Authors: Elwan Mohammed M , Hagras Sherein M , Kasem Manal A 
Published: July 2018

Purpose: To evaluate the feasibility and outcomes of the sole use of 23g pars plana vitrectomy in cases with diabetic vitreous hemorrhage with vitreoretinal traction. Methods: Prospective interventional case series involving patients between January 2013 and January 2018. All eyes underwent 23g pars plana vitrectomy with internal tamponade. Intraoperative parameters including ancillary instruments, the methods used for hemostasis and complications were all recorded. Postoperative parameters including anatomic success rate, functional success, and postoperative complications were recorded and analyzed. Patients were followed up for at least 12 months. Results: A total of 68 eyes of 66 patients were included. Intraoperative ancillary instruments were required in 5 (7.4%) eyes. None of the cases required the use of chandelier illumination, endodiathermy, or scissors. Mean best-corrected visual acuity improved significantly from LogMAR 1.67 ± 0.63 preoperative to 1.22 ± 0.38 at 1-year follow-up (P = 0.005). Functional success was achieved in 37 (54.4%) eyes at 1-year follow-up. Iatrogenic breaks occurred in 3 (4.4%) eyes, vitreous hemorrhage in 4 (5.9%) eyes, and epiretinal membranes in 3 (4.4%) eyes. Repeated vitrectomy was done in 3 (4.4%) eyes. Conclusion: The 23g vitrectomy probe proved to be a safe, effective, and beneficial single tool that could accomplish the diabetic vitrectomy mission exclusively with minimal aid from other instruments in cases with vitreous hemorrhage associated with vitreoretinal traction.

Published: July 2018

Background: Supportive supervision of infection prevention and control (IPC) practices was one of a range of interventions employed at the county level in the control of the world’s most deadly Ebola virus disease outbreak that affected Liberia during 2013–2016. Methods: Datasets generated from four consecutive assessment visits to 25 health facilities in Maryland County, in Liberia, were analysed. Information on IPC practices was obtained by interview, direct observation and completion of a standardised assessment tool. For each of the IPC fields assessed, a score < 50% was graded poor, 50–75% as fair, while > 75% was rated as good. Results: Before the intervention, the first assessment (baseline) indicated that the majority of the health facilities scored low in terms of isolation facilities, IPC administration, supply and equipment, personnel and staffing, triage and waste management. Following the application of supportive supervision and monitoring, all the facilities recorded moderate to good performance in all the fields during the fourth round of assessment, except for isolation facilities, which scored low. Conclusion: Supportive supervision and monitoring of healthcare facilities appeared to have contributed to the improvement in IPC standards and compliance during the Ebola outbreak as demonstrated in this small-scale study and should be sustained as a core component of IPC programs, particularly in prolonged outbreak situations.

Published: July 2018

Objective: People with nondialysis-dependent chronic kidney disease (CKD) and renal transplant recipients (RTRs) have compromised physical function and reduced physical activity (PA) levels. Whilst established in healthy older adults and other chronic diseases, this association remains underexplored in CKD. We aimed to review the existing research investigating poor physical function and PA with clinical outcome in nondialysis CKD. Data sources: Electronic databases (PubMed, MEDLINE, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials) were searched until December 2017 for cohort studies reporting objective or subjective measures of PA and physical function and the associations with adverse clinical outcomes and all-cause mortality in patients with nondialysis CKD stages 1–5 and RTRs. The protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42016039060). Review methods: Study quality was assessed using the Newcastle-Ottawa Scale and the Agency for Healthcare and Research Quality (AHRQ) standards. Results: A total of 29 studies were included; 12 reporting on physical function and 17 on PA. Only eight studies were conducted with RTRs. The majority were classified as ‘good’ according to the AHRQ standards. Although not appropriate for meta-analysis due to variance in the outcome measures reported, a coherent pattern was seen with higher mortality rates or prevalence of adverse clinical events associated with lower PA and physical function levels, irrespective of the measurement tool used. Sources of bias included incomplete description of participant flow through the study and over reliance on self-report measures. Conclusions: In nondialysis CKD, survival rates correlate with greater PA and physical function levels. Further trials are required to investigate causality and the effectiveness of physical function and PA interventions in improving outcomes. Future work should identify standard assessment protocols for PA and physical function.
Ten years of EMS Fall Calls in a Community: An Opportunity for Injury Prevention Strategies
Authors: Quatman Carmen E. , Mondor Michael , Halweg Jodi , Switzer Julie A. 
Published: July 2018

