Nurses must deliver infusions as prescribed since too slow or fast a dose could be deleterious to patients. Nurses experience challenges with infusion dose calculations, making them vulnerable to errors. The research team examined drop factor and infusion dose calculation discrepancies among nurses in southern Nigeria. Five university teaching hospitals were involved in this cross-sectional study conducted in 2019. To establish the drop factor of commonly available macro drip sets, the team randomly sourced 25 macro drip sets from the hospitals’ pharmacies. A sample of 291 nurses was selected using a proportionate random sampling technique. The team collected data using the Adult Infusion Dose Calculation Quiz and analyzed it at a 5% significance level. Twenty (80%) of the sampled macro drip sets displayed a drop factor value of 20 drops per milliliter (gtt/ml) on their packaging. When measured experimentally, 25 (100%) of the macro drip sets delivered exactly 20 gtt/ml. Only 36 (12.4%) respondents calculated macro drip infusion doses using the correct drop factor of 20 gtt/ml. Non-attendance of infusion administration training updates significantly increased the risk of error by 38% (p ≤ 0.001). In conclusion, the drop factor of macro drip sets used in southern Nigeria is 20 gtt/ml;nurses were prone to infusing patients at a lower dose than prescribed. Special training in infusion therapy might remedy this concern.

Background: Certain ovarian cancers that were previously common in postmenopausal women are now increasingly observed in women of reproductive age. The research on using β-HCG as a diagnostic biomarker for ovarian cancer in women of reproductive age is ongoing. Aim: This study assessed the level of serum β-HCG in non-pregnant women of reproductive age and determined its potential association with suspicious ovarian ultrasonography results. Methods: The study was conducted in Port Harcourt, Nigeria. This study adopted a cross-sectional design on a quota sample of 224 case notes of women aged 18 - 40 years obtained from eight diagnostic centres. A data extraction form was used for data collection. Data analysis employed descriptive statistics, Chi-square, Fisher’s exact test, and Odds Ratio at 95% confidence and 5% significance levels. Results: About 5.8% of the participants exhibited detectable levels of serum β-HCG above 5 IU/L (World Health Organization reference) at a mean concentration of 5.87 (±1.75) IU/L. About 4.0% of the participants had suspicious ovarian lesions identified through ultrasonography. Participants with elevated serum β-HCG levels above the WHO reference were 59 times more likely to have suspicious ovarian lesions (Odds ratio: 59.4, 95%CI: 12.3 - 287.8, p β-HCG level and age (p = 0.041) as well as parity (p Conclusion: Serum β-HCG levels above the WHO reference in non-pregnant women were associated with suspicious ovarian lesions. More rigorous primary research, systematic reviews, and meta-analyses are needed to confirm the findings of this study.

Adjuvant effect of a synthetic Aluminium-Magnesium Silicate on chloroquine phosphate, against Plasmodium berghei

Effect a synthetic Aluminium-Magnesium Silicate (AMS) has on chloroquine was tested. Thirty, Plasmodium berghei-infected mice, in three experimental groups (7 mg/kg, 5 mg/kg and 3 mg/kg) of 10 mice each, were treated. Two subgroups, in each experiment, were treated with chloroquine and with a chloroquine-AMS drug formulation, respectively. Five of the infected mice served as controls. Parasitaemia (%), Haemoglobin concentration (Hb), Red Blood Cells (RBC), rectal temperature and body weight were assessed. Parasitaemia of subgroups treated at 7 mg/kg were higher than that of the control. Also, at 7 mg/kg, there was mortality with chloroquine (20%) and with the chloroquine-AMS drug (80%). At 5 mg/kg and 3 mg/kg, the AMS significantly (P < 0.05) improved ability of chloroquine to reduce plamodial parasitaemia, from 2.46 ± 0.21 to 1.57 ± 0.25 and from 3.82 ± 0.06 to 2.12 ± 0.08. It also significantly (P < 0.05) improved means of Hb and RBC from 12.25 ± 0.27 and 88.99 ± 5.72 to 12.68 ± 0.18 and 92.91 ± 4.01 and from 10.18 ± 3.00 and 63.39 ± 18.02 to 12.98 ± 0.47 and 95.23 ± 5.32. Body weight increased at 5 mg/kg, from 29.06 ± 1.95 to 32.66 ± 2.10 kg (P < 0.05) while at 3 mg/kg, rectal temperature reduced from 37.35 ± 0.32 to 36.84oC ± 0.23oC (P < 0.05). These results suggest, AMS worsened chloroquine toxicity at 7 mg/kg but potentiated its antiplasmodial activities at the lower doses.

Antibacterial activity of Ampicillin trihydrate formulated in Aluminium-Magnesium Silicate, against <i>Salmonella gallinarum</i>

To test if stabilizing Ampicillin trihydrate (AT) with Aluminium-Magnesium Silicate (AMS) can enhance its antibacterial activities, different concentrations of AT solution and of a formulation of AT in the AMS, were made and used for sensitivity test on Salmonella gallinarum cultures. Also, S. gallinarum-infected chicks were treated with;10 mg/Kg (AT), 10 mg/Kg (AT in AMS), 7.5 mg/Kg (AT), 7.5 mg/Kg (AT in AMS). Mean diameter of inhibition zone, 28.39 ± 2.07 mm produced by AT did not vary significantly (P > 0.05) from 26.36 ± 2.05 mm produced by AT in AMS. However, mean Salmonella gallinarum culture forming units per ml of bile, 17.6 ± 11 × 105of the untreated chicks and 3.4 ± 0.81 × 105(80.58% reduction), 2.4 ± 0.67 × 105(85.70% reduction), 5.4 ± 1.93 × 105(69.20% reduction ) and 0.38 ± 0.13 × 105(97.80% reduction ) of the respective treated groups, showed AMS significantly (P S. gallinarum infection, in vivo.
