Determinants of weight, psychological status, food contemplation and lifestyle changes in patients with obesity during the COVID-19 lockdown: a nationwide survey using multiple correspondence analysis.

INTRODUCTION: The corona virus disease 2019 (COVID-19) pandemic forced most of the Italian population into lockdown from 11 March to 18 May 2020. A nationwide survey of Italian Clinical Nutrition and Dietetic Services (Obesity Centers or OCs) was carried out to assess the impact of lockdown restrictions on the physical and mental wellbeing of patients with obesity (PWO) who had follow-up appointments postponed due to lockdown restrictions and to compare determinants of weight gain before and after the pandemic. METHODS: We designed a structured 77-item questionnaire covering employment status, diet, physical activity and psychological aspects, that was disseminated through follow-up calls and online between 2 May and 25 June 2020. Data were analyzed by multiple correspondence analysis (MCA) and multiple linear regression. RESULTS: A total of 1,232 PWO from 26 OCs completed the questionnaires (72% female, mean age 50.2 ± 14.2 years; mean BMI 34.7 ± 7.6 kg/m2; 41% obesity class II to III). During the lockdown, 48.8% gained, 27.1% lost, while the remainder (24.1%) maintained their weight. The mean weight change was +2.3 ± 4.8 kg (in weight gainers: +4.0 ± 2.4 kg; +4.2% ± 5.4%). Approximately 37% of participants experienced increased emotional difficulties, mostly fear and dissatisfaction. Sixty-one percent reduced their physical activity (PA) and 55% experienced a change in sleep quality/quantity. The lack of online contact (37.5%) with the OC during lockdown strongly correlated with weight gain (p < 0.001). Using MCA, two main clusters were identified: those with unchanged or even improved lifestyles during lockdown (Cluster 1) and those with worse lifestyles during the same time (Cluster 2). The latter includes unemployed people experiencing depression, boredom, dissatisfaction and increased food contemplation and weight gain. Within Cluster 2, homemakers reported gaining weight and experiencing anger due to home confinement. CONCLUSIONS: Among Italian PWO, work status, emotional dysregulation, and lack of online communication with OCs were determinants of weight gain during the lockdown period.

Efficacy and safety of fibrin sealant patch in the treatment of air leakage in thoracic surgery.

AIM: Air leakage represents a major problem in lung surgery. Absorbable fibrin sealant patch (AFSP), a collagen sponge coated with human fibrinogen and thrombin, can be used as an adjunct to primary stapling or suturing. This study compared the efficacy of AFSP with manual suturing after primary stapling. METHODS: This was a prospective, multicenter, randomized study. Patients undergoing lobectomy, bilobectomy, anatomical segmentectomy for lung cancer or wedge resection for pulmonary metastasis with air leakage grade 1 or 2 according to Macchiarini scale after stapler suture were randomized to receive AFSP or standard surgical treatment (ST). The primary endpoint was the reduction of intraoperative air leakage intensity. Duration of postoperative air leakage and number of days until removal of last chest drain were secondary endpoints. Safety was recorded for all patients. RESULTS: A total of 346 patients were enrolled in 14 centres, 179 of whom received AFSP and 167 ST. Intraoperative air leak intensity was reduced in 90.5% of AFSP patients and 82% of ST patients (P=0.03). A significant reduction in postoperative air leakage duration was observed in the AFSP group (P=0.0437). The median number of days until removal of last drainage was 6 (3-37) in the AFSP group and 7 (2-27) in the ST (P=0.38). Occurrence of adverse events was comparable in both groups. CONCLUSION: AFSP was more efficacious than standard ST as an adjunct to primary stapling in reducing intraoperative air leakage intensity and duration of postoperative air leakage in patients undergoing pulmonary surgery. AFSP was well tolerated.

Utility of breast ultrasonography in the diagnostic work-up of precocious puberty and proposal of a prognostic index for identifying girls with rapidly progressive central precocious puberty.

