Adapted physical activity for breast cancer patients: shared considerations with two Olympic and world Italian sports champions.

Breast cancer is a growing global public health concern. Thanks to the recent treatments progress, the survival rate of BC patients has significantly improved (88% of 5-year survival rate) and the number of cancer survivors has also increased. Notwithstanding these brilliant results, many BC patients have long-term side effects as pain, oedema, limited mobility, cancer related fatigue, etc. as a consequence of surgical, radiotherapy and medical treatments. For example, posture appears to be frequently altered after mastectomy, due to the impairment of the mobility of the arm caused by surgical scars. All these aspects negatively affect the health-related Quality of Life (QoL) of BC patients. Recent several randomized clinical trials have shown benefits of regular and appropriate physical activity (PA) during and after BC treatment, particularly in terms of benefits for health, reducing fatigue, improving strength levels, QoL and physical function. In this context, two types of sports have demonstrated their affinity and efficacy as treatment support during and after treatments for BC patients: fencing and rowing. Here we report considerations shared with two sport champions: the fencing Olympic gold medal Daniele Garozzo and the rowing World Champion Giovanni Ficarra, with the aim to find the adapted PA for BC patients.

Fatigue in post-acute sequelae of SARS-CoV2 (PASC) treated with oxygen-ozone autohemotherapy - preliminary results on 100 patients.

OBJECTIVE: Post-acute sequelae of SARS-CoV2 infection (PASC) are a novel terminology used to describe post-COVID persistent symptoms, mimicking somehow the previously described chronic fatigue syndrome (CFS). In this manuscript, we evaluated a therapeutical approach to address PASC-derived fatigue in a cohort of past-COVID-19 positive patients. PATIENTS AND METHODS: A number of 100 patients, previously diagnosed as COVID-19 positive subjects and meeting our eligibility criteria, was diagnosed having PASC-related fatigue. They were recruited in the study and treated with oxygen-ozone autohemotherapy (O2-O3-AHT), according to the SIOOT protocol. Patients' response to O2-O3-AHT and changes in fatigue were measured with the 7-scoring Fatigue Severity Scale (FSS), according to previously published protocols. RESULTS: Statistics assessed that the effects of O2-O3-AHT on fatigue reduced PASC symptoms by 67%, as a mean, in all the investigated cohort of patients (H = 148.4786 p < 0.0001) (Figure 1). Patients following O2-O3-AHT therapy, quite completely recovered for PASC-associated fatigue, a quote amounting to about two fifths (around 40%) of the whole cohort undergoing ozone treatment and despite most of patients were female subjects, the effect was not influenced by sex distribution (H = 0.7353, p = 0.39117). CONCLUSIONS: Ozone therapy is able to recover normal functionality and to relief pain and discomfort in the form of PASC-associated fatigue in at least 67% of patients suffering from post-COVID sequelae, aside from sex and age distribution.

Jennet milk production during the lactation in a Sicilian farming system.

In Italy, the interest for jennet milk production has recently developed. An 18-month-long experiment was carried out on a jennet farm near Milo (CT), where 24 jennets, which derived from the Ragusana breed, were tested for milk yield and composition over an entire lactation period. The jennets were fed with hay and concentrate in a large paddock. From the 28th post-foaling day to the end of the lactation, the jennets were machine-milked twice a day with an in-between milking interval of 5 h. The milk amount from each jennet was recorded every 3 weeks and individual samples were collected and analyzed for fat, protein, casein, non-proteic nitrogen, lactose and somatic cell count. This study showed that jennets at Sicilian latitudes are not seasonal polyestrous. The daily milk yield, the length of lactation and the milk characteristics varied depending on the foaling season. The total average milk production was 490 ± 36 kg in 295 ± 12 post-foaling days, considering two milking records per day. During the lactation, milk yield decreased constantly from 1.98 to 1.28 kg/jennet per day. When looking at the jennet milk quality during lactation, the percentage of fat and protein decreased, while the lactose percentage increased, according to a tendency apparently unique for equines when compared to the ruminants. When looking at the productive season, spring generally gave the best qualitative and quantitative results. Based on these results, jennet milk yield and quality could be improved; furthermore, jennet milk production may turn out to be a profitable business.

