Installing oncofertility programs for common cancers in limited resource settings (Repro-Can-OPEN Study): An extrapolation during the global crisis of Coronavirus (COVID-19) pandemic.

PURPOSE: The state of limited resource settings that Coronavirus (COVID-19) pandemic has created globally should be taken seriously into account especially in healthcare sector. In oncofertility, patients should receive their fertility preservation treatments urgently even in limited resource settings before initiation of anticancer therapy. Therefore, it is very crucial to learn more about oncofertility practice in limited resource settings such as in developing countries that suffer often from shortage of healthcare services provided to young patients with cancer. METHODS: As an extrapolation during the global crisis of COVID-19 pandemic, we surveyed oncofertility centers from 14 developing countries (Egypt, Tunisia, Brazil, Peru, Panama, Mexico, Colombia, Guatemala, Argentina, Chile, Nigeria, South Africa, Saudi Arabia, and India). Survey questionnaire included questions on the availability and degree of utilization of fertility preservation options in case of childhood cancer, breast cancer, and blood cancer. RESULTS: All surveyed centers responded to all questions. Responses and their calculated oncofertility scores showed different domestic standards for oncofertility practice in case of childhood cancer, breast cancer, and blood cancer in the developing countries under limited resource settings. CONCLUSIONS: Medical practice in limited resource settings has become a critical topic especially after the global crisis of COVID-19 pandemic. Understanding the resources necessary to provide oncofertility treatments is important until the current COVID-19 pandemic resolves. Lessons learned will be valuable to future potential worldwide disruptions due to infectious diseases or other global crises.

The role of bacterial stimuli in inflammation-driven bone formation.

Immune cells and their soluble factors regulate skeletal cells during normal bone regeneration and pathological bone formation. Bacterial infections can trigger immune responses that activate pro-osteogenic pathways, but these are usually overshadowed by osteolysis and concerns of systemic inflammation. The aim of this study was to determine whether the transient local inflammatory reaction to non-viable bacterial immune agonists could lead to favourable new bone formation. In a series of rabbit studies, as proof-of-concept, how tibial intramedullary injection of viable or killed bacterial species affected bone remodelling and new bone formation was determined. Application of killed bacteria led to considerable new bone formation after 4 weeks, without the prolonged systemic inflammation and exaggerated bone lysis seen with active infection. The osteo-immunomodulatory effects of various species of killed bacteria and the dose response relationship were subsequently screened in ectopically-implanted ceramic scaffolds. Histomorphometry after 8 weeks showed that a relatively low dose of killed bacteria enhanced ectopic bone induction. Moreover, lipoteichoic acid - the bacterial cell-wall derived toll-like-receptor (TLR)-2 activator - was identified as an osteo-stimulatory factor. Collectively, the data indicated that bacterial stimuli could be harnessed to stimulate osteogenesis, which occurs through a synergy with osteoinductive signals. This finding holds promise for the use of non-viable bacteria, bacterial antigens, or their simplified analogues as immuno-modulatory bone regenerating tools in bone biomaterials.

Accuracy of preoperative real-time dynamic transvaginal ultrasound sliding sign in prediction of pelvic adhesions in women with previous abdominopelvic surgery: prospective, multicenter, double-blind study.

OBJECTIVE: To investigate the role of the transvaginal sonographic (TVS) sliding sign in predicting pelvic adhesions in women with previous abdominopelvic surgery. METHODS: This was a multicenter, prospective, interventional, double-blind study of patients with a history of abdominopelvic surgery who were undergoing laparoscopy or laparotomy during the 6-month period from March to August 2016 in one of three academic obstetrics and gynecology departments. Prior to surgery, patients were examined by TVS to assess the vesicouterine pouch, uterus, ovaries and pouch of Douglas, using the TVS pelvic sliding sign. Ultrasound findings and medical and surgical data were recorded. We assessed the accuracy of the preoperative TVS sliding sign in the prediction of pelvic adhesions overall and in each compartment separately. RESULTS: During the study period, complete TVS sliding sign and laparoscopic or laparotomic data were available for 107 women. Their mean age was 44.0 (95% CI, 41.6-46.4; range, 20-79) years. Their mean parity was 2.0 (95% CI, 1.7-2.3; range, 0-9) and the mean number of previous abdominal surgical procedures per patient was 1.3 (95% CI, 1.2-1.5; range, 1-4). Adhesions were noted in 27/107 (25.2%) patients. The TVS sliding sign had a sensitivity of 96.3% and specificity of 92.6% in predicting pelvic adhesions. There was a significant relationship between adhesions in each compartment and the TVS sliding sign (P < 0.05). CONCLUSIONS: The TVS sliding sign is an effective means to detect preoperatively pelvic adhesions in patients with previous abdominopelvic surgery. Use of such a non-invasive and well-tolerated technique could help in the planning of laparoscopy or laparotomy and counseling of these patients. Copyright © 2017 ISUOG.

Host suitability analysis of the bark beetle Scolytus amygdali (Coleoptera: Curculionidae: Scolytinae).

Scolytus amygdali is a polyphagous insect pest that feeds on fruit trees and forest trees. Our study assessed the host preference and reproductive potential of S. amygdali on four tree species: almond (Prunus dulcis), apricot (Prunus armeniaca), peach (Prunus persica), and plum (Prunus domestica). Females of S. amygdali produced maternal galleries that were longer on peach than the other three trees, and female fecundity was highest on peach. Females with longer maternal galleries produced more eggs, indicating a positive correlation between maternal gallery length and female fertility. The under-bark development time of S. amygdali is significantly shorter on plum (45 days) and almond (56 days) than on apricot (65 days) and peach (64 days). Despite this longer development time on peach, our results still suggest that, of the four types of tree tested, peach is the most preferred host for S. amygdali.

