67-0.89) and 0.73 (95% CI, 0.59-0.87) in the training and validation cohorts, respectively. Radiomics nomogram, incorporating the radiomics signature with the conventional clinical variables, also performed well in the two cohorts (training cohort AUC, 0.84; validation cohort AUC, 0.82). Moreover, we found that the high-risk patients determined by our radiomics nomogram could benefit from postoperative adjuvant chemotherapy, while the low-risk and total patient groups could not.

Our novel radiomics nomogram is a promising and favorable prognostic biomarker for preoperatively predicting survival outcomes and may aid in clinical decision-making in BC patients with residual tumors after NAC.

Head and neck squamous cell carcinoma (HNSCC) is a leading cancer with high morbidity and mortality worldwide. The aim is to identify genes with clinical significance by integrated bioinformatics analysis and investigate their function in HNSCC.

We downloaded and analyzed two gene expression datasets of GSE6631 and GSE107591 to screen differentially expressed genes (DEGs) in HNSCC. Common DEGs were functionally analyzed by Gene ontology and KEGG pathway enrichment analysis. Protein-protein interaction (PPI) network was constructed with STRING database and Cytoscape.

Paclitaxel liposome (Lipusu) is the first commercialized liposomal formulation of paclitaxel. There has been little data collected on the pharmacokinetics (PK) of paclitaxel liposome, especially in relation to patient use. This study aimed to build a population pharmacokinetic (PopPK) model and further explore the exposure-safety relationship for paclitaxel liposome in patients with non-small cell lung cancer (NSCLC).

Data from 45 patients with a total of 349 plasma concentrations were analyzed. The PopPK model was built using the non-linear mixed effect modeling technique.

The PK of paclitaxel liposome were well described by a three-compartment model with first-order elimination. For a dose of 175 mg m

, the estimated clearance of total plasma paclitaxel was 21.55 L h

. Age, sex, body weight, total bilirubin, albumin, serum creatinine, and creatinine clearance did not influence the paclitaxel PK. Exposure to paclitaxel had no significant change in the presence of the traditional Chinese medicine, aidi injection. The exploratory exposure-safety relationship was well described by a generalized linear regression model. Higher probabilities of grade >1 neutropenia were observed in patients with higher exposure to paclitaxel.

This PopPK model adequately described the PK of paclitaxel liposome in patients with NSCLC. Predicted exposure of paclitaxel did not change in the presence of the traditional Chinese medicine, aidi injection. The exposure-safety analysis suggested that a higher risk of neutropenia was correlated with higher exposure to paclitaxel.

The first case was identified in December 2019, in Wuhan, China. It is an infectious disease and has led to the ongoing global pandemic. This pandemic has also started in Assam, with its first case reported on 31 March, 2020. A prospective study was conducted on 2000 laboratory confirmed coronavirus cases. Proper history were taken and clinical examinations were performed. They were also advised to do the necessary blood investigations, electrocardiogram and chest X- rays. Olfactory functions were assessed using substances like scented soap, mint toothpaste, vicks vaporub, etc. Gustatory functions were also assessed. In our study, we found that 83% (1650) patients presented with otorhinolaryngological or ENT (Ear, nose, throat) manifestations and 17% (350) did not have any otorhinolaryngological manifestations. The most common ENT symptoms with which the patients presented were sore throat (80%) and headache (76%). The other ENT symptoms were hyposmia (44%), dysgeusia (32%) and nasal congestion (28%). The most common non-ENT symptoms were fever (92%) and cough (85%). The other non-ENT symptoms with which the patient presented were malaise, generalized bodyache and abdominal symptoms (like diarrhea). This prospective study gives a view of the incidence of otorhinolaryngological manifestations in COVID 19 patients. But, no significant co-relation was seen between presence of ENT symptoms and the severity of the disease. However, further studies are required to know the pathogenesis of causing ENT symptoms properly and also for definitive treatment of these symptoms.The pandemic of COVID 19 has taken a massive toll of lives since its outbreak. Throughout the world with a large number of people being affected by covid 19, the need for the ventilators has risen. However, there is disproportionate ratio of demand versus supply of ventilators due to the menace caused by Covid 19 which has become unmanageable. This paper describes the design of the low cost portable mechanical bag valve mask compressor which could serve as a preliminary ventilator for the patients needing ventilator support in COVID 19. This prototype ventilator delivers breaths by compressing a conventional bag-valve mask (BVM) with a motor, eliminating the need for a human operator for the BVM. It is driven by a wind shield wiper electric motor powered by a 12 V battery. Additionally it can be used to deliver oxygen through either Laryngeal mask or compact face masks or nasopharyngeal airways where intubation is awaited in early breathlessness. Future additions for our prototype ventilator will include a controllable inspiration to expiration time ratio, a pressure relief valve, PEEP capabilities and an LCD screen. With a prototyping cost of only $150, the concept of BVM compressor is a low-cost, low-power portable ventilator technology that will provide essential ventilator features at a fraction of the cost of existing technology.