Objective: To determine whether fall calls, lift assists, and need for transport to the hospital over the past 10 years in one emergency medical services (EMS) system have altered coincident with demographic changes and to estimate health-care cost for lift assists. Methods: We conducted a retrospective chart review of EMS fall-related care. The HealthEMS database for a suburban community surveyed was queried from March 1, 2007, to March 1, 2017. Fall-related calls in patients 60 years or older were identified and determined to be either lift assists (calls that do not result in transport) or fall calls that resulted in transport to the hospital. Results: Of the 38 237 EMS care responses in patients 60 years or older, 11.5% were related to falls. Fall calls increased by 268% over the past 10 years ( P = .0006), yet the number of transports to the hospital significantly decreased over time ( P = .02). Lift assists increased significantly ( P = .0003), nearly doubling over the decade. At the same time, fall calls that did not result in transport to the hospital cost the community an estimated US$1.5 million over a 10-year period. Discussion: There has been a dramatic shift in fall-related calls to EMS in older individuals with more frequent calls for lesser acuity needs. Utilization of EMS for lift assists has substantial financial consequences and diverts care from calls that need immediate triage and transport to care. Conclusion: Future work to reduce the frequency and increase the impact of EMS lift assists could have a significant cost benefit and provide opportunity for enrollment in appropriate community services and fall prevention programs.
Middlebackite, a new Cu oxalate mineral from Iron Monarch, South Australia: Description and crystal structure
Authors: Elliott Peter 
Published: July 2018

AbstractMiddlebackite is a new supergene mineral formed in the upper levels of the Iron Monarch quarry, South Australia. It occurs as aggregates of blue, prismatic crystals up to 0.3 mm across comprising individual crystals up to 0.05 mm in length associated with atacamite and mottramite. Crystals are translucent with a vitreous lustre and have a pale blue streak. Middlebackite is brittle with one perfect cleavage and uneven fracture. Mohs hardness is ~2. The calculated density is 3.64 g cm–3. Crystals are biaxial (+) with α = 1.663(4), β = 1.748(4) and γ = 1.861(4) (measured in white light). The calculated 2V is 86.7°. Pleochroism isX= colourless,Y= very pale blue andZ= dark sky blue;Z&gt;Y&gt;X. The empirical formula unit, based on six oxygen atoms per formula unit is Cu2.00(C2O4)Cl0.02(OH)1.98. Middlebackite is monoclinic, space groupP21/c witha= 7.2597(15),b= 5.7145(11),c= 5.6624(11) Å, β = 104.20(3)°,V= 227.73(8) Å3andZ= 2. The five strongest lines in the powder X-ray diffraction pattern are [d(Å), (I), (hkl)]: 7.070 (16) (100), 3.739 (100) (11$\bar{1}$), 2.860 (18) (020), 2.481 (12) (12$\bar{1}$) and 2.350 (9) (300). The crystal structure was refined from synchrotron single-crystal X-ray diffraction data toR1= 0.0341 for 596 observed reflections withF0&gt; 4σ(F0). The structure is based on sheets of edge- and corner-sharing octahedra parallel to thebcplane. Sheets link in theadirection via oxalate anions.

Published: July 2018

AbstractBackgroundFoot problems in people with rheumatoid arthritis (RA) are highly prevalent and have a substantial impact on quality of life. Healthcare professionals from various professions can be involved in the management of these foot problems. There is currently no consensus on optimal management. Therefore, the aim of the present study was to develop multidisciplinary recommendations for the management of foot problems in people with RA in the Netherlands.MethodsThe recommendations were based on research evidence and consensus among experts, following published strategies for the development of practice recommendations. The expert group was composed of 2 patients and 22 experienced professionals (rheumatologists, rehabilitation physicians, orthopaedic surgeons, specialized nurses, podiatrists, orthopaedic shoe technicians, pedicurists, and researchers) in the Netherlands. For each developed recommendation i) the level of evidence was determined, and ii) the level of agreement (among the expert group) was set by an anonymous voting procedure using a numeric rating scale. The mean and range of the level of agreement for each recommendation was calculated. A recommendation was approved when ≥70% of the expert group voted an NRS‐agreement ≥7.ResultsIn total, 41 recommendations were developed. Two recommendations concerned a framework for diagnosis and treatment. Thirty‐nine recommendations on foot care were developed: seven on diagnosis (including check‐ups of feet and shoes and diagnostic imaging), 27 on treatment (including corticosteroid injections, foot surgery, therapeutic shoes, foot orthoses, exercise therapy, toe‐orthoses and toenail‐braces, treatment of toenails and skin), four on communication, and one on organisation of RA‐related footcare. All recommendations were approved by the expert group. The percentage score of NRS‐agreement ≥7 ranged from 80 to 100%.ConclusionsThese are the first published multidisciplinary recommendations specific to the management of foot problems in people with RA. Multidisciplinary recommendations can provide guidance in timely referrals and access to adequate footcare. More research is needed to strengthen the evidence on diagnosis and treatment of RA‐related foot problems. These national recommendations may be a first step towards developing international multidisciplinary recommendations for the management of foot problems in RA.

