    Full Text Available Purpose. To investigate the clinical efficacy and safety of combined phacoemulsification with goniosynechialysis (GSL under an ophthalmic endoscope for chronic primary angle-closure glaucoma and coexisting cataract. Methods. This is a retrospective study. The intraocular pressure (IOP, best-corrected visual acuity (BCVA, and number of glaucoma medications at baseline and each postoperative follow-up visit were recorded. Other measurements included supraciliochoroidal fluid measured by anterior segment optical coherence tomography, corneal endothelial cell density (ECD, and peripheral anterior synechia (PAS. All patients were followed for more than a year. Results. Thirty-eight eyes of 31 patients were included. The mean follow-up duration was 16.3 ± 3.9 months. The IOP decreased from 22.2 ± 9.3 mmHg at baseline to 15.4 ± 4.2 mmHg at the last follow-up (P<0.001. The mean number of glaucoma medications (0.1 ± 0.6 at the last follow-up was significantly lower than the preoperative number (2.3 ± 1.1 (P<0.001. All patients achieved improved or stable visual acuity after surgery. All patients achieved a complete opened angle after GSL. The postoperative complications included hyphema (7.9%, exudation (5.3%, transiently elevated IOP (55.3%, and supraciliochoroidal fluid (40%. Conclusions. Combined phacoemulsification and GSL under an endoscope can completely reopen PAS and is an effective and safe method for patients with chronic primary angle-closure glaucoma and coexisting cataract.

    Primary angle closure is a condition characterized by obstruction to aqueous humor outflow by the peripheral iris, and results in changes in the iridocorneal angle that are visible through gonioscopic examination. Gonioscopy in these eyes, however, can be difficult. This chapter discusses techniques that might help in the examination. These include beginning the examination with the inferior angle, methods to help in looking over the iris, cycloplegia, locating the corneal wedge, indentation, van Herick estimation, examining the other eye, and topical glycerin. Finally, there is a discussion about the pathology associated with the closed angle, with emphasis on the appearance of iris bombé, plateau iris, and the distinction between iris processes and peripheral anterior synechiae.

    Three related myopic individuals with primary angle closure glaucoma are reported. They had true myopia and not pseudomyopia secondary to increased lenticular index of refraction. We believe one of these individuals (-8.62 spherical equivalent) to have the most myopic case of primary angle closure glaucoma reported in the literature. Although myopia is associated with anatomical factors that offer considerable protection from primary angle closure glaucoma, its presence does not eliminate the possibility of this disease. Laser iridectomy was effective in the treatment of these patients.

    To determine the relationship between iris surface features and acute primary angle closure (APAC) in eyes with angle closure. Case-control study involving Asian patients diagnosed with previous APAC, primary angle closure suspect (PACS), primary angle closure (PAC) and primary angle closure glaucoma (PACG) at an eye centre in Singapore between August 2012 and January 2015. Participants underwent ophthalmic examination and digital slit-lamp iris photography. Iris surface features were graded based on crypts, furrows and colour. Fellow eyes of APAC were compared with PACS and PAC/PACG eyes with regard to their iris surface features. Occurrence of APAC. A total of 309 patients (71 APAC, 139 PACS, 47 PAC and 52 PACG) were included (mean age: 67.7±7.2 years and 36.6% male). Compared with PACS, higher crypt grade was significantly associated with lower odds of APAC (OR=0.58 for one grade higher in crypt grade; p=0.027, adjusted for age, gender, ethnicity and pupil diameter). The results remained similar when compared with PAC/PACG group (OR=0.58 for one grade higher in crypt grade; p=0.043). We did not observe any significant associations between iris furrows or colour with presence of APAC. Our study comprising Asian eyes with angle closure suggests that the presence of a higher crypt grading may be protective for APAC. As such, assessing iris surface architecture for crypts could be a new measure for risk stratification of developing APAC in eyes with angle closure. Published by the BMJ Publishing Group Limited.

    To compare the interocular asymmetry of visual field loss in newly diagnosed normal-tension glaucoma (NTG), primary open-angle glaucoma (POAG), and chronic angle-closure glaucoma (CACG) patients. Visual field results of 117 newly diagnosed, treatment-naive glaucoma patients (42 NTG, 38 POAG, and 37 CACG) were studied retrospectively. The following 3 visual field defect parameters were used to evaluate the interocular asymmetry: (1) global indices; (2) local mean deviations (MDs) of 6 predefined visual field areas; and (3) stage designated by glaucoma staging system 2. The differences of the above parameters between the trial eye (the eye with greater MDs) and the fellow eye in each subject were defined as interocular asymmetry scores. Interocular asymmetry of visual field loss was presented in all the 3 groups (all P0.05). Interocular asymmetry scores of glaucoma staging system 2 had no significant difference among the 3 groups (P=0.068). All CACG, POAG, and NTG groups presented with interocular asymmetric visual field loss at the time of diagnosis. CACG had greater interocular asymmetry compared with NTG and POAG. No significant interocular asymmetry difference was observed between NTG and POAG.

    Full Text Available A 59-year-old man with a history of longstanding systemic hypotension developed asymmetric non-arteritic anterior ischemic optic neuropathy (NAION apparently precipitated by bilateral sequential acute primary angle closure. NAION is very rarely reported in association with raised intraocular pressure. In contrast to optical coherence tomography, the failure of scanning laser polarimetry to detect axonal swelling was another interesting finding. Possible reasoning for these observations is discussed.

    Full Text Available Background. Retinitis pigmentosa (RP comprises a group of inherited disorders in which patients typically lose night vision in adolescence and then lose peripheral vision in young adulthood before eventually losing central vision later in life. A retrospective case-control study was performed to evaluate differences in ocular biometric parameters in primary angle-closure glaucoma (PACG patients with and without concomitant RP to determine whether a relationship exists between PACG and RP. Methods. We used ultrasound biomicroscopy (UBM to measure anterior chamber depth (ACD. A-scan biometry was carried out to measure lens thickness (LT and axial length (AL. Propensity score matching and mixed linear regression model analysis were conducted. 23 patients with chronic primary angle-closure glaucoma (CPACG associated with RP, 21 patients with acute primary angle-closure glaucoma (APACG associated with RP, 270 patients with CPACG, and 269 patients with APACG were recruited for this study. Results. There were no significant differences on ACDs, ALs, and relative lens position (RLP (P>0.05 between patients with PACG associated with RP and patients with PACG; however, patients with APACG associated with RP had a significantly greater LT than patients with APACG (P<0.05. Conclusion. Patients with PACG associated with RP had the same biometric parameter characteristic as the patients with CPACG and APACG. This may suggest that RP is a coincidental relationship with angle-closure glaucoma.

    Full Text Available Argon laser iridoplasty was performed in 40 eyes of 33 patients of primary angle closure glaucoma. There were 12 male and 21 female patients. The mean ages of the male and female patients were 51 years and 48.4 years respectively. Forty eyes were divided into two groups. Group I consisted of ten eyes of subacute angle closure glaucoma and group II included thirty eyes of chronic angle closure glaucoma. Argon laser iridoplasty was performed with Coherent 9000 model using laser settings of spot size 200 micron, duration 0.2 second and power 0.7 watt. A total of 80 spots were applied over 360 degree circumference. The intraocular pressure control (below 22 mm Hg was achieved after iridoplasty in all the eyes (100% in group I, where as in group II the intraocular pressure was controlled in 70% eyes. The follow up period varied from 3 months to one year with a mean of eight months. The success rate with iridoplasty was directly related to the extent of peripheral anterior synechiae, optic disc cupping and presence of visual field changes.

All patients underwent ophthalmologic examinations including measurement of visual acuity, best-corrected visual acuity, and IOP; biomicroscopy; specular microscopy; fundus examination; and gonioscopy followed by anterior chamber paracentesis and GSL for nasal peripheral anterior synechiae in the eye with severe CACG.Results: Thirty patients (18 men, 12 women were identified as having CACG with an initial mean IOP of 47.1 ± 6.7 mmHg (range 39–61 mmHg in the severely affected eye. One week after GSL, the mean IOP of the treated eyes decreased to 19.3 ± 2.8 mmHg (range 14–26 mmHg without antiglaucoma medication (average decrease 27.7 ± 6.5 mmHg; range 16–41 mmHg, which was significant (P < 0.00001 compared with baseline. After an average follow-up period of 36.6 ± 1.0 months (range 35–38 months, the mean IOP stabilized at 17.4 ± 2.2 mmHg (range 12–21 mmHg. The nasal angle recess did not close again in any one of the patients during the follow-up period. The average significant (P < 0.00001 decrease in corneal endothelial cell density in the treated eyes was 260 ± 183 cells/mm2 (range 191–328 cells/mm2.Conclusions: Anterior chamber paracentesis and GSL lowers IOP in advanced CACG, though it may lead to mild corneal endothelial cell loss

    Full Text Available AIM: To evaluate changes of proinflammatory cytokines in aqueous humor of patients with acute primary angle-closure (APAC and age-related cataracts. METHODS: Twenty eyes of 20 APAC patients and 15 eyes of 15 age-related cataract patients were included in this cross-sectional study. Aqueous humor samples were collected prospectively. The levels of 20 proinflammatory cytokines were evaluated in the aqueous humor of the APAC and cataract patients using the multiplex bead immunoassay technique. Clinical data were collected for correlation analysis. RESULTS: Seven of the 20 proinflammatory cytokines included in the magnetic bead panel were detectable in both APAC eyes and cataract eyes: interleukin (IL-10, IL-12, IL-15, IL-21, IL-6, chemokine (C-C motif ligand 20, and tumor necrosis factor alpha (TNF-α. IL-27 was only detectable in APAC eyes. Compared with the cataract eyes, the APAC eyes had significantly elevated concentrations of IL-12 (P=0.036, IL-15 (P=0.001, IL-6 (P=0.012, and IL-27 (only detectable in APAC eyes. Age was positively correlated with IL-12 (P=0.022 and IL-6 (P=0.037, and time elapsed between APAC onset and aqueous humor samples collection was positively correlated with IL-15 (P=0.037, IL-27 (P=0.040, and TNF-α (P=0.042. CONCLUSION: Several proinflammatory cytokines including IL-12,IL-15, IL-6 and IL-27, were elevated in the APAC eyes and may be implicated in its pathologic mechanism.

    To determine longitudinal changes in angle configuration in the eyes of primary angle-closure suspects (PACS) treated by laser peripheral iridotomy (LPI) and in untreated fellow eyes. Longitudinal cohort study. Primary angle-closure suspects aged 50 to 70 years were enrolled in a randomized, controlled clinical trial. Each participant was treated by LPI in 1 randomly selected eye, with the fellow eye serving as a control. Angle width was assessed in a masked fashion using gonioscopy and anterior segment optical coherence tomography (AS-OCT) before and at 2 weeks, 6 months, and 18 months after LPI. Angle width in degrees was calculated from Shaffer grades assessed under static gonioscopy. Angle configuration was also evaluated using angle opening distance (AOD250, AOD500, AOD750), trabecular-iris space area (TISA500, TISA750), and angle recess area (ARA) measured in AS-OCT images. No significant difference was found in baseline measures of angle configuration between treated and untreated eyes. At 2 weeks after LPI, the drainage angle on gonioscopy widened from a mean of 13.5° at baseline to a mean of 25.7° in treated eyes, which was also confirmed by significant increases in all AS-OCT angle width measures (Pgonioscopy (P = 0.18), AOD250 (P = 0.167) and ARA (P = 0.83). In untreated eyes, angle width consistently decreased across all follow-up visits after LPI, with a more rapid longitudinal decrease compared with treated eyes (P values for all variables ≤0.003). The annual rate of change in angle width was equivalent to 1.2°/year (95% confidence interval [CI], 0.8-1.6) in treated eyes and 1.6°/year (95% CI, 1.3-2.0) in untreated eyes (P<0.001). Angle width of treated eyes increased markedly after LPI, remained stable for 6 months, and then decreased significantly by 18 months after LPI. Untreated eyes experienced a more consistent and rapid decrease in angle width over the same time period. Copyright © 2014 American Academy of Ophthalmology. Published by

    Primary angle closure disease spectrum varies from a narrow angle to advanced glaucoma. A variety of imaging technologies may assist the clinician in determining the pathophysiology and diagnosis of primary angle closure, but gonioscopy remains a mainstay of clinical evaluation. Laser iridotomy effectively eliminates the pupillary block component of angle closure; however, studies show that in many patients the iridocorneal angle remains narrow from underlying anatomic issues, and increasing lens size often leads to further narrowing over time. Recent studies have further characterized the role of the lens in angle closure disease, and cataract or clear lens extraction is increasingly used earlier in its management. As a first surgical step in angle closure glaucoma, lens extraction alone often effectively controls the pressure with less risk of complications than concurrent or stand alone glaucoma surgery, but may not be sufficient in more advanced or severe disease. We provide a comprehensive review on the primary angle-closure disease nomenclature, imaging, and current laser and surgical management. Copyright © 2018. Published by Elsevier Inc.

    To evaluate noncontact anterior segment optical coherence technology (AS-OCT) as a qualitative method of imaging the anterior chamber angle and to determine its ability to detect primary angle closure when compared with gonioscopy in Asian subjects. Prospective observational case series. Two hundred three subjects were recruited from glaucoma clinics in Singapore with diagnoses of primary angle closure, primary open-angle glaucoma, ocular hypertension, or cataract. Both eyes (if eligible) of each patient were included in the study. Exclusion criteria were pseudophakia or previous glaucoma surgery. Images of the nasal, temporal, and inferior angles were obtained with AS-OCT in dark and then light conditions. Gonioscopic angle width was graded using the Spaeth classification for each quadrant in low lighting conditions. Angle closure was defined by AS-OCT as contact between the peripheral iris and angle wall anterior to the scleral spur and by gonioscopy as a Spaeth grade of 0 degree (posterior trabecular meshwork not visible). Comparison of the 2 methods in detecting angle closure was done by eye and by individual. Sensitivities and specificities of AS-OCT were calculated using gonioscopy as the reference standard. Complete data were available for 342 eyes of 200 patients. Of the patients, 70.9% had a clinical diagnosis of treated or untreated primary angle closure. Angle closure in > or =1 quadrants was detected by AS-OCT in 142 (71%) patients (228 [66.7%] eyes) and by gonioscopy in 99 (49.5%) patients (152 [44.4%] eyes). The inferior angle was closed more frequently than the nasal or temporal quadrants using both AS-OCT and gonioscopy. When performed under dark conditions, AS-OCT identified 98% of those subjects found to have angle closure on gonioscopy (95% confidence interval [CI], 92.2-99.6) and led to the characterization of 44.6% of those found to have open angles on gonioscopy to have angle closure as well. With gonioscopy as the reference standard

    Acute angle closure (AAC) without prompt treatment may lead to optic neuropathy. Environmental factor such as climate change may precipitate pupillary block, the possible mechanism of AAC. To determine the association of northeast monsoon and incidence of AAC in Malaysia. A retrospective study was conducted on AAC patients admitted to two main tertiary hospitals in Kelantan, Malaysia between January 2001 and December 2011. The cumulative number of rainy day, amount of rain, mean cloud cover and 24 hours mean humidity at the estimated day of attack were obtained from the Department of Meteorology, Malaysia. A total 73 cases of AAC were admitted with mean duration of 4.1SD 2.0 days. More than half have previous history of possibility of AAC. There was higher incidence of AAC during the northeast monsoon (October to March). There was also significant correlation of number of rainy day (r=0.718, pclimate as the potential risk factor. Prompt treatment to arrest pupillary block and reduction of the intraocular pressure is important to prevent potential glaucomatous damage. Public awareness of AAC and accessibility to treatment should be part of preparation to face the effect of northeast monsoon.

    To determine if trabecular meshwork (TM) height differs between primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) eyes. Prospective, cross-sectional clinical study. Adult patients were consecutively recruited from glaucoma clinics at the University of California, San Francisco, from January 2012 to July 2015. Images were obtained from spectral-domain optical coherence tomography (Cirrus OCT; Carl Zeiss Meditec, Inc, Dublin, California, USA). Univariate and multivariate linear mixed models comparing TM height and glaucoma type were performed to assess the relationship between TM height and glaucoma subtype. Mixed-effects regression was used to adjust for the use of both eyes in some subjects. The study included 260 eyes from 161 subjects, composed of 61 men and 100 women. Mean age was 70 years (SD 11.77). There were 199 eyes (123 patients) in the POAG group and 61 eyes (38 patients) in the PACG group. Mean TM heights in the POAG and PACG groups were 812 ± 13 μm and 732 ± 27 μm, respectively, and the difference was significant in univariate analysis (P = .004) and in multivariate analysis (β = -88.7 [24.05-153.5]; P = .008). In this clinic-based population, trabecular meshwork height is shorter in PACG patients compared to POAG patients. This finding may provide insight into the pathophysiology of angle closure and provide assistance in future diagnosis, prevention, and management of the angle-closure spectrum of disorders.

    To compare ocular biometric parameters using low-coherence interferometry among siblings affected with different degrees of primary angle closure (PAC). In this cross-sectional comparative study, a total of 170 eyes of 86 siblings from 47 families underwent low-coherence interferometry (LenStar 900; Haag-Streit, Koeniz, Switzerland) to determine central corneal thickness, anterior chamber depth (ACD), aqueous depth (AD), lens thickness (LT), vitreous depth, and axial length (AL). Regression coefficients were applied to show the trend of the measured variables in different stages of angle closure. To evaluate the discriminative power of the parameters, receiver operating characteristic curves were used. Best cutoff points were selected based on the Youden index. Sensitivity, specificity, positive and negative predicative values, positive and negative likelihood ratios, and diagnostic accuracy were determined for each variable. All biometric parameters changed significantly from normal eyes to PAC suspects, PAC, and PAC glaucoma; there was a significant stepwise decrease in central corneal thickness, ACD, AD, vitreous depth, and AL, and an increase in LT and LT/AL. Anterior chamber depth and AD had the best diagnostic power for detecting angle closure; best levels of sensitivity and specificity were obtained with cutoff values of 3.11 mm for ACD and 2.57 mm for AD. Biometric parameters measured by low-coherence interferometry demonstrated a significant and stepwise change among eyes affected with various degrees of angle closure. Although the current classification scheme for angle closure is based on anatomical features, it has excellent correlation with biometric parameters.

    Full Text Available Purpose: To study ultrastructural changes of the trabecular meshwork in acute and chronic primary angle closure glaucoma (PACG and primary open angle glaucoma (POAG eyes by scanning electron microscopy. Materials and Methods: Twenty-one trabecular meshwork surgical specimens from consecutive glaucomatous eyes after a trabeculectomy and five postmortem corneoscleral specimens were fixed immediately in Karnovsky solution. The tissues were washed in 0.1 M phosphate buffer saline, post-fixed in 1% osmium tetraoxide, dehydrated in acetone series (30-100%, dried and mounted. Results: Normal trabecular tissue showed well-defined, thin, cylindrical uveal trabecular beams with many large spaces, overlying flatter corneoscleral beams and numerous smaller spaces. In acute PACG eyes, the trabecular meshwork showed grossly swollen, irregular trabecular endothelial cells with intercellular and occasional basal separation with few spaces. Numerous activated macrophages, leucocytes and amorphous debris were present. Chronic PACG eyes had a few, thickened posterior uveal trabecular beams visible. A homogenous deposit covered the anterior uveal trabeculae and spaces. Converging, fan-shaped trabecular beam configuration corresponded to gonioscopic areas of peripheral anterior synechiae. In POAG eyes, anterior uveal trabecular beams were thin and strap-like, while those posteriorly were wide, with a homogenous deposit covering and bridging intertrabecular spaces, especially posteriorly. Underlying corneoscleral trabecular layers and spaces were visualized in some areas. Conclusions: In acute PACG a marked edema of the endothelium probably contributes for the acute and marked intraocular pressure (IOP elevation. Chronically raised IOP in chronic PACG and POAG probably results, at least in part, from decreased aqueous outflow secondary to widening and fusion of adjacent trabecular beams, together with the homogenous deposit enmeshing trabecular beams and spaces.

    Full Text Available AIM: To observe the curative effect of treating small-incision cataract extraction by intraocular lens implantation combined with trabeculectomy for primary angle-closure glaucoma with cataract. METHODS: Totally 44 cases(52 eyesof primary angle-closure glaucoma combined with cataract were selected to undergo the combined surgery, in order to observe the patients' pre- and postoperative eyesights, intraocular pressures and the postoperative complications.RESULTS: The postoperative eyesight was improved significantly as compared with the preoperative eyesight. The intraocular pressure was declined dramatically. The result was of statistical significance(P0.05. All the 52 cases' surgeries were performed by the same surgeon. The surgeries were processed smoothly, with 6 postoperative eyes of anterior chamber inflammation cell response, 3 eyes of anterior chamber fibrinoid exudate, 2 eyes of shallow anterior chamber through mydriasis and treatment with glucocorticoids and non-steroidal eyedrops before absorption, and no complications like malignant glaucoma, cyclodialysis, etc. were reported through mydriasis and pressure bandaging before recovery.CONCLUSION: Treating the primary angle-closure glaucoma combined with cataract through the combined surgery has high reliability and desirable curative effect. The surgical method is simple to learn and applicable for promotion on the basic level.

    Purpose To evaluate the change in trabecular-iris circumference volume (TICV) after laser peripheral iridotomy (LPI) in primary angle closure (PAC) spectrum eyes Patients and Methods Forty-two chronic PAC spectrum eyes from 24 patients were enrolled. Eyes with anterior chamber abnormalities affecting angle measurement were excluded. Intraocular pressure, slit lamp exam, and gonioscopy were recorded at each visit. Anterior segment optical coherence tomography (ASOCT) with 3D mode angle analysis scans were taken with the CASIA SS-1000 (Tomey Corp., Nagoya, Japan) before and after LPI. Forty-two pre-LPI ASOCT scans and 34 post-LPI ASOCT scans were analyzed using the Anterior Chamber Analysis and Interpretation (ACAI, Houston, TX) software. A mixed-effect model analysis was used to compare the trabecular-iris space area (TISA) changes among 4 quadrants, as well as to identify potential factors affecting TICV. Results There was a significant increase in all average angle parameters after LPI (TISA500, TISA750, TICV500, and TICV750). The magnitude of change in TISA500 in the superior angle was significantly less than the other angles. The changes in TICV500 and TICV750 were not associated with any demographic or ocular characteristics. Conclusion TICV is a useful parameter to quantitatively measure the effectiveness of LPI in the treatment of eyes with PAC spectrum disease. PMID:26066504

    Full Text Available AIM: To explore the change of postoperative macular structure in primary angle closure disease(PACDcomplicated with cataract. METHODS: The clinical data of 200 cases of PACD patients complicated with cataract treated in our hospital were analyzed retrospectively. The patients were divided into the Group A(n=60, 60 eyes, treated with trabeculectomy, the Group B(n=72, 72 eyes, given the phacoemulsification combined with intraocular lens implantationand the Group C(n=68, 68 eyes, given the trabeculectomy and phacoemulsification combined with intraocular lens implantation. The vision changes before and after treatment and the changes of intraocular pressure and macular thickness(foveal area, near central area, foveal surrounding areabefore operation and at 1wk, 1 and 3mo after operation were compared and observed, and the incidence of complications was compared between the two groups. RESULTS: There were significant differences in the improvement rate and reduction rate of visual acuity among three groups at 3mo after operation(PPPPPPPPPCONCLUSION: Phacoemulsification combined with intraocular lens implantation can relieve angle closure caused by pupillary block and lens factors, and can significantly improve the vision and reduce intraocular pressure of PACD patients with cataract, and it has small effects on postoperative macular edema with few complications.

    Purpose. To characterize functional and structural changes in a canine model of hereditary primary angle-closure glaucoma. Methods. Intraocular pressure (IOP) was evaluated with tonometry in a colony of glaucomatous dogs at 8, 15, 18, 20, and 30 months of age. Retinal function was evaluated using electroretinography (scotopic, photopic, and pattern). Examination of anterior segment structures was performed using gonioscopy and high-frequency ultrasonography (HFU). Results. A gradual rise in IOP was observed with an increase in age: 8 months, 14 mm Hg (median value); 15 months, 15.5 mm Hg; 18 months, 17.5 mm Hg; 20 months, 24 mm Hg; 30 months, 36 mm Hg. Provocative testing with mydriatic agents (tropicamide and atropine 1%) caused significant increases in IOP (35% and 50%, respectively). HFU analysis showed complete collapse of iridocorneal angles by 20 months of age. Scotopic and photopic ERG analysis did not reveal significant deficits, but pattern ERG analysis showed significantly reduced amplitudes in glaucomatous dogs (glaucoma, 3.5 ± 0.4 μV; control, 6.2 ± 0.3 μV; P = 0.004; Student's t-test). Histologic analysis revealed collapse of the iridocorneal angle, posterior bowing of the lamina cribrosa, swelling and loss of large retinal ganglion cells, increased glial reactivity, and increased thickening of the lamina cribrosa. Conclusions. Canine hereditary angle-closure glaucoma is characterized by a progressive increase in intraocular pressure, loss of optic nerve function, and retinal ganglion cell loss. PMID:19661222

Patients were treated with similar protocols of intensive medical therapy until laser peripheral iridotomy could be performed. In the event of failed medical treatment, patients at NUH only underwent laser iridoplasty. The 1-year outcomes were reviewed.Results: The demographic features of patients and presenting intraocular pressures (IOP were similar in both centers. More patients from NUH presented within 3 days of symptom onset, compared to those from SNEC (90.0% versus 71.2%, respectively (P = 0.037. The mean ± standard deviation time to break the attack was 18.2 ± 32.9 hours at SNEC and 9.80 ± 10.6 hours at NUH (P = 0.11. The mean follow up duration was 18.8 ± 14.0 months. Nineteen patients (36.5% from SNEC and six patients (22.5% from NUH developed raised IOP (P = 0.032 within 1-year of the attack. Of these, glaucomatous optic neuropathy developed in thirteen patients (68.4% from SNEC and all six patients (100% from NUH. At final review, the mean IOP of the APAC eye was 14.8 ± 4.3 mmHg from SNEC and 13.4 ± 3.0 mmHg from NUH. There was no significant difference in final visual acuity or IOP between both groups.Conclusion: Treatment strategies in both centers were effective in aborting an APAC attack. The development of raised IOP appears to be associated with a longer

    Objective To determine longitudinal changes in angle configuration in the eyes of primary angle-closure suspects (PACS) treated by laser peripheral iridotomy (LPI) and in untreated fellow eyes. Design Longitudinal cohort study. Participants Primary angle-closure suspects aged 50 to 70 years were enrolled in a randomized, controlled clinical trial. Methods Each participant was treated by LPI in 1 randomly selected eye, with the fellow eye serving as a control. Angle width was assessed in a masked fashion using gonioscopy and anterior segment optical coherence tomography (AS-OCT) before and at 2 weeks, 6 months, and 18 months after LPI. Main Outcome Measures Angle width in degrees was calculated from Shaffer grades assessed under static gonioscopy. Angle configuration was also evaluated using angle opening distance (AOD250, AOD500, AOD750), trabecular-iris space area (TISA500, TISA750), and angle recess area (ARA) measured in AS-OCT images. Results No significant difference was found in baseline measures of angle configuration between treated and untreated eyes. At 2 weeks after LPI, the drainage angle on gonioscopy widened from a mean of 13.5° at baseline to a mean of 25.7° in treated eyes, which was also confirmed by significant increases in all AS-OCT angle width measures (Pgonioscopy (P = 0.18), AOD250 (P = 0.167) and ARA (P = 0.83). In untreated eyes, angle width consistently decreased across all follow-up visits after LPI, with a more rapid longitudinal decrease compared with treated eyes (P values for all variables ≤0.003). The annual rate of change in angle width was equivalent to 1.2°/year (95% confidence interval [CI], 0.8–1.6) in treated eyes and 1.6°/year (95% CI, 1.3–2.0) in untreated eyes (P<0.001). Conclusions Angle width of treated eyes increased markedly after LPI, remained stable for 6 months, and then decreased significantly by 18 months after LPI. Untreated eyes experienced a more consistent and rapid decrease in angle width over the

Best-corrected visual acuity (BCVA, intraocular pressure (IOP, the main complications following surgery, and indentation gonioscopy and angle parameters measured using UBM were documented preoperatively and postoperatively.RESULTS:The improvement in BCVA in the phacoemulsification group was significantly greater than in the combined group (P<0.05. IOP in the phacoemulsification group was slightly higher than in the combined group following 1wk of follow-up (P<0.05, whereas there was no significant difference between the two groups at the latter follow-up (P>0.05. Phacoemulsification alone resulted in a slight increase in the trabecular ciliary processes distance compared with the combined surgery (P<0.05, whereas the other angle parameters showed no significant difference between the groups. Complications in combined group were greater than phacoemulsification only group.CONCLUSION:Both surgeries effectively opened the drainage angle and deepened the anterior chamber, and IOP was well controlled postoperatively. However, phacoemulsification showed better efficacy in improving visual function and showed reduced complications following surgery.

    To report air pressure-induced corneal deformation and iridocornea contact in eyes with primary angle closure (PAC) during intraocular pressure (IOP) measurement performed using a novel noncontact tonometer. A single case report. We report a patient with bilateral angle closure. One eye had acute PAC and the other had PAC. The latter was evaluated by the movements of the cornea and iris during IOP measurement using a noncontact tonometer. During the examination, the corneal endothelium and the iris came into contact at the mid-peripheral pupillary area in the left eye with PAC during the corneal reaction to an air puff. In contrast, the corneal endothelium in the pupillary area did not come into contact with the iris. Although we observed only 1 case and there could be limitations in its interpretation, IOP measurements using a noncontact tonometer may create mechanical stress on the corneal endothelium in eyes with PAC with a very shallow anterior chamber.

    Primary angle-closure glaucoma is a leading cause of irreversible blindness worldwide. In early-stage disease, intraocular pressure is raised without visual loss. Because the crystalline lens has a major mechanistic role, lens extraction might be a useful initial treatment. From Jan 8, 2009, to Dec 28, 2011, we enrolled patients from 30 hospital eye services in five countries. Randomisation was done by a web-based application. Patients were assigned to undergo clear-lens extraction or receive standard care with laser peripheral iridotomy and topical medical treatment. Eligible patients were aged 50 years or older, did not have cataracts, and had newly diagnosed primary angle closure with intraocular pressure 30 mm Hg or greater or primary angle-closure glaucoma. The co-primary endpoints were patient-reported health status, intraocular pressure, and incremental cost-effectiveness ratio per quality-adjusted life-year gained 36 months after treatment. Analysis was by intention to treat. This study is registered, number ISRCTN44464607. Of 419 participants enrolled, 155 had primary angle closure and 263 primary angle-closure glaucoma. 208 were assigned to clear-lens extraction and 211 to standard care, of whom 351 (84%) had complete data on health status and 366 (87%) on intraocular pressure. The mean health status score (0·87 [SD 0·12]), assessed with the European Quality of Life-5 Dimensions questionnaire, was 0·052 higher (95% CI 0·015-0·088, p=0·005) and mean intraocular pressure (16·6 [SD 3·5] mm Hg) 1·18 mm Hg lower (95% CI -1·99 to -0·38, p=0·004) after clear-lens extraction than after standard care. The incremental cost-effectiveness ratio was £14 284 for initial lens extraction versus standard care. Irreversible loss of vision occurred in one participant who underwent clear-lens extraction and three who received standard care. No patients had serious adverse events. Clear-lens extraction showed greater efficacy and was more cost-effective than

    To assess the efficacy and complications of Nd: YAG laser iridotomy in patients with intermittent (sub-acute) angle closure glaucoma. Twenty-five eyes of twenty-three patients with periodic (intermittent) angle closure, selected in outpatient department, were kept on pilocarpine until YAG laser iridotomy was performed. After YAG laser iridotomy oral acetazolamide and topical dexamethasone was used to control post laser rise of IOP and inflammation respectively. Patency of iridotomy was confirmed and intra-ocular pressure was measured one hour after the procedure. Immediate complication, if any, was noted. Follow-up was done for six months. Prophylactic laser iridotomy was done in fellow eye with occludable angle. Levene's test for equality of variance and t-test for equality of means were used for statistical analysis. This study revealed a significant difference in IOP before and after YAG laser iridotomy (p = .002). Complete follow-up of 6 months was possible in 25 eyes of 23 subjects. After YAG Laser iridotomy, 21 (84%) eyes showed negative provocative test, intraocular pressure below 19mm Hg without medication and anterior chamber angle no more occludable and were labeled successful. Iridotomy remained patent in 96% of eyes. Iridotomy failed to reduce IOP in 4 (16%) eyes. The complications were minimal and transient. (author)

    To assess the correlations between retinal nerve fiber layer (RNFL) thickness measured with scanning laser polarimetry and visual field (VF) sensitivity in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). Prospective, comparative, observational cases series. Fifty patients with POAG and 56 patients with PACG were examined using scanning laser polarimetry with variable corneal compensation (GDx VCC; Laser Diagnostic Technologies, Inc.) and Humphrey VF analyzer (Carl Zeiss Meditec, Inc.) between August 2005 and July 2006 at Taipei Veterans General Hospital. Correlations between RNFL thickness and VF sensitivity, expressed as mean sensitivity in both decibel and 1/Lambert scales, were estimated by the Spearman rank correlation coefficient (r(s)) and multivariate median regression models (pseudo R(2)). The correlations were determined globally and for 6 RNFL sectors and their corresponding VF regions. The correlation between RNFL thickness and mean sensitivity (in decibels) was weaker in the PACG group (r(s) = 0.38; P = .004; pseudo R(2) = 0.17) than in the POAG group (r(s) = 0.51; P polarimetry. Compared with eyes with POAG, fewer RNFL sectors have significant structure-function correlations in eyes with PACG. Copyright 2010 Elsevier Inc. All rights reserved.

    Full Text Available Purpose: To report an unusual case of ectopia lentis and angle closure in a patient with chronic eye rubbing. Methods: A 57-year-old male with a history of poorly controlled atopic dermatitis presented with right eye pain, decreased vision, and an intraocular pressure (IOP of 55 mm Hg. He had no past history of ocular disease and no reported history of trauma. He did report a history of chronic eye rubbing. Results: Best corrected visual acuity was hand motions. The examination revealed severe atopic keratoconjunctivitis in both eyes, microcystic corneal edema of the right eye, and 2+ nuclear sclerosis in both eyes. Gonioscopy showed no visible angle structures OD and an open angle OS. Topical and oral IOP-lowering medications and a laser iridotomy were unsuccessful at lowering IOP. He was taken to the operating room for a lensectomy and was found to have 9 clock hours of zonular dehiscence and a dislocated lens. After lensectomy, the IOP improved to 9 mm Hg on postoperative day 1. A follow-up examination at 2 weeks showed improved acuity to 20/150 with a pinhole and an IOP of 10 mm Hg. A dilated examination OS did not reveal significant phacodonesis, and the patient was referred for a possible sutured sulcus lens or anterior chamber intraocular lens. Conclusions: It is important for the provider to consider ectopia lentis in the differential for patients with pupillary block angle closure. For patients with atopic disease, one should be aware that eye rubbing may be a cause of zonular dehiscence, even in the absence of reported trauma or prior intraocular surgery.

    Purpose To assess the correlations between retinal nerve fiber layer (RNFL) thickness measured with scanning laser polarimetry (SLP) and visual field (VF) sensitivity in primary open angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). Design Prospective, comparative, observational cases series Methods Fifty patients with POAG and 56 with PACG were examined using SLP with variable corneal compensation (GDx VCC) and Humphrey VF analyzer between August 2005 and July 2006 at Taipei Veterans General Hospital. Correlations between RNFL thickness and VF sensitivity, expressed as mean sensitivity (MS) in both decibel (dB) and 1/Lambert (L) scales, were estimated by Spearman's rank correlation coefficient (rs) and multivariate median regression models (pseudo R2). The correlations were determined globally and for six RNFL sectors and their corresponding VF regions. Results The correlation between RNFL thickness and MS (in dB) was weaker in the PACG group (rs = 0.38, P = 0.004, pseudo R2 = 0.17) than in the POAG group (rs = 0.51, P <0.001, pseudo R2 = 0.31), but the difference in the magnitude of correlation was not significant (P = 0.42).With Bonferroni correction, the structure-function correlation was significant in the superotemporal (rs = 0.62), superonasal (rs = 0.56), inferonasal (rs = 0.53), and inferotemporal (rs = 0.50) sectors in the POAG group (all P <0.001), while it was significant only in the superotemporal (rs = 0.53) and inferotemporal (rs = 0.48) sectors in the PACG group (both P <0.001). The results were similar when MS was expressed as 1/L scale. Conclusions Both POAG and PACG eyes had moderate structure-function correlations using SLP. Compared to eyes with POAG, fewer RNFL sectors have significant structure-function correlations in eyes with PACG. PMID:20202618

  19. Primary Angle Closure and Sequence Variants within MicroRNA Binding Sites of Genes Involved in Eye Development.

    Haihong Shi

    Full Text Available The formation of primary angle closure (PAC and primary angle closure glaucoma (PACG is regulated by a tissue remodeling pathway that plays a critical role in eye development. MicroRNAs (miRNAs are powerful gene expression regulators and may exert their effects on tissue remodeling genes. This study investigated the associations between gene variants (single-nucleotide polymorphism, SNP in miRNA binding sites in the 3'-UTR region of genes involved in eye development and PAC.The sample consisted of 232 PAC subjects and 306 controls obtained from a population-based cohort in the Funing District of Jiangsu, China. The markers include 9 SNPs in the COL11A1, PCMTD1, ZNRF3, MTHFR, and ALPPL2 genes respectively. SNP genotyping was performed with a TaqMan-MGB probe using an RT-PCR system.Of the 9 SNPs studied, the frequency of the minor A allele of COL11A1 rs1031820 was higher in the PAC group than in the control group in allele analysis (p = 0.047. The genotype analysis indicated that MTHFR rs1537514 is marginally associated with PAC (p = 0.014. The CC genotype of rs1537514 was present solely in the PAC group. However, the differences lost significance after Bonferroni correction.Our study reveals a possible association of COL11A1 and MTHFR with PAC in the Han Chinese population. These results will contribute to an improved understanding of the genetic basis of PACG.

    Full Text Available Purpose: To report the prevalence of plateau iris in patients with primary angle closure glaucoma (PACG, in North India. Materials and Methods: The patients with PACG, attending the glaucoma services at a tertiary care center in North India were included in the study. All patients had undergone Nd-YAG laser peripheral iridotomy at least four weeks prior to inclusion in the study. Four weeks prior to inclusion in the study, none of the patients had used pilocarpine. Ultrasound Biomicroscopy (UBM images were qualitatively evaluated and plateau iris configuration was defined in an eye if the following criteria were fulfilled in two or more quadrants: anteriorly directed ciliary process supporting the peripheral iris, steep rise of iris root from its point of insertion followed by a downward angulation from the corneoscleral wall, absent ciliary sulcus, and iridotrabecular contact in the same quadrant. Results: One hundred and one eyes were included in the study. There were 63 (62.4% females and 38 (37.6% males. The mean age of the patients was 57.8 ± 9.5 years (range: 42 to 78 years. The mean axial length in the study population was 22.2 ± 1.1 mm. The mean spherical equivalent refraction was 0.06 ± 1.12 D. The mean intraocular pressure was 18.5 ± 4.7 mmHg (range: 12 - 24 mmHg. Twenty-nine (28.7% subjects were diagnosed with plateau iris on the basis of above-defined criteria. Of the 29 eyes, 18 (62.1% subjects had plateau iris in two quadrants, nine (31.03% in three quadrants, and two (6.8% had this configuration in all the four quadrants. Conclusions: Approximately 30% of the eyes with PACG had plateau iris on UBM. Plateau iris was very often the cause for residual angle closure following laser peripheral iridotomy in Indian eyes with PACG.

    Full Text Available Using voxel-wise degree centrality (DC, as measured by resting-state fMRI, we aimed to study alterations in the brain functional networks in patients with primary angle-closure glaucoma (PACG and to reveal the plastic trajectories of surgery.A total of 23 preoperative PACG patients (49.48 ± 14.37 years old were recruited to undergo a resting-state fMRI scan, and 9 of them were rescanned 3 months after surgery. All PACG patients underwent a complete ophthalmologic examination, including intraocular pressure (IOP, retinal nerve fiber layer (RNFL thickness, vertical cup to disc ratio (V C/D, and average cup to disc ratio (A C/D. Another 23 gender- and age-matched healthy controls (48.18 ± 9.40 years old underwent scanning once for comparison. The group difference in DC was calculated in each voxel, and the correlations between the DC value and each of the clinical variables were analyzed in the PACG patients.Preoperative PACG (pre-PACG patients showed significantly decreased DC in the bilateral visual cortices but increased DC in the left anterior cingulate cortex (ACC and caudate (p < 0.05, corrected compared with the controls. Statistical analysis showed a significantly negative correlation between DC in the bilateral visual cortices and the IOP score and between DC in the anterior cingulate cortex (ACC and both the A C/D and V C/D scores in the pre-PACG patients. Three months after surgery, these postoperative PACG (post-PACG patients showed a significantly increased DC in both the bilateral visual cortices and the left precentral gyrus compared with the pre-PACG patients.Our results suggest that PACG may contribute to decreased functional centrality in the visual system and to increased degree centrality in cognition-emotional processing regions.

    Full Text Available Purpose: To compare, clinically and biometrically, affected and fellow acute primary angle-closure (APAC eyes and glaucomatous eyes with narrow angle (NA. Methods: Comparative case series; 30 patients with APAC and 27 glaucomatous patients with NA were evaluated. Keratometry (K, central corneal thickness (CCT, lens thickness (LT, axial length (AL and anterior chamber depth (ACD were measured. Parameters defined as lens posisiton (LP and relative lens position (RLP were calculated. Results: Biometric difference between APAC-affected and fellow eyes was found only in LP (P=0.046. When fellow eyes were compared to glaucomatous eyes with NA, differences were found in ACD (P=0.009, AL (P=0.010, and LT/AL (P=0.005. The comparison between APAC-affected and glaucomatous eyes with NA showed significant differences in almost all biometric parameters, except for LT (P=0.148 and RLP (P=0.374. We found that the logistic regression model (LRM, built with three parameters (K, CCT and LT/AL, higher than 0.334 could be a reasonable instrument to differentiate APAC eyes from glaucomatous eyes with NA. Conclusions: This study showed that APAC-affected and fellow eyes have similar biometric features, and glaucomatous eyes with NA have a less crowded anterior segment. The LRM built showed promising results in distinguishing APAC from glaucomatous eyes with NA.

    Purpose. To describe the characteristics of the iridocorneal angle using ultrasound biomicroscopy (UBM) in Chinese people classified gonioscopically as having suspected primary angle-closure (PACS) glaucoma. Methods. PACS were defined as not having visible posterior (usually pigmented) trabecular meshwork in two or more quadrants examined by static gonioscopy. The PACS and 1 of 10 those who did not meet this criterion were identified from a population-based survey. Iridotrabecular meshwork contact (ITC) was identified and further classified into low and high, according to standard UBM images. Those with high ITC were further classified according the configuration of ITC: B-type, with contiguous ITC from the base of the angle, and S-type, with ITC localized to the region of Schwalbe's line. Results. ITC was identified in 78.6% of the superior, 40.2% of the nasal, 59.8% of the inferior, and 25.6% of the temporal quadrants in the PACS (n = 117). These proportions were 43.9%, 15.8%, 29.8%, and 14.0% in the controls (n = 57), respectively. About two thirds of the eyes with ITC were classified as high. In those with high ITC, the number with B- and S-type ITC was very similar. The proportions of any high ITCs increased substantially from 15.4% in those with Shaffer angle grade 4 and 45.0% in grade 3, to 71.0% in grade 2, 70.2% in grade 1, and 86.4% in grade 0. Conclusions. More ITC is identified on UBM imaging than by gonioscopy. Careful consideration should be given to the assessment modality regarded as the reference standard in defining anatomic risk factors for glaucomatous visual loss and the need for treatment.

    Full Text Available Several dog breeds are susceptible to developing primary angle closure glaucoma (PACG, which suggests a genetic basis for the disease. We have identified a four-generation Basset Hound pedigree with characteristic autosomal recessive PACG that closely recapitulates PACG in humans. Our aim is to utilize gene mapping and whole exome sequencing approaches to identify PACG-causing sequence variants in the Basset. Extensive clinical phenotyping of all pedigree members was conducted. SNP-chip genotyping was carried out in 9 affected and 15 unaffected pedigree members. Two-point and multipoint linkage analyses of genome-wide SNP data were performed using Superlink-Online SNP-1.1 and a locus was mapped to chromosome 19q with a maximum LOD score of 3.24. The locus contains 12 Ensemble predicted canine genes and is syntenic to a region on chromosome 2 in the human genome. Using exome-sequencing analysis, a possibly damaging, non-synonymous variant in the gene Nebulin (NEB was found to segregate with PACG which alters a phylogenetically conserved Lysine residue. The association of this variants with PACG was confirmed in a secondary cohort of unrelated Basset Hounds (p = 3.4 × 10-4, OR = 15.3 for homozygosity. Nebulin, a protein that promotes the contractile function of sarcomeres, was found to be prominently expressed in the ciliary muscles of the anterior segment. Our findings may provide insight into the molecular mechanisms that underlie PACG. The phenotypic similarities of disease presentation in dogs and humans may enable the translation of findings made in this study to patients with PACG.

    Full Text Available To compare changes in anterior segment parameters under light and dark (light-to-dark conditions among eyes with chronic primary angle-closure glaucoma (CPACG, fellow eyes with confirmed or suspect primary angle-closure (PAC or PACS, and age-matched healthy eyes.Consecutive patients with CPACG in one eye and PAC/PACS in the fellow eye, as well as age-matched healthy subjects were recruited. Anterior segment optical coherence tomography measurements were conducted under light and dark conditions, and anterior chamber, lens, and iris parameters compared. Demographic and biometric factors associated with light-to-dark change in iris area were analyzed by linear regression.Fifty-seven patients (mean age 59.6±8.9 years and 30 normal subjects matched for age (60.6±9.3 years and sex ratio were recruited. In regards to differences under light-to-dark conditions, angle opening distance at 500 μm (AOD500μm and iris area during light-to-dark transition were smaller in CPACG eyes than fellow PACS/PAC eyes and normal eyes (P<0.017. Pupil diameter change was largest in normal eyes, and larger in PACS/PAC eyes than CPACG eyes (P<0.017. There was an average reduction of 0.145 mm2 in iris area for each millimeter of pupil diameter increase in CPACG eyes, 0.161 mm2 in fellow PAC/PACS eyes, and 0.165 mm2 in normal eyes. Larger iris curvature in the dark and diagnosis of PACG were significantly associated with less light-to-dark iris area changes.Dynamic changes in iris parameters with light-to-dark transition differed significantly among CPACG eyes, fellow PAC/PACS eyes, and normal eyes. Greater iris curvature under dark conditions was correlated with reduced light-to-dark change in iris area and pupil diameter, which may contribute to disease progression.

    Background Argon laser peripheral iridoplasty (ALPI) is proved to be effective in lowering intraocular pressure (IOP) of patients with mild acute primary angle closure (APAC).It is unclear whether this laser treatment is equally efficient in managing patients with severe APAC.This study aimed to evaluate the IOP-lowering efficacy of ALPI and laser peripheral iridotomy (LPI) on patients with refractory APAC,who have previously responded poorly to intensive medical therapy.Methods Thirty-six patients (8 men and 28 women) were identified as medically refractory APAC,who still had ocular pain,red eye,hazy cornea,closed anterior chamber (AC) angle,and IOP of not less than 21 mmHg after two days or more of anti-glaucoma medication.All enrolled patients underwent ophthalmologic examinations including measurement of visual acuity (VA),best corrected VA (BCVA),IOP,biomicroscopy,and gonioscopy followed by ALPI immediately in the APAC eye and LPI in both eyes.Results All patients were affected unilaterally,with average age of (54.6±11.7) (range,37.0-75.0) years old.The mean IOP value of the affected eyes dropped from (31.6±7.7) (range,21.0-39.0) mmHg at enrollment to (18.4±8.7) (range,10.0-27.0) mmHg 2 hours after ALPI.At follow-up day 7,the mean IOP value maintained at (14.8±4.2) (range,9.0-21.0)mmHg,which was significantly different (P=0.000) compared with baseline.The average decrease of IOP in the APAC eyes was (16.8±7.4) (range,12.0-21.0) mmHg.At follow-up three years later,the mean IOP of the APAC eyes stabilized at (16.3±3.2) (range,9.0-20.0) mmHg with at least 180° of AC angle opened.Conclusion ALPI and LPI lower the IOP of medically refractory cases of APAC though they have responded poorly to anti-glaucoma medication.

    Full Text Available To determine the factors associated with retinal nerve fiber layer (RNFL loss in eyes with acute primary angle-closure (APAC, particularly focusing on the influence of the change in the anterior lamina cribrosa surface depth (LCD.After the initial presentation, 30 eyes with unilateral APAC were followed up at the following specific time points over a 12-month period: 1 week, 1~2 months, 2~3 months, 5~6 months, and 11~12 months. These follow-ups involved intraocular pressure measurements, enhanced depth-imaging spectral-domain optical coherence tomography (SD-OCT scanning of the optic disc, and measurements of the circumpapillary RNFL thickness. The prelaminar tissue thickness (PLT and LCD were determined in the SD-OCT images obtained at each follow-up visit.Repeated measures analysis of variance revealed a significant pattern of decrease in the global RNFL thickness, PLT, and LCD (all p<0.001. The global RNFL thickness decreased continuously throughout the follow-up period, while the PLT decreased until 5~6 months and did not change thereafter. The LCD reduced until 2~3 months and then also remained steady. Multivariable regression analysis revealed that symptoms with a longer duration before receiving laser peripheral iridotomy (LI (p = 0.049 and a larger LCD reduction (p = 0.034 were significant factors associated with the conversion to an abnormal RNFL thickness defined using OCT normative data.Early short-term decreases in the PLT and LCD and overall long-term decrease in the peripapillary RNFL were observed during a 12-month follow-up after an APAC episode. A longer duration of symptoms before receiving LI treatment and larger LCD reduction during follow-up were associated with the progressive RNFL loss. The LCD reduction may indicate a prior presence of significant pressure-induced stress that had been imposed on the optic nerve head at the time of APAC episode. Glaucomatous progression should be suspected in eyes showing LCD reduction

    Objective: To evaluate the rate of blindness caused by primary angle closure glaucoma (PACG) in Chinese population of more than 40 years old, and to explore the effectiveness of a prevention and treatment system on PACG. Methods: We searched the databases of Pubmed, ScienceDirect, Springer Link, CNKI and Wanfang Data and collected all the original studies of the prevalence and blindness of angle closure glaucoma in China. The population was limited to over 40 years old. The research site was limited to the community-based, while the published time was not limited. Two researchers completed the literature search, data extraction and methodological quality assessment independently, with same criteria. Meta analysis was performed using R software. Results: Five papers were included in this study finally. A total of 26 437 cases of natural population over the age of 40 were observed, and 306 cases of angle closure glaucoma were found, of which 113 cases had binocular or monocular blindness caused by PACG. The random effect model meta-analysis results showed that the overall blindness rate was 38.3% [95% CI (28.1%, 49.6%)]. In Beijing, where the prevention and treatment system was well established, the blindness rate was far lower than that in the areas where the system was poorly established. Compared with the past, the blindness rate caused by PACG in Beijing decreased sharply. Conclusions: The rate of blindness caused by PACG is still high in the mainland of China. The prevention and treatment system is effective and worth promoting. (Chin J Ophthalmol, 2017, 53: 373 - 377) .