Five-year follow-up of a cognitive-behavioural lifestyle multidisciplinary programme for childhood obesity outpatient treatment.

OBJECTIVE: Aim of this study is to examine the 5-year follow-up results of MI PIACE PIACERMI (I like to like and please myself), a cognitive-behavioural programme intended to obtain a weight growth regulation over an extended period. DESIGN: Longitudinal observational clinical study. SETTING: Hospital-based programme, through outpatient activities. SUBJECTS: Thirty-one simple obese children, 13 boys and 18 girls, 6-12 years of age on admission. INTERVENTION: The intervention was carried out by a multidisciplinary team (paediatrician, cognitive-behavioural psychologist, physical therapist). It employed cognitive-behavioural techniques, nutrition education, promotion of physical activity, setting a high value on free play in motion. The programme actively involves parents. The following measurements were taken on admission and at 5-year follow-up: height, weight, waist circumference, body mass index (BMI), BMI standardized (BMI-SDS), and adjusted BMI (a-BMI) as actual BMI/BMI (50th percentile)*100. Dietary habits were investigated by interview and 24-h recall. Parents completed the Family Habit Inventory and the Child Behaviour Checklist (CBCL). Motor skills were assessed by using Frostig's test. RESULTS: The dropout rate was 35.5%. In subjects who completed the 5-year follow-up, the mean and s.d. of BMI-SDS and a-BMI were, respectively, 4.23+/-0.71 and 54.7%+/-9.0 at baseline and 2.74+/-0.85 and 43.2%+/-17.3 at the last visit. Waist circumference decreased. Family habits improved significantly. Total energy intake was significantly reduced. Emotional and social aspects of obesity-related behaviours showed positive changes. Motor skills globally improved. CONCLUSIONS: The study provides further evidence that positive persistent results may be obtained in obese children with treatment programmes combining a lifestyle centred approach, parental involvement, nutrition education and cognitive-behavioural strategies.

Bone quality assessed by phalangeal quantitative ultrasonography in children and adolescents with isolated idiopathic growth hormone deficiency.

OBJECTIVE: Some observations indicate that GH deficiency (GHD) may have little impact on bone mineralization in contrast to its effects on bone growth and maturation. The aim of the present study was to evaluate the effects of isolated GHD and GH-replacement therapy on bone quality assessed by a quantitative ultrasound (QUS) technique at the proximal phalanges of the hand. DESIGN: Growth and QUS data of 68 subjects (50 males and 18 females) aged 5-18 yr with isolated GHD were retrospectively examined. A cross-sectional series of 120 observations was collected and compared with data obtained from a control population (1227 healthy children, 641 males and 586 females, aged 3-16 yr). METHODS: QUS variables amplitude- dependent speed of sound (AD-SoS) and bone transmission time (BTT) were assessed by the sonographic device DBM Sonic BP IGEA. Height and weight measurements were performed according to standard techniques. In patients, skeletal age (SA) was determined by Tanner-Whitehouse method (3rd version). RESULTS: Before treatment height, SA, ADSoS and BTT were reduced in patients. Height SD score (SDS), SA SDS, AD-SoS SDS, and BTT SDS improved during treatment. Significant associations of both AD-SoS and BTT with age, SA, height, and therapy duration were observed. Using multivariate regression models the disease state, SA, and height proved to be significant variables in predicting BTT and AD-SoS. CONCLUSIONS: QUS measurements adjusted for body size and skeletal maturity in GHD patients seem to be only slightly reduced. A body size and skeletal maturity adjustment should be incorporated in studies on bone mass in GHD children and adolescents. A non-invasive technique such as QUS technology opens new perspectives.