OBJECTIVE: To determine the utility of breast ultrasono- graphy in the diagnostic work-up of precocious puberty and to create a prognostic index for early differentiation between non/slowly progressive or transient forms of precocious puberty and rapidly progressive central precocious puberty. METHODS: We recruited consecutively 60 girls with precocious pubertal development. In all the girls we evaluated Tanner stage, basal and gonadotropin-releasing hormone (GnRH)-stimulated follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels, estradiol (E2) levels, and bone age, and performed pelvis and breast ultrasound examinations. Logistic regression models were fitted to identify possible diagnostic factors for rapidly progressive central precocious puberty and non/slowly progressive or transient forms. RESULTS: Ultrasound breast volume>or=0.85 cm3 was associated with rapidly progressive central precocious puberty (P=0.01). Uterine volume>or=5 cm3, LH peak>or=7 IU/L, presence of an endometrial echo, E2 levels>or=50 pmol/L and bone age>2 SD above expected were significantly associated with rapidly progressive central precocious puberty. A multivariate model including uterine volume, E2 level, bone age, presence of an endometrial echo and ultrasound breast volume revealed a strong ability to classify rapidly progressive forms. From this multivariate analysis a prognostic index for rapidly progressive central precocious puberty was defined. CONCLUSIONS: Ultrasound imaging allows better definition of the breast and the maturation stage than does use of Tanner's stages. Ultrasound breast volume>or=0.85 cm3 is an independent predicting factor of rapidly progressive central precocious puberty. A prognostic index that was created from a multivariate model including uterine volume, E2 level, presence of an endometrial echo, bone age and ultrasonographically determined breast volume, may help in the early differentiation between rapidly progressive central precocious puberty and non/slowly progressive or transient forms.

Prevalence of metabolic syndrome (MS) in children and adolescents with varying degrees of obesity.

OBJECTIVE: Childhood obesity is increasingly common and is associated with health problems; in particular, obesity plays a central role in the metabolic syndrome (MS). We estimated the prevalence of MS in Caucasian children and adolescents with varying degrees of obesity. PATIENTS AND METHODS: We studied 191 obese [body mass index (BMI) > 97th percentile] children and adolescents. Obesity was stratified on the basis of a threshold BMI z-score and subjects were classified as moderately (z-score 2-2.5) or severely obese (z-score > 2.5). Seventy-six, nonobese subjects were recruited into a comparison group. Thirty-one of them were of normal weight (BMI < 75th percentile) and 45 overweight (BMI 75th-97th percentile). Patients were classified as having MS if they met three or more of the following criteria for age and sex: BMI > 97th percentile, triglyceride levels > 95th percentile, high density lipoprotein (HDL) cholesterol level < 5th percentile, systolic or diastolic blood pressure > 95th percentile and impaired glucose tolerance (blood glucose level: 7.8-11.1 mmol/l at 2 h). Insulin resistance was calculated using the homeostasis model assessment for insulin resistance (HOMA-IR) and impaired insulin sensitivity was defined as a HOMA-IR > or = 2.5 in prepubertal patients and HOMA-IR > 4 in pubertal subjects. RESULTS: The overall prevalence of MS was 13.9% and was present in 12.0% of moderately obese and 31.1% of severely obese subjects; no overweight or normal weight subjects met the criteria for MS. The rate of the MS increased progressively with increasing BMI categories (P < 0.001). Severely obese patients had a threefold increased risk with respect to moderately obese patients. CONCLUSIONS: The prevalence of the MS is higher in obese as opposed to nonobese subjects and increases with severity of obesity.

Final height in short polytransfused thalassemia major patients treated with recombinant growth hormone.

We measured the final height (FH) of 25 short polytransfused thalassemia major (Th) patients (18 males) with a reduced GH reserve treated for 3.3 +/- 1.2 yr with recombinant GH (rhGH), 0.2 mg/kg/week sc. At baseline, all patients were clinically prepubertal; their chronological (CA) and bone ages (BA) were 13.6 +/- 2.0 and 11.4 +/- 1.6 yr, respectively. In 9 out of 18 males and 5 out of 7 females, the onset of puberty occurred spontaneously during the treatment. At the end of the rhGH administration, the height of the enrolled children was not significantly increased when calculated for CA (HxCA), while it was significantly decreased (p=0.004) when calculated for BA (HxBA); the BA increase (3.29 +/- 1.65 yr) was significantly higher (p<0.001) than the height age increase (2.16 +/- 0.98 yr). The FHxCA showed a significant increase (p=0.001) compared to both baseline and the end of therapy, while the FHxBA was significantly decreased (p<0.001) compared with the corresponding value at baseline. At the end of therapy, both HxCA and HxBA resulted positively related to the BA at baseline (r=0.50 and 0.42, p=0.012 and 0.034, respectively). FH was positively correlated with CA (r=0.63, p=0.001), BA (r=0.68, p<0.001) and HxBA (r=0.59, p=0.002) evaluated at baseline, and with both HxCA and HxBA (r=0.82 and 0.74, respectively, p<0.001), evaluated at the end of treatment. A negative correlation was found between FH and the length of treatment (r=-0.56, p=0.004). Our data seem to exclude that prolonged rhGH therapy could improve FH in Th patients; on the contrary, a negative effect may be hypothesized.