    Angle-closure glaucoma is a leading cause of irreversible blindness in the world. Treatment is aimed at opening the anterior chamber angle and lowering the IOP with medical and/or surgical treatment (e.g. trabeculectomy, lens extraction). Laser iridotomy works by eliminating pupillary block and widens the anterior chamber angle in the majority of patients. When laser iridotomy fails to open the anterior chamber angle, laser iridoplasty may be recommended as one of the options in current standard treatment for angle-closure. Laser peripheral iridoplasty works by shrinking and pulling the peripheral iris tissue away from the trabecular meshwork. Laser peripheral iridoplasty can be used for crisis of acute angle-closure and also in non-acute situations.   To assess the effectiveness of laser peripheral iridoplasty in the treatment of narrow angles (i.e. primary angle-closure suspect), primary angle-closure (PAC) or primary angle-closure glaucoma (PACG) in non-acute situations when compared with any other intervention. In this review, angle-closure will refer to patients with narrow angles (PACs), PAC and PACG. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2011, Issue 12), MEDLINE (January 1950 to January 2012), EMBASE (January 1980 to January 2012), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to January 2012), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 5 January 2012. We included only randomised controlled trials (RCTs) in this review. Patients with narrow angles, PAC or PACG were eligible. We excluded studies that included only patients with acute presentations

    To investigate the clinical, anatomical, and patient-reported outcomes of phacoemulsification (PE) with intraocular lens implantation performed to treat primary angle closure (PAC) and primary angle-closure glaucoma (PACG). Patients were evaluated at baseline and at 6 months after PE. The examination included visual acuity, intraocular pressure (IOP), visual field, optic nerve head, endothelial cell count (ECC), aqueous depth, and ocular biometric parameters. Patient-reported visual function and health status were assessed. Coprimary outcome measures were IOP changes, angle widening, and patient-reported visual function; secondary outcome measures were visual acuity changes, use of IOP-lowering medications, and complications. Univariate and multivariate analyses were performed to determine the predictors of IOP change. Thirty-nine cases were identified, and postoperative data were analyzed for 59 eyes, 39 with PACG and 20 with PAC. Globally, PE resulted in a mean reduction in IOP of -6.33 mm Hg (95% CI, -8.64 to -4.01, P <.001). Aqueous depth and angle measurements improved ( P <.01), whereas ECC significantly decreased ( P <.001). Both corrected and uncorrected visual acuity improved ( P <.01). The EQ visual analog scale did not change ( P =.16), but VFQ-25 improved ( P <.01). The IOP-lowering effect of PE was greater in the PACG compared to the PAC group ( P =.04). In both groups, preoperative IOP was the most significant predictor of IOP change ( P <.01). No sight-threatening complications were recorded. Our data support the usefulness of PE in lowering the IOP in patients with PAC and PACG. Although PE resulted in several anatomical and patient-reported visual improvements, we observe that a marked decrease in ECC should be carefully weighed before surgery.

    This study aimed to evaluate differences in iris gene expression profiles between primary angle closure glaucoma (PACG) and primary open angle glaucoma (POAG) and their interaction with biometric characteristics. Prospective study. Thirty-five subjects with PACG and thirty-three subjects with POAG who required trabeculectomy were enrolled at the Singapore National Eye Centre, Singapore. Iris specimens, obtained by iridectomy, were analysed by real-time polymerase chain reaction for expression of type I collagen, vascular endothelial growth factor (VEGF)-A, -B and -C, as well as VEGF receptors (VEGFRs) 1 and 2. Anterior segment optical coherence tomography (ASOCT) imaging for biometric parameters, including anterior chamber depth (ACD), anterior chamber volume (ACV) and lens vault (LV), was also performed pre-operatively. Relative mRNA levels between PACG and POAG irises, biometric measurements, discriminant analyses using genes and biometric parameters. COL1A1, VEGFB, VEGFC and VEGFR2 mRNA expression was higher in PACG compared to POAG irises. LV, ACD and ACV were significantly different between the two subgroups. Discriminant analyses based on gene expression, biometric parameters or a combination of both gene expression and biometrics (LV and ACV), correctly classified 94.1%, 85.3% and 94.1% of the original PACG and POAG cases, respectively. The discriminant function combining genes and biometrics demonstrated the highest accuracy in cross-validated classification of the two glaucoma subtypes. Distinct iris gene expression supports the pathophysiological differences that exist between PACG and POAG. Biometric parameters can combine with iris gene expression to more accurately define PACG from POAG. © 2016 The Authors.

    Objective To investigate the cost-effectiveness of early lens extraction with intraocular lens implantation for the treatment of primary angle closure glaucoma (PACG) compared to standard care. Design Cost-effectiveness analysis alongside a multicentre pragmatic two-arm randomised controlled trial. Patients were followed-up for 36 months, and data on health service usage and health state utility were collected and analysed within the trial time horizon. A Markov model was developed to extrapolate the results over a 5-year and 10-year time horizon. Setting 22 hospital eye services in the UK. Population Males and females aged 50 years or over with newly diagnosed PACG or primary angle closure (PAC). Interventions Lens extraction compared to standard care (ie, laser iridotomy followed by medical therapy and glaucoma surgery). Outcome measures Costs of primary and secondary healthcare usage (UK NHS perspective), quality-adjusted life years (QALYs) and the incremental cost-effectiveness ratio (ICER) for lens extraction versus standard care. Results The mean age of participants was 67.5 (8.42), 57.5% were women, 44.6% had both eyes eligible, 1.4% were of Asian ethnicity and 35.4% had PAC. The mean health service costs were higher in patients randomised to lens extraction: £2467 vs £1486. The mean adjusted QALYs were also higher with early lens extraction: 2.602 vs 2.533. The ICER for lens extraction versus standard care was £14 284 per QALY gained at three years. Modelling suggests that the ICER may drop to £7090 per QALY gained by 5 years and that lens extraction may be cost saving by 10 years. Our results are generally robust to changes in the key input parameters and assumptions. Conclusions We find that lens extraction has a 67–89% chance of being cost-effective at 3 years and that it may be cost saving by 10 years. Trial registration number ISRCTN44464607; Results.

    Glaucoma is the leading cause of irreversible blindness. Although primary open-angle glaucoma is more common, primary angle-closure glaucoma (PACG) is more likely to result in irreversible blindness. By 2020, 5·3 million people worldwide will be blind because of PACG. The current standard care for PACG is a stepped approach of a combination of laser iridotomy surgery (to open the drainage angle) and medical treatment (to reduce intraocular pressure). If these treatments fail, glaucoma surgery (eg, trabeculectomy) is indicated. It has been proposed that, because the lens of the eye plays a major role in the mechanisms leading to PACG, early clear lens extraction will improve glaucoma control by opening the drainage angle. This procedure might reduce the need for drugs and glaucoma surgery, maintain good visual acuity, and improve quality of life compared with standard care.EAGLE aims to evaluate whether early lens extraction improves patient-reported, clinical outcomes, and cost-effectiveness, compared with standard care. EAGLE is a multicentre pragmatic randomized trial. All people presenting to the recruitment centres in the UK and east Asia with newly diagnosed PACG and who are at least 50 years old are eligible.The primary outcomes are EQ-5D, intraocular pressure, and incremental cost per quality adjusted life year (QALY) gained. Other outcomes are: vision and glaucoma-specific patient-reported outcomes, visual acuity, visual field, angle closure, number of medications, additional surgery (e.g., trabeculectomy), costs to the health services and patients, and adverse events.A single main analysis will be done at the end of the trial, after three years of follow-up. The analysis will be based on all participants as randomized (intention to treat). 400 participants (200 in each group) will be recruited, to have 90% power at 5% significance level to detect a difference in EQ-5D score between the two groups of 0·05, and a mean difference in intraocular pressure of

Patients with primary narrow angle may be classified as a primary angle closure suspect (PACS, or as having primary angle closure (PAC or primary angle closure glaucoma (PACG. 23.9% of patients with primary angle closure disease are in India, which highlights the importance of understanding the disease, its natural history, and its underlying pathophysiology, so that we may try to establish effective methods of treatment and preventative measures to delay, or even arrest, disease progression, thereby reducing visual morbidity. AIM To determine the lens thickness using A-scan biometry and its significance in various stages of angle closure disease. MATERIALS AND METHODS Patients attending outpatient department at Minto Ophthalmic Hospital between October 2013 to May 2015 were screened for angle closure disease and subsequently evaluated at glaucoma department. In our study, lens thickness showed a direct correlation with shallowing of the anterior chamber by determining the LT/ ACD ratio. A decrease in anterior chamber depth is proportional to the narrowing of the angle which contributes to the progression of the angle closure disease from just apposition to occlusion enhancing the risk for optic nerve damage and visual field loss. Hence, if the lens thickness values are assessed earlier in the disease process, appropriate intervention can be planned. CONCLUSION Determination of lens changes along with anterior chamber depth and axial length morphometrically can aid in early detection of angle closure. The role of lens extraction for PACG is a subject of increased interest. Lens extraction promotes the benefits of anatomical opening of the angle, IOP reduction and improved vision. This potential intervention may be one among the armamentarium of approaches for PACG. Among the current treatment modalities

    PLEKHA7, a gene recently associated with primary angle closure glaucoma (PACG), encodes an apical junctional protein expressed in components of the blood aqueous barrier (BAB). We found that PLEKHA7 is down-regulated in lens epithelial cells and in iris tissue of PACG patients. PLEKHA7 expression also correlated with the C risk allele of the sentinel SNP rs11024102 with the risk allele carrier groups having significantly reduced PLEKHA7 levels compared to non-risk allele carriers. Silencing of PLEKHA7 in human immortalized non-pigmented ciliary epithelium (h-iNPCE) and primary trabecular meshwork cells, which are intimately linked to BAB and aqueous humor outflow respectively, affected actin cytoskeleton organization. PLEKHA7 specifically interacts with GTP-bound Rac1 and Cdc42, but not RhoA, and the activation status of the two small GTPases is linked to PLEKHA7 expression levels. PLEKHA7 stimulates Rac1 and Cdc42 GTP hydrolysis, without affecting nucleotide exchange, identifying PLEKHA7 as a novel Rac1/Cdc42 GAP. Consistent with the regulatory role of Rac1 and Cdc42 in maintaining the tight junction permeability, silencing of PLEKHA7 compromises the paracellular barrier between h-iNPCE cells. Thus, downregulation of PLEKHA7 in PACG may affect BAB integrity and aqueous humor outflow via its Rac1/Cdc42 GAP activity, thereby contributing to disease etiology. © The Author 2017.

The ALFF method was used to assess the local features of spontaneous brain activity. The correlation analysis was used to explore the relationships between the observed mean ALFF signal values of the different areas in PACG patients and the thickness of the retinal nerve fiber layer (RNFL. Results: Compared with the healthy subjects, patients with PACG had significant lower ALFF areas in the left precentral gyrus, bilateral middle frontal gyrus, bilateral superior frontal gyrus, right precuneus, and right angular gyrus, and higher areas in the right precentral gyrus. In the PACG group, there were significant negative correlations between the mean ALFF signal value of the right middle frontal gyrus and the left mean RNFL thickness (r=-0.487, P=0.033, and between the mean ALFF signal value of the left middle frontal gyrus and the right mean RNFL thickness (r=-0.504, P=0.020.

    A subluxation or dislocation of the intraocular lens (IOL) is a well-known complication after cataract surgery in patients with pseudoexfoliation syndrome (PEX). Capsular tension rings (CTR) are frequently used to prevent postoperative complications caused by zonular weakness. Here we present a series of 7 cases, 2 with intermittent and 5 with acute angle closure caused by a combination of PEX-associated zonular weakness and a resulting unstable capsular bag-CTR-IOL complex. We describe the typical clinical course with elevated intraocular pressure, myopic shift, and shallowing of the anterior chamber in 7 patients with a new type of secondary angle closure. The diagnostic challenges and treatment options are discussed in detail. In all cases, the mechanism of angle closure identified by ultrasound biomicroscopy was an anterior dislocation of the peripheral iris by the capsular bag-CTR-IOL complex. The IOL was removed together with the capsular bag and the CTR and replaced by an iris-fixated IOL in all cases. We present a new type of secondary angle closure caused by an anterior dislocated capsular bag-CTR-IOL complex. The cause of both, this atypical presentation and the ineffectiveness of the laser peripheral iridotomy is the large diameter CTR. Therefore CTR implantation might also be the source of late postoperative complications. If a secondary angle closure associated with PEX and unstable capsular bag-CTR-IOL complex is encountered, IOL explantation and replacement by an iris-fixated IOL is a simple and effective treatment option.

    Full Text Available BACKGROUND Angle closure is characterised by apposition of the peripheral iris against the trabecular meshwork resulting in obstruction of aqueous outflow. Acute angle-closure glaucoma is characterised by pain, redness and blurred vision. The pain is typically a severe deep ache that follows the trigeminal distribution and maybe associated with nausea, vomiting, bradycardia and profuse sweating. The blurred vision, which is typically marked maybe caused by stretching of the corneal lamellae initially and later oedema of the cornea as well as a direct effect of the IOP on the optic nerve head. The modifications in corneal endothelial cell density after a crisis of angle-closure glaucoma is being evaluated. AIMS AND OBJECTIVES The objective of the study is to assess the corneal endothelial cell count (density by specular microscopy in patients presenting with acute angle-closure glaucoma. METHODS Corneal endothelial cell counts of 20 eyes of patients with PACG with an earlier documented symptomatic acute attack unilaterally were compared with 20 fellow eyes. Evaluation of patient included visual acuity, intraocular pressure, gonioscopy, disc findings and specular microscopy. RESULTS The mean endothelial cell density was 2104 cells/mm2 in the eye with acute attack and 2615 cells/mm2 in the fellow eye. The average endothelial cell count when the duration of attack lasted more than 72 hours was 1861 cells/mm2 . CONCLUSION Corneal endothelial cell density was found to be significantly reduced in eyes following an acute attack of primary angle closure glaucoma.

    Full Text Available Purpose: Congenital ectropion uvea is a rare anomaly, which is associated with open, but dysplastic iridocorneal angles that cause childhood glaucoma. Herein, we present 3 cases of angle-closure glaucoma in children with congenital ectropion uvea. Observations: Three children were initially diagnosed with unilateral glaucoma secondary to congenital ectropion uvea at 7, 8 and 13 years of age. The three cases showed 360° of ectropion uvea and iris stromal atrophy in the affected eye. In one case, we have photographic documentation of progression to complete angle closure, which necessitated placement of a glaucoma drainage device 3 years after combined trabeculotomy and trabeculectomy. The 2 other cases, which presented as complete angle closure, also underwent glaucoma drainage device implantation. All three cases had early glaucoma drainage device encapsulation (within 4 months and required additional surgery (cycloablation or trabeculectomy. Conclusions and importance: Congenital ectropion uvea can be associated with angle-closure glaucoma, and placement of glaucoma drainage devices in all 3 of our cases showed early failure due to plate encapsulation. Glaucoma in congenital ectropion uvea requires attention to angle configuration and often requires multiple surgeries to obtain intraocular pressure control.

    Our purpose was to assess the early intraocular pressure (IOP) changes of ultralow fluence laser iridotomy using pattern scanning laser followed by neodymium:yttrium-aluminum-gamet (Nd:YAG) laser. This is a prospective interventional study. Thirty-three eyes of 33 adult Chinese primary angle-closure suspect subjects were recruited for prophylactic laser peripheral iridotomy. Sequential laser peripheral iridotomy was performed using pattern scanning laser followed by Nd:YAG laser. Visual acuity (VA) and IOP were measured before treatment, at 1 h, 1 day, 1 week, 1 month, 3 months and 6 months after laser. Laser energy used and complications were documented. Corneal endothelial cell count was examined at baseline and 6 months. Patency of the iridotomy was assessed at each follow-up visit. All subjects achieved patent iridotomy in a single session. The mean energy used was 0.335+/-0.088 J for the pattern scanning laser, and 4.767+/-5.780 mJ for the Nd:YAG laser. The total mean energy was 0.339+/-0.089 J. None of the eyes developed a clinically significant IOP spike (≥ 8 mmHg) at 1 h and 1 day after laser use. Only four eyes developed higher IOP at 1 h and all were ≤3 mmHg compared to baseline. The mean IOP was 13.8+/-2.5 mmHg at 1 h and 11.5+/-2.2 mmHg at 1 day, both were significantly lower than baseline (15.8+/-2.1 mmHg) (P laser compared to baseline (0.23 vs 0.26). There was also no statistically significant difference in mean VA at other follow-up visits compared to baseline. Peripheral iridotomy closure was encountered in two (6.1%) eyes, one at 1 month and another at 6 months follow-up. There were no complications including hyphema, peripheral anterior synechia formation nor prolonged inflammation throughout the follow-up period. There was no significant loss in corneal endothelial cell counts at 6 months (2255+/-490) compared to baseline (2303+/-386) (P = 0.347).

    Full Text Available Purpose: To study the demographic and clinical profile of the types of primary angle closure patients presenting at a tertiary care center in North India. Materials and Methods: Clinic records of patients diagnosed as primary angle closure were reviewed. International Society of Geographical and Epidemiological Ophthalmology (ISGEO classification scheme was used to categorize patients. Demographic and clinical data including prior management was collected and analyzed. Main Outcome measures were age, sex, symptomatology, best corrected visual acuity (BCVA, intraocular pressure (IOP, gonioscopy, optic disc assessment and visual field defects. Logistic regression model and receiver operating curve (ROC were calculated for predictors of type of glaucoma. Results: Eight hundred and fourteen patients (1603 eyes; males: 380, females: 434 were diagnosed to have various subtypes of angle closure. Mean (±SD age at presentation was significantly higher for males (57.57 ± 11.62 years as compared to females (53.64 ± 10.67 years ( P < 0001. Primary angle closure glaucoma (PACG was most frequently diagnosed subtype (49.38% followed by Primary angle closure (PAC (39.68% and Primary angle closure suspect (PACS (10.93% respectively. The three subtypes differed significantly among their mean IOP (on ANOVA, F = 14.04; P < 0001 using Greenhouse-Geisser correction. Univariate analysis was done to find significant predictors for the outcome of PACG. Logistic regression model and ROC containing the significant predictors yielded a very high AUC of 0.93 with strong discriminatory ability for PACG. Conclusion: In our hospital-based study, the significant predictors for the outcome of PACG included male gender, diminution of vision, the presence of pain and worsening grades of BCVA. Nearly half of PACG presented with advanced disease. In spite of one-third of the patients being diagnosed as angle closure prior to referral, only 8.34% had iridotomy (laser or surgical

    To investigate the incidence of gonioscopic angle closure after 4 years in subjects with gonioscopically open angles but varying degrees of angle closure detected on anterior segment optical coherence tomography (AS OCT; Visante; Carl Zeiss Meditec, Dublin, CA) at baseline. Prospective, observational study. Three hundred forty-two subjects, mostly Chinese, 50 years of age or older, were recruited, of whom 65 were controls with open angles on gonioscopy and AS OCT at baseline, and 277 were cases with baseline open angles on gonioscopy but closed angles (1-4 quadrants) on AS OCT scans. All subjects underwent gonioscopy and AS OCT at baseline (horizontal and vertical single scans) and after 4 years. The examiner performing gonioscopy was masked to the baseline and AS OCT data. Angle closure in a quadrant was defined as nonvisibility of the posterior trabecular meshwork by gonioscopy and visible iridotrabecular contact beyond the scleral spur in AS OCT scans. Gonioscopic angle closure in 2 or 3 quadrants after 4 years. There were no statistically significant differences in age, ethnicity, or gender between cases and controls. None of the control subjects demonstrated gonioscopic angle closure after 4 years. Forty-eight of the 277 subjects (17.3%; 95% confidence interval [CI], 12.8-23; P < 0.0001) with at least 1 quadrant of angle closure on AS OCT at baseline demonstrated gonioscopic angle closure in 2 or more quadrants, whereas 28 subjects (10.1%; 95% CI, 6.7-14.6; P < 0.004) demonstrated gonioscopic angle closure in 3 or more quadrants after 4 years. Individuals with more quadrants of angle closure on baseline AS OCT scans had a greater likelihood of gonioscopic angle closure developing after 4 years (P < 0.0001, chi-square test for trend for both definitions of angle closure). Anterior segment OCT imaging at baseline predicts incident gonioscopic angle closure after 4 years among subjects who have gonioscopically open angles and iridotrabecular contact on AS OCT at

    We report the case of a 75-year-old woman who developed an acute bilateral angle-closure associated with choroidal effusion a day after an uneventful cataract surgery. The same patient had undergone a similarly uneventful cataract surgery two weeks before, under the same protocol, with no postoperative complication in the other eye. Medical treatment, including the use of oral sulfamide-related drugs (acetazolamide), topical beta-blockers and steroids led to a gradual decrease in intraocular pressure (IOP) and choroidal effusion. Despite initial reports suggesting a link between sulfamide-exposure and these rare forms of angle-closure, our report would suggest a more complex pathophysiology behind this intriguing phenomenon.

    To evaluate a novel software capable of automatically grading angle closure on EyeCam angle images in comparison with manual grading of images, with gonioscopy as the reference standard. In this hospital-based, prospective study, subjects underwent gonioscopy by a single observer, and EyeCam imaging by a different operator. The anterior chamber angle in a quadrant was classified as closed if the posterior trabecular meshwork could not be seen. An eye was classified as having angle closure if there were two or more quadrants of closure. Automated grading of the angle images was performed using customized software. Agreement between the methods was ascertained by κ statistic and comparison of area under receiver operating characteristic curves (AUC). One hundred forty subjects (140 eyes) were included, most of whom were Chinese (102/140, 72.9%) and women (72/140, 51.5%). Angle closure was detected in 61 eyes (43.6%) with gonioscopy in comparison with 59 eyes (42.1%, P = 0.73) using manual grading, and 67 eyes (47.9%, P = 0.24) with automated grading of EyeCam images. The agreement for angle closure diagnosis between gonioscopy and both manual (κ = 0.88; 95% confidence interval [CI), 0.81-0.96) and automated grading of EyeCam images was good (κ = 0.74; 95% CI, 0.63-0.85). The AUC for detecting eyes with gonioscopic angle closure was comparable for manual and automated grading (AUC 0.974 vs. 0.954, P = 0.31) of EyeCam images. Customized software for automated grading of EyeCam angle images was found to have good agreement with gonioscopy. Human observation of the EyeCam images may still be needed to avoid gross misclassification, especially in eyes with extensive angle closure.

    Aims Primary angle-closure glaucoma is expected to account for nearly 50% of bilateral glaucoma blindness by 2020. This study was conducted to assess the performance of the scanning peripheral anterior chamber depth analyzer (SPAC) and limbal anterior chamber depth (LACD) as screening methods for angle closure. Methods This study assessed two clinical populations to compare SPAC, LACD, and gonioscopy: the Zhongshan Angle-closure Prevention Trial, from which 370 patients were eligible as closed-angle participants and the Liwan Eye Study, from which 72 patients were selected as open-angle controls. Eligible participants were assessed by SPAC, LACD, and gonioscopy. Results Angle status was defined by gonioscopy. Area under the receiver operating characteristic curve (AUROC) for SPAC was 0.92 (0.89–0.95) whereas AUROC for LACD was 0.94 (0.92–0.97). Using conventional cutoff points, sensitivity/specificity was 93.0%/70.8% for SPAC and 94.1%/87.5% for LACD. Sequential testing using both SPAC and LACD increased the specificity to 94.4% and decreased the sensitivity to 87.0%. Conclusion SPAC has significantly lower specificity than LACD measurement using conventional cutoffs but interpretation of the findings can be performed by modestly trained personnel. PMID:21997356

METHODS: Twenty-nine cases(29 eyesof angle-closure glaucoma with cataract underwent phacoemulsification with foldable intraocular lens implantation, and the data of visual acuity, intraocular pressure, gonioscopy and complications after operation were statistically analyzed.RESULTS:Postoperatively, 28 eyes(96.5%visual acuity were improved. Intraocular pressure of 25 eyes(86.2%were maintained at a normal level without any IOP lowering drug, intraocular pressure of 3 eyes(10.3%were controlled by IOP lowering eye drops, intraocular pressure of 1 eye(3.5%returned to normal by trabeculectomy. The chamber depth of 29 eyes was increased. 8 eyes were suffered from mild corneal edema, and returned to normal after treatment. CONCLUSION: Characterized by decreasing intraocular pressure, opening anterior chamber, and raising visual acuity, phacoemulsification with foldable intraocular lens implantation is a good operative therapy for primary angle-closure glaucoma complicated with cataract with preoperative goniosynechia closed ≤270°.

    Full Text Available Escitalopram is an antidepressant of the selective serotonin reuptake inhibitor(SSRI class. In this manuscript, we report the case of a female patient who developed bilateral acute angle-closure glaucoma induced by escitalopram. A 46-year-old female patient was admitted to our ophthalmology clinic with complaints of severe pain around the both eyes, headache, nausea, and vomiting for two days. In her past medical history, she was using escitalopram for depression for two years. Visual acuity was at hand movement level in both eyes. Anterior segment examination showed bilateral diffuse conjunctival hyperemia, corneal edema, shallow anterior chamber, and fixed dilated pupils. Intraocular pressure was 47 mmHg in the right and 68 mmHg in the left eye. The diagnosis was acute angle-closure glaucoma, and the escitalopram medication was discontinued. She was treated with topical and systemic antiglaucomatous medication. After the cornea become clear, bilateral peripheral laser iridotomy was done. In the following year, she did not begin escitalopram medication again and no other acute angle-closure attack was seen. (Turk J Ophthalmol 2014; 44:396-9

    To evaluate EyeCam in detecting changes in angle configuration after laser peripheral iridotomy (LPI) in comparison to gonioscopy, the reference standard. Prospective comparative study. Twenty-four subjects (24 eyes) with primary angle-closure glaucoma (PACG) were recruited. Gonioscopy and EyeCam (Clarity Medical Systems) imaging of all 4 angle quadrants were performed, before and 2 weeks after LPI. Images were graded according to angle structures visible by an observer masked to clinical data or the status of LPI, and were performed in a random order. Angle closure in a quadrant was defined as the inability to visualize the posterior trabecular meshwork. We determined the number of quadrants with closed angles and the mean number of clock hours of angle closure before and after LPI in comparison to gonioscopy. Using EyeCam, all 24 eyes showed at least 1 quadrant of angle widening after LPI. The mean number of clock hours of angle closure decreased significantly, from 8.15 +/- 3.47 clock hours before LPI to 1.75 +/- 2.27 clock hours after LPI (P gonioscopy showed 1.0 +/- 1.41 (95% CI, 0.43-1.57) quadrants opening from closed to open after LPI compared to 2.0 +/- 1.28 (95% CI, 1.49-2.51, P = .009) quadrants with EyeCam. Intra-observer reproducibility of grading the extent of angle closure in clock hours in EyeCam images was moderate to good (intraclass correlation coefficient 0.831). EyeCam may be used to document changes in angle configuration after LPI in eyes with PACG. Copyright 2010 Elsevier Inc. All rights reserved.

    To investigate the quantitative changes of circumferential angle closure after laser iridotomy (LI) using the iridotrabecular contact (ITC) index by Swept-Source optical coherence tomography (OCT). In this prospective observational study conducted in a hospital setting, 42 eyes of 36 patients (five males, 31 females) who underwent LI were included. The mean age was 65.00 ± 8.13 years old and the diagnosis included primary angle closure (PAC, 21 eyes), PAC suspect (16 eyes) and PAC glaucoma (five eyes). Optical coherence tomography (OCT) images were obtained pre-LI and at 1 week post-LI. In each image frame, the scleral spur (SS) and the ITC end-point were marked, from which the ITC index was calculated as a percentage of the angle closure across 360°. Measurements inspected before and after LI included: central anterior chamber depth (ACD), anterior chamber volume (ACV), lens vault (LV), nasal and temporal angle opening distance (AOD), angle recess area (ARA), trabecular-iris space area (TISA), trabecular-iris angle (TIA) at 500 μm and 750 μm from the SS and intraocular pressure (IOP). The ITC index and IOP decreased significantly after LI from 71.52 ± 26.29 to 35.31 ± 27.19 and from 20.64 ± 12.72 mmHg to 14.02 ± 3.49 mmHg, respectively (p  0.05), but ACV increased significantly after LI (p angle parameters except for nasal TIAs increased significantly after LI (all p angle showed a significant decrease after LI, but part of the angle closure was not relieved after LI. Other mechanisms besides pupillary block may play a role together in causing angle closure. © 2016 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    A patient with Weill-Marchesani syndrome and angle-closure glaucoma had persistent appositional closure after laser iridotomy that was unrelieved by topical application of either miotic or cycloplegic agents. Argon laser peripheral iridoplasty successfully opened the angle. The patient's sister also had Weill-Marchesani syndrome and angle closure unrelieved by laser iridotomy. Angle closure in Weill-Marchesani syndrome and the response to laser iridotomy and treatment with either miotic or cycloplegic agents may be complex and depends on the relative proportion of pupillary block as a mechanism underlying the angle closure, the functional status of the zonular apparatus, and the degree of angle crowding by the peripheral iris in the presence or absence of peripheral anterior synechiae.

    To compare two spectral domain optical coherence tomography (SD-OCT) devices for the identification of angle structures and the presence of angle closure. This was a prospective comparative study. Consecutive patients underwent gonioscopy and anterior segment imaging using two SD-OCT devices (iVue and Cirrus). Images were evaluated for the ability to detect angle structures such as Schwalbe's line (SL), trabecular meshwork (TM), Schlemm's canal (SC), and scleral spur (SS), and the presence of angle closure. Angle closure was defined as iris contact with the angle wall anterior to the SS on SD-OCT, and nonvisibility of the posterior TM on gonioscopy. Angle closure in an eye was defined as ≥two quadrants of closed angles. AC1 statistic was used to assess the agreement between devices. Of the 69 subjects studied (46.4% male, 84.1% Chinese, mean age 64.0 ± 10.5 years), 40 subjects (40 eyes, 58.0%) had angle closure on gonioscopy. The most identifiable structure on Cirrus SD-OCT was the SS (82.2%) and SL on iVue SD-OCT (74.5%). Angle closure was indeterminable in 14.5% and 50.7% of Cirrus and iVue scans (P gonioscopy was only fair (AC1 = 0.35 and 0.50 for Cirrus and iVue, respectively). It was more difficult to determine angle closure status with iVue compared with Cirrus SD-OCT. There was fair agreement between both devices with gonioscopy for identifying angle closure.

    To systematically evaluate the safety and efficacy of latanoprost monotherapy for the treatment of patients with angle-closure glaucoma. We searched EMBASE, Medline, Cochrane Library, Chinese Journal Full-text Database (CNKI), Chinese Science and Technology Periodical Database (VIP), and Wang Fang using the search terms "latanoprost" (or its commercial name, Xalatan) and "angle-closure glaucoma." Resulting articles were then screened using preset inclusion criteria. Subgroup and sensitivity analyses were performed to evaluate the impact of research population, research type (blinded or controlled), and withdrawal/loss to follow-up. A total of 17 studies (n=807) were included in this meta-analysis. The primary outcome measure was intraocular pressure (IOP). Changes in the mean, peak, and trough IOP from baseline were used as effect measures. As I statistic revealed statistical heterogeneity, the random-effects model was applied. With the exception of 2 non-Asian populations from Australia and Peru, all 13 countries included in this study were from Asia. Latanoprost reduced mean IOP by 7.9 mm Hg (32.4%), peak IOP by 7.4 mm Hg (29.8%), and trough IOP by 7.9 mm Hg (32.5%). The most frequent ocular adverse effects were ocular hyperemia, discomfort (including eye irritation, ocular discomfort, foreign body sensation, and itching), and blurred vision with a total incidence rate of 9.4%, 8.7%, and 5.2%, respectively. Systemic adverse effects encompass rhinitis, dizziness, headache, and nonspecific skin pigmentation. Latanoprost is effective at reducing the IOP of patients with angle-closure glaucoma. Adverse reactions associated with latanoprost were mainly ocular in nature.

    To compare the diagnostic performance of EyeCam (Clarity Medical Systems, Pleasanton, CA, USA) and anterior segment optical coherence tomography (ASOCT, Visante; Carl Zeiss Meditec, Dublin, CA, USA) in detecting angle closure, using gonioscopy as the reference standard. Ninety-eight phakic patients, recruited from a glaucoma clinic, underwent gonioscopy by a single examiner, and EyeCam and ASOCT imaging by another examiner. Another observer, masked to gonioscopy findings, graded EyeCam and ASOCT images. For both gonioscopy and EyeCam, a closed angle in a particular quadrant was defined if the posterior trabecular meshwork was not visible. For ASOCT, angle closure was defined by any contact between the iris and angle anterior to the scleral spur. An eye was diagnosed as having angle closure if ≥2 quadrants were closed. Agreement and area under the receiver operating characteristic curves (AUC) were evaluated. The majority of subjects were Chinese (69/98, 70.4%) with a mean age of 60.6 years. Angle closure was diagnosed in 39/98 (39.8%) eyes with gonioscopy, 40/98 (40.8%) with EyeCam and 56/97 (57.7%) with ASOCT. The agreement (kappa statistic) for angle closure diagnosis for gonioscopy versus EyeCam was 0.89; gonioscopy versus ASOCT and EyeCam versus ASOCT were both 0.56. The AUC for detecting eyes with gonioscopic angle closure with EyeCam was 0.978 (95% CI: 0.93-1.0) and 0.847 (95% CI: 0.76-0.92, p < 0.01) for ASOCT. The diagnostic performance of EyeCam was better than ASOCT in detecting angle closure when gonioscopic grading was used as the reference standard. The agreement between the two imaging modalities was moderate. © 2012 The Authors. Acta Ophthalmologica © 2012 Acta Ophthalmologica Scandinavica Foundation.

    Full Text Available AIM:To compare the dynamic changes of anterior segment parameters especially iris morphology induced by pharmacologic mydriasis between angle closure suspects and normal controls.METHODS:The study group comprised 19 eyes of 19 angle closure suspects and 19 eyes of 19 age- and sex-matched normal open-angle eyes. Pentacam and optical coherence tomography measurements before and 30min after instillation of compound tropicamide eye drop were performed and compared. Biometric evaluations of iris tomography and anterior chamber angle were estimated by a customized image-processing software.RESULTS:Baseline axial length, iris cross sectional area and volume did not differ significantly between angle closure suspects and normal controls. Angle closure suspects had smaller pupil size, narrower anterior segment dimension and axial length, thinner iris with greater curve in comparison with normal controls. Pharmacologic mydriasis led to significant increments in iris thickness at 750 μm, anterior chamber depth and volume, whereas significant decrements in iris curve, cross sectional area and volume in both groups. Angle opening distance at 500 μm was increased significantly in normal controls (from 0.465±0.115 mm to 0.539±0.167 mm, P=0.009, but not in angle closure suspects (from 0.125±0.100 mm to 0.145±0.131 mm, P=0.326. Iris volume change per millimeter of pupil dilation (△IV/△PD decreased significantly less in angle closure suspects than normal controls (-2.47±1.33 mm2 vs -3.63±1.58 mm2, P=0.019. Linear regression analysis showed that the change of angle opening distance at 500 μm was associated most with the change of central anterior chamber depth (β=0.841, P=0.002 and △IV/△PD (β=0.028, P=0.002, followed by gender (β=0.062, P=0.032.CONCLUSION:Smaller iris volume decrement per millimeter of pupil dilation is related significantly with the less anterior angle opening in angle closure suspects after pharmacologic mydriasis.

    The aim of this study was to identify the proportion of patients referred to a tertiary glaucoma centre with a diagnosis of open-angle glaucoma (OAG) who were found to have angle closure glaucoma. Retrospective chart review. Consecutive new patients referred for glaucoma management to a tertiary centre between July 2010 and December 2011 were reviewed. Patients whose referrals for glaucoma assessment specified angle status as "open" were included. The data collected included glaucoma specialist's angle assessment, diagnosis, and glaucoma severity. The status of those with 180 degrees or more Shaffer angle grading of 0 was classified as "closed." From 1234 glaucoma referrals, 179 cases were specified to have a diagnosis of OAG or when angles were known to be open. Of these, 16 (8.9%) were found on examination by the glaucoma specialist to have angle closure. Pseudoexfoliation was present in 4 of 16 patients (25%) in the missed angle-closure glaucoma (ACG) group and 22 of 108 patients (13.5%) in the remaining OAG group. There was no difference found in demographic or ocular biometric parameters between those with confirmed OAG versus those with missed ACG. Almost 1 in 11 patients referred by ophthalmologists to a tertiary glaucoma centre with a diagnosis of OAG were in fact found to have angle closure. Given the different treatment approaches for ACG versus OAG, this study suggests a need to strengthen angle evaluations. Copyright © 2017 Canadian Ophthalmological Society. Published by Elsevier Inc.

    Full Text Available Background: Blotchy pigments in the anterior chamber (AC angle are considered diagnostic of primary angle closure (PAC. But there are no reports either on the prevalence of blotchy pigments in AC angles or the validity of this sign. Aims: To determine the prevalence of blotchy pigments in AC angles and to evaluate their relationship with glaucomatous optic neuropathy (GON in eyes with occludable angles. Setting and Design: Cross-sectional, comparative study. Materials and Methods: Gonioscopy was performed in 1001 eyes of 526 subjects (245 eyes of 148 consecutive, occludable angle subjects and 756 eyes of 378 non-consecutive, open angle subjects, above 35 years of age. Quadrant-wise location of blotchy pigments was documented. Statistical Analysis: Odds of blotchy pigments in occludable angles against that in open angles were evaluated. Relationship of GON with blotchy pigments in occludable angle eyes was evaluated using a multivariate model. Results: Prevalence of blotchy pigments in occludable angles was 28.6% (95% CI, 22.9-34.3 and in open angles was 4.7% (95% CI, 3.2-6.3. Blotchy pigments were more frequently seen in inferior (16% and superior quadrants (15% of occludable angles, and inferior quadrant of open angles (4%. Odds of superior quadrant blotchy pigments in occludable angles were 33 times that in open angles. GON was seen in 107 occludable angle eyes. Blotchy pigments were not significantly associated with GON (odds ratio = 0.5; P = 0.1. Conclusions: Blotchy pigments were seen in 28.6% of occludable angle eyes and 4.7% of open angles eyes. Presence of blotchy pigments in the superior quadrant is more common in occludable angles. Presence of GON in occludable angle eyes was not associated with blotchy pigments.

    Full Text Available ABSTRACT We report a case of bilateral acute angle-closure glaucoma in a patient with undiagnosed granulomatosis with polyangiitis (Wegener's. A 59-year-old man presented with a severe headache, ocular pain, blurred vision, shortness of breath, and mild fever. Clinical examination revealed conjunctival chemosis, corneal edema, and shallow anterior chambers. Closed angles were observed bilaterally on gonioscopy. The patient was treated with intravenous mannitol, oral acetazolamide, and anti-glaucomatous eye drops. Over the following two days, his vision improved and intraocular pressures decreased. Subsequently, laser iridotomies were performed bilaterally and the patient attended consultations with our departments of respiratory medicine, nephrology, and rheumatology and was subsequently diagnosed with granulomatosis with polyangiitis. Bilateral acute angle-closure glaucoma is a very rare ocular manifestation of granulomatosis with polyangiitis. The association of this clinical entity with Wegener's granulomatosis remains unknown.

    Full Text Available Purpose. We aimed to describe a unique case in which a patient developed unilateral optic neuritis and angle-closure glaucoma as a result of snake envenomation. Case Report. Approximately 18 hours after envenomation, a 67-year-old female patient described visual impairment and severe pain in her left eye (LE. The patient’s best corrected visual acuity was 10/10 in the RE and hand motion in the LE. Cranial magnetic resonance imaging showed signs of neuropathy in the left optic nerve. In the LE, corneal haziness, closure of the iridocorneal angle, and mild mydriasis were observed and pupillary light reflex was absent. Intraocular pressure was 25 mmHg and 57 mmHg in the RE and LE, respectively. The patient was diagnosed with acute angle-closure glaucoma in the LE. Optic neuropathy was treated with intravenous pulse methylprednisolone. Left intraocular pressure was within normal range starting on the fourth day. One month after the incident, there was no sign of optic neuropathy; relative afferent pupillary defect and optic nerve swelling disappeared. Conclusions. Patients with severe headache and visual loss after snake envenomation must be carefully examined for possible optic neuropathy and angle-closure glaucoma. Early diagnosis and treatment of these cases are necessary to prevent permanent damage to optic nerves.

    To assess the agreement between gonioscopy and ultrasound biomicroscopy (UBM) in detecting angle closure in Chinese patients with shallow anterior chamber. An observational comparative study of the two different examination methods was conducted. Patients with normal intraocular pressure and temporal peripheral anterior chamber depth less than a quarter of corneal thickness based on slit lamp examination were included in this study from December 2007 to May 2009 in the outpatient clinic of First Hospital of Tsinghua University. Gonioscopy was performed with a Goldman goniolens in dark room first and followed by full beam light and indentation. If the filtering trabecular meshwork was invisible or any peripheral anterior synechia was found, that quadrant of the angle was considered closed. UBM was first undertaken in a darkened room then repeated with normal room lighting. If iridotrabecular apposition was showed, that quadrant of the angle was considered closed. The status of angle closure of each quadrant with different methods was recorded. 85 eyes of 46 patients were included in this study. The agreement between gonioscopy and UBM was poor (Κgonioscopy and UBM was hardly affected by age or sex, while in dark condition, eyes with deeper anterior chamber (P=0.005) or plateau iris configuration tended to produce different results (P=0.075) in the 2 methods. Gonioscopy and UBM are both indispensable methods for detecting angle closure, neither can completely replace the other.

    2014-09-01

    Full Text Available Introduction: Topiramate, a sulfamate-substituted monosaccharide, has been shown to be effective in the treatment of epilepsy and migraine prophylaxis. However, acute secondary angle closure glaucoma and myopia has been shown to develop, especially during the first two weeks of treatment, in a small subset of patients. Case presentation: In the current case report, a 23 year old female patient developed acute myopia and angle closure glaucoma after one week topiramate treatment (25 mg/day for prophylaxis of migraine without aura. The patient was found to have significant conjunctival hyperemia, shallow anterior chamber, and bulging iris in both eyes. Grade 1 acute angle was detected in both eyes during gonioscopic examination. There was no pupillary block and intraocular pressure was 40 mmHg in both eyes. Refraction values were measured at -7.00 and -8.00 in the right and left eye, respectively. The patient and #8217;s visual acuity was at 0.1 to 0.2. Topiramate treatment was promptly discontinued, topical antiglaucomatous treatment was initiated, and laser peripheral iridotomy was performed on each eye. Intraocular pressure has declined to normal limits, refractive values were zero in both eyes and patient and #8217;s visual acuity has restored at follow-up period at 10 days after treatment. Conclusion: Side effects associated with topiramate treatments are known to disappear without long-term damage when the discontinuation of therapy and effective interventions are started early. Therefore, patients and their physicians should be alert for symptoms associated with acute secondary angle closure glaucoma and myopia; especially in the first weeks of topiramate treatment also with low dosage.

    To evaluate the diagnostic performance of the iris-trabecular contact (ITC) index, a measure of the degree of angle-closure, using swept-source optical coherence tomography (SSOCT, CASIA SS-1000, Tomey Corporation, Nagoya, Japan) in comparison with gonioscopy. Prospective observational study. A total of 108 normal subjects and 32 subjects with angle-closure. The SSOCT 3-dimensional angle scans, which obtain radial scans for the entire circumference of the angle, were performed under dark conditions and analyzed using customized software by a single examiner masked to the subjects' clinical details. The ITC index was calculated as a percentage of the angle that was closed on SSOCT images. First-order agreement coefficient (AC1) statistics and area under the receiver operating characteristic curve (AUC) analyses were performed for angle-closure on the basis of the ITC index in comparison with gonioscopy. Angle-closure on gonioscopy was defined as nonvisibility of posterior trabecular meshwork for at least 2 quadrants. Agreement of the ITC index with gonioscopically defined angle-closure was assessed using the AC1 statistic. Study subjects were predominantly Chinese (95.7%) and female (70.7%), with a mean age of 59.2 (standard deviation, 8.9) years. The median ITC index was 15.24% for gonioscopically open-angle eyes (n = 108) and 48.5% for closed-angle eyes (n = 32) (P = 0.0001). The agreement for angle-closure based on ITC index cutoffs (>35% and ≥50%) and gonioscopic angle-closure was 0.699 and 0.718, respectively. The AUC for angle-closure detection using the ITC index was 0.83 (95% confidence interval, 0.76-0.89), with an ITC index >35% having a sensitivity of 71.9% and specificity of 84.3%. The ITC index is a summary measure of the circumferential extent of angle-closure as imaged with SSOCT. The index had moderate agreement and good diagnostic performance for angle-closure with gonioscopy as the reference standard. Copyright © 2013 American Academy of

    Full Text Available To investigate the association between retinitis pigmentosa (RP and acute angle closure during a 15-year follow-up period.Using the Taiwan Longitudinal Health Insurance Database 2000, we identified 382 RP patients based on the diagnostic code of RP (International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM 362.74 made during 1996-2010, excluding subjects under age of 20 years at diagnosis or subjects undergoing lens extraction before the index date. The control group included 3820 randomly selected non-RP subjects matched with the RP patients in age, gender and the index date of diagnosis. The incidence of acute angle closure during the study period was observed based on an ICD-9-CM code of 365.22. Cochran-Mantel-Haenszel test was used to determine the odds ratio (OR of having acute angle closure in RP patients.The mean age at the diagnosis of RP was 51.1 years (standard deviation [SD] 16.7. Acute angle closure occurred in 5 RP patients (1.3% and in 15 controls (0.4%. The mean age with the acute angle closure was 53.3 years (SD 8.0 in RP patients and 64.6 years (SD 8.4 in controls (P = 0.015. After adjusting for age, gender and comorbid disorders, RP patients had 3.64-fold (95% confidence interval [CI], 1.29-10.25, P<0.001 greater odds of having acute angle closure. After stratification for gender and age, the risk of acute angle closure in RP was higher in patients under age of 60 years (adjusted OR 11.84; 95% CI, 2.84-49.48 and male patients (adjusted OR 19.36; 95% CI, 3.43-109.40 (both P = 0.001.RP patients had increased risk of acute angle closure than controls. Contrary to the fact that angle closure disease is more prevalent in elderly females in general population, acute angle closure attack occurred earlier in life and the risk was higher in males among RP patients.

The agreement for angle closure between AS-OCT and gonioscopy was fair at k=0.31 (95% confidence interval, CI: 0.03-0.59 and k=0.35 (95% CI: 0.07-0.63 for reader 1 and 2 respectively. The agreement for angle closure between SD-OCT and gonioscopy was fair at k=0.21 (95% CI: 0.07-0.49 and slight at k=0.17 (95% CI: 0.08-0.42 for reader 1 and 2 respectively. The inter-reader agreement for angle closure in AS-OCT images was moderate at 0.51 (95% CI: 0.13-0.88. The inter-reader agreement for angle closure in SD-OCT images was slight at 0.18 (95% CI: 0.08-0.45. CONCLUSION: Significant proportion of scleral spurs were not visualised with SD-OCT imaging resulting in weaker inter-reader agreements. Identifying other angle landmarks in SD-OCT images will allow more consistent angle closure assessments. Gonioscopy and OCT imaging do not always agree in angle closure assessments but have their own advantages, and should be used together and not exclusively.

    Full Text Available This paper describes a topiramate induced acute bilateral angle-closure glaucoma. This rare adverse effect is an idiosyncratic reaction characterized by uveal effusion and lens forward displacement, leading to increased intraocular pressure and vision loss. We describe a 55 year-old white woman with migraine, spasmodic torticollis and essential tremor, who developed bilateral acute angle-closure glaucoma, one week after starting topiramate 25 mg/day. She was seen at the Ophthalmology Emergency Department of the Fundação João Penido Burnier (Campinas, SP, Brazil with a 4 hours history of blurry vision, ocular pain and bright flashes vision. Slit lamp examination revealed moderate conjunctival injection and corneal edema, and shallow anterior chambers. Intraocular pressure was 48 mmHg in both eyes. Fundoscopic examination findings were normal. She was treated with timolol, brimonidine, dorzolamide, pilocarpine, prednisone acetate eye drops and acetazolamide. One hour after those measures, as the intraocular pressure was 30 mmHg, she received a manitol intravenous injection and the intraocular pressure normalized. After 24 hours an iridotomy with Yag laser was performed. Topiramate was discontinued and she was totally recovered after one week.

    Angle-closure glaucoma is a major cause of irreversible visual impairment and can be identified by measuring the anterior chamber angle (ACA) of the eye. The ACA can be viewed clearly through anterior segment optical coherence tomography (AS-OCT), but the imaging characteristics and the shapes and locations of major ocular structures can vary significantly among different AS-OCT modalities, thus complicating image analysis. To address this problem, we propose a data-driven approach for automatic AS-OCT structure segmentation, measurement, and screening. Our technique first estimates initial markers in the eye through label transfer from a hand-labeled exemplar data set, whose images are collected over different patients and AS-OCT modalities. These initial markers are then refined by using a graph-based smoothing method that is guided by AS-OCT structural information. These markers facilitate segmentation of major clinical structures, which are used to recover standard clinical parameters. These parameters can be used not only to support clinicians in making anatomical assessments, but also to serve as features for detecting anterior angle closure in automatic glaucoma screening algorithms. Experiments on Visante AS-OCT and Cirrus high-definition-OCT data sets demonstrate the effectiveness of our approach.

    Full Text Available A 27-year-old woman developed bilateral acute angle closure glaucoma (AACG and transient myopia after taking oseltamivir for four days. On the fourth day, she received systemic and topical intraocular pressure (IOP-lowering agents, and IOP decreased in both eyes. However, her visual acuity was unchanged. A myopic shift of -5.25 D OD and -5.0 D OS was estimated to have occurred in the acute phase. A-scan ultrasonography and Pentacam showed markedly shallow anterior chambers and increased lens thickness. Ultrasound biomicroscopy revealed an annular ciliochoroidal effusion with forward displacement of the lens-iris diaphragm. Ciliochoroidal effusion and transient myopia were resolved after discontinuation of oseltamivir.

    Full Text Available AIM:To investigate the trabecular-iris angle with ultrasound biomicroscopy (UBM post cataract extraction after an acute attack of phacomorphic angle closure.METHODS: This prospective study involved 10 cases of phacomorphic angle closure that underwent cataract extraction and intraocular lens insertion after intraocular pressure (IOP lowering. Apart from visual acuity and IOP, the trabecular-iris angle was measured by gonioscopy and UBM at 3 months post attack.RESULTS: In 10 consecutive cases of acute phacomorphic angle closure from December 2009 to December 2010, gonioscopic findings showed peripheral anterior synechiae (PAS ≤ 90° in 30% of phacomorphic patients and a mean Shaffer grading of (3.1±1.0. UBM showed a mean angle of (37.1°±4.5° in the phacomorphic eye with the temporal quadrant being the most opened and (37.1°±8.0° in the contralateral uninvolved eye. The mean time from consultation to cataract extraction was (1.4±0.7 days and the mean total duration of phacomorphic angle closure was (3.6±2.8 days but there was no correlation to the degree of angle closure on UBM (Spearman correlation P=0.7. The presenting mean IOP was (50.5±7.4 mmHg and the mean IOP at 3 months was (10.5±3.4 mmHg but there were no correlations with the degree of angle closure (Spearman correlations P=0.9.CONCLUSION:An open trabecular-iris angle and normal IOP can be achieved after an acute attack of phacomorphic angle closure if cataract extraction is performed within 1 day - 2 days after IOP control. Gonioscopic findings were in agreement with UBM, which provided a more specific and object angle measurement. The superior angle is relatively more narrowed compared to the other quadrants. All contralateral eyes in this series had open angles.

