Relationship of peer specialists to mental health outcomes in South Florida

Background

In recent years the use of peer specialists in the delivery of mental health of care across the US has increased. Although data on the benefits of using peer specialists is limited and/or equivocal, states are making policy and funding decisions to support the expansion of peer specialist services. This data is even more limited in the state of Florida where no studies were found to document the effect of peer specialists on mental health care outcomes. The purpose of this study was to assess whether local decisions to use peer specialists can be supported through the measurement of outcomes of service utilization and mental health functioning when peer specialists are involved in the treatment of individuals living with serious mental illness.

Methods

The study was conducted using service data collected by South Florida Behavioral Health Network (SFBHN). SFBHN is the Managing Entity for publicly funded mental health and substance abuse services in Miami-Dade and Monroe Counties in Florida. We compared mental health outcomes and service utilization between individuals who received peer specialist services (n = 367) and a treatment as usual group (n = 1468) matched on gender, age and severity of diagnosis in the period July 2013 and June 2015. Multilevel models were used to evaluate the functioning outcomes between the groups. Service utilization was assessed using negative binomial regression.

Results

Individuals in the treatment group receiving peer specialist services utilized more ambulatory/lower levels of care services and had more frequent crisis stabilization unit admissions. Those in the treatment group also displayed more functional difficulties with a variety of practical activities, employment and housing and violent temper, hostility, threatening behaviors.

Conclusions

The findings of the study further support existing evidence documenting the mixed benefits of using peer services compared to treatment as usual care. Policy makers and other stakeholders are encouraged to advance mental health recovery by examining outcomes more comprehensively. Future research should include examination of the subjective benefits of peer support for recipients, understanding the impact on service utilization and a better definition of the roles, supervision and expectations of peer support programs.

Family and cultural influences on cervical cancer screening among immigrant Latinas in Miami-Dade County, USA

Cervical cancer disproportionately affects minorities, immigrants and low-income women in the USA, with disparities greatest among Latino immigrants. We examined barriers and facilitators to cervical cancer screening practices among a group of immigrant Latino women in Florida, USA. Between January and May 2013, six focus group discussions, involving 35 participants, were conducted among Hispanic women in Miami to explore their knowledge, beliefs about cervical cancer and facilitators and barriers to cervical cancer screening using a theoretical framework. The data showed that family support, especially from female relatives, was an important facilitator of screening and treatment. Women, however, reported prioritising family health over their own, and some expressed fatalistic beliefs about cancer. Major obstacles to receiving a Pap smear included fear that it might result in removal of the uterus, discomfort about being seen by a male doctor and concern that testing might stigmatise them as being sexually promiscuous or having a sexually transmitted disease. Targeted education on cancer and prevention is critically needed in this population. Efforts should focus on women of all ages since younger women often turn to older female relatives for advice.

Helicobacter pylori vacA s1a and s1b alleles from clinical isolates from different regions of Chile show a distinct geographic distribution

AIM

To establish the most common vacA alleles in Helicobacter pylori (H pylori) strains isolated from Chilean patients and its relationship with gastritis and gastroduodenal ulcers.

METHODS

Two hundred and forty five H pylori clinical isolates were obtained from 79 biopsies from Chilean infected patients suffering from gastrointestinal diseases. An average of 2-3 strains per patient was isolated and the vacA genotype was analyzed by PCR and 3% agarose electrophoresis. Some genotypes were checked by DNA sequencing.

RESULTS

The most prevalent vacA genotype in Chilean patients was s1b m1 (76%), followed by s1a m1 (21%). In contrast, the s2 m2 genotype was scarcely represented (3%). The s1b m1 genotype was found most frequently linked to gastropathies (P<0.05) rather than ulcers. Ulcers were found more commonly in male and older patients. Curiously, patients living in cities located North and far South of Santiago, the capital and largest Chilean city, carried almost exclusively strains with the s1b m1 genotype. In contrast, patients from Santiago and cities located South of Santiago carried strains with either one or both s1a m1 and s1b m1 genotypes. Regarding the s2 m2 genotype, comparison with GenBank sequences revealed that Chilean s2 sequence was identical to those of Australian, American, and Colombian strains but quite different from those of Alaska and India.

CONCLUSION

Differences in geographic distribution of the s and m vacA alleles in Chile and a relationship of s1b m1 genotype with gastritis were found. Sequence data in part support a hispanic origin for the vacA genotype. Asymmetric distribution of genotypes s1b m1 and s2 m2 recedes H Pylori strain distribution in Spain and Portugal.

[Triple therapy of short-term with azithromycin, amoxycillin and omeprazole for the eradication of Helicobacter pylori]

BACKGROUND

The high cost and complexity of therapeutic schemes for the eradication of Helicobacter pylori has stimulated the search of simpler and cheaper treatment options.

AIM

To evaluate the efficacy of 3 days of azithromycin 500 mg od, 7 days of amoxycillin 750 mg tid and omeprazole, 20 (Group A) or 40 mg (Group B) on randomization, as a treatment for Helicobacter pylori infection in patients with endoscopically diagnosed peptic ulcer.

METHODS

H. pylori status of peptic ulcer patients was pathologically confirmed by the examination of five gastric biopsies using the Giemsa stain and by rapid urease testing in two gastric biopsies. H. pylori status was reassessed not less than 28 days after completing treatment. Adverse events and compliance were evaluated.

RESULTS

Fifty four patients (29 men, 25 women, mean age 48 years) were enrolled, 28 in Group A and 27 in Group B. Per protocol the infection was cured in 58.8% of patients (30/51; 95% CI: 45-73%). On an intention to treat basis, H pylori infection was cured in 55%. Minor side effects including diarrhea and nausea were reported by 32% of patients. Ninety-five per cent of patients consumed more than 95% of prescribed medications. H. pylori was successfully eradicated in 61% of group A and 57% of group B patients (p = NS).

CONCLUSION

Short term therapy with azithromycin was poorly effective in curing H. pylori infection. The compliance was excellent. Increasing Omeprazole from 20 to 40 mg/day did not improve treatment effectiveness.