Longitudinal assessment of bone quality by quantitative ultrasonography in children and adolescents.

Among the techniques available to assess bone quality, quantitative ultrasonography of the proximal phalanges of the hand (QUS) has emerged as particularly attractive. In this study, amplitude-dependent speed of sound (AD-SoS) and bone transmission time (BTT) were obtained by the sonographic device DBM Sonic BP IGEA in two sessions at two years' interval, in a school-age population (589 subjects, 290 mol/L and 299F, aged 3 to 16 y) with the aim to determine accuracy of QUS measurements, evaluate QUS variable changes during growth, relate these values with age and growth variables. Mean AD-SoS and BTT at age classes from 5 to 12 y as determined at the first and second measurement sessions were not significantly different. A significant increment (p < 0.0001) between the first and the second measurement was observed for both QUS variables. AD-SoS and BTT showed significantly different variations in the various age groups (ANOVA). Correlations were found of AD-SoS and BTT increments with age, height, weight, pubertal stage and with height growth velocity (p < 0.05). AD-SoS and BTT increment curves presented a very similar trend decreasing from 4 to 7 y of age. Thereafter a plateau was reached up to the age of 10 to 11 y in girls and 11 to 12 y in boys, when an increase was observed corresponding to pubertal growth rate acceleration. In conclusion, the present study would confirm that QUS measurements are accurate. Ad-SoS and BTT increment models are similar to most growth velocity curves and follow a strongly age- and growth-dependent pattern.

Fetal spine ossification: the gender and individual differences illustrated by ultrasonography.

The spatial and temporal pattern of manifestation of ossification nuclei of the spinal column in fetal life have been well established by histologic and radiologic studies. Sonographic evaluation of the fetal spine depends on visualization of the ossification centers, but the sequence of development of ossification centers in the vertebral column obtained by embryologists and sonographers and radiology are conflicting. We carried out a longitudinal study to establish the ultrasonographic appearance and timing of development of primary ossification centers of the fetal spine in the first and second trimesters of pregnancy. A total of 80 mothers were evaluated during their pregnancy with two echographic controls; in the first trimester, the spine length was measured and, in the second trimester of pregnancy, the timing of ossification of the bodies and neural arches of sacral vertebrae and the difference in appearance between the female and male genders were evaluated. Spinal length measurements obtained in the first trimester and percentage of detection of sacral vertebral structures increased progressively with a regular pattern in relation to gestational age. Spinal length at first ultrasound examination was slightly correlated with time of appearance of sacral bodies and arches. Ossification timing was significantly earlier in females than in males. The study has attempted to improve our understanding of the sonographic detection of the spinal ossification. Data presented give some further information on the stages of appearance of sacral vertebrae body centers during intrauterine development. Differences between genders and interindividual variations in ossification timing were observed at a very early stage of development. This could be of value when fetal growth is evaluated. Moreover, further knowledge of spinal development may be useful for early diagnosis of spinal abnormalities and for fetal biometrics.

Transvaginal administration of progesterone.

OBJECTIVE: To examine the endometrial effects of three different doses of progesterone administered vaginally. METHODS: Forty women 25-41 years old deprived of ovarian function received estradiol (E2) for 28 days. From days 15 to 27, a new mucus-like vaginal gel of progesterone was administered every other day, randomly, dosed at 45 mg (group A, n = 14), 90 mg (group B, n = 13), or 180 mg (group C, n = 13). Plasma gonadotropins, estrone, E2, and progesterone were measured. An endometrial biopsy was performed on day 20 (n = 20) or 24 (n = 20) for endometrial dating and for estrogen and progesterone receptor determinations. RESULTS: Plasma estrogen levels were in the menstrual cycle range. Mean progesterone levels were lower in group A (2.4 +/- 0.2 ng/mL) than in group B (3.6 +/- 0.2 ng/mL) or C (3.4 +/- 0.4 ng/mL) (P < .005). Plasma FSH and LH decreased significantly during progesterone treatment. In all groups, we observed secretory transformation in the glands (day 20) and stroma (day 24) and the distribution of estrogen and progesterone receptors seen in normal menstrual cycles. CONCLUSION: Transvaginal administration of progesterone induced normal secretory transformation of the endometrium despite low plasma levels, suggesting a direct transit into the uterus or "first uterine pass effect."

