Accounting Restatements: Are they Always Bad News for Investors?
This study investigates a large sample of financial statement restatements over the
period 1986-2001, and compares restatements caused by changes in accounting principles
to those caused by errors. Typically, investors perceive restatements as negative signals due to three potential reasons: (i) the restatement indicates problems with the accounting system that may be manifestations of broader operational (and managerial) problems, (ii) the restatement causes downward revisions in future cash flows expectations, and (iii) the restatement indicates managerial attempts to cover up income decline through “cooking
the books”. We provide evidence that market reactions to restatements due to errors are
generally negative. We show that these restatements come in periods of declining profits and lower profits than industry peers for the restating firms, consistent with both
opportunistic managerial behavior and operational problems. However, investors’
reactions to income-increasing restatements due to errors are not different from zero,
suggesting that the perceived failure of the accounting system is just offset by the upward revisions in future cash flow expectations in these cases of income-increasing errors.
Thus, our combined results show that not all restatements are alike; users of the
information need to carefully assess the existence and potential effects of the three factors that typically cause the downward revisions in stock prices on a case by case basis
Towards a greater dialogue on disability between Muslims and Christians
Attitudes to disability and disabled people by Muslims – focusing on attitudes in the Middle East and North Africa - and Christians – focusing on the West (here taken to mean Europe, North America and Australasia) - were examined through a grounded theory literature search, with the study being divided into three phases of reading and analysis. The aims of study were to develop a dialogue on disability between the two cultures, to inform an understanding of the attitudes to disability in the two cultures, and to inform cultural practice in promoting support and equality in both cultures. The study finds that Islam and Christianity have much in common and are a force for good in promoting and developing disability equality in both Muslim and Christian cultures
Screening for distant metastases in patients with ipsilateral breast tumor recurrence: the impact of different imaging modalities on distant recurrence-free interval
Purpose In patients with ipsilateral breast tumor recurrence (IBTR), the detection of distant disease determines whether the
intention of the treatment is curative or palliative. Therefore, adequate preoperative staging is imperative for optimal treatment
planning. The aim of this study is to evaluate the impact of conventional imaging techniques, including chest X-ray and/or
CT thorax-(abdomen), liver ultrasonography(US), and skeletal scintigraphy, on the distant recurrence-free interval (DRFI)
in patients with IBTR, and to compare conventional imaging with 18F-FDG PET-CT or no imaging at all.
Methods This study was exclusively based on the information available at time of diagnoses of IBTR. To adjust for differences in baseline characteristics between the three imaging groups, a propensity score (PS) weighted method was used.
Results Of the 495 patients included in the study, 229 (46.3%) were staged with conventional imaging, 89 patients (19.8%)
were staged with 18F-FDG PET-CT, and in 168 of the patients (33.9%) no imaging was used (N=168). After a follow-up of
approximately 5 years, 14.5% of all patients developed a distant recurrence as frst event after IBTR. After adjusting for the
PS weights, the Cox regression analyses showed that the diferent staging methods had no signifcant impact on the DRFI.
Conclusions This study showed a wide variation in the use of imaging modalities for staging IBTR patients in the Netherlands. After using PS weighting, no statistically signifcant impact of the diferent imaging modalities on DRFI was shown.
Based on these results, it is not possible to recommend staging for distant metastases using 18F-FDG PET-CT over conventional imaging technique
Comparison of outcome and characteristics between 6343 COVID-19 patients and 2256 other community-acquired viral pneumonia patients admitted to Dutch ICUs
Purpose: Describe the differences in characteristics and outcomes between COVID-19 and other viral pneumonia patients admitted to Dutch ICUs. Materials and methods: Data from the National-Intensive-Care-Evaluation-registry of COVID-19 patients admitted between February 15th and January 1th 2021 and other viral pneumonia patients admitted between January 1st 2017 and January 1st 2020 were used. Patients' characteristics, the unadjusted, and adjusted in-hospital mortality were compared. Results: 6343 COVID-19 and 2256 other viral pneumonia patients from 79 ICUs were included. The COVID-19 patients included more male (71.3 vs 49.8%), had a higher Body-Mass-Index (28.1 vs 25.5), less comorbidities (42.2 vs 72.7%), and a prolonged hospital length of stay (19 vs 9 days). The COVID-19 patients had a significantly higher crude in-hospital mortality rate (Odds ratio (OR) = 1.80), after adjustment for patient characteristics and ICU occupancy rate the OR was respectively 3.62 and 3.58. Conclusion: Higher mortality among COVID-19 patients could not be explained by patient characteristics and higher ICU occupancy rates, indicating that COVID-19 is more severe compared to other viral pneumonia. Our findings confirm earlier warnings of a high need of ICU capacity and high mortality rates among relatively healthy COVID-19 patients as this may lead to a higher mental workload for the staff.

