[This retracts the article DOI 10.2147/OTT.S225360.].The COVID-19 pandemic has strained health care systems around the world. Pharmacists have made substantial contributions to the health care operations during the COVID-19 response. The Pharmacy Department at Qatar Primary Health Care Corporation (PHCC) acted proactively to ensure that all patients received their medications and their refilled prescriptions in time and without any disruption. The Medication Home Delivery Service was introduced and implemented for all Qatar residents to prevent unnecessary visits to health centers, minimize the spread of COVID-19 to vulnerable populations, especially those with multiple comorbidities, and protect health care workers from exposure to the virus. Moreover, several other precautionary measures were taken by the PHCC to ensure uninterrupted access to health care, including moving to a virtual health care delivery model. As of September 2020, the service had served around 64,213 patients since its launch in March 2020. In total, 70,357 medications were delivered and 69,092 (98.2%) medication packages were delivered successfully to patients, with an average of 450.8 medication packages delivered per month. Despite various challenges, the PHCC is considering continuing the Medication Home Delivery Service in the long term to continue with a more effective and efficient service for patients during the coming months and years.
The development of beta-blocker (BB) medications is considered one of the most critical milestones of drug research. Several trials showed possible anti-anxiety effects of BBs. Our primary goal is to investigate the prevalence of anxiety disorder and the use of BBs as anxiolytic without medical prescription among medical and pharmacological students in Saudi Arabia.

A cross-sectional study was conducted at multiple universities in Saudi Arabia. Students were given a questionnaire containing 44 questions that included demographic data, school location, BB usage behavior, GPA status before and after using BBs, and a GAD-7 anxiety screening questionnaire.

A total of 3326 mainly female senior students participated in the study with a mean age of 21.9±1.7 years. According to the GAD-7 score, half of the sampled students did not meet criteria indicative of anxiety disorder, and one-third were considered to have mild anxiety with a significant positive correlation between the BB usage and the GAD-7 score. A total of 6.4% of the sample reported usage of BBs. Therapeutics and Internal Medicine were the most common subjects for which BBs were used. When compared to pharmacy students, medical students were more likely to be male, smokers, diagnosed with psychiatric illness, having a higher mean GAD-7 score, report BB usage, and correctly identified common and serious BB side effects.

The inappropriate use of BB drugs without medical advice might have short- and long-term effects, and those may be more vulnerable to have psychological issues in the future. Our findings shed light on the need to identify students who are taking BBs as being at high risk of underlying anxiety disorders.

Translation of nanomedical developments into clinical application is receiving an increasing interest. However, its use for oral squamous cell carcinoma (OSCC) diagnosis remains limited. We present an advanced nanophotonic method for oral cancer detection, based on diffusion reflection (DR) measurements of gold-nanorods bio-conjugated to anti-epidermal growth factor receptor (C-GNRs) specifically attached to OSCC cells.

To investigate in a rat model of oral carcinogenesis the targeting potential of C-GNRs to OSCC by using the DR optical method.

OSCC was induced by the carcinogen 4-nitroquinoline-N-oxide (4NQO). C-GNRs were introduced locally and systemically and DR measurements were recorded from the surface of the rat tongue following illumination with red laser beam. Rats were divided into experimental and control groups. The results were compared with the histologic diagnosis.

A total of 75 Wistar-derived rats were enrolled in the study. Local application did not reveal any statistical results. DR of nanophotonics for oral cancer identification, and provides support for the use of C-GNRs as a selective drug delivery.
In this paper, we have designed and formulated, a novel synthesis of doxorubicin (DOX) loaded bimetallic gold nanorods in which gold salt (HAuCl
) is chelated with anthracycline (DOX), diacid polyethylene-glycol (PEG-COOH) and gadolinium salt (GdCl
* 6 H
O) to form DOX IN-Gd-AuNRs compared with DOX ON-Gd-AuNRs in which the drug was grafted onto the bimetallic pegylated nanoparticle surface by electrostatic adsorption.

The physical and chemical evaluation was performed by spectroscopic analytical techniques (Raman spectroscopy, UV-Visible and transmission electron microscopy (TEM)). Magnetic features at 7T were also measured. Photothermal abilities were assessed. Cytotoxicity studies on MIA PaCa-2, human pancreatic carcinoma and TIB-75 hepatocytes cell lines were carried out to evaluate their biocompatibility and showed a 320 fold higher efficiency for DOX after encapsulation.