To report the effectiveness of intravitreal implantation of dexamethasone implant (Ozurdex) after phacoemulsification and intraocular lens implantation in refractory uveitis patients.

This single-center retrospective study conducted for refractory pan-uveitis patients who underwent cataract surgery combined with intravitreal Ozurdex implantation. The main outcome measurements were best-corrected visual acuity (BCVA), central retinal thickness (CRT), grade of anterior chamber cell (AAC), intraocular pressure (IOP), and systemic/ocular adverse events.

Ten eyes of 7 patients were included. BCVA showed significant improvement at 1mo (

=0.004), 3mo (

=0.0004), and 6mo (

=0.001) post operation. There were no statistically significant differences in the postoperative CRT among follow-up groups (

>0.05). No significant differences were observed in the baseline IOP when compared to 1, 3, and 6mo (all

>0.05) post operation. One patient developed a transient elevated IOP post injection. Two eyes (20%) is considered a safe and effective approach to control postoperative inflammation in cataract surgery for patients with refractory uveitis in our study. After the disappearance of Ozurdex's anti-inflammatory effects over time, in most cases the recurrent inflammation can be controlled by topical steroids.

To assess the effectiveness, safety, and cost-effectiveness of the Argus II in treatment of the retinitis pigmentosa (RP) patients.

The ProQuest, Web of Science, EMBASE, MEDLINE (

PubMed) were searched using combinations of the keywords of Argus, safety, effectiveness, bionic eye, retinal prosthesis, and RP through March 2018. The retrieved records were screened and then assessed for eligibility.

Totally 926 records were retrieved from the searched databases and finally 12 studies included. The RP patients showed improvements in visual function after receiving the prosthesis, compared to the time before the prosthesis or the time it was off. This was measured by square localization, direction of motion, and grating visual acuity tests. No major adverse effect was reported for the Argus II prosthesis itself and/or the surgery to implement it, but the most frequently reported items were hypotony, and conjunctival dehiscence. The incremental cost-effectiveness ratio (ICER) was calculated to be €14603 per quality-adjusted life year (QALY) in UK and $207 616 per QALY in Canada.

The available evidence shows that the Argus II prosthesis in RP patients is effective in improvement of their visual function. Some minor adverse effects are reported for the prosthesis. The cost-effectiveness studies show that the technology is cost-effective only at high levels of willingness-to-pay.

A periodical review of guidelines is required to assure the optimal emergency management. We reviewed the literature with emphasis on current German guidelines, primarily MEDLINE. If the crucial first-line measure, the injury prevention has failed and an eye burn has been sustained, the immediate and copious rinsing of the eye is the pivotal emergency treatment modality. Whereas the immediacy and sufficiency of the emergency rinsing are largely unanimous, there is an ongoing debate about the benefits and risks of specific rinsing solutions, and regular updates on guidelines and recommendations for the emergency treatment are warranted. The easiest and readily available rinsing solution is tap water, which fulfils the crucial criteria conveniently in most industrialized countries purity, sterility, and neutral pH. Other rinsing solutions are proposing higher osmolality to stabilize the physiological pH, because of their superior buffering capacity.
