Cystic fibrosis (CF) is a progressive, genetic disease posing reproductive health concerns to affected women, such as high-risk pregnancies and medication interactions leading to contraceptive failure. Reproductive health counseling in this population is of the utmost importance, but barriers to providing it include lack of time, knowledge, and provider discomfort. We sought to evaluate reproductive health counseling and contraceptive use in female adolescent CF patients.

An Institutional Review Board approved retrospective chart review was performed between March 2008 and March 2018. Females 10-21 years old with the diagnosis of CF were reviewed. Descriptive statistics were used.

Thirty-three patients met inclusion criteria 16 non-sexually active and 17 sexually active. Thirteen patients were counseled about pregnancy risks. All sexually active patients used contraception, with the most common being condoms and combined oral contraceptive pills. Six pregnancies occurred, resulting in five live births and one termination.

Less than half of patients were counseled about pregnancy and contraception, and most patients chose high failure methods. Female adolescents with CF should be routinely screened for sexual activity, offered long-acting reversible contraception, and counseled on the effects of CF on pregnancy.

In addition to the development of an effective vaccine, it is imperative to understand how SARS-CoV-2 hijacks host cellular machineries on a system-wide scale so that potential host-directed therapies can be developed. In situ proteome-wide abundance and thermal stability measurements using thermal proteome profiling (TPP) can inform on global changes in protein activity. Here we adapted TPP to high biosafety conditions amenable to SARS-CoV-2 handling. We discovered pronounced temporal alterations in host protein thermostability during infection, which converged on cellular processes including cell cycle, microtubule and RNA splicing regulation. Pharmacological inhibition of host proteins displaying altered thermal stability or abundance during infection suppressed SARS-CoV-2 replication. Overall, this work serves as a framework for expanding TPP workflows to globally important human pathogens that require high biosafety containment and provides deeper resolution into the molecular changes induced by SARS-CoV-2 infection.
Gait impairment is common in neurodegenerative disorders. Specifically, gait variability-the stride-to-stride fluctuations in distance and time-has been associated with neurodegeneration and cognitive impairment. However, quantitative comparisons of gait impairments across the cognitive spectrum of dementias have not been systematically investigated.

Older adults (N=500) with subjective cognitive impairment, Parkinson disease (PD), mild cognitive impairment (MCI), PD-MCI, Alzheimer's disease (AD), PD-dementia, Lewy body dementia, and frontotemporal dementia, as well cognitive normal controls, who were assessed for their gait and cognitive performance.

Factor analyses grouped 11 quantitative gait parameters and identified four independent gait domains rhythm, pace, variability, and postural control, for group comparisons and classification analysis. Among these domains, only high gait variability was associated with lower cognitive performance and accurately discriminated AD from other neurodegenerative and cognitive conditions.

Our findings indicate that high gait variability is a marker of cognitive-cortical dysfunction, which can help to identify Alzheimer's disease dementia.

These reactions involved internal transfer of the sulfinyl oxygen atom to form a thiooxime intermediate tethered to an α-oxo gold carbene moiety. Subsequent insertion of the carbene into the N-S bond resulted in ring construction.Laparoscopic wedge resection (LWR) for intraluminal gastrointestinal stromal tumor (GIST) leads to excessive resection of normal gastric wall. We report a case of GIST around the cardia successfully treated with full-thickness partial resection using a hybrid approach of laparoscopic surgery and single-incision intragastric surgery (SIIGS). A 69-year-old woman had a 5 cm intraluminal GIST at the posterior wall around the cardia. Submucosal injection of glycerin and indigo carmine was performed with transoral endoscopy. Circumferential seromuscular incision followed by placement of seromuscular sutures to invert the lesion into the stomach was performed under laparoscopy. By SIIGS, resection of the inverted mucosa and retrieval of the tumor were completed. A hybrid approach consisting of laparoscopic wall-inversion surgery and SIIGS was useful for intraluminal GIST and may expand the indications for laparoscopic wall-inversion surgery by removing size limitations.
To describe the surgical repair of traumatic complete spectaculectomy and keratomalacia in a snake.

A 10.5-year-old, female, Boelen's python (Simalia boeleni) was presented with iatrogenic, near-complete spectaculectomy associated with bacterial keratitis, keratomalacia, and hypopyon.