  20. A New Acute Attack of Angle Closure Glaucoma Animal Model with Healon 5

    Full Text Available Acute angle closure glaucoma (AACG is an ocular emergency and sight -threatening disease in which the intraocular ocular pressure (IOP rises suddenly due to blockage of aqueous humor outflow. It can cause permanent loss in visual acuity and visual field. In animal study, the well-established model to study AACG is by fluid infusion and by adjusting the bottle level, a high IOP can be induced in a few seconds. However, there is no blockage of aqueous outflow and the pressure rise is unrealistically fast. To mimic human AACG, we suggest to use Healon 5, an ophthalmic viscosurgical device, which is injected intracamerally to block the aqueous outflow. The IOP is allowed to build up naturally. We found that, with this technique, the IOP elevated at a rate of 0.57 mmHg/min before it hit 40 mmHg, which is considered as AACG in human. The maximum IOP registered was above 70 mmHg. Thinning of retinal nerve fiber layer (RNFL and neural cells lost were seen. Visual function evaluated by ERG showed reduction in a-wave, b-wave, photopic negative response (PhNR and oscillatory potentials (OPs activities. In conclusion, Healon 5 is effective in inducing acute transient rise in IOP which mimics human AACG.

    Full Text Available We report the case of a 29-year-old female patient who presented with an acute onset of anisocoria, blurred vision, nausea and severe left-sided headache. There was no history of trauma, drug abuse, or instillation of topical mydriatic compounds. The ocular history was negative for similar events. On presentation, her visual acuity was 0.2 in the left and 1.0 in the right eye with a +2.5 dpt sph. correction. Slit-lamp examination demonstrated a shallow anterior chamber as well as the presence of iris nodules in both eyes. These nodules were identified as Lisch nodules as the patient referred to the previous diagnosis as being neurofibromatosis type 1. A third nerve palsy was considered, but a brain MRI showed normal results. Her ocular motility was normal, but the left pupil was mydriatic and poorly reacting to light, with an associated raised intraocular pressure (IOP of 38 mm Hg. An examination of the fellow eye was normal, with the IOP measuring 18 mm Hg. Gonioscopy of the right eye showed a narrow angle. On further anamnestic investigation, the patient revealed that the pain and the blurred vision begun in the morning while she was helping her mother in the garden. Finally, after showing the patient a picture of Datura flowers, which she recognized immediately, we made the unusual diagnosis of angle closure glaucoma by Datura, a well-known toxic plant with mydriatic properties. The patient was successfully treated with systemic acetazolamide and topical pilocarpine.

    To evaluate the effectiveness of slitlamp optical coherence tomography (SL-OCT) and Scanning Peripheral Anterior Chamber depth analyzer (SPAC) in detecting angle closure, using gonioscopy as the reference standard. A total of 153 subjects underwent gonioscopy, SL-OCT, and SPAC. The anterior chamber angle (ACA) was classified as closed on gonioscopy if the posterior trabecular meshwork could not be seen; with SL-OCT, closure was determined by contact between the iris and angle wall anterior to the scleral spur; and with SPAC by a numerical grade of 5 or fewer and/or a categorical grade of suspect or potential. A closed ACA was identified in 51 eyes with gonioscopy, 86 eyes with SL-OCT, and 61 eyes with SPAC (gonioscopy vs SL-OCT, P gonioscopy vs SPAC, P = .10; SL-OCT vs SPAC, P gonioscopy, SL-OCT detected a closed ACA in 43, whereas SPAC identified 41 (P = .79). An open angle in all 4 quadrants was observed in 102 eyes with gonioscopy, but SL-OCT and SPAC identified 43 and 20 of these eyes, respectively, as having angle closure. The overall sensitivity and specificity for SL-OCT were 84% and 58% vs 80% and 80% for SPAC. Using gonioscopy as the reference, SL-OCT and SPAC showed good sensitivity for detecting eyes at risk of angle closure.

    Full Text Available Purpose: To assess the prevalence and treatment outcomes of angle-closure mechanisms other than pupillary block in a population of Brazilian patients. Methods: A retrospective chart review was conducted to evaluate patients who had undergone laser peripheral iridotomy (LPI due to occludable angles at a single institution between July 2009 and April 2012. An occludable angle was defined as an eye in which the posterior trabecular meshwork was not visible for ≥180° on dark-room gonioscopy. Key exclusion criteria were any form of secondary glaucoma and the presence of >90° of peripheral anterior synechiae. Collected data were age, race, gender, angle-closure mechanism (based on indentation goniocopy and ultrasound biomicroscopy, intraocular pressure (IOP, number of antiglaucoma medications and subsequent management during follow-up. If both eyes were eligible, the right eye was arbitrarily selected for analysis. Results: A total of 196 eyes of 196 consecutive patients (mean age 58.3 ± 11.6 years who underwent LPI were included. In most of the patients [86% (169 patients; 133 women and 36 men], LPI sucessfully opened the angle. Mean IOP was reduced from 18.3 ± 6.4 mmHg to 15.4 ± 4.5 mmHg after LPI (p<0.01. Among the 27 patients with persistent occludable angles, the most common underlying mechanisms were plateau iris (56% and lens-induced component (34%. Most of these patients (85% were treated with argon laser peripheral iridoplasty (ALPI; approximately 90% showed non-occludable angles following the laser procedure (mean IOP reduction of 18.9%, with no significant differences between patients with plateau iris and lens-induced components (p=0.34; mean follow-up of 11.4 ± 3.6 months. Conclusion: Our findings suggest that, in this population of Brazilian patients, several eyes with angle closure were not completely treated with LPI. In the present large case series involving middle-age patients, plateau iris was the leading cause of

    Full Text Available Background: To report the first described case of combined haemolytic and acute angle closure glaucoma secondary to spontaneous intraocular haemorrhages in a patient on excessive anticoagulation. To the best of our knowledge, this is the first case reported in the literature presenting with raised intraocular pressure due to both mechanisms. Case Description: A 90-year-old woman presented with acute pain and reduction in vision in the left eye. Her intraocular pressure (IOP was 55 mm Hg. There were red tinted blood cells in the anterior chamber giving it a reddish hue. The patient was known to have advanced wet macular degeneration. She was taking oral warfarin for atrial fibrillation. Her international normalised ratio (INR was 7.7. B-scan ultrasound of posterior segment showed vitreous and suprachoroidal haemorrhages. An ultrabiomicroscopic examination confirmed open angles. A diagnosis of haemolytic glaucoma secondary to intraocular haemorrhages was made. The IOP was controlled medically. Warfarin was withdrawn and oral vitamin K therapy was initiated leading to a rapid INR reduction. Three days later, her anterior chamber became progressively shallower causing a secondary acute angle closure which was managed medically. After 2 months, the left IOP was well-controlled without any medications and the eye was not inflamed. Her vision in that eye remained perception of light. Conclusion: Patients with suprachoroidal haemorrhages should be closely monitored as they might subsequently develop acute angle closure despite an initially open angle and well-controlled INR and IOP. Excessive anticoagulation needs to be prevented to minimise the risk of sight-threatening complications.

    To compare the quantitative changes of peripheral angle after laser iridotomy (LI) alone (group A) or combined LI and Iridoplasty (group B) using iridotrabecular contact (ITC) index by swept-source anterior segment optical coherence tomography (AS-OCT). In this prospective comparative observational study, OCT images were obtained before and after the procedure. In each image frame, scleral spur (SS) and the ITC end point (EP) were marked and ITC index was calculated as a percentage of the angle closure from 360°. Age, gender, diagnosis and initial ITC index in Group B were matched with group A. Changes in ITC index, anterior chamber angle parameters, and intraocular pressure (IOP) were inspected. Thirty-three eyes (20 patients) with shallow anterior chamber were included in each group. Initial ITC index and initial IOP were not significantly different between the two groups (both p > 0.05). However, ITC index and IOP after the procedure were significantly lower in group B than those in group A (ITC index: 31.3 ± 23.2 in group A, 19.0 ± 21.3 in group B, p = 0.011, IOP: p = 0.004). All anterior chamber angle parameters in group B and all parameters in group A except nasal trabecular-iris angles (TIA) were significantly increased after the laser procedure (all p angle better than LI alone. Iridoplasty may be able to additionally relieve the peripheral angle closure caused by other mechanisms than pupillary block. © 2017 Acta Ophthalmologica Scandinavica Foundation.

    To evaluate changes of nasal and temporal anterior chamber angle (ACA) in subjects with angle closure glaucoma using Spectralis AS-OCT (SAS-OCT) under dark and light conditions. Based on dark-room gonioscopy, 24 subjects with open angles and 86 with narrow angles participated in this study. The nasal and temporal angle opening distance at 500 μm anterior to the scleral spur (AOD500), nasal and temporal ACA were measured using SAS-OCT in light and dark conditions. In 2 groups, ACA and AOD500 in nasal and temporal quadrants were significantly greater in light compared to dark (all with p=0.000). The AOD500 and ACA were significantly higher in nasal than temporal in measured conditions for 2 groups except the ACA and AOD500 of normal group measured in light. The difference between nasal and temporal in dark (29.07 ± 65.71 μm for AOD500 and 5.7 ± 4.07° for ACA) was greater than light (24.86 ± 79.85 μm for AOD500 and 2.09 ± 7.21° for ACA) condition. But the difference was only significant for ACA (p=0.000). The correlation analysis showed a negative correlation between AOD500 and pupil diameter in temporal and nasal quadrants (both with p=0.000). While temporal AOD500 difference correlated with spherical equivalent, temporal and asal gonioscopy, nasal AOD correlated with IOP, temporal and nasal gonioscopy. Clinically important changes in ACA structure could be detected with SAS-OCT in nasal and temporal quadrants under different illumination intensity. The results could help in improvement of examination condition for better and more accurate assessment of individuals with angle closure glaucoma. Copyright © 2014 British Contact Lens Association.

    Chronic obstructive pulmonary disease (COPD) is a prevalent disease, with cigarette smoking being the main risk factor. Prevention is crucial in the fight against COPD. Whereas primary prevention is targeted on whole populations, patient populations are the focus of primary care; therefore, prevention in this setting is mainly aimed at preventing further deterioration of the disease in patients who present with the first signs of disease (secondary prevention). Prevention of COPD in primary care requires detection of COPD at an early stage. An accurate definition of COPD is crucial in this identification process. The benefits of detecting new patients with COPD should be determined before recommending screening and case-finding programs in primary care. No evidence is available that screening by spirometry results in significant health gains. Effective treatment options in patients with mild disease are lacking. Smoking cessation is the cornerstone of COPD prevention. Because cigarette smoking is not only a major cause of COPD but is also a major cause of many other diseases, a decline in tobacco smoking would result in substantial health benefits.

    Angle closure glaucoma, a recognized major world health issue disproportionately affecting women and Asians, is not often considered in our European populations, normotensive subjects, myopic patients, or subjects with a deep anterior chamber. Early diagnosis is worthwhile, as laser peripheral iridotomy (LPI) is an effective one-step treatment of the causal mechanism. We have performed a retrospective study of patients who underwent an LPI, the indication for which was based on "photodynamic" gonioscopy in a darkened room showing iridotrabecular contact in darkness. Such photodynamic gonioscopy was motivated by the presence of even minute defects in the nerve fiber layer as seen on the GDxVCC or the presence of a Van Herick sign (narrow limbal anterior chamber depth). One hundred and three eyes of 103 patients underwent LPI and a minimum 1-year follow-up (mean follow-up almost 2 years). Mean age was 63.7±11.8 years, and women accounted for 63.1% of cases. The vast majority (78.6%) of patients had neither glaucoma nor ocular hypertension. There were 60.1% hyperopes and 39.9% myopes. Over half (57%) had a deep or a very deep anterior chamber. After LPI, there was immediate deepening of the limbal depth of the anterior chamber in 100% of cases. The aqueous humor that flowed forward was almost always viscous-looking. After 1 year, the IOP was 1.3mm Hg±2.4 lower (Pgonioscopy with the Goldmann three-lens mirror (to avoid unintentional indentation with the small diameter lenses in these normotensive eyes) should be performed in a darkened room. LPI is an effective one-step treatment of the underlying cause, that is particularly beneficial if performed early. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    To describe a technique of surgical peripheral iridectomy via a clear-cornea tunnel incision to prevent or treat pupillary block following phacoemulsification. Description of technique and retrospective description results in 20 eyes of 20 patients with acute angle closure with coexisting visually significant cataract undergoing phacoemulsification considered at risk of postoperative papillary block as well as two pseudo-phakic eyes with acute postoperative pupillary-block. Following phacoemulsification and insertion of an intraocular lens, a needle with a bent tip was inserted behind the iris through the corneal tunnel incision. A blunt iris repositor was introduced through the paracentesis and placed above the iris to exert posterior pressure and create a puncture. The size of the puncture was enlarged using scissors. For postoperative pupillary block the same technique was carried out through the existing incisions created for phacoemulsification. Peripheral iridectomy was successfully created in all 22 eyes. At a mean follow-up of 18.77 ± 9.72 months, none of the iridectomies closed or required enlargement. Two eyes had mild intraoperative bleeding and one eye a small Descemet's detachment that did not require intervention. No clinically significant complications were observed. Visual acuity and IOP improved or was maintained in all patients. The incidence of pupillary block in our hospital was 0.09% overall, 0.6% in diabetics and 3.5% in those with diabetic retinopathy. This technique of peripheral iridectomy via the cornea tunnel incision can be safely used during phacoemulsification in eyes at high risk of pupillary block or in the treatment of acute postoperative pupillary-block after cataract surgery. The technique is likely to be especially useful in brown iris, or if a laser is not available.

    Cataract surgery was performed in a 49-year-old woman 16 months after an acute angle-closure glaucoma attack. Zonular dialysis was observed during surgery, but the intraocular lens (IOL) was implanted in the capsular bag uneventfully. At 4 1/2 months, 1 IOL loop wrapped in the bag herniated into the anterior chamber. The patient had no history of trauma. The IOL loop remained in the anterior chamber for 9 months, until the subluxated IOL spontaneously returned to its original position. Six months later, the IOL again dislocated into the anterior chamber.

    The case is presented of a 43 year-old male patient with chronic follicular conjunctivitis, negative bacterial serology, and refractory to local treatment. The incisional biopsy performed showed to be consistent with reactive lymphoid hyperplasia. A year later, a new incisional biopsy showed follicular lymphoma, with no systemic involvement, and he was treated with local radiotherapy. When a chronic follicular conjunctivitis is refractory to treatment, it is essential to perform an incisional biopsy to establish the histopathological diagnosis that can range from chronic inflammation, reactive lymphoid hyperplasia to lymphoma. Follicular lymphoma is rare among conjunctival lymphomas, and the staging is indispensable for the correct therapeutic approach. Copyright © 2014 Sociedad Española de Oftalmología.

    Full Text Available Glaucoma is fast emerging as a major cause of blindness in India. In order to estimate the prevalence of primary open angle glaucoma (POAG and primary angle closure glaucoma (PACG in an urban South Indian population, we examined 972 individuals aged 30-60 years, chosen using a cluster sampling technique from 12 census blocks of Vellore town. They underwent a complete ocular examination, including applanation tonometry and gonioscopy, at the Medical College Hospital. Characteristic field defects on automated perimetry was a diagnostic requisite for POAG. Prevalence (95% CI of POAG, PACG, and ocular hypertension were 4.1 (0.08-8.1, 43.2 (30.14-56.3, and 30.8 (19.8-41.9 per 1,000, respectively. All the PACG cases detected were of the chronic type. Hitherto unavailable community-based information on primary glaucoma in our study population indicates that PACG is about five times as common as POAG.

    Full Text Available Chronic daily headache (CDH refers to a group of non-paroxysmal daily or near-daily headaches with peculiar characteristics that are highly prevalent in populations of neurological clinics and not uncommon among non-patient populations. Most of the patients with CDH had, as primary diagnosis, episodic migraine, which, with the time, presented a progressive frequency, pattern modification and loss of specific migraine characteristics. Other CDH patients had chronic tension-type headache, new daily persistent headache and hemicrania continua, which evolved thru the time to the daily or near-daily presentation. The objective of this study was to determine the primary headache diagnosis among a population of chronic daily headache patients attending a tertiary center for headache treatment. During a 5-year period 651 consecutive chronic daily headache patients attending a private subspecialty center were studied prospectively. The criteria adopted were those proposed by Silberstein et al (1994, revised 1996. Five hundred seventy four patients (88.1% had episodic migraine as primary headache before turning into daily presentation, 52 (8% had chronic tension-type headache, 14 (2.2% had hemicrania continua and 11 patients (1.7% had new daily persistent headache. CDH is quite frequent in patients from clinic-based studies suggesting a high degree of disability. Emphasis on education of patients suffering from frequent primary headaches with regard to measures that are able to decrease suffering and disability as well as better medical education directed to more efficient ways to handle these patients are necessary to improve outcome of such a prevalent condition.

METHODS: Totally 67 patients(69 eyeswith AACG were performed LPIP when intraocular pressure(IOPwas still over 30mmHg after the medicine therapy for 3-6 hours. Visual acuity and intraocular pressure were under detection before laser treatment and 30 minutes, 60 minutes and 2 hours after laser treatment. We measured the anterior chamber depth, width of angle, iris thickness with ultrasound biomicroscope(UBM. Dynamic gonioscopy was used to evaluate the degree of peripheral anterior synechia(PAS.RESULTS: Angle open distance(AODafter iridoplasty was increased(PPF=151.79, PCONCLUSION: LPIP can deepen peripheral anterior chamber, increase the angle access and lower the IOP immediately. It is an important ongoing adjuvant treatment, which can reduce the patients suffering by lowering the IOP quickly, reduce the damage of visual function caused by long-term high intraocular pressure, avoid side effect of the drugs, and can improve the prognosis.

    Objective To evaluate the effectiveness of an early detection program for chronic obstructive pulmonary disease (COPD) in a primary care setting in Japan. Methods Participants of ≥40 years of age who regularly visited a general practitioner's clinic due to chronic disease were asked to complete a COPD screening questionnaire (COPD Population Screener; COPD-PS) and undergo simplified spirometry using a handheld spirometric device. Patients who showed possible COPD were referred to a respiratory specialist and underwent a detailed examination that included spirometry and chest radiography. Results A total of 111 patients with possible COPD were referred for close examination. Among these patients, 27 patients were newly diagnosed with COPD. The patients with COPD were older, had lower BMI values, and had a longer smoking history in comparison to non-COPD patients. COPD patients also had more comorbid conditions. A diagnosis of COPD was significantly associated with a high COPD-PS score (pearly detection of undiagnosed COPD in primary care.

    To compare the performance of gonioscopy and anterior segment (AS) optical coherence tomography (OCT) in detecting angle closure in the different quadrants of the anterior chamber angle (ACA). Cross-sectional observational study. Five hundred two consecutive subjects more than 50 years of age with no previous ophthalmic problems recruited from a community clinic in Singapore. All subjects underwent gonioscopy and AS OCT imaging in the dark. Using gonioscopy, the ACA was graded using the Scheie system by a single examiner masked to AS OCT findings. The ACA in a particular quadrant was classified as closed if the posterior trabecular meshwork could not be seen on gonioscopy. A closed ACA on AS OCT imaging was defined by the presence of any contact between the iris and angle wall anterior to the scleral spur. After excluding eyes with poor image quality, a total of 423 right eyes were included in the analysis. A closed angle in at least 1 quadrant was observed in 59% of the eyes by AS OCT and in 33% of the eyes by gonioscopy (Pgonioscopy were 48% versus 29% superiorly, 43% versus 22% inferiorly, 18% versus 14% nasally, and 12% versus 20% temporally, respectively. Of the 119 of 1692 quadrants that were closed on gonioscopy but open on AS OCT, a steep iris profile was present in 61 (51%) of 119 quadrants on AS OCT, and of the 276 of 1692 quadrants that were open on gonioscopy but closed on AS OCT, 196 (71%) of 276 quadrants showed short iridoangle contact on AS OCT. The highest rates of closed angles on gonioscopy and AS OCT images were observed in the superior quadrant. Anterior segment OCT tended to detect more closed ACAs than gonioscopy, particularly in the superior and inferior quadrants. Variations in the iris profile and level of iridoangle contact also may explain some of the differences seen between gonioscopy and AS OCT.

    Full Text Available Chronic lymphocytic leukemia is an indolent disorder with an increased infectious risk remaining one of the main causes of death. Development of therapies with higher safety profile is thus a challenging issue. Docosahexaenoic acid (DHA, 22:6 is an omega-3 fatty acid, a natural compound of normal cells, and has been shown to display antitumor potency in cancer. We evaluated the potential in vitro effect of DHA in primary CLL cells. DHA induces high level of in vitro apoptosis compared to oleic acid in a dose-dependent and time-dependent manner. Estimation of IC50 was only of 4.813 μM, which appears lower than those reported in solid cancers. DHA is highly active on CLL cells in vitro. This observation provides a rationale for further studies aiming to understand its mechanisms of action and its potent in vivo activity.

    Chronic Kidney Disease (CKD) is a worldwide public health problem. There are few studies in Latin America, especially in primary care settings. Our objective was to determine the prevalence, stages, and associated factors of CKD in primary care setting. We did a retrospective secondary analysis of a database from the Diabetes and Hypertension Primary Care Center of the Peruvian Social Security System (EsSalud) in Lima, Peru. We defined CKD as the presence of eGFR 30 mg/day in 24 h, according to Kidney Disease: Improving Global Outcomes (KDIGO). Factors associated with CKD were evaluated with Poisson Regression models; these factors included age, gender, type 2 diabetes mellitus (DM2), hypertension (HTN), body mass index (BMI), and uric acid. Associations were described as crude and adjusted prevalence ratios (PR) and their 95% confidence intervals (95% CI). We evaluated 1211 patients (women [59%], mean age 65.8 years [SD: 12.7]). Prevalence of CKD was 18%. Using the estimated glomerular filtration rate (eGFR), the prevalence was 9.3% (95% CI 5.3 - 13.3) in patients without HTN or DM2; 20.2% (95% CI 17.6 - 22.8) in patients with HTN, and 23.9% (95% CI 19.4 - 28.4) in patients with DM2. The most common stages were 1 and 2 with 41.5% and 48%, respectively. Factors associated with CKD in the adjusted analysis were: age in years (PR = 1.03, 95% CI 1.01 - 1.04), DM2 (PR = 3.37, 95% CI 1.09 - 10.39), HTN plus DM2 (PR = 3.90, 95% CI 1.54 - 9.88), and uric acid from 5 to DM2, older age and hyperuricemia have higher prevalence of CKD.

    Full Text Available Topiramato é droga derivada das sulfas e utilizada sistemicamente como anticonvulsivante. Pode produzir efusão uveal e causar glaucoma agudo por fechamento angular pelo deslocamento da íris e do cristalino anteriormente, com miopização transitória. O processo cede com a suspensão da droga, se identificado precocemente. Os autores relatam, pela primeira vez na literatura científica nacional, um caso no qual a efusão uveal ocorreu após a administração de topiramato para tratamento de enxaqueca. Paciente branca de 40 anos foi examinada no setor de emergência do Hospital Banco de Olhos de Porto Alegre apresentando cefaléia intensa, dor ocular e diminuição da visão em ambos os olhos. Referia uso de topiramato desde dez dias antes do início dos sintomas. O exame biomicroscópico mostrava injeção conjuntival, quemose e câmara anterior rasa nos dois olhos. A pressão intra-ocular era de 40 mmHg no olho direito e 38 mmHg no olho esquerdo. Os achados fundoscópicos estavam normais nos dois olhos. A ultra-sonografia ocular mostrou efusão uveal e descolamento de coróide bilateral nos dois olhos. Foi realizado o diagnóstico de efusão uveal relacionada com o uso de topiramato. A medicação foi suspensa com melhora do quadro clínico e da acuidade visual três dias após a apresentação inicial. A efusão uveal induzida por drogas ocorre raramente. O topiramato pode causar edema do corpo ciliar e relaxamento da zônula, com conseqüente deslocamento anterior do diafragma irido-cristaliniano, causando miopização aguda e fechamento angular. Como o mecanismo de fechamento angular não envolve bloqueio pupilar, iridectomias periféricas e o uso de mióticos tópicos não são efetivos nesses casos. Houve regressão completa do quadro após a suspensão da medicação.This paper reports a clinical case of uveal effusion in both eyes causing bilateral acute angle closure glaucoma in a young patient after oral administration of topiramate

    To assess the presence, prevalence and clinical characteristics of primary headaches in pediatric patients with chronic rheumatic diseases such as juvenile idiopathic arthritis (JIA) and familial Mediterranean fever (FMF), and to analyze the common pathophysiological mechanisms. In this noncontrolled, cross-sectional study, a semi-structured 53 item headache questionnaire was administered to subjects with FMF and JIA, and interviewed a total sample size of 601 patients younger than16years of age. The questionnaires were then analyzed according to the International Headache Society's diagnostic criteria. Children with FMF (n=378) and JIA (n=223) were studied. Each group was then divided into two subgroups according to whether the subjects reported headache or not. 29.5% of subjects with FMF reported having migraine, 37.6% probable migraine and 32.9% tension type headache (TTH). In JIA group 28.2% were diagnosed with migraine; 41.2% with probable migraine and 30.6% with TTH. No significant difference was found between all subjects with (n=258) and without (n=343) headache for variables such as living in a crowded family (p=0.95), being the first child in the family (p=0.63), academic achievement of the child (p=0.63), high education level (higher than high school) of the mother (p=0.52) and father (p=0.46). The presence of systemic disease was reported not to be effecting the daily life at the time of evaluation by 90.2% of the children with headache and 91.0% of the children without headache (p=0.94). 81.4% of the children reported their headaches were not aggravating with the exacerbation periods of their systemic disease. Family history of hypertension was reported higher by the subjects with headache (13.5% with headache and 4.0% without headache p=0.001). Diabetes mellitus was also reported higher (5.8% with headache; 0.5% without headache; p=0.006). Family history of headache was reported in 28.2% of the patients with headache whereas it was 17.4% of the

    Chronic disease is by far the leading cause of death worldwide and of increasing concern in low- and middle-income countries, including South Africa, where chronic diseases disproportionately affect the poor living in urban settings. The Provincial Government of the Western Cape (PGWC) has prioritized the management of chronic diseases and has developed a policy and framework (Adult Chronic Disease Management Policy 2009) to guide and improve the prevention and management of chronic diseases at a primary care level. The aim of this study is to assess the alignment of current primary care practices with the PGWC Adult Chronic Disease Management policy. One comprehensive primary care facility in a Cape Town health district was used as a case study. Data was collected via semi-structured interviews (n = 10), focus groups (n = 8) and document review. Participants in this study included clinical staff involved in chronic disease management at the facility and at a provincial level. Data previously collected using the Integrated Audit Tool for Chronic Disease Management (part of the PGWC Adult Chronic Disease Management policy) formed the basis of the guide questions used in focus groups and interviews. The results of this research indicate a significant gap between policy and its implementation to improve and support chronic disease management at this primary care facility. A major factor seems to be poor policy knowledge by clinicians, which contributes to an individual rather than a team approach in the management of chronic disease patients. Poor interaction between facility- and community-based services also emerged. A number of factors were identified that seemed to contribute to poor policy implementation, the majority of which were staff related and ultimately resulted in a decrease in the quality of patient care. Chronic disease policy implementation needs to be improved in order to support chronic disease management at this facility. It is possible that similar

    Chronic pain and its associated syndrome have become increasingly prevalent in primary care. With the increase in narcotic use and subsequent adverse events, primary care physicians often seek safer alternatives to treating this condition. Prescribing narcotics necessitates using methods to screen for high abuse risk and protect against misuse. With the understanding of how chronic pain is related to mental illnesses such as depression and posttraumatic stress disorder, mindfulness techniques and behavioral therapy can be used to help decrease the dependence on dangerous opioid medications and help patients understand, accept, and cope with their chronic pain.

  15. Identification and Management of Chronic Pain in Primary Care: a Review.

    Science.gov (United States)

    Mills, Sarah; Torrance, Nicola; Smith, Blair H

    2016-02-01

    Chronic pain is a common, complex, and challenging condition, where understanding the biological, social, physical and psychological contexts is vital to successful outcomes in primary care. In managing chronic pain the focus is often on promoting rehabilitation and maximizing quality of life rather than achieving cure. Recent screening tools and brief intervention techniques can be effective in helping clinicians identify, stratify and manage both patients already living with chronic pain and those who are at risk of developing chronic pain from acute pain. Frequent assessment and re-assessment are key to ensuring treatment is appropriate and safe, as well as minimizing and addressing side effects. Primary care management should be holistic and evidence-based (where possible) and incorporates both pharmacological and non-pharmacological approaches, including psychology, self-management, physiotherapy, peripheral nervous system stimulation, complementary therapies and comprehensive pain-management programmes. These may either be based wholly in primary care or supported by appropriate specialist referral.

    Data on chronic pancreatitis prevalence are scanty and usually limited to hospital-based studies. Investigating chronic pancreatitis prevalence in primary care. Participating primary care physicians reported the prevalence of chronic pancreatitis among their registered patients, environmental factors and disease characteristics. The data were centrally reviewed and chronic pancreatitis cases defined according to M-ANNHEIM criteria for diagnosis and severity and TIGAR-O classification for etiology. Twenty-three primary care physicians participated in the study. According to their judgment, 51 of 36.401 patients had chronic pancreatitis. After reviewing each patient data, 11 turned out to have definite, 5 probable, 19 borderline and 16 uncertain disease. Prevalence was 30.2/100.000 for definite cases and 44.0/100.000 for definite plus probable cases. Of the 16 patients with definite/probable diagnosis, 8 were male, with mean age of 55.6 (±16.7). Four patients had alcoholic etiology, 5 post-acute/recurrent pancreatitis, 6 were deemed to be idiopathic. Four had pancreatic exocrine insufficiency, 10 were receiving pancreatic enzymes, and six had pain. Most patients had initial stage and non-severe disease. This is the first study investigating the prevalence of chronic pancreatitis in primary care. Results suggest that the prevalence in this context is higher than in hospital-based studies, with specific features, possibly representing an earlier disease stage.

    Malaria parasites often manage to maintain an infection for several months or years in their vertebrate hosts. In humans, rodents and birds, most of the fitness costs associated with malaria infections are in the short initial primary (high parasitaemia) phase of the infection, whereas the chronic phase (low parasitaemia) is more benign to the host. In wild birds, malaria parasites have mainly been studied during the chronic phase of the infection. This is because the initial primary phase of infection is short in duration and infected birds with severe disease symptoms tend to hide in sheltered places and are thus rarely caught and sampled. We therefore wanted to investigate the relationship between the parasitaemia during the primary and chronic phases of the infection using an experimental infection approach. We found a significant positive correlation between parasitaemia in the primary peak and the subsequent chronic phase of infection when we experimentally infected great reed warblers (Acrocephalus arundinaceus) with Plasmodium ashfordi. The reason for this association remains to be understood, but might arise from individual variation in exoerythrocytic parasite reservoirs in hosts, parasite antigenic diversity and/or host genetics. Our results suggest that the chronic phase parasitaemia can be used to qualitatively infer the parasitaemia of the preceding and more severe primary phase, which is a very important finding for studies of avian malaria in wild populations.

    The introduction of eGFR reporting and publication of national CKD guidelines has led to major challenges in primary and secondary care, leading to an increase in the number of referrals to nephrology clinics. We have shown that introduction of a renal patient care pathway reduces nephrology referrals and enables managed discharges of CKD patients to primary care. The aim of this article is to examine the outcome of patients discharged to primary care to find out if there is an associated risk with increased discharge supported by the patient pathway. The study was carried out within a single NHS Trust covering a population of 560,000. All patients discharged from the trust's renal outpatient clinic between June 2007 and July 2008 were identified. Patient notes and the local laboratory database systems were used to determine the source and timing of tests. A total of 31 new referrals and 57 regular follow-ups were discharged during this period. The median age of discharge was 67.5 years. Most subjects (60%) had CKD stage 3 at the time of discharge. A total of 23% of discharges were categorized as CKD stages 1, 2 or normal and 17% of patients had CKD stage 4. Overall, 93% had stable eGFRs prior to discharge, 77.5% of patients had blood pressure within threshold (140/90 according to UK CKD guidelines) and 97.7% of patients had haemoglobins >10 g/dl. Post-discharge 83% of patients had eGFRs recorded by their general practitioner and 92.6% of these were measured within appropriate time frames as per CKD guidelines. The majority of patients (82%) had either improved or stable eGFR post-discharge and only three patients had a significant decline in their eGFR. These data indicate that selected CKD patients can be appropriately discharged from secondary care and adequately monitored in primary care. Furthermore, we have shown that this was a safe practice for patients.

    Chronic pain is a prevalent chronic condition with significant burden and economic impact in the United States. Chronic pain is particularly abundant in primary care, with an estimated 52% of chronic pain patients obtaining care from primary care physicians (PCPs). However, PCPs often lack adequate training and have limited time and resources to effectively manage chronic pain. Chronic pain management is complex in nature because of high co-occurrence of psychiatric disorders and other medical comorbidities in patients. This article describes a quality improvement initiative conducted by the American College of Physicians (ACP), in collaboration with the Kentucky ACP Chapter, and the Center for Health Services and Outcomes Research at the Johns Hopkins Bloomberg School of Public Health, to enhance chronic pain management in 8 primary care practices participating in Accountable Care Organizations in Kentucky, with a goal of enhancing the screening, diagnosis, and treatment of patients with chronic pain.

    Objective was to study the comparison between the primary closure and open technique after excision of chronic sacrococcygeal pilonidal sinus. A randomized study was designed and 77 patients with chronic sacrococcygeal pilonidal sinus were included in this study. This study took place in Rizgary Teaching Hospital, Erbil, Kurdistan, Iraq, from January 1997 to August 2003. The patients were separated into 2 groups; Group A (37 patients) were treated by open method (excision and healing by secondary intention) and Group B (40 patients) for whom primary midline suturing was performed after excision of the pilonidal sinus. The follow up ranged from 1.5-5.5 years (mean 4.16) was through outpatient visits. The Student t test was applied for statistical analysis for the operating time, hospital-stay, time off from work and wound healing time; and the results show extremely significant differences between the 2 groups (p<0.0001). The statistical analysis of the total number of postoperative complications of both techniques showed a significant difference (p=0.0401), while the differences were insignificant for each complication when analyzed separately. Excision and primary closure for chronic sacrococcygeal pilonidal sinus is superior to excision and healing by secondary intention. We believe that primary midline suturing is a useful method for management of chronic sacrococcygeal pilonidal sinus. (author)

  6. Left ventricular remodelling in chronic primary mitral regurgitation: implications for medical therapy.

    Science.gov (United States)

    McCutcheon, Keir; Manga, Pravin

    Surgical repair or replacement of the mitral valve is currently the only recommended therapy for severe primary mitral regurgitation. The chronic elevation of wall stress caused by the resulting volume overload leads to structural remodelling of the muscular, vascular and extracellular matrix components of the myocardium. These changes are initially compensatory but in the long term have detrimental effects, which ultimately result in heart failure. Understanding the changes that occur in the myocardium due to volume overload at the molecular and cellular level may lead to medical interventions, which potentially could delay or prevent the adverse left ventricular remodelling associated with primary mitral regurgitation. The pathophysiological changes involved in left ventricular remodelling in response to chronic primary mitral regurgitation and the evidence for potential medical therapy, in particular beta-adrenergic blockers, are the focus of this review.

    Consistent and standardized coding for chronic conditions is associated with better care; however, coding may currently be limited in electronic medical records (EMRs) used in Canadian primary care.Objectives To implement data management activities in a community-based primary care organisation and to evaluate the effects on coding for chronic conditions. Fifty-nine family physicians in Toronto, Ontario, belonging to a single primary care organisation, participated in the study. The organisation implemented a central analytical data repository containing their EMR data extracted, cleaned, standardized and returned by the Canadian Primary Care Sentinel Surveillance Network (CPCSSN), a large validated primary care EMR-based database. They used reporting software provided by CPCSSN to identify selected chronic conditions and standardized codes were then added back to the EMR. We studied four chronic conditions (diabetes, hypertension, chronic obstructive pulmonary disease and dementia). We compared changes in coding over six months for physicians in the organisation with changes for 315 primary care physicians participating in CPCSSN across Canada. Chronic disease coding within the organisation increased significantly more than in other primary care sites. The adjusted difference in the increase of coding was 7.7% (95% confidence interval 7.1%-8.2%, p Data management activities were associated with an increase in standardized coding for chronic conditions. Exploring requirements to scale and spread this approach in Canadian primary care organisations may be worthwhile.

    Sjögren's syndrome is a frequent auto-immune disorder with a pulmonary location in almost 10% of the patients. Although bronchial involvement is very common, most patients only complain of cough and this involvement rarely results in severe symptoms or chronic respiratory failure are rarely observed. We describe here 5 patients with severe chronic bronchiolitis revealing primary Sjögren's syndrome. The lung involvement resulted in chronic bronchorrhea, recurrent sinusitis, diffuse bronchiolar nodules with bronchiectasis on the CT scan, and a severe obstructive airway pattern on lung function tests. Improvement was obtained in 4 patients with combination of inhaled corticosteroids, inhaled long acting beta-agonists, and a low dose of erythromycin. Copyright © 2010 Elsevier Ltd.

    The Chronic Care Model (CCM) is a framework developed to redesign care delivery for individuals living with chronic diseases in primary care. The CCM and its various components have been widely adopted and evaluated, however, little is known about different primary care experiences with its implementation, and the factors that influence its successful uptake. The purpose of this review is to synthesize findings of studies that implemented the CCM in primary care, in order to identify facilitators and barriers encountered during implementation. This study identified English-language, peer-reviewed research articles, describing the CCM in primary care settings. Searches were performed in three data bases: Web of Knowledge, Pubmed and Scopus. Article abstracts and titles were read based on whether they met the following inclusion criteria: 1) studies published after 2003 that described or evaluated the implementation of the CCM; 2) the care setting was primary care; 3) the target population of the study was adults over the age of 18 with chronic conditions. Studies were categorized by reference, study design and methods, participants and setting, study objective, CCM components used, and description of the intervention. The next stage of data abstraction involved qualitative analysis of cited barriers and facilitators using the Consolidating Framework for Research Implementation. This review identified barriers and facilitators of implementation across various primary care settings in 22 studies. The major emerging themes were those related to the inner setting of the organization, the process of implementation and characteristics of the individual healthcare providers. These included: organizational culture, its structural characteristics, networks and communication, implementation climate and readiness, presence of supportive leadership, and provider attitudes and beliefs. These findings highlight the importance of assessing organizational capacity and needs prior

    To describe the characteristics and attitudes toward complementary and alternative medicine (CAM) use among primary care patients with chronic pain disorders and to determine if CAM use is associated with better pain control. Cross-sectional survey. Four hundred sixty-three patients suffering from chronic, nonmalignant pain receiving primary care at 12 U.S. academic medical centers. Self-reported current CAM usage by patients with chronic pain disorders. The survey had an 81% response rate. Fifty-two percent reported current use of CAM for relief of chronic pain. Of the patients that used CAM, 54% agreed that nontraditional remedies helped their pain and 14% indicated that their individual alternative remedy entirely relieved their pain. Vitamin and mineral supplements were the most frequently used CAM modalities. There was no association between reported use of CAM and pain severity, functional status, or perceived self-efficacy. Patients who reported having at least a high school education (odds ratio [OR] 1.1, 95% confidence interval [CI] 1.02-1.19, P = 0.016) and high levels of satisfaction with their health care (OR 1.47, 95% CI 1.13-1.91, P = 0.004) were significantly more likely to report using CAM. Complementary and alternative therapies were popular among patients with chronic pain disorders surveyed in academic primary care settings. When asked to choose between traditional therapies or CAM, most patients still preferred traditional therapies for pain relief. We found no association between reported CAM usage and pain severity, functional status, or self-efficacy.

    Primary chronic gastroduodenitis (PCG) is one of the most frequent diseases of the gastrointestinal tract. Timely and efficient treatment of patients with PCG promotes ulcer prevention. In this connection, an urgent problem of restorative medicine is to develop medical programs with active introduction of pharmacophysiotherapeutic complexes, in particular, laser therapy and anti-secretory preparation (famotidine) that increase therapeutic efficacy of treatment of this disease. To this end, we give results of treatment of 50 patients with primary chronic gastroduodenitis (26 having undergone laser therapy only, and 24 having had a combination of laser therapy and famotidine), which demonstrated that the complex action method has a more adequate effect on pathogenetic components in this disease than monotherapy.

    Patients with chronic pain, depression, and substance use disorder (SUD) are often treated in primary care settings. An estimated 52% of patients have a diagnosis of chronic pain, 5% to 13% have depression, and 19% have SUD. These estimates are likely low when considering the fact that 50% of primary care patients with depression and 65% with SUD are undiagnosed or do not seek help. These three conditions have overlapping neurophysiological processes, which complicate the treatment outcomes of a primary physical illness. Behavioral interventions have been widely utilized as adjunctive treatments, yet little is known about what types of behavioral interventions were effective to treat these comorbidities. This systematic review aimed to identify behavioral interventions targeting chronic pain, depression, and SUD in primary care settings. The Cumulative Index to Nursing and Allied Health Literature, Medline, PsycInfo, and Google Scholar databases were searched to identify randomized controlled trials, using a behavioral intervention, involving adults with at least two of the three conditions. This search yielded 1,862 relevant records, and six articles met final selection criteria. A total of 696 participants were studied. Behavioral interventions varied in content, format, and duration. Mindfulness Oriented Recovery Enhancement (MORE), Acceptance and Commitment Therapy (ACT), Interpersonal Psychotherapy adapted for pain (IPT-P), and Cognitive Behavioral Therapy (CBT) showed promising improvements across all studies, albeit with small to moderate effects. MORE, ACT, and CBT combined with mindfulness and Motivational Interviewing had the most promising results for treating chronic pain, depression, and SUD in various combinations in primary care settings. The evidence is mounting that behavioral interventions such as mindfulness-based or cognitive-behavioral interventions are effective strategies for managing patients with comorbidities of chronic pain, depression

  16. Quality of Care for Patients with Chronic Respiratory Diseases: Data for Accreditation Plan in Primary Healthcare.

    There are scarce reports in the literature on factors affecting the assessment of the quality of care for patients with chronic respiratory diseases. Such information is relevant in the accreditation process on implementing the healthcare. The study group consisted of 133 adult patients with chronic respiratory diseases and 125 adult patients with chronic non-respiratory diseases. In the present study, the level of satisfaction from healthcare provided by the primary healthcare unit, disease acceptance, quality of life, health behaviors, and met needs were examined, as well as associations between variables with the use of correspondence analysis. The results are that in patients with chronic respiratory diseases an increase in satisfaction depends on the improvement of well-being in the mental sphere. The lack of problems with obtaining a referral to a specialist and a higher level of fulfilled needs also have a positive effect. Additionally, low levels of satisfaction should be expected in those patients with chronic respiratory diseases who wait for an appointment in front of the office for a long time, report problems with obtaining a referral to additional tests, present a low level of health behaviors, and have a low index of benefits.

    The 'inverse care law' suggests that populations with the poorest health outcomes also tend to have poorer access to high-quality care. The new general practitioner (GP) contract in the UK aimed to reduce variations in care between areas by collecting information on processes and outcomes of chronic disease management. This study investigated whether, despite reductions in inequalities, primary care in deprived areas is still at a disadvantage due to the higher prevalence of chronic diseases, using chronic kidney disease (CKD) as an example. Initially, data from a hospital-based cohort of CKD patients were analysed to investigate the clustering of CKD patients across area-level deprivation using a geographical information system that employed kernel density estimation. Data from the Quality and Outcomes Framework were then analysed to explore the burden of CKD and associated non-communicable chronic diseases (NCD) and assess the potential impact on GPs' workload by area-level deprivation. There was a significant clustering of CKD patients referred to the hospital in the most deprived areas. Both the prevalence of CKD and associated conditions and caseload per GP were significantly higher in deprived areas. In the most deprived areas, there is an increased burden of major chronic disease and a higher caseload for clinicians. These reflect significant differences in workload for practices in deprived areas, which needs to be addressed.

    Work-related anxieties are frequent and have a negative effect on the occupational performance of patients and absence due to sickness. Most important is workplace phobia, that is, panic when approaching or even thinking of the workplace. This study is the first to estimate the prevalence of workplace phobia among primary care patients suffering from chronic mental disorders and to describe which illness-related or workplace-specific context factors are associated with workplace phobia. A convenience sample of 288 primary care patients with chronic mental disorders (70% women) seen by 40 primary care clinicians in Germany were assessed using a standardized diagnostic interview about mental disorders and workplace problems. Workplace phobia was assessed by the Workplace Phobia Scale and a structured Diagnostic and Statical Manual of Mental Disorders-based diagnostic interview. In addition, capacity and participation restrictions, illness severity, and sick leave were assessed. Workplace phobia was found in 10% of patients with chronic mental disorders, that is, approximately about 3% of all general practice patients. Patients with workplace phobia had longer durations of sick leave than patients without workplace phobia and were impaired to a higher degree in work-relevant capacities. They also had a higher degree of restrictions in participation in other areas of life. Workplace phobia seems to be a frequent problem in primary care. It may behoove primary care clinicians to consider workplace-related anxiety, including phobia, particularly when patients ask for a work excuse for nonspecific somatic complaints. © Copyright 2014 by the American Board of Family Medicine.

    Early detection and appropriate management of chronic kidney disease (CKD) in primary care are essential to reduce morbidity and mortality. To assess the quality of care (QoC) of CKD in primary healthcare in relation to patient and practice characteristics in order to tailor improvement strategies. Retrospective study using data between 2008 and 2011 from 47 general practices (207 469 patients of whom 162 562 were adults). CKD management of patients under the care of their general practitioner (GP) was qualified using indicators derived from the Dutch interdisciplinary CKD guideline for primary care and nephrology and included (1) monitoring of renal function, albuminuria, blood pressure, and glucose, (2) monitoring of metabolic parameters, and alongside the guideline: (3) recognition of CKD. The outcome indicator was (4) achieving blood pressure targets. Multilevel logistic regression analysis was applied to identify associated patient and practice characteristics. Kidney function or albuminuria data were available for 59 728 adult patients; 9288 patients had CKD, of whom 8794 were under GP care. Monitoring of disease progression was complete in 42% of CKD patients, monitoring of metabolic parameters in 2%, and blood pressure target was reached in 43.1%. GPs documented CKD in 31.4% of CKD patients. High QoC was strongly associated with diabetes, and to a lesser extent with hypertension and male sex. Room for improvement was found in all aspects of CKD management. As QoC was higher in patients who received structured diabetes care, future CKD care may profit from more structured primary care management, e.g. according to the chronic care model. Quality of care for chronic kidney disease patients in primary care can be improved. In comparison with guideline advice, adequate monitoring of disease progression was observed in 42%, of metabolic parameters in 2%, correct recognition of impaired renal function in 31%, and reaching blood pressure targets in 43% of chronic

    2010-01-01

    Patient-centered chronic care management is a new model for the management of rare chronic diseases such as primary immunodeficiency disease (PIDD). This approach emphasizes helping patients become experts on the management of their disease as informed, involved, and interactive partners in healthcare decisions with providers. Because only a few patients are affected by rare illnesses, these patients are forced to become knowledgeable about their disease and therapies and to seek treatment from a healthcare team, which includes physicians and nurse specialists who are equipped to manage the complexity of the disease and its comorbidities. Importantly, therapy for PIDD can be self-administered at home, which has encouraged the transition toward a proactive stance that is at the heart of patient-centered chronic care management. We discuss the evolution of therapy, the issues with the disease, and challenges with its management within the framework of other chronic disease management programs. Suggestions and rationale to move case management of PIDD forward are presented with the intent that sharing our experiences will improve process and better manage outcomes in this patient population. The patient-centered model for the management of PIDD is applicable to the primary care settings, where nurse case managers assist patients through education, support them and their families, and facilitate access to community resources in an approach, which has been described as "guided care." The model also applies specifically to immunology centers where patients receive treatment or instruction on its self-administration at home. Patient-centered management of PIDD, with its emphasis on full involvement of patients in their treatment, has the potential to improve compliance with treatment, and thus patient outcomes, as well as patients' quality of life. The patient-centered model expands the traditional model of chronic disease management, which relies on evidence

    This study examined the practices used by primary care pediatricians to assess and treat chronic abdominal pain (CAP), as an initial step in guiding clinical practice guideline (CPG) development. A survey was mailed to a random sample of office-based pediatrician members (primary care pediatricians [PCPs]) of the American Medical Association. PCPs (n = 470) provided information about the typical presentation of CAP, assessment/treatment approaches used in their own practice, their definition of a functional gastrointestinal disorder (FGID), and their familiarity with the Rome Criteria for diagnosing FGIDs. Substantial variability among PCPs was noted across all these areas. Results suggest that perceptions and practices of pediatric CAP vary widely among PCPs; no single standard of care emerged to guide development of a CPG for this population. Future research should evaluate the efficacy of specific strategies currently in use to identify potential opportunities for improving assessment and treatment of CAP in pediatric primary care. © The Author(s) 2014.

Totally 48 patients (51 eyes) with primary chronic RRD were included in this prospective interventional clinical cases study, which underwent SB alone from June 2008 to December 2014. Age, sex, symptoms duration, detached extension, retinal hole position, size, type, fovea on/off, proliferative vitreoretinopathy (PVR), posterior vitreous detachment (PVD), baseline best corrected visual acuity (BCVA), operative duration, follow up duration, final BCVA were measured. Pearson correlation analysis, Spearman correlation analysis and multivariate linear stepwise regression were used to confirm predictive factors for better final visual acuity. Student's t-test, Wilcoxon two-sample test, Chi-square test and logistic stepwise regression were used to confirm predictive factors for better vision improvement. Baseline BCVA was 0.8313±0.6911 logMAR and final BCVA was 0.4761±0.4956 logMAR. Primary surgical success rate was 92.16% (47/51). Correlation analyses revealed shorter symptoms duration (r=0.3850, P=0.0053), less detached area (r=0.5489, Ppredictive factors were better baseline BCVA [partial R-square (PR(2))=0.5316, Ppredictive factors for better vision improvement were better baseline vision [odds ratio (OR) =50.369, P=0.0041] and longer follow up duration (OR=1.144, P=0.0067). Independent predictive factors for better visual outcome of primary chronic RRD after SB are better baseline BCVA, shorter symptoms duration, shorter operative duration and longer follow up duration, while independent predictive factors for better vision improvement after operation are better baseline vision and longer follow up duration.

    Some healthcare systems are relieving primary care providers (PCPs) of "the burden" of managing chronic pain and opioid prescribing, instead offloading chronic pain management to pain specialists. Last year the Centers for Disease Control and Prevention recommended a biopsychosocial approach to pain management that discourages opioid use and promotes exercise therapy, cognitive behavioral therapy and non-opioid medications as first-line patient-centered, multi-modal treatments best delivered by an interdisciplinary team. In the private sector, interdisciplinary pain management services are challenging to assemble, separate from primary care and not typically reimbursed. In contrast, in a fully integrated health care system like the Veterans Health Administration (VHA), interdisciplinary clinics already exist, and one such clinic, the Integrated Pain Team (IPT) clinic, integrates and co-locates pain-trained PCPs, a psychologist and a pharmacist in primary care. The IPT clinic has demonstrated significant success in opioid risk reduction. Unfortunately, proposed legislation threatens to dismantle aspects of the VA such that these interdisciplinary services may be eliminated. This Perspective explains why it is critical not only to maintain interdisciplinary pain services in VHA, but also to consider disseminating this model to other health care systems in order to implement patient-centered, guideline-concordant care more broadly.

