- Stress is a normal part of life for fungi, which can survive in environments considered inhospitable or hostile for other organisms. Due to the ability of fungi to respond to, survive in, and transform the environment, even under severe stresses, many researchers are exploring the mechanisms that enable fungi to adapt to stress. The International Symposium on Fungal Stress (ISFUS) brings together leading scientists from around the world who research fungal stress. This article discusses presentations given at the third ISFUS, held in São José dos Campos, São Paulo, Brazil in 2019, thereby summarizing the state-of-the-art knowledge on fungal stress, a field that includes microbiology, agriculture, ecology, biotechnology, medicine, and astrobiology.

- PURPOSE: Serum levels of the inflammatory markers YKL-40 and interleukin 6 (IL-6) are increased in many conditions, including cancers. We examined serum YKL-40 and IL-6 levels in patients with Hodgkin lymphoma, a tumor with strong immunologic reaction to relatively few tumor cells, especially in nodular sclerosis Hodgkin lymphoma. EXPERIMENTAL DESIGN: We analyzed Danish and Swedish patients with incident Hodgkin lymphoma (N=470) and population controls from Denmark (n=245 for YKL-40; n=348 for IL-6). Serum YKL-40 and IL-6 levels were determined by ELISA, and log-transformed data were analyzed by linear regression, adjusting for age and sex. RESULTS: Serum levels of YKL-40 and IL-6 increased in Hodgkin lymphoma patients compared with controls (YKL-40, 3.6-fold; IL-6, 8.3-fold; both, P<0.0001). In pretreatment samples from pretreatment Hodgkin lymphoma patients (n=176), levels were correlated with more advanced stages (P(trend), 0.0001 for YKL-40 and 0.013 for IL-6) and in those with B symptoms; however, levels were similar in nodular sclerosis and mixed cellularity subtypes, by EBV status, and in younger (<45 years old) and older patients. Patients tested soon after treatment onset had significantly lower levels than pretreatment patients; however, even >or=6 months after treatment onset, serum YKL-40 and IL-6 levels remained significantly increased compared with controls. In patients who died (n=12), pretreatment levels for YKL-40 and IL-6 were higher than in survivors, although not statistically significantly. CONCLUSIONS: Serum YKL-40 and IL-6 levels were increased in untreated Hodgkin lymphoma patients and those with more advanced stages but did not differ significantly by Hodgkin lymphoma histology. Following treatment, serum levels were significantly lower.

- The efficacy of mid-urethral sling (MUS) surgery in older women and women with a significant disease burden is limited. We aimed to determine the influence of chronological age and physical status (assessed by the American Society of Anesthesiologists Physical Status, ASA) classification on outcomes.Cure rate, change in frequency of lower urinary tract symptoms, satisfaction, impact, and adverse events after MUS surgery were assessed in 5200 women aged 55-94 years with MUS surgery (2010-2017). Data were analysed by multivariate logistic regression and Mantel-Haenszel chi-square statistics.The cure rate was 64.2% (95% CI, 60.0-68.4) in the ≥ 75-year cohort compared to 88.5% (95% CI, 87.1-89.8) in the 55-64-year cohort (trend p < 0.0001). The estimated probability of cure, improvement, and satisfaction with the procedure decreased by aOR10yr = 0.51 for cure to aOR10yr = 0.59 for satisfaction (all p < 0.0001). Women with a significant health burden (ASA class 3-4) had lower cure rates and satisfaction than those without (65.5% vs. 83.7%, p < 0.0001 and 65.7% vs. 80.6%, p < 0.0001). Older age was more likely to be associated with de novo urgency (p = 0.0022) and nocturia ≥ 2 (p < 0.0001). Adverse events, readmission, and 30-day mortality rates were low. Women, irrespective of age, were equally satisfied if they experienced a decrease of at least one step in leakage frequency.Even if MUS surgery in older women and those with ASA class 3-4 was associated with a lower cure rate and less satisfactory outcome, a majority were satisfied provided they experienced a reduction of incontinence episodes.

