Depression, anxiety and stress among healthcare workers in the context of the COVID-19 pandemic: a cross-sectional study in a tertiary hospital in Northern Vietnam.

Introduction: The outbreak of coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) had significant effects on the mental well-being in general, particularly for healthcare professionals. This study examined the prevalence of depression, anxiety, and stress, and identified the associated risk factors amongst healthcare workers during the COVID-19 outbreak in a tertiary hospital located in Vietnam.

Methods: We conducted a cross-sectional study at a tertiary-level hospital, where the Depression Anxiety and Stress Scale 21 (DASS-21) web-based questionnaire was employed.

Classification of Tomato Fruit Using Yolov5 and Convolutional Neural Network Models.

Four deep learning frameworks consisting of Yolov5m and Yolov5m combined with ResNet50, ResNet-101, and EfficientNet-B0, respectively, are proposed for classifying tomato fruit on the vine into three categories: ripe, immature, and damaged. For a training dataset consisting of 4500 images and a training process with 200 epochs, a batch size of 128, and an image size of 224 × 224 pixels, the prediction accuracy for ripe and immature tomatoes is found to be 100% when combining Yolo5m with ResNet-101. Meanwhile, the prediction accuracy for damaged tomatoes is 94% when using Yolo5m with the Efficient-B0 model.

Combined Mueller matrix imaging and artificial intelligence classification framework for Hepatitis B detection.

Significance: The combination of polarized imaging with artificial intelligence (AI) technology has provided a powerful tool for performing an objective and precise diagnosis in medicine.

Aim: An approach is proposed for the detection of hepatitis B (HB) virus using a combined Mueller matrix imaging technique and deep learning method.

Approach: In the proposed approach, Mueller matrix imaging polarimetry is applied to obtain Mueller matrix images of 138 HBsAg-containing (positive) serum samples and 136 HBsAg-free (negative) serum samples.

The Ohmmeter Identifies the Site of Fluid Leakage during Artificial Urinary Sphincter Revision Surgery.

Purpose: While the AMS 800 artificial urinary sphincter improves continence in up to 90% of patients, revision surgery may be needed in up to 50%. We determined whether an ohmmeter could accurately assess the site of fluid leak from individual components of the artificial urinary sphincter at the time of revision surgery.

Materials And Methods: We retrospectively reviewed the records of patients who underwent artificial urinary sphincter revision surgery between 1996 and 2013.

Utilization of surgical procedures and racial disparity in the treatment of urinary incontinence after prostatectomy.

Aims: To analyze the rates of incontinence procedures after radical prostatectomy, and define the variables associated with them.

Methods: We conducted an IRB approved retrospective review of patients with prostate cancer who underwent radical prostatectomy at a single institute from January 1998 to December 2012. Logistic regression and time to event analyses were performed to ascertain variables associated with receipt of incontinence procedure after prostatectomy.

Long-term durability of the distal urethral polypropylene sling for the treatment of stress urinary incontinence: minimum 11-year followup.

Purpose: We report on the long-term outcomes of the distal urethral polypropylene sling for stress urinary incontinence in a patient cohort that was closely followed and whose outcomes were reported at 1 and 5 years after surgery.

Materials And Methods: We performed a prospective study of all consecutive patients who underwent a distal urethral polypropylene sling procedure between November 1999 and April 2000. The 1 and 5-year outcomes for this particular patient cohort were previously reported.

Surgical options for apical prolapse repair.

Pelvic organ prolapse is a common medical condition that affects the quality of life of many women. Approximately 50% of parous women have pelvic organ prolapse and the lifetime risk for surgical intervention is 6.7% at the age of 80 years.

Missed diagnosis of complete urethral transection after sling: the case for translabial ultrasound.

Patients with complications of urethral sling placement for stress urinary incontinence are often treated for recurrent symptoms for years after initial reassuring evaluation. Translabial ultrasound is a noninvasive modality with minimal risks that can clearly diagnose urethral mesh complications. We present a 47-year-old premenopausal woman referred for treatment of urethral stricture and diverticulum 8 years after mesh sling placement.

Foreign body in the bladder 11 years after intravaginal pessary.

Vaginal pessaries used for symptomatic pelvic organ prolapse (POP) rarely develop complications when regularly monitored. However, many reports of complications of neglected pessaries have been described. Patients presenting with pessary complications report a variety of symptoms ranging from malodorous discharge or recurrent infections to more severe symptoms such as vaginal bleeding, complete urinary incontinence, or defecatory obstruction.

Expanding the Role of Neuromodulation for Overactive Bladder: New Indications and Alternatives to Delivery.

From the time that it was granted US Food and Drug Administration approval, neuromodulation has secured a firm position in the treatment algorithm for overactive bladder. With neuromodulation, physicians were able to bridge the gap between the two ends of the treatment spectrum (medical therapy and open surgery). Sacral nerve stimulation has been the most widely used form of neuromodulation.

Inertial effects on flow rate spectrum of diffuser micropumps.

This study develops a diffuser micropump and characterizes its output flow rates, such as the parabola shape on the frequency domain and the affecting factors. First, an equivalent circuit using electronic-hydraulic analogies was constructed. Flow rate analysis results were then compared to experimental results to verify the applicability of the circuit simulation.

Effect of pulse width on object movement in vitro using holmium:YAG laser.

Background And Purpose: The holmium:YAG laser is an effective modality for intracorporeal lithotripsy. The fiber tip needs to be in contact with the calculus for maximal effect. Laser energy can cause stone retropulsion, necessitating cumbersome repositioning of the fiber.