    Full Text Available Background and objective The aim of this study is to investigate the clinical characteristics of patients with primary bronchopulmonary carcinoma complicated with chronic obstructive pulmonary disease (COPD, and to optimize the early diagnoses in the coexistence of COPD and primary bronchopulmonary carcinoma. Methods The clinical data of 118 patients with COPD complicated with primary bronchopulmonary carcinoma were analyzed retrospectively, including age, sex, smoking history, smoking index, clinical symptoms and signs, pathological type, staging, metastasis site and lung function index. 120 patients with simple COPD were selected as control. Results The smoking rate (55.1% and smoking index ≥400 branch /year (90.8% of the patients with COPD complicated with primary bronchopulmonary carcinoma were higher than the simple COPD group (20.8%, 48.0%. The difference between the two groups was statistically significant (P0.05, while the incidence of hemoptysis, weight loss, chest pain, hoarseness, pleural effusion and atelectasis were significantly higher than those in simple COPD group (P0.05, but the diffusing capacity of carbon monoxide (DLCO of COPD patients complicated with primary bronchopulmonary carcinoma was lower than that of simple COPD patients (P<0.05 . In the COPD patients with primary bronchopulmonary carcinoma, squamous cell carcinoma was the most common pathological type (51.7%. Male patients were mainly squamous cell carcinoma (60.7%, while female patients with adenocarcinoma (69.0%. Conclusion COPD combined with primary bronchopulmonary carcinoma occurs in male smokers more. There is higher incidence of squamous cell carcinoma. When they are first diagnosed, most of them are advanced or located late, due to no specific clinical symptoms at the early stages. Periodic chest CT examination for COPD patients can help early diagnoses of primary bronchopulmonary carcinoma.

    Data on chronic respiratory diseases (CRD) are scarce or unavailable in most African countries. We aimed to determine the prevalence of CRD and associated risk factors in Cape Verde, at the primary healthcare level. In the frame of the Global Alliance Against Chronic Respiratory Diseases, a cross-sectional study was carried out in October 2006 in 3256 outpatients (2142 women) (median age of 30 years) seeking care at primary healthcare departments, through a standardized interview questionnaire during two weeks. The prevalence of emphysema, tuberculosis, chronic bronchitis, rhinoconjunctivitis and asthma were 0.7%, 2%, 4.5%, 12.3% and 6.2%, respectively. Current smoking was associated with emphysema (OR: 3.36; 95% CI: 0.97-11.40) and tuberculosis (OR: 2.14; 95% CI: 1.07-4.30), ever exposed to a dusty workplace with chronic bronchitis (OR: 2.20; CI 95%: 1.50-3.21) and rhinoconjunctivitis (OR: 1.56; CI 95%: 1.23-1.98) and cooking or heating using an open fire with asthma (OR: 1.59; CI 95%: 1.16-2.19). The estimates of attributable risks percent indicated that, in the sample, a noticeable part of CRD could be attributed to active smoking, exposure to dust and biomass. Results varied according to gender, particularly regarding current smoking which was more important for men. Tobacco smoking, exposure to dust at work and using an open fire were important risk factors for CRD. Our results suggest that if actions were taken in order to reduce the aforementioned exposures, an important CRD decrease could be achieved. Copyright © 2015 Elsevier Masson SAS.

    Full Text Available Chronic low back pain is a serious global health problem. There is substantial evidence that physicians' attitudes towards and beliefs about chronic low back pain can influence their subsequent management of the condition.(1 to evaluate the attitudes and beliefs towards chronic low back pain among primary care physicians in Asia; (2 to study the cultural differences and other factors that are associated with these attitudes and beliefs.A cross sectional online survey was sent to primary care physicians who are members of the Hong Kong College of Family Physician (HKCFP. The Pain Attitudes and Beliefs Scale for Physiotherapist (PABS-PT was used as the questionnaire to determine the biomedical and biopsychosocial orientation of the participants.The mean Biomedical (BM score was 34.8+/-6.1; the mean biopsychosocial (BPS score was 35.6 (+/- 4.8. Both scores were higher than those of European doctors. Family medicine specialists had a lower biomedical score than General practitioners. Physicians working in the public sector tended to have low BM and low BPS scores; whereas physicians working in private practice tended to have high BM and high BPS scores.The lack of concordance in the pain explanatory models used by private and public sector may have a detrimental effect on patients who are under the care of both parties. The uncertain treatment orientation may have a negative influence on patients' attitudes and beliefs, thus contributing to the tension and, perhaps, even ailing mental state of a person with chronic LBP.

    To analyze primary care staffing in HMOs and to review the literature on primary care organization and performance in managed care organizations, with an emphasis on the delivery of primary care to the elderly and chronically ill. Analysis of primary care staffing: InterStudy HMO census data on primary care (n = 1,956) and specialist (n = 1,777) physician staffing levels from 1991 through 1995. Primary care organization and performance for the chronically ill and elderly were analyzed using a review of published research. For the staffing-level models, the number of primary care and specialist physicians per 100,000 enrollees was regressed on HMO characteristics (HMO type [group, staff, network, mixed], HMO enrollment, federal qualification, profit status, national affiliation) and community characteristics (per capita income, population density, service area size, HMO competition). For the review of organization and performance, literature published was summarized in a tabular format. The analysis of physician staffing shows that group and staff HMOs have fewer primary care and specialist physicians per 100,000 enrollees than do network and mixed HMOs, which have fewer than IPAs. Larger HMOs use fewer physicians per 100,000 enrollees than smaller HMOs. Federally qualified HMOs have fewer primary care and specialist physicians per 100,000 enrollees. For-profit, nationally affiliated, and Blue Cross HMOs have more primary care and specialist physicians than do local HMOs. HMOs in areas with high per capita income have more PCPs per 100,000 and a greater proportion of PCPs in the panel. HMO penetration decreases the use of specialists, but the number of HMOs increases the use of primary care and specialist physicians in highly competitive markets. Under very competitive conditions, HMOs appear to compete by increasing access to both PCPs and specialists, with a greater emphasis on access to specialists. The review of research on HMO performance suggests that access

    Seven chronic disease prevention and management programs were implemented across Quebec with funding support from a provincial-private industry funding initiative. Given the complexity of implementing integrated primary care chronic disease management programs, a knowledge transfer meeting was held to share experiences across programs and synthesize common challenges and success factors for implementation. The knowledge translation meeting was held in February 2014 in Montreal, Canada. Seventy-five participants consisting of 15 clinicians, 14 researchers, 31 knowledge users, and 15 representatives from the funding agencies were broken up into groups of 10 or 11 and conducted a strengths, weaknesses, opportunities, and threats analysis on either the implementation or the evaluation of these chronic disease management programs. Results were reported back to the larger group during a plenary and recorded. Audiotapes were transcribed and summarized using pragmatic thematic analysis. Strengths to leverage for the implementation of the seven programs include: (1) synergy between clinical and research teams; (2) stakeholders working together; (3) motivation of clinicians; and (4) the fact that the programs are evidence-based. Weaknesses to address include: (1) insufficient resources; (2) organizational change within the clinical sites; (3) lack of referrals from primary care physicians; and (4) lack of access to programs. Strengths to leverage for the evaluation of these programs include: (1) engagement of stakeholders and (2) sharing of knowledge between clinical sites. Weaknesses to address include: (1) lack of referrals; (2) difficulties with data collection; and (3) difficulties in identifying indicators and control groups. Opportunities for both themes include: (1) fostering new and existing partnerships and stakeholder relations; (2) seizing funding opportunities; (3) knowledge transfer; (4) supporting the transformation of professional roles; (5) expand the use of

    Primary and community care are key settings for the effective management of long term conditions. We aimed to evaluate the pattern of health outcomes in chronic disease management interventions for adults with physical health problems implemented in primary or community care settings. The methods were based on our previous review published in 2006. We performed database searches for articles published from 2006 to 2014 and conducted a systematic review with narrative synthesis using the Cochrane Effective Practice and Organisation of Care taxonomy to classify interventions and outcomes. The interventions were mapped to Chronic Care Model elements. The pattern of outcomes related to interventions was summarized by frequency of statistically significant improvements in health care provision and patient outcomes. A total of 9589 journal articles were retrieved from database searches and snowballing. After screening and verification, 165 articles that detailed 157 studies were included. There were few studies with Health Care Organization (1.9% of studies) or Community Resources (0.6% of studies) as the primary intervention element. Self-Management Support interventions (45.8% of studies) most frequently resulted in improvements in patient-level outcomes. Delivery System Design interventions (22.6% of studies) showed benefits in both professional and patient-level outcomes for a narrow range of conditions. Decision Support interventions (21.3% of studies) had impact limited to professional-level outcomes, in particular use of medications. The small number of studies of Clinical Information System interventions (8.9%) showed benefits for both professional- and patient-level outcomes. The published literature has expanded substantially since 2006. This review confirms that Self-Management Support is the most frequent Chronic Care Model intervention that is associated with statistically significant improvements, predominately for diabetes and hypertension.

    Full Text Available Abstract Background Complementary and alternative medicine (CAM is an increasingly common therapy used to treat chronic pain syndromes. However; there is limited information on the utilization and efficacy of CAM therapy in primary care patients receiving long-term opioid therapy. Method A survey of CAM therapy was conducted with a systematic sample of 908 primary care patients receiving opioids as a primary treatment method for chronic pain. Subjects completed a questionnaire designed to assess utilization, efficacy and costs of CAM therapies in this population. Results Patients were treated for a variety of pain problems including low back pain (38.4%, headaches (9.9%, and knee pain (6.5%; the average duration of pain was 16 years. The median morphine equivalent opioid dose was 41 mg/day, and the mean dose was 92 mg/day. Forty-four percent of the sample reported CAM therapy use in the past 12 months. Therapies utilized included massage therapy (27.3%, n = 248, chiropractic treatment (17.8%, n = 162, acupuncture (7.6%, n = 69, yoga (6.1%, n = 55, herbs and supplements (6.8%, n = 62, and prolotherapy (5.9%, n = 54. CAM utilization was significantly related to age female gender, pain severity income pain diagnosis of neck and upper back pain, and illicit drug use. Medical insurance covered chiropractic treatment (81.8% and prolotherapy (87.7%, whereas patients primarily paid for other CAM therapies. Over half the sample reported that one or more of the CAM therapies were helpful. Conclusion This study suggests CAM therapy is widely used by patients receiving opioids for chronic pain. Whether opioids can be reduced by introducing such therapies remains to be studied.

    Full Text Available S100ß a neurotrophic factor mainly released by astrocytes, has been implicated in the pathogenesis of bipolar disorder. Thus, lithium may exert its neuroprotective effects to some extent through S100ß. Furthermore, the possible effects of lithium on astrocytes as well as on interactions between neurons and astrocytes as a part of its mechanisms of actions are unknown. This study was undertaken to determine the effect of lithium on S100β in neurons, astrocytes and a mixture of neurons and astrocytes. Rat primary astrocyte, neuronal and mixed neuro-astroglia cultures were prepared from cortices of 18-day's embryos. Cell cultures were exposed to lithium (1mM or vehicle for 1day (acute or 7 days (chronic. RT-PCR and ELISA determined S100β mRNA and intra- and extracellular protein levels. Chronic lithium treatment significantly increased intracellular S100β in neuronal and neuro-astroglia cultures in comparison to control cultures (P<0.05. Acute and chronic lithium treatments exerted no significant effects on intracellular S100β protein levels in astrocytes, and extracellular S100β protein levels in three studied cultures as compared to control cultures. Acute and chronic lithium treatments did not significantly alter S100β mRNA levels in three studied cultures, compared to control cultures. Chronic lithium treatment increased intracellular S100ß protein levels in a cell-type specific manner which may favor its neuroprotective action. The findings of this study suggest that lithium may exert its neuroprotective action, at least partly, by increasing neuronal S100ß level, with no effect on astrocytes or interaction between neurons and astrocytes.

  16. Labelling chronic illness in primary care: a good or a bad thing?

    Bedson, John; McCarney, Rob; Croft, Peter

    2004-12-01

    Traditionally the management of any chronic condition starts with its diagnosis. The labelling of disease can be beneficial in terms of defining appropriate treatment such as in coronary artery disease. However, sometimes it may be detrimental such as when x-rays are used to diagnose lumbar spondylosis leading to patients inappropriately limiting their activity. Chronic knee pain in the elderly is another example where applying labels is problematical. A common diagnosis in this situation is osteoarthritis, but this label can be applied in two ways: as a radiological diagnosis, or as a clinical one. The x-ray diagnosis, however, does not equate with the clinical syndrome, and vice versa. In addition, diagnosing knee pain as osteoarthritis does not necessarily help in management, since a patient's debility is more dependent upon their clinical signs and symptoms than the presence of radiographic osteoarthritis, and by the same token its clinical counterpart. GPs are consistent in their management of knee pain, but in attempting to diagnose the pain as osteoarthritis, these plans can alter and become more dependent on the actual diagnosis than the clinical picture. As a result management may well diverge from what the current best evidence supports. Diagnosis for diagnosis sake, should therefore be discouraged, and chronic knee pain gives us one example of why this is the case. GPs would be better placed to manage this condition if it was considered more as a regional pain syndrome, perhaps defining it simply as 'chronic knee pain in older people'. This example suggests that there is a pressing need in primary care to carefully consider in chronic disease when it is appropriate to be definitive in diagnosis such that when using disease specific labels, there is definite benefit for the patient and doctor.

    BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common inflammatory disorder associated with lower airway disease. However, only few studies of CRSwNP from outside secondary/tertiary care centres have been published. We recently reported an asthma frequency of 44% and 65...... patients. Compared with controls, a high level of exhaled NO was significantly more prevalent in CRSwNP irrespective of asthma-status. Nasal NO was significantly lower in patients with CRSwNP compared with controls. CONCLUSION: Subclinical eosinophilic lower airway inflammation is common in CRSwNP......% in primary and secondary care patients respectively. Therefore, we hypothesise that inflammation of the lower airways could be present in all CRSwNP patients, even without asthma. Here, we assessed the degree of lower and upper airway inflammation using exhaled and nasal nitric oxide (NO) in primary care...

    The purpose of this time-domain study was to compare pulmonary artery (PA) pulse pressure and wave reflection in chronic pulmonary thromboembolism (CPTE) and primary pulmonary hypertension (PPH). Pulmonary artery pressure waveform analysis provides a simple and accurate estimation of right ventricular afterload in the time-domain. Chronic pulmonary thromboembolism and PPH are both responsible for severe pulmonary hypertension. Chronic pulmonary thromboembolism and PPH predominantly involve proximal and distal arteries, respectively, and may lead to differences in PA pressure waveform. High-fidelity PA pressure was recorded in 14 patients (7 men/7 women, 46 +/- 14 years) with CPTE (n = 7) and PPH (n = 7). We measured thermodilution cardiac output, mean PA pressure (MPAP), PA pulse pressure (PAPP = systolic - diastolic PAP) and normalized PAPP (nPAPP = PPAP/MPAP). Wave reflection was quantified by measuring Ti, that is, the time between pressure upstroke and the systolic inflection point (Pi), deltaP, that is, the systolic PAP minus Pi difference, and the augmentation index (deltaP/PPAP). At baseline, CPTE and PPH had similar cardiac index (2.4 +/- 0.4 vs. 2.5 +/- 0.5 l/min/m2), mean PAP (59 +/- 9 vs. 59 +/- 10 mm Hg), PPAP (57 +/- 13 vs. 53 +/- 13 mm Hg) and nPPAP (0.97 +/- 0.16 vs. 0.89 +/- 0.13). Chronic pulmonary thromboembolism had shorter Ti (90 +/- 17 vs. 126 +/- 16 ms, p PPAP (0.26 +/- 0.01 vs. 0.09 +/- 0.07, p < 0.01). Our study indicated that: 1) CPTE and PPH with severe pulmonary hypertension had similar PA pulse pressure, and 2) wave reflection is elevated in both groups, and CPTE had increased and anticipated wave reflection as compared with PPH, thus suggesting differences in the pulsatile component of right ventricular afterload.

    Full Text Available Abstract Background Kidney disease is the 9th leading cause of death in Singapore. While preventive effects have focused on early detection and education, little is known about the knowledge level of chronic kidney disease (CKD locally. We seek to evaluate the knowledge of CKD among primary care patients. Methods We conducted a cross-sectional survey of a convenience sample of 1520 patients from 3 primary care centers. Those with existing CKD or on dialysis were excluded. Knowledge was assessed based on 7 questions on CKD in the self-administered questionnaire. One point was given for each correct answer with a maximum of 7 points. Results 1435 completed all 7 questions on CKD. Mean age was 48.9 ±15.0 (SD years. 50.9% were male. 62.3% had a secondary and below education and 52.4% had a monthly household income of ≤ $2000. 43.7% had chronic diseases.

    Background Primary care is recognised to have an important role in the delivery of care for people with chronic kidney disease (CKD). However, there is evidence that CKD management is currently suboptimal, with a range of practitioner concerns about its management. Aim To explore processes underpinning the implementation of CKD management in primary care. Design and setting Qualitative study in general practices participating in a chronic kidney disease collaborative undertaken as part of the National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) for Greater Manchester. Method Semi-structured interviews were conducted with GPs and practice nurses (n = 21). Normalisation Process Theory provided a framework for generation and analysis of the data. Results A predominant theme was anxiety about the disclosure of early-stage CKD with patients. The tensions experienced related to identifying and discussing CKD in older people and patients with stage 3A, embedding early-stage CKD within vascular care, and the distribution of work within the practice team. Participants provided accounts of work undertaken to resolve the difficulties encountered, with efforts having tended to focus on reassuring patients. Analysis also highlighted how anxiety surrounding disclosure influenced, and was shaped by, the organisation of care for people with CKD and associated long-term conditions. Conclusion Offering reassurance alone may be of limited benefit, and current management of early-stage CKD in primary care may miss opportunities to address susceptibility to kidney injury, improve self-management of vascular conditions, and improve the management of multimorbidity.

    Menopause occurs at a median age of 51.3 years, and the average US woman who reaches menopause is expected to live another 30 years. The prevalence and incidence of most chronic conditions, such as coronary heart disease, dementia, stroke, fractures, and breast cancer, increase with age; however, the excess risk for these conditions that can be attributed to menopause alone is uncertain. Since the publication of findings from the Women's Health Initiative that hormone therapy use is associated with serious adverse health effects in postmenopausal women, use of menopausal hormone therapy has declined. To update the 2012 US Preventive Services Task Force (USPSTF) recommendation on the use of menopausal hormone therapy for the primary prevention of chronic conditions. The USPSTF reviewed the evidence on the benefits and harms of systemic (ie, oral or transdermal) hormone therapy for the prevention of chronic conditions in postmenopausal women and whether outcomes vary among women in different subgroups or by timing of intervention after menopause. The review did not address hormone therapy for preventing or treating menopausal symptoms. Although the use of hormone therapy to prevent chronic conditions in postmenopausal women is associated with some benefits, there are also well-documented harms. The USPSTF determined that the magnitude of both the benefits and the harms of hormone therapy in postmenopausal women is small to moderate. Therefore, the USPSTF concluded with moderate certainty that combined estrogen and progestin has no net benefit for the primary prevention of chronic conditions for most postmenopausal women with an intact uterus and that estrogen alone has no net benefit for the primary prevention of chronic conditions for most postmenopausal women who have had a hysterectomy. The USPSTF recommends against the use of combined estrogen and progestin for the primary prevention of chronic conditions in postmenopausal women. (D recommendation) The USPSTF

    BACKGROUND: Although multimorbidity has important implications for patient care in general practice, limited research has examined chronic illness and health service utilisation among problem drug users. This study aimed to determine chronic illness prevalence and health service utilisation among problem drug users attending primary care for methadone treatment, to compare these rates with matched \\'controls\\' and to develop and pilot test a valid study instrument. METHODS: A cross-sectional study of patients attending three large urban general practices in Dublin, Ireland for methadone treatment was conducted, and this sample was compared with a control group matched by practice, age, gender and General Medical Services (GMS) status. RESULTS: Data were collected on 114 patients. Fifty-seven patients were on methadone treatment, of whom 52(91%) had at least one chronic illness (other then substance use) and 39(68%) were prescribed at least one regular medication. Frequent utilisation of primary care services and secondary care services in the previous six months was observed among patients on methadone treatment and controls, although the former had significantly higher chronic illness prevalence and primary care contact rates. The study instrument facilitated data collection that was feasible and with minimal inter-observer variation. CONCLUSION: Multimorbidity is common among problem drug users attending general practice for methadone treatment. Primary care may therefore have an important role in primary and secondary prevention of chronic illnesses among this population. This study offers a feasible study instrument for further work on this issue. (238 words).

    Primary care physicians (PCPs) are optimally situated to identify and manage early stage chronic kidney disease (CKD). Nonetheless, studies have documented suboptimal PCP understanding, awareness, and management of early CKD. The TRANSLATE CKD study is an ongoing national, mixed-methods, cluster randomized control trial that examines the implementation of evidence-based guidelines for CKD into primary care practice. As part of the mixed-methods process evaluation, semistructured interviews were conducted by phone with 27 providers participating in the study. Interviews were audio-taped and transcribed. Thematic content analysis was used to identify themes. Themes were categorized according to the 4 domains of Normalization Process Theory (NPT). Identified themes illuminated the complex work undertaken to manage CKD in primary care practices. Barriers to guideline implementation were identified in each of the 4 NPT domains, including (1) lack of knowledge and understanding around CKD (coherence), (2) difficulties engaging providers and patients in CKD management (cognitive participation), (3) limited time and competing demands (collective action), and (4) challenges obtaining and using data to monitor progress (reflexive monitoring). Addressing the barriers to implementation with concrete interventions at the levels at which they occur, informed by NPT, will ultimately improve the quality of CKD patient care. © Copyright 2015 by the American Board of Family Medicine.

    Objective: To describe a practical method for family practitioners to stage chronic obstructive pulmonary disease (COPD) by the use of office spirometry. Methods: This is a review of the lessons learned from evaluations of the use of office spirometry in the primary care setting to identify best practices using the most recent published evaluations of office spirometry and the analysis of preliminary data from a recent spirometry mass screening project. A mass screening study by the American Association for Respiratory Care and the COPD Foundation was used to identify the most effective way for general practitioners to implement office spirometry in order to stage COPD. Results: A simple three-step method is described to identify people with a high pre-test probability in an attempt to detect moderate to severe COPD: COPD questionnaire, measurement of peak expiratory flow, and office spirometry. Clinical practice guidelines exist for office spirometry basics for safety, use of electronic peak flow devices, and portable spirometers. Conclusion: Spirometry can be undertaken in primary care offices with acceptable levels of technical expertise. Using office spirometry, primary care physicians can diagnose the presence and severity of COPD. Spirometry can guide therapies for COPD and predict outcomes when used in general practice.

    Chronic subdural hematoma in the pediatric population often results from trauma. Asymptomatic and benign-appearing subdural collections are generally managed conservatively without operative intervention. Primary intracranial sarcomas are uncommon entities. Diagnosis of sarcoma can be difficult because these lesions often manifest as apparent hematoma. Presented is the case of a primary intracranial mucoid spindle cell sarcoma that arose in a child with a history of benign-appearing bilateral subdural fluid collections in the setting of nonaccidental trauma. The patient was initially managed conservatively because her neurological examination result was normal and her subdural collections decreased in size on repeated imaging. The collections did not resolve completely. Years later, she exhibited weakness, seizure, and an increase in the size of her subdural fluid collection. Subdural drainage was attempted without significant effect. Cytologic assessment of fluid was negative for malignant cells. Magnetic resonance imaging revealed multiple enhancing masses along the subdural collection. The patient eventually underwent craniotomy in which a diagnosis of sarcoma was obtained. Pathological and radiographic findings as well as oncological management are reviewed. The authors also review the natural history and treatment of primary intracranial sarcoma in the pediatric population. Early contrasted magnetic resonance imaging should be obtained in patients with subdural fluid collections that appear asymmetric or do not resolve in the expected time course, despite having a normal neurologic examination result. Negative cytologic assessment does not exclude sarcoma diagnosis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Indigenous Australians experience disproportionately high prevalence of, and morbidity and mortality from chronic illness such as diabetes, renal disease and cardiovascular disease. Improving the understanding of how Indigenous primary care systems are organised to deliver chronic illness care will inform efforts to improve the quality of care for Indigenous people. Methods This cross-sectional study was conducted in 12 Indigenous communities in Australia's Northern Territory. Using the Chronic Care Model as a framework, we carried out a mail-out survey to collect information on material, financial and human resources relating to chronic illness care in participating health centres. Follow up face-to-face interviews with health centre staff were conducted to identify successes and difficulties in the systems in relation to providing chronic illness care to community members. Results Participating health centres had distinct areas of strength and weakness in each component of systems: 1 organisational influence – strengthened by inclusion of chronic illness goals in business plans, appointment of designated chronic disease coordinators and introduction of external clinical audits, but weakened by lack of training in disease prevention and health promotion and limited access to Medicare funding; 2 community linkages – facilitated by working together with community organisations (e.g. local stores and running community-based programs (e.g. "health week", but detracted by a shortage of staff especially of Aboriginal health workers working in the community; 3 self management – promoted through patient education and goal setting with clients, but impeded by limited focus on family and community-based activities due to understaffing; 4 decision support – facilitated by distribution of clinical guidelines and their integration with daily care, but limited by inadequate access to and support from specialists; 5 delivery system

    Effective chronic disease care is dependent on well-organised quality improvement (QI) strategies that monitor processes of care and outcomes for optimal care delivery. Although healthcare is provincially/territorially structured in Canada, there are national networks such as the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) as important facilitators for national QI-based studies to improve chronic disease care. The goal of our study is to improve the understanding of how patients with chronic kidney disease (CKD) are managed in primary care and the variation across practices and provinces and territories to drive improvements in care delivery. The CPCSSN database contains anonymised health information from the electronic medical records for patients of participating primary care practices (PCPs) across Canada (n=1200). The dataset includes information on patient sociodemographics, medications, laboratory results and comorbidities. Leveraging validated algorithms, case definitions and guidelines will help define CKD and the related processes of care, and these enable us to: (1) determine prevalent CKD burden; (2) ascertain the current practice pattern on risk identification and management of CKD and (3) study variation in care indicators (eg, achievement of blood pressure and proteinuria targets) and referral pattern for specialist kidney care. The process of care outcomes will be stratified across patients' demographics as well as provider and regional (provincial/territorial) characteristics. The prevalence of CKD stages 3-5 will be presented as age-sex standardised prevalence estimates stratified by province and as weighted averages for population rates with 95% CIs using census data. For each PCP, age-sex standardised prevalence will be calculated and compared with expected standardised prevalence estimates. The process-based outcomes will be defined using established methods. The CPCSSN is committed to high ethical standards when dealing with

    Full Text Available ABSTRACT Objective: to assess the structure and results obtained by the "Chronic Renal Patients Care Program" in a Brazilian city. Method: epidemiological, cross-sectional study conducted in 14 PHC units and a secondary center from 2010 to 2013. The Donabedian Model was the methodological framework used. A total of 14 physicians, 13 supervisors, and 11 community health agents from primary healthcare were interviewed for the assessment of structure and process and 1,534 medical files from primary healthcare and 282 from secondary care were consulted to assess outcomes. Results: most units lacked sufficient offices for physicians and nurses to provide consultations, had incomplete staffing, and most professionals had not received proper qualification to provide care for chronic renal disease. Physicians from PHC units classified as capable more frequently referred patients to the secondary care service in the early stages of chronic renal disease (stage 3B when compared to physicians of units considered not capable (58% vs. 36% (p=0.049. Capable PHC units also more frequently presented stabilized glomerular filtration rates (51% when compared to partially capable units (36% and not capable units (44% (p=0.046. Conclusion: patients cared for by primary healthcare units that scored higher in structure and process criteria presented better clinical outcomes. Objective: to identify the coping strategies of family members of patients with mental disorders and relate them to family member sociodemographic variables and to the patient's clinical variables. Method: this was a descriptive study conducted at a psychiatric hospital in the interior of the state of São Paulo, with 40 family members of hospitalized patients over the age of 18, and who followed the patient before and during hospitalization. We used tools to characterize the subjects and the Folkman and Lazarus Inventory of Coping Strategies. Results: the coping strategies most often used by

Social-demographic and anthropometric data, cardiovascular risk factors, and diseases established according to electronic clinical records. Serum creatinine was measured using standardised Jaffe kinetic method, and GFR estimated with MDRD-4-IDMS and CKD-EPI. A total of 97,665 subjects (57.3% women, median age 70.0 years [Q1: 65.0, Q3: 77.0]). GFR-MDRD prevalence<60=15.1% (16.6% in women, 13.2% in men; P<.001) and increased with age. Multivariate analysis showed a positive association between GFR-MDRD<60 and age (OR=1.74; 95% CI 1.70 to 1.77), hypertension (OR=2.18; 95% CI 2.08 to 2.30), heart failure (OR=2.03; 95% CI 1.83 to 2.25), atrial fibrillation (OR=1.57; 95% CI 1.41 to 1.76), ischaemic heart disease (OR=1.40; 95% CI 1.30 to 1.50), peripheral arterial disease (OR=1.31; 95% CI 1.09 to 1.57), dyslipidaemia (OR=1.28; 95% CI 1.23 to 1.33), diabetes (OR=1.26; 95% CI 1.17 to 1.34), and stroke (OR=1.17; 95% CI 1.09 to 1.25). The GFR-CKD-EPI model showed an increase in OR with age and male sex, that became significant as a chronic kidney disease risk factor. Chronic kidney disease has considerable prevalence in subjects≥60 years seen in Primary Health Care, more in women, and increasing with age.

    Various organizational-level attributes are being implemented in primary healthcare to improve healthcare delivery. There is a need to describe the distribution and nature of these attributes and explore differences across practices.AimThe aim of this study was to better understand organizational attributes of primary care teams, focusing specifically on team composition, nursing roles, and strategies that support chronic disease management. We employed a cross-sectional survey design. Team composition, nursing roles, availability of health services, and chronic disease management activities were described using the 'Measuring Organizational Attributes of Primary Health Care Survey.'FindingsA total of 76% (n=26 out of 34) of practice locations completed the survey, including family health teams (FHT; n=21) and community health centers (CHC; n=4). Nurse practitioners (NPs) and registered nurses (RNs) were the most common non-physician providers, and CHCs had a greater proportion of non-physician providers than FHTs. There was overlap in roles performed by NPs and RNs, and registered practical nurses engaged in fewer roles compared with NPs and RNs. A greater proportion of FHTs had systematic chronic disease management services for hypertension, depression and Alzheimer's disease compared with CHC practices. The 'Measuring Organizational Attributes of Primary Health Care Survey' was a useful tool to highlight variability in organizational attributes across PHC practices. Nurses are prominent within PHC practices, engaging in a wide range of roles related to chronic disease management, suggesting a need to better understand their contributions to patient care to optimize their roles.

    Blood flow in hematopoietic bone marrow and in nonhematopoietic bone has been measured with a Xe-133 washout method in 20 patients with chronic granulocytic leukemia (CGL) and in seven with primary myelofibrosis. Age-matched healthy persons served as controls. Bone-marrow blood flow in CGL was dependent upon the phase of the disease. In the metamorphosis phase, bone-marrow blood flow was high compared with that in the well-controlled phase. Apart from the initial phase, the mean values for bone blood flow in CGL were increased compared with the values of the healthy controls. In myelofibrosis the bone blood flow was also increased. Bone-marrow blood flow in these diseases was dependent upon the cellularity of bone marrow as measured morphometrically

  17. Is chronic pelvic pain a comfortable diagnosis for primary care practitioners: a qualitative study

    Science.gov (United States)

    2010-01-01

    Background Chronic pelvic pain (CPP) has a prevalence similar to asthma and chronic back pain, but little is known about how general practitioners (GPs) and practice nurses manage women with this problem. A clearer understanding of current management is necessary to develop appropriate strategies, in keeping with current health care policy, for the supported self-management of patients with long term conditions. The aim of this study was to explore GPs' and practice nurses' understanding and perspectives on the management of chronic pelvic pain. Methods Data were collected using semi-structured interviews with a purposive sample of 21 GPs and 20 practice nurses, in three primary care trusts in the North West of England. Data were analysed using the principles of Framework analysis. Results Analysis suggests that women who present with CPP pose a challenge to GPs and practice nurses. CPP is not necessarily recognized as a diagnostic label and making the diagnosis was achieved only by exclusion. This contrasts with the relative acceptability of labels such as irritable bowel syndrome (IBS). GPs expressed elements of therapeutic nihilism about the condition. Despite practice nurses taking on increasing responsibilities for the management of patients with long term conditions, respondents did not feel that CPP was an area that they were comfortable in managing. Conclusions The study demonstrates an educational/training need for both GPs and practice nurses. GPs described a number of skills and clinical competencies which could be harnessed to develop a more targeted management strategy. There is potential to develop facilitated self- management for use in this patient group, given that this approach has been successful in patients with similar conditions such as IBS. PMID:20105323

    Full Text Available A 63-year-old woman presented to the Orthopedic Unit of our hospital complaining of right hip pain of 6 months'duration associated with a worsening limp. Her past medical history included chronic renal insufficiency. Physical examination revealed deep pain in the iliac region and severe restriction of the right hip's articular function in the maximum degrees of range of motion. X-rays and CT scan detected an osteolytic and expansive lesion of the right supra-acetabular region with structural reabsorption of the right iliac wing. 99mTc-MDP whole-body bone scan showed an abnormal uptake in the right iliac region. Bone biopsy revealed an osteolytic lesion with multinucleated giant cells, indicating a brown tumor. Serum intact PTH was elevated (1020 pg/ml; normal values, 12 62 pg/ml, but her serum calcium was normal (total = 9.4 mg/dl, nv 8.5–10.5; ionized = 5.0 mg/dl, nv 4.2–5.4 due to the coexistence of chronic renal failure. 99mTc-MIBI scintigraphy revealed a single focus of sestamibi accumulation in the left retrosternal location, which turned out to be an intrathoracic parathyroid adenoma at surgical exploration. After surgical removal of the parathyroid adenoma, PTH levels decreased to 212 pg/ml. Three months after parathyroidectomy, the imaging studies showed complete recovery of the osteolytic lesion, thus avoiding any orthopedic surgery. This case is noteworthy because (1 primary hyperparathyroidism was not suspected due to the normocalcemia, likely attributable to the coexistence of chronic renal failure; and (2 it was associated with a brown tumor of unusual location (right supra-acetabular region.

    The majority of patients with chronic myeloid leukemia are successfully managed with life-long treatment with tyrosine kinase inhibitors. In patients in chronic phase, other malignancies are among the most common causes of death, raising concerns on the relationship between these deaths and the off-target effects of tyrosine kinase inhibitors. We analyzed the incidence of second primary malignancies, and related mortality, in 514 chronic myeloid leukemia patients enrolled in clinical trials in which imatinib was given as first-line treatment. We then compared the observed incidence and mortality with those expected in the age- and sex-matched Italian general population, calculating standardized incidence and standardized mortality ratios. After a median follow-up of 74 months, 5.8% patients developed second primary malignancies. The median time from chronic myeloid leukemia to diagnosis of the second primary malignancies was 34 months. We did not find a higher incidence of second primary malignancies compared to that in the age- and sex-matched Italian general population, with standardized incidence ratios of 1.06 (95% CI: 0.57-1.54) and 1.61 (95% CI: 0.92-2.31) in males and females, respectively. Overall, 3.1% patients died of second primary malignancies. The death rate in patients with second primary malignancies was 53% (median overall survival: 18 months). Among females, the observed cancer-related mortality was superior to that expected in the age- and sex-matched Italian population, with a standardized mortality ratio of 2.41 (95% CI: 1.26 - 3.56). In conclusion, our analysis of patients with imatinib-treated chronic myeloid leukemia did not reveal a higher incidence of second primary malignancies; however, the outcome of second primary malignancies in such patients was worse than expected.

    Full Text Available ABSTRACT Objective: to assess the health care Primary Health Care professionals provide to diabetes mellitus patients from the perspective of the Modelo de Atenção às Condições Crônicas. Method: qualitative study, using the theoretical framework of Complex Thinking and the Modelo de Atenção às Condições Crônicas and the methodological framework of assessment research. To collect the data, 38 interviews were held with health professionals and managers; observation of the activities by the health teams; and analysis of 25 files of people who received this care. The data analysis was supported by the software ATLAS.ti, using the directed content analysis technique. Results: at the micro level, care was distant from the integrality of the actions needed to assist people with chronic conditions and was centered on the biomedical model. At the meso level, there was disarticulation among the professionals of the Family Health Strategy, between them and the users, family and community. At the macro level, there was a lack of guiding strategies to implement public policies for diabetes in care practice. Conclusion: the implementation of the Modelo de Atenção às Condições Crônicas represents a great challenge, mainly needing professionals and managers who are prepared to work with chronic conditions are who are open to break with the traditional model.

    Our objective was to explore how individual and primary healthcare (PHC) organizational attributes influence patients' ability in chronic illness self-management. We conducted a cohort study, recruiting 776 adults with chronic disease from 33 PHC settings in the province of Quebec. Organizational data on the PHC clinics were obtained from a prior study. Participants were interviewed at baseline, 6 and 12 months, responding to questionnaires on self-efficacy, health status, socio-demographics, healthcare use and experience of care. Multilevel modelling showed that 52.5% of the variance in self-efficacy occurs at the level of the individual and 4.0% at the organizational level. Controlling for diagnosis, patient factors associated with self-efficacy were self-rated health (B coeff 0.76: CI 0.60; 0.92), concurrent depression (B coeff –1.41: CI 1.96; –0.86) and satisfaction with care (B coeff 0.27: CI 0.15; 0.39). None of the organizational attributes was significantly associated with self-efficacy after adjusting for lower-level variables. Patients generally reported receiving little self-management teaching across organizations. PMID:22548102

    Fatigue occurs frequently in patients with cancer, neurological diseases and chronic inflammatory diseases, but the biological mechanisms that lead to and regulate fatigue are largely unknown. When the innate immune system is activated, heat shock proteins (HSPs) are produced to protect cells. Some extracellular HSPs appear to recognize cellular targets in the brain, and we hypothesize that fatigue may be generated by specific HSPs signalling through neuronal or glial cells in the central nervous system. From a cohort of patients with primary Sjögren's syndrome, 20 patients with high and 20 patients with low fatigue were selected. Fatigue was evaluated with a fatigue visual analogue scale. Plasma concentrations of HSP32, HSP60, HSP72 and HSP90α were measured and analysed to determine if there were associations with the level of fatigue. Plasma concentrations of HSP90α were significantly higher in patients with high fatigue compared with those with low fatigue, and there was a tendency to higher concentrations of HSP72 in patients with high fatigue compared with patients with low fatigue. There were no differences in concentrations of HSP32 and HSP60 between the high- and low-fatigue groups. Thus, extracellular HSPs, particularly HSP90α, may signal fatigue in chronic inflammation. This supports the hypothesis that fatigue is generated by cellular defence mechanisms. © The Author(s) 2016.

Teaching Unit of Family of Sestao (Vizcaya) urban environment. 197 CHP patients with subacute, chronic illnesses or in terminal stages or handicapped, that is to say, people who cannot attend the Medical Centre and needing constant home care (longer than 4 weeks) although they do not need to be in hospital at the moment. A questionnaire made up by the researching group. April-June 1992. The clinical histories and home interviews. Mean age (78 +/- 23) years old; 70% were women; average of health problems of patients (4.2 +/- 4); average of drug consumption by patients (3.6 +/- 4); average of one visit to each patient per two months; 75% did not need derivation. The average age of people looking after them was (58 +/- 28) years old and 77.3% of them were women. Their average QL index was (9 +/- 2.4) out of 10, 9.2% had a QL index between 4 and 7 although there was nobody under 3. We have found an old population, mostly women with an average of health problems of (4.24 +/- 4) and who are polymedicated. 9.4 of them are not looked after by anybody. Generally their homes are habitable enough. In 77.3% of the cases the carers are women and 65.6% do not receive any domiciliary help.

    To assess the prevalence of kidney failure in patients from a primary care centre in a basic healthcare district with laboratory availability allowing serum creatinine measurements. An observational descriptive cross-sectional study. A basic healthcare district serving 23,807 people aged ≥ 18 years. Prevalence of kidney failure among 17,240 patients having at least one laboratory measurement available was 8.5% (mean age 77.6 ± 12.05 years). In 33.2% of such patients an occult kidney failure was found (98.8% were women). Prevalence of chronic kidney failure among 10,011 patients having at least 2 laboratory measurements available (≥ 3 months apart) was 5.5% with mean age being 80.1 ± 10.0 years (most severely affected patients were those aged 75 to 84); 59.7% were men and 76.3% of cases were in stage 3. An occult kidney failure was found in 5.3% of patients with women being 86.2% of them (a glomerular filtration rate<60 ml/min was estimated for plasma creatinine levels of 0.9 mg/dl or higher). Comparison of present findings to those previously reported demonstrates the need for further studies on the prevalence of overall (chronic and acute) kidney failure in Spain in order to estimate the real scope of the disease. Primary care physicians play a critical role in disease detection, therapy, control and recording (in medical records). MDRD equation is useful and practical to estimate glomerular filtration rate.

In this study, a voxel-based functional connectivity strength (FCS assessment, a data-driven method based on a theoretical approach, was applied to investigate the effects of insomnia on the intrinsic organization of the whole brain in 27 treatment-naïve CPI patients and 26 well-matched healthy controls (HCs. Compared with HCs, CPI patients exhibited decreased FCS primarily in the right dorsolateral prefrontal cortex, the right medial prefrontal cortex (MPFC, the left basal ganglia/insula, and the right cerebellum anterior lobe (CAL due to decreased functional connectivity patterns. These results suggest that poor sleep quality could impair FCS within the brain, including the MPFC and the CAL, which are important for cognitive control and modulating motor and limbic functions. Additionally, a receiver operator characteristic analysis revealed that altered FCS has moderate sensitivity (76.9%–88.5% and specificity (59.3%–70.4% as a reference indicator to discriminate CPI patients from HCs. Taken together, these findings provide evidence for abnormal intrinsic brain activity in CPI patients and might improve our understanding of the pathophysiological processes that occur in insomnia patients.

N-acetylaspartate (NAA, choline (Cho, myo-inositol (mI, and glutamine/glutamate (Glx were measured with proton magnetic resonance spectroscopy (1H-MRS in left and right SSC. Differences in metabolite concentrations relative to those of controls were evaluated as well as analyses of metabolite correlations within and between SSCs. Relationships between metabolite concentrations and pain characteristics were also evaluated. We found decreased NAA in the left SSC (P = 0.001 and decreased Cho (P = 0.04 along with lower correlations between all metabolites in right SSC (P = 0.007 in LBP compared to controls.

    To describe nursing activities in primary care with patients affected by physical chronic disease and common mental disorders. Patients in primary care who are affected by physical chronic disease and common mental disorders such as anxiety and depression require care and follow-up based on their physical and mental health condition. Primary care nurses are increasingly expected to contribute to the care and follow-up of this growing clientele. However, little is known about the actual activities carried out by primary care nurses in providing this service in the Province of Quebec (Canada). A qualitative descriptive study was conducted. Data were obtained through semistructured individual interviews with 13 nurses practising among patients with physical chronic disease in seven Family Medicine Groups in Quebec (Canada). Participants described five activity domains: assessment of physical and mental health condition, care planning, interprofessional collaboration, therapeutic relationship and health promotion. The full potential of primary care nurses is not always exploited, and some activities could be improved. Evidence for including nurses in collaborative care for patients affected by physical chronic disease and common mental disorders has been shown but is not fully implemented in Family Medicine Groups. Future research should emphasise collaboration among mental health professionals, primary care nurses and family physicians in the care of patients with physical chronic disease and common mental disorders. Primary care nurses would benefit from gaining more knowledge about common mental disorders and from identifying the resources they need to contribute to managing them in an interdisciplinary team. © 2016 John Wiley & Sons Ltd.

    Full Text Available Primary cutaneous malignancies arising in association with chronic lymphocytic leukemia (CLL are notable for their atypical clinical and histological presentation. We report a 69-year-old man with a 17-year history of CLL who presented for evaluation of a well-defined red to violaceous nodule with a central depressed scar on the left lower extremity. Microscopic examination of a punch biopsy revealed an infiltrate of predominantly small lymphocytes with scattered large, atypical epithelioid cells. Immunohistochemical stains revealed diffuse positive staining of the lesional cells with CD20+ and bcl-6+ and focal positive staining with bcl-2+ (negative CD10 and CD23, findings which, in conjunction with the histology, were most compatible with a diagnosis of primary cutaneous follicle center lymphoma (PCFCL. A review of the clinical charts revealed several prior biopsies with varied diagnoses. In light of the most recent biopsy findings, all previous biopsies were re-reviewed and interpreted as PCFCL arising in the setting of CLL. Features contributing to the diagnostic conundrum in this case included an atypical clinical and histological presentation, lack of pertinent clinical history and multiple presentations at different institutions.

    Aim: To assess the efficacy of a primary-care imaging pathway for neurology outpatients, from inception to deployment, compared with traditional outpatient referral. Materials and methods: After local agreement, guidelines were generated providing pathways for diagnosis and treatment of common causes of headache, highlighting 'red-flag' features requiring urgent neurology referral, and selecting patients for direct magnetic resonance imaging (MRI) referral. In addition, reports were clarified and standardized. To evaluate the efficacy of the access pathway, a retrospective sequential review of 100 MRI investigations was performed comparing general practitioner (GP) referral, with traditional neurology referral plus imaging, acquired before the pathway started. Results: No statistically significant difference in rates of major abnormalities, incidental findings or ischaemic lesions were identified between the two cohorts. Reported patient satisfaction was high, with a cost reduction for groups using the pathway. Conclusion: The findings of the present study suggest that a defined access pathway for imaging to investigate chronic headache can be deployed appropriately in a primary-care setting.

    Care management and care managers are becoming increasingly prevalent in primary care medical practice as a means of improving population health and reducing unnecessary care. Care managers are often involved in chronic disease management and associated transitional care. In this study, we examined the communication regarding chronic disease care within 24 primary care practices in Michigan and Colorado. We sought to answer the following questions: Do care managers play a key role in chronic disease management in the practice? Does the prominence of the care manager's connectivity within the practice's communication network vary by the type of care management structure implemented? Individual written surveys were given to all practice members in the participating practices. Survey questions assessed demographics as well as practice culture, quality improvement, care management activities, and communication regarding chronic disease care. Using social network analysis and other statistical methods, we analyzed the communication dynamics related to chronic disease care for each practice. The structure of chronic disease communication varies greatly from practice to practice. Care managers who were embedded in the practice or co-located were more likely to be in the core of the communication network than were off-site care managers. These care managers also had higher in-degree centrality, indicating that they acted as a hub for communication with team members in many other roles. Social network analysis provided a useful means of examining chronic disease communication in practice, and highlighted the central role of care managers in this communication when their role structure supported such communication. Structuring care managers as embedded team members within the practice has important implications for their role in chronic disease communication within primary care.

    Physicians have traditionally been reimbursed for face-to-face visits. A new non-visit-based payment for chronic care management (CCM) of Medicare patients took effect in January 2015. To estimate financial implications of CCM payment for primary care practices. Microsimulation model incorporating national data on primary care use, staffing, expenditures, and reimbursements. National Ambulatory Medical Care Survey and other published sources. Medicare patients. 10 years. Practice-level. Comparison of CCM delivery approaches by staff and physicians. Net revenue per full-time equivalent (FTE) physician; time spent delivering CCM services. If nonphysician staff were to deliver CCM services, net revenue to practices would increase despite opportunity and staffing costs. Practices could expect approximately $332 per enrolled patient per year (95% CI, $234 to $429) if CCM services were delivered by registered nurses (RNs), approximately $372 (CI, $276 to $468) if services were delivered by licensed practical nurses, and approximately $385 (CI, $286 to $485) if services were delivered by medical assistants. For a typical practice, this equates to more than $75 ,00 of net annual revenue per FTE physician and 12 hours of nursing service time per week if 50% of eligible patients enroll. At a minimum, 131 Medicare patients (CI, 115 to 140 patients) must enroll for practices to recoup the salary and overhead costs of hiring a full-time RN to provide CCM services. If physicians were to deliver all CCM services, approximately 25% of practices nationwide could expect net revenue losses due to opportunity costs of face-to-face visit time. The CCM program may alter long-term primary care use, which is difficult to predict. Practices that rely on nonphysician team members to deliver CCM services will probably experience substantial net revenue gains but must enroll a sufficient number of eligible patients to recoup costs.

    Our goals were to determine the prevalence of unusual, debilitating fatigue and the frequency with which it was associated with the chronic fatigue syndrome (CFS) or other physical or psychological illness in an outpatient clinic population. We prospectively evaluated a cohort of 1000 consecutive patients in a primary care clinic in an urban, hospital-based general medicine practice. The study protocol included a detailed history, physical examination, and laboratory and psychiatric testing. Five patients who came because of CFS studies were excluded. Of the remaining 995, 323 reported fatigue, and 271 (27%) complained of at least 6 months of unusual fatigue that interfered with their daily lives. Of the 271, self-report or record review revealed a medical or psychiatric condition that could have explained the fatigue in 186 (69%). Thus, 85 (8.5%) of 995 patients had a debilitating fatigue of at least 6 months' duration, without apparent cause. Of these patients, 48 refused further evaluation, and 11 were unavailable for follow-up; 26 completed the protocol. Three of the 26 were hypothyroid, and one had a major psychiatric disorder. Of the remaining 22 patients, three met Centers for Disease Control and Prevention criteria for CFS, four met British criteria, and 10 met the Australian case definition. The point prevalences of CFS were thus 0.3% (95% confidence interval [CI], 0% to 0.6%), 0.4% (95% CI, 0% to 0.8%), and 1.0% (95% CI, 0.4% to 1.6%) using the Centers for Disease Control and Prevention, British, and Australian case definitions, respectively. These estimates were conservative, because they assumed that none of the patients who refused evaluation or were unavailable for follow-up would meet criteria for CFS. While chronic, debilitating fatigue is common in medical outpatients, CFS is relatively uncommon. Prevalence depends substantially on the case definition used.

    2013-01-01

    Background In response to the increasing demand for better chronic disease management and improved health care efficiency in Ontario, nursing roles have expanded in the primary health care setting. Objectives To determine the effectiveness of specialized nurses who have a clinical role in patient care in optimizing chronic disease management among adults in the primary health care setting. Data Sources and Review Methods A literature search was performed using OVID MEDLINE, OVID MEDLINE In-Process and Other Non-Indexed Citations, OVID EMBASE, EBSCO Cumulative Index to Nursing & Allied Health Literature (CINAHL), the Wiley Cochrane Library, and the Centre for Reviews and Dissemination database. Results were limited to randomized controlled trials and systematic reviews and were divided into 2 models: Model 1 (nurse alone versus physician alone) and Model 2 (nurse and physician versus physician alone). Effectiveness was determined by comparable outcomes between groups in Model 1, or improved outcomes or efficiency in Model 2. Results Six studies were included. In Model 1, there were no significant differences in health resource use, disease-specific measures, quality of life, or patient satisfaction. In Model 2, there was a reduction in hospitalizations and improved management of blood pressure and lipids among patients with coronary artery disease. Among patients with diabetes, there was a reduction in hemoglobin A1c but no difference in other disease-specific measures. There was a trend toward improved process measures, including medication prescribing and clinical assessments. Results related to quality of life were inconsistent, but patient satisfaction with the nurse-physician team was improved. Overall, there were more and longer visits to the nurse, and physician workload did not change. Limitations There was heterogeneity across patient populations, and in the titles, roles, and scope of practice of the specialized nurses. Conclusions Specialized nurses with

    Metastatic pulmonary calcification (MPC) is common in patients with chronic renal failure. The authors experienced a patient with chronic renal failure and primary hyperparathyroidism by parathyroid adenoma accompanied with rapid progressions of MPC and alveolar hemorrhage. Recent chest radiographs, compared with previous chest radiographs, showed rapid accumulation of calcification in both upper lungs. Following up on the high-resolution CT scan after five years demonstrates more increased nodules in size and ground glass opacity. The patient was diagnosed with MPC and alveolar hemorrhage by transbronchial lung biopsy. We assumed rapid progression of MPC and alveolar hemorrhage in underlying chronic renal failures could be a primary hyperparathyroidism which may be caused by parathyroid adenoma detected incidentally. Therefore parathyroid adenoma was treated with ethanol injections. Herein, we have reported on CT findings of MPC with alveolar hemorrhage and reviewed our case along with other articles.

