Osteoporosis affects approximately one in five European women and leads to fragility fractures, which result in poor health, social and economic consequences. Fragility fractures are a strong risk factor for subsequent major osteoporotic fracture (MOF), with risk of MOF being elevated in the 1-2 years following an earlier fracture, a concept described as "imminent risk". This study examines risk of subsequent MOF in patients with one, two or three prior fractures by age and type of fracture. In this retrospective, observational cohort study, Swedish women aged ≥50 years with ≥1 any clinical fragility fracture between July 1, 2006 and December 31, 2012 were identified from Sweden's National Patient Register. Each patient was age- and sex-matched to three controls without history of fracture. Group 1 women included those with one fragility fracture during the study period; Group 2 included those with two fragility fractures; and Group 3 included those with three fragility fractures. "Index fracture" was defined as the first fracture during the study period for Group 1; the second for Group 2; and the third for Group 3. Patients in each cohort and matched controls were followed for up to 60 months or until subsequent MOF (hip, vertebra, forearm, humerus), death or end of data availability. 231,769 women with at least one fracture were included in the study and therefore constituted Group 1; of these, 39,524 constituted Group 2 and of those, 7656 constituted Group 3. At five years, cumulative incidence of subsequent MOF was higher in patients with a history of fracture as compared to controls (Group 1: 20.7% vs 12.3%; Group 2: 32.0% vs 15.3%). Three-year cumulative incidence for Group 3 was 12.1% (vs 10.7% for controls). After adjusting for baseline covariates, risk of subsequent MOF was highest within 0-24 months following an index fracture, then decreased but remained elevated as compared to controls. Having two prior fractures, vertebral fractures and younger age at time of index fracture were associated with greater relative risk. Women with a history of osteoporotic fracture are at increased risk of subsequent fracture, which is highest during the first 24 months following a fracture. Younger women and those with vertebral fractures are at greatest relative risk, suggesting that treatment should target these patients and be timely enough to impact the period of imminent risk.

Background: Dendritic cells (DCs) isolated from tumor bearing animals or from individuals with solid tumors display functional abnormalities and the DC impairment has emerged as one mechanism for tumor evasion from the control of the immune system. Ductal pancreatic adenocarcinoma (PDAC), the most common pancreatic cancer, is recognized as a very aggressive cancer type with a mortality that almost matches the rate of incidence. Methods: We examined the systemic influence ductal pancreatic adenocarcinoma (PDAC) exerted on levels of peripheral blood DCs and inflammatory mediators in comparison to the effects exerted by other pancreatic tumors, chronic pancreatitis, and age-matched controls. Results: All groups examined, including PDAC, had decreased levels of myeloid DCs (MDC) and plasmacytoid DCs (PDC) and enhanced apoptosis in these cells as compared to controls. We found elevated levels of PGE2 and CXCL8 in subjects with PDAC, and chronic pancreatitis. Levels of these inflammatory factors were in part restored in PDAC after tumor resection, whereas the levels of DCs were impaired in the majority of these patients ~12 weeks after tumor removal. Our results prove that solid pancreatic tumors, including PDAC, systemically affect blood DCs. The impairments do not seem to be tumor-specific, since similar results were obtained in subjects with chronic pancreatitis. Furthermore, we found that PDAC patients with a survival over 2 years had significant higher levels of blood DCs compared to patients with less than one year survival. Conclusions: Our findings points to the involvement of inflammation in the destruction of the blood MDCs and PDCs. Furthermore, the preservation of the blood DCs compartment in PDAC patients seems to benefit their ability to control the disease and survival.

