Patients with breast carcinoma often develop bone metastases that carry a high risk of complications. A randomized, placebo-controlled trial was conducted to evaluate the efficacy and safety of ibandronate in patients with metastatic bone disease following breast cancer. The primary efficacy end point of the study was the proportion of patients who developed skeletal-related events (SREs, defined as pathologic fracture, spinal cord compression, radiation therapy to bone, change in anti-neoplastic therapy and surgery to bone). Secondary end points included time to first skeletal event, skeletal morbidity rate (events/year) and time to progression of bone lesions. In 150 patients (148 [female symbol] / 2 [male symbol]) with breast carcinoma and bone metastases, treatment with intravenous ibandronate 6 mg over 15 min every 4 weeks for 24 months significantly reduced the proportion of patients who experienced an SRE compared with placebo (36% vs. 48%; P = 0.027). Time to first SRE was also delayed significantly (median 457 vs. 304 days; P = 0.007). Multiple event analysis showed that ibandronate reduced the risk of developing an SRE by 32% (hazard ratio = 0.69; 95% confidence interval 0.42-0.79; P = 0.003). In general, ibandronate was well tolerated with very rare grade 3 or 4 toxicity. In this study, ibandronate was shown to be significantly more effective than placebo as a treatment for metastatic bone disease from breast cancer using multiple end points.

Background The Human Coronavirus Disease 2019 (COVID‐19) is a highly contagious respiratory disorder that may result in acute respiratory distress syndrome. The aim of this review was to investigate the incidence and type of respiratory function abnormalities during the follow‐up of patients who recovered from COVID‐19. Methods A systematic search of MEDLINE was conducted, utilising various term combinations. Studies that assessed any respiratory function parameter during the re‐evaluation of patients who recovered from COVID‐19 and were published as full‐text articles in English are included in this review. Results Amongst 183 articles initially retrieved, 8 fulfilled the criteria and were included in this review; they involved a total of 341 adult patients. Four were retrospective studies, one was a prospective cohort study, one was a randomised control trial and two were case reports/case series. The follow‐up time ranged from 1 month since symptom onset to 3 months after discharge. The most frequent abnormality was reduced lung diffusion for carbon monoxide (DLCO), followed by a restrictive pattern. Other findings are the lack of resting hypoxemia, the reduced respiratory muscle strength and the decreased exercise capacity, although relative data are extremely limited. Conclusion Patients who recovered from COVID‐19 present with abnormal respiratory function at short‐term follow‐up, mainly with reduced lung diffusion and a restrictive pattern. However, results are currently very limited in order safe conclusions to be made, regarding the exact incidence of these abnormalities and whether they may be temporary or permanent.

Background: To date, evidence about sleep disturbances among post-COVID-19 patients is limited. This study aimed to evaluate sleep quality after hospitalization due to SARS-CoV-2 infection. Methods: In-person follow-up was conducted in patients with prior hospitalization due to COVID-19 1(Τ1), 3(Τ2), and 6 (Τ3) months after hospital discharge. Patients were asked to complete questionnaires concerning sleep quality: the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Athens Insomnia Scale (AIS), the Fatigue Severity Scale (FSS), and the Stop-BANG (S-B) questionnaire. Results: In total, 133 patients were enrolled (mean age: 56.0 ± 11.48 years, 59.4% males). The most frequently reported comorbidity was arterial hypertension (29.8% of patients), while 37.4% of patients had no comorbidities. The majority of participants exhibited poor sleep quality (global PSQI ≥ 5) at T1 (84.3%), T2 (75.7%), and T3 (77.4%). Insomnia was observed in 56.5%, 53.5%, and 39.2% of participants, respectively (AIS ≥ 6). An FSS score ≥ 4 was observed in 51.2%, 33.7%, and 29.1% of participants at T1, T2, T3, respectively. Elapsed time was found to be negatively and independently associated with the global PSQI, PSQI C5-Sleep disturbance, PSQI C7-Daytime dysfunctions, FSS, and AIS after adjustment for possible confounders. No significant difference was found between groups with good and poor sleep quality (based on the global PSQI) with respect to gender (p = 0.110), age (p = 0.528), BMI (p = 0.816), smoking status (p = 0.489), hypertension (p = 0.427), severity of disease (p = 0.224), the Charlson Comorbidity Index (p = 0.827), or the length of hospital stay (p = 0.162). Participants with excessive daytime sleepiness (EDS) and patients with severe fatigue (FSS ≥ 4) were significantly younger. Females presented a higher rate of insomnia symptoms (55.7% vs. 44.3%, p < 0.001). Conclusions: Several sleep disturbances were observed after hospital discharge for COVID-19 pneumonia at certain time points; However, the improvement over time was remarkable in most domains of the assessed questionnaires.