    Full Text Available Introduction: Early detection of Chronic Obstructive Pulmonary Diseases (COPD is the key for its control and management in Primary Health Care. Nurses could significantly contribute to the early detection of COPD if they receive appropriate training and develop skills such as performing spirometry tests and assess early COPD’s signs and symptoms. Aim: To assess the ability of nursing students to detect undiagnosed cases of COPD through a designed spirometry program. Methods: Participants were approached following an open invitation by the local municipal authorities during January-June 2015 in 4 primary health care centres of the island of Crete, Greece. A screening program was conducted using two different diagnostic methods of COPD. All participants completed the ‘International Primary Care Airways Guidelines’ (IPAG questionnaire, a validated instrument for COPD cases identification and performed a spirometry, a gold standard method for the diagnosis of COPD. Nursing students were trained for one month.Two different diagnoses of COPD were given using the interpretations of the spirometry tests and IPAG results for each individual participant (IPAG & GOLD standards. Diagnosis of COPD was based on the spirometry values using the GOLD recommendations (fixed ratio FEV1/FVC<70%. The capacity of nursing students in detecting COPD was based on the degree of agreement (Kappa test and ROC curve between the two diagnoses of COPD (IPAG & GOLD. P-values <0.05 were considered statistically significant. Results: The mean age of the 390 participants was 55.6 (12.7 years old and 46.9% were male. The prevalence of COPD was 20% (78 cases according to IPAG questionnaire and 12.1% (47 cases according to spirometry. However, 31 cases of COPD that were detected using the IPAG, were classified as normal in spirometry, showing middle level of agreement (Kappa=0.71, p<0.001, 47/78 cases. Consequently, a sensitivity and specificity analysis was performed reported

    According to evidence from recent decades, multicomponent programs of psychological intervention in people with chronic pain have reached the highest levels of efficacy. However, there are still many questions left to answer since efficacy has mainly been shown among upper-middle class patients in English-speaking countries and in controlled studies, with expert professionals guiding the intervention and with a limited number of domains of painful experience evaluated. For this study, a program of multicomponent psychological intervention was implemented: (a) based on techniques with empirical evidence, but developed in Spain; (b) at a public primary care center; (c) among patients with limited financial resources and lower education; (d) by a novice psychologist; and (e) evaluating all domains of painful experience using the instruments recommended by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT). The aim of this study was to evaluate this program. We selected a consecutive sample of 40 patients treated for chronic non-cancer pain at a primary care center in Utrera (Seville, Spain), adults who were not in any employment dispute, not suffering from psychopathology, and not receiving psychological treatment. The patients participated in 10 psychological intervention sessions, one per week, in groups of 13-14 people, which addressed psychoeducation for pain; breathing and relaxation; attention management; cognitive restructuring; problem-solving; emotional management; social skills; life values and goal setting; time organization and behavioral activation; physical exercise promotion; postural and sleep hygiene; and relapse prevention. In addition to the initial assessment, measures were taken after the intervention and at a 6-month follow-up. We assessed the program throughout the process: before, during and after the implementation. Results were analyzed statistically (significance and effect size) and from a clinical

    The current diagnostic work-up and monitoring of pulmonary infections may be perceived as invasive, is time consuming and expensive. In this explorative study, we investigated whether or not a non-invasive exhaled breath analysis using an electronic nose would discriminate between cystic fibrosis...... (CF) and primary ciliary dyskinesia (PCD) with or without various well characterized chronic pulmonary infections. We recruited 64 patients with CF and 21 with PCD based on known chronic infection status. 21 healthy volunteers served as controls. An electronic nose was employed to analyze exhaled......, this method significantly discriminates CF patients suffering from a chronic pulmonary P. aeruginosa (PA) infection from CF patients without a chronic pulmonary infection. Further studies are needed for verification and to investigate the role of electronic nose technology in the very early diagnostic workup...

    Chronic pain can be associated with movement abnormalities. The primary motor cortex (M1) has an essential role in the formulation and execution of movement. A number of changes in M1 function have been reported in studies of people with chronic pain. This review systematically evaluated the evidence for altered M1 structure, organization, and function in people with chronic pain of neuropathic and non-neuropathic origin. Database searches were conducted and a modified STrengthening the Reporting of OBservational studies in Epidemiology checklist was used to assess the methodological quality of included studies. Meta-analyses, including preplanned subgroup analyses on the basis of condition were performed where possible. Sixty-seven studies (2,290 participants) using various neurophysiological measures were included. There is conflicting evidence of altered M1 structure, organization, and function for neuropathic and non-neuropathic pain conditions. Meta-analyses provided evidence of increased M1 long-interval intracortical inhibition in chronic pain populations. For most measures, the evidence of M1 changes in chronic pain populations is inconclusive. This review synthesizes the evidence of altered M1 structure, organization, and function in chronic pain populations. For most measures, M1 changes are inconsistent between studies and more research with larger samples and rigorous methodology is required to elucidate M1 changes in chronic pain populations.

    Initial presentation with primary spinal involvement in chronic recurrent multifocal osteomyelitis of childhood (CRMO) is rare. Our objective was to review the imaging appearances of three patients who had CRMO who initially presented with isolated primary spinal involvement.Design and patients The imaging, clinical, laboratory and histology findings of the three patients were retrospectively reviewed. Imaging included seven spinal MR imaging scans, one computed tomography scan, nine bone scans, two tomograms and 16 radiographs. These were reviewed by two musculoskeletal radiologists and a consensus view is reported. All three patients presented with atraumatic spinal pain and had extensive bone spinal pathology. The patients were aged 11, 13 and 12 years. There were two females and one male.Results and conclusions The initial patient had thoracic T6 and T8 vertebra plana. Bone scan showed additional vertebral body involvement. Follow-up was available over a 3 year period. The second patient had partial collapse of T9 and, 2 years later, of C6. Subsequently extensive multifocal disease ensued and follow-up was available over 8 years. The third patient initially had L3 inferior partial collapse and 1 year later T8 involvement with multifocal disease. Follow-up was available over 3 years. The imaging findings of the three patients include partial and complete vertebra plana with a subchondral line adjacent to endplates associated with bone marrow MR signal alterations. Awareness of the imaging appearances may help the radiologist to include this entity in the differential diagnosis in children who present with spinal pathology and no history of trauma. Histopathological examination excludes tumor and infection but with typical imaging findings may not always be necessary. (orig.)

    The coexistence of chronic autoimmune atrophic gastritis (CAAG) and primary hyperparathyroidism (PHPT) has been described previously, even if its extent and underlying mechanisms remain poorly understood. We therefore prospectively evaluated this association in two series of patients, one with CAAG and the other with sporadic PHPT. From January 2005 to March 2012, 107 histologically confirmed CAAG patients and 149 PHPT patients were consecutively enrolled. Routine laboratory assays included serum calcium, parathyroid hormone (PTH), plasma gastrin and chromogranin A (CgA). In CAAG patients with high PTH levels, ionized calcium and 25(OH)-vitamin D were evaluated. All CAAG and hypergastrinemic PHPT patients received an upper gastrointestinal endoscopy. Exclusion criteria were familial PHPT, MEN1 syndrome, treatment with proton pump inhibitor drugs, Helicobacter pylori infection and renal failure. Of the 107 CAAG patients, nine (8.4%) had PHPT and 13 (12.1%) had secondary hyperparathyroidism stemming from vitamin D deficiency. Among the 149 PHPT patients, 11 (7.4%) had CAAG. Gastrin and CgA levels were similar in the CAAG patients with vs those without hyperparathyroidism (either primary or secondary), and calcium and PTH levels were similar in the PHPT patients with vs those without CAAG. This study confirms a non-casual association between PHPT and CAAG. The prevalence of PHPT in CAAG patients is threefold that of the general population (8.4 vs 1-3%), and the prevalence of CAAG in PHPT patients is fourfold that of the general population (7.4 vs 2%). The mechanisms underlying this association remain unknown, but a potential role for autoimmunity is suggested.

    To determine the prevalence of chronic fatigue syndrome (CFS) and of primary fibromyalgia syndrome (PFS) in the Netherlands. Questionnaire. Department of Medical Psychology, University Hospital Nijmegen, the Netherlands. A questionnaire was mailed to all the 6657 general practitioners in the Netherlands in order to inform them of the existence of CFS and to ask them if they had any CFS or PFS patients in their practices. Sixty percent (n = 4027) of the general practitioners returned the questionnaire. Of all the general practitioners, 27% said they had no CFS patients, 23% said they had 1 CFS patient, while 21% had 2 CFS patients, and 29% said they had 3 or more CFS patients in their practice. Concerning PFS the results were 17% (no PFS patients), 18%, 18% and 47%, respectively. With a mean practice of 2486 patients per general practice, the estimated prevalence of CFS was 112 per 100,000 and that of PFS 157 per 100,000 persons. Of the CFS patients 81% were women and 55% were 25-44 years old; for PFS these figures were 87% and 48% respectively. Extrapolation of the study results indicates that there are at least 17,000 CFS patients and 24,000 PFS patients in the Netherlands. The found prevalence is probably an under-estimation.

Average quality of the CPG was 57.2%; low rating in domains: "Applicability" (<25%), "Stakeholder involvement" (43.5%) and "Rigour of development" (55.0%). Compliance in CS ranges from 39 to 53.4%. Professionals show uneven knowledge of CPG; 44 to 45% (according to CPG), they declare that they are not used, they identify as main barriers the lack of training, and their difficult accessibility and management. The quality and implementation of evaluated CPG is deficient constituting an opportunity of improvement in health services.

    Full Text Available To mimic multilevel nerve root compression and intervertebral foramina stenosis in human, we established a new animal model of the chronic compression of unilateral multiple lumbar DRGs (mCCD in the rat. A higher occurrence of signs of spontaneous pain behaviors, such as wet-dog shaking and spontaneous hind paw shrinking behaviors, was firstly observed from day 1 onward. In the meantime, the unilateral mCCD rat exhibited significant bilateral hind paw mechanical and cold allodynia and hyperalgesia, as well as a thermal preference to 30°C plate between 30 and 35°C. The expression of activating transcription factor 3 (ATF3 was significantly increased in the ipsilateral and contralateral all-sized DRG neurons after the mCCD. And the expression of CGRP was significantly increased in the ipsilateral and contralateral large- and medium-sized DRG neurons. ATF3 and CGRP expressions correlated to evoked pain hypersensitivities such as mechanical and cold allodynia on postoperative day 1. The results suggested that bilateral neuropathy of primary sensory neurons might contribute to bilateral hypersensitivity in the mCCD rat.

    Background An integrated chronic disease management (ICDM) model consisting of four components (facility reorganisation, clinical supportive management, assisted self-supportive management and strengthening of support systems and structures outside the facility) has been implemented across 42 primary health care clinics in South Africa with a view to improve the operational efficiency and patient clinical outcomes. Aim The aim of this study was to assess the sustainability of the facility reorganisation and clinical support components 18 months after the initiation. Setting The study was conducted at 37 of the initiating clinics across three districts in three provinces of South Africa. Methods The National Health Service (NHS) Institute for Innovation and Improvement Sustainability Model (SM) self-assessment tool was used to assess sustainability. Results Bushbuckridge had the highest mean sustainability score of 71.79 (95% CI: 63.70–79.89) followed by West Rand Health District (70.25 (95% CI: 63.96–76.53)) and Dr Kenneth Kaunda District (66.50 (95% CI: 55.17–77.83)). Four facilities (11%) had an overall sustainability score of less than 55. Conclusion The less than optimal involvement of clinical leadership (doctors), negative staff behaviour towards the ICDM, adaptability or flexibility of the model to adapt to external factors and infrastructure limitation have the potential to negatively affect the sustainability and scale-up of the model.

    The aim of this study was to describe chronic pain self-management from the perspective of individuals living with chronic pain in the context of primary care nursing. Self-management is a key chronic pain treatment modality and support for self-managing chronic pain is mainly provided in the context of primary care. Although nurses are optimally suited to facilitate self-management in primary care, there is a need to explore opportunities for optimizing their roles. Two cross-sectional studies. The Chronic Pain Self-Management Survey was conducted in 2011-2012 to explore the epidemiology and self-management of chronic pain in Canadian adults. The questionnaire was distributed to 1504 individuals in Ontario. In 2011, the Primary Care Nursing Roles Survey was distributed to 1911 primary care nurses in Ontario to explore their roles and to determine the extent to which chronic disease management strategies, including support for self-management, were implemented in primary care. Few respondents to the pain survey identified nurses as being the 'most helpful' facilitator of self-management while physicians were most commonly cited. Seventy-six per cent of respondents used medication to manage their chronic pain. Few respondents to the nursing survey worked in practices with specific programmes for individuals with chronic pain. Individuals with chronic pain identified barriers and facilitators to self-managing their pain and nurses identified barriers and facilitators to optimizing their role in primary care. There are several opportunities for primary care practices to facilitate self-management of chronic pain, including the optimization of the primary care nursing role. © 2015 John Wiley & Sons Ltd.

    To explore the feasibility and acceptability of nurse-led chronic disease management and lifestyle risk factor reduction interventions in primary care (general practice/family practice). Growing international evidence suggests that interventions delivered by primary care nurses can assist in modifying lifestyle risk factors and managing chronic disease. To date, there has been limited exploration of the feasibility and acceptability of such interventions. Integrative review guided by the work of Whittemore and Knafl (). Database search of CINAHL, Medline and Web of Science was conducted to identify relevant literature published between 2000-2015. Papers were assessed for methodological quality and data abstracted before thematic analysis was undertaken. Eleven papers met the inclusion criteria. Analysis uncovered four themes: (1) facilitators of interventions; (2) barriers to interventions; (3) consumer satisfaction; and (4) primary care nurse role. Literature supports the feasibility and acceptability of nurse-led interventions in primary care for lifestyle risk factor modification. The ongoing sustainability of these interventions rests largely on organizational factors such as funding, educational pathways and professional support of the primary care nursing role. Further robust research around primary care nurse interventions is required to strengthen the evidence base. © 2017 John Wiley & Sons Ltd.

    Full Text Available Background: Deficiencies in record keeping practices have been reported at primary care level in the public health sector in South Africa. These deficiencies have the potential to negatively impact patient health outcomes as the break in information may hinder continuity of care. This disruption in information management has particular relevance for patients with chronic diseases. Objectives: The aim of this study was to establish if the implementation of a structured clinical record (SCR as an adjunct tool to the algorithmic guidelines for chronic disease management improved the quality of clinical records at primary care level. Method: A quasi-experimental study (before and after study with a comparison group was conducted across 30 primary health care clinics (PHCs located in three districts in South Africa. Twenty PHCs that received the intervention were selected as intervention clinics and 10 facilities were selected as comparison facilities. The lot quality assurance sampling (LQAS method was used to determine the number of records required to be reviewed per diagnostic condition per facility. Results: There was a a statistically significant increase in the percentage of clinical records achieving compliance to the minimum criteria from the baseline to six months post-intervention for both HIV patients on antiretroviral treatment and patients with non-communicable diseases (hypertension and diabetes. Conclusions: A multifaceted intervention using a SCR to supplement the educational outreach component (PC 101 training has demonstrated the potential for improving the quality of clinical records for patients with chronic diseases at primary care clinics in South Africa.

    Full Text Available Chronic kidney disease (CKD is commonly managed in primary care, but most guidelines have a secondary care perspective emphasizing the risk of end-stage kidney disease (ESKD and need for renal replacement therapy. In this prospective cohort study, we sought to study in detail the natural history of CKD in primary care to better inform the appropriate emphasis for future guidance.In this study, 1,741 people with CKD stage 3 were individually recruited from 32 primary care practices in Derbyshire, United Kingdom. Study visits were undertaken at baseline, year 1, and year 5. Binomial logistic regression and Cox proportional hazards models were used to model progression, CKD remission, and all-cause mortality. We used Kidney Disease: Improving Global Outcomes (KDIGO criteria to define CKD progression and defined CKD remission as the absence of diagnostic criteria (estimated glomerular filtration rate [eGFR] >60 ml/min/1.73 m2 and urine albumin-to-creatinine ratio [uACR] <3 mg/mmol at any study visit. Participants were predominantly elderly (mean ± standard deviation (SD age 72.9 ± 9.0 y, with relatively mild reduction in GFR (mean ± SD eGFR 53.5 ± 11.8 mL/min/1,73 m2 and a low prevalence of albuminuria (16.9%. After 5 y, 247 participants (14.2% had died, most of cardiovascular causes. Only 4 (0.2% developed ESKD, but 308 (17.7% evidenced CKD progression by KDIGO criteria. Stable CKD was observed in 593 participants (34.1%, and 336 (19.3% met the criteria for remission. Remission at baseline and year 1 was associated with a high likelihood of remission at year 5 (odds ratio [OR] = 23.6, 95% CI 16.5-33.9 relative to participants with no remission at baseline and year 1 study visits. Multivariable analyses confirmed eGFR and albuminuria as key risk factors for predicting adverse as well as positive outcomes. Limitations of this study include reliance on GFR estimated using the Modification of Diet in Renal Disease study (MDRD equation for

    Full Text Available Abstract Background The diagnosis and treatment of patients with chronic obstructive pulmonary disease (COPD in Spain continues to present challenges, and problems are exacerbated when there is a lack of coordinated follow-up between levels of care. This paper sets out the protocol for assessing the impact of an integrated management model for the care of patients with COPD. The new model will be evaluated in terms of 1 improvement in the rational utilization of health-care services and 2 benefits reflected in improved health status and quality of life for patients. Methods/Design A quasi-experimental study of the effectiveness of a COPD management model called COPD PROCESS. The patients in the study cohorts will be residents of neighborhoods served by two referral hospitals in Barcelona, Spain. One area comprises the intervention group (n = 32,248 patients and the other the control group (n = 32,114 patients. The study will include pre- and post-intervention assessment 18 months after the program goes into effect. Analyses will be on two datasets: clinical and administrative data available for all patients, and clinical assessment information for a cohort of 440 patients sampled randomly from the intervention and control areas. The main endpoints will be the hospitalization rates in the two health-care areas and quality-of-life measures in the two cohorts. Discussion The COPD PROCESS model foresees the integrated multidisciplinary management of interventions at different levels of the health-care system through coordinated routine clinical practice. It will put into practice diagnostic and treatment procedures that are based on current evidence, multidisciplinary consensus, and efficient use of available resources. Care pathways in this model are defined in terms of patient characteristics, level of disease severity and the presence or absence of exacerbation. The protocol covers the full range of care from primary prevention to treatment of

    Chronic kidney disease (CKD) has become a significant part of the GP's workload since the introduction of the National Institute for Health and Care Excellence guidelines in 2008. Patients with advanced CKD (stages G4 and G5) often have comorbidities, varied disease progression, and are likely to be older. GPs may experience difficulties with management decisions for patients with advanced CKD, including when to refer to nephrology. To explore GPs' views of managing patients with advanced CKD and referral to secondary care. Qualitative study with GPs in four areas of England: London, Bristol, Birmingham, and Stevenage. Semi-structured interviews with 19 GPs. Transcribed interviews were thematically analysed. GPs had little experience of managing patients with advanced CKD, including those on dialysis or having conservative care (treatment without dialysis or a transplant), and welcomed guidance. Some GPs referred patients based on renal function alone and some used wider criteria including age and multimorbidity. GPs reported a tension between national guidance and local advice, and some had learnt from experience that patients were discharged back to primary care. GPs with more experience of managing CKD referred patients later, or sometimes not at all, if there were no additional problems and if dialysis was seen as not in the patient's interests. GPs want guidance on managing older patients with advanced CKD and comorbidities, which better incorporates agreement between local and national recommendations to clarify referral criteria. GPs are not generally aware of conservative care programmes provided by renal units, however, they appear happy to contribute to such care or alternatively, lead conservative management with input from renal teams. © British Journal of General Practice 2015.

    In this article, the relationship between mental health and chronic non-communicable diseases is discussed as well as the possibility to address them in a comprehensive manner in the Peruvian health system. First, the prevalence estimates and the burden of chronic non-communicable diseases and mental disorders worldwide and in Peru are reviewed. Then, the detrimental impact of depression in the early stages as well as the progress of diabetes and cardiovascular diseases is described. Additionally, the gap between access to mental health care in Peru is analyzed. Lastly, the alternatives to reduce the gap are explored. Of these alternatives, the integration of mental health into primary care services is emphasized; as a feasible way to meet the care needs of the general population, and people with chronic diseases in particular, in the Peruvian context.

    Full Text Available Treatment of chronic pain is challenging. The Arkys project was initiated in Italy to assist general practitioners (GPs in the management of chronic pain. The main objective of this study was to determine the usefulness of Arkys for selecting new therapeutic strategies. An online interactive questionnaire for assessing pain and guiding therapeutic decisions was made available to GPs participating to Arkys. The GPs were invited to complete the questionnaire for each patient who presented moderate-severe chronic pain, and to decide on a new analgesic treatment based on the information provided by the questionnaire. Two hundred and forty four GPs participated with a total of 3035 patients. Patients (mean age 68.9 years had mostly chronic non-cancer pain (87.7%. In 42.3%, pain had neuropathic components. Only 53.6% of patients were in treatment with analgesics (strong opioids, 38.9%; NSAIDs, 32.6%; weak opioids, 25.6%; anti-epileptics, 17.3%; paracetamol, 14.9%. Use of the questionnaire resulted in the prescription of analgesics to all patients and in increased prescription of strong opioids (69.7%. NSAID prescription decreased (12.8%, while anti-epileptics use remained stable. These findings show that current management of chronic pain in primary care is far from optimal and that efforts are needed to educate GPs and improve guideline implementation.

    This study aims to investigate the usefulness of (18)F-FDG PET/CT for distinguishing between primary thyroid lymphoma (PTL) and chronic thyroiditis. We retrospectively reviewed the data of 196 patients with diffuse (18)F-FDG uptake of the thyroid gland and enrolled patients who were diagnosed as having PTL or chronic thyroiditis based on the medical records, pathological findings, and laboratory data. The enrolled patients comprised 10 PTL patients (M/F = 4:6) and 51 chronic thyroiditis patients (M/F = 8:43). Images had been acquired on a PET/CT scanner at 100 minutes after intravenous injection of (18)F-FDG. The PTL group consisted of 7 patients with diffuse large B-cell lymphoma (DLBCL) and 3 with mucosa-associated lymphoid tissue (MALT) lymphoma. The maximum standardized uptake value (SUV(max)) was significantly higher in the PTL group than that in the chronic thyroiditis group (25.3 ± 8.0 and 7.4 ± 3.2, P thyroiditis group (46.1 ± 7.0 HU and 62.1 ± 6.9 HU, P thyroiditis. Thus, (18)F-FDG PET/CT may be useful for distinguishing between PTL and chronic thyroiditis.

    to assess the structure and results obtained by the "Chronic Renal Patients Care Program" in a Brazilian city. epidemiological, cross-sectional study conducted in 14 PHC units and a secondary center from 2010 to 2013. The Donabedian Model was the methodological framework used. A total of 14 physicians, 13 supervisors, and 11 community health agents from primary healthcare were interviewed for the assessment of structure and process and 1,534 medical files from primary healthcare and 282 from secondary care were consulted to assess outcomes. most units lacked sufficient offices for physicians and nurses to provide consultations, had incomplete staffing, and most professionals had not received proper qualification to provide care for chronic renal disease. Physicians from PHC units classified as capable more frequently referred patients to the secondary care service in the early stages of chronic renal disease (stage 3B) when compared to physicians of units considered not capable (58% vs. 36%) (p=0.049). Capable PHC units also more frequently presented stabilized glomerular filtration rates (51%) when compared to partially capable units (36%) and not capable units (44%) (p=0.046). patients cared for by primary healthcare units that scored higher in structure and process criteria presented better clinical outcomes. to identify the coping strategies of family members of patients with mental disorders and relate them to family member sociodemographic variables and to the patient's clinical variables. this was a descriptive study conducted at a psychiatric hospital in the interior of the state of São Paulo, with 40 family members of hospitalized patients over the age of 18, and who followed the patient before and during hospitalization. We used tools to characterize the subjects and the Folkman and Lazarus Inventory of Coping Strategies. the coping strategies most often used by family members were social support and problem solving.

    Prior studies have underlined the need for increased screening and awareness of chronic hepatitis B (CHB), especially in certain high-risk populations. However, few studies have examined the patterns of evaluation and management of CHB between primary care physicians (PCP) and specialists according to commonly-used professional guidelines. Our goal was to examine whether necessary laboratory parameters used to determine disease status and eligibility for antiviral therapy were performed by PCPs and specialists. We conducted a retrospective study of 253 treatment-naïve CHB patients who were evaluated by PCP only (n=63) or by specialists (n=190) for CHB at a community multispecialty medical center between March 2007 and June 2009. Criteria for CHB management and treatment eligibility were based on the American Association for the Study of Liver Diseases 2007 guideline and the US Panel 2006 algorithm. Required parameters for optimal evaluation for CHB included hepatitis B e antigen (HBeAg), HBV DNA, and alanine aminotransferase (ALT). Preferred antiviral agents for CHB included pegylated interferon, adefovir, and entecavir. The majority of patients were Asians (90%) and (54%) with a mean age of 43±11.6 years. Compared to PCPs, specialists were more likely to order laboratory testing for ALT (94 vs. 86%, P=0.05), HBeAg (67 vs. 41%, P<0.0001) and HBV DNA (83 vs. 52%, P<0.0001). The proportion of patients having all three laboratory parameters was significantly higher among those evaluated by specialists compared to PCP (62 vs. 33%, P<0.0001). A total of 55 patients were initiated on antiviral treatment (n=47 by specialists and n=6 by PCPs). Lamivudine was prescribed more often by PCPs than specialists (33 vs. 2%, P=0.05). Preferred agents were used 96% of the time by specialists compared to 67% of those treated by PCPs (P=0.05). Patients evaluated by specialists for CHB are more likely to undergo more complete laboratory evaluation and, if eligible, are also more

    Objective The study aimed to determine the impact of the Flinders Chronic Condition Management Program for chronic condition self-management care planning and how to improve its use with Bendigo Health's Hospital Admission Risk Program (HARP). Methods A retrospective analysis of hospital admission data collected by Bendigo Health from July 2012 to September 2013 was undertaken. Length of stay during admission and total contacts post-discharge by hospital staff for 253 patients with 644 admissions were considered as outcome variables. For statistical modelling we used the generalised linear model. Results The combination of the HARP and Flinders Program was able to achieve significant reductions in hospital admissions and non-significant reduction in emergency department presentations and length of stay. The generalised linear model predicted that vulnerable patient groups such as those with heart disease (P=0.037) and complex needs (Pmanage chronic conditions through a greater focus on coordination and integration of care across primary care and hospital systems. In support of HARP, self-management interventions such as the Flinders Program aim to help individuals better manage their medical treatment and cope with the impact of the condition on their physical and mental wellbeing and thus reduce health services utilisation. What does this paper add? This paper sheds light on which patients might be more or less likely to benefit from the combination of the HARP and Flinders Program, with regard to their impact on reductions in hospital admissions, emergency department presentations and length of stay. This study also sheds light on how the Flinders Program could be better targeted towards and implemented among high-need and high-cost patients to lessen chronic disease burden on Australia's health system. What are the implications for practitioners? Programs targeting vulnerable populations and applying evidence-based chronic condition management and self

    The objectives of this paper are to describe the planned implementation and evaluation of the Building on Existing Tools to Improve Chronic Disease Prevention and Screening in Primary Care (BETTER 2) program which originated from the BETTER trial. The pragmatic trial, informed by the Chronic Care Model, demonstrated the effectiveness of an approach to Chronic Disease Prevention and Screening (CDPS) involving the use of a new role, the prevention practitioner. The desired goals of the program are improved clinical outcomes, reduction in the burden of chronic disease, and improved sustainability of the health-care system through improved CDPS in primary care. The BETTER 2 program aims to expand the implementation of the intervention used in the original BETTER trial into communities across Canada (Alberta, Ontario, Newfoundland and Labrador, the Northwest Territories and Nova Scotia). This proactive approach provides at-risk patients with an intervention from the prevention practitioner, a health-care professional. Using the BETTER toolkit, the prevention practitioner determines which CDPS actions the patient is eligible to receive, and through shared decision-making and motivational interviewing, develops a unique and individualized 'prevention prescription' with the patient. This intervention is 1) personalized; 2) addressing multiple conditions; 3) integrated through linkages to local, regional, or national resources; and 4) longitudinal by assessing patients over time. The BETTER 2 program brings together primary care providers, policy/decision makers and researchers to work towards improving CDPS in primary care. The target patient population is adults aged 40-65. The reach, effectiveness, adoption, implementation, maintain (RE-AIM) framework will inform the evaluation of the program through qualitative and quantitative methods. A composite index will be used to quantitatively assess the effectiveness of the prevention practitioner intervention. The CDPS actions

To collect the data, 38 interviews were held with health professionals and managers; observation of the activities by the health teams; and analysis of 25 files of people who received this care. The data analysis was supported by the software ATLAS.ti, using the directed content analysis technique. at the micro level, care was distant from the integrality of the actions needed to assist people with chronic conditions and was centered on the biomedical model. At the meso level, there was disarticulation among the professionals of the Family Health Strategy, between them and the users, family and community. At the macro level, there was a lack of guiding strategies to implement public policies for diabetes in care practice. the implementation of the Modelo de Atenção às Condições Crônicas represents a great challenge, mainly needing professionals and managers who are prepared to work with chronic conditions are who are open to break with the traditional model. evaluar la atención de salud desarrollada por los integrantes de la Atención Primaria de Salud a las personas con diabetes mellitus en la perspectiva del Modelo de Atenção às Condições Crônicas. estudio cualitativo, con referencial teórico del Pensamiento Complejo y del Modelo de Atenção às Condições Crônicas y metodológico de la investigación evaluativa.

    Uzbekistan has a well-developed primary care system, with universal access to care, but faces challenges in improving the quality of clinical care provided. This study aimed to identify barriers to quality improvement by focusing on one common condition, Chronic Heart Failure (CHF), for which there are evidence-based international guidelines for management. To identify the challenges to improving the quality of care for CHF in line with such guidelines we took a qualitative approach, interviewing 15 physicians and 30 patients in detail about their experiences of CHF management. Despite recent improvements to the training of primary care physicians, their access to up-to-date information was limited, and they were disproportionately reliant on information from pharmaceutical companies. The main barriers to implementing international standards of care were: reluctance of physicians (and patients) to abandon ineffective interventions; enduring, system-wide incentives for clinically unnecessary hospitalization; and the lack of structural support for evidence-based health services improvement. Patients were in general positive about adherence to medications, but faced some problems in affording drugs and hospital care. Future interventions to strengthen primary care should be implemented with evaluations of their impact on the processes and outcomes of care for chronic conditions.

    Primary care physicians play an important role in the diagnosis and management of depression. Yet little is known about their use of care management processes for depression. Using national survey data for the period 2006-13, we assessed the use of five care management processes for depression and other chronic illnesses among primary care practices in the United States. We found significantly less use for depression than for asthma, congestive heart failure, or diabetes in 2012-13. On average, practices used fewer than one care management process for depression, and this level of use has not changed since 2006-07, regardless of practice size. In contrast, use of diabetes care management processes has increased significantly among larger practices. These findings may indicate that US primary care practices are not well equipped to manage depression as a chronic illness, despite the high proportion of depression care they provide. Policies that incentivize depression care management, including additional quality metrics, should be considered. Project HOPE—The People-to-People Health Foundation, Inc.

    Cigarette smoking has been associated with multiple negative effects on human skin. Long-term physiological effects of cigarette smoke are through chronic and not acute exposure. Molecular alterations due to chronic exposure to cigarette smoke remain unclear. Primary human skin keratinocytes chronically exposed to cigarette smoke condensate (CSC) showed a decreased wound-healing capacity with an increased expression of NRF2 and MMP9. Using quantitative proteomics, we identified 4728 proteins, of which 105 proteins were overexpressed (≥2-fold) and 41 proteins were downregulated (≤2-fold) in primary skin keratinocytes chronically exposed to CSC. We observed an alteration in the expression of several proteins involved in maintenance of epithelial barrier integrity, including keratin 80 (5.3 fold, p value 2.5 × 10 -7 ), cystatin A (3.6-fold, p value 3.2 × 10 -3 ), and periplakin (2.4-fold, p value 1.2 × 10 -8 ). Increased expression of proteins associated with skin hydration, including caspase 14 (2.2-fold, p value 4.7 × 10 -2 ) and filaggrin (3.6-fold, p value 5.4 × 10 -7 ), was also observed. In addition, we report differential expression of several proteins, including adipogenesis regulatory factor (2.5-fold, p value 1.3 × 10 -3 ) and histone H1.0 (2.5-fold, p value 6.3 × 10 -3 ) that have not been reported earlier. Bioinformatics analyses demonstrated that proteins differentially expressed in response to CSC are largely related to oxidative stress, maintenance of skin integrity, and anti-inflammatory responses. Importantly, treatment with vitamin E, a widely used antioxidant, could partially rescue adverse effects of CSC exposure in primary skin keratinocytes. The utility of antioxidant-based new dermatological formulations in delaying or preventing skin aging and oxidative damages caused by chronic cigarette smoke exposure warrants further clinical investigations and multi-omics research.

    Lymphoma is a malignant neoplasm of component cells of the lymphoid system which is very rare in the jaws. Here we report a case of primary diffuse large B-cell lymphoma located in the periapical region of a mandibular molar which was misdiagnosed as chronic periapical periodontitis. The present case was diagnosed at an early stage and effectively managed by chemotherapy. Although lymphoma of the mandible is rare, it must be considered in the differential diagnosis of radiolucent lesions in this region. Lack of knowledge of this rare presentation may lead to delays in diagnosis and poor prognosis. © 2013 Australian Dental Association.

Basing on X-ray and morphological findings, the diagnosis was confirmed in 128 patients of the 1st group (68.2 %) and in 89 patients of the 2nd group (86 %). The primary double contrast study of the colon was found more effective as it permitted the detection of elements of the mucosal microcontours: transversal strips, not coinciding with haustration, focal granularity, diffuse granularity, small barium suspension depots or niches, nodular granularity. It permitted the recommendation of the method for a wide clinical use

    To determine the possible associations between higher levels of selected quality indicators and the characteristics of providers. In 2011, an ongoing project on a new model of family medicine practice was launched in Slovenia; the family physicians' working team (a family physician and a practice nurse) was extended by a nurse practitioner working 0.5 full-time equivalents. This was an example of a personalised team approach to managing chronic patients. We included all family medicine practices in the six units of the Community Health Centre Ljubljana which were participating in the project in December 2015 (N = 66). Data were gathered from automatic electronic reports on quality indicators provided monthly by each practice. We also collected demographic data. There were 66 family medicine teams in the sample, with 165 members of their teams (66 family physicians, 33 nurse practitioners and 66 practice nurses). Fifty-six (84.4%) of the family physicians were women, as were 32 (97.0%) of the nurse practitioners, and 86 (95.5%) of the practice nurses. Multivariate analysis showed that a higher level of the quality indicator "Examination of diabetic foot once per year" was independently associated with nurse practitioners having attended additional education on diabetes, duration of participation in the project, age and years worked since graduation of nurse practitioners, working in the Center unit and not working in the Bezigrad unit. Characteristics of team members are important in fostering quality management of chronic patients. Nurse practitioners working in new model family practices need obligatory, continuous professional education in the management of chronic patients. The quality of care of chronic patients depends on the specific characteristics of the members of the team, which should be taken into account when planning quality improvements. © 2017 John Wiley & Sons Ltd.

    To investigate community health worker (CHW) effects on chronic disease outcomes using electronic health records (EHRs). We examined EHRs of 32 147 patients at risk for chronic disease during 2012 to 2015. Variables included contact with clinic-based CHWs, vitals, and laboratory tests. We estimated a mixed model for all outcomes. Within-group findings showed statistically significant improvements in chronic disease indicators after exposure to CHWs. In health center 1, HbA1c (glycated hemoglobin) decreased 0.15 millimoles per mole (95% confidence interval [CI] = -0.24, -0.06), body mass index decreased 0.29 kilograms per meter squared (CI = -0.39, -0.20), and total cholesterol decreased 11.9 milligrams per deciliter (CI = -13.5, -10.2). In health center 2, HbA1c decreased 0.43 millimoles per mole (CI = -0.7, -0.17), body mass index decreased by 0.08 kilograms per meter squared (CI = -0.14, -0.02), and triglycerides decreased by 22.50 milligrams per deciliter (CI = -39.0, -6.0). Total cholesterol of 3.62 milligrams per deciliter (CI = -6.6, -0.6) in health center 1 was the only improvement tied to CHW contact. Although patients' chronic disease indicators consistently improved, between-group models provided no additional evidence of impact. EHRs' evolution may elucidate CHW contributions moving forward.

    Full Text Available The treatment of chronic obstructive pulmonary disease (COPD and comorbidities, increasing with age, is the challenge that nowadays health care systems are facing to better care treat these patients. For this reason a clinical trial was conducted in the province of Trento by a group of 30 volunteer general practitioners members of SNAMID (Scientific Society for Continuing Medical Education of General Practitioners. The objectives were to identify: i prevalence of COPD in patients (65-98 years in the province of Trento; ii presence and incidence of heart failure (HF in COPD patients; iii early detection of other chronic diseases; and iv improving electronic medical records (EMR as an innovation way of professional care management. From May 2011 to October 2013, 17 doctors completed the two-year work using the EMR. The studied patients were men and women (65-98 years, suffering from COPD; the considered data included: anthropometric information, smoking status, International Classification of Diseases (ICD-9 diagnosis of COPD, HF and chronic diseases, specific blood and instrumental tests. The extracted results were then linked with data of sentinel therapies, collected by the EMR. The database obtained identified patients with COPD or HF not previously recognized with ICD-9 diagnosis. The study identified the sentinel drugs chosen for COPD and HF, excluding other drugs not selective for the study or confusing for a proper statistical evaluation.

    Full Text Available Introduction. Secondary malignancies, particularly solid tumors, are common in patients with chronic lymphocytic leukemia (CLL, but association of myeloproliferative neoplasms and chronic lymphocytic leukemia in the same patient is very rare. Case Outline. We report of a 67-year-old man with B-cell chronic lymphoid leukemia (B-CLL who developed primary myelofibrosis (PMF nine years after initial diagnosis. Patient received alkylation agents and purine analogue, which can be a predisposing factor for the development of myeloproliferative neoplasms. JAK2V617F mutation was not present initially at the time of CLL diagnosis, but was found after nine years when PMF occurred, which indicates that B-CLL and PMF represent two separate clonal origin neoplasms. Conclusion. Pathogenic mechanisms for the development of myeloproliferative and lymphoproliferative neoplasms in the same patient are unknown. Further research is needed to determine whether these malignancies originate from two different cell clones or arise from the same pluripotent hematopoietic stem cell.

    This study explored the adequacy of depression screening in a community health center. The medical charts of individuals (N = 90) enrolled at a community health center were randomly selected, reviewed, and compared to current standard-of-care guidelines for four elements: family history, screening for depression, control of chronic illnesses, and missed opportunities for preventive care. Family history documentation collected by the providers was limited and 44.4% had no family history. There was no routine depression screening process, although 48.9% of the clients had red flags (warning signals) for depression. Laboratory values used for screening control of chronic disease in the medical records were: fasting glucose levels ⩽100 mg/dL (46%), total cholesterol levels ⩽200 mg/dL (38%), and blood pressure ⩽120/80 mmHg (23%). The results highlight the need to focus on depression screening as part of preventive care and the management of chronic disease in the primary care setting. Copyright 2013, SLACK Incorporated.

    2015-02-01

    Current scientific evidence on the management of chronic non-specific low back pain highlights the benefits of physical exercise. This goal is frequently undermined due to lack of education of the subjects on the multifactorial, benign, and non-specific nature of low back pain, which can lead to a chronic disease with genuine psychosocial risk factors. Its influence may not only interfere with individual decision to adopt more adaptive coping behaviors, but also with the endogenous mechanisms of pain neuromodulation. Thus, the educational strategies and control of these factors have become important objectives to be incorporated into the management of the disorder and research guidelines. This paper presents the theoretical models and the scientific basis on which it has based the design of an educational tool for patients with chronic non-specific low back pain treated in Primary Care physiotherapy. Structure, content and objectives are also presented. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

    Recently, there has been dramatic increase in the diagnosis and pharmaceutical management of common chronic illnesses. Using qualitative data collected in primary care clinics, we assessed how these trends play out in clinical care. This qualitative study focused on management of type 2 diabetes and hypertension in 44 primary care clinics in Michigan and was based on interviews with 58 clinicians and 70 of their patients, and observations of 107 clinical consultations. We assessed clinicians' treatment strategies and discussions of factors influencing treatment decisions, and patients' understandings and experiences in managing these illnesses. Clinicians focused on helping patients achieve test results recommended by national guidelines, and most reported combining 2 or more medications per condition to reach targets. Medication selection and management was the central focus of the consultations we observed. Polypharmacy was common among patients, with more than one-half taking 5 or more medications. Patient interviews indicated that heavy reliance on pharmaceuticals presents challenges to patient well-being, including financial costs and experiences of adverse health effects. Factors promoting heavy use of pharmaceuticals include lower diagnostic and treatment thresholds, clinician-auditing and reward systems, and the prescribing cascade, whereby more medications are prescribed to control the effects of already-prescribed medications. We present a conceptual model, the inverse benefit law, to provide insight into the impact of pharmaceutical marketing efforts on the observed trends. We make recommendations about limiting the influence of the pharmaceutical industry on clinical practice, toward improving the well-being of patients with chronic illness.

    The appropriate use of pharmacological treatment according to the indications in Clinical Guidelines reduces morbidity and mortality in patients with chronic heart failure (CHF). There are numerous studies regarding this in the hospital environment, but there are few studies done in Primary Care. The objective of this study is to evaluate the degree of compliance by Primary Care doctors to the Clinical Guidelines of the European Society of Cardiology in patients with CHF. A descriptive, observational study on the use of indication-prescription drugs was conducted. Primary Care teams of the Leon Health Area (9 urban and 19 rural). The study population included patients with a diagnosis of New York Heart Association (NYHA) Grade II-IV chronic heart failure, from a register of 2047 with chronic heart failure patients treated by 97 Primary Care doctors. A proportional representative random sample of 474 patients from the urban and rural areas was studied. Adherence to the drugs recommended in the Clinical Guidelines was evaluated using two indicators; one overall, and another for drugs with a higher level of evidence (A1: angiotensin converting enzyme inhibitors-angiotensin II receptor antagonists [ACE-I/ARA-II], β-blockers [BB] and spironolactone). A total of 456 patients were studied, with a mean age of 78.4 years, and 53.1% females. Arterial hypertension (AHT) and ischaemic heart disease were present in 64.7% of patients. The mean comorbidity rate, excluding CHF, was 2.9. Around 40% were diagnosed a NYHA Grade 11-1V. The overall compliance rate (diuretics, ACE-I/ARA-II, β-blockers, spironolactone, digoxin, and oral anticoagulants) and rate of adherence to evidence-based ones was 55.2% and 44.6%, respectively. There was low compliance by 39.5%, and only 12.9% of patients showed perfect compliance with the drugs with a higher level of evidence, while to be less than 70 years-old, a history of ischaemia, AHT, and a hospital admission, were variables associated with

    Early detection of long term conditions is predicated on assumptions that lifestyle changes and medications can be used to reduce or manage the risk of condition progression. However, ambiguity remains about the nature and place of diagnostic disclosure to people in newly recognised or asymptomatic 'pre' conditions such as early stage chronic kidney disease (CKD). The disclosure of a diagnosis is relevant to instigating strategies which rely on actively engaging patients as self-managers of their own care. Whilst primary care routinely records a diagnosis of early stage CKD, little is known about how patients learn about the fact that they have CKD or how they respond to this. This study aimed to explore patients' experiences of disclosure of CKD in primary care settings. A nested qualitative study of participants recruited to a trial of an intervention for CKD patients in Greater Manchester, UK was undertaken. A purposive sample of 26 patients, with a mean age of 72 years (range 59-89, median 71), were interviewed during 2012. Interview transcripts were analysed using constant comparative techniques. Narrative accounts reflected limited or partial disclosure of CKD; often cast in vague terms as "nothing to worry about". How patients described themselves in terms of participation and their tendencies towards 'active' or 'passive' involvement in consultations emerged as important components of narratives around disclosure. The findings illuminate the ways in which diagnosis is oriented in a context where it is possible to meet the requirements for remuneration under a pay for performance system of primary care, whilst apparently not disclosing a label or a diagnosis to patients. This challenges the presumptions inherent in wider health policy objectives that are increasingly built on the notion of responsible patients and the ethos of the active support of self-management for pre-conditions.

    Background Anaemia is a known risk factor for cardiovascular disease and treating anaemia in chronic kidney disease (CKD) may improve outcomes. However, little is known about the scope to improve primary care management of anaemia in CKD. Methods An observational study (N = 1,099,292) with a nationally representative sample using anonymised routine primary care data from 127 Quality Improvement in CKD trial practices (ISRCTN5631023731). We explored variables associated with anaemia in CKD: eGFR, haemoglobin (Hb), mean corpuscular volume (MCV), iron status, cardiovascular comorbidities, and use of therapy which associated with gastrointestinal bleeding, oral iron and deprivation score. We developed a linear regression model to identify variables amenable to improved primary care management. Results The prevalence of Stage 3–5 CKD was 6.76%. Hb was lower in CKD (13.2 g/dl) than without (13.7 g/dl). 22.2% of people with CKD had World Health Organization defined anaemia; 8.6% had Hb ≤ 11 g/dl; 3% Hb ≤ 10 g/dl; and 1% Hb ≤ 9 g/dl. Normocytic anaemia was present in 80.5% with Hb ≤ 11; 72.7% with Hb ≤ 10 g/dl; and 67.6% with Hb ≤ 9 g/dl; microcytic anaemia in 13.4% with Hb ≤ 11 g/dl; 20.8% with Hb ≤ 10 g/dl; and 24.9% where Hb ≤ 9 g/dl. 82.7% of people with microcytic and 58.8% with normocytic anaemia (Hb ≤ 11 g/dl) had a low ferritin (stores may be depleted in over >60% of people with normocytic anaemia. Prescribing oral iron has not corrected anaemia. PMID:23351270

    Patients with chronic kidney disease have a high disease burand may benefit from primary care services and care coord A medical home model with direct access to primary care services is one approach that may address this need, yet has not been examined. As a substudy of the Patient-Centered Outcomes Research Institute (PCORI) patient-centered medical home for kidney disease (PCMH-KD) health system intervention study, we examined the uptake of free primary care physician (PCP) services. The PCORI PCMH-KD study was an initial step toward integrating PCPs, a nurse coordinator, a pharmacist, and community health workers (CHWs) within the health care delivery team. Adult chronic hemodialysis (CHD) at two urban dialysis centers were enrolled in the intervention. We examined trends and factors associated with the use of the PCMH-KD PCP among two groups of patients based on their report of having a regular physician for at least six months (established-PCP) or not (no-PCP). Of the 173 enrolled patients, 91 (53%) patients had at least one visit with the PCMH-KD PCP. The rate of visits was higher in those in the no-PCP group compared with those in the established-PCP group (62% vs. 41%, respectively). Having more visits with the CHW was positively associated with having a visit with the PCMH-KD PCPs for both groups. Embedded CHWs within the care team played a role in facilithe uptake of PCMH-KD PCP. Lessons from this health system intervention can inform future approaches on the integration of PCPs and care coordination for CHD patients.

    The cause of severe diarrhea in patients with systemic amyloidosis is obscure. We therefore performed pathophysiological studies in three such patients in an effort to determine the mechanism of amyloid diarrhea. Epithelial cell absorption rate of electrolytes was measured during steady state GI perfusion of a saline-mannitol solution. GI transit time of PEG and absorption of radiolabeled bile acid were measured simultaneously while subjects ingested three meals per day. To obtain a diarrhea control group for transit time and bile acid absorption, normal subjects were studied when they had diarrhea caused by ingestion of Milk of Magnesia (MOM). Diarrhea could not be explained by malabsorption of ingested nutrients, bacterial overgrowth, bile acid malabsorption, or epithelial cell malabsorption of electrolytes. However, 25% of polyethylene glycol (PEG) ingested with a standard meal was recovered in stool in 45 min, which is 10 times faster than in normal subjects with equally severe diarrhea caused by ingestion of MOM. All of the patients had autonomic neuropathy that remained unrecognized for 15-36 months after onset of chronic diarrhea; it seems likely that this was the cause of rapid transit. Severe chronic diarrhea in three patients with systemic amyloidosis was mediated by extremely rapid transit of chyme and digestive secretions through the intestine.

    Human epidermal keratinocytes are currently established as a treatment for burns and wounds and have laboratory applications. Keratinocyte culture contamination by unwanted cells and inhibition of cell proliferation are barriers in primary keratinocyte culture. According to the recent literature, these cells are hard to culture. The present study was conducted to evaluate the efficacy of gelatin-coated surfaces in keratinocyte cultures. After enzymatic isolation of keratinocytes from normal epidermis by trypsin, the cells were cultured on gelatin-coated flasks in serum-free medium. Another group of cells were cultured as a control group without gelatin coating. We showed positive effects of surface coating with gelatin on the primary culture of keratinocytes. Culture of these cells on a gelatincoated surface showed better proliferation with suitable morphology. By using gelatin, adhesion of these cells to the surface was more efficient and without contamination by small round cells. Successful primary culture of keratinocytes on a gelatin-coated surface may provide better yield and optimal number of cells for research and clinical applications.

    In the UK, primary care records are electronic and require doctors to ascribe disease codes to direct care plans and facilitate safe prescribing. We investigated factors associated with coding of chronic kidney disease (CKD) in patients with reduced kidney function and the impact this has on patient management. We identified patients meeting biochemical criteria for CKD (two estimated glomerular filtration rates 90 days apart) from 1039 general practitioner (GP) practices in a UK audit. Clustered logistic regression was used to identify factors associated with coding for CKD and improvement in coding as a result of the audit process. We investigated the relationship between coding and five interventions recommended for CKD: achieving blood pressure targets, proteinuria testing, statin prescription and flu and pneumococcal vaccination. Of 256 000 patients with biochemical CKD, 30% did not have a GP CKD code. Males, older patients, those with more severe CKD, diabetes or hypertension or those prescribed statins were more likely to have a CKD code. Among those with continued biochemical CKD following audit, these same characteristics increased the odds of improved coding. Patients without any kidney diagnosis were less likely to receive optimal care than those coded for CKD [e.g. odds ratio for meeting blood pressure target 0.78 (95% confidence interval 0.76-0.79)]. Older age, male sex, diabetes and hypertension are associated with coding for those with biochemical CKD. CKD coding is associated with receiving key primary care interventions recommended for CKD. Increased efforts to incentivize CKD coding may improve outcomes for CKD patients. © The Author 2017. Published by Oxford University Press on behalf of ERA-EDTA.