Variation in neurosurgical management of traumatic brain injury
Background: Neurosurgical management of traumatic brain injury (TBI) is challenging, with only low-quality evidence. We aimed to explore differences in neurosurgical strategies for TBI across Europe. Methods: A survey was sent to 68 centers participating in the Collaborative European Neurotrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) study. The questionnaire contained 21 questions, including the decision when to operate (or not) on traumatic acute subdural hematoma (ASDH) and intracerebral hematoma (ICH), and when to perform a decompressive craniectomy (DC) in raised intracranial pressure (ICP). Results: The survey was completed by 68 centers (100%). On average, 10 neurosurgeons work in each trauma center. In all centers, a neurosurgeon was available within 30Â min. Forty percent of responders reported a thickness or volume threshold for evacuation of an ASDH. Most responders (78%) decide on a primary DC in evacuating an ASDH during the operation, when swelling is present. For ICH, 3% would perform an evacuation directly to prevent secondary deterioration and 66% only in case of clinical deterioration. Most respondents (91%) reported to consider a DC for refractory high ICP. The reported cut-off ICP for DC in refractory high ICP, however, differed: 60% uses 25Â mmHg, 18% 30Â mmHg, and 17% 20Â mmHg. Treatment strategies varied substantially between regions, specifically for the threshold for ASDH surgery and DC for refractory raised ICP. Also within center variation was present: 31% reported variation within the hospital for inserting an ICP monitor and 43% for evacuating mass lesions. Conclusion: Despite a homogeneous organization, considerable practice variation exists of neurosurgical strategies for TBI in Europe. These results provide an incentive for comparative effectiveness research to determine elements of effective neurosurgical care

[Lung cancer in the Netherlands in the period 1989-1997: the epidemic is not over yet]
OBJECTIVE: To describe and interpret changes in incidence, mortality and survival of lung cancer in the Netherlands in the period 1989-1997. DESIGN: Secondary data analysis. METHODS: Data on the incidence of lung cancer were collected from the Dutch Cancer Registration (1989-1997), on mortality from Statistics Netherlands (CBS; 1989-1994), on the incidence of lung cancer in other European countries from EUROCIM (1990-1994), on survival of Dutch lung cancer patients from the Comprehensive Cancer Centre Amsterdam (1988-1997) and the Comprehensive Cancer Centre South (1988-1992) and on survival of other European lung cancer patients from EUROCARE (1985-1989). Incidence rates were calculated per 100,000 person years and standardized by age according to the European population structure. Survival was calculated as the ratio of observed survival among the lung cancer patients and the expected survival of the general population. RESULTS: The incidence of lung cancer among men decreased from 109 to 93, whereas that among women increased from 18 to 23. The incidence of lung cancer among Dutch men was high in comparison to other European countries, whereas that among women was average. The trends in lung cancer incidence were probably related to the trends in past smoking behaviour. Mortality decreased among men from 106 to 91 and increased among women from 15 to 20. Survival was better for younger patients, a localised tumour, and better for squamous cell carcinoma or adenocarcinoma than for large-cell undifferentiated or small-cell carcinoma. The relative 5-year survival was 12%, the relative 1-year survival 39%; these were good in comparison with other European countries. CONCLUSION: The incidence and mortality of lung cancer among Dutch men decreased, but still in 1997 almost 20 men in the Netherlands died each day of lung cancer. Among women the end of the increase is not in sight and in 1997 over 5 women died each day of lung cancer
