Background: Microsurgical total removal of vestibular schwannoma (VS) is the definitive treatment but has a high incidence of postoperative neurological deficits. Rotating Gamma Knife (RGK) is a preferred option for a small tumor. This study aims to evaluate long-term neurological outcomes of RGK for VS. Methods: This prospective longitudinal study was conducted at the Nuclear Medicine and Oncology Center, Bach Mai Hospital, Hanoi, Vietnam. Eighty-nine consecutive patients were enrolled from October 2011 to October 2015 and followed up to June 2017. RGK was indicated for VS measuring <2.2 cm, while RGK for tumors measuring 2.2–3 cm was considered in patients with severe comorbidities, high-risk surgery, and who denied surgery. Concurrently, VS consisted of newly diagnosed, postoperative residual, and recurrent tumors. Patients with neurofibromatosis type 2 were excluded from the study. Primary outcomes were radiological tumor control rate, vestibulocochlear functions, facial and trigeminal nerve preservation. Stereotactic radiosurgery was performed by the Rotating Gamma System Gamma ART 6000. Results: The tumors were measured 20.7 ± 5.6 mm at pre treatment and 17.6 ± 4.1 mm at 3-year post treatment. The mean radiation dose was 13.5 ± 0.9 Gy. Mean follow-up was 40.6 ± 13.3 months. The radiological tumor control rate was achieved 95.5% at 5-year post treatment. The hearing and vestibular functions were preserved in 70.3% and 68.9%, respectively. The facial and trigeminal nerve preservation rates were 94.4% and 73.3%, respectively. Conclusion: RGK is an effective and safe treatment for VS measuring ≤3 cm with no significant complications during long-term follow-up.

Background. The aim was to assess long-term dynamics and factors associated with the serological response against the Severe Acute Respiratory Syndrome Coronavirus 2 after primary infection. Methods. A prospective longitudinal study with monthly serological follow-up during the first 4 months, and then at 6, 8 and 10 months after the disease onset of all recovered adult in- and out-patients with Coronavirus Disease 2019 (COVID-19) attending Udine Hospital (Italy) during the first wave (from March to May 2020). Results. 542 individuals were included (289 female, mean age 53.1 years), mostly with mild COVID-19 (370, 68.3%). Patients were followed for a median of 302 days (Interquartile Range, 186-311). Overall seroconversion rate within two months was 32% for IgM and 90% for IgG. Seroreversion was observed in 90% of patients for IgM at 4 months and in 47% for IgG at 10 months. older age, number of symptoms at acute onset, severity of acute COVID-19, were all independent predictors of long-term immunity both for IgM (β, linear regression coefficient, 1.10, p=0.001; β 5.15 p=0.014; β 43.84 p=0.021, respectively) and for IgG (β 1.43 p<0.001; β 10.46 p<0.001; β 46.79 p<0.001, respectively), whereas the initial IgG peak was associated only with IgG duration (β 1.12, p <0.001). Conclusions. IgM antibodies disappeared at four months and IgG antibodies declined in about half of patients 10 months after acute COVID-19. These effects varied depending on the intensity of the initial antibody response, age and burden of acute COVID-19.