    The aims of this study were to investigate the infectious etiology of primary chronic osteomyelitis (PCO) of the jaw using an extraoral sampling approach and molecular methods. In this pilot study, bone biopsies from the mandibles of 5 patients with PCO were sampled with an extraoral sterile approach. Cultivation and polymerase chain reaction (PCR) were performed. Two of the biopsies yielded growth of Propionebacterium acnes. One biopsy also demonstrated Staphylococcus capitis. The biopsies with bacterial growth were also positive for the same bacteria by PCR analysis. No specific bacterial etiology was demonstrated. However, the results of bacterial cultivation and PCR analysis were in agreement. Based on these findings, the molecular procedure used in this study can be considered to be suitable for identification of bacterial specimens in mandibular biopsies. Further studies are needed with larger patient populations to confirm these findings.

    Although transcranial direct current stimulation (tDCS) represents a therapeutic option for the prophylaxis of chronic migraine, the target area for application of the electrical current to the cortex has not yet been well established. Here we sought to determine whether a treatment protocol involving 12 sessions of 2mA, 20min anodal stimulation of the left primary motor (M1) or dorsolateral prefrontal cortex (DLPFC) could offer clinical benefits in the management of pain from migraine. Thirteen participants were assessed before and after treatment, using the Headache Impact Test-6, Visual Analogue Scale and Medical Outcomes Study 36 - Item Short - Form Health Survey. After treatment, group DLPFC exhibited a better performance compared with groups M1 and sham. On intragroup comparison, groups DLPFC and M1 exhibited a greater reduction in headache impact and pain intensity and a higher quality of life after treatment. No significant change was found in group sham. The participants in group M1 exhibited more adverse effects, especially headache, heartburn, and sleepiness, than did those in the other two groups. Transcranial direct current stimulation is a safe and efficacious technique for treating chronic migraine. However, it should be kept in mind that the site of cortical stimulation might modulate the patient's response to treatment. Copyright © 2017 Elsevier B.V. All rights reserved.

    Aims To describe symptoms and lung function in patients registered with asthma or chronic obstructive pulmonary disease (COPD) in primary care and to examine how spirometry findings fit with general practitioners’ (GPs) diagnoses. Methods Patients aged ≥40 years with a diagnosis of asthma or COPD registered in the electronic medical record during the previous 5 years were recruited at seven GP offices in Norway in 2009–2010. Registered diagnosis, spirometry results, comorbidity, and reported symptoms were compared. Results Among 376 patients, 62% were women. Based on Global Initiative for Chronic Obstructive Lung Diseases criteria, a spirometry diagnosis of COPD could be made in 68.1% of the patients with a previous COPD diagnosis and in 17.1% of those diagnosed with asthma only (P spirometry was 0.50. A restrictive spirometry pattern was found in 19.4% and more frequently in patients diagnosed with both asthma and COPD (23.9%) than in patients diagnosed with COPD only (6.8%, P = 0.003). Conclusion The ability of GPs to differentiate between asthma and COPD seems to have considerably improved during the last decade, probably due to the dissemination of spirometry and guidelines for COPD diagnosis. A diagnosis of COPD that cannot be confirmed by spirometry represents a challenge in clinical practice, in particular when a restrictive pattern on spirometry is found. PMID:22135492

    Mobile applications (apps) are promising tools to support chronic disease screening and linkage to health services. They have the potential to increase healthcare access for vulnerable populations. The HealthNavigator app was developed to provide chronic disease risk assessments, linkage to local general practitioners (GPs) and lifestyle programs, and a personalised health report for discussion with a GP. Assessments were either self-administered or facilitated by community health workers through a Primary Health Network (PHN) initiative targeting ethnically diverse communities. In total, 1492 assessments (80.4% self-administered, 19.6% facilitated) were conducted over a 12-month period in Queensland, Australia. Of these, 26% of people screened came from postcodes representing the lowest quartile of socioeconomic disadvantage. When compared against self-administered assessments, subjects screened by the facilitated program were more likely to be born outside Australia (80.5 v. 33.2%, P<0.001), and to fall within a high risk category based on cardiovascular risk scores (19.8 v. 13.7%, P<0.01) and type 2 diabetes mellitus risk scores (58.0 v. 40.1%, P<0.001). Mobile apps embedded into PHN programs may be a useful adjunct for the implementation of community screening programs. Further research is needed to determine their effect on health service access and health outcomes.

Patients and methods: Participants received either usual care or CCM by a team of health care professionals including pharmacists, nurses, dietitians, and general practitioners. The participants in the intervention group received medication counseling, adherence, and dietary advice from the health care team. The QoL was measured using the EQ-5D (EuroQoL-five dimension, health-related quality of life questionnaire and comparison was made between usual care and intervention groups at the beginning and end of the study at 6 months. Results: Mean (standard deviation EQ-5D index scores improved significantly in the intervention group (0.92±0.10 vs 0.95±0.08; P≤0.01, but not in the usual care group (0.94±0.09 vs 0.95±0.09; P=0.084. Similarly, more participants in the intervention group reported improvements in their QoL compared with the usual care group, especially in the pain/discomfort and anxiety/depression dimensions. Conclusion: The implementation of the CCM resulted in significant improvement in QoL. An interdisciplinary team CCM approach should be encouraged, to ultimately result in behavior changes and improve the QoL of the patients. Keywords: diabetes

    Madeleine Bennett

    Full Text Available This qualitative study explored the impact and appropriateness of structured pro-active care reviews by practice nurses for patients with chronic or recurrent depression and dysthymia within the ProCEED trial. ProCEED (Pro-active Care and its Evaluation for Enduring Depression was a United Kingdom wide randomised controlled trial, comparing usual general practitioner care with structured 'pro-active care' which involved 3 monthly review appointments with practice nurses over 2 years for patients with chronic or recurrent depression.In-depth interviews were completed with 41 participants: 26 patients receiving pro-active care and 15 practice nurses providing this care. Interview transcripts were analysed thematically using a 'framework' approach.Patients perceived the practice nurses to be appropriate professionals to engage with regarding their depression and most nurses felt confident in a case management role. The development of a therapeutic alliance between the patient and nurse was central to this model and, where it appeared lacking, dissatisfaction was felt by both patients and nurses with a likely negative impact on outcomes. Patient and nurse factors impacting on the therapeutic alliance were identified and nurse typologies explored.Pro-active care reviews utilising practice nurses as case managers were found acceptable by the majority of patients and practice nurses and may be a suitable way to provide care for patients with long-term depression in primary care. Motivated and interested practice nurses could be an appropriate and valuable resource for this patient group. This has implications for resource decisions by clinicians and commissioners within primary care.

    Full Text Available Background Health risk assessment tools compute an individual’s risk of developing a disease. Routine use of such tools by primary care physicians (PCPs is potentially useful in chronic disease prevention. We sought physicians’ awareness and perceptions of the usefulness, usability and feasibility of performing assessments with computer-based risk assessment tools in primary care settings.Methods Focus groups and usability testing with a computer-based risk assessment tool were conducted with PCPs from both university-affiliated and community-based practices. Analysis was derived from grounded theory methodology.Results PCPs (n = 30 were aware of several risk assessment tools although only select tools were used routinely. The decision to use a tool depended on how use impacted practice workflow and whether the tool had credibility. Participants felt that embedding tools in the electronic medical records (EMRs system might allow for health information from the medical record to auto-populate into the tool. User comprehension of risk could also be improved with computer-based interfaces that present risk in different formats.Conclusions In this study, PCPs chose to use certain tools more regularly because of usability and credibility. Despite there being differences in the particular tools a clinical practice used, there was general appreciation for the usefulness of tools for different clinical situations. Participants characterised particular features of an ideal tool, feeling strongly that embedding risk assessment tools in the EMR would maximise accessibility and use of the tool for chronic disease management. However, appropriate practice workflow integration and features that facilitate patient understanding at point-of-care are also essential.

    Asthma is a common disease with enormous public health costs, and its primary prevention is an ambitious and important goal. Understanding of how host and environmental factors interact to cause asthma is incomplete, but persistent questions about mechanisms should not stop clinical research efforts aimed at reducing the prevalence of childhood asthma. Achieving the goal of primary prevention of asthma will involve integrated and parallel sets of research activities in which mechanism-oriented studies of asthma inception proceed alongside clinical intervention studies to test biologically plausible prevention ideas. For example, continued research is needed, particularly in young children, to uncover biomarkers that identify asthma risk and provide potential targets of intervention, and to improve understanding of the role of microbial factors in asthma risk and disease initiation. In terms of clinical trials that could be initiated now or in the near future, we recommend three interventions for testing: (1) preventing asthma through prophylaxis against respiratory syncytial virus and human rhinovirus infections of the airway; (2) immune modulation, using prebiotics, probiotics, and bacterial lysates; and (3) prevention of allergen sensitization and allergic inflammation, using anti-IgE. These interventions should be tested while other, more universal prevention measures that may promote lung health are also investigated. These potential universal lung health measures include prevention of preterm delivery; reduced exposure of the fetus and young infant to environmental pollutants, including tobacco smoke; prevention of maternal and child obesity; and management of psychosocial stress.

    Full Text Available Chronic pain is a significant problem among military personnel and a priority of the military health system. The U.S. Army Surgeon General's Pain Management Task Force recommends using telehealth capabilities to enhance pain management. This article describes the development and evaluation of a telehealth intervention (TelePain designed to improve access to pain specialist consultation in the military health system. The study uses a wait-list cluster controlled clinical trial to test: 1 effectiveness of the intervention, and 2 interviews to assess barriers and facilitators of the intervention implementation. The intervention involves a didactic presentation based on the Joint Pain Education Curriculum followed by patient case presentations and multi-disciplinary discussion via videoconference by clinicians working in the military health system. A panel of pain specialists representing pain medicine, internal medicine, anesthesiology, rehabilitation medicine, psychiatry, addiction medicine, health psychology, pharmacology, nursing, and complementary and integrative pain management provide pain management recommendations for each patient case. We use the Pain Assessment Screening Tool and Outcomes Registry (PASTOR to measure patient outcomes, including pain, sleep, fatigue, anxiety, and depression. This article reports some of the challenges and lessons learned during early implementation of the TelePain intervention. Weekly telephone meetings among the multisite research team were instrumental in problem solving, identifying problem areas, and developing solutions. Solutions for recruitment challenges included additional outreach and networking to military health providers, both building on existing relationships and new relationships.

    Chronic pain is a significant problem among military personnel and a priority of the military health system. The U.S. Army Surgeon General's Pain Management Task Force recommends using telehealth capabilities to enhance pain management. This article describes the development and evaluation of a telehealth intervention (TelePain) designed to improve access to pain specialist consultation in the military health system. The study uses a wait-list controlled clinical trial to test: 1) effectiveness of the intervention, and 2) interviews to assess barriers and facilitators of the intervention implementation. The intervention involves a didactic presentation based on the Joint Pain Education Curriculum followed by patient case presentations and multi-disciplinary discussion via videoconference by clinicians working in the military health system. A panel of pain specialists representing pain medicine, internal medicine, anesthesiology, rehabilitation medicine, psychiatry, addiction medicine, health psychology, pharmacology, nursing, and complementary and integrative pain management provide pain management recommendations for each patient case. We use the Pain Assessment Screening Tool and Outcomes Registry (PASTOR) to measure patient outcomes, including pain, sleep, fatigue, anxiety, and depression. This article reports some of the challenges and lessons learned during early implementation of the TelePain intervention. Weekly telephone meetings among the multisite research team were instrumental in problem solving, identifying problem areas, and developing solutions. Solutions for recruitment challenges included additional outreach and networking to military health providers, both building on.

    Full Text Available Abstract Background Although in developing countries the burden of morbidity and mortality due to infectious diseases has often overshadowed that due to chronic non-communicable diseases (NCDs, there is evidence now of a shift of attention to NCDs. Discussion Decreasing the chronic NCD burden requires a two-pronged approach: implementation of the multisectoral policies aimed at decreasing population-level risks for NCDs, and effective and affordable delivery of primary care interventions for patients with chronic NCDs. The primary care response to common NCDs is often unstructured and inadequate. We therefore propose a programmatic, standardized approach to the delivery of primary care interventions for patients with NCDs, with a focus on hypertension, diabetes mellitus, chronic airflow obstruction, and obesity. The benefits of this approach will extend to patients with related conditions, e.g. those with chronic kidney disease caused by hypertension or diabetes. This framework for a "public health approach" is informed by experience of scaling up interventions for chronic infectious diseases (tuberculosis and HIV. The lessons learned from progress in rolling out these interventions include the importance of gaining political commitment, developing a robust strategy, delivering standardised interventions, and ensuring rigorous monitoring and evaluation of progress towards defined targets. The goal of the framework is to reduce the burden of morbidity, disability and premature mortality related to NCDs through a primary care strategy which has three elements: 1 identify and address modifiable risk factors, 2 screen for common NCDs and 3 and diagnose, treat and follow-up patients with common NCDs using standard protocols. The proposed framework for NCDs borrows the same elements as those developed for tuberculosis control, comprising a goal, strategy and targets for NCD control, a package of interventions for quality care, key operations for

    Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is a complex condition. Causal factors are not established, although underlying psychological or immunological susceptibility has been proposed. We studied primary care diagnoses for children with CFS/ME, with children with another hospital diagnosis (type 1 diabetes mellitus [T1DM]) and the general child population as comparison groups. All Norwegian children born 1992-2012 constituted the study sample. Children with CFS/ME (n = 1670) or T1DM (n = 4937) were identified in the Norwegian Patient Register (NPR) (2008-2014). Children without either diagnosis constituted the general child population comparison group (n = 1337508). We obtained information on primary care diagnoses from the Norwegian Directorate of Health. For each primary care diagnosis, the proportion and 99 % confidence interval (CI) within the three groups was calculated, adjusted for sex and age by direct standardization. Children with CFS/ME were more often registered with a primary care diagnosis of weakness/general tiredness (89.9 % [99 % CI 88.0 to 91.8 %]) than children in either comparison group (T1DM: 14.5 % [99 % CI: 13.1 to 16.0 %], general child population: 11.1 % [99 % CI: 11.0 to 11.2 %]). Also, depressive disorder and anxiety disorder were more common in the CFS/ME group, as were migraine, muscle pain, and infections. In the 2 year period prior to the diagnoses, infectious mononucleosis was registered for 11.1 % (99 % CI 9.1 to 13.1 %) of children with CFS/ME and for 0.5 % (99 % CI (0.2 to 0.8 %) of children with T1DM. Of children with CFS/ME, 74.6 % (1292/1670) were registered with a prior primary care diagnosis of weakness / general tiredness. The time span from the first primary care diagnosis of weakness / general tiredness to the specialist health care diagnosis of CFS/ME was 1 year or longer for 47.8 %. This large nationwide registry linkage study confirms that the clinical picture in CFS

    Full Text Available INTRODUCTION: Many risk factors have been identified for chronic low back pain (cLBP, but only one study evaluated their interrelations. We aimed to investigate the frequency of cLBP risk factors and their interrelations in patients consulting their general practitioners (GPs for cLBP. METHODS: A cross-sectional, descriptive, national survey was performed. 3000 GPs randomly selected were asked to include at least one patient consulting for cLBP. Demographic, clinical characteristics and the presence of cLBP risk factors were recorded. The frequency of each cLBP risk factor was calculated and multiple correspondence analysis (MCA was performed to study their interrelations. RESULTS: A total of 2068 GPs (68.9% included at least 1 patient, for 4522 questionnaires analyzed. In the whole sample of patients, the 2 risk factors most commonly observed were history of recurrent LBP (72.1% and initial limitation of activities of daily living (66.4%. For working patients, common professional risk factors were beliefs, that LBP was due to maintaining a specific posture at work (79.0% and frequent heavy lifting at work (65.5%. On MCA, we identified 3 risk-factor dimensions (axes for working and nonworking patients. The main dimension for working patients involved professional risk factors and among these factors, patients' job satisfaction and job recognition largely contribute to this dimension. DISCUSSION: Our results shed in light for the first time the interrelation and the respective contribution of several previously identified cLBP risk factors. They suggest that risk factors representing a "work-related" dimension are the most important cLBP risk factors in the working population.

    Sleep disturbance, pain, anxiety, depression, and low energy/fatigue, the SPADE pentad, are the most prevalent and co-occurring symptoms in the general population and clinical practice. Co-occurrence of SPADE symptoms may produce additive impairment and negatively affect treatment response, potentially undermining patients' health and functioning. The purpose of this paper is to determine: (1) prevalence and comorbidity (ie, clustering) of SPADE symptoms; (2) internal reliability and construct validity of a composite SPADE symptom score derived from the Patient-Reported Outcomes Measurement Information System (PROMIS) measures; and (3) whether improvement in somatic symptom burden represented by a composite score predicted subsequent measures of functional status at 3 and 12 months follow-up. Secondary analysis of data from the Stepped Care to Optimize Pain care Effectiveness study, a randomized trial of a collaborative care intervention for Veterans with chronic pain. Most patients had multiple SPADE symptoms; only 9.6% of patients were monosymptomatic. The composite PROMIS symptom score had good internal reliability (Cronbach's alpha=0.86) and construct validity and strongly correlated with multiple measures of functional status; improvement in the composite score significantly correlated with higher scores for 5 of 6 functional status outcomes. The standardized error of measurement (SEM) for the composite T-score was 2.84, suggesting a 3-point difference in an individual's composite score may be clinically meaningful. Brief PROMIS measures may be useful in evaluating SPADE symptoms and overall symptom burden. Because symptom burden may predict functional status outcomes, better identification and management of comorbid symptoms may be warranted.

    Following independence from the Soviet Union in 1991, Estonia introduced a national insurance system, consolidated the number of health care providers, and introduced family medicine centred primary health care (PHC) to strengthen the health system. Using routinely collected health billing records for 2005-2012, we examine health system utilisation for seven ambulatory care sensitive conditions (ACSCs) (asthma, chronic obstructive pulmonary disease [COPD], depression, Type 2 diabetes, heart failure, hypertension, and ischemic heart disease [IHD]), and by patient characteristics (gender, age, and number of co-morbidities). The data set contained 552 822 individuals. We use patient level data to test the significance of trends, and employ multivariate regression analysis to evaluate the probability of inpatient admission while controlling for patient characteristics, health system supply-side variables, and PHC use. Over the study period, utilisation of PHC increased, whilst inpatient admissions fell. Service mix in PHC changed with increases in phone, email, nurse, and follow-up (vs initial) consultations. Healthcare utilisation for diabetes, depression, IHD and hypertension shifted to PHC, whilst for COPD, heart failure and asthma utilisation in outpatient and inpatient settings increased. Multivariate regression indicates higher probability of inpatient admission for males, older patient and especially those with multimorbidity, but protective effect for PHC, with significantly lower hospital admission for those utilising PHC services. Our findings suggest health system reforms in Estonia have influenced the shift of ACSCs from secondary to primary care, with PHC having a protective effect in reducing hospital admissions.

    Accurately identifying cases of chronic kidney disease (CKD) from primary care data facilitates the management of patients, and is vital for surveillance and research purposes. Ontologies provide a systematic and transparent basis for clinical case definition and can be used to identify clinical codes relevant to all aspects of CKD care and its diagnosis. We used routinely collected primary care data from the Royal College of General Practitioners Research and Surveillance Centre. A domain ontology was created and presented in Ontology Web Language (OWL). The identification and staging of CKD was then carried out using two parallel approaches: (1) clinical coding consistent with a diagnosis of CKD; (2) laboratory-confirmed CKD, based on estimated glomerular filtration rate (eGFR) or the presence of proteinuria. The study cohort comprised of 1.2 million individuals aged 18 years and over. 78,153 (6.4%) of the population had CKD on the basis of an eGFR of < 60 mL/min/1.73m 2 , and a further 7366 (0.6%) individuals were identified as having CKD due to proteinuria. 19,504 (1.6%) individuals without laboratory-confirmed CKD had a clinical code consistent with the diagnosis. In addition, a subset of codes allowed for 1348 (0.1%) individuals receiving renal replacement therapy to be identified. Finding cases of CKD from primary care data using an ontological approach may have greater sensitivity than less comprehensive methods, particularly for identifying those receiving renal replacement therapy or with CKD stages 1 or 2. However, the possibility of inaccurate coding may limit the specificity of this method.

    The use of computerized clinical decision support systems may improve the diagnosis and ongoing management of chronic diseases, which requires recurrent visits to multiple health professionals, disease and medication monitoring and modification of patient behavior. The aim of this review was to systematically review randomized controlled trials evaluating the effectiveness of computerized clinical decision systems (CCDSS) in the care of people with asthma and COPD. Randomized controlled trials published between 2003 and 2013 were searched using multiple electronic databases Medline, EMBASE, CINAHL, IPA, Informit, PsychINFO, Compendex, and Cochrane Clinical Controlled Trials Register databases. To be included, RCTs had to evaluate the role of the CCDSSs for asthma and/or COPD in primary care. Nineteen studies representing 16 RCTs met our inclusion criteria. The majority of the trials were conducted in patients with asthma. Study quality was generally high. Meta-analysis was not conducted because of methodological and clinical heterogeneity. The use of CCDSS improved asthma and COPD care in 14 of the 19 studies reviewed (74%). Nine of the nineteen studies showed statistically significant (p < 0.05) improvement in the primary outcomes measured. The majority of the studies evaluated health care process measures as their primary outcomes (10/19). Evidence supports the effectiveness of CCDSS in the care of people with asthma. However there is very little information of its use in COPD care. Although there is considerable improvement in the health care process measures and clinical outcomes through the use of CCDSSs, its effects on user workload and efficiency, safety, costs of care, provider and patient satisfaction remain understudied.

    This study is a process evaluation of the Quality Improvement in Chronic Kidney Disease (QICKD) study, comparing audit-based education (ABE) and sending clinical guidelines and prompts (G&P) with usual practice, in improving systolic blood pressure control in primary care. This evaluation aimed to explore how far clinical staff in participating practices were aware of the intervention, and why change in practice might have taken place. 4 primary care practices in England: 2 received ABE, and 2 G&P. We purposively selected 1 northern/southern/city and rural practice from each study arm (from a larger pool of 132 practices as part of the QICKD trial). The 4 study practices were purposively sampled, and focus groups conducted with staff from each. All staff members were invited to attend. Focus groups in each of 4 practices, at the mid-study point and at the end. 4 additional trial practices not originally selected for in-depth process evaluation took part in end of trial focus groups, to a total of 12 focus groups. These were recorded, transcribed and analysed using the framework approach. 5 themes emerged: (1) involvement in the study made participants more positive about the CKD register; (2) clinicians did not always explain to patients that they had CKD; (3) while practitioners improved their monitoring of CKD, many were sceptical that it improved care and were more motivated by pay-for-performance measures; (4) the impact of study interventions on practice was generally positive, particularly the interaction with specialists, included in ABE; (5) the study stimulated ideas for future clinical practice. Improving quality in CKD is complex. Lack of awareness of clinical guidelines and scepticism about their validity are barriers to change. While pay-for-performance incentives are the main driver for change, quality improvement interventions can have a complementary influence. Published by the BMJ Publishing Group Limited.

    Methods. Analyzed the results of surgical treatment of 132 patients, including 68 - for cancer of the pancreatic head (in 46 - with jaundice and 64 - chronic pancreatitis (CP with a primary lesion of the pancreatic head (16 - with jaundice. The distribution of patients into groups was carried out with a maximum value of classification functions calculated by special formulas. Next studied indicators of endothelial dysfunction for differential diagnosis.  Results. It was defined the threshold of VEGF = 346 pg/ml, which shared the group of chronic pancreatitis or cancer of the pancreatic head, which was determined based on the Pareto criterion. This model sensitivity was 72.1% and specificity of 75% for the overall accuracy of 72.7%. Even more precision indicator was on the threshold of VEGF = 248 pg/ml, which compared groups of patients with cancer and software of the control group (125.9 pg/ml and the sensitivity was 86.8%, specificity 82.4%, and overall accuracy of 82.3%. At about the same accuracy had this test and the comparison group of patients with chronic pancreatitis and control: sensitivity 84.4% and specificity of 76.5% overall accuracy of 81.5% in the threshold VEGF of 155 pg/ml (p<0,05. To develop a prognosis of a pathological process, along with the use of diagnostic data used a method of classification trees. The model showed that the index VEGF is the criterion that discriminates for pancreas- pancreatic cancer-pancreas, but relative differences in the presence of jaundice in patients defined using S-nitrozothiol. The accuracy of the proposed method of prediction was 89%, the price of cross-checking - 82,6% (p<0,05.

    Utilizing psychological resources when dealing with chronic low back pain might aid the prevention of disability. The observational study at hand examined the longitudinal impact of resilience and coping resources on disability in addition to established risk factors. Four hundred eighty four patients with chronic low back pain (>3 months) were recruited in primary care practices and followed up for one year. Resilience, coping, depression, somatization, pain and demographic variables were measured at baseline. At follow-up (participation rate 89%), data on disability was collected. We first calculated bivariate correlations of all the predictors with each other and with follow-up disability. We then used a multiple regression to evaluate the impact of all the predictors on disability together. More than half of the followed up sample showed a high degree of disability at baseline (53.7%) and had suffered for more than 10 years from pain (50.4%). Besides gender all of the predictors were bivariately associated with follow-up disability. However in the main analysis (multiple regression), disability at follow up was only predicted by baseline disability, age and somatization. There was no relationship between resilience and disability, nor between coping resources and disability. Although it is known that there are cross-sectional relationships between resilience/coping resources and disability we were not able to replicate it in the multiple regression. This can have several reasons: a) the majority of patients in our sample were much more disabled and suffered for a longer time than in other studies. Therefore our results might be limited to this specific population and resilience and coping resources might still have a protective influence in acute or subacute populations. b) We used a rather broad operationalization of resilience. There is emerging evidence that focusing on more concrete sub facets like (pain) self-efficacy and acceptance might be more

    Indigenous residents living in remote communities in Australia's Northern Territory experience higher rates of preventable chronic disease and have poorer access to appropriate health services compared to other Australians. This study compared health outcomes and costs at different levels of primary care utilisation to determine if primary care represents an efficient use of resources for Indigenous patients with common chronic diseases namely hypertension, diabetes, ischaemic heart disease, chronic obstructive pulmonary disease and renal disease. This was an historical cohort study involving a total of 14,184 Indigenous residents, aged 15 years and over, who lived in remote communities and used a remote clinic or public hospital from 2002 to 2011. Individual level demographic and clinical data were drawn from primary care and hospital care information systems using a unique patient identifier. A propensity score was used to improve comparability between high, medium and low primary care utilisation groups. Incremental cost-effectiveness ratios and acceptability curves were used to analyse four health outcome measures: total and, avoidable hospital admissions, deaths and years of life lost. Compared to the low utilisation group, medium and high levels of primary care utilisation were associated with decreases in total and avoidable hospitalisations, deaths and years of life lost. Higher levels of primary care utilisation for renal disease reduced avoidable hospitalisations by 82-85%, deaths 72-75%, and years of life lost 78-81%. For patients with ischaemic heart disease, the reduction in avoidable hospitalisations was 63-78%, deaths 63-66% and years of life lost 69-73%. In terms of cost-effectiveness, primary care for renal disease and diabetes ranked as more cost-effective, followed by hypertension and ischaemic heart disease. Primary care for chronic obstructive pulmonary disease was the least cost-effective of the five conditions. Primary care in remote

    In response to the increasing demand for better chronic disease management and improved health care efficiency in Ontario, nursing roles have expanded in the primary health care setting. To determine the effectiveness of specialized nurses who have a clinical role in patient care in optimizing chronic disease management among adults in the primary health care setting. A literature search was performed using OVID MEDLINE, OVID MEDLINE In-Process and Other Non-Indexed Citations, OVID EMBASE, EBSCO Cumulative Index to Nursing & Allied Health Literature (CINAHL), the Wiley Cochrane Library, and the Centre for Reviews and Dissemination database. Results were limited to randomized controlled trials and systematic reviews and were divided into 2 models: Model 1 (nurse alone versus physician alone) and Model 2 (nurse and physician versus physician alone). Effectiveness was determined by comparable outcomes between groups in Model 1, or improved outcomes or efficiency in Model 2. Six studies were included. In Model 1, there were no significant differences in health resource use, disease-specific measures, quality of life, or patient satisfaction. In Model 2, there was a reduction in hospitalizations and improved management of blood pressure and lipids among patients with coronary artery disease. Among patients with diabetes, there was a reduction in hemoglobin A1c but no difference in other disease-specific measures. There was a trend toward improved process measures, including medication prescribing and clinical assessments. Results related to quality of life were inconsistent, but patient satisfaction with the nurse-physician team was improved. Overall, there were more and longer visits to the nurse, and physician workload did not change. There was heterogeneity across patient populations, and in the titles, roles, and scope of practice of the specialized nurses. Specialized nurses with an autonomous role in patient care had comparable outcomes to physicians alone (Model

    Undiagnosed chronic kidney disease (CKD) contributes to a high cost and care burden in secondary care. Uptake of evidence-based guidelines in primary care is inconsistent, resulting in variation in the detection and management of CKD. Routinely collected general practice data in one UK region suggested a CKD prevalence of 4.1%, compared with an estimated national prevalence of 8.5%. Of patients on CKD registers, ∼ 30% were estimated to have suboptimal management according to Public Health Observatory analyses. An evidence-based framework for implementation was developed. This informed the design of an improvement collaborative to work with a sample of 30 general practices. A two-phase collaborative was implemented between September 2009 and March 2012. Key elements of the intervention included learning events, improvement targets, Plan-Do-Study-Act cycles, benchmarking of audit data, facilitator support and staff time reimbursement. Outcomes were evaluated against two indicators: number of patients with CKD on practice registers; percentage of patients achieving evidence-based blood pressure (BP) targets, as a marker for CKD care. In Phase 1, recorded prevalence of CKD in collaborative practices increased ∼ 2-fold more than that in comparator local practices; in Phase 2, this increased to 4-fold, indicating improved case identification. Management of BP according to guideline recommendations also improved. An improvement collaborative with tailored facilitation support appears to promote the uptake of evidence-based guidance on the identification and management of CKD in primary care. A controlled evaluation study is needed to rigorously evaluate the impact of this promising improvement intervention. © The Author 2014.

    Injection drug users are at high risk for chronic hepatitis C virus infection (CHC). Opioid maintenance treatment (OMT) offers a unique opportunity to screen for CHC. This study proposed the hypothesis that a general practitioner (GP) with special interest in addiction medicine can achieve CHC screening rates comparable to specialized centres and aimed to investigate determinants for a successful CHC case finding in a primary care setting. Retrospective medical record analysis of 387 patients who received opioid maintenance therapy between 1 January 2002 and 31 May 2008 in a general practice in Zurich, Switzerland. Successful CHC assessment was defined as performance of hepatitis C virus (HCV) serology with consecutive polymerase chain reaction-based RNA and genotype recordings. The association between screening success and patient characteristics was assessed using multiple logistic regression. findings: Median (interquartile range) age and duration of OMT of the 387 (268 males) patients was 38.5 (33.6-44.5) years and 34 (11.3-68.0) months, respectively. Fourteen patients (3.6%) denied HCV testing and informed consent about screening was missing in 13 patients (3.4%). In 327 of 360 patients (90.8%) with informed consent a successful CHC assessment has been performed. Screening for HCV antibodies was positive in 136 cases (41.6%) and in 86 of them (63.2%) a CHC was present. The duration of OMT was an independent determinant of a successful CHC assessment. In addicted patients a high CHC assessment rate in a primary care setting in Switzerland is feasible and opioid substitution provides an optimal framework.

    The probability that ionizing radiation induces a t(9;22) reciprocal translocation with its break points confined to the same regions as the break points for the Philadelphia (Ph') translocation in chronic myelogenous leukemia (CML) has been calculated to be 7 x 10[sup -12] per cell and gray. This figure was used to estimate the number of individuals among the atomic bomb survivors at Hiroshima and Nagasaki with such an induced translocation. For 9196 atomic bomb survivors who received a mean organ dose equivalent to bone marrow of 0.85 sievert, the estimate is done that the number of individuals with a radiation-induced t(9;22) translocation in one of the pluripotent stem cells in bone marrow is of the order of 50. The observed number of affected individuals with CML within the same cohort is 18. Even if the estimate of the number of individuals has relatively large errors, this indicates that the primary event in the radiation-induced CML cases can be a radiation-induced t(9;22) reciprocal translocation.

    Background Individuals with mental illness experience poor health and may die prematurely from chronic illness. Understanding whether the presence of co-occurring chronic physical health conditions complicates mental health treatment is important, particularly among patients seeking treatment in primary care settings. Objectives Examine (1) whether the presence of chronic physical conditions is associated with mental health service use for individuals with depression who visit a primary care physician, and (2) whether race modifies this relationship. Research Design Secondary analysis of the National Ambulatory Medical Care Survey, a survey of patient-visits collected annually from a random sample of 3,000 physicians in office-based settings. Subjects Office visits from 2007–2010 were pooled for adults ages 35–85 with a depression diagnosis at the time of visit (N=3,659 visits). Measures Mental health services were measured using a dichotomous variable indicating whether mental health services were provided during the office visit or a referral made for: (1) counseling, including psychotherapy and other mental health counseling and/or (2) prescribing of psychotropic medications. Results Most patient office visits (70%) where a depression diagnosis was recorded also had co-occurring chronic physical conditions recorded. The presence of at least one physical chronic condition was associated with a 6% decrease in the probability of receiving any mental health services (pneeded on medical care delivery among patients with co-occurring health conditions, particularly as the health care system moves towards an integrated care model.

    To examine the use of individual care plans (ICPs) within primary chronic illness care in the Netherlands, and to explore the relationships between ICP use, patient characteristics, and patient-perceived quality of care. Cross-sectional study using survey data from a panel of chronically ill patients and medical registration data provided by their general practices. A sample of 1377 patients with somatic chronic disease(s) randomly selected in general practices throughout the Netherlands, supplemented with a sample of 225 COPD patients, also recruited from general practices. (i) Percentage of ICP use based on self-report by chronically ill patients, and (ii) patient-perceived quality of care as assessed using the Patient Assessment of Chronic Illness Care (PACIC). ICP use among the total generic sample was low (9%), but slightly higher (13%) among patients diagnosed with diabetes or COPD, diseases for which disease management programmes have been set up in the Netherlands. Patients with a low educational level and patients with poor(er) self-rated health were more likely to have an ICP. Compared with patients without an ICP, patients with an ICP more often reported that the care they received was patient-centred, proactive, planned, and included collaborative goal setting, problem-solving, and follow-up support. Findings reveal a discrepancy between practice and policy aspirations regarding ICP use in primary chronic illness care. More research is needed to gain insight into the effectiveness of ICPs to improve the quality of chronic illness care in various patient populations.

    To explore differences in mean costs (from a UK National Health Service perspective) and effects of pharmacist-led management of chronic pain in primary care evaluated in a pilot randomised controlled trial (RCT), and to estimate optimal sample size for a definitive RCT. Regression analysis of costs and effects, using intention-to-treat and expected value of sample information analysis (EVSI). Six general practices: Grampian (3); East Anglia (3). 125 patients with complete resource use and short form-six-dimension questionnaire (SF-6D) data at baseline, 3 months and 6 months. Patients were randomised to either pharmacist medication review with face-to-face pharmacist prescribing or pharmacist medication review with feedback to general practitioner or treatment as usual (TAU). Differences in mean total costs and effects measured as quality-adjusted life years (QALYs) at 6 months and EVSI for sample size calculation. Unadjusted total mean costs per patient were £452 for prescribing (SD: £466), £570 for review (SD: £527) and £668 for TAU (SD: £1333). After controlling for baseline costs, the adjusted mean cost differences per patient relative to TAU were £77 for prescribing (95% CI -82 to 237) and £54 for review (95% CI -103 to 212). Unadjusted mean QALYs were 0.3213 for prescribing (SD: 0.0659), 0.3161 for review (SD: 0.0684) and 0.3079 for TAU (SD: 0.0606). Relative to TAU, the adjusted mean differences were 0.0069 for prescribing (95% CI -0.0091 to 0.0229) and 0.0097 for review (95% CI -0.0054 to 0.0248). The EVSI suggested the optimal future trial size was between 460 and 690, and between 540 and 780 patients per arm using a threshold of £30,000 and £20,000 per QALY gained, respectively. Compared with TAU, pharmacist-led interventions for chronic pain appear more costly and provide similar QALYs. However, these estimates are imprecise due to the small size of the pilot trial. The EVSI indicates that a larger trial is necessary to obtain more

    Emergency admission risk prediction models are increasingly used to identify patients, typically with one or more chronic conditions, for proactive management in primary care to avoid admissions, save costs and improve patient experience. To identify and review the published evidence on the costs, effects and implementation of emergency admission risk prediction models in primary care for patients with, or at risk of, chronic conditions. We shall search for studies of healthcare interventions using routine data-generated emergency admission risk models. We shall report: the effects on emergency admissions and health costs; clinician and patient views; and implementation findings. We shall search ASSIA, CINAHL, the Cochrane Library, HMIC, ISI Web of Science, MEDLINE and Scopus from 2005, review references in and citations of included articles, search key journals and contact experts. Study selection, data extraction and quality assessment will be performed by two independent reviewers. No ethical permissions are required for this study using published data. Findings will be disseminated widely, including publication in a peer-reviewed journal and through conferences in primary and emergency care and chronic conditions. We judge our results will help a wide audience including primary care practitioners and commissioners, and policymakers. CRD42015016874; Pre-results. Published by the BMJ Publishing Group Limited.

    Purpose The purpose of this paper is to reduce inappropriate non-steroidal anti-inflammatory prescribing in primary care patients with chronic kidney disease (CKD). Once diagnosed, CKD management involves delaying progression to end stage renal failure and preventing complications. It is well established that non-steroidal anti-inflammatories have a negative effect on kidney function and consequently, all nephrology consensus groups suggest avoiding this drug class in CKD. Design/methodology/approach The sampling criteria included all practice patients with a known CKD risk factor. This group was refined to include those with an estimated glomerular filtration rate (eGFR)<60 ml/min per 1.73m2 (stage 3 CKD or greater). Phase one analysed how many prescriptions had occurred in this group over the preceding three months. The intervention involved creating an automated alert on at risk patient records if non-steroidal anti-inflammatories were prescribed and discussing the rationale with practice staff. The re-audit phase occurred three months' post intervention. Findings The study revealed 728/7,500 (9.7 per cent) patients at risk from CKD and 158 (2.1 per cent) who were subsequently found to have an eGFR<60 ml/min, indicating=stage 3 CKD. In phase one, 10.2 per cent of at risk patients had received a non-steroidal anti-inflammatory prescription in the preceding three months. Additionally, 6.2 per cent had received non-steroidal anti-inflammatories on repeat prescription. Phase two post intervention revealed a significant 75 per cent reduction in the total non-steroidal anti-inflammatories prescribed and a 90 per cent reduction in repeat non-steroidal anti-inflammatory prescriptions in those with CKD. Originality/value The study significantly reduced non-steroidal anti-inflammatory prescription in those with CKD in primary care settings. It also created a CKD register within the practice and an enduring medication alert system for individuals that risk nephrotoxic

    Fatigue is prevalent and disabling in primary Sjögren's syndrome (pSS). Results from studies in chronic fatigue syndrome (CFS) indicate that genetic variation may influence fatigue. The aim of this study was to investigate single nucleotide polymorphism (SNP) variations in pSS patients with high and low fatigue. A panel of 85 SNPs in 12 genes was selected based on previous studies in CFS. A total of 207 pSS patients and 376 healthy controls were genotyped. One-hundred and ninety-three patients and 70 SNPs in 11 genes were available for analysis after quality control. Patients were dichotomized based on fatigue visual analogue scale (VAS) scores, with VAS fatigue" (n = 53) and VAS ≥50 denominated "high fatigue" (n = 140). We detected signals of association with pSS for one SNP in SLC25A40 (unadjusted p = 0.007) and two SNPs in PKN1 (both p = 0.03) in our pSS case versus control analysis. The association with SLC25A40 was stronger when only pSS high fatigue patients were analysed versus controls (p = 0.002). One SNP in PKN1 displayed an association in the case-only analysis of pSS high fatigue versus pSS low fatigue (p = 0.005). This candidate gene study in pSS did reveal a trend for associations between genetic variation in candidate genes and fatigue. The results will need to be replicated. More research on genetic associations with fatigue is warranted, and future trials should include larger cohorts and multicentre collaborations with sharing of genetic material to increase the statistical power.

    Most chronic diseases are managed in primary and ambulatory care. The chronic care model (CCM) suggests a wide range of community, technological, team and patient factors contribute to effective chronic disease management. Ontologies have the capability to enable formalised linkage of heterogeneous data sources as might be found across the elements of the CCM. To describe the evidence base for using ontologies and other semantic integration methods to support chronic disease management. We reviewed the evidence-base for the use of ontologies and other semantic integration methods within and across the elements of the CCM. We report them using a realist review describing the context in which the mechanism was applied, and any outcome measures. Most evidence was descriptive with an almost complete absence of empirical research and important gaps in the evidence-base. We found some use of ontologies and semantic integration methods for community support of the medical home and for care in the community. Ubiquitous information technology (IT) and other IT tools were deployed to support self-management support, use of shared registries, health behavioural models and knowledge discovery tools to improve delivery system design. Data quality issues restricted the use of clinical data; however there was an increased use of interoperable data and health system integration. Ontologies and semantic integration methods are emergent with limited evidence-base for their implementation. However, they have the potential to integrate the disparate community wide data sources to provide the information necessary for effective chronic disease management.

    The aim of this study was to identify the challenges faced by primary care physicians (PCPs) when prescribing medications for patients with chronic diseases in a teaching hospital in Malaysia. 3 focus group discussions were conducted between July and August 2012 in a teaching primary care clinic in Malaysia. A topic guide was used to facilitate the discussions which were audio-recorded, transcribed verbatim and analysed using a thematic approach. PCPs affiliated to the primary care clinic were purposively sampled to include a range of clinical experience. Sample size was determined by thematic saturation of the data. 14 family medicine trainees and 5 service medical officers participated in this study. PCPs faced difficulties in prescribing for patients with chronic diseases due to a lack of communication among different healthcare providers. Medication changes made by hospital specialists, for example, were often not communicated to the PCPs leading to drug duplications and interactions. The use of paper-based medical records and electronic prescribing created a dual record system for patients' medications and became a problem when the 2 records did not tally. Patients sometimes visited different doctors and pharmacies for their medications and this resulted in the lack of continuity of care. PCPs also faced difficulties in addressing patients' concerns, and dealing with patients' medication requests and adherence issues. Some PCPs lacked time and knowledge to advise patients about their medications and faced difficulties in managing side effects caused by the patients' complex medication regimen. PCPs faced prescribing challenges related to patients, their own practice and the local health system when prescribing for patients with chronic diseases. These challenges must be addressed in order to improve chronic disease management in primary care and, more importantly, patient safety. Published by the BMJ Publishing Group Limited.

    Chronic pain is highly prevalent in older adults, contributes to activity restriction and social isolation, disrupts family and interpersonal relationships, and poses a significant economic burden to society. Negative emotions such as sadness, anxiety, helplessness, and hopelessness are associated with chronic pain and contribute to poor quality of life, impaired interpersonal and social functioning, and increased disability. Psychosocial interventions for older adults with chronic pain have been historically developed for, and are almost exclusively delivered to, cognitively intact patients. Therefore, many older adults with chronic pain and comorbid cognitive deficits have limited treatment options. Our multidisciplinary team developed Problem Adaptation Therapy for Pain in Primary Care (PATH-Pain), a psychosocial intervention for older adults with chronic pain, negative emotions, and a wide range of cognitive functioning, including mild-to-moderate cognitive impairment. In the current article, we describe the principles underlying PATH-Pain, review the steps taken to adapt the original PATH protocol, outline the treatment process, and present a case illustrating its potential value.

    There are high growing prevalence rates of hypertension in South Africa. Consequently, there is a need to assess knowledge and management among hypertensive patients receiving chronic medication from primary health care (PHC) facilities in South Africa as a basis for improving future management. This is important as South Africa seeks to improve its management of chronic diseases. Descriptive, quantitative study amongst chronic hypertensive patients in the chronic disease programme. Patients were interviewed face-to-face by trained pharmacists using a structured questionnaire. Data analysis included descriptive and inferential statistics. Half (53.7%) of the patients had uncontrolled blood pressure (BP). Less than a third of patients (27.7%) knew what hypertension is, the meaning of recorded BP numbers (4.5%), and what normal BP should be (19.9%). All patients who knew the meaning of BP numbers had formal education (p = 0.047). Only 15.6% of the 56.0% patients, who received hypertension information, received it on antihypertensive medicines specifically. The majority of the patients lacked hypertension specific knowledge and only half had controlled BP. Interventions to improve the control of high BP should be targeted at closing knowledge gaps as part of the current chronic treatment initiatives in South Africa to ensure the benefits of increased access to care are realized.

    Full Text Available Abstract Background Multiple physiologic impairments are responsible for chronic wounds. A cell line grown which retains its phenotype from patient wounds would provide means of testing new therapies. Clinical information on patients from whom cells were grown can provide insights into mechanisms of specific disease such as diabetes or biological processes such as aging. The objective of this study was 1 To culture human cells derived from patients with chronic wounds and to test the effects of putative therapies, Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF on these cells. 2 To describe a methodology to create fibroblast cell lines from patients with chronic wounds. Methods Patient biopsies were obtained from 3 distinct locations on venous ulcers. Fibroblasts derived from different wound locations were tested for their migration capacities without stimulators and in response to GM-CSF. Another portion of the patient biopsy was used to develop primary fibroblast cultures after rigorous passage and antimicrobial testing. Results Fibroblasts from the non-healing edge had almost no migration capacity, wound base fibroblasts were intermediate, and fibroblasts derived from the healing edge had a capacity to migrate similar to healthy, normal, primary dermal fibroblasts. Non-healing edge fibroblasts did not respond to GM-CSF. Six fibroblast cell lines are currently available at the National Institute on Aging (NIA Cell Repository. Conclusion We conclude that primary cells from chronic ulcers can be established in culture and that they maintain their in vivo phenotype. These cells can be utilized for evaluating the effects of wound healing stimulators in vitro.

    The conceptual model of attachment theory has been applied to understand the predispositions of patients in medical care and the patient-provider relationship. In patients with chronic conditions insecure attachment was connected to poorer self-management. The patient-provider relationship is associated with a range of health related outcomes and self-management skills. We determined whether the quality of the patient-provider relationship mediates the link between adult attachment and self-management among primary care patients with multiple chronic diseases. 209 patients with a minimum of three chronic diseases (including type II diabetes, hypertension and at least one other chronic condition) between the ages of 50 and 85 from eight general practices were included in the APRICARE cohort study. Adult attachment was measured via self-report (ECR-RD), self-management skills by the FERUS and the patient-provider relationship by the PRA-D. The health status and chronicity were assessed by the GP. Multiple mediation analyses were used to examine whether aspects of the patient-provider relationship (communication, information, affectivity) are a mediators of associations between adult attachment and self-management. The analysis revealed that the quality of the patient-provider relationship mediated the effect of attachment on self-management in patients with multiple chronic conditions. Particularly the quality of communication and information over the course of treatment has a significant mediating influence. A personalized, attachment-related approach that promotes active patient-provider communication and gives information about the treatment to the patient may improve self-management skills in patients.

    While efficacy of massage and other nonpharmacological treatments for chronic low back pain is established, stakeholders have called for pragmatic studies of effectiveness in "real-world" primary health care. The Kentucky Pain Research and Outcomes Study evaluated massage impact on pain, disability, and health-related quality of life for primary care patients with chronic low back pain. We report effectiveness and feasibility results, and make comparisons with established minimal clinically important differences. Primary care providers referred eligible patients for 10 massage sessions with community practicing licensed massage therapists. Oswestry Disability Index and SF-36v2 measures obtained at baseline and postintervention at 12 and 24 weeks were analyzed with mixed linear models and Tukey's tests. Additional analyses examined clinically significant improvement and predictive patient characteristics. Of 104 enrolled patients, 85 and 76 completed 12 and 24 weeks of data collection, respectively. Group means improved at 12 weeks for all outcomes and at 24 weeks for SF-36v2's Physical Component Summary and Bodily Pain Domain. Of those with clinically improved disability at 12 weeks, 75% were still clinically improved at 24 weeks ( P  < 0.01). For SF-36v2 Physical and Mental Component Summaries, 55.4% and 43.4%, respectively, showed clinically meaningful improvement at 12 weeks, 46.1% and 30.3% at 24 weeks. For Bodily Pain Domain, 49.4% were clinically improved at 12 weeks, 40% at 24 weeks. Adults older than age 49 years had better pain and disability outcomes than younger adults. Results provide a meaningful signal of massage effect for primary care patients with chronic low back pain and call for further research in practice settings using pragmatic designs with control groups. © 2017 American Academy of Pain Medicine.

    Aim of the study: to evaluate the effectiveness of the techniques of dynamic simultaneous transcranial magnetic therapy and resonance, and electrical stimulation, transcranial magnetic therapy and dynamic laser stimulation, magnetic simpatokorrektsii in the treatment of patients with primary open-angle glaucoma with chronic cerebral ischemia. Techniques. We observed 184 patients diagnosed with primary open-angle glaucoma who received different physical therapy techniques. Results. Patients treated with transcranial magnetic therapy and electrical stimulation or laser stimulation, in addition to improving visual function and improve the bioelectrical activity of the visual cortex, more pronounced than in other groups also observed the activation of the intraocular blood fow. Application of magnetic simpatokorrektsii allows for improvement of basic functional, electrophysiological and hemodynamic performance by reducing the activity of the sympathetic nervous system and reduce the vasopressor effect. Conclusion. Transcranial magnetic therapy in combination with electrical stimulation or laser stimulation is effective in the treatment of patients with POAG. In patients with primary open-angle glaucoma with chronic cerebral ischemia technique of magnetic sim-patokorrektsii compared with traditional methods of vasoactive therapy is more effective, which is manifested not only increase the visual functions, but also a decrease in cognitive impairment.

    In primary care, patients with chronic kidney disease (CKD) are frequently prescribed excessive doses of antibiotics relative to their kidney function. We examined whether nephrology comanagement is associated with improved prescribing in primary care. In a retrospective propensity score-matched cross-sectional study, we studied the appropriateness of antibiotic prescriptions by primary care physicians to Ontarians ≥66 years of age with CKD Stages 4 and 5 (estimated glomerular filtration rate <30 mL/min/1.73 m2 not receiving dialysis) from 1 April 2003 to 31 March 2014. Comanagement was defined as having at least one outpatient visit with a nephrologist within the year prior to antibiotic prescription date. We compared the rate of appropriately dosed antibiotics in primary care between 3937 patients who were comanaged by a nephrologist and 3937 patients who were not. Only 1184 (30%) of 3937 noncomanaged patients had appropriately dosed antibiotic prescriptions prescribed by a primary care physician. Nephrology comanagement was associated with an increased likelihood that an appropriately dosed prescription was prescribed by a primary care physician; however, the magnitude of the effect was modest [1342/3937 (34%); odds ratio 1.20 (95% confidence interval 1.09-1.32); P < 0.001]. The majority of antibiotics prescribed by primary care physicians are inappropriately dosed in CKD patients, whether or not a nephrologist is comanaging the patient. Nephrologists have an opportunity to increase awareness of appropriate dosing of medications in primary care through the patients they comanage.