[Physiopathology of maternal and feto-neonatal thyroid in pregnant women with endemic goiter]. / Fisiopatologia della tiroide materna e feto-neonatale nelle gravide con gozzo endemico.

Endemic goitre is a socially important disease in many regions of Italy. In conditions of euthyroidism, the course of pregnancy and perinatal outcome are not burdened by significant complications. It is useful to control thyroid function and to start L-thyroxine therapy in order to avoid any further increase in thyroid size owing to the goitrogenic effect of pregnancy and to avoid transient hypothyroidism and the nodular evolution of goitre. Recent studies appear to indicate a possible physiological role for thyroid hormones in the development of the fetal CNS as early as conception, an additional motive for the administration of thyroxine in order to prevent pathologies caused by thyroid hormone deficiency in utero.

[Ovarian stimulation using a protocol of low dose agonist in patients with an elevated basal FSH]. / Utilisation d'un protocole agoniste faible dose chez les patientes ayant une FHS de base élevée.

This study compare the ovarian response of patients with high day 3 FSH (> 6.5 UI/L), treated with two protocols; a protocol with a low dose of GnRH agonist and a so called "long protocol" with GnRH agonist in a depot formula. The ovarian response with the agonist low dose was better with less ampules (37.1 vs 46.6) and a shorter duration of stimulation (10.5 vs 12.4 days). The number of mature oocyte was higher (5.9 vs 4.5) as well as the number of good quality embryo (3.2 versus 2.3). The E2 levels on day 8 was higher (1065 vs 460 pg/ml). The cancellation rate was lower (14% vs 26%). The use of the low dose protocol gave a better ovarian response for patients with high 3 FSH. Large randomized studies are needed to confirm these data.

A protocol using a low dose of gonadotrophin-releasing hormone agonist might be the best protocol for patients with high follicle-stimulating hormone concentrations on day 3.

We studied 98 in-vitro fertilization (IVF) patients with a high basal follicle stimulating hormone (FSH; >6.5 IU/l) concentration on day 3 who were treated with a low dose gonadotrophin-releasing hormone agonist (GnRHa) protocol and who had received in the previous 6 months a long protocol with GnRHa in a depot formula. The evaluation was made using the previous IVF cycle of the same patient as a control. The mean +/- SD age of the patients was 34.1+/-4.2 years. The use of a low dose agonist protocol ended with significantly less ampoules (37.5 versus 46.1), a shorter duration of stimulation (10.7 versus 12.3 days), a higher oestradiol concentration on day 8 (1068 versus 495 pg/ml), a higher number of mature oocytes (5.9 versus 4.4) and a higher number of good quality embryos (3.3 versus 2.3). The cancellation rate was lower (11 versus 24%). A GnRHa low dose protocol may be the protocol of choice for patients with high FSH concentrations on day 3. Larger randomized studies are needed to confirm these data.

Immunolocalization, binding, and biological activity of endothelin in rabbit uterus: effect of ovarian steroids.

