The experience of fertility concerns in patients with testicular cancer: a qualitative study.

BACKGROUND: Testicular cancer usually occurs in young adult men between the ages of 20 and 40 years, which largely coincides with the age of men's reproductive intentions. However, a serious side effect of testicular cancer therapy could reduce the fertility of patients. PURPOSE: To explore the experience of fertility concerns in patients with testicular cancer. METHODS: A phenomenological research was conducted on 12 patients with testicular cancer. Data collection was from May 2023 to August 2023, and Colaizzi analysis method was used to analyze the data. RESULTS: Four themes were found: (1) multiple worries and negative emotions, (2) fertility decision-making faces many challenges, (3) self-coping strategies for facing fertility concerns, (4) unmet supportive care needs. CONCLUSION: Medical staff should pay attention to the fertility needs of patients with testicular cancer and provide relevant interventions and support to reduce their fertility concerns.

A case report of Vibrio vulnificus sepsis in a diabetic patient.

Vibrio vulnificus is a facultative anaerobic, alkalophilic, halophilic, mesophilic, Gram-negative bacterium that can cause severe wound infection, sepsis and diarrhea. This paper reported a case of 85-year-old male patient infected with Vibrio vulnificus due to being stabbed by a sea shrimp. This patient also had diabetes with a long history of alcoholism. Due to bacterial pathogenicity and the patient's underlying diseases, his condition deteriorated rapidly. Based on the rapid diagnosis of Vibrio vulnificus using the next-generation sequencing（NGS）technology and blood culture method, as well as the selection of the most effective antibiotics via drug sensitivity test, this patient underwent precise antimicrobial treatment, thorough debridement and drainage within the shortest possible time, and thus the prognosis of this patient was greatly improved. In this paper, we have systematically explored the epidemiology, clinical features, diagnosis and treatment of Vibrio vulnificus infection, thus providing a practical reference for the clinicians to quickly identify and treat possible Vibrio vulnificus infection in diabetic patients after contacting with sea water or seafood.

Successful management of exudate and odor using a pouch system in a patient with malignant facial wound: A case report.

Malignant fungating wounds are associated with heavy exudate and malodor, and can thus have a devastating impact on the physical, psychological, and functional health of patients at the end of life. Management is typically limited to the use of more absorbent dressings and frequent changing of dressings. However, this method is associated with a large amount of time needed for wound care, and does not always resolve the problem of malodor. Herein, we report the use of an inexpensive ostomy pouch to manage facial fungating wounds caused by maxillary gingival carcinoma. The pouches are adhered to the skin, and collect a large amount of malodorous exudate for days without leaking. Fewer dressing changes and the absence of malodor result in an improved quality of life for the patient and family.

[Effect of Protein Kinase A Activation on Aggregation Function of Platelets].

OBJECTIVE: To investigate the effect of protein kinase A (PKA) activation on aggregation funetion of platelets in vitro. METHODS: The peripheral blood of healthy adults were collected, and the washed platelets were gained from collected peripheral blood. The washed platelets were treated with PKA activator Forskolin, then the platelet aggregation was induced by using Ristocetin, Thrombin, Collagen and ADP respectively, the platelet aggregation level was detected by the platelet aggregator. RESULTS: Compared with the controls, 5 µmol/L forskolin significantly inhibited ADP and collagen-induced platelet aggregation (P＜0.001), and showed mild inhibiting effect on Thrombin-induced platelet aggregation (P＜0.05). 2.5-10 µmol/L forskolin significantly inhibited ADP and Collagen -induced platelet aggregation (P＜0.001); but not showed significantly inhibitory effects on Ristocetin-induced platelet aggregation (P＞0.05). CONCLUSION: PKA activation inhibits agonists-induced platelet aggregation.

Akt-mediated platelet apoptosis and its therapeutic implications in immune thrombocytopenia.

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by low platelet count which can cause fatal hemorrhage. ITP patients with antiplatelet glycoprotein (GP) Ib-IX autoantibodies appear refractory to conventional treatments, and the mechanism remains elusive. Here we show that the platelets undergo apoptosis in ITP patients with anti-GPIbα autoantibodies. Consistent with these findings, the anti-GPIbα monoclonal antibodies AN51 and SZ2 induce platelet apoptosis in vitro. We demonstrate that anti-GPIbα antibody binding activates Akt, which elicits platelet apoptosis through activation of phosphodiesterase (PDE3A) and PDE3A-mediated PKA inhibition. Genetic ablation or chemical inhibition of Akt or blocking of Akt signaling abolishes anti-GPIbα antibody-induced platelet apoptosis. We further demonstrate that the antibody-bound platelets are removed in vivo through an apoptosis-dependent manner. Phosphatidylserine (PS) exposure on apoptotic platelets results in phagocytosis of platelets by macrophages in the liver. Notably, inhibition or genetic ablation of Akt or Akt-regulated apoptotic signaling or blockage of PS exposure protects the platelets from clearance. Therefore, our findings reveal pathogenic mechanisms of ITP with anti-GPIbα autoantibodies and, more importantly, suggest therapeutic strategies for thrombocytopenia caused by autoantibodies or other pathogenic factors.
