Hungry bone syndrome can occur after parathyroidectomy which is performed due to primary hyperparathyroidism. Hungry bone syndrome is characterized by showing postoperative hypocalcemia which is caused by the remineralization of various minerals, including calcium inside the bone. This syndrome requires a long term supplementation of calcium. Identifying the preoperative predictors of hypocalcemia is essential and important for postoperative management. From here on in, we report two cases of patients with parathyroid adenoma who have undergone parathyroidectomy. We would like to report and discuss the management of hungry bone syndrome experienced from the two cases that have been mentioned above. We report these two cases with a review of the literature.

Despite long-term research achievements, the development of cell therapy (CT) products remains challenging. This is because the risks experienced by the subject and therapeutic effects in the clinical trial stage are unclear due to the various uncertainties of CT when administered to humans. Nevertheless, as autologous cell products for systemic administration have recently been approved for marketing, CT product development is accelerating, particularly in the field of unmet medical needs. The human experience of CT remains insufficient compared with other classes of pharmaceuticals, while there are countless products for clinical development. Therefore, for many sponsors, understanding the rationale of human application of an investigational product based on the consensus and improving the ability to apply it appropriately for CT are necessary. Thus, defining the level of evidence for safety and efficacy fundamentally required for initiating the clinical development and preparing it using a reliable method for CT. Furthermore, the expertise should be strengthened in the design of the first-in-human trial, such as the starting dose and dose-escalation plan, based on a sufficiently acceptable rationale. Cultivating development professionals with these skills will increase the opportunity for more candidates to enter the clinical development phase.

BACKGROUND: This study provides up-to-date survival data on cardiac resuscitation in adult in-patients. The main objectives of the study were to evaluate the incidence, causes, and outcomes of perioperative cardiac arrest. Objective data might encourage more meaningful attitude in anesthesiologists, surgeons, and patients. METHODS: We retrospectively reviewed patients who experienced perioperative cardiac arrest while receiving noncardiac surgery between January 2004 and December 2012. Collected data included patient characteristics, preoperative evaluations, American Society of Anesthesiologists Physical Status (ASA PS) classification, surgical status (e.g., elective or emergency), type of surgery, and outcomes. RESULTS: We identified 30 cases of perioperative cardiac arrest that occurred in 457,529 anesthetized patients (incidence = 0.66 per 10,000 anesthetized patient; all-cause mortality = 0.21 per 10,000 anesthetic cases). Two-thirds of patients (19 of 30) were emergency cases (21% survival rate; 4 of 19 patients). Most cardiac arrest patients (60%; 18 of 30 patients) were ASA PS IV-V, and only 40% patients were ASA PS I, II and III. Four cases were associated with anesthesia and the patient recovered, and 3 patients recovered after resuscitation. The main causes of cardiac arrest were respiratory- (75%) and medication-related events (25%). CONCLUSIONS: In accordance with anesthetic management guidelines and the development of anesthetic agents, anesthesia-related cardiac arrests decreased in terms of incidence and mortality. However, we recommend that clinicians cautiously keep in mind airway management and the administration of medications, which are important preventative factors.

Objective:
Despite a high prevalence of dementia in older adults hospitalized with severe acute respiratory syndrome coronavirus 2 infection (SARS-CoV-2), or so called COVID-19, research investigating association between preexisting diagnoses of dementia and prognosis of COVID-19 is scarce. We aimed to investigate treatment outcome of patients with dementia after COVID-19.
Methods:
We explored a nationwide cohort with a total of 2,800 subjects older than 50 years who were diagnosed with COVID-19 between January and April 2020. Among them, 223 patients had underlying dementia (dementia group). We matched 1:1 for each dementia- non-dementia group pair yielding 223 patients without dementia (no dementia group) using propensity score matching.
Results:
Mortality rate after COVID-19 was higher in dementia group than in no dementia group (33.6% vs. 20.2%, p=0.002). Dementia group had higher proportion of patients requiring invasive ventilatory support than no dementia group (34.1% vs. 22.0%, p=0.006). Multivariable analysis showed that dementia group had a higher risk of mortality than no dementia group (odds ratio=3.05, p<0.001). We also found that patients in dementia group had a higher risk of needing invasive ventilatory support than those in no dementia group.
Conclusion
Our results suggest that system including strengthen quarantines are required for patients with dementia during the COVID- 19 pandemic.

Objective:
No previous study examined impact of dementia in the outcome of allogeneic hematopoietic stem cell transplantation (HSCT). We aimed to investigate overall survival (OS) of patients with dementia after receiving HSCT.
Methods:
Among 8,230 patients who underwent HSCT between 2002 and 2018, 5,533 patients younger than 50 years were first excluded. Remaining patients were divided into those who were and were not diagnosed with dementia before HSCT (dementia group: n = 31; no dementia: n = 2,666). Thereafter, among 2,666 participants without dementia, 93 patients were selected via propensity-matched score as non-dementia group. Patients were followed from the day they received HSCT to the occurrence of death or the last follow-up day (December 31, 2018), whichever came first.
Results:
With median follow-up of 621 days for dementia group and 654 days for non-dementia group, 2 year-OS of dementia group was lower than that of non-dementia group (53.3% [95% confidence interval, 95% CI, 59.0−80.2%] vs. 68.8% [95% CI, 38.0−68.2%], p = 0.076). In multivariate analysis, dementia had significant impacts on OS (hazard risk = 2.539, 95% CI, 1.166−4.771, p = 0.017).
Conclusion
Our results indicated that patients diagnosed with dementia before HSCT have 2.539 times higher risk of mortality after transplantation than those not having dementia. With number of elderly needing HSCT is increasing, further work to establish treatment guidelines for the management of HSCT in people with dementia is needed.