On the outcome in stroke patients one year later: the role of atrial fibrillation.

The post-stroke aftermath of patients suffering from atrial fibrillation (AF) is investigated. A total of 104 consecutive patients (80 with AF and 24 without AF) were referred to a rehabilitation centre and enrolled. They underwent a rehabilitative programme. Disability was assessed by using the Functional Independence Measure (FIM), at the time of admission, discharge and after 1 year. Death was more frequent over the 1-year interval in AF group. Ten patients died (42%), whereas in the non-AF group death occurred in 15 cases (19%). By using chi-square test, the difference was significant (P < 0.02). The logistic regression analysis indicated that the unique variable affecting the FIM at follow-up was the FIM at discharge (P < 0.0001). AF was not a significant variable in the equation. The result can be attributed to subject attrition in the AF group, as the most severe patients died and survivors could benefit from a better functional status.

Recombinant growth hormone treatment in short patients with thalassemia major: results after 24 and 36 months.

Treatment with recombinant growth hormone (rhGH), 0.6 IU/kg/week s.c., previously successfully conducted for one year, was continued in 15 (Group A) and 8 (Group B) short thalassemia major patients with reduced GH reserve, for two and three years, respectively. In Group A, height for chronological age (Ht SDSCA) increased significantly (p = 0.021) from the start of treatment, but the positive effect was only apparent because of the concomitant slight worsening of height for bone age (Ht SDSBA). Median deltaHt SDSCA/deltaHt SDSBA was <1.0 with respect to both the start (0.87) and the end of the first year of rhGH therapy (0.89). IGF-I levels increased significantly (p = 0.043) compared with values both at the start and at the end of the first year of rhGH therapy. In Group B neither Ht SDSCA nor Ht SDSBA differed statistically from starting values, the former having a positive trend and the latter a negative one. Median deltaHt SDSCA/deltaHt SDSBA was 0.92 with respect to the start, and 0.94 with respect to the end of the second year. IGF-I levels increased significantly (p = 0.043) with respect to starting values. Our data show that the encouraging results described from the first year of rhGH treatment did not persist during the second and third years, and we conclude that this is because increase in bone age with continued treatment is equal to, or slightly greater than the height age increase. We propose that patients with thalassemia major with short stature should receive rhGH treatment for only one year, and that more prolonged treatment should be reserved for selected adolescents who have psychological problems due to shortness; for these patients growth acceleration could represent the main goal, even if this leads to a substantially unchanged or slightly decreased final height.

Etiology and age incidence of precocious puberty in girls: a multicentric study.

We review the etiology and age incidence of precocious puberty in 438 girls examined between 1988-1998; 428 (97.7%) had central precocious puberty (CPP), the remaining 10 (2.3%) gonadotropin-independent precocious puberty (GIPP) of ovarian origin. The majority of CPP girls (59.6%) were aged between 7-7.9 yr, 22.4% were 6 year olds, and only 18% were under 6 years old. Cranial CT and/or MRI performed in 304/428 girls, showed neurogenic abnormalities in 56/304 (18.4%) CPP girls; 30 (9.9%) were due to previously diagnosed intracranial abnormalities and the remaining 26 (8.5%) were detected at the diagnosis of CPP. The frequency of neurogenic CPP tended to be higher in girls under 4 years of age while the frequency of idiopathic CPP tended to be higher in girls aged between 7-7.9 years, but no statistically significant differences were found. Interestingly, some CNS anomalies either of tumoral or congenital origin were detected at presentation in 7% of the girls aged over 7 years. Other related or coincidental clinical anomalies, mainly due to genetic diseases, were observed in 22/304 (7.2%) patients. History of precocious maternal menarche was found in 12/304 (4%) girls. In conclusion, idiopathic CPP was observed in 74% of the girls in this study. Neurogenic anomalies or other coincidental or related clinical findings were observed in the remaining 26%. The increased frequency of idiopathic CPP in girls aged over 7 years may suggest an early, but otherwise normal onset of puberty in many of these girls as a consequence of the trend towards earlier maturation. Nonetheless, the finding of CNS anomalies also in the older patients, raises the question of whether these patients should undergo a complete diagnostic work-up.

Etiology of central precocious puberty in males: the results of the Italian Study Group for Physiopathology of Puberty.

