Artificial Intelligence in Lung Cancer Imaging: From Data to Therapy.

Lung cancer remains a global health challenge, leading to substantial morbidity and mortality. While prevention and early detection strategies have improved, the need for precise diagnosis, prognosis, and treatment remains crucial. In this comprehensive review article, we explore the role of artificial intelligence (AI) in reshaping the management of lung cancer.

Deep Learning-Based Versus Iterative Image Reconstruction for Unenhanced Brain CT: A Quantitative Comparison of Image Quality.

This exploratory retrospective study aims to quantitatively compare the image quality of unenhanced brain computed tomography (CT) reconstructed with an iterative (AIDR-3D) and a deep learning-based (AiCE) reconstruction algorithm. After a preliminary phantom study, AIDR-3D and AiCE reconstructions (0.5 mm thickness) of 100 consecutive brain CTs acquired in the emergency setting on the same 320-detector row CT scanner were retrospectively analyzed, calculating image noise reduction attributable to the AiCE algorithm, artifact indexes in the posterior cranial fossa, and contrast-to-noise ratios (CNRs) at the cortical and thalamic levels.

The novel loss of function Ile354Val mutation in PPARG causes familial partial lipodystrophy.

Aims: Familial partial lipodystrophy (FPLD) is a rare autosomal dominant disorder, mostly due to mutations in lamin A (LMNA) or in peroxisome proliferator-activated receptor gamma (PPARG) genes. In the present study, we aimed to identify and functionally characterize the genetic defect underlying FPLD in an Italian family presenting with several affected individuals in three consecutive generations.

Methods: Mutational screening by direct Sanger sequencing has been carried out on both LMNA and PPARG genes.

Short-term efficacy of high intensity group and individual education in patients with type 2 diabetes: a randomized single-center trial.

Purpose: The aim of this randomized study was to examine the efficacy of two high intensity educational programs: the conversation maps-based (CM™) education and the individual education (IE), compared to usual care (UC) in a cohort of type 2 diabetic (T2DM) patients.

Methods: Ninety T2DM outpatients (30 per group) were randomized and 79 finished the study and were analyzed. The CM™ and IE groups received four educational sessions at 0, 4, 8 and 12 weeks, while the UC group received two brief individual sessions at 0 and 12 weeks.

IRIS: methodological assessment of psychopathological disease in a cohort of hirsute women.

Background: Hirsutism in females can be a source of considerable psychological distress and a threat to female identity. The aim of our study was to evaluate a possible relationship between facial, total body hair involvement and physical, mental and social well-being during 12 months of follow-up and treatment. Both objective and subjective methods of evaluating hirsutism were used: the Ferriman-Gallwey (FG) scoring method and the questionnaires General Health Questionnaire (GHQ)-12, Polycystic Ovary Syndrome Questionnaire (PCOSQ) and SF-12.

Very severely obese patients have a high prevalence of type 2 diabetes mellitus and cardiovascular disease.

The prevalence of very severe obesity has increased progressively and faster than other classes of obesity over the last years. It is unclear whether the prevalence of obesity-related complications and health risks increases progressively or reaches a plateau above a certain degree of obesity. The aim of our study was to investigate whether the severity of obesity was correlated with the prevalence of type 2 diabetes mellitus (T2DM), impaired fasting glucose, impaired glucose tolerance (IGT), metabolic syndrome (MS), and cardiovascular diseases (CVDs) in a large cohort of patients with different degrees of obesity.

Prevalence of osteoporosis and vertebral fractures in acromegalic patients.

Growth Hormone (GH) and Insulin-like Growth Factor (IGF-1) stimulate proliferation, differentiation and extracellular matrix production in osteoblastic cells. GH and IGF-1 also stimulate recruitment and bone resorption activity in osteoclastic cells. A chronic systemic GH and IGF-1 excess produces an increased bone turn over in acromegalic patients (pts).

Lamin A/C gene: sex-determined expression of mutations in Dunnigan-type familial partial lipodystrophy and absence of coding mutations in congenital and acquired generalized lipoatrophy.

Missense mutations of the lamin A/C gene, LMNA, have been recently identified in Dunnigan-type familial partial lipodystrophy (FPLD), which belongs to a heterogeneous group of rare disorders affecting adipose tissue distribution and metabolism. In this study, we sequenced the LMNA coding region from patients presenting with FPLD or other forms of lipodystrophy. We identified two heterozygous mutations in exon 8, R482W and R482Q, in FPLD patients (six families and one individual) with various clinical presentations.

Clinical features and hormonal characteristics in a case of ovarian arrhenoblastoma.

We report a case of a 34-year-old woman affected with ovarian arrhenoblastoma characterized by very high testosterone (T) levels (34.0-60.0 ng/ml; n.

Pubarche induction with testosterone treatment in women with panhypopituitarism.

Objective: To evaluate the efficacy and safety of T therapy in the induction of pubic hair growth in women with congenital panhypopituitarism.