Summary We studied effectiveness of osteoporosis treatment in women older than 80 years, who often are not included in clinical trials. Treatments were as effective on bone density and fractures as in younger women. Introduction To study real-world effectiveness of osteoporosis treatment on BMD and fractures in the oldest old women (≥ 80 years) compared with women (60–79 years) in the clinical setting using Swedish health register data. Methods National registers and data from DXA machines were used to study effectiveness of all available osteoporosis treatments in women 60–79 and ≥ 80 years using three approaches: (1) Total Hip BMD change up to 8 years after treatment start; (2) fracture incidence where patients served as their own controls, comparing the first 3 months after treatment start with the subsequent 12 months; and (3) comparison of fracture incidence post-fracture in women ≥ 80 years treated with osteoporosis treatment or calcium/vitamin D. Results Analysis 1: Total Hip BMD increased by up to 6.7% and 7.7% in women 60–79 and ≥ 80 years old, respectively. The mean increase in BMD was 1.1%-units per year in both age groups. Analysis 2: Relative to the 3-month baseline, fracture incidence decreased during the subsequent 12 months of treatment. Incidence rate ratios were estimated at 0.65, 0.74, 0.29, and 0.81 for any, hip, vertebral, and non-hip-non-vertebral fracture, respectively. Analysis 3: A 24-month incidence of any fracture in women ≥ 80 years given post-fracture osteoporosis treatment was lower (HR = 0.78) than in women given calcium/vitamin D, but treatment allocation was not random, with lower mortality (HR = 0.51) in patients receiving OP treatment. Conclusions Osteoporosis medication in women > 80 years in clinical practice likely works, and the magnitude of effect is similar to what was estimated in younger women. The choice between osteoporosis treatment and calcium/vitamin D after fracture in women ≥ 80 years is not random but appears associated with the patient’s health status and presence of vertebral fractures, rather than the known risk profile of sustaining a fracture at a high age.

Purpose: To investigate the prevalence, activity limitations and potential risk factors of upper extremity impairments in type 1 diabetes in comparison to controls. Methods: In a cross-sectional population-based study in the southeast of Sweden, patients with type 1 diabetes <35 years at onset, duration ≥20 years, <67 years old and matched controls were invited to answer a questionnaire on upper extremity impairments and activity limitations and to take blood samples. Results: Seven hundred and seventy-three patients (ages 50 ± 10 years, diabetes duration 35 ± 10 years) and 708 controls (ages 54 ± 9 years) were included. Shoulder pain and stiffness, hand paraesthesia and finger impairments were common in patients with a prevalence of 28–48%, which was 2–4-folds higher than in controls. Compared to controls, the patients had more bilateral impairments, often had coexistence of several upper extremity impairments, and in the presence of impairments, reported more pronounced activity limitations. Female gender (1.72 (1.066–2.272), p = 0.014), longer duration (1.046 (1.015–1.077), p = 0.003), higher body mass index (1.08 (1.017–1.147), p = 0.013) and HbA1c (1.029 (1.008–1.05), p = 0.007) were associated with upper extremity impairments. Conclusions: Compared to controls, patients with type 1 diabetes have a high prevalence of upper extremity impairments, often bilateral, which are strongly associated with activity limitations. Recognising these in clinical practise is crucial, and improved preventative, therapeutic and rehabilitative interventions are needed.

Summary We assessed the prevalence of hypocalcemia after denosumab injections in a real-world cohort routinely monitored for calcium during up to 7.5 years of treatment. Among 1096 injections in 242 patients, 6.3% resulted in hypocalcemia, and was independent of the injection number. Severe hypocalcemia was rare (1%). Purpose To assess the prevalence of and risk factors for hypocalcemia after administration of denosumab in a patient cohort routinely monitored for ionized calcium after each dose. Methods In this retrospective observational study, we analyzed denosumab-induced hypocalcemia in a real-world cohort who were routinely followed up with ionized calcium pre- and post-injection (within 31 days after injection) during the period 2011 to 2020. Results In total, we included data from 1096 denosumab injections in 242 individuals (1–15 injections per patient). The mean age for the first injection was 74 ± 10 years, and 88% were female. Post-injection hypocalcemia occurred after 6.3% of all injections (4.6% mild, 0.6% moderate, and 1.1% severe) and was independent of the number of injections (rate of hypocalcemia varied from 3–8%). Risk factors for hypocalcemia were male sex, severe renal failure, pre-injection hypocalcemia, hypomagnesemia, hypophosphatemia, and vitamin D insufficiency. Furthermore, older age was not associated with an increased hypocalcemia risk. Conclusions Denosumab-induced hypocalcemia is a prevalent adverse event, which occurs independently of the number of injections. However, severe hypocalcemia is a rare occurrence, and severe renal failure and nutritional status appear to be important predictive factors. Magnesium and phosphate might add value in the pre-injection risk assessment; however, this observation needs to be confirmed in larger cohorts.