Exhaustive physicochemical characterization studies were conducted showing a mid size of 20 to 40 nm diameters obtained with metallic theranostic nanomaterial system represents a veritable promise as a therapeutic entity in the field of medicinal applications.
In this paper, we have developed a novel theranostic nanoparticle composed of gadolinium complexes to gold ions, with a PEG biopolymer matrix conjugated with antitumoral doxorubicin, providing multifunctional therapeutic features. Particularly, these nano conjugates enhanced the cytotoxicity toward tumoral MIAPaCa-2 cells by a factor of 320 compared to doxorubicin alone. Moreover, MRI T1 features at 7T enables interesting positive contrast for bioimaging and their adapted size for potential passive targeting to tumors by Enhanced Permeability Retention. Given these encouraging antitumoral and imaging properties, this bimetallic theranostic nanomaterial system represents a veritable promise as a therapeutic entity in the field of medicinal applications.
It is well known that smoking is harmful to health; however, it can also ameliorate anxiety. To date, it is unclear whether any nanoparticles found in cigarette mainstream smoke (CS) contribute to this effect.

The aim of this study was to assess the particle composition of CS to identify novel anti-anxiety components.

Carbon dots (CDs) from CS (CS-CDs) were characterised using high-resolution transmission electron microscopy, Fourier-transform infrared, ultraviolet, fluorescence, X-ray photoelectron spectroscopy, X-ray diffraction and high-performance liquid chromatography. The anti-anxiety effects of CS-CDs in mouse models were evaluated and confirmed with the elevated plus maze and open-field tests.

The quantum yield of CS-CDs was 13.74%, with a composition of C, O, and N. Silmitasertib order In addition, the surface groups contained O-H, C-H, C=O, C-N, N-H, C-O-C, and COO- bonds. Acute toxicity testing revealed that CS-CDs had low in vitro and in vivo toxicity within a certain concentration range. The results of the elevated plus maze and open-field tests showed that CS-CDs had a significant anti-anxiety effect and a certain sedative effect in mice. The mechanism of these effects may be related to the decrease in glutamate levels and promotion of norepinephrine production in the mouse brain, and the decrease in dopamine in mouse serum due to CS-CDs.

CS-CDs may have anti-anxiety and certain sedative effects. This study provides a new perspective for a more comprehensive understanding of the components, properties, and functions of CS. Furthermore, it offers a novel target for the development of smoking cessation treatments, such as nicotine replacement therapy.

Postoperative delirium (POD) is a serious complication of cardiac surgery. It is an acute neuropsychiatric syndrome. The aim of this study was to analyze the CARDEL Index, composed of advancing age, preoperative glycated hemoglobin and the platelet-to-WBC ratio (PWR) previously described and calculated, using a different patient database, to assess its usefulness as a marker for predicting postoperative delirium after coronary artery by-pass grafting (CABG).

A retrospective analysis of 1098 patients who underwent, isolated CABG procedures between 2017 and 2019 was performed.

Within the study group, 164/1098 (14.93%) patients were diagnosed with delirium. Preoperative inflammatory parameters were elevated in patients with delirium White Blood Cell count (p=0.003), Neutrophil count (p=0.016) and C-reactive protein (p<0.001). A decrease in preoperative PWR was shown in patients with delirium (p=0.008). Delirious patients spent more time mechanically ventilated (p<0.001) and had longer hospitalization times (p=0.002). Mortality at 1 year was significantly higher in patients with POD (p<0.001). The CARDEL Index in this study group for POD detection has the largest area under the curve (AUC) of 0.664 (p<0.001) and a cut-off value of 8.08.

CARDEL Index may be treated as a potentially valuable tool for delirium prediction in patients after CABG.

Controversy remains around intramedullary fixation of intertrochanteric fractures in elderly patients when considering hidden blood loss (HBL). However, whether treating the fractures with intramedullary fixation causes a large amount of HBL is not known.

In this retrospective cohort study, 1,017 consecutive patients aged ≥65 years with acute intertrochanteric fractures were included and assigned to three groups (non-operative group, delayed surgery group, and acute surgery group) between July 2013 and January 2018. The data of patients' demographics, injury-related data, operation-related data, comorbidities, perioperative hemoglobin values, transfusion data and serial of HBL calculated during hospitalization were collected and compared among three groups. All independent variables were further analyzed by multiple linear regression to evaluate the influential factors of HBL. A long-term follow-up was conducted and survival analysis was performed for all individuals.

Our results showed that fixation bymain component of total blood loss and it is more likely to result from the initial trauma rather than the surgery. Intertrochanteric fracture treated by intramedullary fixation does not cause a large amount of HBL.Severe acute respiratory syndrome coronavirus clade 2 (SARS-CoV-2) is an emerging pathogen, which is similar to previous SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV) occurrences. However, we only get few understandings about the pathogenesis of SARS-CoV-2, which need to further be studied. The discovery of an agent that has a treatment efficacy against SARS-CoV-2 is very urgent. In this review, we briefly discuss the virology of this pathogen and focus on the available understanding of the pathogenesis and treatments of this pathogen including the uses of nucleoside analogues, protease inhibitors, interferons, and other small-molecule drugs, on the basis previous comprehensions of SARS and MERS. These reviewed concepts may be beneficial in providing new insights and potential treatments for COVID-19.
