Botulism is a neuroparalytic disease most commonly caused by foodborne ingestion of neurotoxin types A, B, and E, and is often fatal if untreated. Clinicians should be able to recognize the classic symptoms of botulinum intoxication (12). Bemnifosbuvir manufacturer Owing to its rarity, there are a limited number of studies evaluating the clinical care of patients with wound botulism (10). We present an infected tibial non-union with botulism who underwent a successful radical excision and bone transport. The patient tolerated the procedure well.
Does the association of basal FSH and anti-Müllerian hormone (AMH) concentrations with post-IVF/intracytoplasmic sperm injection (ICSI) live birth change with maternal age?

A total of 2003 IVF/ICSI patients were stratified according to basal FSH/AMH in concordant favourable (CF; AMH >1ng/ml and FSH ≤10IU/l), concordant unfavourable (CU; AMH ≤1ng/ml and FSH >10IU/l), discordant with favourable AMH (DFA) and discordant with favourable FSH (DFF) groups, as well as according to age in pre-advanced maternal age (pre-AMA; <35), AMA-1 (≥35, ≤37), AMA-2 (>37, ≤40) and AMA-3 (>40). IVF/ICSI outcomes were compared among CF, CU, DFA and DFF groups, and the association of basal FSH and AMH concentrations with live birth was tested by univariate and multivariate analysis in total, pre-AMA and AMA groups, separately.

Different outcome patterns were observed in discordant AMH/FSH groups from different age categories; favourable basal FSH concentrations were associated with higher delivery rates in pre-AMA patients, but with lower delivery rates in AMA groups. Within pre-AMA patients, DFF patients presented higher delivery rates but lower oocyte yield compared with DFA patients. In the univariate analysis, favourable AMH (P<0.02) and oocyte yield (P<0.002) were positively associated with live birth in all AMA groups. The multivariate analysis revealed that favourable basal FSH, but not AMH or oocyte yield, is associated with live birth in pre-AMA patients independently of other variables (P = 0.012).

The relationship of basal FSH and AMH with IVF/ICSI success changes with maternal age; basal FSH better reflects clinical outcomes probably determined by oocyte quality in pre-AMA patients, while AMH better suits AMA patients.

Do donor spermatozoa improve IVF outcomes after first oocyte donation failure?

Retrospective, multicentre study including couples undergoing oocyte donation cycles using autologous or donor spermatozoa after a failed first attempt. Male partners were further characterized as normozoospermic or oligoasthenoteratospermic, i.e. fewer than 5 million motile progressive spermatozoa in the ejaculate. The main outcomes measured were live birth rate (LBR) per embryo transfer, LBR per number of embryos transferred, and cumulative LBR (CLBR) considering oocytes consumed in the previous donation cycles.

Analysis comprised 6065 cycles of oocyte donation failure; among these, subgroup analyses by sperm quality comprised 4113 cycles with severe male factor and 1150 cycles with suboptimal/normal spermatozoa. Sperm replacement in the first cycle after failure increased LBR per embryo transfer (OR 2.21, 95% CI 1.7-2.8, P<0.001) and per number of embryos transferred (OR 2.46, 95% CI 1.9-3.1, P<0.001) for normospermic and oligoasthenoteratospermic men. Replacement by the third cycle after failure was less beneficial (LBR per embryo transfer OR 1.35, 95% CI 0.9-2.1, P = 0.16; LBR per embryos transferred OR 1.33, 95% CI 0.9-2.0, P = 0.186). Kaplan-Meier curves of CLBR per oocyte fertilized with autologous or donor spermatozoa were statistically different (P<0.001) and demonstrate how each additional oocyte may affect success based on sperm source (donor/autologous).

Donor spermatozoa improved outcomes when used after an initial failed oocyte donation cycle. The CLBR curves can be used to determine the cumulative chances of live birth using either autologous or donor spermatozoa, providing guidance on when to replace spermatozoa.

Does chronic stress affect the key proteins and sperm parameters of the blood-testis barrier (BTB)?

C57Bl/6 mice were divided into two groups a non-treated control group and a chronic unpredictable stress (CUS) applied group. The stress status of the animals was confirmed with behavioural tests. Histopathologic evaluation was conducted by haematoxylin and eosin staining and electron microscope. Malondialdehyde, corticosterone and testosterone levels were evaluated in peripheral blood. Expression levels of BTB proteins, namely zonula occludens-1 (ZO-1), claudin-11 (CLDN11) and clathrin in Sertoli cells, were assessed by Western blotting and immunofluorescence techniques. Sperm samples were collected from cauda epididymis, and sperm parameters analysed.

The stress model was confirmed by behavioural tests. Histopathological evaluation of the testes demonstrated a mild degeneration in seminiferous tubules. Malondialdehyde (P = 0.008) and corticosterone levels increased (P = 0.004) and testosterone levels decreased (P = 0.005) in the CUS group. Electron microscopic evaluation confirmed the damage in BTB integrity in the CUS group. Western blot analysis showed that ZO-1 and CLDN11 levels were significantly decreased, although clathrin levels were unchanged. Although sperm concentration and total motility rate were not significantly different between the groups, progressive motility (P = 0.03), normal sperm morphology (P = 0.04), chromatin integrity (toluidine blue) (P = 0.002) and the acrosomal reaction rate (P = 0.002) were significantly decreased, and acrosomal abnormality rate was dramatically increased (P = 0.04) in the CUS group.

In mice, CUS disrupted BTB integrity and impaired sperm parameters. A decrease in ZO-1 and CLDN11 expression levels may be proposed as the causative factor.
