## باختصار

مقال بحثي طبي قصير مُخرَج كصفحة مجلة. يستشهد المؤلفون برموز، فيطبع Postext أرقامًا صغيرة مرفوعة في النص ويبني قائمة المراجع المرقّمة في آخره، وكل DOI فيها رابط.

## ما الذي ستنضده

ثلاث صفحات من مجلة سريرية: مقال أصلي يعرض تجربة تمهيدية، منضَّد على A4 في عمودين كما تطبعه مجلات ICMJE. يعبر أعلى الصفحة الأولى شريط ترويسة أخضر مزرق، فوق نوع المقال، وعنوان من ثلاثة أسطر، والمؤلفين بأرقام انتساب مرفوعة، وملخص منظَّم على خلفية باهتة. يستشهد المؤلفون بمفاتيح BibTeX، وتُظهر الصفحات ما يتوقعه محرر طبي: أرقام صغيرة مرفوعة بعد النقطة، والأعمال المتتالية مضمومة في صورة 6–8، وقائمة مراجع مرقّمة بصيغة NLM، *Lancet 2016;387(10022):957–67*، تنتهي بـDOI كل عمل. في ملف PDF ينقلك كل رقم إلى مرجعه ويفتح كل DOI المقالَ. التجربة متخيَّلة؛ أما الأعمال الأحد عشر التي تستشهد بها فحقيقية.

**تجيب هذه الوصفة عن:**

- كيف أضع أرقام استشهاد مرفوعة وروابط DOI فعّالة، كما تفعل المجلات الطبية؟
- كيف أستشهد بالأعمال وأبني قائمة المراجع بأسلوب APA أو IEEE أو أسلوب استشهاد آخر؟

## طريقة التحضير

### 1 · فانكوفر، مرفوعًا ومربوطًا

الشيفرة هي [الجواب المختصر](#الجواب-المختصر) أعلاه. من بين الأساليب المضمَّنة، `elsevier-vancouver` هو الذي يتبع *Citing Medicine* الصادر عن NLM (ترتيب الاستشهاد، والمؤلفون بصيغة *Ettehad D, Emdin CA*، وستة أسماء ثم *et al.*، وعناوين المجلات المختصرة)، فهو الملف الذي تبدأ منه. استبدالان نصيان يقرّبان قائمته من المراجع النموذجية لـNLM: يُكتب الرقم *1.* بدل *[1]*، ويأتي العدد بعد المجلد. يضع `marker: 'superscript'` الاستشهادات أرقامًا مرفوعة أيًّا كان ما يكتبه الأسلوب، ويُبقي `doi: 'link'` كل عنوان `https://doi.org/` رابطًا. أسلوب AMA مضمَّن أيضًا ويرفع أرقامه بنفسه، لكن قائمته تختلف عن فانكوفر في علامات الترقيم ونطاقات الصفحات.

### 2 · كتلة عنوان تمتد عبر العمودين

```js
// script.js, سطرًا 51–80
const text = (id, content, family, size, extra) => ({ kind: 'text', id, content, align: 'left',
  fontFamily: family, fontSize: pt(size), color: col('ink'), overflow: 'wrap', ...extra });
const at = (to, edge, x, y, width) => ({ anchor: { to, edge }, offset: { x: mm(x), y: mm(y) },
  ...(width && { size: { width: mm(width), height: 'auto' } }) });
const caps = { fontFamily: COND, fontWeight: 600, letterSpacing: pt(1.3),
  textTransform: 'uppercase' };
const titleBlock = { enabled: true,
  minHeight: mm(62), // the abstract and the text start under the note, on both columns
  slot: { elements: [
    { kind: 'box', id: 'band', style: { backgroundColor: col('accent') },
      placement: { anchor: { to: 'page', edge: 'top-left' },
        size: { width: 'fill', height: mm(15) } } },
    text('journal', t({ en: 'Almenara Medical Journal', es: 'Revista Médica de Almenara' }),
      COND, 9.5, { ...caps, color: col('paper'), placement: at('page', 'top-left', INNER, 6) }),
    text('issue', '2026 · 14(3) · 181–183', COND, 9.5, { ...caps, color: col('paper'),
      align: 'right', placement: at('page', 'top-right', -OUTER, 6, 60) }),
    text('kind', '{attr.kind}', COND, 9, { ...caps, color: col('accent'),
      placement: at('container', 'top-left', 0, 0, MEASURE) }),
    text('title', '{titleText}', SANS, 19.5, { fontWeight: 600, lineHeight: 1.16,
      placement: at('#kind', 'below', 0, 3, MEASURE - 20) }),
    text('authors', '{attr.authors}', SERIF, 10.5, { inlineMarks: true, // ^1^ → ¹
      placement: at('#title', 'below', 0, 4.5, MEASURE) }),
    text('affiliations', '{attr.affiliations}', SANS, 7.4, { inlineMarks: true,
      lineHeight: 1.35, color: col('muted'), placement: at('#authors', 'below', 0, 2, MEASURE) }),
    { kind: 'rule', id: 'rule', thickness: pt(0.5), color: col('rule'),
      placement: at('#affiliations', 'below', 0, 3, MEASURE) },
    text('note', '{attr.note}', SANS, 7.4, { fontStyle: 'italic', color: col('muted'),
      placement: at('#rule', 'below', 0, 1.6, MEASURE) }),
  ] },
};
```