Corneal samples for cytological evaluation and bacterial culture were collected. Following medical stabilization of the bacterial keratitis, a double-layered dry amniotic membrane graft was placed. The first amniotic membrane layer was placed over the cornea with the edges tucked under the peripheral remnants of the spectacle and secured in place with fibrin glue. The second amniotic membrane layer was placed over the entirety of the spectacle remnant and secured in place with a combination of fibrin glue and sutures. Topical and systemic antimicrobials, topical ophthalmic lubricants, and systemic non-steroidal anti-inflammatory therapy were administered postoperatively.

Heterophilic keratitis was identified by cytology and Enterobacter cloacae, Pseudomonas aeruginosa, and Staphylococcus sciuri were cultured from the corneal samples. The amniotic membrane grafts remained in place for several weeks. At 4months postoperatively, the spectacle was completely regenerated, the subspectacular space restored, and the cornea was transparent. Spectacular vascularization and fibrosis then slowly cleared over the following 6months.

Amniotic membrane grafting with fibrin glue is a relatively simple and effective surgical method to reconstruct extensive defects in the reptilian spectacle and to assist in the management of bacterial keratitis associated with spectacle avulsion.

Gene interaction not only applies to normal human traits but to the diseased samples as well. Thus, an analysis of gene interaction could help us to differentiate between the normal and the diseased samples or between the two/more phases any diseased samples. At the first stage of this work we have used restricted Boltzmann machine model to find such significant interactions present in normal and/or cancer samples of every gene pairs of 20 genes of colorectal cancer data set (GDS4382) along with the weight/degree of those interactions. read more Later on, we are looking for those interactions present in adenoma and/or carcinoma samples of the same 20 genes of colorectal cancer data set (GDS1777). The weight/degree of those interactions represents how strong/weak an interaction is. At the end we will create a gene regulatory network with the help of those interactions, where the regulatory genes are identified by using Naïve Bayes Classifier. Experimental results are validated biologically by comparing the interactions with NCBI databases.Various innovative robotic systems have been developed to improve surgery precision. The Senhance Surgical System (SSS) is a digital laparoscopic system offering eye tracking and haptic feedback. Several reports have described application of the SSS to general surgeries, including cholecystectomy and colectomy. However, use of the SSS for gastric tumor has not been reported. We experienced a case of laparoscopic local gastrectomy (LLG) for gastrointestinal stromal tumor (GIST) with the SSS. A 74-year-old man diagnosed with GIST underwent LLG with the SSS. Operation, docking, and console times were 117, 11, and 59 minutes, respectively. No perioperative complications were encountered. This study is the first to report LLG for GIST with the SSS. LLG with the SSS was safe and feasible. The SSS can use reusable forceps and contribute to reducing medical costs. The development of instruments is also progressing, and various kinds of surgery are likely to be indicated.The class C G protein-coupled sweet taste receptor (STR) is responsible for the perception of sweet-tasting molecules. Considered an obligate heterodimer, it consists of taste 1 receptor 2 and taste 1 receptor 3 subunits. Interest in the STR has steadily grown, especially since its discovery in extraoral tissues hints at a metabolic role for the receptor. It is now known that many pharmacologically exploitable binding sites exist across the extracellular and transmembrane regions of both subunits of the STR, indicative of its potential amenability to pharmacotherapeutic modulation. In this review, we briefly describe the structural characteristics and functional relevance of the STR. Then, from a molecular pharmacology perspective, we dissect the research surrounding the regulation of STR surface expression and signal transduction, in both oral and extraoral tissues, and discuss the potential for the exploitation of biased agonists for the STR. We find that despite 20 years of research into the STR, the target remains frustratingly enigmatic. Not only are the mechanisms controlling and regulating the surface expression of the STR unclear, but also research into the full repertoire of signaling partners of the STR is at present inconclusive. Critically, the influence of receptor polymorphisms (including those associated with sugar consumption) on the molecular pharmacology of the receptor remains hitherto unexplored. Finally, we provide recommendations on the reporting of reference sequence identification numbers to avoid incorrect attribution of wild-type to these biologically significant polymorphisms, which we argue may have led to some of the inconsistencies in the field.
