Comparable, but distinct: Perceptions of primary care provided by physicians and nurse practitioners in full and restricted practice authority states

AimsTo understand patients- and providers- perceptions of primary care delivered by nurse practitioners (NPs) in the Veterans Affairs Healthcare System.DesignQualitative exploratory study (in convergent mixed- methods design).MethodsSemi- structured interviews in 2016 with primary care providers and patients from facilities in states with full and restricted practice authority for NPs. Patient sample based on reassignment to: (a) a NP; or (b) a different physician following an established physician relationship. Data were analysed using content analysis.ResultsWe interviewed 28 patients, 17 physicians and 14 NPs. We found: (a) NPs provided more holistic care than physicians; (b) patients were satisfied with NPs; and (c) providers- professional experience outweighed provider type.ConclusionsPatients- preferences for NPs (compared with prior physicians) contributed to perceptions of patient centredness. Similarities in providers- perceptions suggest NPs and physicians are both viable providers for primary care.ImpactNurse Practitioners (NPs): practice authorityVeterans Affairs Health care: nurse practitioners will continue to be a viable resource for primary care deliveryUnited States Health care: challenges notions patients may not be satisfied with care provided by NPs and supports expanding their use to provide much- needed access to primary care services; expanding Full Practice Authority would allow states to provide acceptable primary care without diminishing patient or provider experiencesæ è¦ ç ®æ  äº è§£æ £è å å »ç æ ºæ 对é ä¼ å äººå »ç ä¿ å ¥ç³»ç» ä¸­æ ¤ç å¸ æ ä¾ å çº§æ ¤ç ç ç æ³ ã è®¾è®¡æ ¢ç´¢æ §ç å® æ §ç  ç©¶(æ ¶æ æ··å æ ¹æ³ è®¾è®¡)ã æ ¹æ³ 2016å¹´è¿ è¡ ç å ç» æ å è®¿è° ,é è®¿äº å· å æ ¥æ æ ¤ç å¸ ç å ¨ç§ å é å ¨ç§ æ §ä¸ æ ºæ ç å çº§æ ¤ç æ ä¾ è å æ £è ã é æ °å é æ £è æ ·æ ¬:(a) ä¸ å æ ¤ç å¸ ;æ (b)ç¡®ç« å »ç å ³ç³»ç å ¦ä¸ å å »ç ã é ç ¨å 容å æ æ³ å¯¹æ °æ ®è¿ è¡ å æ ã ç» æ æ 们é è®¿äº 28å æ £è ,17å å »ç å 14å æ ¤ç å¸ ã æ 们å ç °:(a)æ ¤ç å¸ æ¯ å »ç æ ä¾ ç æ ¤ç æ ´å ¨é ¢;(b)æ £è å¯¹æ ¤ç å¸ æ å °æ»¡æ ;(c)å »ç æ ºæ ç ä¸ ä¸ ç» éª ç æ é æ¯ å »ç æ ºæ ç±»å ç æ é æ ´å¤§ã ç» è®ºæ £è å¯¹æ ¤ç å¸ ç å 好(ä¸ ä»¥å ç å »ç ç ¸æ¯ )æ å ©äº å»ºç« ä»¥æ £è ä¸ºä¸­å¿ ç è®¤ç ¥ã æ ä¾ è ç è§ å¿µç±»ä¼¼,表æ æ ¤ç å¸ å å »ç é ½æ ¯å ¯è¡ ç å çº§æ ¤ç æ ä¾ è ã å½±å - ¢æ ¤ç å¸ :æ §ä¸ æ ºæ - ¢é ä¼ å äººå »ç ä¿ å ¥ç³»ç» :æ ¤ç å¸ å° ç»§ç»­ä½ ä¸ºæ ä¾ å çº§æ ¤ç æ å ¡ç å ¯ç ¨èµ æº ã - ¢ç¾ å ½å «ç ä¿ å ¥:æ æ è§ å¿µ æ £è å ¯è ½ä¸ æ»¡æ ç ±æ ¤ç å¸ æ ä¾ ç æ ¤ç ,å ¶ä¼ æ ¯æ æ ©å¤§ä½¿ç ¨è å ´,以æ ä¾ æ ¥é ç å çº§ä¿ å ¥æ å ¡;æ ©å¤§å ¨ç§ æ §ä¸ æ ºæ å° ä½¿å å· è ½å¤ æ ä¾ å ¯æ ¥å ç å çº§ä¿ å ¥æ å ¡,è ä¸ ä¼ å å¼±æ £è æ æ ä¾ è ç ä½ éª ãPeer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/163369/2/jan14501.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/163369/1/jan14501_am.pd

