Rationale:With advances in prenatal diagnostic techniques, chromosomal microdeletions and microduplications have become the focus of prenatal diagnosis. 7q partial monosomy or trisomy due to a deletion or duplication of the 7q end is relatively rare and usually originates from parents carrying a balanced translocation.Patient concerns:Noninvasive prenatal screening (NIPT) showed a fetus with partial deletion and duplication of chromosome 7q. It was not possible to determine whether the fetus was normal.Diagnoses:Conventional chromosome G-banding and chromosome microarray analysis (CMA) were performed on fetal amniotic fluid samples and parental peripheral blood samples.Interventions:The pregnant women were given detailed genetic counseling by clinicians.Outcomes:The fetal karyotype was 46, XY on conventional G-banding analysis. The CMA test results showed a deletion of approximately 7.8 Mb in the 7q36.1q36.3 region and a duplication of 6.6Mb in the 7q35q36.1 region. The parents’ karyotype analysis and CMA results were normal, indicating a new mutation.Lessons:CMA molecular diagnostic analysis can effectively detect chromosomal microdeletions or microduplications, clarify the relationship between fetal genotype and clinical phenotype, and provide a reference for prenatal diagnosis of chromosomal microdeletion-duplication syndrome.

We investigated the current state of frailty in elderly patients with tuberculosis and analyzed the factors that influence it. Using a convenience sampling method, 120 elderly patients with tuberculosis were selected from the Department of Infectious Diseases at Lishui Hospital of Traditional Chinese Medicine in Zhejiang Province. A cross-sectional survey was conducted using general demographic questionnaires, the FRAIL (fatigue, resistance, aerobic capacity, illnesses, and loss of weight) screening scale, the self-rating depression scale (SDS), and a questionnaire on respiratory function exercise adherence. The influencing factors for depression were analyzed using logistic regression. The average depression score of the 120 elderly patients with frailty and tuberculosis was 54.88 ± 5.61, indicating a mild level of depression. The correlation between this score and respiratory function exercise adherence was negative. According to a logistic regression analysis, marital status and payment methods were influencing factors for depression in these elderly patients with frailty and tuberculosis. There is a need to increase respiratory function exercise adherence among elderly patients with frailty and tuberculosis who have a high incidence of depression. Medical staff should assess adverse emotions in patients and their adherence to respiratory function exercises on a periodic basis.

Blood transfusion is a therapeutic act which consists of administering blood or one of its components (red blood cells, platelets and plasma), from one or more healthy subjects to a sick subject. Blood donation is a life-saving gesture that is highly encouraged but a source of pathologies which constitutes a real public health problem. Objective: To study the seroprevalence of viral markers among blood donors at the Gabriel Touré University Hospital in Mali. Method: Cross-sectional study from January 2020 to December 2021. This study was carried out at the CHU Gabriel Touré transfusion service in Mali on the results of blood donors. The donors were selected according to the criteria established by the National Blood Transfusion Center in Mali. Results: the prevalence of HIV, HBV, HCV and Syphilis were respectively 0.27%, 10.67%, 2.28% and 0.76% among all donors. The male gender dominated with a positive prevalence of 10.98% for HBV. The prevalence of HIV and Hepatitis B co-infection was the most represented with 0.27% collected. Conclusion: the prevalence of infectious agents among blood donors remains high in Bamako, Mali. This study suggests greater attention to raising awareness about testing for viral agents like HIV and hepatitis B.

Products containing cannabidiol (CBD) have proliferated after the 2018 Farm Bill legalized hemp (cannabis with ≤0.3% delta-9-tetrahydrocannabinol (Δ9-THC)). CBD-containing topical products have surged in popularity, but controlled clinical studies on them are limited. This study characterized the effects of five commercially available hemp-derived high CBD/low Δ9-THC topical products. Healthy adults (N = 46) received one of six study drugs: a CBD-containing cream (N = 8), lotion (N = 8), patch (N = 7), balm (N = 8), gel (N = 6) or placebo (N = 9; matched to an active formulation). The protocol included three phases conducted over 17 days: (i) an acute drug application laboratory session, (ii) a 9-day outpatient phase with twice daily product application (visits occurred on Days 2, 3, 7 and 10) (iii) a 1-week washout phase. In each phase, whole blood, oral fluid and urine specimens were collected and analyzed via liquid chromatography with tandem mass spectrometry (LC-MS-MS) for CBD, Δ9-THC and primary metabolites of each and pharmacodynamic outcomes (subjective, cognitive/psychomotor and physiological effects) were assessed. Transdermal absorption of CBD was observed for three active products. On average, CBD/metabolite concentrations peaked after 7-10 days of product use and were highest for the lotion, which contained the most CBD and a permeation enhancer (vitamin E). Δ9-THC/metabolites were below the limit of detection in blood for all products, and no urine samples tested "positive" for cannabis using current US federal workplace drug testing criteria (immunoassay cut-off of 50 ng/mL and confirmatory LC-MS-MS cut-off of 15 ng/mL). Unexpectedly, nine participants (seven lotions, one patch and one gel) exhibited Δ9-THC oral fluid concentrations ≥2 ng/mL (current US federal workplace threshold for a "positive" test). Products did not produce discernable pharmacodynamic effects and were well-tolerated. This study provides important initial data on the acute/chronic effects of hemp-derived topical CBD products, but more research is needed given the diversity of products in this market.

Uterine rupture (UR) during pregnancy is a serious obstetric complication. Here we report a case of spontaneous rupture in an unscarred uterus at 13 weeks of gestation after in vitro fertilization embryo transfer, which is not common in past references. Our focus is to understand the relationship between systemic lupus erythematosus (SLE) and UR. A 33-year-old infertile woman with a history of SLE became pregnant after in vitro fertilization embryo transfer. She presented with sudden mental fatigue and dyspnea, accompanied by sweating, dizziness and lower abdominal pain at 13 weeks of gestation. Blood analysis revealed anemia. Ultrasonography and plain computed tomography scan revealed intrauterine early pregnancy with effusion in pelvic and abdominal cavity. Laparotomy confirmed the diagnosis of UR. The patient underwent emergency laparotomy. Upon surgery, multiple myometrium was weak with only serosal layer visible, and there was a 2.5 cm irregular breach with exposed placenta and villous tissue in the posterior wall of the uterus. After removing intrauterine fetus and repairing the breach, there was still persistent intraperitoneal hemorrhage. The patient underwent subtotal hysterectomy finally. Postoperative recovery was uneventful. The patient was discharged on the 8th day after operation. Combined efforts of specialists from ultrasound, imaging and gynecologist led to the successful diagnosis and management of this patient. We should be cautious about the occurrence of unscarred uterus rupture during pregnancy of the women with the disease of SLE and long-term glucocorticoid treatment. In IVF, we had better transfer one embryo for these patients with the history of SLE. Obstetricians should strengthen labor tests to detect early signs of UR of the patients with SLE and long term glucocorticoid treatment. Once UR is suspected, prompt surgical treatment is needed as soon as possible.