    Nutrition is an important aspect of chronic disease prevention and management by primary health professionals, including GPs, dietitians, practice nurses, diabetes educators and exercise professionals. In order to better understand how to improve the delivery of nutrition care, it is important to have valid and reliable tools to measure self-perceived competence. This study aimed to develop a valid, structured, questionnaire that measures the self-perceived competence of primary health professionals to provide nutrition care to patients with chronic disease. The development of the questionnaire was carried out in four stages (1): preparation of scope and structure, through a literature review and consultation with an expert reference group (2); development of questionnaire items, which were refined through feedback from the reference group and 18 primary health professionals (3); investigation of internal consistency and concurrent validity through a pilot study on 118 primary health professionals (4) and investigation of test-retest reliability through a pilot study on 33 primary health professionals who completed the questionnaire twice, 2-3 weeks apart. Stages 1 and 2 resulted in four constructs and 35 questions in the questionnaire. Stage 3 confirmed internal consistency, with Cronbach's α ranging from 0.88 to 0.98 for each construct and 0.98 for all items combined. Dietitians scored significantly higher than speech pathologists (P COMPetence (NUTCOMP) questionnaire is a valid, reliable and suitable tool that can be used to directly inform professional development and identify opportunities to support safe and effective practice. © The Author 2015.

    Full Text Available BACKGROUND: Our interest in chronic conditions is due to the fact that, worldwide, chronic diseases have overtaken infectious diseases as the leading cause of death and disability, so their management represents an important challenge for health systems. The aim of this study was to compare the performance of primary health care services in managing diabetes, congestive heart failure (CHF and coronary heart disease (CHD, by age group. METHODS: This population-based retrospective cohort study was conducted in Italy, enrolling 1,948,622 residents ≥ 16 years old. A multilevel regression model was applied to analyze compliance to care processes with explanatory variables at both patient and district level, using age group as an independent variable, and adjusting for sex, citizenship, disease duration, and Charlson index on the first level, and for District Health Unit on the second level. RESULTS: The quality of chronic disease management showed an inverted U-shaped relationship with age. In particular, our findings indicate lower levels for young adults (16-44 year-olds, adults (45-64, and oldest old (+85 than for patients aged 65-74 in almost all quality indicators of CHD, CHF and diabetes management. Young adults (16-44 y, adults (45-64 y, the very old (75-84 y and the oldest old (+85 y patients with CHD, CHF and diabetes are less likely than 65-74 year-old patients to be monitored and treated using evidence-based therapies, with the exceptions of echocardiographic monitoring for CHF in young adult patients, and renal monitoring for CHF and diabetes in the very old. CONCLUSION: Our study shows that more effort is needed to ensure that primary health care systems are sensitive to chronic conditions in the young and in the very elderly.

    Assessment of vitamin D levels and deficiency status in individuals with chronic low back pain (CLBP) in a Swedish general population, compared with controls matched for sex and age. Cross-sectional case-control study. Primary care, southern Sweden. Participants (n = 44) with self-reported low back pain for at least 3 months and individually sex- and age-matched controls without a chronic pain condition (n = 44), recruited from the general population by random letter of invitation. Association between vitamin D level and CLBP when adjusting for possible confounders in a multivariate forward conditional logistic regression model. Mean S-25-hydroxyvitamin D levels were 81 and 80 nmol/L in the CLBP and control group, respectively. The prevalence of vitamin D deficiency was low and similar in the CLBP group and the control group. Vitamin D level was not associated with CLBP when potential confounders were taken into account. No difference in vitamin D levels between participants with CLBP and matched controls could be demonstrated in the present sample. Assessment of vitamin D level and deficiency status may be of questionable value in the management of CLBP in primary care settings at similar latitudes, unless there are additional risk factors for deficiency or specific indicators of osteomalacia. Key points Vitamin D deficiency is common and reported in many chronic pain conditions, including chronic low back pain (CLBP), but evidence for an association and causality is insufficient. • The present study found no association between vitamin D levels and CLBP in a case-control sample of 44 + 44 individuals from the Swedish general population. • Prevalence of vitamin D deficiency was low and comparable in individuals with CLBP and controls without chronic pain, matched for sex and age. • Assessment of vitamin D status, for the purpose of finding and treating an underlying cause of pain, may be of limited value in the management of CLBP in

    Chronic obstructive pulmonary disease (COPD) remains a major health problem, strongly related to smoking. Despite the publication of practice guidelines on prevention and treatment, not all patients with the disease receive the recommended healthcare, particularly with regard to smoking cessation advice where applicable. We have developed a tailored implementation strategy for enhancing general practitioners' adherence to the disease management guidelines. The primary aim of the study is to evaluate the effects of this tailored implementation intervention on general practitioners' adherence to guidelines. A pragmatic two-arm cluster randomized trial has been planned to compare care following the implementation of tailored interventions of four recommendations in COPD patients against usual care. The study will involve 18 general practices (9 in the intervention group and 9 in the control group) in Poland, each with at least 80 identified (at the baseline) patients with diagnosed COPD. The nine control practices will provide usual care without any interventions. Tailored interventions to implement four recommendations will be delivered in the remaining nine practices. At follow-up after nine months, data will be collected for all 18 general practices. The primary outcome measure is physicians' adherence to all four recommendations: brief anti-smoking advice, dyspnea assessment, care checklist utilization and demonstration to patients of correct inhaler use. This measurement will be based on data extracted from identified patients' records. Additionally, we will survey and interview patients with chronic obstructive pulmonary disease about the process of care. The results of this trial will be directly applicable to primary care in Poland and add to the growing body of evidence on interventions to improve chronic illness care. This trial has been registered with Clinical Trials Protocol Registration System. NCT01893476.

    Ro 15-4513 (ethyl-8-azido-5, 6-dihydro-5-methyl-6-oxo-4H-imidazo [1,5α], [1,4] benzodiazepine-3-carboxylate) is reported to be a selective ethanol antagonist in biochemical and behavioral studies. The effect of chronic ethanol treatment on the binding of [ 3 H]Ro 15-4513 was investigated in cultured spinal cord neurons, which are shown to possess all the elements of GABA benzodiazepine receptor complex. Chronic ethanol treatment (50 mM for 6 hr, 12 hr, 18 hr, 3 days, and 5 3 days) produced an increase in the specific binding of [ 3 H]Ro 15-4513. The increase in binding in these neurons was due to an increase in the number (B max ) of receptor sites. This effect was specific for Ro 15-4513, since identical ethanol treatment did not alter the binding of benzodiazepine antagonist [ 3 H]Ro 15-1788 or agonist [ 3 H]flunitrazepam or inverse agonist [ 3 H]methyl-β-carboline-3-carboxylate. Similar results have been reported following chronic ethanol treatment to rats. These results suggest that the Ro 15-4513 binding sites on the oligomeric GABA receptor complex are altered following chronic ethanol administration, and support the notion of a unique role of Ro 15-4513 as an ethanol antagonist

    Chronic stress may produce a decrease in central NPY expression and subjects exposed to it may prove hypersensitivity to a novel stressor with dysfunctions in the NPY system and cardiovascular maladaptation to stress, even hypertension. Upregulation of NPY expression may contribute to successful behavioral adaptation to stress by reducing cardiovascular tone and suppressing anxious behaviors. Adaptogens, a new class of metabolic regulators stimulate NPY expression and release. The aim of this study is to increase tolerance and adaptation to stress of hypersensitive to novel stressor, occupational chronic stress exposed subjects with cardiovascular maladaptation to mild new stressor using adaptogens as part of prevention protocol. 40 military personnel with known cardiostressor reactional mode and occupational chronic stress exposure were exposed to mild novel stressor: occupational medicine routine evaluation and clinically assessed for maladaptative cardiovascular response prior and before application of 30 day prevention protocol. Employees were randomly split in two groups, one receiving standard prevention protocol (lifestyle counseling) plus adaptogens in multiple dose administration, twice daily and the other receiving only standard prevention protocol. We found significant statistic differences in all cardiovascular parameters in adaptogen group and only in diastolic blood pressure in control group. Adaptogens could be an important factor in successful prevention protocols of chronic occupational stress dysfunctions involving NPY systems.

    The current study prospectively investigated the optimal dose-volume condition in cases of lung cancer with chronic pulmonary disease compared to those without chronic pulmonary disease. Cases of primary lung cancer treated with intended curative radiation therapy were registered in the current study. Their fraction size was limited to 2-3 Gy, so-called standard fractionation. They were prescribed a total dose of 60 Gy for non-small cell lung cancer (NSCLC; n=17) and a total dose of 54 Gy for small cell lung cancer (SCLC; n=4). Of the 21 patients enrolled in this study, 4 had chronic pulmonary disease (study arm), and the others had no chronic pulmonary disease (control arm). Seven received chemotherapy. Symptomatic radiation pneumonitis occurred in 5. Of the four patients in the study arm, two (50%) experienced symptomatic radiation pneumonitis; only 3 of the 17 patients in the control arm (17.6%) experienced symptomatic radiation pneumonitis. Furthermore, the median V 20 of patients who experienced symptomatic radiation pneumonitis in the study arm was 14%, which was higher than that of patients with no symptomatic radiation pneumonitis in the study arm, 5.8%. On the other hand, in the control arm, the median V 20 of patients with symptomatic radiation pneumonitis was 14.2%, about the same as that of patients with no symptomatic radiation pneumonitis in the control arm, 15.1%. The current study suggested that, as much as 15% of V 20 , might play an important role in cases of lung cancer with chronic pulmonary disease. (author)

    To investigate prognostic factors for future work ability in women with chronic low back pain (CLBP) consulting primary health care. A 2-year prospective longitudinal cohort study of female patients with CLBP within the primary health care was conducted. Patients were assessed at the first assessment and after 2 years. Prognostic factors for work ability (yes/no) were analyzed by multivariate regression. A total of 130 patients were included at first assessment. After 2 years, 123 patients (95%) were followed up. The 6-minute walk test, depression, and earlier work ability predicted work ability at the 2-year follow-up. A nomogram was constructed to assess the probability of future work ability. The 6-minute walk test, work ability, and depression predicted work ability for women with CLBP after 2 years.

    To investigate changes in cortical excitability and short-term synaptic plasticity we delivered 5 Hz repetitive transcranial magnetic stimulation (rTMS) over the primary motor cortex in 11 patients with mild-to-moderate Alzheimer's disease (AD) before and after chronic therapy with rivastigmine. Resting motor threshold (RMT), motor evoked potential (MEP), cortical silent period (CSP) after single stimulus and MEP facilitation during rTMS trains were tested three times during treatment. All patients underwent neuropsychological tests before and after receiving rivastigmine. rTMS data in patients were compared with those from age-matched healthy controls. At baseline, RMT was significantly lower in patients than in controls whereas CSP duration and single MEP amplitude were similar in both groups. In patients, rTMS failed to induce the normal MEP facilitation during the trains. Chronic rivastigmine intake significantly increased MEP amplitude after a single stimulus, whereas it left the other neurophysiological variables studied unchanged. No significant correlation was found between patients' neuropsychological test scores and TMS measures. Chronic treatment with rivastigmine has no influence on altered cortical excitability and short-term synaptic plasticity as tested by 5 Hz-rTMS. The limited clinical benefits related to cholinesterase inhibitor therapy in patients with AD depend on factors other than improved plasticity within the cortical glutamatergic circuits.

    Comparison of the results from the EUROASPIRE I to the EUROASPIRE III, in patients with coronary heart disease, shows that the prevalence of uncontrolled risk factors remains high. The aim of the study was to evaluate the effectiveness of a new multifactorial intervention in order to improve health care for chronic coronary heart disease patients in primary care. In this randomized clinical trial with a 1-year follow-up period, we recruited patients with a diagnosis of coronary heart disease (145 for the intervention group and 1461 for the control group). An organizational intervention on the patient-professional relationship (centered on the Chronic Care Model, the Stanford Expert Patient Programme and the Kaiser Permanente model) and formative strategy for professionals were carried out. The main outcomes were smoking control, low-density lipoprotein cholesterol (LDL-C), systolic blood pressure (SBP) and diastolic blood pressure (DBP). A multivariate analysis was performed. The characteristics of patients were: age (68.4±11.8 years), male (71.6%), having diabetes mellitus (51.3%), dyslipidemia (68.5%), arterial hypertension (76.7%), non-smokers (76.1%); LDL-C cardiovascular risk factors control (smoking, LDL-C and SBP). Chronic care strategies may be an efficacy tool to help clinicians to involve the patients with a diagnosis of CHD to reach better outcomes. Copyright © 2014 Elsevier España, S.L.

The purpose of this study was to examine the utility of a combination of qualitative methods (Photovoice, one-on-one interviews, and focus groups in examining the daily experiences of primary care patients living with chronic pain. Methods: A sample of English-speaking primary care patients aged 30 years or older, who had been prescribed an opioid for long-term, noncancer pain management, participated in the study. Each patient took photographs that best reflected both his/her experiences with chronic pain and what he/she would like his/her life to be without chronic pain. Results: Patients submitted an average of 20.2±3.1 photographs (range =8–27 photographs. Analysis of one-on-one interviews illuminated five dominant themes: daily need for multiple medications, including opioids; difficulties climbing a flight of stairs; struggling to get out of bed in the morning; extreme challenges with participating in day-to-day life activities; and experiencing feelings of hopelessness and helplessness on a regular basis. Seven themes emerged from the focus groups: undesired effects/burdens of medications, loss of/striving for independence, effect on social interactions/relationships, pain effect on activities of daily living, constant search for convenience/a better situation, interactions with physicians, and frustration/depression with pain. Conclusion: The qualitative methods employed in this study provide deep insight into perceptions

    The aim of the study was to analyse the impact of chronic disease on the quality of life (QoL) and how QoL changes with comorbidity and socioeconomic status in persons who attend primary health care centres. The group of participants comprised 2,560 people who contacted six primary health care centres in Ankara. The level of QoL was determined by the World Health Organization Quality of Life Questionnaire Abbreviated Version (WHOQOL-BREF). Mental disorders and diabetes-hypertension comorbidity had the most negative effect on the QoL. In the physical domain of the WHOQOL-BREF, the effect of diabetes-hypertension comorbidity is greater than the additive effect of hypertension and diabetes individually. The co-occurrence of any disease with cardiovascular disease does not change QoL within any domain, except for the co-occurrence of any disease with musculoskeletal diseases which deteriorated QoL in the physical domain. The higher income and socioeconomic status corresponded to higher QoL. The effect of comorbidity on QoL can be different from the additive effects of the co-occurring diseases. Socioeconomic factors undoubtedly affect the relationship between chronic diseases and QoL, and this relationship points to health inequities among socioeconomic groups.

Observational study. 273 primary care practices in Austria, Belgium, England, Finland, France, Germany, The Netherlands, Slovenia, Switzerland and Spain. A random sample of 4563 CHD patients identified by coded diagnoses in eight countries, based on prescription lists and while visiting the practice in one country each. We performed an audit in primary care practices in 10 European countries. We used six indicators to measure key components of CVRM: risk factor recording, antiplatelet therapy, influenza vaccination, blood pressure levels (systolic organisation based on 39 items. Using multilevel regression analyses we explored the effects of practice organisation on CVRM, controlling for patient characteristics. Better overall organisation of a primary care practice was associated with higher scores on three indicators: risk factor registration (B=0.0307, porganisation was not found to be related with recorded blood pressure or cholesterol levels. Only the organisational domains 'self-management support' and 'use of clinical information systems' were linked to three CVRM indicators. A better organisation of a primary care practice was associated with better scores on process indicators of CVRM in CHD patients, but not on intermediate patient outcome measures. Direct support for patients and clinicians seemed most influential.

    Full Text Available Abstract Background Chronic non-cancer pain is a common problem that is often accompanied by psychiatric comorbidity and disability. The effectiveness of a multi-disciplinary pain management program was tested in a 3 month before and after trial. Methods Providers in an academic general medicine clinic referred patients with chronic non-cancer pain for participation in a program that combined the skills of internists, clinical pharmacists, and a psychiatrist. Patients were either receiving opioids or being considered for opioid therapy. The intervention consisted of structured clinical assessments, monthly follow-up, pain contracts, medication titration, and psychiatric consultation. Pain, mood, and function were assessed at baseline and 3 months using the Brief Pain Inventory (BPI, the Center for Epidemiological Studies-Depression Scale scale (CESD and the Pain Disability Index (PDI. Patients were monitored for substance misuse. Results Eighty-five patients were enrolled. Mean age was 51 years, 60% were male, 78% were Caucasian, and 93% were receiving opioids. Baseline average pain was 6.5 on an 11 point scale. The average CESD score was 24.0, and the mean PDI score was 47.0. Sixty-three patients (73% completed 3 month follow-up. Fifteen withdrew from the program after identification of substance misuse. Among those completing 3 month follow-up, the average pain score improved to 5.5 (p = 0.003. The mean PDI score improved to 39.3 (p Conclusions A primary care disease management program improved pain, depression, and disability scores over three months in a cohort of opioid-treated patients with chronic non-cancer pain. Substance misuse and depression were common, and many patients who had substance misuse identified left the program when they were no longer prescribed opioids. Effective care of patients with chronic pain should include rigorous assessment and treatment of these comorbid disorders and intensive efforts to insure follow up.

    Full Text Available Global health agencies estimate an increase of chronic diseases in South America. Nevertheless, few studies have investigated chronic diseases and their risk factors in the perspective of multimorbidity. This research aimed to identify these aspects in a primary health care setting of central Argentina. The Pan America version of the STEP wise approach surveillance (STEPS instrument of the World Health Organization was applied to 1044 participants, 365 men and 679 women, with a mean age of 43 years. High prevalence of overweight (33.5%, obesity (35.2%, central obesity (54%, dyslipidemia (43.5%, metabolic syndrome (21.1%, low intake of fruit and vegetables (91.8%, low levels of physical activity (71.5%, risky alcohol consumption (28%, and smoking (22.5% were detected. Hypertension and diabetes were the most prevalent chronic conditions and the total prevalence of multimorbidity was 33.1%, with 2, 3, 4, 5 and 6 chronic conditions found in 19.9%, 9.1%, 2.6%, 1.1% and 0.4% of the population, respectively. Multimorbidity affected 6.4% of the young, 31.7% of the adults, and 60.6% of the elderly, and was more prevalent among women, and in participants with lower levels of education. Having multimorbidity was significantly associated with obesity, central obesity, and higher concentrations of total blood cholesterol, low-density lipoprotein cholesterol, triglycerides, and glucose. A website was made available to the participants in order to share the experimental results and health-promoting information.

    Reform of the health care system in urban areas of China has prompted concerns about the utilization of Community Health Centers (CHC). This study examined which of the dominant primary care delivery models, i.e., the public CHC model, the 'gate-keeper' CHC model, or the hospital-owned CHC models, was most effective in enhancing access to and quality of care for patients with chronic illness. The case-comparison design was used to study nine health care organizations in Guangzhou, Dongguan, and Shenzhen cities within Guangdong province, China. 560 patients aged 50 or over with hypertension or diabetes who visited either CHCs or hospitals in these three cities were surveyed by using face-to-face interviews. Bivariate analyses were performed to compare quality and value of care indicators among subjects from the three cities. Multivariate analyses were used to assess the association between type of primary care delivery and quality as well as value of chronic care after controlling for patients' demographic and health status characteristics. Patients from all three cities chose their current health care providers primarily out of concern for quality of care (both provider expertise and adequate medical equipment), patient-centered care, and insurance plan requirement. Compared with patients from Guangzhou, those from Dongguan performed significantly better on most quality and value of care indicators. Most of these indicators remained significantly better even after controlling for patients' demographic and health status characteristics. The Shenzhen model (hospital-owned and -managed CHC) was generally effective in enhancing accessibility and continuity. However, coordination suffered due to seemingly duplicating primary care outpatients at the hospital setting. Significant associations between types of health care facilities and quality of care were also observed such that patients from CHCs were more likely to be satisfied with traveling time and follow-up care by

    Changes in patterns of living result in changes in the nature and causes of disease. The industrial revolution of the late 18th century, and the technological revolution of the late 20th century are cases in point. The former was associated with a decline in infectious diseases; the latter with an increase in lifestyle and environmentally induced chronic diseases . Health practices are typically modified to deal with such changes, hence the recent rise in interest in lifestyle-oriented forms of clinical practice. © 2014 John Wiley & Sons Ltd.

    New neuroimaging techniques have led to significant advancements in our understanding of cerebral mechanisms of primary insomnia. However, the neuronal low-frequency oscillation remains largely uncharacterized in chronic primary insomnia (CPI). In this study, the amplitude of low-frequency fluctuation (ALFF), a data-driven method based on resting-state functional MRI, was used to examine local intrinsic activity in 27 patients with CPI and 27 age-, sex-, and education-matched healthy controls. We examined neural activity in two frequency bands, slow-4 (between 0.027 and 0.073 Hz) and slow-5 (0.010-0.027 Hz), because blood-oxygen level dependent (BOLD) fluctuations in different low-frequency bands may present different neurophysiological manifestations that pertain to a spatiotemporal organization. The ALFF associated with the primary disease effect was widely distributed in the cerebellum posterior lobe (CPL), dorsal and ventral prefrontal cortex, anterior cingulate cortex, precuneus, somatosensory cortex, and several default-mode sub-regions. Several brain regions (i.e., the right cerebellum, anterior lobe, and left putamen) exhibited an interaction between the frequency band and patient group. In the slow-5 band, increased ALFF of the right postcentral gyrus/inferior parietal lobule (PoCG/IPL) was enhanced in association with the sleep quality (ρ = 0.414, P  = 0.044) and anxiety index (ρ = 0.406, P  = 0.049) of the CPI patients. These findings suggest that during chronic insomnia, the intrinsic functional plasticity primarily responds to the hyperarousal state, which is the loss of inhibition in sensory-informational processing. Our findings regarding an abnormal sensory input and intrinsic processing mechanism might provide novel insight into the pathophysiology of CPI. Furthermore, the frequency factor should be taken into consideration when exploring ALFF-related clinical manifestations.

    Chronic sugar-sweetened beverage (SSB) consumption is associated with obesity and type 2 diabetes mellitus (T2DM). Hyperglycaemia contributes to metabolic alterations observed in T2DM, such as reduced oxidative capacity and elevated glycolytic and lipogenic enzyme expressions in skeletal muscle tissue. We aimed to investigate the metabolic alterations induced by SSB supplementation in healthy individuals and to compare these with the effects of chronic hyperglycaemia on primary muscle cell cultures. Lightly active, healthy, lean subjects (n = 11) with sporadic soft drink consumption underwent a 4-week SSB supplementation (140 ± 15 g/day, ~2 g glucose/kg body weight/day, glucose syrup). Before and after the intervention, body composition, respiratory exchange ratio (RER), insulin sensitivity, muscle metabolic gene and protein expression were assessed. Adaptive responses to hyperglycaemia (7 days, 15 mM) were tested in primary human myotubes. SSB supplementation increased fat mass (+1.0 kg, P < 0.05), fasting RER (+0.12, P < 0.05), fasting glucose (+0.3 mmol/L, P < 0.05) and muscle GAPDH mRNA expressions (+0.94 AU, P < 0.05). PGC1α mRNA was reduced (-0.20 AU, P < 0.05). Trends were found for insulin resistance (+0.16 mU/L, P = 0.09), and MondoA protein levels (+1.58 AU, P = 0.08). Primary myotubes showed elevations in GAPDH, ACC, MondoA and TXNIP protein expressions (P < 0.05). Four weeks of SSB supplementation in healthy individuals shifted substrate metabolism towards carbohydrates, increasing glycolytic and lipogenic gene expression and reducing mitochondrial markers. Glucose-sensing protein MondoA might contribute to this shift, although further in vivo evidence is needed to corroborate this.

    Many patients with chronic heart failure (CHF), a common condition with high morbidity and mortality rates, receive treatment in primary care. To improve the management of CHF in primary care, we developed an implementation programme comprised of educational and organisational components, with support by a practice visitor and focus both on drug treatment and lifestyle advice, and on organisation of care within the practice and collaboration with other healthcare providers. Tailoring has been shown to improve the success of implementation programmes, but little is known about what would be best methods for tailoring, specifically with respect to CHF in primary care. We describe the study protocol of a cluster randomised controlled trial to examine the effectiveness of tailoring a CHF implementation programme to general practices compared to a standardised way of delivering a programme. The study population will consist of 60 general practitioners (GPs) and the CHF patients they include. GPs are randomised in blocks of four, stratified according to practice size. With a tailored implementation programme GPs prioritise the issues that will form the bases of the support for the practice visits. These may comprise several issues, both educational and organizational.The primary outcome measures are patient's experience of receiving structured primary care for CHF (PACIC, a questionnaire related to the Chronic Care Model), patients' health-related utilities (EQ-5D), and drugs prescriptions using the guideline adherence index.

    Full Text Available Abstract Background Care management programmes are an effective approach to care for high risk patients with complex care needs resulting from multiple co-occurring medical and non-medical conditions. These patients are likely to be hospitalized for a potentially "avoidable" cause. Nurse-led care management programmes for high risk elderly patients showed promising results. Care management programmes based on health care assistants (HCAs targeting adult patients with a high risk of hospitalisation may be an innovative approach to deliver cost-efficient intensified care to patients most in need. Methods/Design PraCMan is a cluster randomized controlled trial with primary care practices as unit of randomisation. The study evaluates a complex primary care practice-based care management of patients at high risk for future hospitalizations. Eligible patients either suffer from type 2 diabetes mellitus, chronic obstructive pulmonary disease, chronic heart failure or any combination. Patients with a high likelihood of hospitalization within the following 12 months (based on insurance data will be included in the trial. During 12 months of intervention patients of the care management group receive comprehensive assessment of medical and non-medical needs and resources as well as regular structured monitoring of symptoms. Assessment and monitoring will be performed by trained HCAs from the participating practices. Additionally, patients will receive written information, symptom diaries, action plans and a medication plan to improve self-management capabilities. This intervention is addition to usual care. Patients from the control group receive usual care. Primary outcome is the number of all-cause hospitalizations at 12 months follow-up, assessed by insurance claims data. Secondary outcomes are health-related quality of life (SF12, EQ5D, quality of chronic illness care (PACIC, health care utilisation and costs, medication adherence (MARS, depression

    Full Text Available Gastric volvulus is an uncommon entity found in the paediatric population. We are reporting a case of chronic gastric volvulus presented to us with the complaints of recurrent vomiting after each feed. The vomiting was projectile, nonbilious, and the content was milk. The patient was evaluated by clinical and radiological means in the form of the X-ray abdomen, ultrasound abdomen, upper gastrointestinal (GI contrast study, and computed tomography scan of the abdomen. The upper GI contrast study was suggestive of gastric volvulus. The patient was operated and gastropexy was done. There was lax gastrocolic ligament with increased distance between stomach and transverse colon without any obvious gastric volvulus. Postsurgery, the patient was symptom-free.

    Early detection of COPD may reduce the future burden of the disease. We aimed to investigate whether prescreening with a COPD-6 screening device (measuring FEV 1 and FEV 6 ) facilitates early detection of COPD in primary care. In primary care, individuals at high risk of COPD (ie, age ≥35 years, relevant exposure, and at least one respiratory symptom) and no previous diagnosis of obstructive lung disease were examined with a COPD-6 screening device. In prioritized order, the criteria for proceeding to confirmatory spirometry were FEV 1 /FEV 6 COPD regardless of test result (medical doctor's [MD] decision). Based on spirometry, including bronchodilator (BD) reversibility test, individuals were classified as COPD (post-BD FEV 1 /FVC COPD-6 screening to confirmative spirometry based on the following criteria: 510 (54%) FEV 1 /FEV 6 COPD (51%), asthma (3%), and no obstructive lung disease (45%). COPD was diagnosed in 487 (16%) of the enrolled subjects in whom confirmative spirometry was performed in 69% based on FEV 1 /FEV 6 COPD-6 device showed acceptable specificity for the selection of subjects for diagnostic spirometry and is likely to be a useful alternative to current practice in primary care.

    Full Text Available Abstract Background Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS or chronic fatigue syndrome (CFS has been used to name a range of chronic conditions characterized by extreme fatigue and other disabling symptoms. Attempts to estimate the burden of disease have been limited by selection bias, and by lack of diagnostic biomarkers and of agreed reproducible case definitions. We estimated the prevalence and incidence of ME/CFS in three regions in England, and discussed the implications of frequency statistics and the use of different case definitions for health and social care planning and for research. Methods We compared the clinical presentation, prevalence and incidence of ME/CFS based on a sample of 143,000 individuals aged 18 to 64 years, covered by primary care services in three regions of England. Case ascertainment involved: 1 electronic search for chronic fatigue cases; 2 direct questioning of general practitioners (GPs on cases not previously identified by the search; and 3 clinical review of identified cases according to CDC-1994, Canadian and Epidemiological Case (ECD Definitions. This enabled the identification of cases with high validity. Results The estimated minimum prevalence rate of ME/CFS was 0.2% for cases meeting any of the study case definitions, 0.19% for the CDC-1994 definition, 0.11% for the Canadian definition and 0.03% for the ECD. The overall estimated minimal yearly incidence was 0.015%. The highest rates were found in London and the lowest in East Yorkshire. All but one of the cases conforming to the Canadian criteria also met the CDC-1994 criteria, however presented higher prevalence and severity of symptoms. Conclusions ME/CFS is not uncommon in England and represents a significant burden to patients and society. The number of people with chronic fatigue who do not meet specific criteria for ME/CFS is higher still. Both groups have high levels of need for service provision, including health and social

    Community pharmacists (CPs) have been changing their role to focus on patient-centred services to improve the quality of chronic disease management (CDM) in primary care. However, CPs have not been readily included in collaborative CDM with other primary care professionals such as physicians. There is little understanding of the CP role change and whether it affects the utilisation of CPs in primary care collaborative CDM. To explore physician and CP perceptions of the CP's role in Australian primary care and how these perceptions may influence the quality of physician/CP CDM programmes. Data were collected from physicians and CPs using semi-structured interviews. A qualitative methodology utilising thematic analysis was employed during data analysis. Qualitative methodology trustworthiness techniques, negative case analysis and member checking were utilised to substantiate the resultant themes. A total of 22 physicians and 22 CPs were interviewed. Strong themes emerged regarding the participant perceptions of the CP's CDM role in primary care. The majority of interviewed physicians perceived that CPs did not have the appropriate CDM knowledge to complement physician knowledge to provide improved CDM compared with what they could provide on their own. Most of the interviewed CPs expressed a willingness and capability to undertake CDM; however, they were struggling to provide sustainable CDM in the business setting within which they function in the primary care environment. Role theory was selected as it provided the optimum explanation of the resultant themes. First, physician lack of confidence in the appropriateness of CP CDM knowledge causes physicians to be confused about the role CPs would undertake in a collaborative CDM that would benefit the physicians and their patients. Thus, by increasing physician awareness of CP CDM knowledge, physicians may see CPs as suitable CDM collaborators. Second, CPs are experiencing role conflict and stress in trying to change

    The aim of this study was to evaluate the efficacy and safety of ramelteon 4, 8, 16 or 32 mg and placebo in Japanese patients with chronic insomnia using a randomized, double-blind, five-period crossover design. A total of 65 Japanese patients with chronic primary insomnia received ramelteon or placebo for two nights each in sleep laboratories. Changes in sleep parameters were assessed objectively by polysomnography and subjectively by postsleep questionnaires. Safety and tolerability was evaluated by assessment of the occurrence of adverse events, next-day residual effects and laboratory and ECG investigations. Ramelteon 8 and 32 mg significantly shortened the mean latency to persistent sleep in comparison with placebo, and there was a statistically significant trend for linear dose-response for this sleep parameter. Overall changes in sleep architecture were modest (Japanese and US patients. Overall, ramelteon 8 mg showed the most favorable balance between sleep-promoting effects and tolerability. The unique efficacy profile of ramelteon, promoting sleep initiation without affecting other sleep parameters, may be due to its circadian shifting effect.

    Research has demonstrated a knowledge and practice gap in the identification and management of chronic kidney disease (CKD). In 2009, published data showed that general practices in Greater Manchester had a low detection rate for CKD. A 12-month improvement collaborative, supported by an evidence-informed implementation framework and financial incentives. 19 general practices from four primary care trusts within Greater Manchester. Number of recorded patients with CKD on practice registers; percentage of patients on registers achieving nationally agreed blood pressure targets. The collaborative commenced in September 2009 and involved three joint learning sessions, interspersed with practice level rapid improvement cycles, and supported by an implementation team from the National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care for Greater Manchester. At baseline, the 19 collaborative practices had 4185 patients on their CKD registers. At final data collection in September 2010, this figure had increased by 1324 to 5509. Blood pressure improved from 34% to 74% of patients on practice registers having a recorded blood pressure within recommended guidelines. Evidence-based improvement can be implemented in practice for chronic disease management. A collaborative approach has been successful in enabling teams to test and apply changes to identify patients and improve care. The model has proved to be more successful for some practices, suggesting a need to develop more context-sensitive approaches to implementation and actively manage the factors that influence the success of the collaborative.

    To describe some sociodemographics and clinical characteristics of subjects with Non-specific Chronic Low Back Pain (NCLBP) in Primary Care, as well as to investigate their association with Fear-Avoidance (FA). Cross-sectional. Secondary analysis of an intervention study. Basic Health Areas in Costa del Sol Health District (Málaga, Spain). An analysis was performed on 147 subjects with NCLBP from a previous intervention study database in Primary Care Physiotherapy (PCP). Characteristics: age 18-65; understanding of the Spanish language; absence of cognitive disorders, fibromyalgia or dorsolumbar surgery, and to be able to perform physical exercise. The main variable was FA level (FABQ and the FABQ-PA and FABQ-W) sub-scales. Clinical variables included: pain (NRPS-11), disability (RMQ), evolution, previous treatments and diagnostic imaging. The sociodemographic variables included: gender, age, educational level, and employment status. Just over half (51.7%) of the subjects had high FA on the FABQ-PA sub-scale. Sick leave (SL) [β=24.45 (P=.009 * ); β=13.03 (P=.016 * ); β=14.04 (P=.011 * ) for FABQ, FABQ-PA and FABQ-W, respectively]; primary studies level [β=15.09 (P=.01 * ); β=9.73 (P=.01 * ) for FABQ and FABQ-PA], and disability [β=1.45 (P<.001); β=0.61 (P<.001); β=0.68 (P<.001) for FABQ, FABQ-PA and FABQ-W, respectively] were associated with FA when they were modeled by multivariate regression. Some sociodemographic and clinical features of the NCLBP population are presented. Imaging tests (81.63%) and previous passive treatments (55.78%) could reflect problems of adherence to recommendations of CPGs. Sick leave, primary studies level, and disability were associated with FA. The findings should be interpreted in the light of possible limitations.

    The burden of chronic disease and multimorbidity is rapidly increasing. Self-management support interventions are effective in reduce cost, especially when targeted at a single disease group; however, economical evidence of such complex interventions remains scarce. The objective of this study was to evaluate a cost-effectiveness analysis of a tele-based health-coaching intervention among patients with type 2 diabetes (T2D), coronary artery disease (CAD) and congestive heart failure (CHF). A total of 1570 patients were blindly randomized to intervention (n = 970) and control (n = 470) groups. The intervention group received monthly individual health coaching by telephone from a specially trained nurse for 12-months in addition to routine social and healthcare. Patients in the control group received routine social and health care. Quality of life was assessed at the beginning of the intervention and follow-up measurements were made after 12 months health coaching. The cost included all direct health-care costs supplemented with home care and nursing home-care costs in social care. Utility was based on a Health Related Quality of Life (HRQoL) measurement (15D instrument), and cost effectiveness was assessed using incremental cost-effectiveness ratios (ICERs). The cost-effectiveness of health coaching was highest in the T2D group (ICER €20,000 per Quality-Adjusted Life Years [QALY]). The ICER for the CAD group was more modest (€40,278 per QALY), and in the CHF group, costs increased with no marked effect on QoL. Probabilistic sensitivity analysis indicated that at the societal willingness to pay threshold of €50,000 per QALY, the probability of health coaching being cost effective was 55% in the whole study group. The cost effectiveness of health coaching may vary substantially across patient groups, and thus interventions should be targeted at selected subgroups of chronically ill. Based on the results of this study, health coaching improved the QoL of

    Full Text Available Gut-associated immune system has been identified as a major battlefield during the early phases of HIV infection. γδ T-cells, deeply affected in number and function after HIV infection, are able to act as a first line of defence against invading pathogens by producing antiviral soluble factors and by killing infected cells. Despite the relevant role in mucosal immunity, few data are available on gut-associated γδ T-cells during HIV infection. Aim of this work was to evaluate how primary (P-HIV and chronic (C-HIV HIV infection affects differentiation profile and functionality of circulating and gut-associated Vδ1 and Vδ2 T-cells. In particular, circulating and mucosal cells were isolated from respectively whole blood and residual gut samples from HIV-infected subjects with primary and chronic infection and from healthy donors (HD. Differentiation profile and functionality were analyzed by multiparametric flow cytometry. P-HIV and C-HIV were characterized by an increase in the frequency of effector Vδ1-T cells both in circulating and mucosal compartments. Moreover, during P-HIV mucosal Vδ1 T-cells expressed high levels of CD107a, suggesting a good effector cytotoxic capability of these cells in the early phase of infection that was lost in C-HIV. P-HIV induced an increase in circulating effector Vδ2 T-cells in comparison to C-HIV and HD. Notably, P-HIV as well as HD were characterized by the ability of mucosal Vδ2 T-cells to spontaneously produce IFN-γ that was lost in C-HIV. Altogether, our data showed for the first time a functional capability of mucosal Vδ1 and Vδ2 T-cells during P-HIV that was lost in C-HIV, suggesting exhaustion mechanisms induced by persistent stimulation.

    The concepts of "power" and "empowerment" are used in various disciplines, both political and social. Now are these terms frequently in the field of health. Our goal is to know its meaning as a synonym of expressions: "energy", "force", "domain", "vigour", "power", "capacity", "authority" and "control", which have been always within our practice nurse's own lexicon. Semantically analyzing them will help us in the understanding of its nuance. The literature review facilitates their understanding and allows us to link these words within the management of care. In this way we can propose diagnoses, interventions and outcomes specifically related to these concepts, which will help us optimize the efficiency in the management of care plans. The purpose of various collective nurses from different institutions is that the person is able to not generate dependencies and have the option of choosing your own lifestyle according to their culture and environment, independently or with the help. Generate knowledge is to generate power. The person should be educated and informed, to be expert and active and taking action to help control and minimize the progression of your health problem chronic and its possible complications. We are in the process of reformulation of the health system, whether it is private or public, and is necessary to know the power of the various actors involved in the management of the care to us. Each of these main actors--person ill, family/caregiver or nurse--has to know what is his role in this process.

    People with addictive disorders commonly do not receive efficacious medications. Chronic care management (CCM) is designed to facilitate delivery of effective therapies. Using data from the CCM group in a trial testing its effectiveness for addiction (n=282), we examined factors associated with the prescription of addiction medications. Among participants with alcohol dependence, 17% (95%CI 12.0–22.1%) were prescribed alcohol dependence medications. Among those with drug dependence, 9% (95%CI 5.5–12.6%) were prescribed drug dependence medications. Among those with opioids as a substance of choice, 15% (95%CI 9.3–20.9%) were prescribed opioid agonist therapy. In contrast, psychiatric medications were prescribed to 64% (95%CI 58.2–69.4%). Absence of co-morbid drug dependence was associated with prescription of alcohol dependence medications. Lower alcohol addiction severity and recent opioid use were associated with prescription of drug dependence medications. Better understanding of infrequent prescription of addiction medications, despite a supportive clinical setting, might inform optimal approaches to delivering addiction medications. PMID:25524751

    Guideline committees have identified the need for research to inform the provision of conservative care for older adults with stage 5 chronic kidney disease (CKD) who have a high burden of comorbidity or functional impairment. We will use both qualitative and quantitative methodologies to provide a comprehensive understanding of barriers and facilitators to care for these patients in primary care. Our objectives are to (1) interview primary care physicians to determine their perspectives of conservative care for older adults with stage 5 CKD and (2) survey primary care physicians to determine the prevalence of key barriers and facilitators to provision of conservative care for older adults with stage 5 CKD. A sequential exploratory mixed methods design was adopted for this study. The first phase of the study will involve fundamental qualitative description and the second phase will be a cross-sectional population-based survey. The research is conducted in Alberta, Canada. The participants are primary care physicians with experience in providing care for older adults with stage 5 CKD not planning on initiating dialysis. The first objective will be achieved by undertaking interviews with primary care physicians from southern Alberta. Participants will be selected purposively to include physicians with a range of characteristics (e.g., age, gender, and location of clinical practice). Interviews will be recorded, transcribed verbatim, and analyzed using conventional content analysis to generate themes. The second objective will be achieved by undertaking a population-based survey of primary care physicians in Alberta. The questionnaire will be developed based on the findings from the qualitative interviews and pilot tested for face and content validity.

    The use of value metrics is often dependent on payer-initiated health care management incentives. There is a need for practices to define and manage their own patient panels regardless of payer to participate effectively in population health management. A key step is to define a panel of primary care patients with high comorbidity profiles. Our sample included all patients seen in an urban academic family medicine clinic over a two-year period. The simplified risk stratification was built using internal electronic health record and billing system data based on ICD-9 codes. There were 347 patients classified as high-risk out of the 5,364 patient panel. Average age was 59 years (SD 15). Hypertension (90%), hyperlipidemia (62%), and depression (55%) were the most common conditions among high-risk patients. Simplified risk stratification provides a feasible option for our team to understand and respond to the nuances of population health in our underserved community.

    With advancing age, the functional reserve of many organs tends to decrease. In particular, the lean body mass, the levels of serum albumin, the blood flow to the liver, and the glomerular filtration rate are reduced in elderly individuals and can be further impaired by the concomitant presence of acute or chronic kidney disease. Moreover, patients with kidney disease are often affected by comorbid processes and are prescribed multiple medications. The aging process also modifies some drug interactions, including the affinity of some drugs for their receptor, the number of receptors, and the cell responses upon receptor activation. Therefore, older patients with kidney disease are particularly susceptible to the risks of adverse drug reactions. Planning a pharmacological regimen in such patients is confounded by the paucity of information available on the pharmacokinetic and pharmacodynamic profiles of a large number of drugs commonly used in this group of patients. Finally, many aged patients suffer from unintentional poor compliance. In this review, the problems physicians face in designing safe and effective medication management in elderly individuals are discussed, paying attention to those more frequently used, which may be potentially harmful in patients with kidney disease. The risks of overdosing and underdosing are outlined, and some recommendations to reduce the risk of adverse drug reactions are provided. A review of the literature covering the field of drug management in older patients with kidney disease was performed by selecting those articles published between January 1, 1990, and December 1, 2014, using PubMed as a search engine with the keywords elderly, kidney disease, drugs, drug interaction, and renal function.

    Because posttraumatic stress disorder (PTSD) is both prevalent and underrecognized, routine primary care-based screening for PTSD has been implemented across the Veterans Health Administration. PTSD is frequently complicated by the presence of comorbid chronic pain, and patients with both conditions have increased symptom severity and poorer prognosis. Our objective was to determine whether the presence of pain affects diagnosis and treatment of PTSD among Department of Veterans Affairs (VA) patients who have a positive PTSD screening test. This retrospective cohort study used clinical and administrative data from six Midwestern VA medical centers. We identified 4,244 VA primary care patients with a positive PTSD screen and compared outcomes for those with and without a coexisting pain diagnosis. Outcomes were three clinically appropriate responses to positive PTSD screening: (1) mental health visit, (2) PTSD diagnosis, and (3) new selective serotonin reuptake inhibitor (SSRI) prescription. We found that patients with coexisting pain had a lower rate of mental health visits than those without pain (hazard ratio: 0.889, 95% confidence interval: 0.821-0.962). There were no significant differences in the rate of PTSD diagnosis or new SSRI prescription between patients with and without coexisting pain.

    There is much description in the literature of how patients with chronic obstructive pulmonary disease (COPD) manage their breathlessness and engage in self-care activities; however, little of this is from the perspective of those with less severe disease, who are primarily managed in primary care. This study aimed to understand the self-care experiences of patients with COPD who are primarily managed in primary care, and to examine the challenges of engaging in such behaviors. Semistructured interviews were carried out with 15 patients with COPD as part of a larger project evaluating a self-management intervention. Thematic analysis was supported by NVivo software (version 8, QSR International, Melbourne, Australia). Three main themes are described, ie, experiencing and understanding symptoms of COPD, current self-care activities, and the importance of family perceptions in managing COPD. Self-care activities evolved spontaneously as participants experienced symptoms of COPD. However, there was a lack of awareness about whether these strategies would impact upon symptoms. Perceptions of COPD by family members posed a challenge to self-care for some participants. Health care professionals should elicit patients' prior disease experiences and utilize spontaneous attempts at disease management in future self-management. These findings have implications for promoting self-management and enhancing quality of life.

    To identify predictors for the discrimination of intrahepatic cholangiocarcinoma (IMCC) and combined hepatocellular-cholangiocarcinoma (CHC) from hepatocellular carcinoma (HCC) for primary liver cancers on gadoxetic acid-enhanced MRI among high-risk chronic liver disease (CLD) patients using classification tree analysis (CTA). A total of 152 patients with histopathologically proven IMCC (n = 40), CHC (n = 24) and HCC (n = 91) were enrolled. Tumour marker and MRI variables including morphologic features, signal intensity, and enhancement pattern were used to identify tumours suspicious for IMCC and CHC using CTA. On CTA, arterial rim enhancement (ARE) was the initial splitting predictor for assessing the probability of tumours being IMCC or CHC. Of 43 tumours that were classified in a subgroup on CTA based on the presence of ARE, non-intralesional fat, and non-globular shape, 41 (95.3 %) were IMCCs (n = 29) or CHCs (n = 12). All 24 tumours showing fat on MRI were HCCs. The CTA model demonstrated sensitivity of 84.4 %, specificity of 97.8 %, and accuracy of 92.3 % for discriminating IMCCs and CHCs from HCCs. We established a simple CTA model for classifying a high-risk group of CLD patients with IMCC and CHC. This model may be useful for guiding diagnosis for primary liver cancers in patients with CLD.

    Full Text Available (1 Background: In 2011, new chronic disease guidelines were introduced across Mongolia. No formal advice was provided regarding role delineation. This study aimed to analyse the roles that different primary care providers adopted, and the variations in these, in the implementation of the guidelines in urban Mongolia; (2 Methods: Ten group interviews with nurses and ten individual interviews each with practice doctors and practice directors were conducted. Data was analysed using a thematic approach based on the identified themes relevant to role delineation; (3 Results: There was some variability and flexibility in role delineation. Factors involving teamwork, task rotation and practice flexibility facilitated well the guideline implementation. However, factors including expectations and decision making, nursing shortage, and training gaps adversely influenced in the roles and responsibilities. Some role confusion and dissatisfaction was identified, often associated with a lack of training or staff turnover; (4 Conclusions: Findings suggest that adequate ongoing training is required to maximize the range of roles particular provider types, especially primary care nurses, are competent to perform. Ensuring that role delineation is specified in guidelines could remove confusion and enhance implementation of such guidelines.

    Full Text Available Abstract Background Subacromial disorders are considered to be one of the most common pathologies affecting the shoulder. Optimal therapy for shoulder pain (SP in primary care is yet unknown, since clinical history and physical examination do not provide decisive evidence as to the patho-anatomical origin of the symptoms. Optimal decision strategies can be furthered by applying ultrasound imaging (US, an accurate method in diagnosing SP, demonstrating a clear relationship between diagnosis and available therapies. Yet, the clinical cost-effectiveness of applying US in the management of SP in primary care has not been studied. The aim of this paper is to describe the design and methods of a trial assessing the cost-effectiveness of ultrasound imaging as a diagnostic triage tool to improve management of primary care patients with non-chronic shoulder pain. Methods/Design This randomised controlled trial (RCT will involve 226 adult patients with suspected subacromial disorders recruited by general practitioners. During a Qualification period of two weeks, patients receive care as usual as advised by the Dutch College of General Practitioners, and patients are referred for US. Patients with insufficient improvement qualify for the RCT. These patients are then randomly assigned to the intervention or the control group. The therapies used in both groups are the same (corticosteroid injections, referral to a physiotherapist or orthopedic surgeon except that therapies used in the intervention group will be tailored based on the US results. Ultrasound diagnosed disorders include tendinopathy, calcific tendinitis, partial and full thickness tears, and subacromial bursitis. The primary outcome is patient-perceived recovery at 52 weeks, using the Global Perceived Effect questionnaire. Secondary outcomes are disease specific and generic quality of life, cost-effectiveness, and the adherence to the initial applied treatment. Outcome measures will be assessed

    Chronic disease management presents enormous challenges to the primary care workforce because of the rising epidemic of cardiovascular risk factors. The chronic care model was proven effective in improving chronic disease outcomes in developed countries, but there is little evidence of its effectiveness in developing countries. The aim of this study was to evaluate the effectiveness of the EMPOWER-PAR intervention (multifaceted chronic disease management strategies based on the chronic care model) in improving outcomes for type 2 diabetes mellitus and hypertension using readily available resources in the Malaysian public primary care setting. This paper presents the study protocol. A pragmatic cluster randomised controlled trial using participatory action research is underway in 10 public primary care clinics in Selangor and Kuala Lumpur, Malaysia. Five clinics were randomly selected to provide the EMPOWER-PAR intervention for 1 year and another five clinics continued with usual care. Each clinic consecutively recruits type 2 diabetes mellitus and hypertension patients fulfilling the inclusion and exclusion criteria over a 2-week period. The EMPOWER-PAR intervention consists of creating/strengthening a multidisciplinary chronic disease management team, training the team to use the Global Cardiovascular Risks Self-Management Booklet to support patient care and reinforcing the use of relevant clinical practice guidelines for management and prescribing. For type 2 diabetes mellitus, the primary outcome is the change in the proportion of patients achieving HbA1c diabetes mellitus, the primary outcome is the change in the proportion of patients achieving blood pressure care and prescribing patterns. Patients' assessment of their chronic disease care and providers' perceptions, attitudes and perceived barriers in care delivery and cost-effectiveness of the intervention are also evaluated. Results from this study will provide objective evidence of the effectiveness and

    Pulmonary hemorrhage (PH) occurs in 2-5% of SLE patients, and is associated with a high mortality rate (79-90%). Diagnostic criteria for this complication include: 1) Pulmonary infiltrates, with at least ¾ of lung tissue involved in a chest x ray, 2) Acute respiratory failure, 3) A decrease of 3g/dL or more in hemoglobin levels. PH might lead to organized pneumonia, collagen deposition, and pulmonary fibrosis which in time might cause changes in pulmonary function tests with either restrictive or obstructive patterns. To evaluate the existence of abnormalities in pulmonary function tests after a PH episode. We included patients with SLE and primary vasculitis that developed PH. During the acute episode, we measured SLEDAI in SLE patients, five factor score in microscopic polyangiitis (MPA) and Birmingham Vasculitis Activity Store (BVAS) in granulomatosis with polyangiitis (GPA) (Wegener). We determined the number of PH events, treatment, and ventilator assistance requirements and correlated its association with abnormal pulmonary function tests. We included 10 patients, 7 with SLE, 2 with MPA and 1 with GPA (Wegener). The mean activity measures were: SLEDAI 20.4 ± 7.5, FFS 2, and BVAS 36. Treatment consisted in methylprednisolone (MPD) in 3 patients, MPD plus cyclophosphamide (CY) in 6 patients, and MPD, CY, IV immunoglobulin, and plasmapheresis in one patient. Five patients required ventilatory support. We found abnormalities in pulmonary function tests in 8 patients, three had an obstructive pattern and five a restrictive pattern; 2 patients did not show any change. We did not find a significant association with any of the studied variables. PH might cause abnormalities in pulmonary function tests and prolonged immunosuppressive treatment could be required.