Does bacterial colonization during embryo transfer have an impact on pregnancy rate in ICSI? : Tunisian preliminary results.

INTRODUCTION: Embryos' transfer into the uterine cavity remains a limiting factor in the success of intracytoplasmic sperm injection (ICSI). This study aimed to evaluate the impact of cervico-vaginal colonization on ICSI outcomes. MATERIEL AND METHODS: Longitudinal, prospective and analytical study, conducted from February 1 st to October 31 st, 2017. On the day of embryos' transfer, patients with the following criteria were included: Age ≤ 40, normal uterine ultrasound and hysteroscopy, first or second attempt of ICSI, use of fresh semen and transfer of at least one good quality embryo. Three samples were done for microbiological analysis: vaginal secretions, cervical mucus and the tip of the transfer catheter. RESULTS: The study included 40 patients. Pregnancy rate was 52.5 %. Catheter contamination occurred in nine cases (22.5 %). The most frequently isolated bacteria were Streptococcus anginosus (37 % of cases), Gardnerella vaginalis (27 % of cases) and Streptococcus agalactiae (18 % of cases). In all cases of contamination, the same bacteria were found also in the vagina and cervical mucus. In cases of contamination with Gardnerella vaginalis, the study of vaginal flora showed bacterial vaginosis. No pregnancy was obtained when contamination of the transfer catheter occurred. In the absence of contamination, pregnancy rate was 61.2 % (ρ = 0.003). Both populations (patients with catheter contamination and patients without catheter contamination) were comparable regarding epidemiological characteristics and ICSI attempt data. CONCLUSION: Contamination of the transfer catheter by cervical-vaginal bacteria appears to affect IVF results. Systematic antibiotic prophylaxis could be proposed to reduce this negative impact.

[Primary vesicoureteral reflux: report of 100 pediatric observations]. / Le reflux vésico-urétéral primitif: à propos de 100 observations pédiatriques.

In this study, the authors have reported 100 cases of primary vesico-ureteral reflux (VUR) which occurred over a 7-year period. Patient age at presentation ranged from 1 month to 13 years, with a mean age of 3 years and 5 months. Overall, a higher rate of reflux was observed in the female population (63%) which was particularly evident after the age of 3 years, but with a male predominance during the first 12 months of life. In the majority of cases, the diagnosis of VUR was made following diagnosis and investigation of urinary infection (UI). A high level of UI was the most frequent sign of VUR (87% of cases), while in 6% of cases this disorder was diagnosed during the investigation of an uropathy which was found to be complex in all subjects. An analysis of 143 ureteral reflux units (URU) showed that VUR was pathological only in 17% of cases, and that the reflux grade was I, II, III and IV in 47.4, 28.14, 11.11 and 2.34% of cases respectively. DMSA scintigraphy in 38 patients showed signs of nephropathy in 24 cases, i.e., 14 scars and a decrease in kidney size in 9 cases, and an absence of fixation for one grade IV reflux. Forty subjects with 56 reflux units (34 grade I, II and 22 grade III, IV) were treated by antibiotic prophylaxis, with a positive outcome in 85% of cases in children under 2 years of age, compared to 40% for children aged over 2 years. Only 7 patients were treated by teflon endoscopic injection, and in one case a further injection was required; 21 patients with 30 reflux units were treated by surgery at a mean age of 4 years. In conclusion, VUR is a fairly common disorder, which is frequently detected via an IU; its potential gravity is associated with the risk of subsequent nephropathy.

Olive orchard amended with olive mill wastewater: effects on olive fruit and olive oil quality.

The aim of this work was to study the effects of agronomic application of olive mill wastewater (OMW) in a field of olive trees on olive fruit and olive oil quality. Agronomic application of OMW increased significantly the fungal:bacteria ratio, whereas the root colonisation and the photosynthetic rates decreased significantly. Consequently, the oil content expressed as a percentage of dry weight, decreased significantly after agronomic application of OMW. Land spreading of OMW altered the relative proportion of individual olive fruit sugar and decreased significantly the nitrogen (N) and phosphorus (P) of the fruit. A significant increase was observed in total phenol content of oil after agronomic application of OMW. alpha-Tocopherol content, on the contrary, decreased with OMW application. The fatty acid composition of the oil was not affected by the treatments. To our knowledge, this is the first report of change in the olive fruit and olive oil quality following agronomic application of OMW.

Serological screening for hydatidosis in households of surgical cases in central Tunisia.

Household members of surgical cases of hydatidosis were screened for the disease in two high-risk districts in Central Tunisia. Seventy-four index cases were identified from the 1980-1984 surgical records of Sousse University Hospital. Household members over five years of age were tested by ELISA, and if positive by counterelectrophoresis (CEP) for detection of band 5. Positive subjects underwent a chest X-ray and echotomography (ECT). Eight of the 355 household members (2.2%) living in four different houses were serologically positive. All eight had a normal chest X-ray; a hepatic cyst was detected in seven of them. Five of the seven subjects in whom a cyst was diagnosed lived in two neighbouring houses (19 household members from the same family). Among these 19 subjects, six had been previously operated on for hydatidosis (cumulative rate: 11/19). The comparisons of these results with results obtained through community-based screening in the same area suggest that households members of patients are not at particularly high risk of hydatidosis.

[Seroepidemiologic study of toxoplasmosis in the school population of Sousse]. / Etude séroépidémilogique de la toxoplasmose dans la population scolaire de Sousse.

To obtain basic epidemiological data about toxoplasmosis in our area, we undertook a serological investigation of the female school population of Sousse City. 33% of the students in college (mean age: 17.8 years) are seronegatives. Social economic status seems not to be important for the risk of infection. The more important source of contamination may be the soil.