We reviewed the hospital records of 45 boys, followed in 13 pediatric departments throughout Italy, who had undergone computed tomography and/or magnetic resonance imaging for central precocious puberty (CPP). Twenty-seven patients (60%) had idiopathic CPP and 18 (40%) neurogenic CPP. A hamartoma of the tuber cinereum was found in six patients (33%). All patients with hypothalamic hamartoma had earlier onset of symptoms than patients with idiopathic CPP. Five patients (27%) were affected by type 1 neurofibromatosis, two had ependymoma and five patients had an intracranial anomaly. Basal LH and basal and peak LH/FSH ratio were greater, but not significantly, in boys with neurogenic CPP than in boys with idiopathic CPP. The highest LH peak levels were observed in patients with hamartoma; however, no correlation was observed between LH peak and the size of the hamartomas. In addition, bone age at diagnosis was more advanced in patients with hamartoma than in patients with other conditions. In conclusion, gonadotrophin-dependent precocious puberty may be of idiopathic origin or may occur in association with any CNS disorder. Further studies are needed in order to evaluate the effects of nutritional, environmental and psychosocial factors on the timing of sexual maturation, to explain the high incidence of idiopathic CPP in our male patients.

When to stop GnRH analog therapy: the experience of the Italian Study Group for Physiopathology of Puberty.

Data reported in this study have been recently published elsewhere. The authors retrospectively analyzed the auxological response to GnRH agonist treatment and the final height (FH) outcome in 71 girls with idiopathic and truly precocious (onset before 8 years) central puberty (CTPP), who had been treated with the same therapy protocol (Decapeptyl Depot at the dose of 60 microg/kg i.m. every 28 days) for at least 2 years (since 7.0 +/- 1.3 yr) and followed until puberty was completed and FH was reached. During the entire treatment period we observed: A) a decrease of height standard deviation scores (SDS) (from 1.5+/-1.7 to 0.9+/-1.3 SDS, p<0.01); B) a striking deceleration of BA, revealed by the subnormal deltaBA:deltaCA ratio (0.2 +/- 0.1); C) an increase of predicted adult height (from 155.6+/-7.0 to 160.7+/-6.7 cm, p<0.0005). Treatment interruption was followed by notable catchdown growth, with FH (158.4 +/- 5.8 cm) lower (p < 0.025) with respect to that predicted at the end of therapy. However FH fell within the population norm and the target range in 87.3% and 90% of patients, respectively. The tallest FH was recorded in the patients who discontinued treatment at a BA of 12.0-12.5 years. We conclude that: 1) Most girls with idiopathic CTPP treated by GnRH agonists may achieve an adult height within the population norm and/or their target range; 2) The height gain from therapy onset until FH attainment, however, is generally rather limited (on average 2.9 cm) and only few patients are able to reach their target percentile; 3) The most favorable height prognosis with respect to target height (TH) is generally observed in the patients with the tallest H2 and the lowest BA2:CA2 ratio, due to the notable deterioration of height prognosis which frequently follows therapy interruption; 4) In order to strengthen the weak therapeutic effect of GnRH agonists in CTPP, this treatment should be discontinued at a BA of 12-12.5 years.

End results in central precocious puberty with GnRH analog treatment: the data of the Italian Study Group for Physiopathology of Puberty.

We report some end results with GnRH agonist (GnRHa) treatment in central precocious puberty (CPP), in terms of final height (FH), ovarian function, peak bone mass, body composition and psychological problems. The two studies reported (Study I and II) are part of the activity of the Italian Study Group for Physiopathology of Puberty. Study L Growth data were analyzed of three groups of patients: treated with i.n. spray buserelin, i.m. triptorelin and untreated. Both GnRHa administration modes were effective in arresting pubertal development and all girls had complete recovery of the reproductive axis after therapy. Treated patients showed an improvement in final height in comparison with untreated patients and compared to predicted height at the start of treatment with both agonist treatments. However, patients treated with the long-acting slow release preparation had a better improvement in adult height and reached or exceeded the genetic height potential. Study II. In a retrospective evaluation of the outcome in 71 girls with idiopathic CPP treated with triptorelin, we found that FH fell within the population norm and the target range in 87.3% and 90% of the patients respectively. The tallest FH was recorded in the patients who started therapy at less than 6 years of age and in those who discontinued treatment at a bone age of 12.0-12.5 yr. Finally, we and other groups have recently found normal values of bone mineral density in girls at the end of GnRHa treatment in the great majority of patients.

Factors influencing final/near-final height in 12 boys with central precocious puberty treated with gonadotrophin-releasing hormone agonists. Italian Study Group of Physiopathology of Puberty.