عنوان المقال هو العنوان الوحيد من المستوى الأول، بالنمط `article`، الذي يمتد عبر الصفحة ويرسمه من تصميمه. يأتي نوع المقال والمؤلفون والانتسابات والملاحظة من خصائص العنوان. يحوّل `inlineMarks` الصيغة `^1^` في الخاصية إلى رقم انتساب مرفوع، ويبدأ `\n` في الانتسابات سطرًا لكل مؤسسة. الشريط مثبَّت إلى حدّ القص، فيبلغ الحافة العليا للورق.

### 3 · ملخص منظَّم وإطار للنقاط الرئيسية

```js
// script.js, سطرًا 84–94
const box = (id, bold, more) => ({ id, border: { enabled: false }, snapToGrid: false,
  marginTop: pt(LEAD), marginBottom: pt(LEAD),
  titleStyle: { ...caps, fontSize: pt(8.5), color: col('accent') }, // run-in labels in bold
  body: { fontFamily: SANS, fontSize: pt(8.3), lineHeight: pt(11.2), textAlign: 'left',
    firstLineIndent: pt(0), paragraphSpacing: true, boldColor: col(bold) }, ...more });
const calloutStyles = [
  box('abstract', 'accent', { background: col('tint'), padding: mm(3.5), marginTop: pt(0) }),
  box('keypoints', 'ink', { backgroundEnabled: false, padding: { top: mm(2.5), right: mm(0),
    bottom: mm(1), left: mm(0) }, stripe: { enabled: true, side: 'top', width: pt(2.5),
    color: col('accent') } }),
];
```

يشترك الإطاران في نمط نص واحد: Fira Sans بحجم 8.3 pt مع تسميات غامقة في أول الفقرة، وهي النبرة التي يتوقعها القارئ لمادة التلخيص. يحمل الملخص خلفية ملوّنة وتسمياته بالأخضر المزرق؛ وتقع النقاط الرئيسية تحت شريط بسمك 2.5 pt وتسمياتها بالحبر. يُبقي `snapToGrid: false` الحشوة دقيقة، فيلتصق إطار الملخص بنصه.

### 4 · الجدول 1 والشكل 1 في رأس العمود

```js
// script.js, سطرًا 298–317
const resources = () => [
  { id: 'tbl-baseline', typeId: 'table', kind: 'table', createdAt: 0, updatedAt: 0,
    placement: { position: 'top' },
    caption: t({ en: 'Characteristics of the patients at baseline.',
      es: 'Características de los pacientes al inicio.' }),
    note: t({ en: 'Values are mean (SD) or number (%). BP, blood pressure, in mm Hg.',
      es: 'Valores en media (DE) o número (%). PA, presión arterial, en mm Hg.' }),
    table: { model: { headerRowCount: 1, columnWidths: [2.2, 1.1, 1.1],
      rows: parseTSV(baseline).rows.map((row, r) => row.map(({ content }, c) => ({ content,
        ...(r === 0 && { isHeader: true }), ...(c > 0 && { align: 'center' }) }))) } } },
  { id: 'fig-home', typeId: 'figure', kind: 'svg', createdAt: 0, updatedAt: 0,
    placement: { position: 'top' }, svg: { fileId: 'home.svg', width: 850, height: 520 },
    caption: t({ en: 'Mean home systolic pressure by week in the telemonitoring group, with its '
      + '95% confidence interval. The dashed line is the home target of 135\u00a0mm\u00a0Hg.',
    es: 'Presión sistólica domiciliaria media por semana en el grupo de telemonitorización, con '
      + 'su intervalo de confianza del 95\u00a0%. La línea discontinua es el objetivo de '
      + '135\u00a0mm\u00a0Hg.' }),
    altText: t({ en: 'A line falling from 158 mm Hg in week 1 to 135 mm Hg in week 12.',
      es: 'Una línea que baja de 158 mm Hg en la semana 1 a 135 mm Hg en la semana 12.' }) },
];
```