Authors: Hsu Ying-Chieh , Kuo Chin-Lung , Huang Tzu-Chin 
Published: July 2018

Background This study compares endoscopic and microscopic tympanoplasty for the treatment of chronic otitis media (COM) without cholesteatoma. Methods This retrospective study included 153 ears (139 patients) treated surgically (endoscopic or microscopic tympanoplasty) for COM in the absence of cholesteatoma at our hospital between January 2008 and October 2015. The adoption of transcanal endoscopic ear surgery (TEES) or microscopic ear surgery (MES) was divided temporally (before and since 2014). Comparisons between these groups focused on the following: (I) surgical outcomes, including successful tympanic membrane healing and post-operative complications; (II) restoration of hearing; and (III) consumption of medical resources, including the duration of surgery and anesthesia. All patients had a follow-up period of at least 3 months after surgery. Results No statistically significant differences were observed between the two groups regarding surgical outcome or hearing restoration. TEES resulted in the successful healing of 96.2% of ear drums, whereas MES led to successful healing in 92% ( p = 0.2826) of cases. The average hearing gains following surgery were 10.27 ± 6.4 and 12.43 ± 7.46 dB in TEES and MES, respectively. The consumption of medical resources in the TEES group was lower than that of the MES group (TEES versus MES) regarding the average operating time (87.8 ± 19.01 min (mins) versus 110.2 ± 17.0 (mins) ( p <  0.0001)) and the mean duration of anesthesia ((for general anesthesia patients) (122.1 ± 21.25 mins versus 145.8 ± 16.88 mins) ( p ≤  0.0001)). Conclusions The results indicate that TEES can achieve surgical outcomes and hearing restoration comparable to those of MES. In addition, TEES appears to be associated with shorter surgical and anesthesia time, which makes it an ideal alternative for the management of COM without cholesteatoma. Trial registration This study was approved by the Institutional Review Board of the Cathay General Hospital. (CGHIRB No: CGH-P105012 ).
Hypoxia-inducible transcription factors in fish: expression, function and interconnection with the circadian clock
Authors: Pelster Bernd , Egg Margit 
Published: July 2018

ABSTRACTThe hypoxia-inducible transcription factors are key regulators for the physiological response to low oxygen availability. In vertebrates, typically three Hif-α isoforms, Hif-1α, Hif-2α and Hif-3α, are expressed, each of which, together with Hif-1β, may form a functional heterodimer under hypoxic conditions, controlling expression of hundreds of genes. A teleost-specific whole-genome duplication complicates the analysis of isoform-specific functions in fish, but recent studies suggest that the existence of paralogues of a specific isoform opens up the possibility for a subfunctionalization. In contrast to during development inside the uterus, fish eggs are freely accessible and studies analyzing Hif expression in fish embryos during development have revealed that Hif proteins are not only controlling the hypoxic response, but are also crucial for proper development and organ differentiation. Significant advances have been made in our knowledge about tissue-specific functions of Hif proteins, especially with respect to gill or gonadal tissue. The hypoxia signalling pathway is known to be tightly and mutually intertwined with the circadian clock in zebrafish and mammals. Recently, a mechanistic explanation for the hypoxia-induced dampening of the transcriptional clock was detected in zebrafish, including also metabolically induced alterations of cellular redox signalling. In turn, MAP kinase-mediated H2O2 signalling modulates the temporal expression of Hif-1α protein, similar to the redox regulation of the circadian clock itself. Once again, the zebrafish has emerged as an excellent model organism with which to explore these specific functional aspects of basic eukaryotic cell biology.

Authors: Hamze Layal , Carrick-Sen Debbie , Zhang Zeyu , Liu Yijuan , Mao Jing 
Published: July 2018

Background Mother and infant benefits of breastfeeding have been confirmed globally. Maternal attitude is a significant predictor for intention, initiation and continuation of breastfeeding, and is a multi-faceted and frequently-used concept. Aims To undertake a literature review and concept analysis of maternal attitude related to breastfeeding. Methods Walker and Avant's eight-step framework was used. Findings Attitude is a multi-faceted, frequently-used concept. Four critical attributes were identified: making a judgment based on beliefs, experience, knowledge and/or principles; feelings and thoughts towards a specific topic; a decision to agree, disagree or remain neutral; and consideration of behaviour and/or action change (or a decision not to take action). The review suggests that health professionals could apply the assessment of patient attitude to achieve desired behaviour. Conclusion Maternal attitude was related to intention, initiation and continuation of breastfeeding.