Gonadotrophin-releasing hormone agonists (GnRHa) have been demonstrated as the therapy of choice for central precocious puberty (CPP). Few studies have provided male patients' adult height data. In our multicenter study we evaluated long-term effects of different GnRHa preparations and final/near-final height (FH) in 12 boys with CPP and analyzed the factors influencing FH. Patients' mean chronological age at the time of diagnosis was 7.6 +/- 0.9 yr. Three patients were treated only with triptorelin at a mean dose of 90 microg/kg i.m. every 28 days. Nine patients initially received buserelin (at a mean initial dose of 53.4 microg/kg/day i.n. divided into 3-6 equal doses) or buserelin (at a mean dose of 36.7 microg/kg/day s.c.) and were subsequently switched to triptorelin. The GnRHa therapy was continued for 4.1 +/- 0.6 yr (range 2.9-5.4). The mean predicted adult height increased from 169.9 +/- 4.2 cm at diagnosis to 180.7 +/- 6.0 cm at the end of treatment. Mean FH was 176.1 +/- 6.1 cm (170.1-190.7), corresponding to mean SDS(CA) 0.4 +/- 0.8 (-0.6/2.5), mean SDSBA 0.2 +/- 0.9 (-0.6/2.4) and mean corrected SDS for target height of 0.4 +/- 0.6 (-0.8/1.2). Multiple regression analysis revealed that FH was mainly influenced by target height and height at discontinuation of GnRHa therapy. The present data indicate that GnRHa therapy significantly improves growth prognosis in boys with CPP and fully restores genetic height potential.

Birth weight influences long-term catch-up growth and height prognosis of GH-deficient children treated before the age of 2 years.

OBJECTIVE: To investigate which pretreatment variables most significantly affect long-term growth response to GH therapy in children with apparently idiopathic GH deficiency (GHD) treated from a similar and very young age (less than 2 years), for the same period (7 years) and with the same therapeutic protocol. DESIGN AND METHODS: Twelve children with either isolated GHD or multiple pituitary hormone deficiency were treated with biosynthetic human GH (0.7IU/kg per week) and were examined every 6 months. Height measurements were performed by Harpenden stadiometers. Bone age was evaluated every 12 months. RESULTS: The onset of therapy was followed in all patients by an important height gain, which attained its zenith during the first year of treatment and became progressively less evident during the next 4 years. Cumulative height gain was 3.0+/-1.7SDS. Thanks to the therapy, at the end of the 7-year treatment period, average height in the entire series was not significantly far from mean target height (TH) (-0.7+/-1.3 vs -0. 3+/-0.4SDS) and average predicted height (PH) (-0.2+/-1.4SDS) was very close to TH. A stepwise regression analysis showed that both catch-up growth under therapy and PH at the end of the 7-year treatment period were positively influenced by birth weight (BW). CONCLUSIONS: a) Our 7-year prospective study on GHD infants treated with GH from less than 2 years of age confirmed the importance of early diagnosis and treatment of GHD in childhood. b) The influence of BW on growth response to GH therapy in GHD children persists over time, at least when treatment is begun from less than 2 years of age.

Phase I/II study of gemcitabine plus vinorelbine as first-line chemotherapy of non-small-cell lung cancer.

PURPOSE: To determine the maximum-tolerated dose of gemcitabine when combined with a fixed dose of vinorelbine in the treatment of non-small-cell lung cancer (NSCLC) and to evaluate in a phase II trial the activity of this combination. PATIENTS AND METHODS: Sixty-eight patients with stage IIIB/IV NSCLC were treated with vinorelbine at fixed dose of 30 mg/m(2) intravenously and gemcitabine at increasing dose levels from 800 to 1,500 mg/m(2) intravenously on days 1 and 8 every 3 weeks. RESULTS: In phase I, dose-limiting toxicity occurred at the dosage of 1,500 mg/m(2) gemcitabine, with three of five patients developing grade 4 thrombocytopenia. In phase II, with gemcitabine at 1,200 mg/m(2), 19 (36%) of 52 assessable patients responded. Objective response was observed in 11 (39%) of 28 patients with stage IIIB disease and in eight (33%) of 24 patients with stage IV. The median time to progression was 29 weeks (range, 2 to 41 weeks; 35 weeks and 16 weeks for stages IIIB and IV, respectively), and median survival was 54 weeks (range, 2 to 84+ weeks; 63 weeks and 42 weeks for stages IIIB and IV, respectively). One-year survival was 64% for patients with stage IIIB disease and 29% for those with stage IV. Clinical benefit response was observed in 29 (59%) of 49 assessable patients. Grade 4 leukopenia and thrombocytopenia were uncommon (6% and 8% of cases, respectively); however, grade 3/4 leukothrombocytopenia occurred more frequently in patients aged more than 70 years (52% and 24%, respectively). CONCLUSION: The combination of vinorelbine and gemcitabine is effective and tolerable in the treatment of NSCLC, thus deserving randomized trials with cisplatin combination regimens.