يُقرأ الجدول من نص مفصول بعلامات الجدولة، كما يصدّره برنامج الجداول، ويُملأ صف ترويسته بالأخضر المزرق مع تسميات بيضاء غامقة. يطفو الموردان إلى رأس عمود بعد الفقرة التي تستشهد بهما. وحين تُضبط `shortLabel` على الاسم الكامل للنوع يطبع `:ref` *(Table 1)* كما تكتبه المجلات، ويُبقي `numbered: false` على العنوان العدّ عند 1 بدل 1.1.

```js
// script.js, سطرًا 17–21
const palette = { ink: '#1a1d21', accent: '#0d5c63', tint: '#e5eff0', rule: '#9fb4b6',
  muted: '#566065', paper: '#ffffff' };
const col = (id) => ({ hex: palette[id], model: 'hex', paletteId: id });
const colorPalette = Object.entries({ ...palette, 'main-color': palette.accent })
  .map(([id, hex]) => ({ id, name: id, value: { hex, model: 'hex' } }));
```

## الوصفة كاملة

ملف واحد، مركّب من مجلد الوصفة ومعه نص المثال وأدوات دليل الوصفات المشتركة مضمّنة؛ وهو ينشئ صفحته بنفسه. لتشغيله، ضعه داخل `<script type="module">` في صفحة فارغة أو الصقه في لوحة JS في مثال CodePen جديد (وحدةً). يستورد postext من esm.sh، فلا حاجة إلى تثبيت أو بناء.

# Pharmacist-led home blood pressure telemonitoring after an emergency visit for severe hypertension: a pilot randomised trial {style="article" kind="Original article" authors="Lucía Ortega Ramos^1^, Daniel Achterberg^2^, Marta Quiroga Gil^1^, Samuel Okafor^3^" affiliations="^1^ Department of Internal Medicine, Hospital General de Almenara\n^2^ Community Pharmacy Network, Almenara Health Area\n^3^ Primary Care Research Unit, Almenara Health Area" note="Illustrative article written for the Postext Cookbook: the trial, its authors and its data are invented.

:::callout{type="abstract" title="Abstract"}
**Background** Patients discharged from the emergency department after a visit for severe hypertension often wait weeks for a review, and many return with the same readings.

**Methods** In this pilot trial, 120 adults seen for a systolic blood pressure of 180 mm Hg or more were randomised to home telemonitoring with medication titration by a community pharmacist, or to usual care. The primary outcome was office systolic pressure at 12 weeks.

**Results** At 12 weeks, mean systolic pressure was 136.2 mm Hg with telemonitoring and 145.9 mm Hg with usual care (adjusted difference −9.4 mm Hg; 95% CI −13.8 to −5.0). Control below 140/90 mm Hg was reached by 63% and 37% of patients.

**Conclusions** Telemonitoring led by pharmacists lowered blood pressure in the weeks after an emergency visit. A larger trial with cardiovascular outcomes is justified.

## Introduction

High blood pressure is the leading modifiable cause of cardiovascular death. In 2019 about 1.28 billion adults aged 30 to 79 years had hypertension, and fewer than a quarter of them had it under control.[@ncdrisc2021] Each reduction of 10 mm Hg in systolic pressure lowers the risk of major cardiovascular events by about a fifth,[@ettehad2016] and a target below 120 mm Hg prevented more events than one below 140 mm Hg in patients at high risk.[@sprint2015] European guidelines ask for control within three months of starting treatment,[@williams2018] and American ones for a review every month until it is reached.[@whelton2018]

Patients who come to the emergency department with severe hypertension and no acute organ damage are a group the guidelines say little about. Most are sent home with a prescription and a referral to their general practitioner, and the first review may be weeks away. Self-monitoring of blood pressure lowers it when it is combined with a plan for acting on the readings,[@tucker2017; @mcmanus2014; @mcmanus2018] and @margolis2013 showed that pharmacists who adjusted treatment from transmitted home readings improved control for a year in primary care. Whether the same model works in the weeks after an emergency visit has not been tested.

