    Functional cystic lesion of the parathyroid gland is a rare cause of primary hyperparathyroidism (PHPT). Caspofungin They have been postulated to arise from the hemorrhage and cystic degeneration in the parathyroid adenoma (PA). We intended to analyze their scintigraphic and histopathological findings since available literature is sparse.

    Dual-phase

    Tc-sestamibi planar and SPECT/CT scans performed from January 2014 to January 2020 in patients presenting with PHPT were retrospectively analyzed. The clinical, biochemical, and ultrasound features were collected. Planar and SPECT/CT imaging parameters were analyzed. Detailed histopathological analysis, along with post-surgical clinical and biochemical features of the patients who underwent surgery, was reviewed with a mean follow-up of 21.8 ± 20.1 months.

    Of the 979 scans analyzed, 10 showed cystic parathyroid lesions (MF- 37, mean age 45.6 ± 15 years, range 23-66). The predominant presenting features in patients were abdominal pain and renal stone disease, present in 60% of the patients. On planar scintigraphy, 90% of the patients had tracer avid distinct lesions, whereas tracer activity was seen in the solid part of the cystic lesions in all 10 patients on SPECT/CT, with cystic areas showing an attenuation of 23.1 ± 7.6 HU. Eight of these patients underwent surgery, with all showing PA with cystic changes on histopathology. Two of these patients also showed hemorrhage within the cystic spaces.

    Hemorrhage within a PA may give rise to cystic parathyroid lesions with PHPT.

    Tc-sestamibi scintigraphy with dual-phase imaging and SPECT/CT may help in detecting this rare entity.

    The American Joint Committee on Cancer tumor node metastasis (TNM) staging system eighth edition (TNM-8) for differentiated thyroid cancer (DTC) has been introduced as a replacement for tumor node metastasis staging system seventh edition (TNM-7). We present the first study from a Middle Eastern population comparing these 2 versions of the TNM staging system.

    We compared TNM-8 with TNM-7 in 701 patients with DTC seen during a 3-year period with a median age of 37 years (6-83) and a female-to-male ratio of 558 (79.6%) to 143 (20.4%).

    The number (%) of patients within each stage in TNM-7 and TNM-8, respectively, are as follows stage I= 503 (71.6%) and 583 (83.2%), stage II= 52 (7.4%) and 81 (11.4%), stage III= 53 (7.6%) and 6 (0.9%), and stage IV= 93 (13.2%) and 31 (4.6%). Overall, 172 patients (24.5%) were downstaged in TNM-8 compared to that in TNM-7, as follows 26, 30, and 24 patients from stages II, III, and IV in TNM-7 to stage I in TNM-8; 23 and 32 patients from TNM-7 stages III and IV to TNM-8 stage II; 6 patients from stage IVa in TNM-7 to stage III in TNM-8; and 31 patients from stage IVc in TNM-7 to stage IVb in TNM-8. TNM-7 and TNM-8 predicted the long-term outcome well (median follow-up, 7.9 years), but Kaplan-Meier analysis showed better separation of cancer-specific survival in TNM-8 compared to TNM-7.

    Compared with TNM-7, TNM-8 approximately downstaged a quarter of DTC patients and was more robust in separating the outcome of different stages over time.

    Gestational diabetes mellitus (GDM) is associated with adverse maternal and fetal outcomes. This study aimed to identify early and reliable GDM predictors that would enable implementation of preventive and management measures.

    The participants were a 28-week prospective cohort of invitro fertilization (IVF)-conceived pregnant women (≤39 years, body mass index 18.5-38 kg/m

    ) without a known history of diabetes mellitus. Fasting blood samples were analyzed at baseline (pre-IVF) and 12 weeks’ gestation for reproductive hormones, glucose, serum insulin, lipids, thyroid function, adiponectin, and lipopolysaccharide-binding protein. At 28 weeks, a 75-g oral glucose tolerance test was used to screen for GDM.

    For the overall group at baseline, 22% had BMI ≥30 kg/m

    , 45% had polycystic ovary syndrome, 16% had hemoglobin A1C of 5.7% to 6.1%, and 14% had a past history of GDM. At 28 weeks of gestation (n= 158), 34 women had developed GDM and 124 had not. Significant baseline predictors of GDM onset includeonception maternal BMI, age, and follicle-stimulating hormone/luteinizing hormone ratio are predictors of subsequent development of GDM, early IVF-conceived gestational weight gain is the best predictor of GDM onset.

    Many youth do not use the hybrid closed-loop system for type 1 diabetes effectively. This study evaluated the impact of financial incentives for diabetes-related tasks on use of the 670G hybrid closed-loop system and on glycemia.

    At auto mode initiation and for 16 weeks thereafter, participants received a flat rate for wearing and calibrating the sensor ($1/day), administering at least 3 mealtime insulin boluses per day ($1/day), and uploading ($5/week). Weekly bonuses were given for maintaining at least 70% of the time in auto mode, which were increased for persistent auto mode use from $3/week to a maximum of $13/week. If a participant failed to maintain auto mode for a week, the rewards were reset to baseline. Data from 17 participants aged 15.9 years ± 2.5 years (baseline hemoglobin A1c 8.6% ± 1.1%) were collected at 6, 12, and 16 weeks. The reinforcers were withdrawn at 16 weeks, with a follow-up assessment at 24 weeks.

    With reinforcers, the participants administered an average of at least 3 mealtime insulin boluses per day and wore the sensor over 70% of the time. However, auto mode use waned. HbA1clevels decreased by 0.5% after 6 weeks, and this improvement was maintained at 12 and 16 weeks (P < .05). Upon withdrawal of reinforcers, HbA1c levels increased back to baseline at 24 weeks.

    Compensation for diabetes-related tasks was associated with lower HbA1c levels, consistent administration of mealtime insulin boluses, and sustained sensor use. These results support the potential of financial rewards for improving outcomes in youth with type 1 diabetes.