    Advances in neuroimaging have enabled the mapping of white matter connections across the entire brain, allowing for a more thorough examination of the extent of white matter disconnection after stroke. To assess how cortical disconnection contributes to motor impairments, we examined the relationship between structural brain connectivity and upper and lower extremity motor function in individuals with chronic stroke. Forty-three participants [mean age: 59.7 (±11.2) years; time poststroke: 64.4 (±58.8) months] underwent clinical motor assessments and MRI scanning. Nonparametric correlation analyses were performed to examine the relationship between structural connectivity amid a subsection of the motor network and upper/lower extremity motor function. Standard multiple linear regression analyses were performed to examine the relationship between cortical necrosis and disconnection of three main cortical areas of motor control [primary motor cortex (M1), premotor cortex (PMC), and supplementary motor area (SMA)] and motor function. Anatomical connectivity between ipsilesional M1/SMA and the (1) cerebral peduncle, (2) thalamus, and (3) red nucleus were significantly correlated with upper and lower extremity motor performance (P ≤ 0.003). M1-M1 interhemispheric connectivity was also significantly correlated with gross manual dexterity of the affected upper extremity (P = 0.001). Regression models with M1 lesion load and M1 disconnection (adjusted for time poststroke) explained a significant amount of variance in upper extremity motor performance (R 2  = 0.36-0.46) and gait speed (R 2  = 0.46), with M1 disconnection an independent predictor of motor performance. Cortical disconnection, especially of ipsilesional M1, could significantly contribute to variability seen in locomotor and upper extremity motor function and recovery in chronic stroke.

    To determine the impact of an educational program to improve the management of chronic obstructive pulmonary disease (COPD) that contributes to an increase of the quality of life, exercise capacity, level of dyspnoea, and clinical risk. Intervention study without controls. Primary Healthcare Centre. 193 patients with COPD were invited, 73 accepted and 55 participated in the educational program. Respiratory rehabilitation educational program with basic concepts of pulmonary and respiratory pathophysiology, respiratory physiotherapy exercises, practical workshop on the use of the most frequent inhalation devices, understanding of chronic disease and self-care measures in case of exacerbation. The quality of life (the COPD assessment test), exercise tolerance (the Six-Minute Walk Test), rating of perceived exertion (Borg Dyspnoea Score) and clinical risk (BODE index) were assessed by means of validated questionnaires in Spanish. A total of 43 (78.2%) participants completed the program. An improvement in the quality of life by a mean of 3.3 points was observed (95%CI; 1.76-4.84). Just over half (53.5%) of the participants obtained a clinically relevant improvement. Participants also improved their physical exercise capacity at post-intervention by increasing the distance that they walked in 6min by a mean of 20.76m (95%CI; 2.57-38.95). Improvements in the level of dyspnoea and clinical risk were also observed. The educational program shows a statistically significant and clinically relevant improvement in the quality of life, fatigue, symptomatology, exercise capacity, level of dyspnoea, and clinical risk. The program is adaptable to the health care routine of healthcare centres. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    Menopausal hormone therapy to prevent chronic conditions is currently not recommended because of its adverse effects. To update evidence about the effectiveness of hormone therapy in reducing risk for chronic conditions and adverse effects, and to examine whether outcomes vary among women in different subgroups. MEDLINE (January 2002 to November 2011), Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews (through the 3rd quarter of 2011), Scopus, and reference lists. Randomized, placebo-controlled trials of menopausal hormone therapy published in English since 2002 that assessed primary prevention of chronic conditions. Investigators extracted data on participants, study design, analysis, follow-up, and results; 2 investigators independently rated study quality by using established criteria. 9 fair-quality trials met the inclusion criteria. The Women's Health Initiative reported most of the results, had 11 years of follow-up, and had data most applicable to postmenopausal women in the United States. It showed that estrogen plus progestin therapy reduced fractures (46 fewer per 10 000 woman-years) and increased invasive breast cancer (8 more per 10 000 woman-years), stroke (9 more per 10 000 woman-years), deep venous thrombosis (12 more per 10 000 woman-years), pulmonary embolism (9 more per 10 000 woman-years), lung cancer death (5 more per 10 000 woman-years), gallbladder disease (20 more per 10 000 woman-years), dementia (22 more per 10 000 woman-years), and urinary incontinence (872 more per 10 000 woman-years). Estrogen-only therapy reduced fractures (56 fewer per 10 000 woman-years), invasive breast cancer (8 fewer per 10 000 woman-years), and death (2 fewer per 10 000 woman-years) and increased stroke (11 more per 10 000 woman-years), deep venous thrombosis (7 more per 10 000 woman-years), gallbladder disease (33 more per 10 000 woman-years), and urinary incontinence (1271 more per 10 000 woman-years).

    To assess the cost-effectiveness of a structured education pulmonary rehabilitation programme (SEPRP) for chronic obstructive pulmonary disease (COPD) relative to usual practice in primary care. The programme consisted of group-based sessions delivered jointly by practice nurses and physiotherapists over 8 weeks. Cost-effectiveness and cost-utility analysis alongside a cluster randomised controlled trial. 32 general practices in Ireland. 350 adults with COPD, 69% of whom were moderately affected. Intervention arm (n=178) received a 2 h group-based SEPRP session per week over 8 weeks delivered jointly by a practice nurse and physiotherapist at the practice surgery or nearby venue. The control arm (n=172) received the usual practice in primary care. Incremental costs, Chronic Respiratory Questionnaire (CRQ) scores, quality-adjusted life years (QALYs) gained estimated using the generic EQ5D instrument, and expected cost-effectiveness at 22 weeks trial follow-up. The intervention was associated with an increase of €944 (95% CIs 489 to 1400) in mean healthcare cost and €261 (95% CIs 226 to 296) in mean patient cost. The intervention was associated with a mean improvement of 1.11 (95% CIs 0.35 to 1.87) in CRQ Total score and 0.002 (95% CIs -0.006 to 0.011) in QALYs gained. These translated into incremental cost-effectiveness ratios of €850 per unit increase in CRQ Total score and €472 000 per additional QALY gained. The probability of the intervention being cost-effective at respective threshold values of €5000, €15 000, €25 000, €35 000 and €45 000 was 0.980, 0.992, 0.994, 0.994 and 0.994 in the CRQ Total score analysis compared to 0.000, 0.001, 0.001, 0.003 and 0.007 in the QALYs gained analysis. While analysis suggests that SEPRP was cost-effective if society is willing to pay at least €850 per one-point increase in disease-specific CRQ, no evidence exists when effectiveness was measured in QALYS gained.

    Full Text Available Abstract Background NICE guidelines emphasise the need for a confident, early diagnosis of Chronic Fatigue Syndrome/ Myalgic Encephalitis (CFS/ME in Primary Care with management tailored to the needs of the patient. Research suggests that GPs are reluctant to make the diagnosis and resources for management are currently inadequate. This study aimed to develop resources for practitioners and patients to support the diagnosis and management of CFS/ME in primary care. Methods Semi structured interviews were conducted with patients, carers, GPs, practice nurses and CFS/ME specialists in North West England. All interviews were audio recorded, transcribed and analysed qualitatively using open explorative thematic coding. Two patient involvement groups were consulted at each stage of the development of resources to ensure that the resources reflect everyday issues faced by people living with CFS/ME. Results Patients and carers stressed the importance of recognising CFS/ME as a legitimate condition, and the need to be believed by health care professionals. GPs and practice nurses stated that they do not always have the knowledge or skills to diagnose and manage the condition. They expressed a preference for an online training package. For patients, information on getting the most out of a consultation and the role of carers was thought to be important. Patients did not want to be overloaded with information at diagnosis, and suggested information should be given in steps. A DVD was suggested, to enable information sharing with carers and family, and also for those whose symptoms act as a barrier to reading. Conclusion Rather than use a top-down approach to the development of training for health care practitioners and information for patients and carers, we have used data from key stakeholders to develop a patient DVD, patient leaflets to guide symptom management and a modular e-learning resource which should equip GPs to diagnose and manage CFS

Methods Two questionnaire-based surveys were applied comparing 432 primary headache and 194 LBP patients. Results In total, 84.75% of all patients reported use of CAM; with significantly more LBP patients.

Nearly all patients with previous experience with CAM currently use CAM in both conditions (93.6% in headache; 100% in LBP. However, the majority of the patients had no previous experience. Conclusion Understanding motivations for CAM treatment is important, because attitudes derive from wishes for non-pharmacological treatment, to be more involved in treatment and avoid side effects. Despite higher age and more permanent pain in LBP, both groups show high use of CAM with only little specific difference in preferred methods and attitudes towards CAM use. This may reflect deficits and unfulfilled goals in conventional treatment. Maybe CAM can decrease the gap between patients' expectations about pain therapy and treatment reality, considering that both conditions are often chronic diseases, causing high burdens for daily life.

The selection criteria were: UCLBP; 18-65years; understanding of the Spanish language; absence of parallel educational interventions; absence of red flags; not showing cognitive impairment or fibromyalgia; absence of thoracic-lumbar surgery, and exercise tolerance. The control group received the usual Back Schools program. The experimental group also received a written document for home reading, plus the subsequent sharing, clarifying doubts, and beliefs and goals restructuring during the development of the sessions. Both interventions lasted about 280minutes (7 sessions×40min). The main variables included FA and CAT. Pain and disability were also assessed. Some «demographic» and «related disorder» variables were considered in the analysis. Statistically significant differences were observed in the experimental group versus control, in the variation of FA -14 (-25.5; 0) vs -4 (-13; 0) (P=.009), and CAT -9 (-18; -4) vs -4,5 (-8.25; 0) (P=.000), were observed. Also differences in disability (P=.046), but not in pain (P=.280). These results should be considered in light of possible limits imposed by the study. Its pragmatic nature would allow a potential transfer to usual care. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    This study investigated the views of primary care patients in receipt of Medicare-funded team care for chronic disease management (CDM) in Australia. A qualitative study using a repeat in-depth interview design. Twenty-three patients (17 female), aged 32-89, were recruited over a six-month period from two purposively selected general practices: one urban and one regional practice in Queensland, Australia. Semi-structured interviews were conducted with participants 6 months apart. An interview guide was used to ensure consistency of topics explored. Interviews were recorded and transcribed, and a thematic analysis was conducted. Patients in this study viewed the combined contributions of a GP and other health professionals in team care as thorough and reassuring. In this case of Medicare-funded team care, patients also saw obligations within the structured care routine which cultivated a personal ethics of CDM. This was further influenced by how patients viewed their role in the health-care relationship. Aside from personal obligations, Medicare funding got patients engaged in team care by providing financial incentives. Indeed, this was a defining factor in seeing allied health professionals. However, team care was also preferential due to patients' valuations of costs and benefits. Patients are likely to engage with a structured team care approach to CDM if there is a sense of personal obligation and sufficient financial incentive. The level of engagement in team care is likely to be optimized if patient expectations and preferences are considered in decisions. © 2013 Blackwell Publishing Ltd.

    A sustained epidemic of cardiovascular disease and related risk factors is a global phenomenon contributing significantly to premature deaths and costly morbidity. Preventative strategies across the full continuum of life, from a population to individual perspective, are not optimally applied. This paper describes a simple and adaptable 'traffic-light' system we have developed to systematically perform individual risk and need delineation in order to 'titrate' the intensity and frequency of healthcare intervention in a cost-effective manner. The GARDIAN (Green Amber Red Delineation of Risk and Need) system is an individual assessment of risk and need that modulates the frequency and intensity of future healthcare intervention. Individual assessment of risk and need for ongoing intervention and support is determined with reference to three domains: (1) clinical stability, (2) gold-standard management, and (3) a broader, holistic assessment of individual circumstance. This can be applied from a primary prevention, secondary prevention, or chronic disease management perspective. Our experience with applying and validating GARDIAN to titrate healthcare resources according to need has been extensive to date, with >5000 individuals profiled in a host of clinical settings. A series of clinical randomized trials will determine the impact of the GARDIAN system on important indices of healthcare utilization and health status. The GARDIAN model to delineating risk and need for varied intensity of management shows strong potential to cost effectively improve health outcomes for both individuals at risk of heart disease and those with established heart disease.

    Full Text Available Abstract Background Chronic kidney disease (CKD is a relatively newly recognised but common long-term condition affecting 5 to 10% of the population. Effective management of CKD, with emphasis on strict blood pressure (BP control, reduces cardiovascular risk and slows the progression of CKD. There is currently an unprecedented rise in referral to specialist renal services, which are often located in tertiary centres, inconvenient for patients, and wasteful of resources. National and international CKD guidelines include quality targets for primary care. However, there have been no rigorous evaluations of strategies to implement these guidelines. This study aims to test whether quality improvement interventions improve primary care management of elevated BP in CKD, reduce cardiovascular risk, and slow renal disease progression Design Cluster randomised controlled trial (CRT Methods This three-armed CRT compares two well-established quality improvement interventions with usual practice. The two interventions comprise: provision of clinical practice guidelines with prompts and audit-based education. The study population will be all individuals with CKD from general practices in eight localities across England. Randomisation will take place at the level of the general practices. The intended sample (three arms of 25 practices powers the study to detect a 3 mmHg difference in systolic BP between the different quality improvement interventions. An additional 10 practices per arm will receive a questionnaire to measure any change in confidence in managing CKD. Follow up will take place over two years. Outcomes will be measured using anonymised routinely collected data extracted from practice computer systems. Our primary outcome measure will be reduction of systolic BP in people with CKD and hypertension at two years. Secondary outcomes will include biomedical outcomes and markers of quality, including practitioner confidence in managing CKD. A small

    Physical activity is an important aspect in the treatment of patients with chronic obstructive pulmonary disease or type-2 diabetes. A monitoring and feedback tool combined with guidance by a primary care provider might be a successful method to enhance the level of physical activity in these patients. As a prerequisite for useful technology, it is important to involve the end-users in the design process from an early stage. The aim of this study was to investigate the user requirements for a tool to stimulate physical activity, embedded in primary care practice. The leading principle of this tool is to change behavior by self-monitoring, goal-setting, and feedback. The research team collected qualitative data among 15 patients, 16 care professionals, and several experts. A prototype was developed in three stages. In stage 1, the literature was searched to identify end-users and context. In stage 2, the literature, experts and patient representatives were consulted to set up a use case with the general idea of the innovation. In stage 3, individual interviews and focus groups were held to identify the end-user requirements. Based on these requirements a prototype was built by the engineering team. The development process has led to a tool that generally meets the requirements of the end-users. A tri-axial activity sensor, worn on the hip, is connected by Bluetooth to a smartphone. In an app, quantitative feedback is given about the amount of activity and goals reached by means of graphical visualization, and an image shows a sun when the goal is reached. Overviews about activity per half an hour, per day, week, and month are provided. In the menu of the app and on a secured website, patients can enter information in individual sessions or read feedback messages generated by the system. The practice nurse can see the results of all patients on a secure webpage and can then discuss the results and set personalized goals in consultation with the patient. This study

    Up to half of all smokers develop clinically significant chronic obstructive pulmonary disease (COPD). Gaps exist in the implementation and uptake of evidence-based guidelines for managing COPD in primary care. We describe the methodology of a cluster randomised controlled trial (cRCT) evaluating the efficacy and cost-effectiveness of an interdisciplinary model of care aimed at reducing the burden of smoking and COPD in Australian primary care settings. A cRCT is being undertaken to evaluate an interdisciplinary model of care (RADICALS - Review of Airway Dysfunction and Interdisciplinary Community-based care of Adult Long-term Smokers). General practice clinics across Melbourne, Australia, are identified and randomised to the intervention group (RADICALS) or usual care. Patients who are current or ex-smokers, of at least 10 pack years, including those with an existing diagnosis of COPD, are being recruited to identify 280 participants with a spirometry-confirmed diagnosis of COPD. Handheld lung function devices are being used to facilitate case-finding. RADICALS includes individualised smoking cessation support, home-based pulmonary rehabilitation and home medicines review. Patients at control group sites receive usual care and Quitline referral, as appropriate. Follow-ups occur at 6 and 12 months from baseline to assess changes in quality of life, abstinence rates, health resource utilisation, symptom severity and lung function. The primary outcome is change in St George's Respiratory Questionnaire score of patients with COPD at 6 months from baseline. This project has been approved by the Monash University Human Research Ethics Committee and La Trobe University Human Ethics Committee (CF14/1018 - 2014000433). Results of the study will be disseminated in peer-reviewed journals and research conferences. If the intervention is successful, the RADICALS programme could potentially be integrated into general practices across Australia and sustained over time. ACTRN

    Thiamethoxam is a neonicotinoid insecticide used widely in agriculture to control a broad spectrum of chewing and sucking insect pests. Recent detection of thiamethoxam in surface waters has raised interest in characterizing the potential impacts of this insecticide to aquatic organisms. We report the results of toxicity testing (acute and chronic) conducted under good laboratory practices for more than 30 freshwater species (insects, molluscs, crustaceans, algae, macrophytes, and fish) and 4 marine species (an alga, a mollusc, a crustacean, and a fish). As would be anticipated for a neonicotinoid, aquatic primary producers and fish were the least sensitive organisms tested, with acute median lethal and effect concentrations (LC50/EC50) observed to be ≥80 mg/L in all cases, which far exceeds surface water exposure concentrations. Tested molluscs, worms, and rotifers were similarly insensitive (EC50 ≥ 100 mg/L), except for Lumbriculus sp., with an EC50 of 7.7 mg/L. In general, insects were the most sensitive group in the study, with most acute EC50 values insects (acute EC50 insects (EC50 > 5.5 mg/L). The most sensitive chronic response was for Chironomus riparius, with a 30-d no-observed-effect concentration (NOEC; emergence) of 0.01 mg/L. Observed toxicity to the tested marine organisms was comparable to that of freshwater species. We used the reported data to construct species sensitivity distributions for thiamethoxam, to calculate 5% hazard concentrations (HC5s) for acute data (freshwater invertebrates), and compared these with measured concentrations from relevant North American surface waters. Overall, based on acute toxicity endpoints, the potential acute risk to freshwater organisms was found to be minimal (likelihood of exceeding HC5s < 1%).

    Full Text Available Chronic intestinal pseudo-obstruction is an uncommon syndrome characterized by relapsing episodes suggesting intestinal obstruction during which no mechanical causes are identified to account for symptoms. Etiologic factors may be manifold. Among them a number of neurologic conditions, gastrointestinal smooth muscle myopathies, endocrino-metabolic and autoimmune diseases, and the use of selected drugs stand out. We report a case of chronic intestinal pseudo-obstruction originating in a sporadic, primary intestinal myopathy that corresponds to no type thus far described. A histological study of the intestinal wall showed disrupted muscle bundles and the presence of interstitial edema. Myocytes had severe degenerative changes, and no alterations were seen in submucosal and myenteric plexus neurons. The activity of enzyme complexes in the mitochondrial respiratory chain, and of thymidine phosphorylase was normal. No mitochondrial DNA changes were seen.La pseudo-obstrucción intestinal crónica es un síndrome infrecuente caracterizado por episodios recidivantes, sugestivos de obstrucción intestinal, durante los cuales no se detectan causas mecánicas que justifiquen la sintomatología. Los factores etiológicos pueden ser múltiples.

    Self-management support for chronic obstructive pulmonary disease (COPD) patients is recommended by UK national guidelines, but extent of implementation is unknown. We aimed to describe self-management behaviour and support among COPD patients and explore behaviour associated with having a self-management plan. We undertook cross-sectional analysis of self-reported data from diagnosed COPD patients in the Birmingham COPD Cohort study. Questionnaire items relevant to self-management behaviour, knowledge of COPD, receipt of self-management plans and advice from healthcare professionals were examined. Multiple regression models were used to identify behaviour associated with having a self-management plan. One-thousand seventy-eight participants (676 males, 62.7%, mean age 69.8 (standard deviation 9.0) years) were included. The majority reported taking medications as instructed (940, 94.0%) and receiving annual influenza vaccinations (962, 89.2%). Only 400 (40.4%) participants had self-management plans, 538 (49.9%) reported never having received advice on diet/exercise and 110 (42.7%) current smokers had been offered practical help to stop smoking in the previous year. General knowledge about COPD was moderate (mean total Bristol COPD Knowledge Questionnaire score: 31.5 (standard deviation 10.7); max score 65), corresponding to 48.5% of questions answered correctly. Having a self-management plan was positively associated with self-reported adherence to medication (odds ratio 3.10, 95% confidence interval 1.43 to 6.72), attendance at a training course (odds ratio 2.72, 95% confidence interval 1.81 to 4.12), attendance at a support group (odds ratio 6.28, 95% confidence interval 2.96 to 13.35) and better disease knowledge (mean difference 4.87, 95% confidence interval 3.16 to 6.58). Primary care healthcare professionals should ensure more widespread implementation of individualised self-management plans for all patients and improve the lifestyle advice provided. CALL FOR

    To evaluate the cost-effectiveness of the Geriatric Care Model (GCM), an integrated care model for frail older adults based on the Chronic Care Model, with that of usual care. Economic evaluation alongside a 24-month stepped-wedge cluster-randomized controlled trial. Primary care (35 practices) in two regions in the Netherlands. Community-dwelling older adults who were frail according to their primary care physicians and the Program on Research for Integrating Services for the Maintenance of Autonomy case-finding tool questionnaire (N = 1,147). The GCM consisted of the following components: a regularly scheduled in-home comprehensive geriatric assessment by a practice nurse followed by a customized care plan, management and training of practice nurses by a geriatric expert team, and coordination of care through community network meetings and multidisciplinary team consultations of individuals with complex care needs. Outcomes were measured every 6 months and included costs from a societal perspective, health-related quality of life (Medical Outcomes Study 12-item Short-Form Survey (SF-12) physical (PCS) and mental component summary (MCS) scales), functional limitations (Katz activities of daily living and instrumental activities of daily living), and quality-adjusted life years based on the EQ-5D. Multilevel regression models adjusted for time and baseline confounders showed no significant differences in costs ($356, 95% confidence interval = -$488-1,134) and outcomes between intervention and usual care phases. Cost-effectiveness acceptability curves showed that, for the SF-12 PCS and MCS, the probability of the intervention being cost-effective was 0.76 if decision-makers are willing to pay $30,000 per point improvement on the SF-12 scales (range 0-100). For all other outcomes the probability of the intervention being cost-effective was low. Because the GCM was not cost-effective compared to usual care after 24 months of follow-up, widespread implementation

    Exacerbations constitute a major cause of morbidity and mortality in patients suffering from chronic obstructive pulmonary disease (COPD). Both bacterial infections, such as those with non-typeable Haemophilus influenzae (NTHi), and exposures to diesel engine emissions are known to contribute to exacerbations in COPD patients. However, the effect of diesel exhaust (DE) exposure on the epithelial response to microbial stimulation is incompletely understood, and possible differences in the response to DE of epithelial cells from COPD patients and controls have not been studied. Primary bronchial epithelial cells (PBEC) were obtained from age-matched COPD patients (n = 7) and controls (n = 5). PBEC were cultured at the air-liquid interface (ALI) to achieve mucociliary differentiation. ALI-PBECs were apically exposed for 1 h to a stream of freshly generated whole DE or air. Exposure was followed by 3 h incubation in presence or absence of UV-inactivated NTHi before analysis of epithelial gene expression. DE alone induced an increase in markers of oxidative stress (HMOX1, 50-100-fold) and of the integrated stress response (CHOP, 1.5-2-fold and GADD34, 1.5-fold) in cells from both COPD patients and controls. Exposure of COPD cultures to DE followed by NTHi caused an additive increase in GADD34 expression (up to 3-fold). Importantly, DE caused an inhibition of the NTHi-induced expression of the antimicrobial peptide S100A7, and of the chaperone protein HSP5A/BiP. Our findings show that DE exposure of differentiated primary airway epithelial cells causes activation of the gene expression of HMOX1 and markers of integrated stress response to a similar extent in cells from COPD donors and controls. Furthermore, DE further increased the NTHi-induced expression of GADD34, indicating a possible enhancement of the integrated stress response. DE reduced the NTHi-induced expression of S100A7. These data suggest that DE exposure may cause adverse health effects in part by

    Development of mice expressing either ovine (Tg338) or cervid (TgElk) prion protein (PrP) have aided in characterization of scrapie and chronic wasting disease (CWD), respectively. Experimental inoculation of sheep with CWD prions has demonstrated the potential for interspecies transmission but, infection with CWD versus classical scrapie prions may be difficult to differentiate using validated diagnostic platforms. In this study, mouse bioassay in Tg338 and TgElk was utilized to evaluate transmission of CWD versus scrapie prions from small ruminants. Mice (≥5 per homogenate) were inoculated with brain homogenates from clinically affected sheep or goats with naturally acquired classical scrapie, white-tailed deer with naturally acquired CWD (WTD-CWD) or sheep with experimentally acquired CWD derived from elk (sheep-passaged-CWD). Survival time (time to clinical disease) and attack rates (brain accumulation of protease resistant PrP, PrPres) were determined. Inoculation with classical scrapie prions resulted in clinical disease and 100 % attack rates in Tg338, but no clinical disease at endpoint (>300 days post-inoculation, p.i.) and low attack rates (6.8 %) in TgElk. Inoculation with WTD-CWD prions yielded no clinical disease or brain PrPres accumulation in Tg338 at endpoint (>500 days p.i.), but rapid onset of clinical disease (~121 days p.i.) and 100 % attack rate in TgElk. Sheep-passaged-CWD resulted in transmission to both mouse lines with 100 % attack rates at endpoint in Tg338 and an attack rate of ~73 % in TgElk with some culled due to clinical disease. These primary transmission observations demonstrate the potential of bioassay in Tg338 and TgElk to help differentiate possible infection with CWD versus classical scrapie prions in sheep and goats.

    Full Text Available Background: Respiratory diseases, namely asthma and chronic obstructive pulmonary disease (COPD, account for one-fourth of the patients at the primary health-care (PHC facilities in Pakistan. Standard care practices to manage these diseases are necessary to reduce the morbidity and mortality rate associated with non-communicable diseases in developing countries. Objective: To develop and measure the effectiveness of operational guidelines and implementation materials, with sound scientific evidence, for expanding lung health care, especially asthma and COPD through PHC facilities already strengthened for tuberculosis (TB care in Pakistan. Design: A cluster randomized controlled trial with two arms (intervention and control, with qualitative and costing study components, is being conducted in 34 clusters; 17 clusters per arm (428 asthma and 306 COPD patients, in three districts in Pakistan from October 2014 to December 2016. The intervention consists of enhanced case management of asthma and COPD patients through strengthening of PHC facilities. The main outcomes to be measured are asthma and COPD control among the registered cases at 6 months. Cluster- and individual-level analyses will be done according to intention to treat. Residual confounding will be addressed by multivariable logistic and linear regression models for asthma and COPD control, respectively. The trial is registered with ISRCTN registry (ISRCTN 17409338. Conclusions: Currently, only about 20% of the estimated prevalent asthma and COPD cases are being identified and reported through the respective PHC network. Lung health care and prevention has not been effectively integrated into the core PHC package, although a very well-functioning TB program exists at the PHC level. Inclusion of these diseases in the already existent TB program is expected to increase detection rates and care for asthma and COPD.

    To develop and evaluate a clinical decision support system (CDSS) named Assessment and Treatment in Healthcare: Evidenced-Based Automation (ATHENA)-Opioid Therapy, which encourages safe and effective use of opioid therapy for chronic, noncancer pain. CDSS development and iterative evaluation using the analysis, design, development, implementation, and evaluation process including simulation-based and in-clinic assessments of usability for providers followed by targeted system revisions. Volunteers provided detailed feedback to guide improvements in the graphical user interface, and content and design changes to increase clinical usefulness, understandability, clinical workflow fit, and ease of completing guideline recommended practices. Revisions based on feedback increased CDSS usability ratings over time. Practice concerns outside the scope of the CDSS were also identified. Usability testing optimized the CDSS to better address barriers such as lack of provider education, confusion in dosing calculations and titration schedules, access to relevant patient information, provider discontinuity, documentation, and access to validated assessment tools. It also highlighted barriers to good clinical practice that are difficult to address with CDSS technology in its current conceptualization. For example, clinicians indicated that constraints on time and competing priorities in primary care, discomfort in patient-provider communications, and lack of evidence to guide opioid prescribing decisions impeded their ability to provide effective, guideline-adherent pain management. Iterative testing was essential for designing a highly usable and acceptable CDSS; however, identified barriers may limit the impact of the ATHENA-Opioid Therapy system and other CDSS on clinical practices and outcomes unless CDSS are paired with parallel initiatives to address these issues.

    To explore the regional brain activities in patients with chronic primary insomnia (PCPIs) and their sex differences. Forty-two PCPIs (27 females, 15 males) and 42 good sleepers (GSs; 24 females, 18 males) were recruited. Six PCPIs (3 males, 3 females) were scanned twice by MRI to examine the test-retest reliability. Amplitude of low frequency fluctuation (ALFF) method was used to assess the local brain features. The mean signal values of the different ALFF areas were analyzed with a receiver operating characteristic (ROC) curve. Simple linear regression analysis was performed to investigate the relationships between clinical features and different brain areas. Both female and male PCPIs showed higher ALFF in the temporal lobe and occipital lobe, especially in female PCPIs. Female PCPIs had lower ALFF in the bilateral cerebellum posterior lobe, left dorsolateral prefrontal cortex, and bilateral limbic lobe; however, male PCPIs showed lower ALFF in the left occipital gyrus. The mean signal value of the cerebellum in female PCPIs showed negative correlations with negative emotions. Compared with male PCPIs, female PCPIs showed higher ALFF in the bilateral middle temporal gyrus and lower ALFF in the left limbic lobe. The different areas showed high test-retest stability (Clusters of contiguous volumes ≥ 1080 mm(3) with an intraclass correlation coefficient ≥ 0.80) and high degree of sensitivity and specificity. Female PCPIs showed more regional brain differences with higher and lower ALFF responses than male PCPIs. However, they shared analogous excessive hyperarousal mechanism and wide variations in aberrant brain areas. © 2016 American Academy of Sleep Medicine.

    Communities of practice are based on the idea that learning involves a group of people exchanging experiences and knowledge. The e-MPODERA project aims to assess the effectiveness of a virtual community of practice aimed at improving primary healthcare professional attitudes to the empowerment of patients with chronic diseases. This paper describes the protocol for a cluster randomized controlled trial. We will randomly assign 18 primary-care practices per participating region of Spain (Catalonia, Madrid and Canary Islands) to a virtual community of practice or to usual training. The primary-care practice will be the randomization unit and the primary healthcare professional will be the unit of analysis. We will need a sample of 270 primary healthcare professionals (general practitioners and nurses) and 1382 patients. We will perform randomization after professionals and patients are selected. We will ask the intervention group to participate for 12 months in a virtual community of practice based on a web 2.0 platform. We will measure the primary outcome using the Patient-Provider Orientation Scale questionnaire administered at baseline and after 12 months. Secondary outcomes will be the sociodemographic characteristics of health professionals, sociodemographic and clinical characteristics of patients, the Patient Activation Measure questionnaire for patient activation and outcomes regarding use of the virtual community of practice. We will calculate a linear mixed-effects regression to estimate the effect of participating in the virtual community of practice. This cluster randomized controlled trial will show whether a virtual intervention for primary healthcare professionals improves attitudes to the empowerment of patients with chronic diseases.

    During HIV-1 infection the B-cell compartment undergoes profound changes towards terminal differentiation, which are only partially restored by antiretroviral therapy (cART). To investigate the impact of infection as early as during primary HIV-1 infection (PHI) we assessed distribution of B-cell subsets in 19 PHI and 25 chronic HIV-1-infected (CHI) individuals before and during 48 weeks of cART as compared to healthy controls (n = 23). We also analysed Immunoglobulin-expression of memory B-cell subsets to identify alterations in Immunoglobulin-maturation. Determination of B-cell subsets at baseline showed that total and Naive B-cells were decreased whereas Activated Memory (AM), Tissue-like Memory (TLM) B-cells and Plasma cells were increased in both PHI and CHI patients. After 4 weeks of cART total B-cells increased, while AM, TLM B-cells and Plasma cells decreased, although without reaching normal levels in either group of individuals. This trend was maintained until week 48, though only total B-cells normalized in both PHI and CHI. Resting Memory (RM) B-cells were preserved since baseline. This subset remained stable in CHI, while was expanded by an early initiation of cART during PHI.

    Computerized chronic disease management systems (CDMSs), when aligned with clinical practice guidelines, have the potential to effectively impact diabetes care. The objective was to measure the difference between optimal diabetes care and actual diabetes care before and after the introduction of a computerized CDMS. This 1-year, prospective, observational, pre/post study evaluated the use of a CDMS with a diabetes patient registry and tracker in family practices using patient enrolment models. Aggregate practice-level data from all rostered diabetes patients were analyzed. The primary outcome measure was the change in proportion of patients with up-to-date "ABC" monitoring frequency (i.e., hemoglobin A1c, blood pressure, and cholesterol). Changes in the frequency of other practice care and treatment elements (e.g., retinopathy screening) were also determined. Usability and satisfaction with the CDMS were measured. Nine sites, 38 health care providers, and 2,320 diabetes patients were included. The proportion of patients with up-to-date ABC (12%), hemoglobin A1c (45%), and cholesterol (38%) monitoring did not change over the duration of the study. The proportion of patients with up-to-date blood pressure monitoring improved, from 16% to 20%. Data on foot examinations, retinopathy screening, use of angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, and documentation of self-management goals were not available or not up to date at baseline for 98% of patients. By the end of the study, attitudes of health care providers were more negative on the Training, Usefulness, Daily Practice, and Support from the Service Provider domains of the CDMS, but more positive on the Learning, Using, Practice Planning, CDMS, and Satisfaction domains. Few practitioners used the CDMS, so it was difficult to draw conclusions about its efficacy. Simply giving health care providers a potentially useful technology will not ensure its use. This real-world evaluation of a

    The inverse equity hypothesis asserts that new health policies initially widen inequality, then attenuate inequalities over time. Since 2004, the UK's pay-for-performance scheme for chronic disease management (CDM) in primary care general practices (the Quality and Outcomes Framework) has permitted practices to except (exclude) patients from attending annual CDM reviews, without financial penalty. Informed dissent (ID) is one component of exception rates, applied to patients who have not attended due to refusal or non-response to invitations. 'Population achievement' describes the proportion receiving care, in relation to those eligible to receive it, including excepted patients. Examination of exception reporting (including ID) and population achievement enables the equity impact of the UK pay-for-performance contract to be assessed. We conducted a longitudinal analysis of practice-level rates and of predictors of ID, overall exceptions and population achievement for CDM to examine whether the inverse equity hypothesis holds true. We carried out a retrospective, longitudinal study using routine primary care data, analysed by multilevel logistic regression. Data were extracted from 793 practices (83% of Scottish general practices) serving 4.4 million patients across Scotland from 2010/2011 to 2012/2013, for 29 CDM indicators covering 11 incentivised diseases. This provided 68,991 observations, representing a total of 15 million opportunities for exception reporting. Across all observations, the median overall exception reporting rate was 7.0% (7.04% in 2010-2011; 7.02% in 2011-2012 and 6.92% in 2012-2013). The median non-attendance rate due to ID was 0.9% (0.76% in 2010-2011; 0.88% in 2011-2012 and 0.96% in 2012-2013). Median population achievement was 83.5% (83.51% in 2010-2011; 83.41% in 2011-2012 and 83.63% in 2012-2013). The odds of ID reporting in 2012/2013 were 16.0% greater than in 2010/2011 (p rural practices reported lower levels of non-attendance due to

    To analyse the correlates between the quality of life and chronic diseases and socio-demographic characteristics of patients in family medicine with a special emphasis on depression, panic syndrome, other anxiety syndrome and alcoholism. In a longitudinal study, the data set of 516 family practice attendees recruited from 60 family practices was analysed. Depression, panic syndrome, other anxiety syndrome and alcoholism were diagnosed using appropriate diagnostic interviews. Quality of life was assessed using the SF-12 questionnaire, measuring a mental health score and a physical health score. Data about the number of chronic somatic diseases were obtained from the patients' medical records. Physical health score was negatively associated with higher age (β = -0.25, p chronic somatic diseases (β = -0.10, p chronic somatic diseases as they are associated with poorer quality of life.

    Our aim was to analyze both metabolic control and chronic complications of type 2 diabetes mellitus (T2D) patients regularly attended in primary care during a 3 years of follow-up in the Community of Madrid (Spain). From 2007 to 2010 we prospectively included 3268 patients with T2D attended by 153 primary care physicians from 51 family health centers. An prospective cohort study with annual evaluation over 3 years to the same population was performed. We measured the goals of control in diabetic patients and the incidence of chronic complications of diabetes during the study period. A significant decrease in serum glucose levels (143±42mg/dl vs 137±43mg/dl, p1.2% vs 7.02±1.2%, p191.4±38mg/dl vs 181.5±36mg/dl, p114.7±31mg/dl vs 105.5±30mg/dl, p144.5±93mg/dl vs 138±84mg/dl, p14mg/dl vs 49.9±16mg/dl, pdiabetic complications throughout the study period was low, with a incidence of coronary heart disease of 6.2%, peripheral arterial disease 3%, ischemic stroke 2.8%, diabetic foot 11.2%, nephropathy 5.9%, retinopathy 4.5%, and neuropathy 3%. Metabolic control in T2D patients attended in primary care in the Community of Madrid throughout 3 years is adequate and is accompanied by low percent of chronic diabetic complications during this period of follow-up.

    Full Text Available Background: This study investigated the effects of integrating primary chronic care with current healthcare activities in two local government health units (LGHU of the Philippines on knowledge and skills of the LGHU staff and clinical outcomes for people with diabetes. Design: Integration was accomplished through health service reorganization, (redistribution of chronic care tasks, and training of LGHU staff. Levels of the staff's pre- and post-training diabetes knowledge and of their self-assessment of diabetes care-related skills were measured. Primary diabetes care with emphasis on self-care development was provided to a cohort of people with diabetes. Glycosylated hemoglobin (HbA1c and obesity measures were collected prior to and one year after full project implementation. Results: The training workshop improved diabetes knowledge (p<0.001 and self-assessed skills (p<0.001 of the LGHU staff. Significant reductions in HbA1c (p<0.001, waist–hip ratio (p<0.001 and waist circumference (p=0.011 of the cohort were noted. Although the reduction in HbA1c was somewhat greater among those whose community-based care providers showed improvement in knowledge and self-assessed skills, the difference was not statistically significant. Conclusions: Primary care for chronic conditions such as diabetes may be integrated with other healthcare activities in health services of low-to-middle-income countries such as the Philippines, utilizing pre-existing human resources for health, and may improve clinical endpoints.

    2016-03-01

    Full Text Available Background: Trabeculectomy is a surgical therapy for glaucoma to preserve visual function by lowering intraocular pressure (IOP. In some studies, the success of trabeculectomy in lowering IOP is greater than medication. Success is defined by IOP <21 mmHg, with or without glaucoma medication. Primary glaucoma based on the mechanism of aquous humor outflow is divided into primary open-angle glaucoma (POAG and primary angle-closure glaucoma (PACG. This study aimed to know the success rate of trabeculectomy in POAG and PACG. Methods: This study was a descriptive study conducted at Cicendo Eye Hospital using medical record of POAG and PACG patients who underwent trabeculectomy surgery on January–December 2013 with minimal one month follow-up. Data collection was conducted during September 2014. Data processed in this study were 100 eyes from 76 patients with diagnosis POAG and PACG. Results: The success rate for trabeculectomy in POAG was 79% and PACG was 86%, failure (IOP ≥ 21 mmHg 21% in POAG, and 14% in PACG for period 2013 at Cicendo Eye Hospital. Conclusions: The success rate of trabeculectomy at Cicendo Eye Hospital is good in one month, with or without glaucoma medication after surgery.

    Chronic airway diseases pose a big challenge to health systems in most developing countries, particularly in Sub-Saharan Africa. A diagnosis for people with chronic or persistent cough is usually delayed because of individual and health system barriers. However, delayed diagnosis and treatment facilitates further transmission, severity of disease with complications and mortality. The objective of this study is to assess the cost-effectiveness of the practical approach to lung health strategy, a patient-centred approach for diagnosis and treatment of common respiratory illnesses in primary healthcare settings, as a means of strengthening health systems to improve the quality of management of respiratory diseases. Economic evaluation nested in a cluster randomised controlled trial with three arms will be performed. Measures of effectiveness and costs for all arms of the study will be obtained from the cluster randomised controlled clinical trial. The main outcome measures are a combined rate of major respiratory diseases milestones and process indicators extracted from the practical approach to lung health strategy. For analysis, descriptive as well as regression techniques will be used. A cost-effectiveness analysis will be performed according to intention-to-treat principle and from a societal perspective. Cost-effectiveness ratios will be calculated using bootstrapping techniques. We hope to demonstrate the cost-effectiveness of the practical approach to lung health and informal healthcare providers, see an improvement in patients' quality of life, achieve a reduction in the duration and occurrence of episodes and the chronicity of respiratory diseases, and are able to report a decrease in the social cost. If the practical approach to lung health and informal healthcare provider's interventions are cost-effective, they could be scaled up to all primary healthcare centres. PACTR: PACTR201411000910192.

    Self-care and management of therapeutic regime (drugs adherence, preventive behaviours and development of healthy life-styles) are key components for managing chronic diseases. Nursing has standardized languages which describe many of these situations, such as the diagnosis "Ineffective Self Health Management" (ISHM) or many of the Nursing Outcomes Classification (NOC) indicators. The aims of this study were to determine the interobserver reliability of a NOC-based instrument for assessment and aid in diagnosis of the ISHM in patients with chronic conditions in Primary Health Care, to determine its diagnostic validity and to describe the prevalence of patients with this problem. Cross-sectional validation study developed in the provinces of Málaga, Cádiz and Almería from 2006 to 2009. Each patient was assessed by 3 independent observers: the first two observers evaluated scoring of the NOC indicators and the third one acted as the "gold-standard". Two hundred and twenty-eight patients were included, 37.7% of them with more than one chronic condition. NOC indicators showed a high interobserver reliability (ICC>0,70) and a consistency (Cronbach's alpha: 0.81). With a cut-point of 10.5, sensitivity was 61% and specificity 85%, and the area under the curve was 0.81 (CI95%: 0.77 to 0.85). The prevalence of patients with ISHM was 36% (CI 95%: 34 to 40). The use of NOC indicators allows evaluation of management of the therapeutic regime in people with chronic conditions with a satisfactory validity and it provides new approaches for dealing with this problem.

    Low back pain is the highest reported musculoskeletal problem worldwide. Up to 90 % of patients with low back pain have no clear explanation for the source and origin of their pain. These individuals commonly receive a diagnosis of non-specific low back pain. Patient education is a way to provide information and advice aimed at changing patients' cognition and knowledge about their chronic state through the reduction of fear of anticipatory outcomes and the resumption of normal activities. Information technology and the expedited communication processes associated with this technology can be used to deliver health care information to patients. Hence, this technology and its ability to deliver life-changing information has grown as a powerful and alternative health promotion tool. Several studies have demonstrated that websites can change and improve chronic patients' knowledge and have a positive impact on patients' attitudes and behaviors. The aim of this project is to identify chronic low back pain patients' beliefs about the origin and meaning of pain to develop a web-based educational tool using different educational formats and gamification techniques. This study has a mixed-method sequential exploratory design. The participants are chronic low back pain patients between 18-65 years of age who are attending a primary care setting. For the qualitative phase, subjects will be contacted by their family physician and invited to participate in a personal semi-structured interview. The quantitative phase will be a randomized controlled trial. Subjects will be randomly allocated using a simple random sample technique. The intervention group will be provided access to the web site where they will find information related to their chronic low back pain. This information will be provided in different formats. All of this material will be based on the information obtained in the qualitative phase. The control group will follow conventional treatment provided by their

    The control of chronic pain is a major challenge for patients and health care professionals. To culturally adapt the Nursing Outcomes Classification outcome "Pain control" (PC) to the Spanish health care setting and to analyze its psychometric properties and sensitivity to change. A study of three stages was designed: (1) Translation and cultural adaptation by translation-back-translation method, (2) content validation by a group of experts, and (3) observational-longitudinal study in patients with chronic pain. Patient sampling was nonprobabilistic, and participants completed forms and questionnaires and responded to a question on pain. Statistical analysis included descriptive analysis, content validity index (for global PC and each indicator), principal component analysis, Spearman's test, Cronbach's α, Cohen's κ coefficient, and Wilcoxon range test. The new Spanish version of "Pain control" was semantically equivalent to the original, with a mean content validity index of 0.96. The clinical study included 88 patients with long-term pain, and the mean (standard deviation) interval between assessments (baseline and final) was 29.33 (8.05) days. Thirteen indicators were organized into two components. There was divergent but not convergent validity with the Change Pain Scale and Brief Pain Inventory. Between-observer agreement was κ = 0.48 and internal consistency was α = 0.85. No differences were found between mean baseline and final scores. The Spanish version of "Pain control," culturally adapted and structured in two components (13 indicators), is useful to assess and monitor pain control in patients with chronic pain.

    The antiplatelet therapy in the primary prevention of cardiovascular disease in patients with chronic obstructive pulmonary disease (APPLE COPD-ICON2) trial is a prospective 2×2 factorial, double-blinded proof-of-concept randomised controlled trial targeting patients with chronic obstructive pulmonary disease (COPD) at high risk of cardiovascular disease. The primary goal of this trial is to investigate if treatment with antiplatelet therapy will produce the required response in platelet function measured using the Multiplate test in patients with COPD. Patients with COPD are screened for eligibility using inclusion and exclusion criteria. Eligible patients are randomised and allocated into one of four groups to receive aspirin plus placebo, ticagrelor plus placebo, aspirin plus ticagrelor or placebo only. Markers of systemic inflammation, platelet reactivity, arterial stiffness, carotid intima-media thickness (CIMT), lung function and quality of life questionnaires are assessed. The primary outcome consists of inhibition (binary response) of aspirin and ADP-induced platelet function at 6 months. Secondary outcomes include changes in inflammatory markers, CIMT, non-invasive measures of vascular stiffness, quality of life using questionnaires (EuroQol-five dimensions-five levels of perceived problems (EQ5D-5L), St. George's COPD questionnaire) and to record occurrence of repeat hospitalisation, angina, myocardial infarction or death from baseline to 6 months. Safety outcomes will be rates of major and minor bleeding, forced expiratory volume in 1 s, forced vital capacity and Medical Research Council dyspnoea scale. The study was approved by the North East-Tyne and Wear South Research Ethics Committee (15/NE/0155). Findings of the study will be presented in scientific sessions and published in peer-reviewed journals.

    Electronic medical records (EMRs) used in primary care contain a breadth of data that can be used in public health research. Patient data from EMRs could be linked with other data sources, such as a postal code linkage with Census data, to obtain additional information on environmental determinants of health. While promising, successful linkages between primary care EMRs with geographic measures is limited due to ethics review board concerns. This study tested the feasibility of extracting full postal code from primary care EMRs and linking this with area-level measures of the environment to demonstrate how such a linkage could be used to examine the determinants of disease. The association between obesity and area-level deprivation was used as an example to illustrate inequalities of obesity in adults. The analysis included EMRs of 7153 patients aged 20 years and older who visited a single, primary care site in 2011. Extracted patient information included demographics (date of birth, sex, postal code) and weight status (height, weight). Information extraction and management procedures were designed to mitigate the risk of individual re-identification when extracting full postal code from source EMRs. Based on patients' postal codes, area-based deprivation indexes were created using the smallest area unit used in Canadian censuses. Descriptive statistics and socioeconomic disparity summary measures of linked census and adult patients were calculated. The data extraction of full postal code met technological requirements for rendering health information extracted from local EMRs into anonymized data. The prevalence of obesity was 31.6 %. There was variation of obesity between deprivation quintiles; adults in the most deprived areas were 35 % more likely to be obese compared with adults in the least deprived areas (Chi-Square = 20.24(1), p primary health care interventions and services.

    In many low-income countries, care for patients with non-communicable diseases (NCDs) and mental health conditions is provided by nurses. The benefits of nurse substitution and supplementation in NCD care in high-income settings are well recognised, but evidence from low- and middle-income countries is limited. Primary Care 101 (PC101) is a programme designed to support and expand nurses' role in NCD care, comprising educational outreach to nurses and a clinical management tool with enhanced prescribing provisions. We evaluated the effect of the programme on primary care nurses' capacity to manage NCDs. In a cluster randomised controlled trial design, 38 public sector primary care clinics in the Western Cape Province, South Africa, were randomised. Nurses in the intervention clinics were trained to use the PC101 management tool during educational outreach sessions delivered by health department trainers and were authorised to prescribe an expanded range of drugs for several NCDs. Control clinics continued use of the Practical Approach to Lung Health and HIV/AIDS in South Africa (PALSA PLUS) management tool and usual training. Patients attending these clinics with one or more of hypertension (3,227), diabetes (1,842), chronic respiratory disease (1,157) or who screened positive for depression (2,466), totalling 4,393 patients, were enrolled between 28 March 2011 and 10 November 2011. Primary outcomes were treatment intensification in the hypertension, diabetes, and chronic respiratory disease cohorts, defined as the proportion of patients in whom treatment was escalated during follow-up over 14 mo, and case detection in the depression cohort. Primary outcome data were analysed for 2,110 (97%) intervention and 2,170 (97%) control group patients. Treatment intensification rates in intervention clinics were not superior to those in the control clinics (hypertension: 44% in the intervention group versus 40% in the control group, risk ratio [RR] 1.08 [95% CI 0.94 to 1

    IN BRIEF Cost-effective innovations to improve health and health care in patients with complex chronic diseases are urgently needed. Mobile health (mHealth) remote monitoring applications (apps) are a promising technology to meet this need. This article reports on a study evaluating patients' use of a tablet device with an mHealth app and a cellular-enabled glucose meter that automatically uploaded blood glucose values to the app. Improvements were observed across all three components of the Patient Protection and Affordable Care Act's "triple aim." Self-rated wellness and numerous quality-of-care metrics improved, billed charges and paid claims decreased, but no changes in clinical endpoints were observed.

    Full Text Available Abstract Background Fatigue is common and has been shown to result in high economic costs to society. The aim of this study is to compare the cost-effectiveness of two active therapies, graded-exercise (GET and counselling (COUN with usual care plus a self-help booklet (BUC for people presenting with chronic fatigue. Methods A randomised controlled trial was conducted with participants consulting for fatigue of over three months’ duration recruited from 31 general practices in South East England and allocated to one of three arms. Outcomes and use of services were assessed at 6-month follow-up. The main outcome measure used in the economic evaluation was clinically significant improvements in fatigue, measured using the Chalder fatigue scale. Cost-effectiveness was assessed using the net-benefit approach and cost-effectiveness acceptability curves. Results Full economic and outcome data at six months were available for 163 participants; GET = 51, COUN = 58 and BUC = 54. Those receiving the active therapies (GET and COUN had more contacts with care professionals and therefore higher costs, these differences being statistically significant. COUN was more expensive and less effective than the other two therapies. The incremental cost-effectiveness ratio of GET compared to BUC was equal to £987 per unit of clinically significant improvement. However, there was much uncertainty around this result. Conclusion This study does not provide a clear recommendation about which therapeutic option to adopt, based on efficiency, for patients with chronic fatigue. It suggests that COUN is not cost-effective, but it is unclear whether GET represents value for money compared to BUC. Clinical Trial Registration nu