We designed a pilot trial to estimate the effect of pharmacist-led telemonitoring on blood pressure at 12 weeks in this group, and to measure recruitment, retention and safety for a larger trial.

:::callout{type="keypoints" title="Key points"}
**What is already known** Self-monitoring lowers blood pressure when someone acts on the readings, and pharmacists who manage telemonitored readings improve control in primary care.

**What this study adds** After an emergency visit for severe hypertension, telemonitoring with titration by a community pharmacist lowered office systolic pressure by 9.4 mm Hg more than usual care at 12 weeks.
:::

## Methods

### Design and participants

This was a parallel-group, open-label pilot trial with 1:1 allocation, reported according to the CONSORT statement.[@schulz2010] We enrolled adults aged 18 to 80 years discharged from the emergency department of a district general hospital after a visit with a systolic pressure of 180 mm Hg or more, with no acute organ damage, and living within reach of a participating community pharmacy. Patients with secondary hypertension, an estimated glomerular filtration rate below 30 mL/min/1.73 m², pregnancy or a life expectancy under one year were excluded.

### Interventions

Each patient in the telemonitoring group received a validated monitor for the upper arm, which sent every reading to a secure server. They measured twice in the morning and twice in the evening on three days a week. A community pharmacist reviewed the readings weekly and changed treatment by a written protocol agreed with the general practitioners of the area, aiming at a home mean below 135/85 mm Hg. Patients in the usual-care group were referred to their general practitioner, as is routine.

### Outcomes and analysis

The primary outcome was the mean of the second and third of three office systolic readings at 12 weeks, taken by a nurse who did not know the allocation. Secondary outcomes were control below 140/90 mm Hg, return visits to the emergency department and adverse events. Data were collected in REDCap.[@harris2009] The difference between groups was estimated by linear regression adjusted for baseline systolic pressure. With 60 patients per group, the trial had 80% power to detect a difference of 8 mm Hg, assuming a standard deviation of 15 mm Hg and 10% loss to follow-up.

## Results

Between January and June, 163 patients were screened and 120 were randomised; 57 in the telemonitoring group and 57 in the usual-care group attended the 12-week visit. The groups were similar at baseline (:ref{id="tbl-baseline"}). Patients in the telemonitoring group sent a median of 31 sets of readings, and the pharmacists made a median of two changes to treatment per patient.

Home systolic pressure in the telemonitoring group fell most in the first four weeks, and by week 10 it was close to the target (:ref{id="fig-home"}). At 12 weeks, the mean office systolic pressure was 136.2 mm Hg with telemonitoring and 145.9 mm Hg with usual care, an adjusted difference of −9.4 mm Hg (95% CI −13.8 to −5.0). Control below 140/90 mm Hg was reached by 36 of 57 patients (63%) with telemonitoring and by 21 of 57 (37%) with usual care.

Three patients in the telemonitoring group and nine in the usual-care group returned to the emergency department with raised blood pressure. Two patients in the telemonitoring group reported dizziness on standing after a dose increase, and both recovered after the dose was reduced. No serious adverse events were related to the intervention.

## Discussion

In this pilot trial, telemonitoring with titration by a community pharmacist lowered office systolic pressure by about 9 mm Hg more than usual care in the 12 weeks after an emergency visit for severe hypertension. The size of the effect is close to the 10 mm Hg that meta-analysis associates with a fifth fewer cardiovascular events,[@ettehad2016] and it was reached within the three months that European guidelines allow.[@williams2018]

The result agrees with trials of self-monitoring in primary care, where the benefit came from acting on the readings rather than from taking them.[@tucker2017] Pharmacists were well placed to act. They saw the readings every week, they knew the patients from collecting their prescriptions, and the protocol let them change treatment without waiting for an appointment, as the pharmacists did in the trial by @margolis2013 in Minnesota.

