The CMS groups of rats were housed separately in different cage in the duration of the CMS procedures, and 5 animals per cage were housed for the control group rats.
In rats, application of chronic mild stress (CMS) procedures resulted in a variety of behavioural, neurochemical, neuroendocrine and neuroimmune alterations resembling some of the dysfunctions observed in human depression [9] [16].
Generally, these findings are interpreted as either being due to blunted emotionality [52] or caused by methodological differences [48] of CMS procedures that yield a 'classic' anxiogenic stress response.
Procedures were identified based on the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) procedures and current procedural terminology codes; Table S1 lists ICD-9 codes.
Medical claims include diagnosis codes recorded with International Classification of Disease, Ninth Edition, Clinical Modification (ICD-9-CM), procedures recorded with ICD-9 procedure codes, current procedural terminology (CPT) codes, or healthcare common procedure coding system, and revenue codes.
For cocaine use disorders (CUD), specifically, the most potent intervention currently available for initiating abstinence is behavior therapy using contingency management (CM) procedures, with early cessation being a robust predictor of future abstinence.
ICD-9-CM procedures were assigned, using a tool developed by the Agency for Healthcare Research and Quality [ 19], to one of four categories: minor diagnostic, minor therapeutic, major diagnostic and major therapeutic.
They report up to 15 International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes for diagnoses and up to fifteen ICD-9-CM procedures codes, date of service, place of service, provider type, and plan and patient paid amounts.
The distribution of elective procedures identified as feasible in day care is shown in Table 5 (ICD-9-CM procedures were grouped in intervention types); these were mostly endovascular heart operations, which in Switzerland are often performed in an inpatient setting.
Primary and secondary International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) procedure codes and Current Procedural Terminology, Fourth Edition (CPT-4) codes in the claims data used to identify mastectomy and BCS/LND were based on the work by Nattinger et al. [15].
Only individuals who had an inpatient stay associated with THA (ICD-9-CM procedure code 81.51 or Current Procedural Terminology codes 27130 and 27132) between January 1, 2006 and September 30, 2009 were identified.