Abstract – The atomic structure at surface of the layered perovskite Ca1.9Sr0.1RuO4 has been studied by Low Energy Electron Diffraction (LEED) I-V. The perovskite Ca1.9Sr0.1RuO4 of single crystal was cleaved in ultra high vacuum chamber (the pressure in the chamber was about 1x10-10 Torr). The experiments were conducted at room temperature (T=300 K). The sharp LEED pattern was observed which indicates that the surface of Ca1.9Sr0.1RuO4 is flat and it is a well ordered crystal. LEED I-V data, nine equivalent beams of the layered perovskite Ca1.9Sr0.1RuO4 were recorded at room temperature. LEED I-V calculation was performed to fit experimental data to obtain the surface atomic structure. The LEED I-V analysis reveals that in the surface of the layered perovskite Ca1.9Sr0.1RuO4 the RuO6 octahedra are rotated (in-plane rotation) alternating clockwise and counterclockwise. The in-plane rotation at the surface is 11 degree which is smaller than that in the bulk (13 degree). The Ru – O(1) bond-length at the surface is found to be 1.936 Å which is about the same as in the bulk (1.939 Å). The Ru – O(2) bond length at the surface is 1.863 Å which is much shorter than that in the bulk (2.040 Å). The volume of octahedral Ru-O6 at the surface is reduced by 9% with respect to the bulk. This finding shows that the atomic structure at surface of the layered perovskite Ca1.9Sr0.1RuO4is significantly different than that in the bulk. These lattice distortions strongly influence its electronic properties. Key words: Transition Metal Oxide; Perovskite; Surface Atomic Structure; LEED I-V

A research was conducted for the optimization of the turning process st 60 tool steel with multiple performance characteristics based on the orthogonal array with Taguchi-WPCA method. Minimum Quantity Cooling Lubrication (MQCL) metode was applied as a coolant. The experimental studies were conducted under varying the cutting speed, feeding, depth of cut and type of coolant. The optimized multiple performance characteristics were surface roughness, and material removal rate. An orthogonal array, signal-to-noise ratio, grey relational analysis, weighted pricipal component analysis and analysis of variance were employed to study the multiple performance characteristics. Experimental results show that cutting speed gives the highest contribution for minimize of surface roughness and maximize of material removal rate, followed by feeding speed, type of coolant and depth of cut. The minimum of surface roughness and maximize of material removal rat could be obtained by using the values of cutting speed, feeding speed, depth of cut and type of coolant of 172.95 m/minute, 0.053 mm/rev, 0.25 mm, and vegetable oil as a coolant respectively.
Las raíces agustinianas de la conceptualidad de "Ser y Tiempo"
Authors: Klocker Dante 
Published: July 2018

La progresiva publicación a lo largo de las últimas dos décadas de los cursos dictados por Heidegger durante sus primeros años de docencia ha permitido reconstruir el proceso de gestación de Ser y Tiempo (1927), sus múltiples referencias textuales e influencias. Entre ellas, ocupa un lugar destacado el pensamiento agustiniano, por lo cual me propongo considerar aquí su fuerte presencia en algunos de los conceptos centrales de dicha obra.
El primero a tener en cuenta es el de “Sorge” (preocupación, cuidado) con el que Heidegger caracteriza la constitución ontológica fundamental del existir humano. Sus primeros esbozos habían surgido de la reflexión en torno al célebre “inquietum cor nostrum” y a la cura por la vita beata de Confesiones X. A partir de este mismo texto Heidegger había realizado también una interpretación fenomenológica de la tentación, que constituye una de las primeras elaboraciones de la llamada “caída”, precisamente uno de los momentos estructurales de la “Sorge”.
Referencias explícitas o sugerentes analogías entre ambos pensadores pueden apreciarse también entre la explicación de Confesiones XI del “tempus” como “distentio animi” y la tesis heideggeriana de la “temporalidad” como fundamento de la constitución de la subjetividad humana; el tránsito desde la búsqueda de Dios a la exploración de la interioridad de aquel que lo busca y el retroceso desde la pregunta por el “ser” a la pregunta por el que comprende el “ser”, entre otros casos no menos significativos.