Design: Prospective clinical study.

Setting: Patients followed at the University Endocrinology Clinic.

Relation between steroid receptor status and body weight in breast cancer patients.

Obesity is known to adversely affect breast cancer prognosis. Since obesity is associated with increased oestrogen levels, and oestrogens are growth stimulators of oestrogen receptor (ER)-positive breast carcinomas, we evaluated the relationship between the ER and progesterone receptor (PR) status of the neoplastic tissue and obesity in a series of 615 breast cancer patients. Both ER and PR concentrations were significantly and positively correlated with obesity by multiple regression analysis.

Hypergonadotropinemia not associated to ovarian failure and induced by factors interfering in radioimmunoassay.

Unexpectedly high LH and FSH serum levels, measured by conventional RIA methods employing a rabbit antibody, were observed in eight women 18 to 34 years of age who came to our observation for acne and/or hirsutism and with no sign of premature ovarian failure. Reinvestigation of patient histories revealed that all of them had previously received multiple injections of a multimicrobial vaccine containing rabbit proteins. Luteinizing hormone and FSH were remeasured by IRMA and ELISA.

Ovulation monitored by serum 17 beta-estradiol and ultrasound: differential ovarian response to human gonadotropins in various anovulatory states.

Ovulation induction with human gonadotropins (hMG or pFSH and hCG) was simultaneously monitored with daily serum 17 beta-estradiol measurements and ultrasound in 38 infertile women. They were subgrouped as follows: A, hypogonadotropic hypogonadism (n. 7); B, polycystic ovary syndrome (n.

X-ray structure determination of mexiprostil, a new gastroprotective 16-methoxy-16-methyl-PGE1 analogue.

Mexiprostil is a new gastroprotective 16-methoxy-16-methyl-PGE1 methyl ester. To assign the absolute configuration at C-15, a crystalline high-melting C-1 ester analog 5 11,15-dihydroxy-16-methoxy-16-methyl-9-oxoprost-13-en-1-oic acid 4-(4-bromobenzamide)phenyl ester (15R, 16R) was prepared and submitted to single crystal X-ray analysis. Since C-8, C-11, C-12 and C-16 are shown to have R configurations, the X-ray diffraction results established that the configuration at C-15 is also R.

Influence of abstinence length on ejaculate characteristics.

In order to study the influence of sexual abstinence on sperm concentration and semen volume, we have evaluated 195 semen samples of healthy individuals, grouped as follows according to abstinence length: A) 2-4 days; B) 5-7 days; C) more than 7 days. Differences between semen samples collected at home or at the laboratory were also studied. Semen volume was smaller in group A than in group B and C (p less than 0.

The frequency of cold thyroid nodules and thyroid malignancies in patients from an iodine-deficient area.

An analysis of thyroid cancer morbidity was carried out in two adjacent areas of Sicily differing in iodine intake. A consecutive series of 911 patients with "cold" nodules from an iodine-deficient area (IDA) and 2537 from a control area (CA) were examined by fine needle aspiration and selected for surgery and pathologic examination. Malignancies were found in 27 of the patients (2.

Structure-activity studies of 16-methoxy-16-methyl prostaglandins.

The synthesis of the pure diastereoisomer of 16-methoxy-16-methyl-PGF2 alpha, -PGE2, and -PGE1 is described. The absolute configuration of C-16 was established by chemical methods, while the absolute C-15 configurations of the diastereoisomers were assigned tentatively on the basis of their chromatographic behavior and NMR spectra. The synthetic prostaglandin analogues were evaluated for antisecretory, antifertility, and diarrheogenic effects.

Angiotensin converting enzyme inhibitors as antihypertensive agents: 1-[(2-mercaptocycloalkyl)carbonyl]-L-prolines.

The synthesis of 1-[(2-mercaptocyclopentyl)carbonyl]-L-prolines, 1-[(2-mercaptocyclobutyl)carbonyl]-L-prolines and related benzoyl derivatives as pure isomers is described. The abilities of all the compounds to inhibit angiotensin converting enzyme (ACE) in vitro and in vivo and to lower the systolic blood pressure in renal hypertensive dogs were determined. Three of them, namely 1-[[2-(benzoylthio)cyclopentyl]carbonyl]-L-proline (10f(R,S], 1-[(2-mercaptocyclopentyl)carbonyl]-L-proline (10g(R,S], and 1-[[2-(benzoylthio)cyclobutyl]carbonyl]-L-proline (16f(R,S], were found to be as potent as captopril in reducing blood pressure.

Reproductive hormone studies in three subjects with a Robertsonian translocation.

The reproductive hormone function was investigated in three subjects, two brothers and one unrelated patient, with a Robertsonian translocation, who had come to us because of infertility. Basal levels of LH, FSH, testosterone, 17-beta-estradiol and prolactin were repeatedly measured by radioimmunoassays. In addition, clomiphene citrate, synthetic LH-RH, hCG and TRH tests were carried out.
