Respiratory Pathogen Coinfection During Intersecting COVID-19 and Influenza Epidemics.

Respiratory pathogen coinfections pose significant challenges to global public health, particularly regarding the intersecting epidemics of COVID-19 and influenza. This study investigated the incidences of respiratory infectious pathogens in this unique context. We collected throat swab samples from 308 patients with a fever from outpatient and emergency departments at sentinel surveillance hospitals in Xiamen, southeast of China, between April and May 2023, testing for SARS-CoV-2 and 26 other respiratory pathogens.

Effects of SARS-CoV-2 Vaccines on Sperm Quality: Systematic Review.

Background: The COVID-19 pandemic, caused by SARS-CoV-2, has triggered a global public health crisis of unprecedented proportions. SARS-CoV-2 vaccination is a highly effective strategy for preventing infections and severe COVID-19 outcomes. Although several studies have concluded that COVID-19 vaccines are unlikely to affect fertility, concerns have arisen regarding adverse events, including the potential impact on fertility; these concerns are plagued by limited and inconsistent evidence.

Effect of Team Health Education on Radiodermatitis in Patients with Head and Neck Tumor Radiotherapy Under the Joint Committee International Standards.

Objectives: This study aimed to investigate the impacts of team health education on radiodermatitis in patients undergoing head and neck radiotherapy.

Data Sources: A total of 118 patients undergoing radiotherapy at the Oncology Department of Qingdao Municipal Hospital under the Joint Committee International (JCI) accreditation standards of medical and health institutions were divided into two groups according to the order of the admission: the intervention group (n = 66) and the control group (n = 52). The patients in the control group were given routine nursing, while those in the intervention group received team health education based on the control group.

Prevention of hematogenous infection in peripheral venous catheterization with integrated medical assistance in patients undergoing chemotherapy.

Objective: This study is aimed at verifying the effect of specific management modalities aimed at reducing or preventing the incidence of infections in the blood flow in relation to the use of the central venous catheter (CRBSI = catheterrelated bloodstream infection) in patients undergoing chemotherapy.

Methods: 36 patients (n = 36) with a peripherally inserted venous catheter (PICC) were enrolled in the integrated medical treatment group, while 128 patients with an internal central venous catheter were enrolled in the control group. The patients in the control group underwent routine nursing, while the patients in the treatment group underwent integrated surveillance control infection treatment by doctors and were compared between these two groups l incidence of complications, CRBSI.

Thioclava atlantica sp. nov., isolated from deep sea sediment of the Atlantic Ocean.

A taxonomic study was carried out on strain 13D2W-2(T), which was isolated from a sulphur-oxidizing bacterial consortium, enriched by the deep-sea sediment of the Atlantic Ocean. The isolate was observed to be Gram-negative, oxidase- and catalase-positive, short rod-shaped and motile by means of a flagellum. Growth was observed at salinities from 0.

Indigenous oil-degrading bacteria in crude oil-contaminated seawater of the Yellow sea, China.

Indigenous oil-degrading bacteria play an important role in efficient remediation of polluted marine environments. In this study, we investigated the diversity and abundance of indigenous oil-degrading bacteria and functional genes in crude oil-contaminated seawater of the Dalian coast. The gene copy number bacterial 16S rRNA in total were determined to be about 10(10) copies L(-1) in contaminated seawater and 10(9) copies L(-1) in uncontaminated seawater.

Thioclava dalianensis sp. nov., isolated from surface seawater.

A taxonomic study was carried out on strain DLFJ1-1(T), which was isolated from an oil-degrading bacterial consortium, enriched by the surface seawater from around the Dalian Peninsula. The isolate was Gram-reaction-negative, oxidase- and catalase-positive, short-rod-shaped and non-motile. Growth was observed at salinities from 0.

[Correlation of recurrent pregnancy loss with sperm parameters and sperm DNA fragmentation].

Objective: To evaluate and compare standard sperm parameters and sperm DNA fragmentation in seminal ejaculates from men whose partners had a history of recurrent pregnancy loss (RPL) and a control group of men who had recently established their fertility.

Methods: Semen samples from 85 patients with a history of RPL and 20 men with proven fertility were analyzed according to World Health Organization guidelines. Sperm DNA fragmentation was detected by sperm chromatin dispersion test (SCD).

Relationship between varicocele and sperm DNA damage and the effect of varicocele repair: a meta-analysis.

Varicocele, a cause of male infertility, occurs in nearly 40% of infertile males. It has been postulated that varicoceles may cause sperm DNA damage. Sperm DNA integrity has been recognized as one of the important determinants of normal fertilization and embryo growth in natural and assisted conception.