Abstract Surgical removal of the GH-secreting tumor is the initial treatment of choice for acromegaly. Outcome of surgery is assessed by measuring IGF-1 and glucose-suppressed GH levels. IGF-1 normalization is an essential biochemical criterion for remission. The cut-off for nadir GH after oral glucose that signifies remission, however, is debated. It also remains unclear whether GH levels provide additional prognostic or clinically relevant information when IGF-1 results are definitive. To address this question, we examined how initial postoperative glucose-suppressed GH levels change over time on serial testing in patients who achieve initial remission as defined by IGF-1 normalization. We studied 87 acromegaly patients (48M, 39F) who achieved a normal IGF-1 level after surgery alone longitudinally from 1996 to 2019. All had GH measured before and 60, 90 and 120 minutes after 75 or 100 mg oral glucose (OGTT) at ≥ 3 months after surgery and GH and IGF-1 repeated ≥ 1 year later. GH was by measured by sensitive, 22KDa GH specific assays, either a IRMA (DSL, International Reference Standard (IRS) 88/624) or a chemiluminescence immunoassay (IDS-iSYS, IRS 98/574). OGTT Nadir GH levels were also measured in healthy subjects; n=46 (26 M, 20 F, ages 19-71 yr.) by DSL and n=46 (29 M, 17 F; ages 20-66 yr.) by IDS-iSYS. Nadir GH levels in acromegaly patients were compared to the 95%CI of healthy subjects’ mean and categorized relative to healthy subjects’ 97.5 percentile, which was 0.14 µg/L for both assays. IGF-1 levels were compared to age and gender adjusted normal ranges. Subjects were grouped based on initial nadir GH ≤ or &gt; 0.14 µg/L and the patterns of change in nadir GH and IGF-1 at last follow up or until IGF-1 became elevated (i.e. recurrence). Follow up durations are given as median(range). In follow up, 73 patients remained in remission (normal IGF-1) and 14 had a recurrence (elevated IGF-1). Of the 73 in remission, 55 had initial nadir GH ≤ 0.14 µg/L that persisted to 10 yr.(1-22yr.) of follow up, 5 had initial GH ≤ 0.14 µg/L that rose to &gt; 0.14 µg/L by 9(3-21)yr., 10 had GH &gt; 0.14 µg/L that persisted at 5.5(2-22)yr., and 3 had GH &gt; 0.14 µg/L that fell to ≤ 0.14 µg/L at 5(4-7)yr. of follow up. Of the 14 that recurred, 11 had an initial and persistent GH &gt; 0.14 µg/L and developed an elevated IGF-1 level after 6(1-23) yr.. The 3 other patients that recurred had an initial GH ≤ 0.14 µg/L that rose to &gt; 0.14 µg/L by 1-6 years later and subsequently developed an elevated IGF-1 level by 14-16 years of follow up. In summary, we found that the pattern of normal IGF-1 along with nadir GH &gt; 0.14 µg/L on initial testing or developing with time, was associated with recurrence in 14/32 patients. We also found that initial nadir GH ≤ 0.14 µg/L was highly predictive of long-term persistent remission: 60/63 such patients remained in remission. In conclusion, glucose-suppressed GH levels are of prognostic value in acromegaly patients with normal IGF-1 after surgery.

Girls With Adhd

We describe the initiation and evolution of the Berkeley Girls with ADHD Longitudinal Study, an ongoing prospective, longitudinal study of 140 girls diagnosed with ADHD when they were children during the late 1990s, as well as 88 matched comparison girls. Study rationale, design, procedures, recruitment strategy, and measures are described in detail. Primary psychosocial and neuropsychological findings during childhood, adolescence, and adulthood are summarized. Our initial findings regarding predictors of outcome are presented. Results are discussed in light of the existing literature regarding long-term outcome among children with ADHD. Overall, during childhood, adolescence, and young adulthood, in almost every psychosocial and neuropsychological domain we investigated, females with ADHD show sizable disadvantages and deficits relative to females without ADHD. Our findings affirm the public health significance of ADHD in girls, given the likelihood of persisting symptoms and (especially) impairment in crucial domains over the long-term.

Abstract Background Forced migrants can be exposed to various stressors that can impact their health and wellbeing. How the different stages in the migration process impacts health is however poorly explored. The aim of this study was to examine changes in self-rated health (SRH) and quality of life (QoL) among a cohort of adult Syrian refugees before and after resettlement in Norway. Method We used a prospective longitudinal study design with two assessment points to examine changes in health among adult Syrian resettlement refugees in Lebanon accepted for resettlement in Norway. We gathered baseline data in 2017/2018 in Lebanon and subsequently at follow-up one year after arrival. The main outcomes were good SRH measured by a single validated item and QoL measured by WHOQOL-BREF. We used generalized estimating equations to investigate changes in outcomes over time and incorporated interaction terms in the models to evaluate effect modifications. Results In total, 353 subjects participated in the study. The percentage of participants reporting good SRH showed a non-significant increase from 58 to 63% RR, 95%CI: 1.1 (1.0, 1.2) from baseline to follow-up while mean values of all four QoL domains increased significantly from baseline to follow-up; the physical domain from 13.7 to 15.7 B, 95%CI: 1.9 (1.6, 2.3), the psychological domain from 12.8 to 14.5 B, 95%CI: 1.7 (1.3, 2.0), social relationships from 13.7 to 15.3 B, 95%CI: 1.6 (1.2, 2.0) and the environmental domain from 9.0 to 14.0 5.1 B, 95%CI: (4.7, 5.4). Positive effect modifiers for improvement in SRH and QoL over time include male gender, younger age, low level of social support and illegal status in transit country. Conclusion Our results show that good SRH remain stable while all four QoL domains improve, most pronounced in the environment domain. Understanding the dynamics of migration and health is a fundamental step in reaching health equity.
