Alignment of the CMS muon system with cosmic-ray and beam-halo muons

This is the Pre-print version of the Article. The official published version of the Paper can be accessed from the link below - Copyright @ 2010 IOPThe CMS muon system has been aligned using cosmic-ray muons collected in 2008 and beam-halo muons from the 2008 LHC circulating beam tests. After alignment, the resolution of the most sensitive coordinate is 80 microns for the relative positions of superlayers in the same barrel chamber and 270 microns for the relative positions of endcap chambers in the same ring structure. The resolution on the position of the central barrel chambers relative to the tracker is comprised between two extreme estimates, 200 and 700 microns, provided by two complementary studies. With minor modifications, the alignment procedures can be applied using muons from LHC collisions, leading to additional significant improvements.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR(Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTDS (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)

Reducing neonatal infections in south and south central Vietnam : the views of healthcare providers

Background: Infection causes neonatal mortality in both high and low income countries. While simple interventions to prevent neonatal infection are available, they are often poorly understood and implemented by clinicians. A basic understanding of healthcare providers' perceptions of infection control provides a platform for improving current practices. Our aim was to explore the views of healthcare providers in provincial hospitals in south and south central Vietnam to inform the design of programmes to improve neonatal infection prevention and control. Methods: All fifty-four participants who attended a workshop on infection prevention and control were asked to complete an anonymous, written questionnaire identifying their priorities for improving neonatal infection prevention and control in provincial hospitals in south and south central Vietnam. Results: Hand washing, exclusive breastfeeding and safe disposal of medical waste were nominated by most participants as priorities for preventing neonatal infections. Education through instructional posters and written guidelines, family contact, kangaroo-mother-care, limitation of invasive procedures and screening for maternal GBS infection were advocated by a smaller proportion of participants. Conclusions: The opinions of neonatal healthcare providers at the workshop accurately reflect some of the current international recommendations for infection prevention. However, other important recommendations were not commonly identified by participants and need to be reinforced. Our results will be used to design interventions to improve infection prevention in Vietnam, and may be relevant to other low-resource countries.8 page(s

Equipment for neonatal resuscitation in a middle-income country : a national survey in Vietnam

Background: Interventions to improve neonatal resuscitation are considered a priority for reducing neonatal mortality. In addition to training programs for health caregivers, the availability of adequate equipment in all delivery settings is crucial. In this study, we assessed the availability of equipment for neonatal resuscitation in a large sample of delivery rooms in Vietnam, exploring regional differences. Methods: In 2012, a structured questionnaire on 2011 neonatal resuscitation practice was sent to the heads of 187 health facilities, representing the three levels of hospital-based maternity services in eight administrative regions in Vietnam, allowing national and regional estimates to be calculated. Results: Overall the response rate was an 85.7 % (160/187 hospitals). There was a limited availability of equipment considered as "essential" in the surveyed centres: stethoscopes (68.0 %; 95 % CI: 60.3–75.7), clock (50.3 %; 42.0–58.7), clothes (29.5 %; (22.0–36.9), head covering (12.3 %; 7.2–17.4). The percentage of centres equipped with polyethylene bags (2.2 %; 0.0–4.6), pulse oximeter (9.4 %; 5.2–13.6) and room air source (1.9 %; 0.1–3.6) was very low. Conclusion: Adequate equipment for neonatal resuscitation was not available in a considerable proportion of hospitals in Vietnam. This problem was more relevant in some regions. The assessment strategy used in this study could be useful for organizing the procurement and distribution of supplies and equipment in other low and/or middle resource settings.8 page(s

Neonatal resuscitation in Vietnam : a national survey of a middle-income country

Aim: Interventions that improve neonatal resuscitation are critical if we are to reduce perinatal mortality. We evaluated the consistency of resuscitation practices, and adherence to the international guidelines for neonatal resuscitation, in a large representative sample of hospitals in Vietnam. Methods: A questionnaire was sent to 187 public central, provincial and district hospitals, representing the three levels of public hospital-based maternity services in Vietnam. Results: The overall response rate was 85.7% (160/187 hospitals), and the response rate was 100%, 90.3% and 81.7% for central, provincial and district hospitals, respectively. There were 620 300 births in the surveyed hospitals during the year 2011, representing almost half of all inpatient births in Vietnam. Neonatal resuscitation was provided by obstetricians and, or, midwives at all levels. Half of the hospitals did not follow recommendations for delaying cord clamping. The majority of the hospitals did not have a wall thermometer in the delivery room (80.5%) and did not monitor neonatal temperature after birth (64.1%). A large proportion of hospitals (39.9%) used 100% oxygen to initiate resuscitation and only central hospitals avoided this practice. Conclusion: Our survey identified significant variations in resuscitation practices between central, provincial and district hospitals and limited adherence to international recommendations.8 page(s