Approximate k-state solutions to the Dirac-Yukawa problem based on the spin and pseudospin symmetry

Using an approximation scheme to deal with the centrifugal (pseudo-centrifugal) term, we solve the Dirac equation with the screened Coulomb (Yukawa) potential for any arbitrary spin-orbit quantum number {\kappa}. Based on the spin and pseudospin symmetry, analytic bound state energy spectrum formulas and their corresponding upper- and lower-spinor components of two Dirac particles are obtained using a shortcut of the Nikiforov-Uvarov method. We find a wide range of permissible values for the spin symmetry constant C_{s} from the valence energy spectrum of particle and also for pseudospin symmetry constant C_{ps} from the hole energy spectrum of antiparticle. Further, we show that the present potential interaction becomes less (more) attractive for a long (short) range screening parameter {\alpha}. To remove the degeneracies in energy levels we consider the spin and pseudospin solution of Dirac equation for Yukawa potential plus a centrifugal-like term. A few special cases such as the exact spin (pseudospin) symmetry Dirac-Yukawa, the Yukawa plus centrifugal-like potentials, the limit when {\alpha} becomes zero (Coulomb potential field) and the non-relativistic limit of our solution are studied. The nonrelativistic solutions are compared with those obtained by other methods.Comment: 21 pages, 6 figure

Female leadership in French voluntary associations

Drawing on a recent national survey, this paper focuses on the female representation on executive committees in French voluntary associations. To begin with, we observe that this representation is very unequal according to the different officer positions. It is especially low among presidents. Then we study the relationship between the associations' attributes and the likelihood of women being appointed as executive committee members. We notice that the probabilities that women hold president, treasurer and secretary positions are highly correlated to each other. We find that the proportion of female officers is higher in organizations whose activities pertain to social service, health and humanitarian sectors. It is lower in the oldest associations and it decreases as their geographical area of activity increases and as their budget becomes larger. The probability that associations have female presidents is higher in associations with few volunteers

Radiation and breast cancer: a review of current evidence

This paper summarizes current knowledge on ionizing radiation-associated breast cancer in the context of established breast cancer risk factors, the radiation dose–response relationship, and modifiers of dose response, taking into account epidemiological studies and animal experiments. Available epidemiological data support a linear dose–response relationship down to doses as low as about 100 mSv. However, the magnitude of risk per unit dose depends strongly on when radiation exposure occurs: exposure before the age of 20 years carries the greatest risk. Other characteristics that may influence the magnitude of dose-specific risk include attained age (that is, age at observation for risk), age at first full-term birth, parity, and possibly a history of benign breast disease, exposure to radiation while pregnant, and genetic factors

Mutator Suppression and Escape from Replication Error–Induced Extinction in Yeast

Cells rely on a network of conserved pathways to govern DNA replication fidelity. Loss of polymerase proofreading or mismatch repair elevates spontaneous mutation and facilitates cellular adaptation. However, double mutants are inviable, suggesting that extreme mutation rates exceed an error threshold. Here we combine alleles that affect DNA polymerase δ (Pol δ) proofreading and mismatch repair to define the maximal error rate in haploid yeast and to characterize genetic suppressors of mutator phenotypes. We show that populations tolerate mutation rates 1,000-fold above wild-type levels but collapse when the rate exceeds 10−3 inactivating mutations per gene per cell division. Variants that escape this error-induced extinction (eex) rapidly emerge from mutator clones. One-third of the escape mutants result from second-site changes in Pol δ that suppress the proofreading-deficient phenotype, while two-thirds are extragenic. The structural locations of the Pol δ changes suggest multiple antimutator mechanisms. Our studies reveal the transient nature of eukaryotic mutators and show that mutator phenotypes are readily suppressed by genetic adaptation. This has implications for the role of mutator phenotypes in cancer