Specific immunostaining for endothelin 1 (ET-1) was observed in the endometrium but not myometrium of rabbits. The staining was dramatically affected by subacute treatment with ovarian steroids: epithelial cells were predominantly positive in immature rabbits, whereas, in sex steroid-primed rabbits, ET-1 was mainly localized in the stromal compartment. Binding studies were performed in myometrium of estrogen-treated rabbits using labeled ET-1 and ET-3, the corresponding unlabeled peptides, and sarafotoxin b (SRTX). Mathematical modeling of experimental results indicates that two populations of sites are present in myometrium. One site (R1 = 1 pmol/mg protein) shows approximately the same affinity for ET-1, ET-3, and SRTX [dissociation constant (Kd) 100 pM], whereas the second site (R2 = 10 pmol/mg protein) selectively binds ET-1 (Kd 400 pM). According to binding studies, ET-1 was more potent than SRTX in stimulating uterine contraction "in vitro." The subacute administration of increasing concentrations of 17 beta-estradiol (0.2-200 micrograms/kg for 4 days), but not 17 beta-estradiol (200 micrograms/kg for 4 days) plus progesterone (5 mg/kg for 4 days), stimulates a dose-dependent increase in endothelin receptors in myometrium (half-maximal effective dose = 0.7 micrograms/kg for 4 days). However, estrogen treatment does not affect the concentration of endothelin receptors in myometrial cells in primary culture. Conversely, divalent ions like calcium and magnesium enhance the binding of ET-1 to both uterine membranes and cells. Our results indicate that in rabbit uterus endothelin is present in the endometrium, whereas specific receptors are located in myometrium.

Human myometrium during pregnancy contains and responds to V1 vasopressin receptors as well as oxytocin receptors.

We have recently demonstrated the presence of two classes of neurohypophysial hormone receptors in the vagina, myometrium, and oviduct of rabbit: an oxytocin (OT) site and a V1 arginine vasopressin (AVP) site. We now report binding and in vitro contractility studies on human myometrial specimens obtained at cesarean section from women at the end of pregnancy. The program Ligand was used to analyze self- and cross-displacement curves for labeled OT, AVP or its V1 antagonist d(CH2)5TyrMeAVP, the corresponding unlabeled peptides, and selective analogs. Our results clearly indicate the presence of heterogeneity of binding sites in human uterus. Blocking experiments were performed to evaluate the density of OT and V1 AVP receptors in individual uterine specimens. The contractile response of the same samples to OT, AVP, and analogs was also evaluated. Our results indicate that V1 AVP receptors are present in all of the uterine specimens investigated, with virtually equal density from 32 weeks to term. AVP and the V1-selective agonist [Phe2,Ile3,Orn8]VP stimulate contractility of uterine strips, an effect blocked by nanomolar concentration of the V1 antagonist d(CH2)5TyrMeAVP. Uterine OT receptors increase during late pregnancy, peaking in early labor. A significant correlation between the density of OT receptors and the frequency of uterine contractions (external tocography) was found in pregnant women before surgery. OT stimulated in vitro contractility of uterine strips only when the density of receptors was more than 150 fmol/mg protein. In conclusion, we identified biologically active V1 AVP receptors in human uterus at the end of gestation and confirmed the primary relevance of OT receptors in human parturition.

Vasopressin and oxytocin receptors in vagina, myometrium, and oviduct of rabbits.

In view of the presence of distinct oxytocin (OT) and vasopressin (VP) receptors in the male genital tract (porcine) we have reexamined the receptors for OT and AVP in the classical OT target tissue, female genital tract (rabbit). Neurohypophysial hormone receptors have been investigated in vagina, myometrium, and oviduct using quantitative ligand binding, adenylate cyclase, and contractility studies. Our results clearly indicate the presence of distinct OT and V1 VP receptors in the myometrium, while only the latter was detected in vagina and oviduct. In myometrium, estrogen treatment increases the density of OT and AVP receptors, while progesterone administration inhibits the estrogen effect. At the time of spontaneous delivery a dramatic (17-fold) increase was observed for the OT sites, while the AVP sites were unchanged. AVP receptors in vagina were sensitive to sex steroid administration and were reduced during pregnancy and delivery. Isometric contractility studies suggest that not just OT, but AVP can stimulate uterine strips, an effect that is partially reversible by the V1 antagonist d(CH2)5TyrMeAVP. In vagina only AVP is effective in inducing contractions at nanomolar concentrations. These results suggest a role for AVP as well as OT in regulation of the motility of female genital tract.
