosurgical devices mentioned beforehand on 12 Wistar albino rats.

Evaporation-driven growth of large crystallized salt structures in a porous medium.

Subflorescence refers to crystallized salt structures that form inside a porous medium. We report a drying experiment revealing major development of subflorescence in the dry region of the porous medium away from the liquid zone. Using a combination of image analyses and numerical computations, we show that the growth is directly correlated to the evaporation flux distribution along the boundary of the growing salt structure.

Insulin Degludec, The New Generation Basal Insulin or Just another Basal Insulin?

The advances in recombinant DNA technology have led to an improvement in the properties of currently available long-acting insulin analogs. Insulin degludec, a new generation ultra-long-acting basal insulin, currently in phase 3 clinical trials, has a promising future in clinical use. When compared to its rival basal insulin analogs, a longer duration of action and lower incidence of hypoglycemic events in both type 1 and type 2 diabetic patients has been demonstrated.

Impaired muscle AMPK activation in the metabolic syndrome may attenuate improved insulin action after exercise training.

Context: Strength training induces muscle remodeling and may improve insulin responsiveness.

Objective: This study will quantify the impact of resistance training on insulin sensitivity in subjects with the metabolic syndrome and correlate this with activation of intramuscular pathways mediating mitochondrial biogenesis and muscle fiber hypertrophy.

Design: Ten subjects with the metabolic syndrome (MS) and nine sedentary controls underwent 8 wk of supervised resistance exercise training with pre- and posttraining anthropometric and muscle biochemical assessments.

Patient-physician boundaries in palliative care training: a case study and discussion.

Abstract The subject of patient-physician boundaries has been most extensively explored in the psychiatric literature, but to date, little has been published about this concept within the realm of palliative care. Some palliative care physicians may be particularly susceptible to boundary crossings due to the intensity and intimacy of the bonds that form with patients at the end-of-life. We illustrate the concept of boundary crossings and violations in palliative care using the case of a palliative care trainee who experiences difficulties in maintaining boundaries with a dying patient.

Phase II study of gemcitabine combined with radiation therapy in patients with localized, unresectable pancreatic cancer.

Background And Objectives: Gemcitabine is an active agent in pancreatic cancer, with known radiosensitizing properties. Therefore, a phase II study was conducted to evaluate the efficacy of gemcitabine combined with radiation therapy in patients with localized unresectable adenocarcinoma of the pancreas.

Methods: Weekly gemcitabine at a dose of 1,000 mg/m(2) for 7 weeks was given as an induction phase.

Relationship of dietary intake to DDE residues in breast milk of nursing mothers in Beirut.

Milk samples were collected from 32 nursing mothers living in the Beirut area, Lebanon. Dietary intakes of participating mothers were obtained from data of their diet histories, 24 h dietary recalls and food frequency questionnaires. Milk samples were screened for the presence of organochlorine pesticide residues and DDE levels were estimated using gas chromatographic techniques.

Clinical characteristics of second primary tumors following breast cancer.

In the Multiple Primary Tumor Registry of the Northern Israel Cancer Center we found 247 patients with breast cancer who developed a second primary tumor. The major sites of the second tumor were mainly the other breast (42%), colon (14%), ovary (8%), and endometrium (7%). Only 24% of the second tumors were diagnosed in asymptomatic patients on a routine follow-up examination; 60% of these patients had contralateral breast cancer and 8% had colon cancer.

Clinical characteristics of patients with a second primary tumor in the endometrium or ovary.

The clinical characteristics of patients with second primary tumors in the ovary and endometrium were compared to those with single primary tumors treated at our Center during the same period of time. Despite the fact that the patients were under medical surveillance for the first primary tumor, most second tumors were diagnosed following patient symptoms and complaints, and not at a routine follow-up appointment. Patients with a second primary endometrial cancer had a more advanced stage of disease at diagnosis as compared to those with single endometrial cancer.

Clinical, demographic, and follow-up characteristics of patients with two primary metachronous tumors, one of them being in the colon.

The clinical characteristics of 152 patients diagnosed with two primary metachronous tumors--one or both of them in the colon--were studied. Nineteen patients had both primary tumors in the colon (Group I), 59 had the first primary tumor in the colon and the second tumor elsewhere (Group II), and 74 had the second primary tumor in the colon and the first primary tumor elsewhere (Group III). The group in which the second primary tumor was in the colon included significantly more female patients than did the other two groups, with a younger median age at diagnosis of first tumor.

Diflunisal and ibuprofen: effects on gastric and duodenal mucosa in patients with osteoarthritis.

Patients with osteoarthritis make up the largest group of users of nonsteroidal anti-inflammatory drugs (NSAIDs), but the effects of these agents on the gastrointestinal mucosa of such patients have not been well studied. This article describes a short-term comparison of two widely used NSAIDs, diflunisal and ibuprofen, in patients requiring these medications for their osteoarthritis. Efficacy, tolerability, and endoscopically documented effects of these drugs on the gastric and duodenal mucosa were assessed.

Crohn's disease complicated by idiopathic central serous chorioretinopathy with bullous retinal detachment.

A case of idiopathic central serous chorioretinopathy with bullous retinal detachment occurring in a patient with Crohn's disease is described. This rare eye condition (36 reported cases in the world's literature) has previously been seen in association with ulcerative colitis, and its occurrence in a patient with Crohn's disease suggests that it may represent another ophthalmologic complication of inflammatory bowel disease.

The significance of gastric bile reflux seen at endoscopy.

We evaluated the significance of bile seen in the stomach at the time of endoscopy. Twenty-three percent of 110 consecutive patients undergoing elective panendoscopy were found to have bile in their stomachs. Gastric biopsies were obtained from these patients.

Radionuclide esophageal emptying and manometric studies in diabetes mellitus.

Esophageal function was prospectively studied in 50 consecutive insulin-requiring diabetes mellitus patients. The patients were stratified in three groups: A) 18 without peripheral neuropathy (PN); B) 20 with PN but no autonomic neuropathy; C) 12 with PN and autonomic neuropathy. Twelve patients (four B, eight C) had gastrointestinal symptoms including six with dysphagia.