The trial has limitations. It was small and open-label, it was run in one health area, and 12 weeks is too short to show an effect on events. The office readings were taken by a nurse blind to the allocation, which limits the bias that an open design invites. Fewer return visits to the emergency department in the telemonitoring group are encouraging, but the numbers are too small for a conclusion.

A multicentre trial powered for return visits and cardiovascular events is the next step. The rates of recruitment and retention seen here, three in four patients screened and 95% retained, suggest that it is feasible.

## أخطاء شائعة

- **ترويسة نمط العنوان تسري على قسمه كله.** header: { elements: [] } في نمط العنوان يزيل الترويسات حتى العنوان المنسَّق التالي، لا في الافتتاحية وحدها. لإبعادها عن الصفحة الأولى وحدها، أعطِ عناصر الترويسة pages: 'body'.
- **أي كائن headings يُلغي فاصل الصفحة قبل H1.** ينتقل H1 افتراضيًا إلى صفحة فردية (always-odd)، لكن تمرير أي كائن headings يعيد ضبط هذا الافتراض، فتتوالى الفصول دون فاصل ولا يفعل span: 'page' شيئًا. أعد كتابة headings.levels[0].breakBefore: { enabled: true, parity } في كل إعداد.
- **النص داخل SVG في <img> لا يستطيع استخدام خطوط الويب.** يُرسَم SVG صورةً، والصورة لا تصل إلى خطوط الويب في الصفحة، فتعود تسمياته إلى خط من النظام. حوّل النص إلى مسارات، أو ضمّن مجموعة فرعية بـ @font-face داخل SVG، أو انقل التسميات إلى التعليق.
- **ترجم Figure/Table بـ defaultResourceTypes(locale).** يضبط locale في الإعداد تقسيمَ الكلمات بالواصلة، لا التعليقات: من دون resourceTypes تقول الأنواع المدمجة Figure وTable بالإنجليزية. مرّر resourceTypes: defaultResourceTypes('es') للإسبانية؛ ولأي لغة أخرى اكتب الأسماء بنفسك في resourceTypes.
- **حمّل كل أوجه الخط قبل الإخراج.** يقيس الإخراج النص بأوجه الخط التي حمّلها المتصفح ويخزّن العروض مؤقتًا، فالوجه الذي يصل بعد البناء الأول يترك فواصل أسطر خاطئة وملف PDF لم يعد يطابق الشاشة. حمّل كل وزن وكل نمط أولًا، واستدعِ clearMeasurementCache() قبل إعادة البناء إذا تأخر وصول أحدها.
- **ضع كل قيمة في الترويسة الأمامية (frontmatter) بين علامتي اقتباس.** يقرأ YAML القيمة title: 1984 رقمًا، ويقرأ التاريخ كائن Date، والقيم غير النصية تُطبع فارغة في العناصر النائبة وتترك ملف PDF بلا عنوان. ضع كل قيمة بين علامتي اقتباس: title: "1984".
- **يُخزَّن الإعداد مؤقتًا بحسب هويته: ابنِ كائنًا جديدًا.** يخزّن المحرّك الإعدادات المحسوبة مؤقتًا بحسب هوية الكائن، فتعديل الإعداد في مكانه ثم البناء مجددًا يعيد استخدام النتيجة القديمة. ابنِ كائنًا جديدًا في كل بناء، ولهذا يكون إعداد الوصفة دالة مصنِّعة: config().

- حين يستشهد النص بعملين رقماهما غير متتاليين، مثل 4 و6، يكتب postext 1.12.1 الرقمين المرفوعين بصيغة *4, 6*، وتتمدد المسافة بعد الفاصلة مع السطر المضبوط. يستشهد هذا المقال بمثل هذه الأعمال في مواضع منفصلة.
- يضبط `labelWidth` إزاحة الأسطر المرحَّلة، لا عمودًا للأرقام: يبدأ السطر الأول بعد الرقم ومسافة. عند 2.85 مم تصطف نصوص المداخل من 1 إلى 9؛ وتبدأ المدخلتان 10 و11 أبعد قليلًا إلى اليمين.
- تسري `header` في نمط العنوان على القسم كله الذي يفتحه ذلك العنوان، فلو وُضع `header: { elements: [] }` على العنوان لأزال الترويسات من كل صفحة حتى العنوان المنمَّط التالي. يكفي `pages: 'body'` على الترويسات لإبعادها عن الصفحة الأولى.