- The long-term effects of vaginal delivery, parity, and pregnancy on the pelvic floor remain uncertain and controversial issues. In comparison with studies using self-reported symptoms, surgical register data may offer a more valid means for evaluating the relative influence of these risk factors.This study used data from 3 high-quality nationwide registers, namely the Swedish National Quality Register of Gynecological Surgery, the Swedish Medical Birth Register, and the Total Population Register, to evaluate the contribution of vaginal and cesarean delivery, parity, and factors not related to childbirth to the long-term risk for reconstructive urogenital surgery.This was a register-based linkage study among women aged ≥45 years who underwent urinary incontinence or prolapse surgery from 2010 to 2017. This surgical cohort was divided into nulliparous women, women with ≥1 cesarean deliveries only, those with ≥1 vaginal deliveries, and according to the number of births. A corresponding reference group was constructed based on women born in 1960 from the Total Population Register (n=2,309,765). The Swedish Medical Birth Register was used to determine the rate of women with cesarean and vaginal delivery and their respective parity. Absolute and relative risk were presented per 1000 women with 95% confidence intervals. Pairwise differences were analyzed with Fisher exact tests and the Mann-Whitney U test for dichotomous and continuous variables. The trend between ≥3 ordered categories of dichotomous variables was analyzed with Mantel-Haenszel statistics.A total of 39,617 women underwent prolapse surgery and 20,488 underwent incontinence surgery. Among women with prolapse surgery, 97.8% had ≥1 vaginal delivery, 0.4% had ≥1 cesarean delivery only, and 1.9% were nullipara. Corresponding figures for those with incontinence surgery were 93.1%, 2.6%, and 4.3%, respectively. Women with vaginal deliveries were overrepresented in the prolapse surgery (relative risk, 1.23; 95% confidence interval, 1.22-1.24; P<.001) and incontinence surgery groups (relative risk, 1.17; 95% confidence interval, 1.15-1.19; P<.001). Nulliparous and cesarean delivered women were underrepresented in the prolapse surgery (relative risk, 0.14; 95% confidence interval, 0.13-0.15 and relative risk 0.055; 95% confidence interval, 0.046-0.065; all P<.001) and incontinence surgery groups (relative risk, 0.31; 95% confidence interval, 0.29-0.33 and relative risk, 0.40; 95% confidence interval, 0.36-0.43). The absolute risk for prolapse surgery was lowest after cesarean delivery (0.09 per 1000 women; 95% confidence interval, 0.08-0.11) and differed by a factor of 23 (absolute risk, 2.11 per 1000 women; 95% confidence interval, 2.09-2.13) from that after vaginal birth. The absolute risk for prolapse and incontinence surgery increased consistently with parity after vaginal births. This trend was not observed after cesarean delivery, which is on par with that of nulliparous women. The first vaginal birth contributed the highest increase in the absolute risk for pelvic organ prolapse surgery (6-fold) and stress urinary incontinence surgery (3-fold). The second vaginal birth contributed the lowest increase in the absolute risk for pelvic organ prolapse surgery (∼1/3 of the first vaginal birth) and for stress urinary incontinence surgery (∼1/10 of the first vaginal birth).Surgery for urinary incontinence and prolapse was almost exclusively related to vaginal parity. The risk for prolapse surgery increased consistently with parity after vaginal births but not after cesarean delivery, whereas the risk associated with cesarean delivery was on par with that of nulliparous women. Thus, cesarean delivery seems to offer protection from the need for pelvic organ prolapse and stress urinary incontinence surgery later in life.

- The development of advanced prosthetic devices that can be seamlessly used during an individual's daily life remains a significant challenge in the field of rehabilitation engineering. This study compares the performance of deep learning architectures to shallow networks in decoding motor intent for prosthetic control using electromyography (EMG) signals. Four neural network architectures, including a feedforward neural network with one hidden layer, a feedforward neural network with multiple hidden layers, a temporal convolutional network, and a convolutional neural network with squeeze-and-excitation operations were evaluated in real-time, human-in-the-loop experiments with able-bodied participants and an individual with an amputation. Our results demonstrate that deep learning architectures outperform shallow networks in decoding motor intent, with representation learning effectively extracting underlying motor control information from EMG signals. Furthermore, the observed performance improvements by using deep neural networks were consistent across both able-bodied and amputee participants. By employing deep neural networks instead of a shallow network, more reliable and precise control of a prosthesis can be achieved, which has the potential to significantly enhance prosthetic functionality and improve the quality of life for individuals with amputations.
